Step-by-step explanation:
Hey there!
The points P1(3,-3) and midpoint is (-2,1). Let (X,y) be the end point.
Note: Find through using midpoint formula.
midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )
Put all values.
(\frac{X+3}{2},\frac{-3+y}{2})
Since they are equal, equating with it's corresponding components.
\frac{3 + x}{2} = - 2
-2 = 3 + x
-4 -3= x
Therefore, X= -7.
Now,
[tex] \frac{ - 3 + y}{2} = 1[/tex]
[tex] - 3 + y = 2[/tex]
Therefore, y= 5
Therefore, the other end point is (3,5).

A mailman (M) is located 450 feet from a Post Office (P). The mailman notices a bird (B) flying at a 42° angle of elevation from his line of sight. How high (h) is the bird flying over the Post Office? Round to the nearest whole number. (Show all work)
Answer:
We can use the sine law to find h. First, we determine the angle between the line of sight and h:
180 - 90 - 39 = 51 degrees
The sine law states that the ratio of one triangle's angle to the opposite side's length is the same as another angle to its opposite side's length, so we can solve for h as follows:
h/sin(39) = 500/sin(51)
h = 500*sin(39)/sin(51)
When we round to the nearest whole number, we get h = 405 ft.

Answer: 33
Step-by-step explanation:
AN Calculators can be purchased for the upcoming end-of-course exam. The revenue function can be modeled as RAN (3) = (25 10x) (300 - 36x) where x is the price of the calculator. MN Calculators can also be purchased for the upcoming exam. The revenue function can be modeled as RuN (x) = (100 20x) (100 - 12x) where x is the price of the calculator. Determine the price of each calculator where the revenue of AN Calculators and MN Calculators are the same.
The revenue functions of the calculator companies is the difference between their cost and profit functions
The price of each calculator when the revenues of AN Calculators and MN Calculators are the same is $2.5
How to determine when the prices are the sameThe revenue functions are given as:
RAN (x) = (25 + 10x) (300 - 36x)
RMN (x) = (100+ 20x) (100 - 12x)
When the prices are the same, we have:
RAN (x) = RMN (x)
So, we have:
[tex](25 + 10x) (300 - 36x) = (100+ 20x) (100 - 12x)[/tex]
Divide through by 20
[tex](5 + 2x) (75 - 9x) = (10+ 2x) (50 - 6x)[/tex]
Using a graphing calculator, we have the following value of x
x = 2.5
Hence, the price of each calculator when the revenues of AN Calculators and MN Calculators are the same is $2.5

If r= 9 units and x = 4 units, then what is the volume of the cylinder shown above?
Answer:
Volume of the cylinder is. 1017.36
Step-by-step explanation:
[tex]V=\pi r^2h[/tex] is the area of a cylinder.
Let's plug in our values.
-----
3.14 = pi
9 = radius
x = height
-----
V = (3.14)(9)^2(4)
V = (3.14)(81)(4)
V = (3.14)(324)
V = 1017.36
What is the solution to the system of equations below?
x + 3 y = 15 and 4 x + 2 y = 30
(7 , 2)
(2, 7)
(4, 3)
(3, 4
Answer:
Step-by-step explanation:
x + 3y = 15 ×4
4x + 2y = 30 ×1
4x + 12y = 60
- - -
4x + 2y = 30
10y = 30
y = 30/10
y = 3
To solve for x, substitute y = 3 into any of the equations
x + 3(3) = 15
x + 9 = 15
x = 15 - 9
x = 6
(6,3)
This should be the answer but I don't see that in the options u listed, so I don't know what else it should be.
The required solution to the system of equations is (x, y) = (6, 3).
Given the system of equations:
x + 3y = 15
4x + 2y = 30
Multiply Equation 1 by 2 to make the coefficients of y in both equations equal:
2(x + 3y) = 2(15)
2x + 6y = 30
Subtract Equation 2 from the modified Equation 1 to eliminate the variable x:
(2x + 6y) - (4x + 2y) = 30 - 30
-2x + 4y = 0
Divide the resulting equation by 2 to simplify it further:
-x + 2y = 0
Now, we have a new equation:
3) -x + 2y = 0
Add the new Equation 3 to the original Equation 1 to eliminate the variable x again:
(x + 3y) + (-x + 2y) = 15 + 0
5y = 15
Solve for y:
y = 15 / 5
y = 3
Now, substitute the value of y back into Equation 1 to find x:
x + 3(3) = 15
x + 9 = 15
x = 15 - 9
x = 6

Sallie Woo worked these hours last week: Monday, 10; Tuesday, 8 1/4; Wednesday, 9 1/2; Thursday, 6; Friday, 8; Saturday, 5. Sallie is paid $11.40 per hour for regular hours, time and a half for overtime during the week, and double time for weekend hours. If Sallie works on an 8-hour day basis, what was her pay for the week?
Answer:
Her pay for the week= $ 611.325
Step-by-step explanation:
Sallie is paid $ 11.40 per hour for regular hours.
The total regular hours worked during the week are
Monday + Tuesday + Wednesday + Thursday+ friday = 8 + 8+ 8+6+8= 38 hours
She works overtime during the week
Monday + Tuesday + Wednesday = 2+ 1/4+ 1 1/2= 2+ 1/4 + 3/2
= 8 +1+ 6/4=15/4 = 3 3/4 hours
Over the weekend she works five hours .
So the total pay would be
$ 11.40( 38 ) + $ 11.40( 1.5) ( 15/4) + $ 11.40 ( 2) ( 5)
= 433.2 + 64.125 + 114.0
= $ 611.325
