2. Write the equation of the circle with a center at
(-2, -8) and a radius of v10.

A. (x + 2)^2 + (y + 8)^2 = 25
B. (x - 2)^2 + (y – 8)^2 = 10
C. (x + 2)^2 + (y + 8)^2 = 10
D. (x + 2)^2 + (y + 8)^2 = 100
E. (x - 2)^2 + (y - 3)^2 = 100

Answers

Answer 1

Answer:

C. [tex] (x +2) ^2 +(y+8)^2 =10 [/tex]

Step-by-step explanation:

Center of the circle (h, k) = (-2, - 8)

Radius [tex] r=\sqrt {10}[/tex]

Equation of circle in center radius form is given as:

[tex] (x - h) ^2 +(y-k) ^2 =r^2 [/tex]

Plugging the values of h, k and r in the above equation, we find:

[tex] [x - (- 2)] ^2 +[y-(-8) ]^2 =(\sqrt {10})^2 [/tex]

[tex] (x +2) ^2 +(y+8)^2 =10 [/tex]

Answer:

C. 5/3 (5 sqrt 3) (8.66...)

Explanation:

You would use the SohCahToa to find out side x.

First, label your sides (10 is hypotenuse, x is the opposite, and blank side is the adjacent).

Second, figure out which part you have to use (Sin, Cosine, or Tangent). A good way to tell is of you have the missing side on top of the fraction, makes things easier.

Third, once you figure that out then plug stuff in...

Sin(theta) = O/H
Sin(60) = X/10
10sin(60) = X
8.66... = X

Answer:

G

Step-by-step explanation:

In the equation, 8.5 will represent how much money Oscar earns per hour, and the x represents how many hours he works. The inequality sign shows that the sum of 8.5x and 100 has to be at least 397.50 (397.50 and up), so H and J are automatically wrong. If Oscar had given his brother 100 dollars, there would be a subtraction sign, but there is an addition sign instead, meaning he gained 100 dollars that did not come from his job. It would be the most logical to say that his brother had given it to him, so G is the correct answer.

Answers

Answer:

2.52

Step-by-step explanation:

5x + 15.5 = 28.1

subtract 15.5 from both sides

5x = 12.6

divide both sides by 5

x = 2.52

Answer:

x=2.52

Step-by-step explanation:

28.1 = 15.5 + 5x

(take 15.5 from both sides)

28.1-15.5=15.5-15.5+5x

12.6=5x

(Divide both sides by 5)

12.6/5=5x/5

In an arithmetic sequence, the first term, a_1,a
1 , is equal to 5,5, and the fifth term, a_{5},is equal to 41.41. Which number represents the common difference of the arithmetic sequence?

Answers

Answer:

  10

Step-by-step explanation:

The general term of an arithmetic sequence is given by ...

  an = a1 +d(n -1) . . . . where a1 is the first term and d is the common difference

__

This formula can be used to find the value of d. The first term is given as 1, and the 5th term (a5) is given as 41. The value of n for the 5th term is 5.

  an = a1 +d(n -1)

  41 = 1 +d(5 -1) . . . . . substitute known values

  40 = 4d . . . . . . . subtract 1, simplify

  10 = d . . . . . . divide by 4

The common difference of this sequence is 10.
