I think the answer is x equals 21
Answer:
hmax = 628 ft
Step-by-step explanation:
The bullet will reach its maximum height when its velocity h'(t) becomes zero. The equation of motion is
h(t) = -16t^2 + 200t + 3
Taking the derivative of h(t) is
h'(t) = -32t + 200
Solving for t when h'(t) = 0, we get
t = 200/32 = 6.25 s
and this is the time it takes for the bullet to reach its maximum height. Using this value for t into h(t), we get
h = -16(6.25 s)^2 + 200(6.25 s) + 3
= 628 ft
Answer:
The three angles are 84º, 30º, and 66º. You multiply the ratio 14:5:11 by 6º.
Step-by-step explanation:
The sum of a triangle's interior angles is 180º. From the information we know:
- 14xº+5xº+11xº=180º
- Combine like terms, 30xº=180º
- Divide, xº=6º
Now we can say that the three angles are 14(6)=84º, 5(6)=30º, 11(6)=66º.
1 + -3 1/2 is = to -2.5 so v= -2.5
