Answer:
24
Step-by-step explanation:
Therefore our proportion is: (where x is the "vertical" rise)
Slope is defined as rise over fun so....
12/100 = x/200
(12*200)/100 = x
24 feet = x

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 8x² + 5x - 2
x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 8(-2)² + 5(-2) - 2
- Exponents: f(-2) = 8(4) + 5(-2) - 2
- Multiply: f(-2) = 32 - 10 - 2
- Subtract: f(-2) = 22 - 2
- Subtract: f(-2) = 20
Answer:
88/7 ft = 12.6 ft (nearest tenth)
Step-by-step explanation:
Circumference of a circle = 2r
<u>Radius of inner circle</u>
Given:
- circumference of inner circle = 22ft
- = 22/7
⇒ 22 = 2 x (22/7) x r
⇒ r = 3.5
So the radius of the inner circle is 3.5 ft
<u>Radius of outer circle</u>
If the distance between the inner circle and the outer circle is 2 ft, then the radius of the outer circle = 3.5 + 2 = 5.5
<u>Circumference of outer circle</u>
Therefore, circumference of outer circle:
= 2 x (22/7) x 5.5
= 242/7 ft
<u>Difference between circumferences</u>
Difference = outer circle circumference - inner circle circumference
= 242/7 - 22
= 88/7 ft
= 12.6 ft (nearest tenth)
Answer:
(0,5)
Step-by-step explanation:
We add 2 to the x and 1 to the y because the total difference is 6 and 3 respectively and we must divide by 3
