(x+24) (x+1)
x=-24. x=-1
Answer: (x+24)(x+1)
Step-by-step explanation:
Factor means to find 2 thing that multiply to the thing before.
x² + 25x + 24
In order to factor you need to find 2 numbers that multiply to the last term, +24 but adds to the middle term, +25.
24 and 1 multiply to +24 but also adds to +25
24 and 1 are you factor numbers that you will use to put into factored form.

A pendulum swings 80cm on its first swing,76cm on its second swing, 72.2 cm on its third swing, and 68.59 cm on its fourth swing what is the distance of the swing at the tenth swing?
The distance of the swing of a pendulum decreases by a constant amount each swing. To find the distance of the swing at the tenth swing, you can use the formula:
distance at nth swing = distance at first swing * (1 - decay factor)^(n-1)
Where decay factor is the fractional decrease in distance per swing. In this case, the decay factor is (80 - 76) / 80 = 0.05. Plugging this into the formula above, we get:
distance at 10th swing = 80 * (1 - 0.05)^9 = 53.78 cm
So the distance of the swing at the tenth swing is approximately 53.78 cm.
exhibit 9-4 a random sample of 16 students selected from the student body of a large university had an average age of 25 years. we want to determine if the average age of all the students at the university is significantly different from 24. assume the distribution of the population of ages is normal with a standard deviation of 2 years. the test statistic is . a. 1.645 b. 2.00 c. 1.96 d. .05
It can be deduced that the mean age is substantially different from 24 at the.05 level of significance.
If the average student age is not substantially different from 24 years, then the null hypothesis is tested, which is:
\(H_{0}\) : μ = 24
If it differs from 24 years, the alternative premise is tested, so:
\(H_{1}\) : μ ≠ 24
The z-distribution is utilized because we have the population's standard deviation. The test statistic comes from:
z = x - μ÷ σ/\(\sqrt{n}\)
The parameters in this issue have the following values:
x(mean) = 25
μ = 24
σ = 2
n=16
As a result, the test statistic's value is:
z = 25-24÷ 2/\(\sqrt{16}\)
z = 2
The probability of a sample mean older than 25 years determines the test's p-value, which is 1 less than the p-value of z = 2.
The p-value for z = 2 in the z-table is 0.9772; 1 - 0.9772 = 0.0228.
Given that the test's p-value is 0.0228 0.05, we may say that:
It can be deduced that the mean age is substantially different from 24 at the.05 level of significance.

Given the following rational functions, find all holes or asymptotes, and intercepts, and graph them. f(x)= x−2
3x−2
Given the following rational functions, find all holes or asymptotes, and intercepts, and graph them. j(x)= x−2
3x−2
4]
The graph approaches the vertical asymptote at x = 2/3 and the horizontal asymptote y = 1/3 as x approaches positive or negative infinity. The function intersects the x-axis at x = 2 and the y-axis at y = 1.
Holes:
Holes occur when a factor in the numerator cancels out with a factor in the denominator. In this case, the factor (x - 2) can cancel out with the factor (3x - 2). To find the value(s) of x where this occurs, we set the denominator equal to zero and solve:
3x - 2 = 0
3x = 2
x = 2/3
So, there is a hole at x = 2/3.
Vertical Asymptotes:
Vertical asymptotes occur when the denominator becomes zero and the numerator is nonzero. In this case, the denominator is 3x - 2. Setting it equal to zero:
3x - 2 = 0
3x = 2
x = 2/3
Therefore, there is a vertical asymptote at x = 2/3.
Horizontal Asymptotes:
To determine the horizontal asymptote(s), we compare the degrees of the numerator and denominator. In this case, the degree of the numerator is 1, and the degree of the denominator is also 1. Since the degrees are equal, we can find the horizontal asymptote by comparing the coefficients of the highest degree terms. The coefficient of x in the numerator is 1, and the coefficient of x in the denominator is 3. Thus, the horizontal asymptote is given by the ratio of the coefficients: y = 1/3.
x-Intercept:
To find the x-intercept, we set the numerator equal to zero and solve:
x - 2 = 0
x = 2
Therefore, there is an x-intercept at x = 2.
y-Intercept:
To find the y-intercept, we set x equal to zero and evaluate the function:
f(0) = (0 - 2)/(3 * 0 - 2) = -2/(-2) = 1
Therefore, there is a y-intercept at y = 1.
Now, let's graph the function f(x) = (x - 2)/(3x - 2):
There is a hole at x = 2/3, so we exclude this point from the graph.
There is a vertical asymptote at x = 2/3.
There is a horizontal asymptote at y = 1/3.
There is an x-intercept at x = 2.
There is a y-intercept at y = 1.
Based on these characteristics, we can plot the graph of f(x):

