A company that manufacturers deep freezers has developed a new formula of refrigerant, the substance used to cause cooling in re

frigerators and freezers. To determine if freezers using the new formula of refrigerant are more efficient than those using the company's original formula, they conducted an experiment with two identical freezers. The first freezer was cooled using the new formula, and the second freezer was cooled using the original formula. A gallon of water was placed in each freezer, and they measured the time required for the water to turn to ice. Match the terms with the correct descriptions in the context of this scenario.

A ball is thrown into the air. The height in feet of the ball can be modeled by the equation, h(t) = −16t2 + 10t + 6 where t is
Lelechka [254]

A function assigns the value of each element of one set to the other specific element of another set. The correct option is D.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The time at which the ball will hit the ground is,

h(t) = −16t² + 10t + 6

0 = -16t² + 10t + 6

8t² - 8t + 3t - 3= 0

8t(t-1)+3(t-1) = 0

(8t+3)(t-1)=0

t = -0.375, 1

Hence, the ball hit the ground at 1 second, while the function in intercept form can be written as h(t) = (−8t − 3)(2t − 2).

Thus, the correct option is D.

A map of the park can be divided into a grid of 9^2 equal sections of land. It is estimated that there are 9^6 ants per section
kenny6666 [7]

Answer:

9^8

Step-by-step explanation:

The total number of ants is

(total number of sections)(ants in each section).

let x be the total number of ants.

Substitute the given values.

x = (9^2)(9^6)

x = 9^(2+6)  <= exponent rule: when multiplying exponents with the same base, add the exponents.

x = 9^8
