You practice your basketball shots every day. On Friday you made 20 shots. On Saturday you made 16 shots. What is the percent de
STatiana [176]
So,

All you have to do to find the percent decrease is to subtract your score on Saturday from your score on Friday and divide the result by your score on Friday.  If you let "f" represent your score on Friday and let "s" represent your score on Saturday, you can re-write this mathematically:

\frac{f - s}{f} = percent\ decrease

Substitute.
\frac{20 - 16}{20} = percent\ decrease
\frac{4}{20} \ or\  \frac{1}{5}\ or\ twenty\ percent = percent\ decrease

The percent decrease in shots you made was 20%.  That would be option C.

Find the value of x. A. 53–√ in B. 241−−√ in C. 55–√ in D. 9
castortr0y [4]

Answer:

<h2>x = 5√3 inches</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

{a}^{2}  =  {b}^{2}  +  {c}^{2}

where a is the hypotenuse

Substitute the values into the above formula

The hypotenuse is 10 inches

We have

{10}^{2}   =  {5}^{2}  +  {x}^{2}

{x}^{2}  =  {10}^{2}  -  {5}^{2}

{x}^{2}  = 100 - 25

{x}^{2}  = 75

We have the final answer as

<h3>x = 5√3 inches</h3>

Hope this helps you

Write the equation of the circle whose center is (-4,8) and has a diameter of 18
svetoff [14.1K]

Answer:

(x + 4)^2 + (y - 8)^2 = 81

or

(x + 4)^2 + (y - 8)^2 = 9^2 depending on how your teacher wants it written.

Step-by-step explanation:

The standard form for a circle is

(x + h)^2 + (y + k)^2 = r^2

r is the radius.

You are given the diameter

r = d/2

r = 18/2

r = 9

So you already have the right hand side of the equation

(x + h)^2 + (y + k)^2 = 9*2

(x + h)^2 + (y + k)^2 = 81

You basically have h and k as well. They come from the center point.

h = 4

k = - 8

So the equation of the circle (and the answer) is

(x + 4)^2 + (y - 8)^2 = 81

One question remains. Why do the x and y values change signs? If you know what the distance formula is, then what you are finding is the distance r of all points on the circle from the center of the circle.

It is the distance formula that is actually the formula for the circle.
