Vertices: (4,13) and (4,3)<br> Foci: (4,11)and (4,5)<br> Write a equation
just olya [345]

Answer:

(x-4)²/16 + (y-8)²/25 = 1

Step-by-step explanation:

center (h,k): ((4+4)/2 , (3+13)/2) = (4 , 8)

a = 13-8 = 5        c = 8-5 = 3

b = √5²-3² = 4

Equation: (x-h)²/b² + (y-k)²/a² = 1

(x-4)²/16 + (y-8)²/25 = 1

What is the decimal multiplier to decrease by 2.7%?
MatroZZZ [7]

Multiplying by 1 keeps it the same. A number greater than 1 would be an increase and a number below 1 would be a decrease.

The decrease is 2.7% which is written as 0.027 as a decimal.

Subtract that from 1:

1 - 0.027 = 0.973

The multiplier would be 0.973
