Answer:
2s or 3s
Step-by-step explanation:
Given the function that models the height of the object as;
h(t) = - 16t^2 + 80t + 96
The ball reaches the ground when h = 0
Substitute
0 = - 16t^2 + 80t + 96
Divide through by -16
0 = t²-5t-6
t²-5t-6 = 0
t²-2t-3t+6 = 0
t(t-2)-3(t-2) = 0
(tt-2)(t-3) = 0
t - 2 = 0 and t-3 = 0
t = 2 and 3s
Hence it will take the ball 2s or 3s to reach the ground
Answer: x= -3
Step By Step Explanation:
The equation given in the question has one unknown variable and so the value of k can definitely be found.
4/9(k + 4/7) = 3 1/3
4/9[(7k + 4)] = 10/3
4/(63k + 36) = 10/3
4 * 3 = 10 * (63k + 36)
12 = 630k + 360
12 - 360 = 630k
- 348 = 630k
Reversing both sides we get
630k = - 348
k = - 348/630
= - 174/315
= - 58/105
So the value of K comes out to be - 58/105 and it is not possible to simplify it further.
Answer:
Your answer should be A) 0.34.
Step-by-step explanation:
Look at the other 3 triangle above and compare it to the below triangle that only has 70°.
One of the triangles is similar to the triangle below that has 70°.
Using the Side Length value we get 3.4/10 = 0.34.
Answer:
a1 = .45 and r = 8
Step-by-step explanation:
This is of the form
sum a1 r^ k-1
a1 = .45 and r = 8
