Answer:

y = 28 - x

Step-by-step explanation:

The variable x represents how many buttons Paula had before giving 28 away and the variable y represents how many buttons she has now.

The complete question is

"Which values of x and y would make the following expression represent a real number? (4 + 5i)(x + yi)"

The value of x and y are all points that satisfy the equation would be,(4,-5).

Use the distributive property to simplify the expression.

The given expression is,

(4 + 5i)(x + yi)

4(x + yi)+ 5i (x + yi)

4x + 4yi + 5xi + 5yi^2

We know that i^2 = -1

4x + 4yi + 5xi - 5y

(4x - 5y) +i (  4y + 5x)

In x+iy, x is the real part and y is the imaginary part.

If the given expression represents a real number it means the imaginary part must be zero.

4y + 5x= 0

All the points which satisfy the above equation are the values of x and y for which the given expression is a real number.

For eg. (4,-5)

4y + 5x

4(-5) + 5(4)

= 0

LHS=RHS, which means the point satisfies the equation and the value of x and y are (4,-5).

The theoretical probabilities are

Red: 8/20 = 0.4

Blue:6/20 = 0.3

yellow:6/20 = 0.3

The experimental Probabilities are

Red: 11/40 = 0.275

blue: 11/40 = 0.275

Yellow: 18/40=0.45

Both probabilities add to 1 as they should

The yellow is the highest disproportionate answer and it really shouldn't be. If anything it should be red. (0.45 > 0.4 comparing yellow experimental with red theoretical. The yellow is way more than it should be)

The area of the given figure is 16.4 cm² and the Length of the side is 8.1 cm. therefore, the volume of the given figure is 132.84 cm³.

For finding the volume of the considered figure, we somehow need measurement of its correct dimensions by which we would be able to recreate the figure.

By any means, if we could get enough measurement, then we'd be able to characterize the figure, and thus, get its volume.

Area = 16.4 cm²

Length of side = 8.1 cm

Answer:

3.) (5,2), (5,5), and (9,2)

Step-by-step explanation:

The triangle currently has the coordinates (2,0), (6,0), and (2,3).

If you want to translate the triangle up 2 units, you need to add 2 to each "y" value.

(2,0)  -----------> y = 0  ------------> new y = 2

(6,0) -------> y = 0   --------------> new y = 2

(2,3)  ----------> y = 3 -----------> new y = 5

If you want to translate the triangle 3 units to the right, you need to add 3 to each "x" value.

(2,0)  -----------> x = 2  ------------> new x = 5

(6,0) -------> x = 6  -------------->  new x = 9

(2,3)  ----------> x = 2 ----------> new x = 5

Therefore, the new coordinates are (5,2), (9,2), and (5,5).

The formula in factored form is (t - 3)(t - 9) and the swimmer dives into the water 3 seconds after the timer was started also, the swimmer comes back up 9 seconds after the timer was started.

Analysis:

at h(t) = 0 that is when the diver has not dived or at height 0 foot

the equation becomes [tex]t^{2}[/tex] -12t + 27 = 0

by factorizing,

[tex]t^{2}[/tex] -9t -3t + 27 = 0

(t-9)(t-3) = 0, this is the equation in factored form.

t = 3 or 9

These are the times, the height h(t) = 0

Which means the swimmer dived 3 seconds later or got to the top of water after 9 seconds in which case h(t) = 0

In conclusion, the swimmer dives 3 seconds later after the timer was started and the swimmer comes back up after 9 seconds are the true statements for this problem.

Answer:

What is this supposed to mean even?

Step-by-step explanation:

A parallel line has the same slope as the original line. So in this case the slope of the line is also 3/4. Now how do we know if it intersects the point? We need to adjust the y intercept.



Currently, we know the equation of the line is y= 3/4 x + b, where b is the thing we are looking for. We also have a point, which supplies the x and y. Plug that in and solve for b

-2 = (3/4)*(12) + b

You'll get b= -11

So the equation of the parallel line intersecting the point given is y= 3/4x -11.

I am assuming that the slope is 3/4 based on the way you formatted the original equation, but it's the same steps if the slope is different.

The center of the circle will be (4, -3) and the radius of the circle will be 6 units. Then the correct option is A.

A circle can be characterized by its center's location and its radius's length.

Let the center of the considered circle be at the (h,k) coordinate.

Let the radius of the circle be 'r' units.

Then, the equation of that circle would be:

(x - h)² + (y - k)² = r²

The equation is given below.

x² - 8x + y² + 6y - 11 = 0

     x² - 8x + y² + 6y = 11​​

Then the center and the radius of the circle will be

x² - 8x + 16 + y² + 6y + 9 = 11​ + 16 + 9

             (x - 4)² + (x + 3)² = 36

             (x - 4)² + (x + 3)² = 6²

Thus, the center and the radius of the circle will be (4, -3) and 6 units respectively.
