Step-by-step explanation:
Area of a trapezoid =
height * ( sum of base lengths) / 2
So...let the height = h
One base = h + 3
And the other is h + 5
So...we have this
375 = h [ (h + 3 + h + 5 ] / 2 multiply both sides by 2
750 = h [ 2h + 8 ]
750 = 2h^2 + 8h rearrange as
2h^2 + 8h - 750 = 0
Using the quadratic formula....we get the answer ≈ 17.468 = 17.5 yards (rounded)
"b" is correct
For the quadratic equation
ax2+bx+c=0
the formula for the roots is
x=−b±√b2−4
ac2a(1)
Identify the values for
a,b,&cx2+4x+3=0
cmp
ax2+bx+c=0a=1b=4c=3(2)
Substitute these numbers into eh formula
x=−4±√42−(4×1×3)2×1(3)
Carefully proceed and do the calculations
x=−4±√16−122x=−4±√42x=−4±22
now calculate the two separate solutions
x1=−4+22=−22=−1x2=−4−22=−62=−3

Answer:
33.1698
Step-by-step explanation:
10
∫ 13y/ y^2-9y-22 .dy
-1
Let's break down the fraction first before we integrate
13y/ y^2-9y-22
= 13y/(y-11)(y+2)
=11/(y-11) + 2/(y+2)
Time to Integrate.
10
∫ 13y/ y^2-9y-22 .dy
-1
=∫ 11/(y-11) dy+ ∫ 2/(y+2) Dy
= 11In(y-11) + 2 In(y+2)
When y = 10
= 11In(10-11) + 2In(10+2)
= 11In1 + 2In12
= 4.9698
When y = -2
= 11In(y-11) + 2 In(y+2)
= 11In(-2-11) + 2In(-2+2)
= -28.2
4.9698+28.2= 33.1698
