Answer:
EF = 7 units
AD = 3 units
BC = 11 units
Step-by-step explanation:
Since it is an isosceles trapezoid and the midsegment is x, the sum of the bases divided by 1/2 is the value of the midsegment, x.
x = 1/2(x-4 + 2x-3)
x = 1/2x - 2 + x - 1 1/2
x = 1 1/2 x - 3.5
-1/2 x = -3.5
x = 7 units
EF = 7 units
AD = 7-4 = 3 units
BC = 2(7) - 3 = 11 units
Area=legnth times width
legnth=16 ft
width=3 ft
but wait, they want the area in squazre METERS
so convert feet to meters
1 foot=0.3048 meters
convert 16 feet and 3 feet to meters
16 feet=16 times 0.3048=4.8768
3 feet=3 times 0.3048=0.9144
so the area is now
legnth=4.8768 m
width=0.9144m
area=4.8768 m times 0.9144 m=4.45934592
round
4.0
answer is 4 square METERS
4 m^2
Answer:
The height of the ball is at it's maximum 1.5 units of time after launch.
Step-by-step explanation:
Suppose we have a quadratic function in the following format:

If t is negative, the maximu value of h(t) will happen at the point

In this question:

So

Then

The height of the ball is at it's maximum 1.5 units of time after launch.
I don't think you use a fraction. You multiply .6666 by 72 which equals 47.9952 or rounded 48. :)
