Write an equation of the circle with center (-7, 4) and radius 8.

Mathematics
1 answer:
Stels [109]3 years ago
7 0

answer

(x+7)^2 + (y-4)^2 = 64

set up equation

the equation of a circle is (x - h)^2 + (y - k)^2 = r^2

where h is the center x coordinate and k is the center y coordinate

values

from the point (-7,4) we know that h = -7 and k = 4

since the radius is 8, r^2 = 8^2 = 64

plug in values

now that we have all the values, we plug them into (x - h)^2 + (y - k)^2 = r^2

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

(x - (-7))^2 + (y-4)^2 = 64

(x+7)^2 + (y-4)^2 = 64

Is the following conditional true? If p<2, then p≤2.
Romashka-Z-Leto [24]
If this is the only information you are given then no. This is because the < sign means that p is less than 2. The second sign cannot be true if the first one is because the second sign says that p is less than or equal to 2.

After 5 throws in a game of darts, Brent's mean score was 32. Calculate his total score.
ehidna [41]

1.To know this answer, we need to know some vocabulary that's used in t. Most people don't know how to solve questions if they have hard Vocabulary and what the question is Asking

Mean=The average of all his throws

It's asking us to calculate his total score  

2. Find Clues to help you solve word problems

Finding clues in Word Problems is a very important part a lot of people skip but this helps you solve the question easier

5 throws and Mean Score is 32 are the clues

3. Guess and check

The method to this thingy is called guess and check. There is another method which is slightly harder and i just don't want to do it.

Let's just say his scores were... 5, 6, 4, 5,10Add them up and you get 30Then 30/5

Let's try bigger numbers

20+25+20+20

If you like this method, you may try it another method is called work Backwards

5x32=160

Then divide 160 by 5 to double check and you get 32!!

========================================

Therefore, the answer s 160 as his total score

hope this gives you a clue to what we are doing and when you have a question like this, I really hope you understand the concept

Hope this helped (:

What is the slope of a line that is perpendicular to the line 2y – 3x = 8?
GarryVolchara [31]

Answer:

= \frac{3}{2}

Step-by-step explanation:

y = mx + c

Here,

<h2>m => slope</h2><h3>c => intercept</h3>

In this equation ,

2y - 3x = 8

to find the value of m or the value of slope we have to solve for y

<em>Let's</em><em> </em><em>solve</em><em>,</em>

<em>2y - 3x = 8 \\ 2y = 8 + 3x \\  \frac{2y}{2}  =  \frac{8 + 3x}{2}  \\ y = 4 +  \frac{3x}{2}  \\  y =  \frac{3x}{2}  + 4</em>

<em>So</em><em>,</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>slope</em><em> </em><em>is</em><em>,</em>

<em>= \frac{3}{2}</em>
