Answer:

60 cm2

Step-by-step explanation:

Formula for finding out the area of the figure -

Area of full rectangle - Area of unshaded rectangle = Area of shaded region

Area of full rectangle =

Length (l) = 9+3 = 12 cmBreadth (b) = 4+4 = 8cm Area of full rectangle = l*b = 12*8 = 96cm2

Area of unshaded rectangle =

Length (l) = 9 cmBreadth (b) = 4 cmArea of unshaded rectangle = l*b = 4*9 = 36cm2

Putting the formula = 96-36 = 60cm2

Hence the area of shaded region = 60cm2

Answers

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.

What is an equation of a circle?

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.

A timer is started and a few moments later a swimmer dives into the water and then comes back up. The swimmer's depth (in feet) as a function of time (in seconds after the timer was started) is given by the equation h(t)=t2−12t+27

Rewrite the formula in factored form and select each true statement below.

The swimmer is underwater for 12 seconds.
The swimmer dives into the water 3 seconds after the timer was started.
The swimmer comes back up 9 seconds after the timer was started.
The swimmer dives to a maximum depth of 27 feet.
The swimmer dives into the water 12 seconds after the timer was started.

Answers

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.

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 number of trials is double the number of marbles in the jar. The number of trials would be double for each color in the jar. Both blanks are double.

Answers

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.

When can we find the volume of a considered figure?

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

The volume of the given figure

= Area x side

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).

Which values of x and y would make the following expression represent a real number?

Answers

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).

How to find the simplify the expression?

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).

What is the equation of a line parallel to y=(3)/(4)x-5 and passes through (12,-2)?

Answers

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.
