Answer:

Option (2)

Step-by-step explanation:

Formula to get the surface area of a sphere is,

Surface area = 4πr²

Here 'r' = Radius of the sphere

We have to calculate the surface area of a sphere with radius r = 9 inches.

By substituting the value of r in the formula,

S = 4π(9)²

Therefore, Option (2) will be the correct option.

Answer:

D) The vectors point in opposite directions.

Step-by-step explanation:

got it right on edge :)

see graph below

Given vectors u = (-2,1) and v =( 4, -2) represents the vectors point in opposite directions.

"Vectors is a quantity which gives us both magnitude and direction of the given quantity."

According to the question,

Given vectors u(-2,1) and v(4,-2) represented on the graph.

From the graph we conclude that given vectors u and v

Does not form obtuse angle of approximately 93° , 96° or 127°.

The vector 'u(-2,1)' is in second quadrant and v(4,-2) is in fourth quadrant.

Second quadrant and fourth quadrant are in opposite direction.

Hence, we conclude the vectors point in opposite directions.

Answer:

B) -|x+3|

Step-by-step explanation:

Use the equation y=a|x-h|+k

a=-1 since the graph opens downwards with no stretch or shrink

h=-3 since the horizontal shift is 3 units right

k=0 since there's no vertical shift

Therefore, our equation is y=-|x+3| making B the correct answer

Answer:

x=19.5 or 19 1/2

Step-by-step explanation:

To find what x is we need to get x on one side of the equal sign with the numbers on the other side, but first, we need to add the same variables and numbers together.

Add:

4x+12=90

Move the 12 to the other side by subtracting 12 on both sides (You use the inverse of what you want to move to the other side)

4x+12-12=90-12

4x=78

Divide:

You need to divide 4x by 4 (Since 4x is the same thing as 4*x you need the inverse of multiplication to reverse it which is division)

x=19.5 or 19 1/2 (Since 1/2 is the same thing as 0.5)

Answer:

Step-by-step explanation:

The required slope of the line is 1 which passes through the points (-5, -3) and (-7, -5).

The slope of a line is defined as the change in the y-coordinate (the "rise") divided by the change in the x-coordinate (the "run").

To determine the slope of the line that passes through the points (-5, -3) and (-7, -5), we can use the formula:

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Let

x₁ = -5, y₁ = -3

x₂ = -7, y₂ = -5

∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )

Plugging in the coordinates of the two points, we get:

slope = (-5 - (-3)) / (-7 - (-5))

Simplifying this expression gives us:

slope = -2 / -2

Which simplifies to:

slope = 1

Therefore, the slope of the line that passes through the points (-5, -3) and (-7, -5) is 1.

Answer:

x= 1

y= -2

Step-by-step explanation:

1. y+3x=1 subtract 3x from both side to get y= 1-3x

2. Put the new found y value in the equation

3x-4(1-3x)=11

3. Distribute the 4

3x-4+12x=11

4. Add 4 to both sides

3x+12x=15

5. Add the x's

15x=15

6. Solve for x

x=1

7. Plug in the x in the y equation y= 1-3x

y=1-3(1)

8. Solve for y

y= -2

The solution to the system of equations is x = 1 and y = -2.

To solve the system of equations using substitution, we need to solve one of the equations for one variable in terms of the other variable and then substitute that expression into the other equation. Let's solve the second equation for y and then substitute it into the first equation:

Given system of equations:

3x - 4y = 11

y + 3x = 1

Step 1: Solve the second equation for y:

y = 1 - 3x

Step 2: Substitute the value of y from equation (2) into equation (1):

3x - 4(1 - 3x) = 11

Now, let's solve for x:

3x - 4 + 12x = 11

Combine like terms:

15x - 4 = 11

Step 3: Solve for x:

15x = 11 + 4

15x = 15

x = 15 / 15

x = 1

Step 4: Now that we have the value of x, we can find y using equation (2):

y = 1 - 3(1)

y = 1 - 3

y = -2

So, the solution to the system of equations is x = 1 and y = -2.

Answer:

I believe it is D

Step-by-step explanation:

The entire equation y=nx-d means that d is the fee Kyle pays the school. SO that means that nx is the amount of money he earns from the people attending a yoga class.

Term nx represents the total money Kyle collects from people attending the class.

" Linear equation in one variable represents straight line and it is a equation in one variable in which degree of the given variable is equals to one. General form is written as ax + b =0."

According to the question,

x represents fees paid by each person for yoga class.

Condition is Kyle has to pay a fee for the use of gym.

It mean gym fees would be deducted from her earned fees from yoga class.

Therefore , d represents gym fee.

n represents number of people comes for yoga class.

From the given condition it is a linear equation in one variable,

Therefore, nx represents amount Kyle collects from people attending the class.

Answer:

y = -2x - 3

Step-by-step explanation:

First, find slope (m) of the line using two points (0, -3) and (1, -5):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-3)}{1 - 0} = \frac{-2}{1} = -2 [/tex]

The line intercepts the y-axis at y = -3. Therefore the y-intercept (b) of the line = -3.

To write the equation that represents the line, substitute m = -2, and b = -3 into y = mx + b.

Thus:

y = -2x + (-3)

y = -2x - 3

Average attendance in 2003 = 1800

Average attendance in 2004 = 500

Decrease in attendance = 1800 - 500 = 1300

Decrease percentage in attendance

They will go 6 days on vacation.

Step-by-step explanation:

Given that the Carter family wants to go on vacation with a budget of $ 2700, of which $ 1000 will be used exclusively for food, and for each day of stay $ 275 will be spent, the formula to obtain the number of days they can spend on vacation is following:

1000 + 275n = 2700

275n = 2700 - 1000

n = 1700/275

n = 6.18

Therefore, with this amount, the Carters will be able to spend 6 days on vacation, and they will have money left over.
