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:
B. 50.24
Step-by-step explanation:
to find the area of a circle you need to use the formula
a=r²π
since the radius is 4 we put that into the equation, lets use 3.14 for pi
a=(4)²×3.14
always do exponents first
a=16×3.14
a=50.24
12a+24 = 90 because all angles in a rectangle equal 90 degrees.
Subtract 24 from both sides.
12a=66
Divide both sides by 12
a=5.5
Answer: 25/6
Step-by-step explanation:
Answer: 6 hours
This one seems pretty obvious. It's a ratio
2 : 1/3 = x : 1
with the solution x=6.
