Answer:

The initial value is 1 and growth factor as a percentage will be 710%.

Step-by-step explanation:

The exponential growth function is given by f(x) = a (b)^{x} ......... (1), where, a is called as the initial value and b is called as the growth factor.

Now, in this case the the function is given to be  h(t) = 8.1^{t} ....... (2)

Now, comparing equation (1) and (2), we get

a = 1 and b = 8.1

Now, b = 1 + r

⇒ 8.1 = 1 + r

⇒ r = 7.1

So, the initial value is 1 and growth factor as a percentage will be 7.1 × 100 % = 710%. (Answer)

postnew [5]

Answer:

10 and 16, x+(x+6)=26

Step-by-step explanation:

Michelle has an age we don't know, so we put her age as x.

Yogi is 6 years older than her, so her age is x+6

Michelle=x

Yogi=x+6

we know both their ages equal 26. so we set it up as

x+(x+6)=26

combining like terms we get

2x+6=26

subtract 6 from both sides

2x=20

divide both sides by 2

x=10

now that we have the value for x, we plug it into their original ages

Michelle is 10, because her age is just x.

Yogi is 16, because her age is x+6
