A= bh

A= .28*.34

.0952

If there are 9,500 of these, multiply that by .0952.

904.4= 9500*.0952 m^2

"C" 904.4 m^2 <em>is the correct answer.
</em>
I hope this helps!

Solve the following trigonometric question:<br> cos x=3 cos x-2

bija089 [108]

Answer:

x = 0°

Step-by-step explanation:

$\cos x = 3 \cos x - 2 \\ 2 = 3 \cos x - \cos x \\ 2 = 2\cos x \\ \cos x = \frac{2}{2} \\ \cos x =1 \\ \cos x =\cos 0 \degree \\ \huge \red{ \boxed{x = 0 \degree}} \\$

Use the image below to answer the following question. Find the value of sin x° and cos y°. What relationship do the ratios of si

aliya0001 [1]

Answer:

<u>Trigonometric ratios</u>

$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$

where:

$\theta$ is the angle
O is the side opposite the angle
A is the side adjacent the angle
H is the hypotenuse (the side opposite the right angle)

To find sin x and cos y, we must first find the length of the <u>hypotenuse</u> (PO) of the given right triangle.

To do this, use <u>Pythagoras' Theorem:</u>

$a^2+b^2=c^2 \quad \textsf{(where a and b are the legs, and c is the hypotenuse)}$

Given:

a = 6
b = 8
c = PO

$\implies 6^2+8^2=PO^2$

$\implies PO^2=100$

$\implies PO=\sqrt{100}$

$\implies PO=10$

Using the found value of the hypotenuse and the trig ratios quoted above:

$\implies \sf \sin(x)=\dfrac{6}{10}=\dfrac{3}{5}$

$\implies \sf \cos(y)=\dfrac{6}{10}=\dfrac{3}{5}$

Therefore, $\sf \sin(x)=\cos(y)$

An employees hourly raise went up from $10 per hour to $12 per hour. What is the rate of increase?

Anastaziya [24]

20% because:

rate of Increase = ( final - initial ) / initial * 100

rate of increase = ( 12 - 10 ) / 10 * 100

rate of Increase = 2 / 10 * 100

rate of Increase = 20
