Given the following exponential function, identify whether the change represents

1 answer:

4 0

The answer is exponential decay and the percent decrease is 93% if the number in parentheses is below 1 or has a decimal with a 0 in the ones place it’s decay then you multiply the number by 100 and get the percent hope this helps

A $59 sweater is on sale for $40. what percent decrease is this?

wariber [46]

Answer:

32.2033898 % decrease

Step-by-step explanation:

To find the percent decrease, take the original amount and subtract the new amount

59-40 = 19

Divide by the original amount

19/59 =.322033898

Change to a percent

32.2033898 % decrease

A player rolls a pair of standard dice. Find the probability P(sum is at least 3)

Nezavi [6.7K]

D because there are 6 sides to a dice and there are 3 options where the number is bigger than 3. Therefore 3/6 = 15/30

noelle is drawing fraction bars to model the sum of 1/5 and 3/4. What is the smallest number of equally sized pieces each fracti

Bess [88]

Answer:

the smallest number of equally sized pieces is 20

Step-by-step explanation:

The computation of the smallest number of equally sized pieces is as follows:

Given that

The sum of 1 by 5 and 3/4

Now

if we sum it

= 1 ÷ 5 + 3 ÷ 4

= 4 + 15 ÷ 20

= 19 ÷ 20

Now as if we do the lcm so the denominator sum be 20

Therefore the smallest number of equally sized pieces is 20

What is the rate of change and initial value for the linear relation that includes the points shown in the table?

defon

The initial value: 25, rate of change: -5 ⇒ answer C

Step-by-step explanation:

The table:

→ x : 1 : 3 : 5 : 7

→ y : 20 : 10 : 0 : -10

The linear relation between x and y is y = m x + b, where

m is the rate of change
b is the initial value

Let us use the table to find m and b

∵ $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ , where $(x_{1},y_{1})$

and $(x_{2},y_{2})$ are any two ordered pairs in the table

∵ $(x_{1},y_{1})$ = (1 , 20)

∵ $(x_{2},y_{2})$ = (3 , 10)

∴ $m=\frac{10-20}{3-1}=\frac{-10}{2}=-5$

∵ m is the rate of change

∴ The rate of change is -5

Substitute the value of m in the form of the linear relation

∴ y = -5 x + b

To find b substitute x and y in the equation by the coordinates of any points in the table, let us chose point (5 , 0)

∵ x = 5 and y = 0

∴ 0 = -5(5) + b

∴ 0 = -25 + b

- Add 25 to both sides

∴ 25 = b

∵ b represents the initial value

∴ The initial value is 25

The initial value: 25, rate of change: -5
