Answer:

  13 lb

Step-by-step explanation:

The horizontal component of the force is the magnitude of the force multiplied by the cosine of the angle with the horizontal.

  (16 lb)·cos(35°) ≈ 13.1 lb ≈ 13 lb

Answer:

b.13 lb

Step-by-step explanation:

We are given that  a boy pulls his sled with a rope .

The rope makes an angle with horizontal =[tex]35^{\circ}[/tex]

If a pull on the rope is needed to move the sled=16 pounds

We have to find the horizontal component of force

We know that horizontal component force=[tex]fcos\alpha[/tex]

Therefore, we have f=16 pound

Then, horizontal component of force=[tex]16cos 35^{\circ}[/tex]

Horizontal component of force=[tex]16\times 0.819=13.1lb[/tex]

Hence, horizontal component of force=13 lb

Answer:b.13 lb

Answer:

Yes.

Step-by-step explanation:

To see if h is a factor of f, we can use the factor theorem.

h(x)=x-3 has a zero at x=3 because h(3)=3-3=0.

So we want to see if the zero of h is a zero of f.

Is x=3 a zero of f?

You can check using synthetic division or just plug in 3.

Let's do both.

If you use synthetic you are trying to see if you get a remainder of 0.

If you plug it in you are trying to see if you get 0 as the output when plugging your input 3.

Let's do synthetic first:

Since we are checking to see if x=3 is a zero, that will go on the outside:

3 |  1   -1  -1   -15

 |        3   6    15

- ------------------------

     1    2   5     0

So yep the remainder is 0 so the answer is yes.

Let's plug it in:

f(3)=3^3-3^2-3-15

f(3)=27-9-3-15

f(3)=18-3-15

f(3)=15-15

f(3)=0

The result is 0 so the answer is yes.

60°=CAD

Answer:

A) (2, -1/2)

Step-by-step explanation:

Start with one equation and isolate a variable:

4x - 4y = 10

4x - 4x - 4y = 10 - 4x

-4y = 10 - 4x

-4y/-4 = 10/-4 - 4x/-4

y = -2 1/2 + x

Now plug this in for y in the other equation:

3x + 2(-2 1/2 + x) = 5

3x - 5 + 2x = 5

5x - 5 = 5

5x - 5 + 5 = 5 + 5

5x = 10

5x/5 = 10/5

x = 2

Right here we can tell your answer is A since it is the only one with 2 as the x-value

Answer:

Widow's Share = Rs 500.05

Son's share = Rs 1400.14

Step-by-step explanation:

Property = 4000.40

Widow get share = 0.125

So, Share of Widow = 0.125 * 4000.40

Widow's Share = Rs 500.05

Remaining Property = 4000.40 - 500.05

Remaining Property = 3500.35

Son's share = 0.4 * 3500.35

Son's share = Rs 1400.14

To solve this problem, we will follow these steps:
1. Calculate the widow's share of the property.
2. Determine the remainder of the property after the widow has received her share.
3. Calculate the son's share of the remainder of the property.
Step 1: Calculate the widow's share.
The widow gets 0.125 (or 12.5%) of the total property. The total property is valued at 4000.40 units (where the unit could be in rupees, dollars, etc.).
Widow's share = Total property * Widow's share percentage
              = 4000.40 * 0.125
Let's calculate that:
Widow's share = 4000.40 * 0.125
              = 500.05
So, the widow gets 500.05 units.
Step 2: Determine the remainder of the property.
Now, subtract the widow's share from the total property to find out how much is left for the son to receive his share from.
Remainder of property = Total property - Widow's share
                      = 4000.40 - 500.05
Let's calculate that:
Remainder of property = 4000.40 - 500.05
                      = 3500.35
Now we have 3500.35 units remaining after the widow has received her share.
Step 3: Calculate the son's share.
The son gets 0.4 (or 40%) of the remainder of the property.
Son's share = Remainder of property * Son's share percentage
            = 3500.35 * 0.4
Let's calculate that:
Son's share = 3500.35 * 0.4
            = 1400.14
So, the son gets 1400.14 units.
To summarize, the widow receives 500.05 units of the property, and the son receives 1400.14 units of the property after the widow has received her share.

Answer:

The last option is correct for two independent events.

P(A and B) = P(A) P (B)

And P(B and A) = P(B) P(A) which is equal. And other three cases are false.

P(AB) = P(BA) is true.

