Answer:

m = $\frac{17}{4}$

Step-by-step explanation:

Cross multiply.

$\frac{8}{5} =\frac{2}{m-3}$

8(m-3)=10

8m-24=10

8m=34

m=34/8

Simplify.

m= 17/4

An exponential function has a starting value of 13 and a growth rate of 0.78%. Write an equation to model the situation.

Elina [12.6K]

Answer:

The equation that models the situation is $A(t) = 13(1.0078)^t$

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

$A(t) = A(0)(1+r)^t$

In which A(0) is the starting value and r is the growth rate, as a decimal.

Starting value of 13 and a growth rate of 0.78%.

This means that $A(0) = 13, r = 0.0078$

Write an equation to model the situation.

$A(t) = A(0)(1+r)^t$

$A(t) = 13(1+0.0078)^t$

$A(t) = 13(1.0078)^t$

The equation that models the situation is $A(t) = 13(1.0078)^t$

At Clint's next birthday, he will he will be twice the age of his cousin Elizabeth. Elizabeth is now two thirds the age of he br

tigry1 [53]

Ken:

Ken's Age = 18

Elizabeth:

Elizabeth's Age = 2/3 x Ken's age

Elizabeth's Age = 2/3 x 18

Elizabeth's Age = 12

Clint:

-Note: At Clint's <em>next</em> birthday. So we need to subtract 1 from the age.

Clint's Age = (2 x Elizabeth's Age) - 1

Clint's Age = (2 x 12) - 1

Clint's Age = 24 - 1

Clint's Age = 23 right now

Hope this helps!! :)
