Explain WHY a rotation of 180° is the same as doing<br> reflection over the x-axis AND the y-axis?
Effectus [21]
The 180 degree acts like both a horizontal (y axis) and vertical (x axis) reflection in one action.Precisely. Although they appear similar at first,rotating a figure 180 degrees swaps the image left-to-right and top-to-bottom at once.

What’s the answer thank you for your help
frez [133]
The formula for finding the sum of a finite geometric series is
S_n = a_1( \frac{1-r^n}{1-r} )

n = 17, a_1 = 3, r = 2

Substitute into the formula and you get 393213

If sin θ=.55 what is the value of cos θ and explain why
MatroZZZ [7]

Answer:

cos(\theta)=(+/-)0.84

Step-by-step explanation:

we know that

sin^2(\theta)+cos^2(\theta)=1 ----> by trigonometric identity

we have

sin(\theta)=0.55

substitute

(0.55)^2+cos^2(\theta)=1

cos^2(\theta)=1-(0.55)^2

cos^2(\theta)=0.6975

cos(\theta)=(+/-)\sqrt{0.6975}

cos(\theta)=(+/-)0.84

Remember that

If the sine of angle theta is positive, then the angle theta lie on the I Quadrant or II Quadrant

therefore

If the angle theta is on the I Quadrant the cosine  will be positive

If the angle theta is on the II Quadrant the cosine  will be negative
