Color Pencil Price per Pencil

2 answers:

5 0

First, add up all the prices.

3.50 + 1.25 + .76 = 5.51

I tested a few numbers and I discovered that Mike bought 37 pencils.

5.51 * 37 = 203.87

What you can do is trial and error. I started going multiplying each price by 10s and when I started multiplying by 30s I got a total of 37 colored pencils

A dolphin jumps from the water at an initial velocity of 16 feet per second. The equation h + -16t^2 + 80t models the dolphin's

Dominik [7]

Answer:

100feet

Step-by-step explanation:

Given the height reached by a dolphin expressed by the equation is h = -16t^2 + 80t. At maximum height, the velocity is zero, hence;

v(t) = dh/dt = -32t + 80

0 = -32t + 80

32t = 80

t = 80/32

t = 2.5secs

Substitute t = 2.5 into the height formula h = -16t^2 + 80t

h = -16(2.5)^2 + 80(2.5)

h = -100+200

h = 100feet

Hence the maximum height the dolphin jumps is 100feet
