Figure I and Figure II are similar pentagons.


Which proportion must be true?

Answer:

There is no short answer.

Step-by-step explanation:

To find to intervals which f(x) increases or decreases, we first need to find it's derivative.

\(f(x) = sinx - cosx\\f'(x) = cosx - (-sinx) = cosx + sinx\)

The function is increasing when it's value is  > 0 and decreasing when it's value is < 0.

If we take a look at this graph, cosx+sinx is positive when they are both positive or when cosx is greater then sinx on the negative part.

I hope this answer helps.

Answer:

  2. correct

  3. addition property of equality

  4. substitution property of equality

Step-by-step explanation:

You're asked for the Reasons, so you need to examine the Statements to see how you get from one line to the next.

The first line of Statement 2 differs from Statement 3 in that m∠GHI has been added to both sides of the equation (ignoring the typo in statement 3). The reason you can add the same thing to both sides of an equation is given by the Addition Property of Equality.

Statement 3 differs from Statement 4 in that one of the m∠GHI has been replaced by m∠JKL. We can do this replacement because those measures are equal to each other. Replacement of equals by equals is allowed by the Substitution Property of Equality.

Given that the sample contains 6 students, so the sample size will be,

Let the success of the experiment is defined as the event that a randomly selected adult uses a smartphone in meetings or classes. And 'x' be the random variable representing the number of successes.

Given that 58% of the adults use a smartphone in meetings and classes. So there will be 58% chance that a randomly selected adult uses a smartphone in meetings and classes.

So, the probability of success will be,

Then, the probability of getting exactly 'x' successes, is given by,

So, the probability of exactly 3 successes will be,

Thus, there is 28.91% probability that exactly 3 of them use their smartphones in meetings or classes.

Step-by-step explanation:

60=4d-8

We move all terms to the left:

60-(4d-8)=0

We get rid of parentheses

-4d+8+60=0

We add all the numbers together, and all the variables

-4d+68=0

We move all terms containing d to the left, all other terms to the right

-4d=-68

d=-68/-4

d=17

The value of x that makes the line containing (1,2) and (5,3) perpendicular to the line containing (x,4) and (3,0) is x = 2.

To determine the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0), we need to find the slope of both lines and apply the concept of perpendicular lines.

The slope of a line can be found using the formula:

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

For the line containing (1,2) and (5,3), the slope is:

slope1 = (3 - 2) / (5 - 1) = 1 / 4

To find the slope of the line containing (x,4) and (3,0), we use the same formula:

slope2 = (0 - 4) / (3 - x) = -4 / (3 - x)

Perpendicular lines have slopes that are negative reciprocals of each other. In other words, if the slope of one line is m, then the slope of a line perpendicular to it is -1/m.

So, we can set up the equation:

-1 / (1/4) = -4 / (3 - x)

Simplifying this equation:

-4 = -4 / (3 - x)

To remove the fraction, we can multiply both sides by (3 - x):

-4(3 - x) = -4

Expanding and simplifying:

-12 + 4x = -4

Adding 12 to both sides:

4x = 8

Dividing both sides by 4:

x = 2

Answer:

The washer costs 220 and the dryer costs 376! brainliest pls!

Step-by-step explanation:

The statement y is a function of x as shown is TRUE.

Functions are expressed in terms of variables. We have the dependent variable and the independent variable. The variable y expressed as a function of x is written as y = f(x)

where

y is the dependent

x is the independent

From the given equation y = 3/x + 3, since y is depending on the variable 'x', hence y is a function of the variable x. The statement is TRUE.

Step-by-step explanation:

The standard form of the equation of an ellipse with major axis on the y axis is given as:

\(\frac{(x-h)^2}{b^2} +\frac{(y-k)^2}{a^2} =1\)

Where (h, k) is the center of the ellipse, (h, k ± a) is the major axis, (h ± b, k) is the minor axis, (h, k ± c) is the foci and c² = a² - b²

Since the minor axis is at (37,0) and (-37,0), hence k = 0, h = 0 and b = 37

Also, the foci is at (0,5) and (0, -5), therefore c = 5

Using c² = a² - b²:

5² = a² - 37²

a² = 37² + 5² = 1369 + 25

a² = 1394

Therefore the equation of the ellipse is:

\(\frac{x^2}{1369}+ \frac{y^2}{1394} =1\)

Step-by-step explanation:

Chay can use 3 bags of mulch per flower bed.

