Answer:

Angle A = 97.5º

Step-by-step explanation:

Supplmentary means 2 angles that equal 180º. So we already have 1 angle, so now all we have to do is subtract 82.5 from 180.

180 - 82.5 = 97.5

Rewrite the equation by completing the square.<br>x^2-2x+1=0​
kaheart [24]

Answer:

(x - 1)² = 0

Step-by-step explanation:

Given

x² - 2x + 1 = 0 ( subtract 1 from both sides )

x² - 2x = - 1

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = - 1 + 1

(x - 1)² = 0

What is the greatest common factor of 20x6y+40x4y2−10x5y5 ?
mestny [16]
The greatest common factor: 20x^6y 40x^4y^2 10x^5y^5 is 10x^4y.
20x^6y = 10x^4y*2x^2
40x^4y^2 = 10x^4y*4y
10x^5y^5 = 10x^4y*y^4

Help anyone pleaseeee
AlexFokin [52]

Answer:

36 <127

(36,127°)

36 [ cos (127) + i sin (127)]

Step-by-step explanation:

w1 = 2 < 95

w2 = 18 < 32


w1 * w2

We multiply the magnitude and add the angles

w1 * w2 = 2*18 < (95+32)

            =36 < 127

             36 [ cos (127) + i sin (127)]

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

- have a great day, be safe & healthy -
