Answer:

The equation of the elipse is

[tex]\frac{x^2}{169} + \frac{y^2}{25} = 1[/tex]

Step-by-step explanation:

Equation of an elipse:

The equation of a elipse with centre [tex](x_c,y_c)[/tex] has the following format:

[tex]\frac{(x - x_c)^2}{a^2} + \frac{(y - y_c)^2}{b^2} = 1[/tex]

Centre at (0,0):

Means that [tex](x_c,y_c) = (0,0)[/tex].

So

[tex]\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1[/tex]

Vertex at (13,0):

Vertex at 13 means that [tex]a = 13, a^2 = 13^2 = 169[/tex]

Focus at (-12,0):

Means that [tex]c = 12, c^2 = 12^2 = 144[/tex]

We have that:

[tex]a^2 = b^2 + c^2[/tex]

So

[tex]169 = b^2 + 144[/tex]

[tex]b^2 = 25[/tex]

So, the equation of the elipse is

[tex]\frac{x^2}{169} + \frac{y^2}{25} = 1[/tex]

Answer:

1/2 = 2/4   so:

1/2+1/4 = 2/4+1/4= 3/4

Answer:

m + n = 26 and n = 2m + 5

m = 7, n = 19

Step-by-step explanation:

Because we know that the sum of m and n is 26, we get the first equation. For the second equation, we are told that n is five more than twice m. So we multiple m by 2 and then add 5 to that to get what n is. This is our second equation.

We plug the second equation in for n in the first equation to get

m + (2m + 5) = 26

3m + 5 = 26

3m = 21

m = 7

And then for n, we solve the first equation to get

7 + n = 26

n = 19

Answer:

109.3

Step-by-step explanation:

The area of the figure in square centimeters is 89.6 cm².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

Given:

We have the figure consist of rectangle and 2 quadrants.

Then to calculate area of figure

= Area of 2 quadrant  +  area of rectangle

So,  Area of 2 quadrant = 2 x πr²/4 = πr²/2

                                        = 3.14 x 5² /2

                                        = 19.625 cm²

and, area of rectangle= l x w= 7 x 10 = 70 cm²

Thus, area of figure

= Area of 2 quadrant  +  area of rectangle

= 19.625 + 70

= 89.625 cm²

Answer:

Each value (1 to 6) has exactly the same probability of being rolled.

Step-by-step explanation:

Given

Rolls: 10

Outcome: 5 5 1 3 2 1 5 6 5 1

Required

Which is true about the next 10 rolls

In the roll of a fair die (as stated in the question), each face has equal probability of being the outcome of individual rolls.

This implies that options (a), (b) and (c) are not true because they do not support the above statement,

Hence, (d) is correct

Answer:

132

Step-by-step explanation:

a straight line is 180% , so if the other triangle has a 48% we would subtract 180% by 48%.

Answer:

132

Step-by-step explanation:

Since those two angles are linear, they would form to make 180 degrees. So 180-48 is 132.

Step-by-step explanation:

This is very hard to be explained, sorry.

Answer:

The first one:   35/10

Second:   6/10

Step-by-step explanation:

These are the answers because since you are trying to solve to get a denominator of 10, you must multiply both the to and bottom numbers by whatever you need to get the denominator to 10.  For example, for 3/5 you would multiply both the top and bottom numbers by 2, because you nned to multiply the denominator by 2 to get 10.

Answer:

$911.02

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1.25%/100 = 0.0125 per year,

then, solving our equation

I = 845 × 0.0125 × 6.25 = 66.015625

I = $ 66.02

The simple interest accumulated

on a principal of $ 845.00

at a rate of 1.25% per year

for 6.25 years is $ 66.02.

Answer:

2/6 socks are white.

Step-by-step explanation:

The denominator (6) is the amount of socks you have.

If 2/6 are blue and 2/6 are green. 4/6 are Blue & Green.

To find the remaining amount of socks you would simply subtract 6/6 by 4/6

That would leave you with 2/6 of the socks being WHITE.
