Answer:

  2

Step-by-step explanation:

The distance between foci is the root of the difference of the squares of the axes lengths:

  d = √(10² -8²) = √36 = 6

Then the radius of the circle is half the difference between this and the length of the major axis:

  r = (10 -6)/2 = 4/2

  r = 2

What is the slope intercept form of the points -3,-10 and 5,14
Ksenya-84 [330]

Answer:

y = 3x - 1

The slope intercept is -1.

To find the slope, do the formula (y sub2 minus y sub1)/(x sub2 minus x sub1) then reduce.

(14 - (-10))(5 - (-3)) = 24/8

24/8 = 3

Given the point (18, -10), apply the rule and tell the image after the translation as an ordered pair with no spaces.
Phantasy [73]

Answer:

The answer is (7,-19)

Step-by-step explanation:

Remember, 18 is x, and -10 is y. The rule says to subtract 11 from 18, which would be 7. For y, you add -9 to -10, which would be -19.

Therefore, your answer should be (7,-19)

Hope this helps!

Cassie has a small cube shaped box. Its volume is 64 cubic cm. What is the area of one face of tje box.
Andrews [41]

Answer:  One face is 16 square centimeters.

Step-by-step explanation: To find the area of a face, you need to know the length of the side. All the sides of the cube are the same, so take the cube root of 64.

\sqrt[3]{64}=4 cm is the length of the side

The area of one face is the side length squared 4² = 16

4cm × 4cm = 16 square centimeters.
