I'm not 100% sure about this because this unit confused me but...
if you put it in your graphing calculator or in desmos, you can see that the first positive x -intercept (which is a point that is on the x-axis) is somewhere around one but it's not 1.571!! (other person is wrong!)
that point is (0.571, 0) so it's the first option

Find the area of quarter circle with the radius of 10
Answers
Answer: 78.5
Step-by-step explanation:
Formula: A=pi*r^2 or Area = 3.14*radius squared (by two)
A = 3.14*10^2
A = 3.14*100
A = 314
Divide it by 4, because it's a quarter of the circle: A = 314/4
A = 78.5

A circular flower bed is 23 m in diameter and has a circular sidewalk around it that is 4 m wide. Find the area of the sidewalk in square meters. Use 3.14 for π.
Answers
Answer: 244.92 m
Step-by-step explanation:
The area of a circle is pir^2. First you will need to find the area of the concrete and subtract the area of the flower bed from that amount. The concrete is 3 feet wide so you will add that to 11.5 (half of the flower bed diameter) to find the radius. 14.5^2 pi is the entirety of the area. Then subtract 11.5^2 pi for the area of the concrete.

verify the following
i.[ -3/4]3 = -27/64
ii. [-2/3]6 = 64/ 729
Answers
Answer:
The relationships are correct and valid
Step-by-step explanation:
The correct question is as follows;
Verify the following
i.[ -3/4]^3 = -27/64
ii. [-2/3]^6 = 64/ 729
We have the solution as follows;
i) we have;
(-3/4)^3
That means ;
-3^3 = -3^3 = -27
4^3 = 64
so;
(-3/4)^3 = -27/64
ii) (-2/3)^6
(-2)^6 = 64
3^6 = 729
Thus;
(-2/3)^6 = 64/729

Please help! 30 points and crown! A diagonal of a cube measures StartRoot 750 EndRoot cm. The diagonal of a face measures StartRoot 500 EndRoot cm.
In centimeters, what is the length of an edge of the cube? Round the answer to the nearest tenth.
? centimeters
Answers
Let length, width, and height be s.
Then diagonal of any face would be √( s² + s² ) = √( 2s² )
And we know that it measures √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.
Now we have to solve √( 500 ) = √( 2s² )
Square both sides:
500 = 2s²
Divide both sides by 2:
250 = s²
Take the square root of both sides:
√(250) = s ≈ 15.8113883
Rounding to nearest tenth:
s ≈ 15.8
Final answer: 15.8
Hope this helps.

Make A the subject of the formula r=√А/3
Answers
Answer:a = 9 r^2
Step-by-step explanation:
We need to make a subject of the formula given r = square root a / 3
Given r = √a / 3 -------------1
Now we can find a.
Squaring the given equation 1 we get
So r^2 = (√a / 3)^2
So r^2 = a / 9
