A person pulls horizontally with a force of 64 N on a 14-kg box. There is a force of friction between the box and the floor of 36 N. Find the acceleration of the box in m/s2 Show your work
The net force is what remains of the pull when we subtract the friction force:
[tex]F = 64-36 = 28N[/tex]
Now, use the law
[tex]F=ma[/tex]
and solve it for the acceleration
[tex]a = \dfrac{F}{m}[/tex]
to get the result:
[tex]a = \dfrac{28}{14}=2[/tex]
Answer:
2 m/s²
Step-by-step explanation:
F = applied force in the horizontal direction = 64 N
f = frictional force acting between the box and the floor = 36 N
m = mass of the box = 14 kg
a = acceleration of the box = ?
Force equation along the horizontal direction is given as
F - f = ma
Inserting the values
64 - 36 = 14 a
28 = 14 a
a = [tex]\frac{28}{14}[/tex]
a = 2 m/s²
Find the range of the function f of x equals the integral from negative 6 to x of the square root of the quantity 36 minus t squared
[tex]f(x)=\displaystyle\int_{-6}^x\sqrt{36-t^2}\,\mathrm dt[/tex]
The integrand is defined for [tex]36-t^2\ge0[/tex], or [tex]-6\le t\le6[/tex], so the domain should be the same, [tex]-6\le x\le6[/tex].
When [tex]x=-6[/tex], the integral is 0.
The integrand is non-negative for all [tex]x[/tex] in the domain, which means the value of [tex]f(x)[/tex] increases monotonically over this domain. When [tex]x=6[/tex], the integral gives the area of the semicircle centered at the origin with radius 6, which is [tex]\dfrac\pi26^2=18\pi[/tex], so the range is [tex]\boxed{0\le f(x)\le 18\pi}[/tex].
The range of the function f(x) is the integral from -6 to x of the square root of the quantity 36 minus t squared is [0, 6*π] because the total area of the semicircle is the maximum value.
Explanation:The function f(x) is the integral from -6 to x of the square root of the quantity 36 minus t squared. This is a known geometrical shape, which is a semicircle with radius 6. To find the range of this function, we need to know the possible outcomes of this function. In general, for a semicircle of radius r, the values of the square root of the quantity r squared minus t squared will vary from 0 to r, both inclusive. So, if you consider the function from -6 to 6, the range would be [0, 6*π] because the total area of the semicircle is the maximum value.

Sarah and Max must decide how to split up 8 cookies. Sarah (we'll call her player 1) makes a proposal to Max (we'll call him player 2), of how many cookies each of them should receive. We assume that each kid is trying to maximize the amount of cookies they receive, and that they must follow the rules below: If Max accepts the proposal, they split the cookies according to that agreement. If Max doesn't accept the proposal, he tells their dad. Their dad will eat 4 of the cookies and then split the rest evenly. Assume that if Max is indifferent between accepting and rejecting, he will always accept the offer. How many cookies will Sarah offer Max
She would offer to split the cookies evenly, so they each get 4.
If she offered Max less than 4, he would not accept and their dad would eat half, so each person would only get 2 cookies each.
If she offered Max more than 4, then she doesn't maximize the amount she would get.

When studying radioactive material, a nuclear engineer found that over 365 days, 1,000,000 radioactive atoms decayed to 973 comma 635 radioactive atoms, so 26 comma 365 atoms decayed during 365 days. a. Find the mean number of radioactive atoms that decayed in a day. b. Find the probability that on a given day, 51 radioactive atoms decayed.
