Answer:
Step-by-step explanation:
We want to write the quadratic equation whose roots are 2 and -2, and whose leading coefficient is 4.
Since 2 and -2 are roots, are factors of this quadratic function.
The factored form is given as:
Since the leading coefficient is 4, a=4
Therefore the equation becomes:
Recognize and expand using difference two squares.
The required equation is:
Answer:
Answer: (0.974, 1.056) liters
Step-by-step explanation:
Answer: m < 1
x² - 2x + m = 0 (*)
a = 1 b = -2 c = m
Δ = b² - 4ac = 4 - 4m
(*) has 2 district real solutions => Δ > 0
⇔ 4 - 4m > 0
⇔ 4m < 4
⇔ m < 1
Step-by-step explanation:
The area of the circle is 50.27 yards.
The volume of a cone is
V = (1/3) π r² h
where r = radius of the base
h = the height.
The volume of the frustum is
(1/3)π(7.5²)(11+8) - (1/3)π(3.5²)(8)
=(1/3)π(7.5²)(19) - (1/3)π(3.5²)(8)
The 3rd choice is the correct answer.
