If sin θ = 1 over 4 and tan θ > 0, what is the value of cos θ?

1 answer:

6 0

If you were to calculate the EXACT number, the cosine of theta would be rad.15 over 4.
Sine is opposite over hypotenuse, so the opposite would be 1 and the hypotenuse would be 4. Using the Pythagorean Theorem, you will see that the last side to your triangle is the square root of 15 (AKA rad.15). Cosine is adjacent over hypotenuse, thus rad.15 over 4.

John is digging a hole for a swimming pool,the hole will be 28 feet long, 5 feet wide, 34 feet wide. How much cubic feet of dirt

ivann1987 [24]

Answer:

John need to remove 4760 cubic feet of dirt.

Step-by-step explanation:

Given:

John is digging a hole for a swimming pool,the hole will be 28 feet long, 5 feet wide, 34 feet wide.

Now, to find the cubic feet of dirt John need to remove.

Length = 28 feet.

Width = 5 feet.

Height = 34 feet.

As the swimming pool is in the shape of a rectangular prism.

So, we put formula of volume to get the cubic feet of dirt need to remove:

$Volume = length\times width\times height$

$Volume=28\times 5\times 34$

$Volume=4760\ cubic\ feet.$

Therefore, John need to remove 4760 cubic feet of dirt.

Answer:

Answer: 35/18

Step-by-step explanation:

$\frac{ \{ \frac{3}{4} - \frac{5}{2} \} }{ \{ \frac{3}{5} - \frac{3}{2} \}} = \frac{( - \frac{7}{4} )}{ (- \frac{9}{10} )} \\ \\ = \frac{7}{4} \div \frac{9}{10}$
