K (t) = 13t - 2; k(3)

Mathematics
1 answer:
True [87]3 years ago
4 0

Answer:

k(3)=37

Step-by-step explanation:

This questions asks us to find k(3).

We want to find what k(t), or y is, when t, or x is equal to 3.

k(t)=13t -2

Therefore, we can substitute 3 in for t.

k(3)= 13(3)-2

Solve according to PEMDAS ( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

First, multiply 13 and 3

k(3)=39-2

Subtract 2 from 39

k(3)=37

Kurt drives a total of 32 miles to and from work every day. He works 5 days a week. How many miles does Kurt drive in a week for
Naily [24]
Does Kurt drive 32 miles to work and 32 back home or does Kurt drive a combined total of 32 miles to and from work.

If he drive 32 miles to work and 32 home- Kurt would have driven a total of 64 miles each day. So if he works 5 days a week you would just use this simple equation: {64 x 5} which would get you 320 miles each week.

If he drives a combined total of 32 miles each day then you use this following equation: {32 x 5} which would get you 160 miles each week

If you know please help me
MrRa [10]

Average rate of change of the function =\frac{75}{2}

Solution:

Given function: f(x)=5(2)^{x} from x = 1 to x = 5

Substitute x = 1 and x = 5 in f(x).

f(1)=5(2)^{1}=10

f(5)=5(2)^{5}=160

Let us find the average rate of change of the function.

Average rate of change

                      $=\frac{f(b)-f(a)}{b-a}

Here a = 1 and b = 5.

                     $=\frac{f(5)-f(1)}{5-1}

Substitute f(5) and f(1).

                     $=\frac{160-10}{4}

                     $=\frac{150}{4}

                     $=\frac{75}{2}

Average rate of change of the function =\frac{75}{2}

What is the surface area of the right prism?
Mama L [17]
2 surfaces are 6 in by 9 in, meaning that their combined area is 2(54 in^2).
2 surfaces are 6 in by 18 in; combined area is 2(108 in^2).
2 surfaces are 9 in by 18 in; combined area is 2(162 in^2).

Add up these areas:  A = 2(54+108+162) in^2 = 648 in^2 (answer)
