Answer:

B

Step-by-step explanation:

Answer:

Option (D)

Step-by-step explanation:

Formula to get the average rate of change of the function f(x) between two points x = a and b is,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

We have to calculate the average rate of change between x = 0 and x = 2.

From the graph attached,

f(0) = -2

f(2) = 6

Therefore, average rate of change = [tex]\frac{6-(-2)}{2-0}[/tex]

                                                          = [tex]\frac{8}{2}[/tex]

                                                          = 4

Option (D) will be the correct option.

Answer:

19)  ( [tex]\frac{-2}{5}[/tex])^2 = [tex]\frac{4}{25}[/tex]

20) -[tex]9^{2}[/tex] = -81

21)  [tex]2^{4}[/tex] = 16

Step-by-step explanation:

The only wrong ones are

19)  ( [tex]\frac{-2}{5}[/tex])^2 = [tex]\frac{4}{25}[/tex]

20) -[tex]9^{2}[/tex] = -81 ... negative is not inside a parenthesis that's why it is still negative

21) you can add another way is [tex]2^{4}[/tex] = 16

Everything else looks good.  Great job!

The value of the phone after 2 years will be equal to $388.8.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also represent the logical syntax's operation order and other properties.

Given that the cell phone costs $750 and loses 28% of its value each year. The value of the phone after 2 years will be,

The value of the phone after 2 years will be calculated as,

Cost of phone = 750 x ( 0.28 )²

Cost of the phone = $388.8

Answer:

x = -9/2  or -4.5

Step-by-step explanation:

-2x-5=4

Add 5 to each side

-2x-5+5=4+5

-2x = 9

Divide each side by -2

-2x/-2 = 9/-2

x = -9/2  or -4.5

$760 earned in intrest

$10260 new account balance

Step-by-step explanation:

First we have to find 4% of 9500

use the formuala

[tex]\frac{4}{100} =\frac{x}{9500}[/tex]

4×9500=38000

38000÷100=380

now 380×2=760

add 760 to 9500 for new account balance

Answer: $7.50

Step-by-step explanation: they spent 15 n if they split that it’s 7.50

Answer:

Step-by-step explanation:

Step one:

we are told that their joint amount is $62

let John's amount be x

and Pedro's amount be y

so that y=x+15

Step two:

The equation to represent the situation is

62=x+(x+15)

open the bracket and solve for x we have

62=x+x+15

62=2x+15

2x=62-15

2x=47

divide both sides by 2

x=47/2

x=23.5

John has $23.5

Answer:

0.22 miles

Step-by-step explanation:

Let

A = Distance pumpkin A travels = 0.61 miles

Distance pumpkin B travels is 0.28 mile farther than Pumpkin A

[tex]B=0.28+A\\\Rightarrow B=0.28+0.61\\\Rightarrow B=0.89\ \text{miles}[/tex]

Distance pumpkin B travels is 0.06 miles further than pumpkin C

[tex]B=0.06+C\\\Rightarrow C=B-0.06\\\Rightarrow C=0.89-0.06\\\Rightarrow C=0.83\ \text{miles}[/tex]

To calculate how much farther pumpkin C travels than pumpkin A we have the subtract their distances

[tex]C-A=0.83-0.61=0.22\ \text{miles}[/tex]

So, pumpkin C traveled 0.22 miles more than pumpkin A.
