Answer:

4/5

Step-by-step explanation:

Sin = Opposite / Hypotenuse

Note that hypotenuse = longest side

We want to find sinФ

The opposite side length of angle "Ф" has a length of 8 and the longest side or hypotenuse has a length of 10

So sinФ would equal 8/10 which can be simplified to 4/5

Emily wants to know the volume of a beach ball. She deduces that the beach ball has diameter of 12 inches, and then uses the fol

Over [174]

Answer:

D. She used the beach's ball's diameter when she should have used the radius

Step-by-step explanation:

To find the volume of the beach ball, using the volume of a sphere is the right formula to use, which is ⁴/3πr³.

The formula she used is correct.

Since the diameter of the ball is assumed to be 12 inches, what is needed to find the volume is the radius.

Radius (r) = ½(diameter) = ½(12) = 6 in.

This is where Emily made a mistake.

She used the diameter of the beach ball instead of its radius (r) which is needed in the equation.

She should have gotten,

V = ⁴/3(3.14)(6)² = 904.32 cubic inches

Please help, will give brainliest to first

Lelechka [254]

Answer:

AN = 16 units

Step-by-step explanation:

So we can use the fact that $\frac{AN}{FN} =\frac{OR}{FR}$

Since this is an isosceles triangle, segments FO and FR are both equal to 7

Manipulating the equation above to solve for AN we have $AN = \frac{(FN)(OR)}{FR}$

Substituting in the known values we have $AN=\frac{(10)(11.2)}{7} =16$

Find the product. (x-3)^2

r-ruslan [8.4K]

Greetings and Happy Holidays!

Find the Product:
$(x-3)^2$

Expand:
$=(x-3)(x-3)$

Use FOIL or other techniques to solve binomial multiplication:
$=x(x-3)-3(x-3)$

$=x^2-3x-3(x-3)$

$=x^2-3x-3x+9$

Combine like terms:
$=x^2-6x+9$

The Answer Is:
$\boxed{=x^2-6x+9}$

I hope this helped!
