Answer:

Step-by-step explanation:

To write the equation of a line in slope-intercept form (y = mx + b), we need to find the slope of the line (m) and the y-intercept (the point where the line crosses the y-axis, which is represented by b).

We can use the point-slope formula to find the equation of the line that passes through the points (-2,-2) and (5,12):

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line, and m is the slope of the line.

Plugging in the values for the given points and solving for m, we get:

m = (12 - (-2)) / (5 - (-2))

= 14 / 7

= 2

Now that we have the slope, we can use either of the given points to find the y-intercept (b). Let's use the point (-2,-2):

y = mx + b

-2 = 2(-2) + b

-2 = -4 + b

b = -2 + 4

b = 2

Therefore, the equation of the line in slope-intercept form is:

y = 2x + 2

This is the equation of the line that passes through the points (-2,-2) and (5,12).

The measure of angle B is 141 degrees

Given,

In the question:

There is a seven sided polygon ABCDEFG

The measure of angle BCD is 148 degrees,

The measure of angle DEF is 142 degrees,

The measure of angle EFG is 130 degrees,

The measure of angle FGA is 129 degrees,

and the measure of angle GAB is 120 degrees.

Angle CDE is a right angle.

To find the m∠B.

Now, According to the question:

The sum of angles in a polygon adds up to 180(n - 2), where n is the number of sides of the polygon

The angles are given as:

∠BCD = 148

∠DEF = 142

∠EFG = 130

∠FGA = 129

∠GAB = 120

∠CDE = 90

So, the measure of angle B is calculated using:

∠B + 148 + 142 + 130 + 129 + 120 + 90 = 180(n - 2)

∠B + 759 = 180(n - 2)

The value of n is 7

∠B + 759 = 180(7 - 2)

∠B + 759 = 180 x 5

∠B = 900 - 759

∠B = 141

Hence, the measure of angle B is 141 degrees

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m =  [tex]tan \theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

The percentages of compact and subcompact cars the division should plan to manufacture to maximize the expected number of cars demanded each week are 24.5% and 24.5%.

The Latin word per centum, which means "hundred" or "by the hundred," is the source of the word "percent." The Italian term per cento, which means "for a hundred," gradually shrank to become the sign for "percent," which is now used globally. It eventually vanished entirely. The word "per" was frequently shortened to "p."

Given,

If the oil price increases at a higher than normal state,

Demand for the compact cars=1400

Demand for the sub-compact cars=2600

If the oil price increases at a normal rate,

Demand for the compact cars=3500

Demand for the sub-compact cars=2300

Assuming that the probability of price increases at higher than the normal rate is 50% and at a normal rate is 50%.

Then,

Demand for compact cars=50%(1400)+50%(3500)

=(50/100)×1400+(50/100)×3500

=700+1750

=2450

Demand for the sub-compact cars=50%(2600)+50%(2300)

=(50/100)×2600+(50/100)×2300

=1300+1150

The length and width of the rectangular pen that optimizes the area are 400 feet and 200 feet, respectively, according to the perimeter of a rectangle.

The perimeter of a shape is the sum of the lengths of all its edges. For example, a triangle has three edges, hence its perimeter is equal to the sum of those three lengths.The perimeter of a form can be calculated by adding the lengths of all its sides. A perimeter example is what? A field with a length of 24 yards and a width of 15 yards, for instance, will have a perimeter of 78 yards.

calculation

In order to construct a hog pen, I have 800 feet of fencing.

Assume that "l" represents the rectangle's length and "w" its width.

One of your properties borders a river that I own.

I can secure my property with fencing on its three sides.

because of this, the fencing's necessary perimeter p = l + 2w

The fencing's perimeter is now equal to

⇒ l + 2w = 800

= l = 800 - 2w

now the  rectangle's area  = A = lw

Therefore,  A = l * w = w ( 800 - 2w ) = 800w - [tex]2w^{2}[/tex]

By diffusing the area equation, we can figure out the rectangle's greatest area.

Therefore, A' = 800 - 4w

Again, A" = -4

The rectangle has the largest area since the second order differentiation is constant negative.

Put simply, we obtain: A' = 0 , A' = 800- 4w

⇒800- 4w = 0

⇒ 4 w = 800

⇒ w = 200

So the rectangle has a 200-foot width.

The rectangle's length is currently:

l = 800 - 2w = 800 - 2 ( 200 ) = l = 400 feet

The length and width of the rectangular pen that optimizes the area are 400 feet and 200 feet, respectively, according to the perimeter of a rectangle.

21 miles per hour is the speed of boat still in water and 9 miles per hour is the speed of current.

Downstream - A boat is said to be moving downstream if it is moving in the same direction as the stream.

Upstream - A boat is said to be moving upstream if it is moving downstream of the stream. The term "upstream speed" in this context refers to the boat's net speed.

13) Given that, a boat traveled 280 miles downstream and back.

Time taken by boat in downstream is 7 hours and in upstream is 14 hours.

Let the speed of a boat be x miles per hour and the speed of a current be y miles per hour.

So, the total speed in downstream is x+y miles per hour and the total speed in upstream is x-y miles per hour.

We know that, Distance = Speed × Time

Now, 280=(x+y)×7

⇒ x+y=40 ------(I)

Here, 280=(x-y)×14

⇒ x-y=20 ------(II)

Add equation (I) and (II), we get

x+y+x-y=40+20

⇒ 2x=60

⇒ x=30 miles per hour

So, x+y=40

⇒ y=10 miles per hour

14) Given that, a boat traveled 252 miles downstream and back.

Time taken by boat in downstream is 12 hours and in upstream is 84 hours.

Let the speed of a boat be p miles per hour and the speed of a current be q miles per hour.

So, the total speed in downstream is p+q miles per hour and the total speed in upstream is p-q miles per hour.

We know that, Distance = Speed × Time

Now, 252=(p+q)×12

⇒ x+y=21 ------(I)

Here, 252=(p-q)×84

⇒ p-q=3 ------(II)

Add equation (I) and (II), we get

p+q+p-q=21+3

⇒ 2p=24

⇒ p=12 miles per hour

So, p+q=21

⇒ q=9 miles per hour

Therefore, the speed of boat still in water is 21 miles per hour and the speed of current is 9 miles per hour.

If x² /y³ = 1 and x^4/2y³ = -1,  the value of the sum of x and y would be y^(3/2).

The fundamental procedures for altering and combining mathematical objects, such as integers and functions, are known as operations in mathematics. These operations, which are used to carry out mathematical computations on numbers, generally include sum, subtraction, multiplication, and division. Operations may also be applied to other types of mathematical objects, like as vectors, matrices, and sets, to execute more sophisticated operations such as vector addition, matrix multiplication, and set intersection. The outcome of an operation is referred to as an operand, and the procedures for combining operands are referred to as the operation's laws. A basic idea in mathematics, operations are applied in many different areas of science and math.

How to solve?

If x² /y³ = 1, then x² = y³

If x^4/2y³ = -1, then x^4 = -2y³

The sum of x and y is x + y = (x²)^1/2 + (y³)^1/3 = y^(3/2) + y

x + y = (x^4)^1/4 + (y³)^1/3 = (-2y³)^1/4 + y^(3/2) = -y + y^(3/2)

x + y = 0 + y^(3/2) = y^(3/2)
