A circle is centered at (5, −9) and has a radius of 12. Which of the following is the equation for this circle?

Answers

Answer:

[tex]\boxed {\boxed {\sf (x-5)^2+(y+9)^2=144}}[/tex]

Step-by-step explanation:

The standard form for the equation of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

where (h,k) is the center of the circle and r is the radius.

For this circle, the center is (5, -9) and the radius is 12. Therefore:

[tex]h= 5 \\k= -9 \\r=12[/tex]

Substitute the values into the formula.

[tex](x-5)^2+(y-(-9))^2=(12)^2[/tex]

Distrubute the -1 into the -9.

-(-9)= -1*-9= 9

[tex](x-5)^2+(y+9)^2=(12)^2[/tex]

Solve the exponent.

(12)²= 12*12=144

[tex](x-5)^2+(y+9)^2=144[/tex]

The equation for the circle with a center (5,-9) and radius of 12 is (x-5)²+(y+9)²=144

Based on the calculations, the equation of this circle in standard form is equal to (x - 5)² +(y + 9)² = 144.

The equation of a circle.

Mathematically, the standard form of an equation of a circle is given by;

(x - h)² +(y - k)² = r²

Where:

h and k represents the coordinates at the center.r is the radius of a circle.

Given the following data:

Coordinates (h, k) = (5, -9).Radius = 12.

Substituting the given parameters into the formula, we have;

(x - 5)² +(y - (-9))² = 12²

(x - 5)² +(y + 9)² = 144

5. In the right triangle shown below, the length of side AB is x, the length of side BC is x + 2, and the length of the
hypotenuse AC is x + 4. Use this information to find the length of each side. (Use the Pythagorean theorem to get
an equation, and solve for x.)

I need an answer quick!!!
It’s from the problem set to lesson 17 M.1

Answers

Answer:

[tex]AB = 6[/tex] [tex]BC = 8[/tex] [tex]AC = 10[/tex]

Step-by-step explanation:

The picture of the triangle is missing.

Given

[tex]AC = x + 4[/tex]

[tex]BC = x + 2[/tex]

[tex]AB = x[/tex]

Required

Find x

When Pythagoras theorem is applied, we have:

[tex](AC)^2 = (BC)^2 + (AB)^2[/tex]

This is so, because AC is the hypotenuse

So, we have:

[tex](x+4)^2 = (x+2)^2 + x^2[/tex]

Open brackets

[tex]x^2 + 4x + 4x + 16 = x^2+2x + 2x + 4 + x^2[/tex]

[tex]x^2 + 8x + 16 = x^2+4x + 4 + x^2[/tex]

Collect Like Terms

[tex]x^2 -x^2 - x^2 + 8x -4x + 16 - 4 = 0[/tex]

[tex]- x^2 + 4x + 12 = 0[/tex]

Expand:

[tex]- x^2 + 6x -2x+ 12 = 0[/tex]

Factorize:

[tex]-x(x -6) -2(x- 6) = 0[/tex]

[tex](-x -2)(x- 6) = 0[/tex]

Split

[tex]-x - 2 = 0[/tex] or [tex]x - 6 = 0[/tex]

[tex]-x = 2[/tex] or [tex]x = 6[/tex]

[tex]x =-2[/tex] or [tex]x = 6[/tex]

Because [tex]BC = x + 2[/tex] and [tex]AB = x[/tex]

[tex]x =-2[/tex] can not be considered.

Hence:

[tex]x = 6[/tex]

Substitute 6 for x in

[tex]AC = x + 4[/tex]

[tex]BC = x + 2[/tex]

[tex]AB = x[/tex]

[tex]AC = 6 + 4[/tex]

[tex]AC = 10[/tex]

[tex]BC = 6 + 2[/tex]

[tex]BC = 8[/tex]

[tex]AB = 6[/tex]

Is this graph and example of a sin or cos graph?

Answers

this is a sin graph im pretty sure

Answer:

Sine

I think

Step-by-step explanation:

The graph of the cosine is the darker curve; note how it's shifted to the left of the sine curve. The graphs of y = sin x and y = cos x on the same axes. . .. You probably noticed that these cofunction identities all use the difference of angles, but the slide of the sine function to the left was a sum.

The sine of the angle = the length of the opposite side. the length of the hypotenuse.

The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

The given equations are :

7v-3/2=5 ....(1)

14v-3=15 ....(2)

Taking equation (1) first,

7v-3/2=5

Adding 3/2 to both the sides.

7v-3/2+3/2=5+3/2

7v = 6.5

v = 0.928

Taking equation (2).

14v-3=15

Adding 3 to both sides.

14v-3+3=15+3

14v=18

v = 1.285

So, the values of v in both equations ar not the same. It means two equations are not equivalent.

Find a number, twice of which decreased by 7 gives 65.

Answers

Answer:

Number = 36

Step-by-step explanation:

Given that,

A number twice of which decreased by 7 gives 65.

Let the number be x.

Twice of the number is 2x.

ATQ,

2x - 7 = 65

We can solve the above equation.

Adding 7 both sides.

2x-7+7 = 65 +7

2x = 72

x = 36

So, the required number is 36.
