Rafael must choose a number between 67 and 113 that is a multiple of, 2,4, and 5 . Write all the numbers that he could choose.

skelet666 [1.2K]

First, find out what the greatest common factor is between 2, 4, and 5.

This is 20. So any number divisible by 20 is also divisible by 2, 4, and 5. 

Now we find the list of numbers that are multiples of 20 between 67 and 113. 

The solutions are: 

80 and 100.

The ellipse with center C(2, -3), vertices V(-8,-3) and V2(12,-3), and foci F1(-4,-3) and F2(8,-3). 6.

Answer:

(x-2)²/100 + (y+3)²/64 = 1

Step-by-step explanation:

C (2,-3): h=2 k=-3

semimajor axis (CV): a=12-2=10

center-foci: c=8-2=6

semi minor axis: b² = a²-c²= 100 - 36 = 64

equation: (x-h)²/a² + (y-k)²/b² = 1

(x-2)²/100 + (y+3)²/64 = 1
