Answer:

∠B ≈ 56.25°

Step-by-step explanation:

Since the triangle is right use the cosine ratio to solve for B

cosB = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{5}{9}$ , thus

B = $cos^{-1}$ ( $\frac{5}{9}$ ) ≈ 56.25°

Answer:

∠B = 56.25

Step-by-step explanation:

We would use cosine function here.

cos Θ = $\frac{adjacent}{hypotenuse}$

cos Θ = $\frac{5}{9}$

cos⁻¹ ( $\frac{5}{9}$ ) = 56.25

Question 15 of 25

Slav-nsk [51]

Answer:

Step-by-step explanation:

Polynomials are factored after they are set equal to 0. This i because the factors of the polynomial are also known as the x-intercepts, and x-intercepts exist where y = 0. Therefore, if the factors of the polynomial are

(x + 8)(x + 4) = 0, then by the Zero Product Property,

x + 8 = 0 so x = -8 or

x + 4 = 0 so x = -4. Choice A.

Which expression is equivalent to x6 - 16x^2?

Mrac [35]

Answer:

$x^2(x - 2)(x + 2)(x^2 + 4)$

Step-by-step explanation:

$x^6-16x^2$

$x^2\left(x^4-16\right)$

$x^2\left(x^2+4\right)\left(x+2\right)\left(x-2\right)$

Which of the following expressions does not equal: the sixth root of 81x^4y^8

DerKrebs [107]

$\sqrt[6]{81x^4y^8}=\left[3^4x^4(y^2)^4\right]^\frac{1}{6}=\left[\left(3xy^2\right)^4\right]^\frac{1}{6}\\\\=\left(3xy^2\right)^{4\cdot\frac{1}{6}}=\left(3xy^2\right)^\frac{2}{3}\to A\\\\=\left(3xy^2\right)^\frac{2}{3}=\sqrt[3]{\left(3xy^2\right)^2}=\sqrt[3]{9x^2y^4}\to D\\\\=\left(3xy^2\right)^\frac{2}{3}=\left(3x\right)^\frac{2}{3}y^{2\cdot\frac{2}{3}}=\left(3x\right)^\frac{2}{3}y^\frac{4}{3}\to B\\\\\\Answer:C$
