The forces exerted on an object are shown.
A box has an arrow pointing right labeled 6 N and an arrow pointing left labeled F.
If the object moves right, which of the following is a possible value of F?
5 N
6 N
7 N
8 N
Answer:
So you have a box, with weight Wb and you have a right force of 6N and a left force of Fl
With sum of forces you get that to maintain equilibrium the force Fl must be 6 therfore to maintain moving right the left force must be 5N
Rate positively and give brainlist
Answer:
The answer is 5n
Step-by-step explanation:
Since the force on the right would have to be greater, and the force on the right is 6n, the left force would have to be less. Therefore, the answer is 5n.

Solve the following system of equations using elimination.
5x+y=24
-5x-4y=-56
Answer:
x = 8/3 and y = 32/3
Step-by-step explanation:
Add the two equations, getting -3y = -32, thus y = 32/3
Sub for y in first equation, getting 5x + 32/3 = 24
5x = 40/3
x = 8/3
Find the area of the surface. The part of the surface z = xy that lies within the cylinder x2 + y2 = 36.
Answer:
Step-by-step explanation:
From the given information:
The domain D of integration in polar coordinates can be represented by:
D = {(r,θ)| 0 ≤ r ≤ 6, 0 ≤ θ ≤ 2π) &;
The partial derivates for z = xy can be expressed as:
[tex]y =\dfrac{\partial z}{\partial x} , x = \dfrac{\partial z}{\partial y}[/tex]
Thus, the area of the surface is as follows:
[tex]\iint_D \sqrt{(\dfrac{\partial z}{\partial x})^2+ (\dfrac{\partial z}{\partial y})^2 +1 }\ dA = \iint_D \sqrt{(y)^2+(x)^2+1 } \ dA[/tex]
[tex]= \iint_D \sqrt{x^2 +y^2 +1 } \ dA[/tex]
[tex]= \int^{2 \pi}_{0} \int^{6}_{0} \ r \sqrt{r^2 +1 } \ dr \ d \theta[/tex]
[tex]=2 \pi \int^{6}_{0} \ r \sqrt{r^2 +1 } \ dr[/tex]
[tex]= 2 \pi \begin {bmatrix} \dfrac{1}{3}(r^2 +1) ^{^\dfrac{3}{2}} \end {bmatrix}^6_0[/tex]
[tex]= 2 \pi \times \dfrac{1}{3} \Bigg [ (37)^{3/2} - 1 \Bigg][/tex]
[tex]= \dfrac{2 \pi}{3} \Bigg [37 \sqrt{37} -1 \Bigg ][/tex]

Solve the equation and check your solution.
3x − 6 = 4(2 − 3x) − 8x
Answer:
x = 14/23
Step-by-step explanation:
3x − 6 = 4(2 − 3x) − 8x
3x − 6 = 8-12x − 8x
3x=14-20x
23x=14
x= 14/23
3(14/23)-6=4(2 − 3(14/23) − 8(14/23)
And solve hope this helps. Remember to isolate the variable when finding x for next time.
The solution to the given equation is x = 14/23.
To solve the equation 3x - 6 = 4(2 - 3x) - 8x, we will simplify and solve for x:
First, let's distribute 4 to the terms inside the parentheses on the right side of the equation:
3x - 6 = 8 - 12x - 8x
Next, let's combine like terms on the right side of the equation:
3x - 6 = -20x + 8
Now, let's bring all the x terms to one side of the equation by adding 20x to both sides:
3x + 20x - 6 = -20x + 20x + 8
This simplifies to:
23x - 6 = 8
Next, let's isolate the x term by adding 6 to both sides:
23x - 6 + 6 = 8 + 6
This simplifies to:
23x = 14
Finally, divide both sides by 23 to solve for x:
x = 14/23
So, the solution to the equation is x = 14/23.
To check the solution, substitute x = 14/23 back into the original equation:
3(14/23) - 6 = 4(2 - 3(14/23)) - 8(14/23)
This simplifies to:
42/23 - 6 = 8/23 - 12(14/23) - 112/23
-132/23 = -132/23
Both sides of the equation are equal, confirming that x = 14/23 is the correct solution.

