Answer:

∠ A ≈ 59.5°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinA = $\frac{opposite}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{56}{65}$ , then

A = $sin^{-1}$ ( $\frac{56}{65}$ ) ≈ 59.5° ( to 1 dec. place )

Circle A has radius 4 feet. Circle B has radius 9 feet. What is the ratio of the area of circle A to the area of circle B?

yaroslaw [1]

Answer:

$\large\boxed{\dfrac{16}{81}}$

Step-by-step explanation:

The formula of an area of a circle:

$A=\pi r^2$

r - radius

Circle A:

radius = 4 ft. Substitute:

$A_A=\pi(4^2)=16\pi\ ft^2$

Circle B:

radius = 9 ft. Substitute:

$A_B=\pi(9^2)=81\pi\ ft^2$

The ratio:

$\dfrac{A_A}{A_B}=\dfrac{16}{81}$

If rhe discriminant of a quadratic equation is equal to -8 which statement describes the roots

Nastasia [14]

Answer:

Step-by-step explanation:

Given

$Discriminant = -8$

Required

Determine the type of roots

Represent Discriminant with D; such that

$D = -8$

D is calculated as thus

$D = b^2 - 4ac$

And it has the following sequence of results

When $D > 0;$ then the roots of the quadratic equation are real but not equal

When $D = 0;$ then the roots of the quadratic equation are real and equal

When $D < 0;$ then the roots of the quadratic equation are complex or imaginary

Given that $D = -8$ ; This means that $D < 0;$ and base on the above analysis, we can conclude that the roots of the quadratic equation are complex or imaginary
