Use the graph to answer the questionWhat is the average rate of change of f(x) between P and Q?

Given,

The data of the male and female for different age group is shown in question tab.

Required:

The percentage of the female population is made up by the age of group 5- 9.

From the given data,

It is clearly seen that the percentage of female for 5 - 9 age group is 11%.

Hence, the percentage is 11%.

My first step is always to draw a picture

We are told the length is 4 less than twice the width

l = 2w-4

We are told the perimeter is 34

P =2(l+w)

Substitute the first equation in for l

P = 2( 2w-4 + w)

Combine like terms

34 = 2( 3w-4)

Distribute the 2

34 = 6w -8

Add 8 to each side

34+8 = 6w-8+8

42 = 6w

Divide by 6

42/6 = 6w/6

7 =w

Now we can find l

l = 2w-4 = 2(7) -4 = 14-4 = 10

The question asks for the area

A = l*w = 10 *7 = 70

The combine things to make zero means we are combining same thing but off oppoite polarity or sign or direction.

The addition of zero to anything does not make anything to zero, it results in same quantity. So it is a false statement, as addition of zero does not chage anything, it results in original amount.

Let

x ------> number of hours Job A

y -----> number of hours Job B

we have that

x+y=22 ------> x=22-y ------> equation 1

6.40x+6.60y=143.60 ------> equation 2

Solve the system of equations

substitute equation 1 in equation 2

6.40(22-y)+6.60y=143.60

solve for y

140.8-6.40y+6.60y=143.60

0.20y=143.60-140.8

0.20y=2.8

y=14 hours

so

x=22-14=8

therefore

Solution

Let sin (47) = 0.7314. Enter an angle (B), in degrees,

where cos (B) = 0.7314 means

since the vaule of sin(A) = 0.7314

Hence the cos(B) = cos43 = 0.7314

The angle of B = 43°

The simplest form of the expression is:

Donavan has 6x + 1/2 x total number of fishes.

Let Donovan has x number of blue fishes.

Hence the number of red fishes = 5x

The number of gray fishes = 1/2  of x = 1/2 x

Total number of fishes = red + blue + gray = 5x + x + 1/2 x = 6 + 1/2 x

For something like an equation to have any importance, the coefficient involving at least any variable must not be 0. In actuality, the following equation would either be inconsistent (for b ≠ 0) and have no solution, or full n-tuples are solutions, as was mentioned for one variable, if any variable does actually have a zero coefficient.

A regular polynomial over such a field, from which the coefficients are drawn, can also be equalized to zero to produce a linear equation. Since linear equations typically do a good job of representing non-linear systems, they are used extensively in all branches of mathematics as well as in physics and engineering.

Therefore we can infer that Donavan has 6x + 1/2 x total number of fishes.

So we need to express 7 ft 6 in in inches and in feet. For this purpose is important to remember this relation:

So in a we need to express 7ft 6in in inches. This means we must convert the 7ft into inches and then add the result to 6in. If we use the rule of thre we get:

Then we get:

So the answer to part a is 90in.

For part b we can take the result of part a and convert it into feet. Using the rule of three again we get:

Then the answer to part b is 7.5ft.

30% off the prices means that the there is a discount of 30% on the original price.

If 30% discount is given, then it means that the new cost price will be = 100% -30% the original price

=> 70% the original price

Since the Electric Guitar was sold at $315

Then it means that 70% the original price = $315

Let the original price be P

then 70% of P = $315

70% of P = 0.7 x P = 0.7P

Question A.

We can then obtain P, the original price by equatin to $315

=> 0.7P = $315

To get P, divide both sides by the coefficient of P

P = $450

Orignal Price of Guitar = $450

Question B

Amount saved = Original Price - Selling Price

Amount saved = $450 -$315

=> Amount saved = $135

This is the answer, so when n=1

To solve this equation, we can follow the next steps:

First: we can sum similar terms like 3x + 3x.

6(x - 1) = 3x + 3x + 6

6(x - 1) = 6x + 6

Then, solve 6(x-1) using the distributive property:

6x - 6 = 6x + 6

Subtract 6x from both sides of the equation:

6x - 6x - 6 = 6x - 6x + 6

0 - 6 = 6

-6 = 6

Since the result is not congruent, we can say that this equation has no solution.

In order to find the rate of change of the given line, use the following formula:

where (x1,y1) and (x2,y2) are two points of the line.

From the given graph you can select any pair of points, for example:

(x1,y1) = (2,400)

(x2,y2) = (4,1200)

replace the values of the previous coordinates in the formula for m:

Hence, the rate of change is 400

Given the following functions:

f(x) = 3x

g(x) = x + 4

h(x) = x^2 - 1

Before simplifying g(f(-1)), let's first determine f(-1).

f(x) = 3x

f(-1) = 3(-1)

f(-1) = -3

g(x) = x + 4

g(f(-1)) = (-3) + 4

= -3 + 4

g(f(-1)) = 1

Therefore, the answer is 1.

Step-by-step explanation:

This problem describes two points in a route of 4 hours. He went through 68 miles after the first two hours, and 132 miles after 4 hours of driving. We need to calculate the average rate of change.

The average rate of change is the division between the total distance and the time it took to travel that distance, so we have:

The average rate of change is equal to 33 miles per hour.
