Answer:

The three angles are 40°, 75°, 65°

Step-by-step explanation:

Assume that the first angle is x

∵ The second angle is 35° more than the first angle

∴ The second angle is x + 35

∵ The third angle is 25° more than the first angle

∴ The third angle is x + 25

∵ The sum of the angles of a triangle is 180°

→ Add the three angles and equate the sum by 180°

∵ x + x + 35 + x + 25 = 180

→ Add the like terms in the left side

∴ (x + x + x) + (35 + 25) = 180

∴ 3x + 60 = 180

→ Subtract 60 from both sides

∴ 3x + 60 - 60 = 180 - 60

∴ 3x = 120

→ Divide both sides by 3 to find x

∴ x = 40

→ Find each angle by substitute x by 40

∵ First angle = x

∴ The first angle = 40°

∵ Second angle = x + 35

∴ The second angle = 40 + 35 = 75°

∵ Second angle = x + 35

∴ The third angle = 40 + 25 = 65°

∴ The three angles are 40°, 75°, 65°

Step-by-step explanation:

x2 + y2 = r2

Answer:k=10

Step-by-step explanation:

The question is asking for the roots of the polynomial f(x) = 5x4 - 2x3 - 25x2 - 6x + 45. Therefore, the roots of f(x) = 5x4 - 2x3 - 25x2 - 6x + 45 are approximately -1.2 and 1.6.

To find the roots of a polynomial, we need to set f(x) equal to zero and solve for x. This means we are looking for values of x that make the equation f(x) = 0 true. We can do this through factoring or by using numerical methods such as the quadratic formula or Newton's method. To find the roots of f(x) = 5x4 - 2x3 - 25x2 - 6x + 45, we can use various methods. One approach is to try to factor the polynomial.

However, it is not immediately clear how to factor this polynomial, so we can turn to numerical methods. One way to find the roots is to use a graphing calculator or software to plot the function and look for the x-intercepts (where the function crosses the x-axis). This can give us an approximate idea of where the roots are located. Another method is to use iterative numerical techniques such as Newton's method or the bisection method to find the roots with increasing accuracy.

A standard normal distribution is a normal distribution with a mean of zero and a standard deviation of one. Option A is the correct answer.

The standard normal distribution, often known as the z-distribution, is a special sort of ordinary distribution with a mean of zero and a standard deviation of one. Option A is the correct answer.

Any normal distribution can be standardized through transforming its values into z scores. The Z scores indicate how many standard deviations a certain result is from the mean. All normal distributions are unimodal, symmetrically distributed, and have a bell-shaped curve. One such distribution is the common normal distribution. On the other hand, a normal distribution's mean and standard deviation can be any value. In the typical normal distribution, the mean and standard deviation remain constant.

Driving a personal car would be the most cost-effective mode of transportation for this commute, with a total daily cost of approximately $4.60 ($3.60 for gas + $1 for travel time).

Based on the given information, the most cost-effective mode of transportation for this commute would be to drive a personal car. Taking public transportation or carpooling may be more environmentally friendly options, but they may not save as much money as driving alone.

Assuming an average speed of 60 miles per hour on the highway, the commute would take approximately 20 minutes each way, or 40 minutes round-trip. This means the total cost of travel time for each workday would be $40 ($60/hour x 2/3 hour).

Using a cost calculator such as GasBuddy, we can estimate that the cost of driving 20 miles per day (round-trip) would be around $3.60 per day, assuming an average fuel efficiency of 25 miles per gallon and a gasoline price of $2.50 per gallon.

we need to understand the concept of probability and how it is related to the mean and emissions. Probability is the likelihood or chance of an event occurring.

In this case, the event is the number of alpha particle emissions of carbon-14 counted by a Geiger counter per second. The mean is the average value of these emissions. The question asks us to find the probability that it takes no longer than 1 second for the second count.

This means that we need to find the probability of observing a count of alpha particle emissions equal to or less than the mean value of 25 in one second.

