What expression is equal to COS B????

Mathematics
1 answer:
Murrr4er [49]3 years ago
3 0

Answer:

A/C

Step-by-step explanation:

Since the sum of the angles in a triangle equals 180°, and angle C is 90°.

That means angles A and B add up to 90°, that is, they are complementary angles. Therefore the cosine of B equals the sine of A.

We saw on the last page that sin A was the opposite side over the hypotenuse, that is, a/c. Hence, cos B equals a/c.

Your welcome! :)

100-3y+4y-3y2 simplified btw I don't have a lot of points
erastova [34]

Answer:

-3y^2 + y + 100

Step-by-step explanation:

Combine like terms.

-3y+4y = 1y or "y"

Add "y" back into the equation.

-3y^2 + y + 100

The equation cannot be simplified any further.

I hope this helped!

If y varies inversely with the square of r, what is the constant of proportionality when y - 10 and 1 = 5?
Anvisha [2.4K]

<em><u>Question:</u></em>

If y varies inversely with the square of r, what is the constant of proportionality when y =10 and r = 5?

<em><u>Answer:</u></em>

The constant of proportionality is 250

<em><u>Solution:</u></em>

Given that,

y varies inversely with the square of r

Which means,

y \propto \frac{1}{r^2}\\\\y = k \times \frac{1}{r^2}

Where, "k" is constant of proportionality

Subtitute y = 10 and r = 5

10 = k \times \frac{1}{5^2}\\\\10 = k \times \frac{1}{25}\\\\k = 10 \times 25\\\\k = 250

Thus the constant of proportionality is 250
