Answer:

The answer is 11/14 ft^2 or pi/4 ft^2

Step-by-step explanation:

The area of the sector bounded by that angle measure will be the area of the circle divided by 4

Area of the circle is;

pi * r^2

so the area here is;

22/7 * 1 * 1 = 22/7

divide this by 4

= 22/28 = 11/14 ft^2

Which ordered pair is the y intercept of y=2x^2+3x-3?

rosijanka [135]

Answer:

I think it's A - (0,-3)

Step-by-step explanation:

x,y

(0,-3)

y-intercept equation for this problem:

$y=2x^{2}+3x-3$

Break it down to smaller parts:

$2(0)^{2} +3(0) = 0$

$0 - 3 = -3$

Rewriting it in a neater way:

=> $y = 2(0)^{2} +3(0) -3\\y=-3$

Therefore, answer A / the first choice is correct

Answer:

5.8com shorter

Step-by-step explanation:

I used the pythagoremy theorem to find the missing side length.

$a^{2} +b^{2} = c^{2}\\5^{2} +3^{2} = c^{2}\\25+9= c^{2}\\34=c^{2} \\\sqrt{34} = {c}^{2}\\5.8cm$
