how do you find the y intercept on a table
Answer:
y-intercept is 10. The y-intercept is where the line crosses with the y-axis line. The y-axis line is when x = 0.
A construction company purchases a crane for $450,000. An accountant for the company figures the crane loses 30% of its value every year. The value of the crane can be computed after x years using the function V ( x ) = 450 , 000 ( 1 − 0.3 ) x . Use the graph to answer the following questions What is the value after 5 years? cells When will the value decline below $140000? (round to the nearest tenth).
The value of the company after 5 years is given as follows:
$75,631.5.
The value will decline below $140,000 when:
3.27 years.
What is the exponential function?The exponential function for this problem is defined as follows:
V(x) = 450000(0.7)^x.
The value after 5 years is found replacing the lone instance of x by 5, hence:
V(5) = 450000(0.7)^5
V(5) = $75,631.5.
The value will decline below $140,000 when at x for which V(x) = 140000, hence:
140000 = 450000(0.7)^x.
(0.7)^x = 140000/450000
(0.7)^x = 0.311111
xlog(0.7) = log(0.311111)
x = log(0.311111)/log(0.7)
x = 3.27 years.

Consider the following equation.
y = x^3 + 5
Test for symmetry. (select all that apply)
1. x-axis symmetry
2. y-axis symmetry
3. origin symmetry
4. no origin symmetry
Graph the equation.
Answer:
4. no origin symmetry-----------------------------
Given function:
y = x³ + 5Graph it first (see attached).
Test the graph for symmetry.
We know the odd degree parent function y = x³ has an origin symmetry, whilst even degree functions may have axis symmetry.
The given function is a translation of cubic function 5 units up so the center of symmetry has translated as well. Therefore correct answer is 4.
Answer:
4. no origin symmetry
Step-by-step explanation:
Functions are symmetric with respect to the x-axis if for every point (a, b) on the graph, there is also a point (a, −b) on the graph:
f(x, y) = f(x, −y)To determine if a graph is symmetric with respect to the x-axis, replace all the y's with (−y). If the resultant expression is equivalent to the original expression, the graph is symmetric with respect to the x-axis.
\(\begin{aligned}&\textsf{Given}: \quad &y &= x^3 + 5\\&\textsf{Replace $y$ for $(-y)$}: \quad &-y &= x^3 + 5\\&\textsf{Simplify}: \quad &y &= -x^3 - 5\end{aligned}\)
Therefore, since the resultant expression is not equivalent to the original expression, it is not symmetric with respect to the x-axis.
--------------------------------------------------------------------------------------------------
Functions are symmetric with respect to the y-axis if for every point (a, b) on the graph, there is also a point (-a, b) on the graph:
f(x, y) = f(-x, y)To determine if a graph is symmetric with respect to the x-axis, replace all the x's with (−x). If the resultant expression is equivalent to the original expression, the graph is symmetric with respect to the y-axis.
\(\begin{aligned}&\textsf{Given}: \quad &y&=x^3+5\\&\textsf{Replace $x$ for $(-x)$}: \quad &y&=(-x)^3+5\\&\textsf{Simplify}: \quad &y&=-x^3+5\end{aligned}\)
Therefore, since the resultant expression is not equivalent to the original expression, it is not symmetric with respect to the y-axis.
--------------------------------------------------------------------------------------------------
Functions are symmetric with respect to the origin if for every point (a, b) on the graph, there is also a point (-a, -b) on the graph:
f(x, y) = f(-x, -y)To determine if a graph is symmetric with respect to the origin, replace all the x's with (−x) and all the y's with (-y). If the resultant expression is equivalent to the original expression, the graph is symmetric with respect to the origin.
\(\begin{aligned}&\textsf{Given}: \quad &y&=x^3+5\\&\textsf{Replace $x$ for $(-x)$ and $y$ for $(-y)$}: \quad &(-y)&=(-x)^3+5\\&\textsf{Simplify}: \quad &-y&=-x^3+5\\&&y&=x^3-5\end{aligned}\)
Therefore, since the resultant expression is not equivalent to the original expression, it is not symmetric with respect to the origin.
A table is being sold for 67% off the regular price the sale price is $536 what is the regular price
Answer:
Step-by-step explanation:
Use a simple Equation
Price = Number x Price
So Price = 536.
Since it was 67% off we multiple the price of the original by .67.
So
536 = .67x
Solve for x = 536/.67 = 800
The original Price is $800.
check by multiplying by the sale %.
-7(5-3x)=-35 what is the x in the problem
Answer:
x = 0
Step-by-step explanation:
-7(5-3x)=-35
Divide by -7
-7/-7(5-3x)=-35/-7
5 -3x = 5
Subtract 5 from each side
5-3x-5 = 5-5
-3x=0
Divide by -3
x=0
Answer: x = 0
Step-by-step explanation: Start by distributing the -7 through the parenthses on the left side of the equation.
-7(5) is -35 and -7(-3x) is 21x.
So we have -35 + 21x = -35.
Next, isolate the x term by adding 35 to both sides.
When we do this, we get 21x = 0.
Now divide both sides by 21 and x = 0.

