Answer:

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

Step-by-step explanation:

the equation of a circle with a center at (0, 8) and a radius of 9.

To frame the equation of the circle we use center radius form of equation

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

Where (h,k) is the center and 'r' is the radius

Given center is (0,8) and radius = 9

h = 0 , k= 8 and r= 9

Plug in all the values

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

(x-0)^2 + (y-8)^2= 9^2

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

Answer:

  1.1.1  sin(241°) = -√t

  1.1.2  cos(61°) = √(1 -t)

Step-by-step explanation:

<u>Given</u>:

 sin(61°) = √t

<u>Find</u>:

  1.1.1  sin(241°)

  1.1.2  cos(61°)

<u>Solution</u>:

1.1.1  sin(180° +x) = -sin(x)

  sin(241°) = -sin(61°) = -√t

__

1.1.2  cos(x) = √(1-sin²(x))

  cos(61°) = √(1 -(√t)²) = √(1 -t)

a group of 10 people ran an average of 2.7 miles in one week. if the first 4 people in the group averaged 3 miles, what did the
FromTheMoon [43]
In this question, 10 people average running distance is 2.7miles. Then the sum of their running distance would be: 10 people * 2.7 miles/people= 27 miles.

The group then divided into 2, 4 people with 3 miles average and 6 people with unknown average. Since the people are same like the 10 people group, their total running distance would be the same. The calculation would be:

total distance = group1 * average1 + group2 * average2
27 miles= 4 people * 3 miles/people + 6 people* average2
6 people * average2 = 27 miles -12 miles = 15 miles
average2= 15 miles/6people= 2.5 miles/people

Each face of a small cube has a surface area of 0.25 square meters. A larger cube has edges that are six times as long as the ed
Dennis_Churaev [7]

Answer:

D. 27 meters cubed

Step-by-step explanation:

The first step is to find the edge length of the small cube. The square root of 0.25 is 0.5, meaning that a larger cube with six times the edge length will have an edge of 0.5*6=3 meters. 3 meters cubed is 27 cubic meters, or option D. Hope this helps!

Answer:

7.

A.) -⅔

B.) 3/-2

Step-by-step explanation:

from 1 to -1 you have to go down 2

from 2 to -1 you have to go down 3

therefore your slope is -⅔

from 3 to 6 you go up by 3

from 1 to -1 you go down by 2

therefore your slope is 3/-2