Chay is buying mulch for the zoo's summer flower beds. She has enough in her budget to purchase 55 bags of mulch. If there are 20 flower beds, how many bags of mulch can be used in each flower bed?The number of bags of mulch that can be used in each flower bed can be found by dividing the total number of bags of mulch by the number of flower beds, as given by the problem.Let X be the number of bags of mulch used in each flower bed. Then, the following equation can be written:Total number of bags of mulch = X × number of flower beds (20)Or, 55 = 20XDividing both sides of the equation by 20, we get: X = 55/20X = 2.75.Therefore, Chay can use 2.75 bags of mulch in each flower bed. However, since we cannot have a fraction of a bag of mulch, she would have to round up to 3 bags of mulch per flower bed to ensure each flower bed has enough mulch.

To find the measure of angle AB, we can use the fact that the sum of the angles in a triangle is 180 degrees.

Given:

Angle A = 65 degrees

Angle B = 91 degrees

We can subtract the sum of these two angles from 180 degrees to find angle AB:

Angle AB = 180 - (Angle A + Angle B)

Angle AB = 180 - (65 + 91)

Angle AB = 180 - 156

Angle AB = 24 degrees

Therefore, the measure of angle AB is 24 degrees.

The equation for the transformed function g(x) is: g(x) = 2.323 (4) raise to the power x-0.872/2

How to solve a function?

If the function f(x) is vertically compressed by a factor of 1/2, the equation for the new function g(x) is given by:

g(x) = a(4) raise to the power x-k/2

where "a" and "k" are constants that need to be determined. To find these constants, we can use the fact that the original function f(x) is equal to g(x) when the compression is applied:

f(x) = g(x)/2

Substituting the expression for g(x) into this equation and simplifying, we get:

4raise to the power x - 6 = a(4)raise to the power x-k/2

To solve for "a" and "k", we need to find two equations involving these variables. One way to do this is to evaluate the expression for f(x) at two different values of x, and then set those equal to the corresponding values of g(x)/2. For example, we can choose x = 0 and x = 1:

f(0) = 4 - 6 = -5

f(1) = 4- 6 = -2

Using the equation g(x)/2 = f(x), we can write:

g(0)/2 = -5

g(1)/2 = -2

Substituting the expression for g(x) into these equations, we get:

a(4) raise to the power -k/2 = -10

a(4) raise to the power 1-k/2 = -4

Taking the ratio of these two equations, we can eliminate the variable "a" and solve for "k":

(4)raise to the power -k/2 / (4)  raise to the power 1-k/2 = -10 / -4

Simplifying this equation, we get:

4.raise to the power(1-k/2) = 5

Taking the logarithm of both sides (with base 4), we get:

1-k/2 = log4(5)

Solving for "k", we get:

k = 2 - 2 log4(5)

Substituting this value of "k" back into one of the equations we derived earlier, we can solve for "a":

a = -10 / (4)   raise to the power  -k/2

Substituting the numerical value of "k", we get:

k = 2 - 2 log4(5) ≈ 0.872

a = -10 / (4) raise ti the power  -k/2 ≈ 2.323

Therefore, the equation for the transformed function g(x) is:

g(x) = 2.323 (4)raise to the power x-0.872/2

or equivalently:

g(x) = 1.1615 (4) raise to the power -x0.872

Jessica is able to select from 32 different class sets as a result.

A determiner is a member of the set of words used to change words or their synonyms. Determiners are typically used in front of descriptors to help make it clearer to whom or what a noun refers. For example, are you're interested in buying this new book? This acts as a determining word.

Jessica must select one class in each of the 4 groups, thus we can count the possibilities by multiplying the number of ways Jessica can select 1 class from each category.

Jessica has 2 options under the economics heading.

The 2 most popular classes in the mathematics category are filled, so she must select from the 1 remaining class.

There are 4 options in the schooling category for her.

She has 4 options under the sociology area.

As a result, Jessica is permitted to enroll in a total of:
