Answer: a = 4
Step-by-step explanation: Area of a triangle is calculated as:
.
The triangle formed by the parabola has base (b) equal to the distance between the points where the graph touches x-axis and height (h) is the point where graph touches the y-axis.
The points on the x-axis are the roots of the quadratic equation:
a(x-3)(x+2)=0
(x-3)(x+2)=0
x - 3 = 0
x = 3
or
x + 2 = 0
x = -2
So, base is the distance between (-2,0) and (3,0).
Since they are in the same coordinate, distance will be:
b = 3 - (-2)
b = 5
Area of the triangle is 10. So constant a is

5a = 10.2
a = 4
The constant a of the function y = a(x-3)(x+2) is 4.
A graph shows the appropriate choice to be
A. 277.8 °F
_____
Of course, you get the same result by evaluating
76 + 301*e^(-0.40)
U= 9.4m/s
v= -7.4m/s (Negative sign because it is in the opposite direction as he is rolling back)
t= ?
s= ?
a= ?
Now, a= v-u/t
= -7.4-9.4÷3
=-5.6
By the second equation of motion.
s= ut+1÷2at*2 ( *2 is the power)
s= 9.4×3+1÷2×-5.6×3*2
= 28.2 +(-25.2)
=3
Therefore s or the distance travelled is 3m.
Answer:
i got 96
Step-by-step explanation:
you have to find the unit rate for 1 driveway and times that by 12
32 divided by 4 is 8
8 x 12 is 96
hope this helps :)
