what is foci of ellipse calculator?

Answer: the answer is C

Step-by-step explanation:

To make the systems equivalent, we need to multiply both sides of each equation in the first system by the same constant in order to get the corresponding equations in the second system.

If we multiply the first equation in the first system by 4, we get:

16x + 20y = -12

If we multiply the second equation in the first system by -4, we get:

-20x + 12y = 52

Comparing this to the second system, we see that the equation -20x + 12y = 52 matches the second equation in the second system. Therefore, the value of C in the second system must be 52.

So, the answer is C.

The units of moment of inertia depend on the shape and dimensions of the object, and can be expressed in kg m², g cm², lb ft², or oz in².

The units of the moment of inertia depend on the shape and dimensions of the object. Some common units for a moment of inertia are:

kg m² (kilogram-meter squared)

g cm² (gram-centimeter squared)

lb ft² (pound-foot squared)

oz in² (ounce-inch squared)

These units represent the distribution of mass around an axis of rotation and are used in calculations involving rotational motion and torque.

The moment of inertia is a physical property of an object that determines its resistance to rotational motion. It depends on the mass distribution of the object and its orientation with respect to the axis of rotation. The moment of inertia is typically represented by the symbol I and is measured in units of kg m², g cm², lb ft², or oz in². The moment of inertia can be calculated using the object's mass, dimensions, and shape, and is used in calculations involving rotational motion, such as torque and angular acceleration. Different shapes and distributions of mass have different moments of inertia, which can affect the object's motion and stability.

Step-by-step explanation:

[tex] \sin(2 \alpha ) = 2 \sin( \alpha ) \cos( \alpha ) [/tex]

To find sin(a),

[tex] \sin( \alpha ) = \sqrt{1 - \cos {}^{2} ( \alpha ) } [/tex]

[tex] \sin( \alpha ) = \sqrt{1 - (0.6) {}^{2} } [/tex]

[tex] \sin( \alpha ) = \sqrt{0.64} [/tex]

Since sin is negative in the interval (270,360)

[tex] \sin( \alpha ) = - 0.8[/tex]

Now we can find sin(2a)

[tex]2( - 0.8)(0.6) = - 0.96[/tex]

2. The identity for cos(2x) is

[tex]2 \cos {}^{2} (x) - 1[/tex]

We know cos x is 0.6 so we get

[tex]2(0.6) {}^{2} - 1 = - 0.28[/tex]

part 3:

[tex] \tan(4x) = \frac{2 \tan(2x) }{1 - \tan {}^{2} (2x) } [/tex]

[tex] \tan(2x) = \frac{ \sin( 2x) ) }{ \cos(2x) } = \frac{ - 0.96}{ - 0.28} = 24[/tex]

For a pet shop to approximate 18 rabbits, it would take 6 weeks.

In the question, we have a formula that represents the number of rabbits available with them.

The amount of rabbits is dependent on another variable, Time.

The variables depend on each other, and the number of rabbits with the pet shop relies on the number of weeks.

R(t)= 2t(2/3) + 10

If the number of rabbits is 18, then the value of the equation would be equal to 18.    [R(t) = 18]

18= 2t(2/3) +10

18= 4t/3 + 10

8 X 3 = 4t

24/4 = t

6 = t

Therefore, 18 rabbits are approximated by the pet store in 6 weeks.

There are 9 employees at the smaller location and 12 employees at the larger location.

Let's use the following variables:

Let x be the number of employees at the smaller location.

Let y be the number of employees at the larger location.

We know that the total number of employees is 21, so we can write:

x + y = 21

We also know that "four times the number of employees at the larger location is six less than six times the number of employees at the smaller location". In other words, we can write:

4y = 6x - 6

Simplifying this equation, we get:

2y = 3x - 3

We now have a system of two equations with two variables:

x + y = 21

2y = 3x - 3

We can solve this system using substitution or elimination. Here, we'll use substitution method:

From the second equation, we can solve for x in terms of y:

2y = 3x - 3

3x = 2y + 3

x = (2/3)y + 1

We can now substitute this expression for x into the first equation:

x + y = 21

(2/3)y + 1 + y = 21

(5/3)y = 20

y = (3/5) × 20

y = 12

Substitute y = 12 back into x + y = 21, we get:

Answer:

(a) To find out how long it takes for Claudia to catch up with Cindy, we can first calculate the head start that Cindy had before Claudia started. Cindy had a head start of:

d = rt = 108 km/h x 1 h 40 min = 180 km

where d is the distance that Cindy traveled during the 1 hour 40 minutes (1.67 hours) between her departure and Claudia's departure, r is Cindy's speed, and t is the time she traveled.

