Answer:

h(0) = –16t^2 + 32t + 48

Cindy is a waitress and makes $36 per night. Since this is a particularly low amount
PIT_PIT [208]

Answer:

8 tables

Step-by-step explanation:

since she makes on average $18 per table and wants to make $180 we can just multiply $18 by 10 tables however we have to take into account the $36 she makes per night. 36 is just 18 multiplied by 2 meaning we can subtract a total of 2 tables away from the total of 10 tables to get 8 tables

A coat of paint of thickness 0.06 cm is to be applied uniformly to the faces of a cube of edge 33 cm. Use differentials to find
Aneli [31]

Answer:

392 cm^3

Step-by-step explanation:

Let X represent the edge of a cube

let t represent the thickness of the paint.

Volume of a cube = x^3

V = x^3

Differentiate V with respect to x

dV/dx = 3x^2

dV = 3x^2 dx

dx = 2dt

= 2(0.06)

= 0.12

dV = 3(33)^2 (0.12)

dV = 392.04cm^3

dV = 392 cm^3

A disc is thrown into the air with an upward velocity of 20 ft/sec. Its height h in feet after t seconds is given by the functio
labwork [276]

Answer:

Time t = 1.39 seconds

Step-by-step explanation:

Given;

Initial velocity v = 20 ft/sec

height equation;

h = -16t^2 + 20t + 6

How long does it take for the disc to be caught 3 feet off the ground;

At this point h = 3

Substituting h = 3 into the height equation;

3 = -16t^2 + 20t + 6

-16t^2 + 20t + 6 - 3 = 0

-16t^2 + 20t + 3 = 0

Solving the quadratic equation;

t = 1.39 or t = -0.14

Since t cannot be negative;

Time t = 1.39 seconds

the windows on a building are proportional to the size of the building. the height of each is 18in and the width is 11in if the
Elena-2011 [213]
You can set this up as 2 fractions equal to each other, like ratios.

18/11=108/x

Cross multiply and you get 18x=1,188

Now divide both sides by 18 and get x.

x=66.

If the height of the building is 108ft, the width is 66ft.
