What is the equation of the circle with center (16, - 12) and a radius of 5
Answer:
x^2+y^2-32x+24y+375=0
Step-by-step explanation:
Equation of circle with given centre (h,k) and radius=r is
(x-h)^2+(y-k)^2=r^2
Given centre are=(16, - 12) and radius= 5
So equation of circle=
(x-16)^2+(y- -12)^2=5^2
x^2-32x+256+y^2+24y+144=25
x^2+y^2-32x+24y+375=0

Split 18 into the ratio 1:2
Answer:
6 : 12
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 = 3 parts
Divide by 3 to find the value of one part of the ratio
18 ÷ 3 = 6 ← value of 1 part of the ratio, thus
2 parts = 2 × 6 = 12
1 : 2 = 6 : 12
The number 18 splitted into a ratio of 1 : 2 is 12 and 6.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Slitting in the ratio 1 : 2 can be done in this manner,
{1/(1+2)]×18.
= (1/3)×18.
= 6.
And,
{2/(1+2)]×18.
(2/3)×18.
= 12.

Triangle PQR with coordinates P(3,-4), (6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically. What will
be the coordinates of P'Q'R'?
Answer:
(0, 2), (3, 5) and (3, 0)
Step-by-step explanation:
Since, Points P(3,-4), Q(6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically.
Therefore,
P' (3 - 3, - 4 +6) = P' (0, 2)
Q'(6 - 3, - 1 + 6) = Q'(3, 5)
R'(6 - 3, -6 + 6) = R'(3, 0)
Thus, the coordinates of P'Q'R are (0, 2), (3, 5) and (3, 0).
Answer:
P'(0, 2), Q'(3, 5), R'(3, 0)Step-by-step explanation:
Given
Points P(3,-4), Q(6, -1), R(6, -6) Translation: x -3, y + 6New points:
P'(3 - 3, -4 + 6) = P'(0, 2)Q'(6 - 3, -1 + 6) = Q'(3, 5)R'(6 - 3, -6 + 6) = R'(3, 0)Fifty minus two plus the quantity three divided by six

The figures are similar. Find the missing length.Round to the nearest thousandth
Answer:
The missing x = 0.675 m
Step-by-step explanation:
In similar triangles, the corresponding sides are proportion (means their ratios are equal)
In the given figure
∵ The two triangles are similar
∴ Their corresponding sides are proportion
∵ The sides of lengths 1.8 m and x are corresponding sides
∵ The sides of lengths 8.0 m and 3.0 are corresponding sides
∴ [tex]\frac{1.8}{x}[/tex] = [tex]\frac{8.0}{3.0}[/tex]
→ By using cross multiplication
∴ x × 8.0 = 1.8 × 3.0
∴ 8x = 5.4
→ Divide both sides by 8
∵ [tex]\frac{8x}{8}[/tex] = [tex]\frac{5.4}{8}[/tex]
∴ x = 0.675
→ No rounding because there is no digit after the thousandth digit
∴ x = 0.675 m

What is the slope of the line that passes through the points (-2,6) and (4,10)?
Answer:
The answer is
[tex] \huge \frac{2}{3} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
From the question we have
[tex]m = \frac{10 - 6}{4 - - 2} = \frac{4}{4 + 2} = \frac{4}{6} = \frac{2}{3} \\ [/tex]
We have the final answer as
[tex] \frac{2}{3} \\ [/tex]
