Answer:
B. (x+1)^2 + (y-7)^2=196
Step-by-step explanation:
The equation is (x-h)^2 + (y-k)^2=r^2
h=-1,k=7 and r=14
(x-(-1))^2 + (y-7)^2= 14^2
(x+1)^2 + (y-7)^2 = 196
Answer:
A) 150 m
B) 180.28 m
Step-by-step explanation:
A) In order to find the horizontal distance from the base of the cliff to the speed boat, use the Pythagorean theorem to calculate the length of the missing side.
We are told that one of the sides is 80 m and the hypotenuse is 170 m. Therefore,
- a² + b² = c²
- (80)² + b² = (170)²
- b² = 170² - 80²
- b² = 22500
- b = 150
The horizontal distance between the base of the cliff and the boat is 150 m.
B) Now, the side that was 80 m is now 100 m (includes the height that the helicopter is above Jumbo). The horizontal distance remains the same, 150 m, but the hypotenuse is different. Solving for the hypotenuse will give us the distance between the helicopter and the speed boat.
- (100)² + (150)² = c²
- 32500 = c²
- 180.28 = c
The distance between the helicopter and the speed boat is 180.28 m.
Answer:
D. A news organization that is not owned by a corporation.
Step-by-step explanation:
Answer:
171.2 inches
Step-by-step explanation:
7% is equaled to 0.07 and multiplied by 160 equals 11.2 then I added that to 160 to get 171.2 inches. I hope im correct.
When given a graph, the easiest way to find the slope is to count the rise over run (y/x).
The slope from x=0 to x=2 is: 3 up over 2 right = +3/+2 = 3/2 = 1.5
The slope from x=2 to x=∞ is: 1 up over 2 right = +1/+2 = 1/2 = 0.5
Answer: C. <em>0.5</em>
