Answer:
4
Step-by-step explanation:
8000 because 3 is less than 5 so you stay the same (which is 8)
You need to find where the discriminant is less than zero
Remember the discriminant is b^2 - 4ac
a = m
b = -5
c = -2
Set up the inequality like this
(-5)^2 - 4m(-2) < 0
25 + 8m < 0
8m < -25
m < -25/8 < -3.125
So any number less than -3.125 will make this graph have no x-intercepts (or real roots)
Answer:
The height of the trapezoid is 4ft
Step-by-step explanation:
First of all, to solve this problem we need to use the area formula of a trapezoid:
A = area = 20ft²
b1 = base 1
b2 = b2
h = height
b1 + b2 = 10ft
A = ½ (b1+b2) * h
we replace with the known values
20ft² = ½ (10ft) * h
20ft² = 5ft * h
20ft² / 5ft = h
4ft = h
The height of the trapezoid is 4ft
