Answer:
A (-4, 1)B (2, 5)Step-by-step explanation:
The current endpoints are ...
V = (-9, 2)
W = (-3, 6)
Put each of these in the translation formula to see where the image points are.
(x, y) ⇒ (x+5, y-1)
(-9, 2) ⇒ (-9+5), 2-1) = (-4, 1) . . . . point V ⇒ V'
(-3, 6) ⇒ (-3+5, 6-1) = (2, 5) . . . . . point W ⇒ W'
The new end points are (-4, 1) and (2, 5), matching choices A and B.

2. 4x - 2y = -6
-6x + 2y = 2
Answer:
x = 2, y =7
Step-by-step explanation:
4x - 2y = -6
-6x + 2y = 2
Add the equations together
4x - 2y = -6
-6x + 2y = 2
-----------------------
-2x = -4
Divide each side by -2
-2x/-2 = -4/-2
x = 2
now find y
-6x+2y =2
-6(2) +2y =2
-12+2y =2
Add 12 to each side
-12+12+2y = 2+12
2y =14
Divide by 2
2y/2 =14/2
y =7
A sector with an area of 26pie cm^2 has a radius of 6 cm. What is the central angle measure of the sector in radians?
Answer:
The central angle measure of the sector in radians is [tex]\theta=\frac{13}{9}[/tex].
Step-by-step explanation:
A sector of a circle is the portion of a circle enclosed by two radii and an arc. It resembles a "pizza" slice.
The area of a sector when the central angle is in radians is given by
[tex]A=(\frac{\theta}{2})\cdot r^2[/tex]
where
r = radius
θ = central angle in radians
We know that the area of the sector is [tex]26 \:cm^2[/tex] and the radius is 6 cm. Applying the above formula and solving for the central angle ([tex]\theta[/tex]) we get that
[tex]26=(\frac{\theta}{2})\cdot (6)^2\\\\\left(\frac{\theta}{2}\right)\left(6\right)^2=26\\\\\frac{\frac{\theta}{2}\cdot \:6^2}{36}=\frac{26}{36}\\\\\frac{\theta}{2}=\frac{13}{18}\\\\\theta=\frac{13}{9}[/tex]

How do you make a decimal into a fraction?
Answer:
Step 1: Write down the decimal divided by 1, like this: decimal 1.
Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
Step 3: Simplify (or reduce) the fraction.

Find S9, the sum of the geometric series to the 9th term, in which a3=3.645 and a8=15
Answer:
The sum of the first nine terms of the sequence is 74.44.
Step-by-step explanation:
Geometric sequence concepts:
The nth term of a geometric sequence is given by the following equation.
[tex]a_{n+1} = ra_{n}[/tex]
In which r is the common ratio.
This can be expanded for the nth term in the following way:
[tex]a_{n} = a_{1}r^{n-1}[/tex]
In which [tex]a_{1}[/tex] is the first term.
Or even:
[tex]a_{n} = a_{m}r^{n-m}[/tex]
The sum of the first n terms of a geometric sequence is given by:
[tex]S_{n} = \frac{a_{1}(1 - r^{n})}{1 - r}[/tex]
Finding the common ratio:
[tex]a_{3} = 3.645, a_{8} = 15[/tex]
[tex]a_{n} = a_{m}r^{n-m}[/tex]
[tex]a_{8} = a_{3}r^{8-3}[/tex]
[tex]a_{3}r^{5} = a_{8}[/tex]
[tex]3.645r^{5} = 15[/tex]
[tex]r^{5} = \frac{15}{3.645}[/tex]
[tex]r = \sqrt[5]{\frac{15}{3.645}}[/tex]
[tex]r = 1.327[/tex]
Finding the first term:
[tex]a_{3} = a_{1}r^{2}[/tex]
[tex]a_{1} = \frac{a_{3}}{r^{2}}[/tex]
[tex]a_{1} = \frac{3.645}{(1.327)^{2}}[/tex]
[tex]a_{1} = 2.07[/tex]
Sum of the first nine terms:
[tex]S_{9} = \frac{2.07*(1 - (1.327)^{9})}{1 - 1.327} = 74.44[/tex]
The sum of the first nine terms of the sequence is 74.44.
Answer:
S₉ = 9.84
Step-by-step explanation:
In a geometric series, the general formula for nth term is:
an = a₁rⁿ⁻¹
where,
an = nth term
a₁ = first term
r = common ratio
From this formula, we have:
a₃ = a₁r² = 3.645 --------- equation (1)
a₈ = a₁r⁷ = 15 ----------- equation (2)
dividing both of these equations, we get:
a₁r⁷/a₁r² = 15/3.645
r⁵ = 4.115
r = (4.115)^1/5
r = 1.33
Now, put this value in equation (1), we get:
a₁(1.33)² = 3.645
a₁ = 0.27
Now, the formula for the sum of geometric series upto nth term is:
Sn = a₁(rⁿ - 1)/(r - 1)
therefore,
S₉ = (0.27)(1.33⁹ - 1)/(1.33 - 1)
S₉ = 9.84
Multiply and write in standard form.