Answer:
A. number of decayed atoms = 73.197
Step-by-step explanation:
In order to find the answer we need to use the radioactive decay equation:
[tex]N(t)=N0*e^{kt}[/tex] where:
N0=initial radioactive atoms
t=time
k=radioactive decay constant
In our case, when t=0 we have 1,000,000 atoms, so:
[tex]1,000,000=N0*e^{k*0}[/tex]
[tex]1,000,000=N0[/tex]
Now we need to find 'k'. Using the provied information that after 365 days we have 973,635 radioactive atoms, we have:
[tex]973,635=1,000,000*e^{k*365}[/tex]
[tex]ln(973,635/1,000,000)/365=k[/tex]
[tex] -0.0000732=k[/tex]
A. atoms decayed in a day:
[tex]N(t)=1,000,000*e^{-0.0000732t}[/tex]
[tex]N(1)=1,000,000*e^{-0.0000732*1}[/tex]
[tex]N(1)= 999,926.803[/tex]
Number of atoms decayed in a day = 1,000,000 - 999,926.803 = 73.197
B. Because 'k' represents the probability of decay, then the probability that on a given day 51 radioactive atoms decayed is k=0.0000732.
A company manufactures bicycles at a cost of $50 each. If the company's fixed costs are $700, express the company's costs as a linear function of x, the number of bicycles produced.
Answer:
[tex]y = 700 + 50x[/tex]
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
If the company has a fixed cost (fixed being a keyword) of $700, then that cost will be a steady value before they even start to manufacture the bicycles. Afterwards they have to spend $50 on each bicycle they produce. Since we do not know the amount of bicycles that have been produced we can use the variable x to represent this.
[tex]y = 700 + 50x[/tex]
The equation above states that the company pays $700 plus $50 for every bike produced which comes out to a total of y.

We are given three coins: one has heads in both faces, the second has tails in both faces, and the third has a head in one face and a tail in the other. We choose a coin at random, toss it, and it comes head. What is the probability that the opposite face is tails?
Answer: 0.33
Step-by-step explanation:
Let,
E1 be the coin which has heads in both facesE2 be the coin which has tails in both facesE3 be the coin which has a head in one face and a tail in the other.In this question we are using the Bayes' theorem,
where,
P(E1) = P(E2) = P(E3) = [tex]\frac{1}{3}[/tex]
As there is an equal probability assign for choosing a coin.
Given that,
it comes up heads
so, let A be the event that heads occurs
then,
P(A/E1) = 1
P(A/E2) = 0
P(A/E3) = [tex]\frac{1}{2}[/tex]
Now, we have to calculate the probability that the opposite side of coin is tails.
that is,
P(E3/A) = ?
∴ P(E3/A) = [tex]\frac{P(E3)P(A/E3)}{P(E1)P(A/E1) + P(E2)P(A/E2) + P(E3)P(A/E3) }[/tex]
= [tex]\frac{(1/3)(1/2)}{(1/3)(1) + 0 + (1/2)(1/3)}[/tex]
= [tex]\frac{1}{6}[/tex] × [tex]\frac{6}{3}[/tex]
= [tex]\frac{1}{3}[/tex]
= 0.3333 ⇒ probability that the opposite face is tails.
Given a double-headed coin, a double-tailed coin, and a regular coin, the probability that the opposite face is tails after tossing a head is 33.33%, assuming we picked one coin randomly and tossed it to see a head.
The student is asking about a problem involving conditional probability, with the specific condition that one of the sides that came up is a head. We are given three coins: a double-headed coin, a double-tailed coin, and a regular coin. The aim is to calculate the probability that the opposite face is tails given that the tossed coin shows heads.
First, we need to consider the total number of heads that can come up when choosing any coin. This yields two heads from the double-headed coin, and one head from the regular coin, resulting in three possible heads. However, only the regular coin has a tail on the opposite side.
Consequently, the probability that the opposite face is tails given that a head has been tossed is 1 out of 3, or 33.33%.
Consider the sequence 1, 5, 12, 22, 35, 51, . . . (with a0 = 1). By looking at the differences between terms, express the sequence as a sequence of partial sums. Then find a closed formula for the sequence by computing the nth partial sum.
The given sequence can be expressed as a sequence of partial sums by finding the differences between terms and adding them to the previous term. The closed formula for the nth partial sum is Sn = n/2(3n - 1), where Sn represents the nth partial sum.