If outcomes of an event doesn't affect the outcomes of other event, the the events are called independent events, i.e. they are independent to each other.

For two independent events,

P(AB) = P(A)P(B)

Also, P(BA) = P(B)P(A)

And,  P(A)P(B) = P(B)P(A)

Answer:

x = 5.34

Step-by-step explanation:

The reference angle is 24 degrees.  I'm sure you are aware from the square at the other base angle that is a right triangle.  Right triangles have ratios by which we can determine missing side and angle measures.  The sin of a reference angle has a ratio that is side opposite/hypotenuse.  The cos of a reference angle has a ratio that is side adjacent/hypotenyse.  The tan of a reference angle has a ratio that is side opposite/side adjacent.

We need to decide which of these fits our needs according to the angle and sides we are given and need to find.  We have the reference angle as 24 degrees, we have the side adjacent to this angle as 12.  We are looking for x, which is the side opposite the reference angle.  Looking to what our definitions are for each ratio, the sides opposite and adjacent are defining the tan of the reference angle.  Setting up the ratio then looks like this:

[tex]tan(24)=\frac{x}{12}[/tex]

Multiply both sides by 12 to get

12 tan(24) = x

Do this on your calculator in DEGREE mode to get that

x = 5.342744224

[tex] x=2 \pm \frac{\sqrt{6}}{2}[/tex]

So let's put both of these into out calculator

Amount of expenditure to be shown on the income statement = 0 and Income from the reversal of additional balance = $200

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

Given that the Allowance for Uncollected Accounts is at 2% based on the percentage of sales method, the closing amount for the current year must be 2% of credit sales.

Current year credit sales = $140,000

Allowance for Uncollected Accounts = $140,000 × 2% = $2,800

the current amount of Allowance for Uncollected Accounts is $3,000, it is already $200 in excess of the threshold ($3000 - $2800), hence it must be reversed by $200.

Amount of expenditure to be shown on the income statement = 0.

Income from the reversal of additional balance = $200

Final answer:

To calculate the expense for uncollectibles using the percent-of-sales method, multiply the net credit sales by the estimated percentage of uncollectibles. For Millford Company, this calculation is $140,000 * 2%, resulting in an expense of $2,800, ignoring the existing allowance balance.

Explanation:

The student has asked how to calculate the expense to report on the income statement for uncollectibles using the percent-of-sales method. Millford Company estimates that 2% of their net credit sales of $140,000 will be uncollectible. To find the uncollectible expense, you multiply the total net credit sales by the estimated percentage, which is $140,000 * 2% = $2,800. Since the Allowance for Uncollectible Accounts has a prior credit balance of $3,000, the current period's expense recognized in the income statement is calculated by adjusting for this existing balance. However, if the question simply asks for the expense amount based on current sales, it ignores the pre-adjustment balance and focuses solely on the estimated uncollectibles from current sales, which is $2,800.

There are two roots of a quadratic equations always(assuming existence of complex numbers). We say that the considered quadratic equation has 2 solution if roots are distinct, and have 1 solutions when both roots are same.

For this case, the given equation is:

[tex]x^2 - x = -1/4[/tex]

Converting this to the form [tex]ax^2 + bx + c = 0[/tex], we get:

[tex]x^2 - x + 1/4= 0\\or\\4x^2 -4x + 1 = 0[/tex]

Thus, we get:

a = 4, b = -4, c = 1

Putting these values in the expression for discriminant, we get:

[tex]D = b^2 - 4ac =(-4)^2 - 4(4)(1) = 16 - 16 = 0[/tex]

The discriminant is 0, so the considered quadratic equation is going to have both roots real and equal. Or in terms of distinct solutions, it is going to have one real solution (distinct).

Answer:

[tex]\sqrt{28} \approx 5.3[/tex]

Step-by-step explanation:

The Pythagorean Theorem says if you have a right triangle, then relationship between the three sides is the sum of the square of each leg is the hypotenuse squared.

So [tex]a^2+b^2=c^2[/tex]

where a and b are legs and c is the hypotenuse.

Plug in your a,b, and c. In this case it is a,6, and 8.

This means we have

[tex]a^2+6^2=8^2[/tex]

Simplify where you can before we begin the solving (the moving around of things to other sides).

[tex]a^2+36=64[/tex]

Now time for the solving. We are first going to get [tex]a^2[/tex] by itself.

