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
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]

Find cot theta if 180° < theta < 270° and cos theta = - sqrt 3/2
Answer:
cot theta = -√3
Step-by-step explanation:
we are given that cos theta = - √3/2 within the range 180° < theta < 270° and
since cos theta = adj/hyp
adj = - √3
hyp = 2
Get the opposite using the pythagoras theorem
hyp^2 = opp^2 + adj^2
2² = opp² + (-√3)²
4 = opp² + 3
opp² = 4-3
opp² = 1
opp = 1
tan theta = opp/adj
tan theta = - 1/√3
Recall that cot theta = 1/tan theta
cot theta = 1/(-1/√3)
cot theta = -√3

Answer:
C) 1.25
Step-by-step explanation:
The hypotenuse is the sloping side.
The base is the bottom side.
The triangles are similar, so you can use the sides of either triangle. Let's use the side lengths of the smaller triangle.
Length of hypotenuse: 5
Length of base: 4
Ratio of hypotenuse to base: 5/4
To find a decimal value, divide 5 by 4. Use a calculator or long division.
5/4 = 1.25
Answer: C) 1.25

The graph x² + ( y²/49 )>1 is correct. The correct option is A.
What is inequality?Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
The given inequality is x² + ( y²/49 )>1;. The graph is plotted on the x-y plane. The curves of the graph cut the y-axis at positive 7 and negative 7 and cut the x-axis at positive 1 and negative 1.

Write the number as a percent.
3/20
Answer:
15%
Step-by-step explanation:
not that hard just make it a decimal then at the point go back twice and there its 15%
Answer:
15%
Step-by-step explanation:
Since 100 isn't the denominator we need to make it a denominator.
3/20 x 1/5 = 3/100 we need to do the same to the denominator because whatever we do to the denominator has to do with the numerator 3 x 5 = 15,
15/100 means 15%!

The Wiggins Family ate dinner at a restaurant. The total cost of the meal was $85.60. The family left a 15% tip for the waiter. How much money was the total bill? (Make sure you type your answer using $ and the decimal)
Fast please
Answer:
$98.44
Step-by-step explanation:
You already know how much the actual dinner was so all you have to do is figure out how much 15% of the $85.60 is which is $12.84 meaning that they left a tip of $12.84 for the waiter. Then you would just add the cost of the dinner with the tip to get the total amount they spent. $85.60 + $12.84 = $98.44. So the total amount the Wiggins spent is $98.44
