The ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.
<u>Explanation:</u>
We need to find the time at which the ball will be at height 19 feet.
Equation:
h = 3 + 34t - 16t²
19 = 3 + 34t - 16t²
16 = -16t² + 34t
-16t² + 34t - 16 = 0
On solving the equation, we get
t1 = 0.7 s and t2 = 1.42s
Therefore, the ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.
Answer: 12
Step-by-step explanation:
12 times 12 is 144 so 12.in each row
Dude, it's impossible to solve without the pic
Answer:
F , D, A
Step-by-step explanation:
As we know vertical stretch of f(x) happens when we chane the value of the patameter a in this general form:
y = a. f(k(x-d))+ c
when |a| > 1 because When |a| > 1 (when a is greater than 1), the function is stretched vertically by a dilation factor of |a|.
So we choose, F , D, A
