In the diagram, a circle centered at the origin, a right triangle, and the Pythagorean theorem are used to derive the equation of a circle, x2 + y2 = r2.
If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle, which could represent the equation of the new circle?
A: (h + x)2 + (k + y)2 = r2
B: (x – h)2 + (y – k)2 = r2
C: (k + x)2 + (h + y)2 = r2
D: (x – k)2 + (y – h)2 = r2
Answer:
B
Step-by-step explanation:
[tex]\textsf{Let}\:(x_1,y_1)=(h,k)[/tex] → new center of the circle
[tex]\textsf{Let}\:(x_2,y_2)=(x,y)[/tex] → point on the circle
Therefore, the radius (r) is the distance between (x, y) and (h, k)
Use the distance formula:
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=d[/tex]
[tex]\implies \sqrt{(x-h)^2+(y-k)^2}=r[/tex]
Square both sides:
[tex]\implies (x-h)^2+(y-k)=r^2[/tex]
Answer:
Option B
Step-by-step explanation:
Then we have to use distance formula to derive it
√(x-h)²+(y-k)²=r(x-h)²+(y-k)²=r²Option B is correct

Answer:
5 for both.
Step-by-step explanation:
Multiplying exponents rule with like bases;
Add powers with like bases.
So, if we look at x to the power of the blank multiplied by x to the power of 5, we know that 5 added to that unknown/blank power would equal in 10(using the multiplication of exponents rule), because in the results it says x^10.
Thus,
x to the power of __ · x to the power of 5 = x to the power of 10
And, 5 would make a solution for the blank, because;
x to the power of 5 · x to the power of 5 = x to the power of 10, which is true because their exponents added together would be 10 → (5 + 5).
Now, if we look at y to the power of 3 multiplied by y to the power of the blank, we know that 3 added to the unknown/blank power would equal in 8(using the multiplication of exponents rule) because in the results says y^8.
Thus,
y to the power of 3 · y to the power of __ = y to the power of 8
And, 5 would make a solution for the blank, because;
y to the power of 3 · y to the power of 5 = y to the power of 8, which is true because their exponents added together would be 8 → (3 + 5).
Therefore, 5 would be the answer.Overall you're basically just multiplying all those exponents together.

Fatoumata owns a small business selling ice-cream. She knows that in the last week 13 customers paid cash, 39 customers used a debit card, and 5 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a debit card as a percent to the nearest whole number.
Answer:
40
Step-by-step explanation:
40 because 39 will round up to 40 by 1
The probability in percentage that the next customer will pay with a debit card will be 68.42%.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
She knows that in the last week, 13 customers paid cash, 39 customers used a debit card, and 5 customers used a credit card.
The probability that the next customer that will pay with a debit card will be given as,
P = 39 / (13 + 39 + 5)
P = 39 / 57
P = 0.6842 or 68.42%

Answer:
B
Step-by-step explanation:
Answer:
x=75
Step-by-step explanation:
2 * ln (e ^ ln (2x)) - ln (e ^ ln (10x)) = ln (30)
Apply exponent rules
2 * ln (2x) - ln (10x) = ln (30)
Apply log rules
2 * ln (2x) - ln (10x) = ln (30)
Apply log rule: logc(ab) = logc(a) +logc (b)
Apply exponent rules
2 * ln (2x) - ln (10x) = ln (30)
Apply log rules
2 * ln (2x) - ln (10x) = ln (30)
Apply log rule: logc(ab) = logc(a) + logc (b)
ln (2x) = ln (2) + ln (2)
2(ln (2) + ln (x)) - ln (10x) = ln (30)
Apply log rule: logc(ab) = logc(a) + logc (b)
ln (10x) = ln (10) + ln (x)
ln (2x) = ln (2) + ln (2)
2(ln (2) + ln (x)) - ln (10x) = ln (30)
Apply log rule: logc(ab) = logc(a) + logc (b)
ln (10x) = ln (10) + ln (x)
Apply log rule: logc(ab) = logc(a) + logc (b)
ln (10x) = ln (10) + ln (x)
2(ln(2)+ln(x))-(ln(10)+ln(x))=]
Expand 2(ln(2) +ln(x)
ln (x) + 2 * ln (2) - ln (10) = ln (30)
Subtract 2 * ln (2) - ln (10) from both sides
In(x) + 2ln(2) - In(10) - (2ln(2) - In
Simplify
ln (x) = ln (30) - 2 * ln (2) + ln (10)
Simplifify ln (30) - 2 * ln (2) + ln 10
ln (x) = ln (75)
Apply log rule: If logb(f(x)) = logb (g(x)) then f(x) = g(x)
x = 75
Verify Solutions: X = 75
Check the solutions by plugging them
into 2 * ln (2x) - ln (10x) = ln (30) Remove the ones that don't agree with the equation.
Plug in x =75
2 * ln (2 * 75) - ln (10 * 75) = ln (30)
2 * ln (2 * 75) - ln (10 * 75) = ln (30)
ln (30) = ln (30)

