Answer:

19 skins

Step-by-step explanation:

Total surface area of the cone = πr(r+l)

r is the radius = 10ft/2 = 5ft

l is the slant height

l^2 = 12^2 + 5^2

l^2 = 144+25

l^2 = 169

l = 13ft

Get the surface area

TSA = 3.14(5)(5+13)

TSA = 15.7*18

TSA = 282.6 ft^2

If each skin covers 15 sq. feet

Number of skin needed = 282.6 /15

Number of skin needed = 18.84

Number of skin needed is approximately 19 skins

arsen [322]

Answer: $525

Step-by-step explanation:

The formula for Simple interest is calculated as PRT where

P = Principal = $7500

R = Rate = 3.5%

T = Time = 2 years

Interest = PRT

= 7500 × 3.5% × 2

= 7500 × 0.035 × 2

= $525

Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height above ocean measured in f
lbvjy [14]

Answer:

480 feet.

Step-by-step explanation:

We are told that the function h(t)=-16t^2+16t+480 models Jason's height above ocean measured in feet as a function of time and t is the time in seconds from jumping off.

To find the height of cliff we need to substitute t=0 in our given function as at t=0 we will get Jason's height above ocean which is same as the height of the cliff.

Upon substituting t=0 in our function we will get,

h(0)=-16(0)^2+16*0+480

h(0)=-0+0+480

h(0)=480

Since, the function gives Jason's height above ocean in feet, therefore, the cliff was 480 feet high.
