Answer:
The center is ( 5.3, -3.3) and 7 is the radius
Step-by-step explanation:
We can write the equation of a circle as
( x-h)^2 + ( y-k)^2 = r^2
Where ( h,k) is the center and r is the radius
(x - 5.3)^2 + (y + 3.3)^2=49
(x - 5.3)^2 + (y - -3.3)^2=7^2
The center is ( 5.3, -3.3) and 7 is the radius
The horizontal component of the velocity of the shot is 35 cos 40 ft/sec which is constant
Therefore:-
Velocity = distance / time
35 cos 40 = 40 / t
t = = 40 / 35cos40 = 1.49 seconds to nearest hundredth
A hanger stays balanced when the weights on both sides are equal.
An equation can be compared to a balanced hanger. We can change the equation, but for a true equation to remain true, the same thing must be done to both sides of the equal sign.
3x + 6 < 4.5 => -0.5
Answer is -10.
x-intercept, y=0, substitute for y in the equation. you will have -2x+5(0)=20
-2x =20
x =20/-2
x=-10