Explanation:To express the given sequence as a sequence of partial sums, we can find the differences between consecutive terms:
5 - 1 = 4
12 - 5 = 7
22 - 12 = 10
35 - 22 = 13
51 - 35 = 16
From these differences, we can observe that each term in the sequence is obtained by adding the difference to the previous term. Therefore, the sequence can be written as a sequence of partial sums:
1, 1+4, 1+4+7, 1+4+7+10, 1+4+7+10+13, ...
To find a closed formula for the nth partial sum, we can use the formula for the sum of an arithmetic series:
Sn = n/2(a1 + an), where Sn represents the nth partial sum, a1 is the first term, and an is the nth term.
For the given sequence, a1 = 1 and the difference between consecutive terms is 3, so the nth term can be represented as an = 1 + 3(n-1). Substituting these values into the formula, we get:
Sn = n/2(1 + 1 + 3(n-1)) = n/2(2 + 3(n-1)) = n/2(3n - 1).

WHAT IS THE PROBABILITY OF GETTING EITHER JACK OR A THREE WHEN DRAWING A SINGLE CARD FROM A DECK OF 52 CARDS? WHAT IS THE PROBABILITY THAT THE CARD IS EITHER A JACK OR A THREE?
Answer:
2/13
Step-by-step explanation:
there are 4 jacks and 4 threes in a standard poker deck.
4+4 is 8
8/52=2/13
The probability of drawing either a Jack or a three from a standard deck of 52 cards is 2/13, because there are 8 such cards in a deck and the total number of cards in the deck is 52.
The question asks for the probability of drawing either a Jack or a three from a standard deck of 52 cards. To solve this, we need to count how many Jacks and threes there are in a deck. Since each suit (hearts, diamonds, clubs, and spades) includes one Jack and one three, there are 4 Jacks and 4 threes in a standard deck. Therefore, there are 8 cards that satisfy the condition (either a Jack or a three).
Since the total number of cards in the deck is 52, the probability of drawing either a Jack or a three is calculated as the number of favorable outcomes (drawing a Jack or a three) divided by the total number of outcomes (drawing any card from the 52-card deck). Thus, the probability is:
Probability = (Number of Jacks + Number of threes) / Total number of cards = (4 + 4) / 52 = 8 / 52 = 2 / 13
Therefore, the probability of drawing either a Jack or a three from a standard deck of 52 cards is 2/13.

Since, the monthly payment formula is,
[tex]P=\frac{PV(r)}{1-(1+r)^{-n}}[/tex]
Where, PV is the present value of the loan,
r is the rate per month,
n is number of months,
Here,
PV = $ 25,000,
Annual rate = 5.2 % = 0.052 ⇒ Monthly rate, r = [tex]\frac{0.052}{12}[/tex]
( 1 year = 12 months )
P = $ 295,

Step-by-step explanation:
Consider the provided information:
It is provided that monthly payment is $175, interest is 7% and time is 11 years.
The formula for the future value of the annuity due is:
[tex]FV of Annuity Due = (1+r)\times P[\frac{(1+r)^{n}-1}{r}][/tex]
Now, substitute P = 175, r = 0.07 and t = 11 in above formula.
[tex]FV of Annuity Due = (1+0.07)\times 175[\frac{(1+0.07)^{11}-1}{0.07}][/tex]
[tex]FV of Annuity Due = (1.07)\times 175[\frac{1.10485}{0.07}][/tex]
[tex]FV of Annuity Due = 187.5(15.7835)[/tex]
[tex]FV of Annuity Due = 2955.4789[/tex]
Hence, the future value of the annuity due to the nearest cent is $2956.
what are the values of x and y such that ABCD=PQRS?
Answer:
T(x, y) = T(0, -8)
Step-by-step explanation:
The first reflection can be represented as ...
(x, y) ⇒ (-x, y)
__
The rotation about the origin is the transformation ...
