Calculate the length of the sides marked x and y

Answers

Step-by-step explanation:

there is no side marked y.

to get x :

the graphic shows us already the split of the overall object into sub-shapes :

2 right-angled triangles

1 rectangle

x is the sum of the width of the rectangle and the shorter leg of the larger, top right-angled triangle.

to get both we need to use Pythagoras :

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle), a and b being the legs of the triangle.

let's start with the shorter leg of the larger triangle.

the Hypotenuse is 18, and the longer leg is the same as the length of the "underlying" rectangle : 10.

so, we get

18² = 10² + leg1²

324 = 100 + leg1²

leg1² = 224

leg1 = sqrt(224) = 14.96662955...

now to the width of the rectangle.

it is the same as the longer leg of the smaller triangle on the right side.

its Hypotenuse is 5. its shorter leg is 2.

so, we get

5² = 2² + leg2²

25 = 4 + leg2²

leg2² = 21

leg2 = width rectangle = sqrt(21) = 4.582575695...

x = leg1 + leg2 = 14.96662955... + 4.582575695... =

= 19.54920524...

The width of a human hair is 2 x 10-5 meters. The width of a piece of sand is 1.5 x 10¹ meters.
What is the difference in the widths, in meters, of the human hair and the piece of sand?

Answers

The difference in the widths, in meters, of the human hair and the piece of sand is [tex]1.4998*10^{-1}[/tex] m.

It is given in the question that:-

Width of a human hair = [tex]2*10^{-5}[/tex] m

Width of a piece of sand = [tex]1.5*10^{-1}[/tex]m

We have to find the difference in the widths, in meters, of the human hair and the piece of sand.

We know that,

Difference between the widths = Width of a piece of sand - Width of a human hair

Hence, we can write,

Difference between the widths = [tex]2*10^{-5}[/tex] m - [tex]1.5*10^{-1}[/tex]m

We can write,

[tex]1.5*10^{-1}=15000*10^{-5}[/tex]

Hence,

Difference between the widths =

[tex]15000*10^{-5} - 2*10^{-5}= 14998*10^{-5} = 1.4998*10^{-1}[/tex] m

An event tent rental business charges a fee to set up and take down a tent, plus an hourly rate. The equation y = 65x + 150 can be used to find the total fee, y, for renting a tent for x hours.

Part A: What’s the hourly Rate?

Part B: What is the fee to set up and take down the tent?

Answers

The hourly rate is $65 per hour. While the fees to set up the tent is $100 and to take down after t hours is 65t + 100.

As we can see, the relation between the total fees and the hours for renting in hours is related by the equation,

y = 65x + 100

We are assuming that the price is in dollar.

This is an equation of line in slope-intercept form.

In slope intercept form, the coefficient of x is the slope of the line, which is 65 here.

So, the rate at which the fees is changing with time is 65.

So, the hourly rate will be $65 per hours.

The fees when tent is set can be calculated by,

We should put x = 0, because it is the start,

So,

y = 100

So, the fee to set up is $100.

Let us say the tent is removed after t hours, so the fees will be,

y = 65t + 100.

Fees of taking down the tent is $(65t+100)

The equation of the function in the standard form is:

3x + y = 25.

Given, From the table we can get the dy/dx which is the slope (m) ,

Therefore,

dy/dx = (7 - 10 ) / ( 4 - 3 )

dy/dx = -3

f(x) = ax² + bx + c, where a, b, and c are all numbers and an is not equal to 0, is the definition of a quadratic function. A parabola is the shape of a quadratic function's graph. Despite the fact that a parabola's "width" or "steepness" and opening direction can change.

Now,

( y - y₁ ) = m ( x - x₁ )

Putting the value from the table,

( y - 10 ) = -3 ( x -5 )

⇒ y - 10 = -3x + 15

⇒ 3x + y = 25

Hence the equation of the line in standard form is 3x + y = 25.

-9x+1=-80 what does the x equal

Answers

Answer:

Simplifying

x = 9

Step-by-step explanation:

Simplifying

9x + -1 = 80

Reorder the terms:

-1 + 9x = 80

Solving

-1 + 9x = 80

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1' to each side of the equation.

-1 + 1 + 9x = 80 + 1

Combine like terms: -1 + 1 = 0

0 + 9x = 80 + 1

9x = 80 + 1

Combine like terms: 80 + 1 = 81

9x = 81

Divide each side by '9'.

What are the coordinates of the point on the direct line segment from (-5, -10) to (2, 4) that partitions the segment into a ratio of 2 to 5?

Answers

Now the given coordinates are,

(-4,10) and (2,-10)

Thus, we have,

x₁ = -4

y₁ = 10

x₂ = 2

y₂ = -10

Given ratio, m₁ : m₂ = 1 : 3

⇒ m₁ = 1; m₂ = 3

Let (x,y) be the coordinates of the point on the directed line segment from (-4,10) to (2,-10) that partitions the segment into a ratio of 1 to 3.

