Please answer 27 and 28

27: 29.93 Seconds

28: 28 ° Fahrenheit

Step-by-step explanation:

Number #27:

Given:

#1 Lap = 14.76 seconds

#2 Lap = 15.17 seconds

Steps:

1. Use the algorithm method.

      1

14.76

+ 15.17

29.93 seconds  

Number #28:

Given:

Wind Chill Temperature: - 18 ° F

Actual Temperature: 10 ° F

Steps:

1. Subtract 18 from 10.

- 28 ° degrees fahrenheit

Note: Whenever there is a negative sign next to a temperature, it means it's below freezing as the below freezing temperature is 0  ° Fahrenheit. This also means subtraction. In this case, you would subtract the negative amount from the positive amount creating an equation, that equation represents the degrees in fahrenheit:

10 - 18

The result should be -28.

This also means that the difference between both temperatures is 28 degrees. Wind chill creates a feeling of higher temperatures even though the actual temperature in the atmosphere was 10 ° F in this specific land structure.

Hope this helps,

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
