Answer:

$b = \sqrt{65}$

Step-by-step explanation:

${b}^{2} + {4}^{2} = {9}^{2} \\ {b}^{2} + 16 = 81 \\ {b}^{2} = 81 - 16 \\ {b}^{2} = 65 \\ b = \sqrt{65}$

I hope I helped you^_^

PLEASE HELP ! 15 POINTs!

Lapatulllka [165]

Answer:

Perimeter = 101.496 cm

Step-by-step explanation:

draw line from point C that is perpendicular to line AD. Call that point E.

tan 43° = 16.7/ED

0.9325 = 16.7/ED

ED = 17.909 cm

sin 43° = 16.7/CD

0.6820 = 16.7/CD

CD = 24.487 cm

Perimeter = AB + BC + CD + ED + AE

Perimeter = 16.7 + 21.2 + 24.487 + 17.909 + 21.2 = 101.496 cm

Which of the following equations is of an ellipse with x-intercepts at (1, 0) and (-1, 0), y-intercepts at (0, 3) and (0, -3), a

Diano4ka-milaya [45]

If you were to plot the x and y intercepts you would see that this will be a vertical ellipses, taller that it is wider. The formula for an ellipse is $\frac{ x^{2} }{b^2} + \frac{y^2}{a^2}=1$ . The "a" value is always the bigger value of the a and b. The bigger value, the a, will always go under the variable that is the major axis. The major axis for us is the y axis. a = 3, so 3 squared is 9. b = 1 and 1 squared is 1. So our equation will be $\frac{x^2}{1}+ \frac{y^2}{9}=1$ , choice a from above.
