Answer:
Step-by-step explanation:
a = b
Pythagorean Theorem:
b = 10/√2
Answer:
B. Exponential
Step-by-step explanation:
The annual wolf population in each year is
w = 500 500(0.9) 500(0.9)² 500(0.9)³ …
n = 1 2 3 4 …
The model is w = 500(0.9)ⁿ⁻¹.
This is an exponential model, because the independent variable is in an exponent.
For this case we have the following kinematic equation that models the problem:
h (t) = (1/2) * (- 9.8) * t ^ 2 + 12 * t + 2
Rewriting we have:
h (t) = -4.9 * t ^ 2 + 12 * t + 2
When the ball hits the ground we have:
-4.9 * t ^ 2 + 12 * t + 2 = 0
Solving the polynomial we have:
t1 = -0.16
t2 = 2.61
We ignore the negative root because it is time.
Answer:
It will take the ball to hit the ground about:
t = 2.61 sec
Answer:
y = -3/5 x +3
Step-by-step explanation:
3x + 5y = 15
Subtract 3x from each side
-3x+3x + 5y = -3x+15
5y = -3x+15
Divide each side by 5
5y/5 = -3x/5 +15/5
y = -3/5 x +3
