Answer:
-93
Step-by-step explanation:
Step one:
given the expressions
we want (fog)(-3).
but (fog) is
Step two:
fog(-3)= put x= -3 in (fog)(-3)=-8x^2-20x+32+7
Step-by-step explanation:
The approximate stopping distance d(in feet) is given by the formula :
...(1)
Where
v is the speed of the car in mph
We need to find the speed of the car when the distance is 200 feet
Put d = 200 in equation (1)
It is a quadratic equation. Divide the above equation by 0.05.
The solution of the above equation is given by :
Since, 1 mph = 5280 ft/hour
44.96 ft/h = 0.00851 mph
-88.96 = -0.0168 mph
Hence, this is the required siolution.
Answer:
y=-2x+3
Step-by-step explanation:
slope-intercept form is in y=mx+b
Transforming the equation: 4y=12-8x
4y=-8x+12
Therefore, y=-2x+3
Answer:
0
Step-by-step explanation:
because when you square a number, you multiply it by itself. So, you would do 0 x 0 = 0
Hope this helps!
