Answer:

the base of the ramp is 31 inches long.

Step-by-step explanation:

c = a/sin(α)

= 33.48514

b = √c2 - a2

= √33.4851373155042 - 122

= √977.25442103816

= 31.26107

How high is the building (ie. from what height was the potato launched) if h=-2(t-3)2+32
Llana [10]

Answer:

14

Step-by-step explanation:

To find the height from which the potato was launched, you need to set the time to 0 (since that is at the beginning). Plugging this into the equation, you get:

h=-2(0-3)^2+32

h=-2(9)+32

h=32-18

h=14

Hope this helps!

Cassidy's goal is to raise more than $75 for charity. She has already raised $6. Now she is selling cupcakes for $3 each to reac
hodyreva [135]
$75= Cassidy's goal
c= number of cupcakes
a= $6 already raised

EQUATION:
75<$3c + a
substitute $6 in for a

75< $3c + 6
subtract 6 from both sides

69<3c
divide both sides by 3

23<c

Cassidy needs to sell at least 23 cupcakes to reach her goal of $75.


Answer:

FALSE: Cassidy will need to sell any number of cupcakes greater than 12 to reach her goal.

TRUE: Cassidy will need to sell any number of cupcakes greater than 23 to reach her goal.


Hope this helps!  :)
