Step-by-step explanation:
The equation of two circles are known, circle A’s equation is (x-3)^2+(y+4)^2=9 and circle B’s equation is (x+4)^2+(y+12)^2=8.
What is the radius of circle A and the radius of circle B.
Answer:
Step-by-step explanation:
The circles are written in standard form. The standard form squares the radius on the right hand side.
Circle A
radius = sqrt(9)
radius = 3
Circle B
radius = sqrt(8)
radius = sqrt(2 * 2 * 2)
radius = 2 sqrt(2)

Answer:
-3x^2+16x+64
Step-by-step explanation:
First, you need to find the area of both areas (the total area and the area of the unshaded part). Let's find the total area.
(x+8)(x+8)=x^2+16x+64
The total area is x^2+16x+64
(2x)(2x)=4x^2
The area of the unshaded part is 4x^2
Now we have to subtract to find the area of the shaded part.
x^2+16x+64-4x^2
-3x^2+16x+64
That is the answer

Find the slope of the line that passes through the points (–4, 2) and (6, 6).
Answer:
Step-by-step explanation:
point P1 (-4,-2) in the form (x1,y1)
point P2(6,6) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
copy and paste the above formula into word pad on your computer for any problem asking about slope :)
m = [ 6-(-2) ] / [ 6-(-4) ]
m = [ 6+2 ] / [ 6+4 ]
m = 8 / 10
m = 4/5
The required slope of the line is 4/5 which passes through the points (–4, 2) and (6, 6).
What is the slope of the line?The slope of line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
The given Line passes through the points (–4, 2) and (6, 6).
Let
x₁ = -4, y₁ = 2
x₂ = 6, y₂ = 6
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Substitute the values in the above formula and solve for m
m = [ 6-(-2) ] / [ 6-(-4) ]
m = [ 6+2 ] / [ 6+4 ]
m = 8 / 10
Reduce the fraction into a simplest form,
m = 4/5
Thus, the required slope of the line is 4/5 which passes through the points (–4, 2) and (6, 6).

The most important thing to remember is: SOH CAH TOA
sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent
So in #1:
We have the angle and hypotenuse and need to solve for the side opposite of the angle. This smells like a sine question.
sin(42)=x/25
this means that x=25sin(42). Plug that into the calculator and get: 16.73.
(Make sure you are in degrees mode)
For #2:
We are given the angle, the opposite side, and have to solve for the adjacent side. Looks like we need the tangent.
tan(75)=12/x
This means that x=12/tan(75). Calculator says: 3.22
For #3:
We have the angle, adjacent, and have to solve for the hypotenuse. This would be a cosine.
cos(36)=19/x
Solve for x: x=19/cos(36). Calculator says: 23.49
For #4:
We have the angle, adjacent side, and need the opposite side. This is another tangent problem.
tan(53)= x/7
Solving for x: x=7tan(53). Calculator says: 9.29

ABC and ADC are triangles. The area of triangle ADC is 52m^2. Work out the length of AB
Answer:
Tthe length of AB is 13.6 cm
Step-by-step explanation:
Step 1: calculate length CD using the area of a triangle
[tex]A = \frac{1}{2} \times (AD \times CD) \times \ sine (D)\\\\52 = \frac{1}{2} \times (12 \times CD) \times \ sine (102)\\\\52 = 6CD \times 0.978\\\\52 = 5.868CD\\\\CD = \frac{52}{5.868} \\\\CD = 8.862 \ cm[/tex]
Step 2: calculate length AC using Cosine rule;
[tex]AC^2 = AD^2 + CD^2 - 2(AD \times CD)cos (D)\\\\AC^2 = 12^2 + 8.862^2 - 2(12 \times 8.862)cos(102)\\\\AC^2 = 222.535 - 2(-22.11)\\\\AC^2 = 222.535 + 44.22\\\\AC^2 = 266.755\\\\AC = \sqrt{266.755} \\\\AC = 16.33 \ cm[/tex]
Step 3: Apply sine rule to calculate length AB;
[tex]\frac{AB}{sin \ 46} = \frac{AC}{sin \ 120} \\\\AB = \frac{sin \ 46 \ \ \times \ \ AC}{sin \ 120} \\\\AB = \frac{sin \ 46 \ \ \times \ \ 16.33}{sin \ 120} \\\\AB = 13.56 \ cm \\\\AB = 13.6 \ cm[/tex]
Therefore, the length of AB is 13.6 cm

The sum of three numbers is 85. The third number is 7 more than the first. The second number is 2 times the third. What are the numbers?
Answer:
16, 46, 23
Step-by-step explanation:
let the first number be x , then the third number is x + 7 and the second is
2(x + 7) = 2x + 14
Sum the numbers and equate to 85
x + 2x + 14 + x + 7 = 85
4x + 21 = 85 ( subtract 21 from both sides )
4x = 64 ( divide both sides by 4 )
x = 16
x + 7 = 16 + 7 = 23
2(x + 7) = 2(16 + 7) = 2(23) = 46
The numbers are 16, 46, 23

which statements are true about the graph of function f?
f(x)= log x
Answer:
I believe the correct answer here is C!
Step-by-step explanation:
The option (A) is correct.
What is graphs of logarithmic function?"The logarithmic function y = log b x is the inverse function of the exponential function y = b x. We can now proceed to graphing logarithmic functions by looking at the relationship between exponential and logarithmic functions".
For the given situation,
[tex]f(x)=logx[/tex]
Plot the graph of [tex]f(x)=logx[/tex] .
From the graph shown below, the region of the graph lies in the domain of { x|0 < x < ∞ } and approaches as 0 as x decreases.
Hence we can conclude that the option (A) is correct.

Answer:
The time taken is 4.79 minutes.
