Answer:

$\frac{x^2}{36} + \frac{y^2}{100} = 1$

Step-by-step explanation:

Required

The equation of the ellipse

This is calculated as:

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

Where:

$b =6$ ---- height

$a = 0.5 * 20 =10$ --- width

So:

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

$\frac{x^2}{6^2} + \frac{y^2}{10^2} = 1$

$\frac{x^2}{36} + \frac{y^2}{100} = 1$

Answer:

y = 50·3^x
(2, 450), (3, 1350), (4, 4050), (5, 12150)

Step-by-step explanation:

The problem statement tells you each observed count is 3 times the last one.

Expressed as an exponential function with an initial value of 50 and a growth factor of 3, the formula is ...

y = (initial value)×(growth factor)^x

y = 50·3^x
