Answer:
x² + y² - 12x - 6y + 29 = 0
Step-by-step explanation:
Simplifying the equation using (a + b)² = a² + 2ab + b²:
(x - 6)² + (y - 3)² = 16
⇒ [x² - 2(x)(6) + 6²] + [y² - 2(y)(3) + 3²] = 16
⇒ [x² - 12x + 36] + [y² - 6y + 9] = 16
⇒ x² - 12x + 36 + y² - 6y + 9 = 16
General form of a circle = x² + y² + Cx + Dy + E = 0
Before we reorganize the equation in general form, we need to have the R.H.S as 0. For that, we need to subtract 16 both sides.
Subtract 16 both sides:
⇒ x² - 12x + 36 + y² - 6y + 9 = 16
⇒ x² - 12x + 36 + y² - 6y + 9 - 16 = 16 - 16
⇒ x² - 12x + 20 + y² - 6y + 9 = 0
Reorganizing the equation in general form:
x² - 12x + 20 + y² - 6y + 9 = 0
⇒ x² - 12x + 20 + y² - 6y + 9 = 0
⇒ x² + y² - 12x + 20 - 6y + 9 = 0
⇒ x² + y² - 12x + 20 - 6y + 9 = 0
⇒ x² + y² - 12x - 6y + 20 + 9 = 0
⇒ x² + y² - 12x - 6y + 29 = 0
Thus, the equation in general form is x² + y² - 12x - 6y + 29 = 0.
What is the circumference
Please answer ASAP! I am very confused. Please explain steps if possible.
Answer:
943 exponent 14
Step-by-step explanation:
The question deals with indices(exponents). Therefore,all laws of indices related to the question must be applied to clearly solve and understand the question.
so,(943 exponent 78 · 943 exponent 1)/943 exponent 65
· means multiplication so simply,(943 exponent 78 × 943 exponent 1)/943 exponent 65
The laws of indices clearly state that, when two indices of the same base are multiplying, you add their exponents and when dividing,you subtract their exponents.
As all the indices have the same base which is "943", we can quickly add & subtract the exponents.
(Leaving base out of calculation now to make it easier to directly deal with exponents)
(78+1)-65(From the rules)
79-65=14,which means 943 exponent 14
∴The answer is 943 exponent 14

What is the area and circumference of the circle? diameter = 12 cm
Answer:
Circumference = 7.68 cm
Area = 113.04 cm²
Step-by-step explanation:
First, let us find the radius of the given circle.
d = 2r
r = d / 2
r = 12 / 2
r = 6 cm
And now, let us find the circumference of the circle using the below formula.
C = 2 π r
C = 2 × 3.14 × 6
C = 37.68 cm
And now let us find the area of the circle using the below formula.
A = π r²
A = 3.14 × 6 × 6
A = 113.04 cm²

Mike is building storage boxes. Each box will have a length of 5 feet, a width of 412 feet, and a height of 312 feet. A pint of paint covers 50 square feet.
How many pints of paint does Mike need to buy in order to paint 4 boxes?
9 pints
7 pints
6 pints
5 pints
Answer:
Step-by-step explanation:
The question contains typos as I believe the boxes should be 5x4.2x3.2 in dimensions instead.
Assuming that and all 6 faces of each storage boxes will be painted, the surface area of each box is:
= (5*4.2*2) + (4.2*3.2*2) + (3.2*5*2)
= 100.88 square feet
4 boxes will have a total surface area of
100.88*4
= 403.52 square feet
Each pint of paint covers 50 square feet so a total of
403.52/50 = 8.07 or
9 pints is needed.

What is the center and radius of the circle given by x2 + y2 - 10x - 12y + 24 = 0?
Answer:
centre (5, 6 ) , r = [tex]\sqrt{37}[/tex]
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r the radius
given
x² + y² - 10x - 12y + 24 = 0 ( collect x and y terms together and subtract 24 from both sides )
x² - 10x + y² - 12y = - 24
using the method of completing the square
add ( half the coefficient of the x / y terms)² to both sides
x² + 2(- 5)x + 25 + y² + 2(- 6)y + 36 = - 24 + 25 + 36
(x - 5)² + (y - 6)² = 37 ← in standard form
with centre (h, k ) = (5, 6 ) and r = [tex]\sqrt{37}[/tex]
What is the area of the quadrilateral
Answer:
Or you could also find the area of 2 triangles and one rectangle.
Area of a triangle = bh/2
1st triangle = 6 x 2 = 12
12 ÷2 = 6
2nd triangle = 6x2= 12 ÷ 2 = 6
Area of a rectangle
A=bh
b = 4
h= 6
6x4=24
Now add all the areas to find out the area of the shape, so
6+6+24 =

Find the measure of the arc or angle indicated
Answer:
D) 130
Step-by-step explanation:
So there are three arc sections in this problem,
The first one is given: 158
To find the arc between S and R, you can use the angle of point T and double it.
So:
36 * 2 = 72
The second arc is 72
Now for the one that they want you to find, you have to add the two arcs that you have and substract it from 360, which is the angle of a whole circle
Like so:
360 - (158 + 72) = 130

Answer:
[tex]f(x) = 2000 * 1.05^x[/tex]
Step-by-step explanation:
The key to this question is interpreting the graph and then modelling it into an exponential function.
You are given 2 key characteristics of this graph. 1 characteristic being that it intercepts the y-axis at (0,2000), and another characteristic being that it goes through the point (1,2100)
Now refer to the standard form of an exponential function.
[tex]y = a * b^x[/tex]
Since you know that when x = 0, y = 2000, a must be 2000. Because [tex]b^0 = 1[/tex], 2000 * 1 = 2000
So you got your a value. Sub it into the equation and now you got.
[tex]y = 2000 * b^x[/tex]
You still need to solve for b, so this is where you do some algebra. Pick your key point, (1,2100), sub in those values for x and y, and solve for b.
[tex]2100 = 2000 * b^1\\\frac{2100}{2000} = b\\ 1.05 = b[/tex]
Now you have your a and b values. Now you can express using a function:
[tex]f(x) = 2000 * 1.05^x[/tex]

much interest will she pay and what is the total amount she will have to
pay back? (Principal and interest).
The total amount accrued, principal plus interest, from simple interest on a principal of $25,000.00 at a rate of 15% per year for 6 years is $47,500.00.
Answer:
I = $22,500.00
A = $47,500.00
Simple interestGiven Data
Principal = $25000
Rate = 15%
Time = 6 years
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 15%/100 = 0.15 per year.
Solving our equation:
A = 25000(1 + (0.15 × 6)) = 47500
A = $47,500.00
I = A - P = $22,500.00

What are trigonometric identities?
Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
we need to first know the signs of the trigonometric functions in each of the 4 quadrants going in an anti-clockwise direction.
In the first quadrant, the cot, sin, cos and tan are all positive.
In the second quadrant going anti-clockwise, only sine is positive.
In the third quadrant going anti-clockwise, only tangent is positive.
In the fourth quadrant going anti-clockwise, only cosine is positive.
We are told that the
sinθ < 0 and cos θ > 0.
This means that sine is negative and cosine is positive.
Looking at the rule, it is clear that the angle is in the fourth quadrant.

If you want to Add then,
3/5 + 1/2 = 6 + 5/5 × 2 = 11/10 or 1.1
If you want to subtract then,
3/5 – 1/2 = 6 – 5/5 × 2 = 1/10 or 0.1
If you want to Divide then,
3/5 ÷ 1/2 = 3/5 × 2/1 = 6/5
