Answer:

sinθ = 12/15 -> 4/5

cosθ = 9/15 -> 3/5

tanθ = 12/9 -> 4/3

cscθ = 15/12 -> 5/4

secθ = 15/9 -> 5/3

cotθ = 9/12 -> 3/4

Step-by-step explanation:

The theta is where you would use to identify the numbers for the trig functions. The adjacent side is the one closest to the theta (but not the diagonal line, that is the hypotenuse), and the opposite line is the line next to the adjacent line.

For the first three trig functions, would use the method Soh Cah Toa.

Sin = opp/hypotenus, Cosine = adjacent/hypotenuse, and Tangent = opposite/adjacent. Then, there is cosecant(csc) = hyp/opp, secant = hyp/adj, and cotangent = adj/opp.

5. Solve for each inverse. a. If y = 4x - 10, solve for x.

GREYUIT [131]

Answer:

x = $\frac{y+10}{4}$

Step-by-step explanation:

Given

y = 4x - 10 ( add 10 to both sides )

y + 10 = 4x ( divide both sides by 4 )

$\frac{y+10}{4}$ = x

Find the volume of the compound shape.

jeyben [28]

<h3>Given:</h3>

Hemisphere ×2 or sphere
Cylinder

<h3>Solution:</h3><h3>Volume of the sphere:</h3>

$v = \frac{4}{3} \pi {r}^{3}$

$v = \frac{4}{3} \times \pi \times {2}^{3}$

$v = 33.51 \: {m}^{3}$

<h3>Volume of the cylinder:</h3>

$v = \pi {r}^{2} h$

$v = \pi \times {2}^{2} \times 6$

$v = 75.40 \: {m}^{3}$

<h3>Total volume:</h3>

$v = 75.40 + 33.51$

$v = 108.91 \: {m}^{3}$

Hence, the volume of the given compound shape is 108.91 cubic meters.

A line passes through the point (4,1) and has a slope of 5/4

LenKa [72]

Y=5/4x-4
5/4 is the slope but to pass through the point it needs to cross the y axis at -4

A water bottle holds 3 1/3 c of water. A bowl holds 2 1/4 times the amount in the water bottle. How much water does the bowl hol

kodGreya [7K]

First you would put both numbers into improper fractions.

3 1/3 = 10/3 and 2 1/4 = 9/4

Multiply 10/3 * 9/4

10*9 = 90 and 3 * 4 =12

So 90/12 is your fraction. Reduce it, 7 6/12

7 6/12 = 7 1/2

So your answer is 7 1/2

Hope I helped :)