There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?
Answer:
There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 plus $4 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?
Step-by-step explanation:
The correct situation is the third one, this is because the expression we have is:
[tex]30+4x=70+2x[/tex]
let's take the left side as the charge of the company limo A, and the left side as the charge of limo B.
Since 'x' is the number of people, the left side tells us that limo A charges $4 per person (hence the 4x) and adds an additional $30 (hence the 30 added on the left side).
And the right side tells us that limo B charges $2 per person (hence the 2x) and adds an additional $70 (hence the 70 added on the right side).
And since we have an equal sign this means that the expression represents the number of people that can ride and will pay an equal amount in each company.
This is the situation that the third option describes:
There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 plus $4 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?
the circumference of a circle is 107.81 yards. Find the diameter of the circle to the nearest tenth
Answer:

Determine the intercepts of the line.
9x-7y=14
Answer:
The intercepts of the line: 9x - 7y = 14
For x-intercept, in this case: y = 0, => 9x = 14 => x = 14/9
=> x-intercept (14/9, 0)
For y-intercept, in this case: x = 0, => -7y = 14 => y = -2
=> y-intercept (0, -2)

The volume of the mold is 186 cubic feet concrete is sold by cubic yard how many cubic yards of concrete will I need to fill mold
Answer:
Volume of the mold is [tex]6.93\ \text{yards}^3[/tex].
Step-by-step explanation:
The volume of the mold is 186 cubic feet concrete. It is to be sold by cubic yard. It means that we need to convert cubic feet to cubic yard.
1 feet = 0.334 yards
[tex]186\ \text{feet}^3=186\times (0.334\ \text{yards})^3\\\\V=6.93\ \text{yards}^3[/tex]
So, the volume of the mold is [tex]6.93\ \text{yards}^3[/tex].

Answer: A) DE = 24 yd and EF = 10 yd
Step-by-step explanation:
Shape EFD is just a dilate of 2, meaning BCA x 2.
13 x 2 = 26
12 x 2 = 24
5 x 2 = 10
Therefore, DE = 24 yd and EF = 10 yd
I hope this helps!
Answer:
DE = 24, EF = 10
Step-by-step explanation:
We can use ratios to solve
13 ft 12 ft
---------- = -----------
26 ft x ft
Using cross products
13x = 12*26
Divide each side by 13
13x/13 = 12*26/13
x = 24
13 ft 5 ft
---------- = -----------
26 ft y ft
Using cross products
13y = 5*26
Divide each side by 13
13y/13 = 5*26/13
y = 10
write an equation in point-slope form for the line that has a slope of 15 and contains the point (2,−9).
Answer:
y +9 = 15(x -2)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . for slope m and point (h, k)
Here, you are given m=15 and (h, k) = (2, -9). Putting these values into the form gives the equation ...
y +9 = 15(x -2)
Carl earned grades of 62, 78, 59, and 89 on four math tests.
What is the mean of his grades?
A. 68.5
B. 70
C. 72
D. 74
E. 75.5
Answer:
Mean, m = 72
Step-by-step explanation:
It is given that, Carl earned grades of 62, 78, 59, and 89 on four math tests.
It is required to find the mean of his grades.
Mean of a data is given by :
[tex]m=\dfrac{\text{sum of observations}}{\text{total no of observations}}[/tex]
Sum of observations is 62 + 78 + 59 + 89 = 288
Total no of observations are 4
So, mean of his grades is :
[tex]m=\dfrac{288}{4}\\\\m=72[/tex]
So, the mean of his grades is 72.
Option C is correct. If Carl earned grades of 62, 78, 59, and 89 on four math tests, the mean of his grades is 72
Mean is the average of the given data. It is expressed mathematically as:
[tex]\overlibe x=\frac{\sum x}{N}[/tex]
[tex]\sum x[/tex] is the sum of the variables
N is the total test taken
[tex]\sum x = 62 + 78 + 59 + 89\\\sum x = 288\\\\N = 4[/tex]
Substitute the resulting values into the mean formula:
[tex]\overline x = \frac{288}{4}\\ \overline x =72[/tex]
This shows that the mean of his grades is 72