(x, y) ⇒ (-x, -y)
so the net effect of the first two transforms is ...
(x, y) ⇒ (x, -y)
__
Then the reflection across y=4 alters the y-coordinate:
(x, y) ⇒ (x, 8-y)
so the net effect of the three transforms is ...
(x, y) ⇒ (x, 8+y)
__
In order to bring the figure back to place, we must translate it down 8 units using ...
(x, y) ⇒ (x, y-8) . . . . net effect: (x, y) ⇒ (x, (8+y)-8) = (x, y)
The translation is by 0 units in the x-direction and -8 units in the y-direction.
Find an equation of the vertical line through (-6, -9) in the form ax+ byc, where a, b, and c are integers with no factor common to all three, and az0. The equation is (Type an equation.)
Answer:
The equation of the vertical line through (-6, -9) is 1x+0y=-6.
Step-by-step explanation:
The standard form of a line is
[tex]ax+by=c[/tex]
where a, b, and c are integers with no factor common to all three, and a>0.
If a vertical line passes through the point (a,b), then the equation of vertical line is x=a.
It is given that the vertical line passes through the point (-6,-9). Here a=-6 and b=-9, so the equation of the vertical line through (-6, -9) is
[tex]x=-6[/tex]
[tex]1x+0y=-6[/tex]
The standard form of the line is 1x+0y=-6. where the value of a,b c are 1, 0, -6 respectively.
Therefore the equation of the vertical line through (-6, -9) is 1x+0y=-6.
Write equations for the vertical and horizontal lines passing through the point . (7,5)
A horizontal line is a line where all of the [tex]y[/tex] values are the same. In this case, [tex]\boxed{y=5}[/tex], so that is the equation.
A vertical line is where all of the [tex]x[/tex] values are the same. Here, [tex]\boxed{x=7}[/tex], so that's the equation.
Answer:
see below
Step-by-step explanation:
A horizontal line has the same y value and has a constant y value
y=5
A vertical line has the same x value and has a constant x value
x=7
6. Let A and B be nxn matrices . Compute (A + B) (A + B). Explain all steps.
Answer:
(A+B)(A+B)=A.A+B.A+A.B+B.B
Step-by-step explanation:
Given that matrices A and B are nxn matrices
We need to find (A+B)(A+B)
For understanding the multiplication of matrices let'take A is mxn and B is pxq matrices,we can multiple only when n=p,so our Ab matrices will be mxq.
We know that that in matrices AB is not equal to BA.
Now find
(A+B)(A+B)=A.A+B.A+A.B+B.B
So from we can say that (A+B)(A+B) is not equal to A.A+2B.A+B.B because AB is not equal to BA in matrices.
So (A+B)(A+B)=A.A+B.A+A.B+B.B
A Game of Thrones fan predicts there is a 70% chance that her favorite character will survive the next season and a 75% chance that her second favorite character will die. There is also a 16% chance that both characters will die. What’s the probability that the second character will die given that the first character dies? What kind of probability is this called?
Final answer:
The probability that the second character will die given that the first character dies is 53.33%. This is known as conditional probability.
Explanation:
To find the probability that the second character will die given that the first character dies, we use the concept of conditional probability.
The formula for conditional probability is P(B|A) = P(A and B) / P(A), where P(B|A) is the probability of event B occurring given that event A has occurred, P(A and B) will be the probability of both events A and B occurring, and P(A) is the probability of event A occurring.
In this scenario, event A is the first character dying, and event B is the second character dying. The student has already stated there is a 70% chance that the first character will survive, which means there is a 30% (100% - 70%) chance that the first character will die.
They've also stated a 16% chance that both characters will die. Applying the formula gives us P(B|A) = P(A and B) / P(A) = 0.16 / 0.30 = 0.5333, or 53.33%.
Therefore, the probability that the second character will die given that the first character dies is 53.33%. This kind of probability is called conditional probability.
