We are given with a circle and we need to find the equation of the circle , but first let's recall that , the equation of a circle with radius 'r' and centre at (h,k) is given by [tex]{\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}[/tex]
Now , here as as the circle cuts the +ve x-axis at (9,0) . So , it's radius is 9 units or the 2nd way is to measure the distance from centre of the circle to the point where the circle cuts the graph , as the centre is at Origin , so here (h,k) = (0,0) .Which means that the centre is located at the point whose coordinates are (0,0) which is also known as origin . Now , finding the equation of the circle :-
[tex]{:\implies \quad \sf (x-0)^{2}+(y-0)^{2}=(9)^{2}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{x^{2}+y^{2}=81}}}[/tex]
This is the required equation of Circle

45. A square has the same perimeter as a 5 x 11 rectangle. What is the area of the
square?
Answers
Answer:
The area of the square is = 64
Step-by-step explanation:
The perimeter of rectangle = Perimeter of the square
The rectangle has a length (l) of 11 and a width (w) of 5.
The perimeter of a rectangle = 2·l×2·w = 2×11+2×5 = 32
The perimeter of a square = 4·s => Since the perimeter of the rectangle = the perimeter of the square we can find out the side of the square by using the formula in bold.
The perimeter of the square = 4·s = 32
s = [tex]\frac{32}{4}[/tex] = 8
The area of a square is = s×s = s²
The area of the square is = s² = 8² = 64

Please solve for X and find the measure of A.
Answers
Answer:
x = 18°
m∠A = 110°
Step-by-step explanation:
Hello!
Angle A and Angle B are supplementary. Supplementary means they add up to 180°.
Step 1: Solve for x
We can add the two angles together and make it equal to 180° because they are supplementary.
Angle A + Angle B = 180°5x + 20° + 9x - 92° = 180°14x - 72° = 180°14x = 252°x = 18°x = 18°
Step 2: Solve for Angle A
Now that we know the value of x, we can plug it in for the equation of Angle A and solve for the measure of Angle A
Angle A = 5x + 20°Angle A = 5(18°) + 20°Angle A = 90° + 20°Angle A = 110°Angle A = 110°

One factor of the function f(x) = x3 − 6x2 + 11x − 6 is (x − 3)
Find the x-intercepts and the y-intercept of the graph of f(x) without using technology
real confused on this one! please help!!!
Answers
X intercept means a point on the graph which intercepts the x axis
And Y-intercept mean a point on the graph which intercepts the y axis
Meaning at the x intercept the component of y is zero because there is no y on the x axis
And at the y intercept the x component of the coordinate is zero because on the y axis there is no x value
So in finding the y intercept of the graph wherever u see x place zero there (ie x= 0 on the y axis)
So with x = 0
y = (0)3- 6(0)2 + 11(0) - 6
y = -6
Therefore the y intercept is (0,-6) in coordinate form or -6
X-intercept
y = x3 - 6x2 + 11x - 6
After factorization and simplification
y = (x-1)(x-2)(x-3)
On the x axis y= 0
0= (x-1)(x-2)(x-3)
Either x-1=0
x=1
(1,0)
Or x-2=0
x=2
(2,0)
Or x-3=0
x=3 (3,0)
Therefore the x intercepts are 1,2 and 3
And they are expressed in coordinate form as (1,0) ,(2,0) and
(3,0)

x - 2y = 3
14x - 8y = 12
Answers
Answer:
x = 0, y = -3/2
Step-by-step explanation:
Solve the following system:
{-2 y + x = 3 | (equation 1)
{-8 y + 14 x = 12 | (equation 2)
Swap equation 1 with equation 2:
{14 x - 8 y = 12 | (equation 1)
{x - 2 y = 3 | (equation 2)
Subtract 1/14 × (equation 1) from equation 2:
{14 x - 8 y = 12 | (equation 1)
{0 x - (10 y)/7 = 15/7 | (equation 2)
Divide equation 1 by 2:
{7 x - 4 y = 6 | (equation 1)
{0 x - (10 y)/7 = 15/7 | (equation 2)
Multiply equation 2 by 7/5:
{7 x - 4 y = 6 | (equation 1)
{0 x - 2 y = 3 | (equation 2)
Divide equation 2 by -2:
{7 x - 4 y = 6 | (equation 1)
v0 x+y = -3/2 | (equation 2)
Add 4 × (equation 2) to equation 1:
{7 x+0 y = 0 | (equation 1)
{0 x+y = -3/2 | (equation 2)
Divide equation 1 by 7:
{x+0 y = 0 | (equation 1)
{0 x+y = -3/2 | (equation 2)
Collect results:
Answer: x = 0, y = -3/2
