A bag weighing 80 N rests on a horizontal surface. The coefficient of static friction between the bag and the surface is 0.4, and the coefficient of kinetic friction is 0.2. What minimum horizontal force must be applied to keep the bag moving at constant velocity once it has started to move?
Answer:
The minimum horizontal force that must be applied to keep the bag moving at constant velocity once it has started to move is 16 newtons.
Step-by-step explanation:
According to the First and Second Newton's Laws, an object has net force of zero when it is at rest or moves at constant velocity. Given that bag rests on a horizontal surface, the equation of equilibrium is:
[tex]\Sigma F = P - f = 0[/tex] (Eq. 1)
Where:
[tex]P[/tex] - Horizontal force exerted on the bag, measured in newtons.
[tex]f[/tex] - Kinetic friction force, mesured in newtons.
From (Eq. 1), we get that horizontal force is:
[tex]P = f[/tex]
On the case of a horizontal surface, normal force exerted from ground on the bag and kinetic friction force is:
[tex]f = \mu_{k}\cdot W[/tex] (Eq. 2)
Where:
[tex]\mu_{k}[/tex] - Kinetic coefficient of friction, dimensionless.
[tex]W[/tex] - Weight of the bag, measured in newtons.
Then we eliminate kinetic friction force by equalizing (Eqs. 1, 2):
[tex]P = \mu_{k}\cdot W[/tex]
If we know that [tex]\mu_{k} = 0.2[/tex] and [tex]W = 80\,N[/tex], then the horizontal force that must be applied to is:
[tex]P =0.2\cdot (80\,N)[/tex]
[tex]P = 16\,N[/tex]
The minimum horizontal force that must be applied to keep the bag moving at constant velocity once it has started to move is 16 newtons.

find the value of the height of the tree.
Answer:
20 ft
Step-by-step explanation:
First we must find out what the scale factor is.
26 / 6.5 = 4
the scale factor is 4.
Now we must multiply 5 by 4 to find x.
5 * 4 = x
20 = x
x = 20
The height of the tree is 20 ft.
Jacques, an artisan cheese maker, collects data on every step of the cheese-making process for each batch he makes. Jacques noticed that the daily high temperature in his shop on the day he made a batch of cheese was related to the pH of the cheese the next morning. He computed the correlation between the daily high temperature and the pH of the cheese to be −0.64 . What information does the correlation provide about the relationship between the daily high temperature and the pH of the cheese?
Answer:
The information is
The daily temperature of the shop increases while the pH of the cheese decreases
Step-by-step explanation:
From the question we are told that
The correlation between the daily high temperature and the pH of the cheese to be −0.64
Generally the information this negative correlation provides a about the relationship between the daily high temperature and the pH of the cheese is that as the daily temperature of the shop increases that pH of the cheese decreases
y=3x-5 identify y intercept within equation
Answer: -5
Step-by-step explanation: alrite so when u graph it, the line crosses -5 on the y axis

You deposit $900 in a savings account that earns a simple interest rate of 4.5% per year. You calculate you will earn $1215 in interest over 3 years. Is your answer reasonable?
A. Yes; the interest will be much less than the total in the account
B. No; the interest will be much less than the total in the account.
C. No; the interest will be more than the total in the account.
D. Yes; the interest will be more than the total in the account.
Answer:
a..
Step-by-step explanation:
yes the interest will be much less than total than the account
The answer is not reasonable because the interest will be much less than the total in the account.
In order to determine if the answer is reasonable, we have to determine the simple interest that would be earned and the total amount in the account.
Simple interest = amount deposited x time x interest rate
$900 x 0.045 x 3 = $121.50
The total amount in the account in three years = amount deposited + interest earned
$900 + $121.50 = $1021.50.

B'
(-2,1)
C'
(-5,2)
Do you see what happened. All the values for x become - values because you are moving an equal distance in the -x direction
The sand pit has a width of 2.56meters and a length of 8.75meters. Just in case it rains, the principal wants to cover the sand pit with a piece of plastic the night before the event. How many square meters of plastic will the principal need to cover the sand pit
Answer:
The answer is below
Step-by-step explanation:
The piece of plastic needed to cover the sand pit is the same as the area of the sand pit. Since the sand pit has a width of 2.56meters and a length of 8.75meters, it means that the sand pit is rectangular in shape. The area of the sand pit is given by the formula:
Area = length × width
Area = 2.56 meters × 8.75 meters
Area = 22.4 m²
The plastic needed to cover the sand pit needs to have an area of 22.4 m²

Dylan and his friends are going into a bakery. How much would it cost to buy 1 cookie and 5 brownies if each cookie costs $0.50 and each brownie costs $2.25? How much would it cost to buy 11 cookies and 55 brownies if each cookie cost \$c$c and each brownie cost \$b?$b?
Answer:
a)$ 11.75
b) $ 129.25
Step-by-step explanation:
Dylan and his friends are going into a bakery.
Each cookie costs $0.50 and each brownie costs $2.25?
a) How much would it cost to buy 1 cookie and 5 brownies
1 × $0.50 + 5 × $2.25
= $0.50 + 11.25
= $ 11.75
b) How much would it cost to buy 11 cookies and 55 brownies
11 × $0.50 + 55 × $2.25
= $5.5 + $123.75
= $ 129.25

You must show all your working.
Answer:
5/7
Step-by-step explanation:
You can convert them to fractions to answer:
7/5=1.4
5/7=0.714
7/5 is 0.4 away from 1, while 5/7 is 0.3 away.
Answer:
5/7 is closer
Step-by-step explanation:
7/5= 49/35=1 14/35
5/7= 25/35
7/5 is 14/35 away from one whereas 5/7 is 10/35 away.
The system of linear equations -2x+y=8 and -3x-y=7
Answer: x=-3, y=2
Step-by-step explanation: -2x+y=8 + -3x-y=7 and you get x=-3 then you put that in to x and pick one of the beginning equations i chose to put -3 in to -2(-3)+y=8 and got 6+y=8 then you subtract the 6 on both sides and should get y=2
Answer:
(-3,2)
Step-by-step explanation:
You can solve it by various methods. These two equations can be solved simultaneously or by matrix method, or even by graphing
Simultaneous is easier so lets get started.
1st equation : [tex]-2x+y=8[/tex]
2nd equation: [tex]-3x-y=7[/tex]
We solve it by using the substitution method which means there are two variables x and y and we substitute one variable in form of another variable.
Like, take the 1st equation
[tex]-2x+y=8\\y=8+2x[/tex]
the equation is arranged in a different manner but its the same thing.
This new equation becomes our new third equation and now we simply put our third equation in our 2nd equation. Like this, take the 2nd equation and substitute it with our 3rd third equation
[tex]-3x-y=7\\-3x-7=y\\-3x-7=8+2x\\-3x-2x=8+7\\-5x=15\\x=-3[/tex]
we get x=-3 and then we put the value of x and in our third equation to get the value of y or we can simply put it in any equation 1st , 2nd , 3rd it will give the same answer. I chose third.
[tex]y=8+2x\\y=8+2(-3)\\y=8-6\\y=2[/tex]
The solution set of our system of linear equations is
(-3,2)
