PLEASE HELP!! I NEED THIS TO PASS.

Tanzania [10]

Let's apply the Law of Cosines here. We want the measure of the angle opposite the side with length 16.

Call that angle C.

Then 16^2 = 36^2 + 28^2 - 2(36)(28)cos C.

Solving for C: cos C = 16^2 - 36^2 - 28^2
------------------------- = 0.904, and C = 0.44 rad
-2(28)(36) or C = 25.21 degrees

So each of the 2 equal angles shown has the measure 25.21 degrees.

Unfortunately, I don't know the direction we should go from this point on.

-Dominant- [34]

Given

Your family has a circular swimming pool.

The radius of the pool is 9 feet and and its depth is 4 feet.

Find out the volume of the pool.

To proof

As depth is given in the question that means the shape of the swimming pool

is cylinder.

Formula

$Volume\ of\ cylinder = \pi r^{2}h$

where r = radius

h = height

now

radius of the pool is 9 feet and and its depth is 4 feet.

put all the values in the above equation

we get

$= \pi\times 9^{2}\times 4$

use 3.14 to approximate pi

$= 3.14\times 9\times9\times4$

we get

= 1017.4 ( approx )feet²

Hence proved

Reduce this algebraic fraction 27c^4d^5/9c^7d^4 ...?

Naddika [18.5K]

The answer is $\frac{3d}{ c^{3}}$

The fraction is: $\frac{27 c^{4} d^{5}}{9 c^{7} d^{4} }$
Let's rewrite it: $\frac{27 c^{4} d^{5}}{9 c^{7} d^{4} }= \frac{27}{9}*\frac{c^{4}}{c^{7}}*\frac{d^{5}}{d^{4} }$

Now, let's use the rule $\frac{ x^{a} }{ x^{b}} = x^{a-b} = \frac{1}{ x^{b-a} }$ :
$\frac{27}{9}*\frac{c^{4}}{c^{7}}*\frac{d^{5}}{d^{4} }=3* \frac{1}{c^{7-4}} * d^{5-4} =3* \frac{1}{ c^{3} } *d^{1}= \frac{3d}{ c^{3} }$

The temperature was −10 °F and dropped by 16 °F. Which statement represents the resulting temperature in degrees Fahrenheit?

emmainna [20.7K]

Answer:

-26

Step-by-step explanation:

Dropping here means subtracting. That means that we calculate:

-10 - 16 = -26
