Answer:

a. A = 647

   P = 120

b. A = 192

   P = 70

Step-by-step explanation:

a. A = (16 x 12) + (13 x 35) = 192 + 455 = 647

   P = 16 + 12 + 19 + 13 + 35 + 25 = 120

b. A = (12 x 8) + (8 x 12) = 96 + 96 = 192

   P = 12 + 8 + 7 + 8 + 12 + 8 + 7 + 8 = 70

Answer:

Step-by-step explanation:

in the first question the format is simply (x, y) and because it is a translation, we are basically just moving the point by these numbers, with this information, it is simply moving x to the left(negative) 8 times, and y(up/positive) 4 times. The next question is simply moving the point across the x axis by the same amount that it is above the x axis, so it would be one down from the x-axis' bold line, or in this case moved 2 y-units down.

The required function is P(t)=50000 + 5000t.

In this problem we need to form the function of the population in a town.

Here it is given that the initial population of the town is 50000.

the rate at which the population increases is 5000 per year.

So, the increase for the first year will be 5000. And the population will be 55000.

Then again for the next year the growth will be 5000 and the population will be 50000 + (5000×2)

        = 60000

So we can see clearly that the population is varying with time and we can write the function as P(t)=50000 + 5000t where t is the time in years.

The value of x that makes the lines m and n to be parallel lines is 45 degrees

The figure that completes the question is added as an attachment

From the figure, we have the following angles

Angle = x and 3x

The angles are interior of parallel lines

This means that they add up to 180 degrees

So, we have the following equation

Angle 1 + Angle 2 = 180 degrees

Substitute the known values in the above equation

So, we have

x + 3x = 180

Evaluate the like terms in the above equation

So, we have:

4x = 180

Divide both sides of the above equation by 4

So, we have

x = 45

Hence, the value of x that makes the lines m and n to be parallel lines is 45 degrees

x(x – 5) = 176 is the correct equation to find the greater integer.

As the question mentions, the greater integer is x. So, the smaller integer will be (x - 5). Also, we are informed that their product is 176.

Now, representing the given information as mathematical expression -

x(x – 5) = 176

On further multiplication on Left Hand Side, we get the equation -

x² - 5x = 176

Rewriting the equation -

x² - 5x - 176 = 0

Further solving the equation to validate it.

x² - 16x + 11x - 176 = 0

x (x - 16) + 11 (x - 16) = 0

(x - 16) (x + 11) = 0

x = 16, -11

As stated, the integers are positive. So, the value of x and hence greater integer is 16.

Value of small integer = 16 - 5

Value of small integer = 11

So, the two integers are 16 and 11. Their product is 176 hence, our formed equation is correct.

Therefore, the equation that can be used to find x is : x(x – 5) = 176.

The slope of the line as shown in the diagram attached below = rise/run = 3/5.

The rise of a line over the run of a line would give us the slope of a line on a coordinate plane.

With the given line in the diagram, the image attached below shows the rise as represented by a red line while the run is represented by the blue line.

Therefore, we have:

Run = 10 units

Rise = 6 units

Slope (m) of the line = rise/run = 6/10

'Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

Given dimensions:

Twin sized air mattress (39 by 8.75 by 75 inches).

Queen sized mattress (60 by 8.75 by 80 inches)

Now, Volume of twin sized mattress

=39* 8.75* 75

= 25593.35 cubic inch

Volume of queen sized mattress,

=60* 8.75* 80

= 42000 cubic inch

as, To fill 25593.35 cubic inch it takes 5  minutes

so, to fill 1 cubic inch = 5/25593.35

The value of csc x=-13/5.

Given that the sin x=-5/13 and x∈[3π/2 , 2π).

A trigonometric function is a real function that relates the angle of a right triangle to the ratio of the lengths of the two sides. The basic functions are sin, cos, tan, cot, sec, csc.

The given function is sin x=-5/13.

As we all know that sin x=1/csc x or csc x=1/sin x.

As it is given that x∈[3π/2 , 2π) that means x lies in fourth quadrant and in fourth quadrant sin and csc is negative in it.

So, we will apply this identity csc x=1/sin x, we get

csc x=1/(-5/13)

csc x=-13/5

And it also lies in x∈[3π/2 , 2π).

Hence, the value of csc x when sin x=-5/13 and x∈[3π/2 , 2π) is csc x=-13/5.

The probability of an occurrence is a number between 0 and 1, with 1 representing certainty and 0 representing impossibility.

Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half (which could also be written as 0.5)
