Answer:
Step-by-step explanation:
If RS is the diameter of the circle, then the midpoint of RS will be the center of the circle.
Equation of a circle:
(where (h, k) is the center and r is the radius)
Substituting found center (-2, 2) into the equation of a circle:
To find , simply substitute one of the points into the equation and solve:
Therefore, the equation of the circle is:
Answer:
F(x) = 3
Step-by-step explanation:
Just substitute x with 1 and you add it with 2 and your answer is three
Answer:
Step-by-step explanation:Since we want to know how much time elapsed since the object was launched until it ht the ground. At the ground, the height is 0.
Therefore the equation h(t) = 80t – 16t2 becomes 0= 80t – 16t2
Solving the equation for t gives 80t =16t2 or 16t=80 or t=5sec
The object hits the ground 5 seconds after it is launched.
I would say the best estimate would be 9 because the real answer is 8.71 and if you round that to the 1 place the answer would be 9.
14(8-W)=0
(14*8)-(14*W)=0
112-14W=0
-112 -112
------------------- The answer is 8
-14W= -112
-14W/(-14)= -112/(-14)
W=8