For each diagram, decide if y is an increase or a decrease of x. Then determine the
percentage.
A
у
B
у
Answer:
A: Decrease, y is 80% of x
B: Increase, y is 160%of x
Step-by-step explanation:
It sounds like it wants to know what percent Y is of X, so if y was 50% of x, that would mean y was half as much of x. so if x was 10 and y was 5
A: x is 5 and y is 4 since y is less it is a decrease. to find the percent do 100*y/x, so in this case that's 100*4/5 =80, so y is 80% of x. and it makes sense it is less than 100% since x is less than y
B: x=5 and y=8 y is greater than x so it is an increase and will be more than 100%. 100*8/5 = 160 so y is 160% of x
A cylinder used for storing spools of thread has a radius of 2 units and a slant height of √29. What is the height of the cylinder?
PLS HELP ASAP!!(show work if can)
Height of cylinder is 5 units
Define Cylinder
One of the most fundamental curvilinear geometric shapes, a cylinder has historically been a three-dimensional solid. It is regarded as a prism with a circle as its base in basic geometry.The volume of the slanted cylinder is V = Base area of cylinder × Height of cylinder⇒ V = (π × radius²) × h
We have given,
Slant height of cylinder = √29
Radius is = 2 units
Now, we to have to calculate the height for that we have the formula
h = √l² - r²
where, l = slant height
r = radius of the circular base
h = height of the cylinder
Now, for the sake of simplicity
h = √l² - r²
h² = l² - r²
Now, plug in the values
h² = (√29)² - 2²
h² = 29 - 4
h² = 25
h = 5

Riya recives a 6% commission for selling newspaper ads. If she sells 15 ads for 50$ each, how much does she earn?
Riya earns $45 in commission for selling 15 newspaper ads at $50 each.
A commission is a charge or payment given to a person or group in exchange for a good or service. When selling goods or services on behalf of a corporation, sales representatives or agents are frequently compensated with commissions in the business world. For instance, a stockbroker may receive a fee for carrying out a trade on behalf of a customer, while a real estate agent may receive a commission depending on the sale price of a property they assist in selling.
Riya receives a 6% commission for selling newspaper ads, and if she sells 15 ads for $50 each, her total earnings can be calculated as follows:
Total earnings = Total sales x Commission rate
The total sales from selling 15 ads at $50 each are:
Total sales = 15 x $50 = $750
The commission rate is 6%, which can be written as 0.06 as a decimal.
Plugging these values into the formula, we get:
Total earnings = $750 x 0.06 = $45

Find the slope
Change in y over the change in x
\(\frac{13-11}{4-3}\) = \(\frac{2}{1}\) = 2
slope (m) is 2.
Part A
Find the y -intercept
m = 2
x = 3 from the point (3,11)
y = 11 from the point (3,11)
y = mx + b Substitute what I know and solve for b
11 = (2)(3) + b
11 = 6 + b Subtract 6 from both sides
11 - 6 = 6 -6 + b
5 = b
The y intercept (b) is 5
y = mx + b
y = 2x + 5
Part B
y = 2x + 5
1015 = 2x + 5 Subtract 5 from both sides
1015 - 5 = 2x + 5 - 5

an american society of investors survey found 30% of individual investors have used a discount broker. in a random sample of nine individuals, what is the probability:
The probability of at most six individuals in the sample having used a discount broker is calculated to be approximately 0.997.
To solve this problem, we need to use the binomial distribution formula. Let X be the number of individuals in the sample who have used a discount broker. Then, X follows a binomial distribution with parameters n = 9 and p = 0.3.
The probability of at most six individuals in the sample having used a discount broker can be calculated as follows:
P(X ≤ 6) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 6)
Using a binomial probability table or calculator, we can find the individual probabilities and sum them up. Alternatively, we can use a normal approximation to the binomial distribution if the sample size is large enough (np and n(1-p) are both greater than 5).
Using the normal approximation, we have:
mean = np = 9 x 0.3 = 2.7
variance = np(1-p) = 9 x 0.3 x 0.7 = 1.89
standard deviation = √(variance) = 1.374
To standardize the distribution, we calculate the z-score:
z = (6.5 - 2.7) / 1.374 = 2.75
Using a standard normal distribution table or calculator, we find that the probability of a z-score less than or equal to 2.75 is approximately 0.997.
Therefore, the probability of at most six individuals in the sample having used a discount broker is approximately 0.997.

