Rewrite the function to determine whether it represents exponential growth or exponential decay. Identify the percent rate of change. Round numbers to the nearest hundredth, if necessary. y=(1.06)8t In the form y=a(1+r)t, the function is y≈ . To the nearest percent, the rate of change is a %.

y ≈1*(1+0.59)^t. The rate of change is = 59%

Step-by-step explanation:

We have t mulitplied by 8 in the expression of y. We can write that power with a power of powers, using the property

Therefore,

If we replace a with 1.06, we obtain

Thus, y ≈1*(1+0.59)^t. The rate of change is ln(1.59) * 1.59^t. After 1 unit of time t, the rate of change is 0.59*100 = 59%

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man

step-by-step explanation:

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
