Find the center, vertices, and foci for the ellipse 25x^2 + 64y^2 = 1600
Alisiya [41]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

Equation               25x² + 64y² = 1600

Process

1.- Divide all the equation by 1600

                             25x²/1600 + 64y²/ 1600 = 1600/1600

-Simplify

                              x²/64 + y²/ 25 = 1

2.- Equation of a horizontal ellipse

                             \frac{x^{2} }{a^{2}} + \frac{y^{2}}{b^{2}} = 1

3.- Find a, b and c

    a² = 64             a = 8

    b² = 25             b = 5

-Calculate c with the Pythagorean theorem

                   a² = b² + c²

-Solve for c

                   c² = a² - b²

-Substitution

                   c² = 8² - 5²

-Simplification

                  c² = 64 - 25

                  c² = 39

-Result

                  c = √13

4.- Find the center

          C = (0, 0)

5.- Find the vertices

          V1 = (-8, 0)     V2 = (8, 0)

6.- Find the foci

          F1 = (-√13, 0)   F2 = (√13, 0)

Given an exponential function for compounding interest, A(x) = P(.95)x, what is the rate of change?
statuscvo [17]

Answer:

Option 3

The rate of change is -5%                

Step-by-step explanation:

Given : An exponential function for compounding interest, A(x) = P(.95)^x

To find : What is the rate of change?

Solution :

The general form of an exponential function is:

f(x) = a(1+r)^x

Where, a is the initial amount,

(1+r) is the rate of change,

r is the growth or decay factor

We have given, A(x) = P(.95)^x

Rate of change is

1+r=0.95

r=0.95-1

r=-0.05

Convert to percent,

r=-0.05\times 100=-5\%

Therefore, Option 3 is correct.
