The constant sum for the ellipse with the foci (-5,5) and (0,7) and the point (0,5) is 7

The foci of the ellipse are given as:

F1(−5, 5) aF2(0, 7)

The point is then given as:

Point (0, 5)

Calculate the distance between each focus and the point using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

[tex]F_1 = \sqrt{(-5-0)^2 + (5-5)^2}[/tex]

Evaluate

[tex]F_1 = 5[/tex]

Also, we have:

[tex]F_2 = \sqrt{(0-0)^2 + (7-5)^2}[/tex]

Evaluate

[tex]F_2 = 2\\[/tex]

The constant sum is then calculated using:

Constant sum = F1 + F2

So, we have:

Constant sum = 5 + 2

Evaluate

Constant sum = 7

Hence, the constant sum is 7

Step-by-step explanation:

For a RIGHT triangle   tan A = opposite side / adjacent side

tan A = 12/10

arctan ( tan A) = A = arctan (12/10) = 50.19 degrees

Answer:

A and C.

Step-by-step explanation:

We are given that: "The square of a number (which we can call x) is three less than four times the number."

In other words:

[tex]\displaystyle x^2 = 4x - 3[/tex]

Hence solve for x by isolating the equation and factoring:

[tex]\displaystyle \begin{aligned} x^2 - 4x + 3 & = 0 \\ \\ (x-1)(x-3) & = 0 \\ \\ x & = 1 \text{ or } x = 3 \end{aligned}[/tex]

In conclusion, our answers are A and C.

Answer:

Average per floor = 162 dollars.

Step-by-step explanation:

Remark

First find the number of floors

Then make a total   income received from those floors.

Then divide the total income by the number of floors, to get the average

Number of floors

Total number of floors = 6 + 2 + 1 = 9 floors

Total income

Total income = cost per floor * the number of floors.

Total income

6 * 140 =  840

2 * 220 = 440

1 * 178   = 178

Total    = 1458

Average income / Floor

Average income / Floor = Total amount / number of floors

Average Income / Floor = 1458 / 9 =  162

Answer: 11 cm

Step-by-step explanation:

        Let x be the length of one of the other sides. If two are equal, then they both will be 2x.

       Then one side is equal to 14 cm.

       All the sides added together, the perimeter, is equal to 36 cm.

      We will take the numbers we pulled from the problem, create an equation, and solve for x.

36 cm = 14 cm + 2x

22 cm = 2x

11 cm = x

          The length of each of the two other sides is 11 cm.

An angle bisector divides the angle measure into two equal parts. In triangle ABC, B is the point at which the angle lies.

Step-by-step explanation:

Picture segment BD drawn from point B of tri.ABC where it connects to segment AC, creating point D. Now picture E drawn on the newly created segment DC where it connects to point B and down to point C. Here's a drawing to better show this:

It's bisecting the bisected angle ABC. So, 140/2 = 70, and 70/2 = 35.

Answer:

w=39 degrees and r=51 degrees

Step-by-step explanation:

The sum of the angles in a triangle should equal 180 degrees. Knowing this we take (38+103) - 180 = 39. Since opposite angles are always congruent, we can conclude that w is also 39 degrees. Thus we take (39+90)-180 = 51 degrees. (We know that one side is 90 degrees because it has a right angle)

Answer:

a) 80
b) 56

Step-by-step explanation:

a) Calculate the volume of the the cup using volume of cylinder equation: [tex]V = \pi r^{2} h[/tex]

Where V = Volume, r=radius, and h=height. Your answer should be in cubic inches ([tex]in^3[/tex]).
You're given diameter, so use equation [tex]d/2 = r[/tex] to find radius.
Substituting these equations will give you: [tex]V = \pi (d/2)^2 h[/tex]
However, the given volume of the sink is 3000[tex]\pi[/tex], meaning that you should modify your results to match this value. Do not substitute [tex]\pi[/tex] for 3.14..., leave it as a symbolic value. Your final V of the cup should = 37.5 [tex]\pi[/tex]
Divide the volume of the sink by the volume of the cup. This number will be the amount of cups needed to empty it. In equation form:
[tex]Vsink / V cup =[/tex] # of cups.
Note the the [tex]\pi[/tex] will cancel each other out, so there's not need to factor that in.
b) Repeat the steps above with the new d (diameter) value.
