That guy was wrong, you don't deserve the 5 stars I was too early, it was 54.1; just took the test.

<span>ΔPQR is a right triangle
∡Q is a right angle.             ⇒⇒⇒ ∡Q = 90°
QR measures 33 point 8   ⇒⇒⇒ QR = 33.8 ⇒ leg of the triangle
PR measures 57 point 6   ⇒⇒⇒ PR = 57.6  ⇒ hypotenuse of the triangle

we can find ∡P using sin function
sin P = QR/PR = 33.8/57.6 = 0.5868
∴ ∡P = sin^{-1} 0.5868 ≈ 35.93°</span>

Y varies inversely as the fourth power of x and when x=3, y=1.
masya89 [10]

The constant of proportionality if y varies inversely as the fourth power of x and when x=3, y=1 is k = 3^¼

<h3>Inverse variation</h3>

y = k ÷ x^¼

where,

  • Constant of proportionality = k

When x = 3, y = 1

y = k ÷ x^¼

1 = k ÷ 3^¼

1 = k / 3^¼

  • cross product

1 × 3^¼ = k

k = 3^¼

Therefore, the constant of proportionality if y varies inversely as the fourth power of x and when x=3, y=1 is k = 3¼

BaLLatris [955]

Answer:

81°

Step-by-step explanation:

By the outside angle theroem, we know that 2 * angle APC is differece of arcs DC and AB.

Angle APC = 27° so the difference is 54°

Arc DC = 27°, so Arc AB =  27° + 54° or 81°.

How the equation y=7.5x + 50 shows the slope and the y-intercept
iris [78.8K]

Answer:

slope:7.5, y-intercept:50

Step-by-step explanation:

The basic equation for slope is y=kx+b

In this equation, k stands for slope and b stands for y-intercept.

So in y=7.5x+50, k is 7.5 and b is 50 which equal to slope is 7.5 and y-intercept is 50
