Since 1 hour = 60 minutes,
Hence, 120 miles/hour = 120 miles / 60 minutes = 2 miles/minute
Answer:
Option A: 12
Step-by-step explanation:
From the image of the triangle given, we can see that:
XM = ZM
We are given that:
XM = 2x + 2 and ZM = 4x - 8
Thus;
2x + 2 = 4x - 8
Rearrange to get;
4x - 2x = 8 + 2
2x = 10
x = 10/2
x = 5
Thus, XM = 2(5) + 2
XM = 12
I think the correct answer is 4.2
Answer:
or 
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to

where
a is a coefficient
x_1 and x_2 are the roots or x-intercepts of the quadratic equation
In this problem we have

substitute

<em>Find the value of a</em>
we have the y-intercept (0,37.8)
substitute the value of x and the value of y of the y-intercept in the equation and solve for a


so

Convert to expanded form