What is the area of this quadrilateral?
10
OA. 130 square feet
B. 50 square feet
)C. 80 square feet
O D. 30 square feet
Answer:
C. 80
Step-by-step explanation:
5x10x.5=25
25x2=50
3x10=30
50+30=80
Answer:
C
Step-by-step explanation:
Split the shape into normal shapes such as a rectangle and two triangles
use there formulas for area for each shape
rectangle L x W
10 x 3 = 30
for triangles it’s side a times the base divided by 2
5 x 10 / 2 = 25
so it’s 50 because there is two triangles
add 50 and 30
so it’s 80ft so C
The crisis in the housing market during the most recent economic recession led to lower vacancy rates in the apartment industry. This, in turn, has resulted in an increase in monthly rents for apartments. Suppose a random sample of 40 apartments had an average rent of $1,090. Assume the standard deviation for the population of apartment rents is $260. Determine the 98% confidence interval for this sample.
Answer:
(994.37, 1185.62)
Step-by-step explanation:
Given that :
Mean (m) = 1090
Standard deviation (s) = 260
Samole size (n) = 40
α = 98%
Using the relation :
Confidence interval = mean ± Error
Error = Zcritical * (standard deviation / sqrt (n))
Zcritical at 98% = 2.326
Error = 2.326 * (260 / sqrt(40))
Error = 95.620951
Hence,
Confidence interval :
Lower boundary = 1090 - 95.620951 = 994.379049
Upper boundary = 1090 + 95.620951 = 1185.620951
(994.37, 1185.62)
a graph represents a relation that is also a function if only and if every ___ intersects the graph ___ once
Answer:
A graph represents a relation that is also a function if only and if every vertical line intersects the graph at most once.
Step-by-step explanation:
The vertical line test should be used to get an idea about the nature of a graph whether it represents a function or not. A vertical line must not intersect the graph multiple times as it would violate the definition of a function.
If a vertical line intersects the graph multiple times, it means the graph is having the same repeated inputs, which is against the definition of a function. A function can not have repeated input values.
Thus, we conclude that a graph represents a relation that is also a function if only and if every vertical line intersects the graph at most once.

The value of y varies directly with x. When y= 80, x= 2. What is the value of y when x is 2?
100
O 64
O 156
O 400
Answer:
I just know something that answer is 156
I need help with this
Answer: 500
Step-by-step explanation: use the equation y=mx+b.
B = cost of the plan per month
X = number of minutes
M = price per minute
The first plan is a flat rate of $25 a month. Whereas the second is $10 plus $0.05 a minute.
Plug in the answers until you get a price that is equal to $25.
Y = 0.05(300) + 10
Y = 25
therefore after 300 minutes the other plan is cheaper
4(x-3)=9 what is the first step
Answer:
x= 5.25
Step-by-step explanation:
You have to get x alone, so do inverse operations.
(Basically, reverse what it is)
4(x-3)=9
divide 4 by both sides to get rid of 4 on left side
9/4 = 2.25
(x-3) = 2.25
Now add 3 to both sides, to get x alone
2.25 + 3 = 5.25
x=5.25
Check work
4(5.25-3) = 9
4(2.25) = 9
9=9

HELP THIS IS DUE IN ONE HOUR I NEED A GOOD ANSWER! Each sales associate at an electronics store has a choice of the two salary options shown below.
• $115 per week plus 9.5% commission on the associate’s total sales
• $450 per week with no commission
a. The average of the total sales amount for each associate last year was $125,000. Based on this average, which salary option would result in a higher salary?
b. What is the difference between the two salary options?
Answer:
A) The best option would be a fixed weekly salary of $ 450.
B) The difference between the two options is $ 106.64.
Step-by-step explanation:
A) To determine which option would result in a better salary, knowing that on the one hand you can have a fixed salary of $ 450 per week without commission, while on the other you can have a salary of $ 115 per week plus a commission of 9.5% on the total sales of Each associate, knowing that the average annual sales of each associate in the last year was $ 125,000 and that each year has 52 weeks, the following calculation must be made:
125,000 / 52 = Average sales per week
2,403.84 = Average sales per week
2,403.84 x 0.095 = Weekly commission
228.36 = Weekly commission
228.36 + 115 = Weekly salary
343.36 = Weekly salary
Therefore, the best option would be a fixed weekly salary of $ 450.
B) The difference between both options arises from the subtraction between each amount received by the worker, that is:
450 - 343.36 = X
106.64 = X
Therefore, the difference between the two options is $ 106.64.