whats -7m(1.2m – 2) + (-6m)
Answer:
-7m(1.2m - 2) + (-6m) = -8.4m² + 8m
Step-by-step explanation:
Let us simplify the given expression
∵ The expression is -7m(1.2m - 2) + (-6m)
→ At first multiply the bracket by -7m
∵ -7m(1.2m - 2) = (-7m)(1.2m) - (-7m)(2)
∴ -7m(1.2m - 2) = -8.4m² - (-14m)
→ Remember (-)(-) = (+)
∴ -7m(1.2m - 2) = -8.4m² + 14m
→ Substitute it in the expression above
∵ -7m(1.2m - 2) + (-6m) = -8.4m² + 14m + (-6m)
→ Remember (+)(-) = (-)
∴ -7m(1.2m - 2) + (-6m) = -8.4m² + 14m - 6m
→ Add the like terms
∵ -7m(1.2m - 2) + (-6m) = -8.4m² + (14m - 6m)
∴ -7m(1.2m - 2) + (-6m) = -8.4m² + 8m
Based on historical data at Oxnard college, they believe that 34% of freshmen do not visit their advisors regularly. For this year, you would like to obtain a new sample to estimate the proportion of freshmen who do not visit their advisors regularly. You would like to be 95% confident that your estimate is within 4% of the true population proportion. How large of a sample size is required?
A sample size of at least 538 freshmen to estimate the proportion of freshmen who do not visit their advisors regularly with a margin of error of 4% and a confidence level of 95%.
To answer your question, we need to use the formula for sample size calculation for proportion:
n = [(Z-score)^2 * p(1-p)] / E^2
Where:
n = required sample size
Z-score = the critical value for the desired confidence level (95% confidence level corresponds to a Z-score of 1.96)
p = the estimated population proportion (34% or 0.34)
1-p = the complement of p
E = the desired margin of error (4% or 0.04)
Plugging in the values:
n = [(1.96)^2 * 0.34(1-0.34)] / (0.04)^2
Simplifying the equation:
n = [(3.8416) * 0.2244] / 0.0016
n = 537.38
We need a sample size of at least 538 freshmen to estimate the proportion of freshmen who do not visit their advisors regularly with a margin of error of 4% and a confidence level of 95%. Keep in mind that this is just an estimate based on the historical data and assumes that the population proportion has not changed significantly.

The first two steps in determining the solution set of the system of equations, y = x2 – 6x + 12 and y = 2x – 4, algebraically are shown in the table.
Which represents the solution(s) of this system of equations?
(4, 4)
(–4, –12)
(4, 4) and (–4, 12)
(–4, 4) and (4, 12)
Answer:
(4,4)
Step-by-step explanation:
The solution set of the system of equations can be found by setting the two equations equal to each other and solving for x.
x^2 - 6x + 12 = 2x - 4
x^2 - 8x + 16 = 0
(x - 4)^2 = 0
x = 4
Since both equations in the system are equal to y, we can substitute x = 4 into either equation to find the corresponding value of y.
y = 2x - 4 = 2(4) - 4 = 4
Therefore, the solution of this system of equations is (4, 4).
Therefore, the correct answer is (4, 4).

Draw a Bode plot for: 2572
L(s)= 2572/ (s+45.3)(s+341)
we can draw the Bode plot for the given transfer function L(s) = 2572/((s + 45.3)(s + 341)).
To draw the Bode plot for the transfer function L(s) = 2572/((s + 45.3)(s + 341)), we need to plot the magnitude and phase response as a function of frequency.
Step 1: Convert the transfer function to the standard form:
L(s) = K / ((s + z1)(s + z2))
where K = 2572, z1 = -45.3, and z2 = -341.
Step 2: Calculate the corner frequencies:
The corner frequencies are the values of s where the denominator of the transfer function becomes zero. In this case, the corner frequencies are z1 = -45.3 and z2 = -341.
Step 3: Draw the Bode plot:
a) Magnitude plot:
- At low frequencies (ω << corner frequencies), the magnitude is approximately constant (0 dB).
- At high frequencies (ω >> corner frequencies), the magnitude decreases at a rate of -20 dB/decade for each pole.
- At the corner frequencies, there will be a downward slope of -20 dB/decade for each pole starting from 0 dB.
b) Phase plot:
- At low frequencies (ω << corner frequencies), the phase is approximately 0 degrees.
- At high frequencies (ω >> corner frequencies), the phase decreases at a rate of -90 degrees/decade for each pole.
- At the corner frequencies, there will be a phase shift of -45 degrees for each pole.
Using the above information, we can draw the Bode plot for the given transfer function L(s) = 2572/((s + 45.3)(s + 341)).
