Answer 1
Answer:    536

============================================================

Explanation:

The average rate of change is the same as the slope of the line through the endpoints mentioned.

The interval [6, 8] means that we're talking about [tex]6 \le x \le 8[/tex]

When x = 6, we have y = f(x) = 1178When x = 8, we have y = f(x) = 2742

So we're tasked to find the slope of the line through (6,1178) and (8,2742)

We'll use the aptly named slope formula.

[tex](x_1,y_1) = (6,1178) \text{ and } (x_2,y_2) = (8,2742)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{2742 - 1178}{8 - 6}\\\\m = \frac{1564}{2}\\\\m = 782\\\\[/tex]

The slope through those two endpoints is 782, which is the average rate of change on the interval [6, 8].

------------------

For the interval [5,7] we have [tex]5 \le x \le 7[/tex]

According to the function table,

When x = 5, y = 690When x = 7, y = 1852

Like before, use the slope formula to find the slope through (5,690) and (7,1182)

[tex](x_1,y_1) = (5,690) \text{ and } (x_2,y_2) = (7,1182)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1182 - 690}{7 - 5}\\\\m = \frac{492}{2}\\\\m = 246\\\\[/tex]

This is the average rate of change on the interval [5,7].

------------------

The last step is to subtract the slopes:

782 - 246 = 536 which is the final answer

Shelly would need 5 pounds of grass seed to plant in her backyard.

What is an area?

Area is the amount of space occupied by a two dimensional shape or figure.

From the image:

Area of the backyard = (10 + 15) * (10 + 20) = 750 ft²

Area of triangle = (1/2) * 10 * 10 = 50 ft²

Area of small rectangle = (25 - 20) * (30 - 15) = 75 ft²

Area of shaded part = 750 - 50 - 75 = 625 ft²

1 pound of grass seed covers 125 ft², for 625 ft²:

Amount of seed = 625 ft² * 1 pound per 125 ft²  = 5 pound

Step-by-step explanation:

The answer is 33/5.

To multiply fractions, you multiply the numerators to get the numerator of the product and multiply the denominators to get the denominator of the product and then simplify the product. Also, you can make a whole number, which is 28 in this case, into a fraction by putting it over 1. So, that would be 28/1.

First, I multiplied the numerators:

4(11)(28)(9) = 11088

Next, multiply the denominators (and im assuming that last one is a 48, its a bit covered up by the mouse):

5(7)(1)(48) = 1680

So that's 11088/1680

Lastly, you simplify this to get 33/5 (I just used desmos scientific calculator for all of this)

Katrina drove 165 miles in 3 hours. At this rate, how far can she drive in 7 hours?

Answers

Answer:

385 miles

Step-by-step explanation:

Let's start by finding the unit rate (how far she can drive in 1 hour):

[tex]\frac{165mi}{3hr}[/tex]

Divide both the numerator and the denominator by 3 hours (Please note that this is essentially dividing the fraction by 1, so we are only simplifying the fraction, not changing it):

[tex]55mi/hr[/tex]

Now, using a unit converter, we can find out far she can drive in 7 hours:

[tex]7hr(\frac{55mi}{1hr})=7*55mi=385mi[/tex]

She can drive 385 miles in 7 hours

Katrina can drive 1,155 miles in 7 hours.

Answer:

[tex]38/83= 0.45783[/tex]

when made into a percentage that is 46%

Now we can find the percentage of those cars that are 20+ years old by dividing the number of 20+ year old cars by our percentage

use?
First brand:
milliliters
х
?
Second brand:
milliliters

Answers

Answer:

You want to set up an equation that will match the word problem. Let's call the amount of the first brand, F, and the amount of the second brand, S.

We want the total mixture to be 310mL so: F + S = 310

Also, you want the total mixture to contain 8% vinegar so: .06F + .11S = .08(310)

Now, we can solve the system of equations using substitution.

F + S = 310

.06F + .11S = .08(310)

F = 310 - S      [solve 1st equation for F]

.06(310 - S) + .11S = .08(310)     [substitute into 2nd equation]

18.6 -.06S +.11S = 24.8

.05S = 6.2

S = 124

F + 124 = 310     [substitute answer for S back into original equation]

F = 186

Answer: To make a 310mL mixture that contains 8% vinegar, use 186mL of the first brand and 124mL of the second brand.

[tex]4(7)-4(14-7)=24[/tex] [tex]28-4(7)=24[/tex] [tex]28-28=24[/tex] [tex]0\neq 24[/tex]

B:

Therefore, B is the correct answer.

Melissa walks 3 miles to the house of a friend and returns home on a bike. She averages 4 miles per hour faster when cycling than when walking. The total time for the round trip is 2 hours. Find her speed walking and biking. Set up an equation and solve

SHOW WORK PLS!!

Answers

Answer: Melissa's walking speed is 2mph. Her biking speed is 6mph

Step-by-step explanation:

Her total distance is 6 miles, because she walks 3 miles, and so the returning distance must also be 3.

Let her cycling speed (in mph) be x

Let her walking speed (in mph) be y

We know that x = y + 4

Since we know that S = D/T:

T = D/S

So her cycling time must be: T = 3/x

and her walking time must be: T = 3/y

since we know that x = y + 4, we can substitute this into her cycling time, and rewrite it as T = 3/y+4

we also know that 3/y+4 + 3/y = 2, because the problem says that the total time taken was 2 hours.

We simply need to solve this equation now:

3/y+4 + 3/y = 2

The LCD for y+4 and y is y² + 4y

so now we have:

(3y/y² + 4y) + (3y+12/y² + 4y) = 2

(6y + 12)/y² + 4y = 2

6y + 12 = 2y² + 8y

2y² + 2y - 12 = 0

Solve this using factoring:

2y² + 2y - 12 = 0

2(y² + y - 6) = 0

(y+3)(y-2) = 0

using ab = 0, then a or b =0:

y = -3, or y = 2

Since speed cannot be negative, our answer is 2 for y. So y, or the walking speed is 2mph. Since x = y + 4, we know that x = 6 mph

Melissa's walking speed is 2mph. Her biking speed is 6mph

Answer:

y = - (x - 2)² + 10

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square

y = - x² + 4x + 6 ( factor out - 1 from the first 2 terms )

y = - (x² - 4x) + 6

To complete the square

add/subtract ( half the coefficient of the x- term )² to x² - 4x

y = - (x² + 2(- 2) + 4 - 4) + 6

y = - (x - 2)² + 4 + 6

y = - (x - 2)² + 10 ← in vertex form