=> 2x = 2
=> x = 2/2
=> x = 1

Answer:
x=1
Step-by-step explanation:
Hi there!
2x+3=5
Our goal is to isolate x on one side of the equal sign, and we can do this using inverse operations. For example, the inverse operation of addition is subtraction. Subtract both sides of the equation by 3 to isolate 2x:
2x+3-3=5-3
2x=2
The inverse of multiplication is division. Divide both sides by 2:
2x÷2=2÷2
x=1

at a large university, 68% of the students have a laptop, while only 43% of professors have one. let p hat subscript s and p hat subscript p be the sample proportions of students and professors, respectively, who have a laptop. suppose 56 students and 31 professors from this university are selected at random and asked if they have a laptop. which of the following is the correct calculation and interpretation of the standard deviation of the sampling distribution of p hat subscript s baseline minus p hat subscript p ?
The correct calculation of the standard deviation of the sampling distribution of p_hat subscript s - p_hat subscript p is 0.0934.
What do you mean by standard deviation?
In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of population
N = number of observation of population
X = mean
μ = population mean
We are given that;
Percentage of students with laptop=68%
Percentage of professors with laptop=43%
p_s = 0.68 and p_p = 0.43.
Now,
The formula for the standard deviation of the sampling distribution of the difference between two sample proportions is:
sqrt[(p_s * (1 - p_s) / n_s) + (p_p * (1 - p_p) / n_p)]
where p_s and p_p are the population proportions of students and professors who have a laptop, respectively, n_s and n_p are the sample sizes of students and professors, respectively.
We are also given that 56 students and 31 professors were selected at random and asked if they have a laptop. Therefore, n_s = 56 and n_p = 31.
Substituting these values into the formula, we get:
sqrt[(0.68 * (1 - 0.68) / 56) + (0.43 * (1 - 0.43) / 31)]
sqrt[0.00367143 + 0.00505484]
= sqrt(0.00872627)
= 0.0934 (rounded to four decimal places)
Therefore, by standard deviation the answer will be 0.0934.

determine the inclination of the following straight line
1. y=x+3 2) 3x-2y = 6
The inclination of the line represented by the equation y = x + 3 is 1, and the inclination of the line represented by the equation 3x - 2y = 6 is 3/2.
To determine the inclination (or slope) of a straight line, we can examine the coefficients of the variables x and y in the equation of the line.
The inclination represents the ratio of how much y changes with respect to x.
Equation: y = x + 3
In this equation, the coefficient of x is 1, which means that for every increase of 1 in x, y also increases by 1.
This indicates that the inclination of the line is positive, meaning it slopes upwards as x increases.
Since the coefficient of x is 1, the inclination can be expressed as 1/1 or simply 1.
Equation: 3x - 2y = 6
To determine the inclination, we need to rearrange the equation in slope-intercept form (y = mx + b), where m represents the slope.
First, isolate y:
-2y = -3x + 6
Divide the entire equation by -2 to solve for y:
y = (3/2)x - 3
Now we can observe that the coefficient of x is 3/2.
This indicates that for every increase of 1 in x, y increases by 3/2. Therefore, the inclination of this line is positive, indicating an upward slope.
The inclination can be expressed as 3/2.