What is the volume of the figure below if a = 8 units and b = 6 units?
A.
536 cubic units
B.
704 cubic units
C.
256 cubic units
Answer:
704 cubic units
Step-by-step explanation:
First let's calculate the volume of the cube. The formula to calculate the volume of a cube is V = a^3, a being the edge length of the cube. So we need to cube the value of a, which is 8. 8 cubed is 512 cubic units.
Now we need to calculate the volume of the triangular prism. The formula to calculate the volume of a cube is V = 1/2b * a * h, a being the side edge length of the prism, b being the height of the triangular side, and h being the base edge length of the triangular side, if that makes any sense (easier to explain visually). h and a are equal to the given a, which is 8 in this case. And b in the formula is equal to b in the given problem. So we substitute the values into the formula: V = (1/2*6) * 8 * 8 = 3 * 64 = 192 cubic units.
Now we take the sum of both of the figures:
512 + 192 = 704 cubic units.
The length of a rectangle is five time it’s width. If the perimeter of a rectangle is 84ft, find its area
Answer:
Area = 245 ft
(Width
Step-by-step explanation:
l = 5w
Where l is length and w is width.
We also know that the perimeter is 84 ft, so:
2l + 2w = 84
Now we can plug in 5w for l since we found the equality earlier:
2(5w) + 2w = 84
and then solve for w:
10w + 2w = 84
12w = 84
w = 7
so
l = 5 × 7
l = 35
The length is 35 and width is 7 so
the area of the rectangle is
[tex]7 \times 35 = 245ft [/tex]

OR
5x + x - 6 = 90
x = 16
m
Angle1 = 80°
mAngle2 = 10°
Step-by-step explanation:
Angle 1 + Angle 2 adds up to 90°. The tiny square in the corner of the image shows you that the whole thing is 90°.
So write the equation base on that.
5x + x - 6 = 90
Combine like terms(add the x's)
6x - 6 = 90
Add 6.
6x = 96
Divide by 6.
x = 16
Fill in 16 for x to find the measures of the angles.
Angle 1 = 5x
= 5(16)
= 80°
Angle 2
= x - 6
= 16 -6
= 10°
And 80°+ 10° is 90° so that's a good check. Hope this helps!

How is the scale factor, surface area ratio and volume ratio related?
If two solids are similar with a scale factor of a/b, then the surface areas are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^2[/tex].
If two solids are similar with a scale factor of a/b, then the volumes are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^3[/tex].
What are the area and volume of similar solids?Two shapes are similar if all their corresponding angles are congruent and their corresponding sides are proportional.
Two solids are similar if they are the same type of solid and their corresponding radii, heights, base lengths, widths, etc. are proportional.
When two shapes are similar in two dimensions, the ratio of their areas is the square of the scale factor.
A comparable relationship holds in three dimensions as well.
Surface Area Ratio: If two solids are similar with a scale factor of a/b, then the surface areas are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^2[/tex].
Volumes of Similar Solids; Just like surface area, volumes of similar solids have a relationship that is related to the scale factor.
