If you divide the age by the height the quotient is 3.57 in each case so it is direct variation
C is correct
Answer:
D. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp
Step-by-step explanation:
f(x) = x²- 10x + 25
We can factor this.
What 2 numbers multiply to 25 and add to -10
-5 *-5 = 25
-5+-5 = -10
f(x) =(x-5) (x-5)
Using the zero product property, we know that it will cross the axis at x=5
At 5 seconds f(x) =0. This means the height is zero at 5 seconds
We have a line tangent to the circle with center B at point C. We know that the angle formed between the tangent line at the point of intersection to the line extended from that point to the center of the circle is equal to 90°. In the problem, the 90° is for ∠BCA. We also know that the summation of all angles in a triangle is 180°. We have the solution below for the ∠BAC
180°=∠BAC + ∠BCA + ∠ABC
180°=∠BAC + 90° + 40°
∠BAC =50°
The answer is 50°.
50.952 miles per hour
for an approximate result, divide the speed value by 1.609
