It took James 1 3/4hrs to
travel a distance of 126
in his car. Calculate his speed

Assuming that 126 is expressed in miles (mi), the answer is 72 miles per hour.

Step-by-step explanation:

Speed is calculated using the following formula: distance/time.

Knowing that he travels 126 miles in 1 hour and 45 minutes, we obtain 126 miles divided by 1.75 = 72 mph.

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3

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
