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 2: 8 + 2 + 3

Step 3: 10 + 3 [ corrected]

Step 4: 13

Answer:

First option, incorrect....

Step-by-step explanation:

This is because the interval is either below or above 26.8 by 0.6

-+ means

26.8 + 0.6 = 27.4

26.8 - 0.6 = 26.2

The confidence interval % can change

- The second option states 28 but that is not in the interval

- The third option is somewhat right but the parameter should be emphasized how confident you are

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:

(x+10)(x-10)

Step-by-step explanation:

The factor for x+10 is x+10 itself.

(x+10) = x+10

(x+10) occurs 1 time.

The factor for x-10 is x-10 itself.

(x-10) = x-10

(x+10) occurs 1 time.

The LCM of x+10, x-10 is the result of multiplying all factors the greatest number of times they occur in either term.

(x+10)(x-10)

The perimeter of the triangle ABC is [tex]10+\sqrt{10}[/tex] [tex]units[/tex].

The given parameters:

The length of AC = 3-(-2) = 5 unit

The length of AC = length of BC = 5 unit

The length of BC is calculated by applying Pythagoras theorem as follows;

[tex]BC^2=(4-1)^2+(3-2)^2[/tex]

[tex]BC^2=3^2+1^2[/tex]

[tex]BC^2=10[/tex]

[tex]BC=\sqrt{10}[/tex]

The perimeter of the triangle ABC is calculated as follows;

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)

Hope that helps! :)

Answer:

50 degrees

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

Step-by-step explanation:

The value of a³-B³ from the given quadratic equation is 12.05.

The roots to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

Given that, a and B are the roots of the equation 3x²+6x-2=0

By comparing 3x²+6x-2=0 with ax²+bx+c=0, we get a=3, b=6 and c=-2

The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.

Now, substitute a=3, b=6 and c=-2 in quadratic formula

That is, x = [-6 ±√(6² - 4×3×(-2))]/2×3

= [-6 ±√60]/6

= (-6±2√15)/6

= (-3±√15)/3

So, a=(-3+√15)/3 and B=(-3-√15)/3

Now, a³-B³ = [(-3+√15)/3]³- [(-3-√15)/3]³

= 12.05

Therefore, the value of a³-B³ from the given quadratic equation is 12.05.

Answer:

when you are comparing two sets of data, and one set is strongly skewed and the other is symmetric, which measures of the center and variation should you choose for the comparison?

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.

Answer:

94 square inches.

Step-by-step explanation:

Surface area is the area around a surface. Thus, in order to calculate the surface area of a rectangular prism, we just need to add up the different faces of it.

There are 2 5x4 faces, 2 3x5 faces, and 2 4x3 faces.

Thus, we get 2*20 + 2*15 + 2*12 = 40 + 30 + 24 = 94 square inches.