When Claudia started, both Cindy and Claudia were 180 km away from Beach Town. The distance between them decreases at a rate equal to the difference in their speeds, which is:

124 km/h - 108 km/h = 16 km/h

So Claudia catches up at a rate of 16 km/h. The time it takes for Claudia to catch up is then:

t = d / r = 180 km / 16 km/h = 11.25 hours

However, we need to subtract the 1 hour 40 minutes (1.67 hours) that Cindy traveled before Claudia started to find the actual time Claudia took to catch up with Cindy:

t = 11.25 hours - 1.67 hours = 9.58 hours

Therefore, Claudia took about 9 hours and 35 minutes (0.58 x 60 minutes) to catch up with Cindy.

(b) When Claudia catches up with Cindy, they are both the same distance away from Beach Town. Cindy has already traveled 180 km when Claudia catches up, so the distance they are from Beach Town is:

600 km - 180 km = 420 km

Therefore, they were 420 km away from Beach Town when Claudia caught up with Cindy.

Option C. The transformation that does not preserve congruence is a dilation by a scale factor of 5.

Congruence is the property of having the same size and shape. In geometry, transformations are operations that change the position, size, or orientation of a figure. Some transformations, such as reflections, translations, and rotations, preserve congruence, meaning that the resulting figure is congruent to the original figure. Other transformations, such as dilations, do not preserve congruence, meaning that the resulting figure is not congruent to the original figure.

A dilation is a transformation that changes the size of a figure by stretching or compressing it. A dilation by a scale factor of 5 means that every point of the figure is multiplied by 5 with respect to a fixed point called the center of dilation. The resulting figure is similar to the original figure, but not necessarily congruent.

On the other hand, reflections, translations, and rotations preserve congruence. A reflection across the x-axis reflects the figure across the x-axis while preserving its shape and size. A translation 4 units up moves the figure up without changing its shape or size. A rotation 90° counter-clockwise rotates the figure 90 degrees counter-clockwise while preserving its shape and size.

Pania ate a quarter of the pizza, leaving 3/4 (since 1/4 + 3/4 = 1) for Pita and Paula.

Pita then ate one sixth of what remained, which is one sixth of 3/4 or 3/24, leaving 21/24 (or simplifying to 7/8) for Paula.

Paula then ate two fifths of what remained after Pita had eaten, which is two fifths of 7/8 or 14/40, leaving 26/40 (or simplifying to 13/20) for Penny.

Answer:

x = 108

Step-by-step explanation:

To solve the equation x/6 - 6 = x/18 + 6, we first need to get rid of the fractions by multiplying both sides by the least common multiple of the denominators, which in this case is 18.

So, we have:

18(x/6 - 6) = 18(x/18 + 6)

Simplifying this, we get:

3x - 108 = x + 108

Next, we want to isolate the variable x on one side of the equation, so we'll subtract x from both sides:

2x - 108 = 108

Finally, we'll add 108 to both sides to get:

2x = 216

Dividing both sides by 2, we get:

x = 108

Therefore, the value of x that makes the equation true is 108.

the total area available for the design on the soapbox car should be 636 inches² (square inches).

The correct calculations for the area of each side are:

Area of the first side = 6 inches x 54 inches

= 324 square inches

Area of the second side = 54 inches x 14 inches

= 756 square inches

Area of the third side = 14 inches x 24 inches

= 336 square inches

Area of the fourth side = 24 inches x 6 inches

= 144 square inches

To get the total area available for the design, we need to subtract the area of the top and bottom of the soapbox car, which are not included in the original measurements. If we assume the top and bottom are each rectangular and have the same dimensions as the first and third sides, we can calculate their total area as:

Area of the top = 6 inches x 54 inches

= 324 square inches

Area of the bottom = 6 inches x 54 inches

= 324 square inches

Total area of the top and bottom = 324 + 324

= 648 square inches

Finally, we can subtract the area of the top and bottom from the total area of the four sides to get the area available for the design:

Total area available for the design = (324 + 756 + 336 + 144) - 648

= 636 square inches.

How to find?

To find out how many cups of chocolate chips Rana has left, we need to subtract the amount she used in the cookie recipe from the amount she bought.

First, we need to convert both mixed numbers to improper fractions, so we can subtract them.

Three and three-fourths cups can be written as:

3\frac{3}{4} = \frac{(3 \times 4) + 3}{4} = \frac{12 + 3}{4} = \frac{15}{4}

Two and one-third cups can be written as:

2\frac{1}{3} = \frac{(2 \times 3) + 1}{3} = \frac{7}{3}

We can use the ratio of distance to time for the cheetah's first run to find how long it will take to run 147 meters.

The speed of the cheetah is given by:

Speed = distance/time

In the first run, the cheetah ran 196 meters in 8 seconds, so its speed was:

Speed = 196/8 = 24.5 meters per second

To find out how long it will take for the cheetah to run 147 meters, we can use the speed we just calculated and the distance we want to find:

Speed = distance/time

24.5 = 147/time

Solving for time:

time = 147/24.5

time = 6 seconds

Therefore, it will take the cheetah 6 seconds to run 147 meters.