Since the section formula is given as,

So, x = (m₁x₁ + m₂x₂) / (m₁ + m₂)

y = (m₁y₁ + m₂y₂) / (m₁ + m₂)

Put the values,

x = [1(-4) + 3*2)] / (1 + 3) = (-4+6) / 4 = 2/4

⇒ x = 1/2

Similarly y = [1(10) + 3*(-10)] / (1 + 3) = (10-30) / 4 = -20/4

⇒ y = -5

So, the required coordinates are (1/2, -5)

Thus, the coordinates of the point on the directed line segment that partitions the segment into a ratio of 1 to 3 is (1/2, -5).

a farmer decides to enclose a rectangular​ garden, using the side of a barn as one side of the rectangle. what is the maximum area that the farmer can enclose with 48 ft of​ fence? what should the dimensions of the garden be to give this​ area? question content area bottom part 1 the maximum area that the farmer can enclose with 48 ft of fence is

Answers

The maximum area that the farmer can enclose for the rectangular garden is 488 sq ft and the dimensions of the rectangular garden are 24ft and 12 ft respectively.

It is given that a farmer decided to enclose a rectangular garden with one side using the barn of a tree and other 3 sides with 48 ft of fencing.

Let the length of the rectangle be y and the breadth of the rectangle be u.

So perimeter of the fencing needed = y + 2u (as one side is barn)

∴ y + 2u = 48

⇒ y = 48 - 2u (equation 1)

Area = yu (equation 2)

Putting the value of variable y from equation 1 in equation 2 we have,

Area = (48-2u)u

∴ Area = 48u - 2[tex]u^{2}[/tex]

⇒ Area = -2[tex]u^{2}[/tex] + 48u

⇒ Area = -2([tex]u^{2}[/tex] - 24u)

⇒ Area = -2([tex]u^{2}[/tex] - 24u + 144) + 288 (using completing the square method)

⇒ Area = -2[tex](u-12)^{2}[/tex] + 288

So the maximum area is 288 sq units as for any value of u the area value will decrease as seen from the above equation.

So if Area = 288

Then yu = 288

⇒ u = 288/y equation 3

Putting this value in Perimeter equation 1 we have,

y = 48 - 2u

⇒ y = 48 - 2 x [tex]\frac{288}{y}[/tex]

⇒ [tex]y^{2} = 48y - 576[/tex]

⇒ [tex]y^{2} - 48y + 576 = 0[/tex]

⇒ [tex](y-24)^{2}[/tex] = 0

Solving we get y = 24 ft

Hence the value of u is calculated as follows:

⇒ u = 288 / y

⇒ u = 288/ 24 = 12 ft

The maximum area that the farmer can enclose is 488 sq ft and the dimensions of the rectangle are 24ft and 12 ft respectively.

Answers

The air is filled inside the balloon at the rate of 1600π cm³/sec.

What is termed as the rate of change?The momentum of a variable is represented by the rate of change, which is used to arithmetically define the percentage change in value over a specified period of time.The amount of air blown through will be evaluated in volume per unit of time. That is the rate at which volume changes with respect to time.

The rate during which air is blown into the balloon is identical to the rate that the volume of a balloon grows.

Volume of the spherical balloon;

V = (4/3)πr³

Given is dr/dt = 4 cm/sec.

To calculate the volume change with respect to time.

dV/dt when r = 10 cm.

The equations of the line will be expressed as y = 4 and y = -2x + 11 respectively.

Slope of a line may be defined as the steepness of a curve on graph. Slope is denoted by 'm'. If we are given two points (x₁, y₁) and (x₂, y₂) then the slope of line can be given by m = (y₂ - y₁)/(x₂ - x₁). Now, we have a line y = 6 and this line is parallel to x-axis, so the slope of this line is zero. Since, we have to find the equation of line parallel to given line so the slope of the line parallel to line y = 6 will also be equal to zero. Now, equation of line from points (3, 4) and slope zero is given by

(y - 4) = 0×(x - 3)

=> y - 4 = 0

=> y = 4 which is the required equation.

Now, for the second part we have need to find the equation of line parallel to line y = -2x - 1 and from point (4, 3). The slope of new line is -2 which will be same as the given line as they both are parallel. Now, equation of line will be

(y - 3) = -2(x - 4)

(y - 3) = -2x + 8

y = -2x + 8 + 3

=> y = -2x + 11 which is the required equation.

If the probability that an event will occur is changed as a result of the occurrence of a previous event, the events are said to be dependent events.

There, are two types of events- dependent and independent. Independent ones are those wherein the occurrence of one event has no effect on the probability of occurrence of another one. For example- you and your classmate passing a test are both independent events.

On the other hand, dependent events are those events that are affected by a change in any one of the events probability changing. For example- studying for a test and passing the test are both dependent events.
