Find the total value
68 pieces of $1 = $68

Find the number of $5 notes he can exchange
68 ÷ 5 = 13 Remainder 3
So he got 13 $5 notes and the remaining 3 in one dollar notes.

You are tossing an apple. After t seconds, the height of the apple in feet is given by h = -16t2 + 38.4t + 0.96. What is the dom
Nesterboy [21]

Using function concepts, it is found that the domain is 0 ≤ t ≤ 2.4, given by option C.

----------------------

The height of the apple after t seconds is given by:

h(t) = -16t^2 + 38.4t + 0.96

  • The domain of a function is the <u>set that contains all possible input values.</u>
  • The possible input values for this situation are the values of t between 0 and the instant in which the apple hits the ground, which is t for which h(t) = 0.

----------------------

h(t) = -16t^2 + 38.4t + 0.96

Which is a quadratic equation with a = -16, b = 38.4, c = 0.96

To find the solutions:

\Delta = b^2 - 4ac = (38.4)^2 - 4(-16)(0.96) = 1536

t_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{-38.4 + \sqrt{1536}}{2(-16)} = -0.0247

t_2 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{-38.4 - \sqrt{1536}}{2(-16)} = 2.4

The apple is in the air for 0 ≤ t ≤ 2.4, which means that the domain is given by option C.

What mixed number is 3/8 of 100
shusha [124]
3/8 0f 100
100 / 8 = 12.5
Now, let's multiply this by 3 to be able to get the value
=> 12.5 * 3 = 37.5 is the value of 3/8 of 100.
This is a mixed number because its a combination of whole and decimal numbers.

Find the circumference of the pizza to the nearest tenth. Pizza : 10 inches
Eddi Din [679]

Answer:

31.4 in

Step-by-step explanation:

I must assume that you meant "10-inch pizza," which implies a diameter of 10 inches.  The formula for the circumference of a circle when the diameter is known is C = πd , so here:

C = π(10 in) = 10π in, or roughly 31.4 in.
