aksik [14]

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:

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

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

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

Given f(x)=2x+3 find x=9 show your work

Allushta [10]

Answer:

f(9) =21

Step-by-step explanation:

I will assume you want to find f(9) when x=9

Let x=9

f(9) = 2(9) +3

= 18+3

=21

f(9) =21

There is a bag filled with 4 blue and 5 red marbles.

kkurt [141]

Answer:

5/9

Step-by-step explanation:

There are 4 blue, 5 red and total of 9 marbles.

<u>If two marbles are taken and we are looking for exactly one red, then it is:</u>

red, then blue or blue, then red

<u>Find the probability of each case:</u>

P(r, b) = 5/9*4/8 = 5/18
P(b, r) = 4/9*5/8 = 5/18

<u>Probability of exactly one red:</u>

P = 5/18*2 = 5/9
