Answer:
Unless I am an idiot here (think I am) it is AE s the length between A and E, so it is 8
Step-by-step explanation:
Every side of the square is 16.
A to E is half of a side of the square, not a full side.
So you divide 16 by 2, getting 8.

Which is the corresponding angle
Answer:
4 and 8Step-by-step explanation:
4 and 8 are corresponding angles as they form at parallel lines cut by a transversal.
4 and 3 are supplementary angles (they both add up to 180°).
4 and 1 are vertically opposite angles and are equal to each other.
From the above explanations, only 4 and 8 are corresponding angles.
I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!

WHICH STAMENT IS TRUE ABOUT THE GRAPH SHOWN
What is the domain and range of the inverse of: f (x)= (x + 2)² - 1
Answer:
The inverse of this function is a parabola that has been rotated 90 degrees clockwise, with it's vertex at point 1, 0.
So it's domain is x ≥ 1
And it's range is y ≥ -2
Step-by-step explanation:
Given:
f(x) = (x + 2)² - 1
First we find the inverse:
x = (f(x) + 2)² - 1
x - 1 = (f(x) + 2)²
√(x - 1) = f(x) + 2
f(x) = -2 ± √(x - 1)

Answer:
m=-2 b=0
Step-by-step explanation:
first, in order to understand anything, you gotta know what y=mx+b means :)
first, m is just there so you can substitute it for a number. x represents the slope, and b represents the y-intercept, which you also substitute for a number.
so in y= -2x, there's no y intercept, because there is no number that represents the y intercept.
so if we use y=mx+b, we can just substitute the numbers.
which would be, y= -2.

(20x^2 – 3x – 9)/(4x – 3)
Answer:
5x+3
Step-by-step explanation:
Rewrite the expression to 20x^2-3x-9/4x-3
Factor 20x^2+12x-15x-9/4x-3
Factor 4x*5x+3-3(5x+3)/4x-3
Factor (5x+3)*(4x-3)/4x-3
Solution then becomes 5x+3 as stated above

Hey please help, I'm pretty sure it's C, but I'm not sure if it's a also
Answer:
It is only C
Step-by-step explanation:
The only answer for this is C
The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".
What is Arc length?The arc length is defined as the interspace between the two points along a section of a curve.
Here, we know that,
angle = arc length / radius ............(i)
If arc length / radius = 1 ............(ii)
then from eq. (i) and (ii), we get
angle = 1
θ = 1
Thus, The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".

PLEASE HELP ME WITH THIS GUYS!!
Answer:
C
Step-by-step explanation:
So they bought 2 sneakers. A pair of sneakers cost $6.49. Multiply that by 2, and you get $12.98.
Then they bought a pair of flip flops. So one pair is $0.99. Add that to the $12.98 you got and now you have $13.97.
They also got a pair of flats. One pair is $7.19, so add that to your $13.97 and you now have $21.16.
They also have to pay $1.75 tax, meaning you add that to the $21.16 you have which makes $22.91 total.
But they said how much change they would get from $30 so we're not done yet. So subtract $22.91 from $30 and your answer will be $7.09 which is C.

Step-by-step explanation:
Calculate the perimeter of the shape to the nearest whole number
Answer:
Option B
Step-by-step explanation:
Perimeter of the given figure = Sum of measures of all sides
= AB + BC + CA
Since, AB = BC = 9 cm (Radii)
CA = Length of arc CA which is the quarter of the circumference of a circle with radius 9 cm
CA = [tex]\frac{1}{4}(\text{Circumference of the circle})[/tex]
= [tex]\frac{1}{4}(2\pi r)[/tex]
= [tex]\frac{1}{2}(\pi )(9)[/tex]
= 14.14 cm
Now perimeter of the shape = 9 + 9 + 14.14
= 32.14 cm
≈ 32 cm
Therefore, Option B will be the correct option.