To do this, we just need to subtract 36 on both sides giving us:

[tex]a^2=64-36[/tex]

[tex]a^2=28[/tex]

Now to get rid of the square on a, just square root both sides:

Find the area of the base of the rectangular pyramid

The volume of the rectangular pyramid is equal to

[tex]V=\frac{1}{3}BH[/tex]

where

B is the area of the base and H is the height of the pyramid

we have

[tex]V=50\ units^{3}[/tex]

[tex]H=5\ units[/tex]

substitute and solve for B

[tex]50=\frac{1}{3}B(5)[/tex]

[tex]B=30\ units^{2}[/tex]

step 2

Find the volume of the rectangular prism with the same base area and height than the rectangular pyramid

The volume of the rectangular prism is equal to

[tex]V=BH[/tex]

where

B is the area of the base and H is the height of the pyramid

we have

[tex]B=30\ units^{2}[/tex]

[tex]H=5\ units[/tex]

substitute

[tex]V=(30)(5)=150\ units^{3}[/tex]

step 3

Compare the volumes

Volume of the rectangular pyramid -------> [tex]50\ units^{3}[/tex]

Volume of the rectangular prism -------> [tex]150\ units^{3}[/tex]

therefore

The volume of the rectangular prism is three times the volume of the rectangular pyramid

By looking at the graph, we can visually determine that the value of y when point x = -2 is -4.

Answer:

-4

Step-by-step explanation:

The y value at x=-2 is -4 because when you go to -2 on the x-axis the function is below there.  You can only go straight up or straight down to determine the y-value that corresponds to x=-2 so we go down because the function is below the x-axis there.

We are going to go down until we get on the graph of the line.  Scroll over with eyeballs to see that the y there is -4 (use the y-axis).

So the ordered pair (-2,-4) is on our line and when x=-2, y=-4.

P(x = 3) is unusual event

Step-by-step explanation:

Part A)

The probability distribution with correct formatting is shown in the table attached with:

We have to find the mean and standard deviation of this distribution. The mean of the probability distribution is calculated as summation of the products of "the variable with its respective probability".

[tex]u = \sum x P(x)[/tex]

So, for the given distribution:

Mean = 0(0.4096) + 1(0.4096)+2(0.1536)+3(0.0256)+4(0.0016)

Mean = 0.8

Standard deviation is calculated by the following formula:

[tex]\sigma=\sqrt{\sum x^{2}P(x) - u^{2}}[/tex]

[tex]x^{2}P(x)=1.28[/tex]

Substituting the values, we get:

[tex]\sigma=\sqrt{1.28-(0.8)^{2}}\\\\ \sigma=0.8[/tex]

Part B)

Answer:

t = 4.06 sec

Step-by-step explanation:

First of all, if the initial velocity is 64 feet per second, then the parabola should actually look like this:

[tex]h(t)=-16t^2+64t+4[/tex]

The initial velocity is in the place of our linear term, so it should be 64 not just 4.

Anyways, the h(t) value represents the height of the object after a certain number of seconds, t, it was launched from the initial height. We are looking for the length of time it takes the object to hit the ground.  The height of something on the ground is 0.  So we replace h(t) with a 0 and factor to solve for the values of t:

[tex]0=-16t^2+64t+4[/tex]

If you plug that into the quadratic formula to factor it, you will get that the values of t are

t = -.06 seconds and

t = 4.06 seconds

We all know that the 2 things in math that will never EVER be negative are time and distance/measures, so we can safely disregard the negative value of time.  

It takes the ball 4.06 seconds to hit the ground when it is launched from an initial height of 4 feet.

so the rainwater flows as R(x), and the decrease of the flow will be D(x), the new smaller pipe after the decrease will have water flowing at R(x) - D(x)

To find the rate of water flow through the smaller pipe, subtract the decrease function from the original rate function.

To find the rate at which rainwater flows through the smaller pipe, we need to subtract the decrease function from the original rate function. Let's call this new function H(x). So, H(x) = R(x) - D(x).

Substituting the given values, H(x) = (-0.1x^3 + 1.4x^2 - 1.5x) - (-0.04x^3 + 0.5x^2 + x). Simplifying, H(x) = -0.1x^3 + 1.4x^2 - 1.5x + 0.04x^3 - 0.5x^2 - x.

Combining like terms, H(x) = -0.06x^3 + 0.9x^2 - 2.5x.