We can use the Poisson distribution to calculate this probability. The Poisson distribution is used to model the number of occurrences of an event in a given time period or space.

It assumes that the occurrences are independent and random, and that the mean and variance of the distribution are equal. In this case, the mean and variance are both 25.

Using the Poisson distribution formula, we can calculate the probability of observing a count of alpha particle emissions equal to or less than 25 in one second.

The formula is: P(X ≤ 25) = e^(-λ) * Σ(λ^k / k!), where λ is the mean value, k is the number of occurrences, and Σ is the sum from k=0 to k=25. Plugging in the values, we get: P(X ≤ 25) = e^(-25) * Σ(25^k / k!) Using a calculator, we can evaluate this sum and get: P(X ≤ 25) = 0.3841.

Therefore, the probability of observing a count of alpha particle emissions equal to or less than 25 in one second is 0.3841 or 38.41%. In conclusion,

the probability of observing a count of alpha particle emissions equal to or less than the mean value of 25 in one second is 0.3841. This means that there is a 38.41% chance of observing this event in one second.

The probability of washing dishes by me tonight will take between 15 and 16 minutes is 14.29%.

The term "uniform distribution" refers to a type of probability distribution in which the likelihood of each potential result is equal.

Let's consider, the lower limit for this distribution as a and the upper limit for this distribution as b.

The following formula gives the likelihood that we will discover a value for X between c and d,

\(P(c\leq X\leq d)=\frac{d-c}{b-a}\)

Given the time it takes me to wash the dishes is 11 minutes and 18 minutes. From this, a = 11 and b = 18.

Then,

\(P(15\leq X\leq 16)=\frac{16-15}{18-11}=0.1429=14.29\%\)

The answer is 14.29%.

Based on the results, we can observe that as x approaches 2, the slopes of PQ are getting closer to 4. Therefore, we can guess that the slope of the tangent line to the curve at P(2,12) is approximately 4.

To find the slope of the secant line PQ, we need to determine the coordinates of point Q and then calculate the slope using the formula:

slope = (change in y) / (change in x)

Given that Q is the point (x, x^2 + x + 6), we can substitute the values of x to find the corresponding slopes.

If x = 2.1:

Q = (2.1, (2.1)^2 + 2.1 + 6) = (2.1, 12.51)

Slope of PQ = (12.51 - 12) / (2.1 - 2) = 0.51 / 0.1 = 5.1

If x = 2.01:

Q = (2.01, (2.01)^2 + 2.01 + 6) = (2.01, 12.0601)

Slope of PQ = (12.0601 - 12) / (2.01 - 2) = 0.0601 / 0.01 = 6.01

If x = 1.9:

Q = (1.9, (1.9)^2 + 1.9 + 6) = (1.9, 11.61)

Slope of PQ = (11.61 - 12) / (1.9 - 2) = -0.39 / -0.1 = 3.9

If x = 1.99:

Q = (1.99, (1.99)^2 + 1.99 + 6) = (1.99, 11.9601)

Slope of PQ = (11.9601 - 12) / (1.99 - 2) = -0.0399 / -0.01 = 3.99

Based on the results, we can observe that as x approaches 2, the slopes of PQ are getting closer to 4. Therefore, we can guess that the slope of the tangent line to the curve at P(2,12) is approximately 4.

360 degrees equals a circle. A circle can be divided into more manageable pieces. A circle's circumference is referred to as an arc, and an arc is given a name based on its angle.

Having no sides or edges, a circle is a figure with a round shape. A closed, two-dimensional curved form is what is meant by the term "circular" in geometry. The shape of a car tire, a wall clock that indicates the time, and a lollipops are a few objects that are circular in nature. The collection of all points in the plane that make up a circle are all equally spaced from a certain point known as the "centre," making the form a closed two-dimensional shape.

The reflection symmetry line is created by all lines that traverse the circle. Additionally, it is symmetrical in rotation around the center at all angles. A curved line forms a circle, a two-dimensional shape. The curving line's tips are evenly spaced apart from the center since it is a sphere.
