Circumference = 3.14 * 2 * r  = 3.14 * 16  so r = 8

general equation is  (x - a)^2 + (y - b)^2 = r^2

So our Equation is   x^2 + (y + 2)^2 = 64  (answer)

A baker uses 1/2 cup of water for every 1/4 cup of sugar in a syrup recipe. If the baker follows the recipe proportions, which s
fredd [130]

The statements which are true are;

  • Choice B: The baker uses 1/2 cup of sugar for every cup of water because 1/2 ÷ 1/4 = 1/2.
  • Choice E: The baker uses 2 cups of water for every cup of sugar because 1/2 ÷ 1/4 = 2.

<h3>Ratios and Proportions</h3>

Since the baker uses 1/2 cup of water for every 1/4 cup of sugar.

Considering proportions; we have;

  • 1 cup of water for every 1/2 cup of sugar

Or

  • 2 cups of water for every cup of sugar;

This is because, 1/2 ÷ 1/4 = 2.

In ΔJKL, the measure of ∠L=90°, JL = 24, LK = 7, and KJ = 25. What is the value of the sine of ∠K to the nearest hundredth?
podryga [215]

<u>Given</u>:

Given that JKL is a right triangle.

The measure of ∠L is 90°

The length of JL = 24, LK = 7, and KJ = 25.

We need to determine the value of sine of ∠K.

<u>Value of sin ∠K:</u>

The value of sin ∠K can be determine using the trigonometric ratio.

Thus, we have;

sin \ \theta=\frac{opp}{hyp}

Substituting \theta=K, the side opposite to angle K is JL and the hypotenuse is JK

Thus, we have;

sin \ K=\frac{JL}{JK}

Substituting JL = 24 and JK = 25, we get;

sin \ K=\frac{24}{25}

Simplifying, we get;

sin \ K=0.96

     K=sin^{-1}(0.96)

     K=73.74^{\circ}

Thus, the measure of sine of ∠K is 73.74°
