-1/10 - (-2/10) equals what?

Answers

Answer 1

Answer: -1/10 -(-2/10)
= -1/10 +2/10
= (-1+ 2)/10
= 1/10
= 0.1

-1/10- (-2/10)= 0.1~

The horsepower , H(s), required for a racecar to overcome wind resistance is given by the function : H(s) = 0.003s^2+0.07s-0.027 , where (s) is the speed of the car in miles per hours. What is the average rate of change in horsepower per unit speed if the race car increases in speed from 80 mph to 100 mph . A 1.64 B. 0.61 C. 12.2 D. 20.0

Answers

The average rate of change in horsepower per unit speed if the race car increases in speed from 80 mph to 100 mph is 0.61

The function of the horsepower is given as:

$\mathbf{H(s) = 0.003s^2 + 0.07s - 0.027}$

The average rate of change is calculated using:

$\mathbf{A(s) =(H(b) - H(a))/(b - a)}$

Substitute 80 and 100 for a and b, respectively

$\mathbf{A(s) =(H(100) - H(80))/(100 - 80)}$

$\mathbf{A(s) =(H(100) - H(80))/(20)}$

Calculate H(100) and H(80)

$\mathbf{H(80) =0.003 * 80^2 + 0.07 * 80 - 0.027 = 24.773}$

$\mathbf{H(100) =0.003 * 100^2 + 0.07 * 100 - 0.027 = 36.973}$

So, we have:

$\mathbf{A(s) =(H(100) - H(80))/(20)}$

$\mathbf{A(s) = (36.973 - 24.773)/(20)}$

$\mathbf{A(s) = (12.2)/(20)}$

$\mathbf{A(s) = 0.61}$

Hence, the average rate of change in horsepower per unit speed is 0.61

Average rate of change = [H(100) - H(80)] / (100 - 80)
H(100) = 0.003(100)^2 + 0.07(100) - 0.027 = 0.003(10000) + 0.07(100) - 0.027 = 30 + 7 - 0.027 = 36.973

H(80) = 0.003(80)^2 + 0.07(80) - 0.027 = 0.003(6400) + 0.07(80) - 0.027 = 19.2 + 5.6 - 0.027 = 24.773

Average rate of change = (36.973 - 24.773)/(100 - 80) = 12.2/20 = 0.61

A volunteer has 12 pounds of birdseed to put in bird feeders in all of the city park. There are 3 and one four cups of birdseed on a pound, and each bird feeder holds about 3 four cups of birdseed. How many bird feeder can the volunteer fill completely?

Answers

How many bird feeders can the volunteer fill completely?

I will guess that each feeder holds 4 cups of seed.

12 pounds times 3 and 1/4 cups per pound = 39 cups available.

39 cups divided by 4 cups per feeder = 9.75

The volunteer can fill 9 feeders completely,

1. What is the length of the segment joining the points at (-1,6) and (-5,3) 2. What is the length of the segment joining the points at (-4, 1) and (3,7)

Answers

QUESTION 1

We want to find the length of the segment joining the points at (-1,6) and (-5,3).

We use the distance formula which is given by the formula,

$d=√((x_2-x_1)^2+(y_2-y_1)^2)$

$d=√(( - 5 - - 1)^2+(3 - 6))^2)$

$d=√(( - 5 + 1)^2+(3 - 6)^2)$

$d=√(( - 4)^2+( - 3)^2)$

$d=√(16+9)$

$d=√(25)$

$d = 5 \: units$

QUESTION 2

We want to find the length of the segment joining at (-4,1) and (3,7).

We use the distance formula to get,

$d = \sqrt{(3 - - 4)^(2) + {(7 - 1)}^(2) }$

$d = \sqrt{(3 + 4)^(2) + {(7 - 1)}^(2) }$

$d = \sqrt{7^(2) + {6}^(2) }$

$d = √(49+ 36 ) .$

$d = √(85 ) \: units$
