Answer:
Therefore,
Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.
Step-by-step explanation:
Given:
The wind speed near the center of a tornado is represented by the equation,
Where,
d = the distance, in miles
S = the wind speed, in miles per hour.
To Find:
S = ? at d = 4 miles
Solution:
We have
.........Given
Substitute d = 4 in above equation we get,
Rounding the answer to the nearest tenth we have
Therefore,
Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.
Answer:
(4, -128).
Step-by-step explanation:
If the function is written in the form y = a(x – h)^2 + k, the vertex will be (h, k). Let's write the function 8x^2 - 64x in the form of a(x – h)^2 + k. g(x) = 8x^2 - 64x.

Answer: it would take 280 miles before Laura pays the same amount for both plans..
Step-by-step explanation:
Let x represent the number of miles that Laura drives using either the first plan or the second plan
Let y represent the total cost of x miles when using the first plan
Let y represent the total cost of x miles when using the second plan
The first plan has an initial fee of $55.98 and costs an additional $0.13 per mile driven. This means that the total cost of x miles would be
y = 0.13x + 55.98
The second plan has an initial fee of $69.98 and costs an additional $0.08 per mile driven.This means that the total cost of x miles would be
z = 0.08x + 69.98
To determine the number of miles that Laura would drive before the amount for both plans becomes the same, we would equate y to z. It becomes
0.13x + 55.98 = 0.08x + 69.98
0.13x - 0.08x = 69.98 - 55.98
0.05x = 14
x = 280
