James will end up with his original t cars and half of (t+13) cars, so will have ...

... t + (t+13/2) = (3t +13)/2 . . . . cars James has after Paul's gift

To find out how many cars James will have after Paul gives him half of his cars, we need to determine the numbers of cars James and Paul have. We then calculate half of Paul's cars and add that to James' original number of cars.

To find out how many cars James will have after Paul gives him half of his cars, we need to first determine how many cars Paul has in total.

We know that Paul has 13 more cars than James, so we can set up an equation:

Paul's cars = James' cars + 13. Next, we need to find out how many cars Paul will give to James, which is half of Paul's cars.

We can set up another equation: cars Paul gives to James = Paul's cars ÷ 2.

Finally, to find out how many cars James will have after Paul gives him half of his cars, we simply add the number of cars Paul gives to James to James' original number of cars.

Let's say James has 5 toy cars. Paul has 13 more, so Paul has 5 + 13 = 18 toy cars.

Half of Paul's cars is 18 ÷ 2 = 9 toy cars. James will have 5 + 9 = 14 toy cars after Paul gives him half of his cars.

Answer:

1/3 of the time.

Step-by-step explanation:

This is because since the dice is being tossed 1 time, that would mean that there is only a 2 in 6 chance to roll a number under 3

The probability that the cube will show a number less than 3 is 1/3 and this can be determined by using the given data.

Given :

A number cube is labeled 1 to 6. the cube will be tossed once.

The following steps can be used in order to determine the probability that the cube will show a number less than 3:

Step 1 - According to the given data, a number cube is labeled 1 to 6. the cube will be tossed once.

Step 2 - So, the number under three is 1 or 2.

Step 3 - Therefore, the probability that the cube will show a number less than 3 is:

Answer:

radius = ((3*Volume) ./ ((2+M).*pi)).^(1/3);

surfaceArea = pi .* radius.^2 .* (2+sqrt(1+M.^2));

Step-by-step explanation:

The OP didn't include this part, but the original problem has the equations written for you in the header. Here they are again:

A = [tex]\pi R^{2}[/tex](2 + [tex]\sqrt{1+M^{2} }[/tex])

V = [tex]\pi R^{3} (2+M)/3[/tex]  where M = H/R

The problem is asking for the surface area of the balloon, but the only values that the user inputs are volume and M. We need to solve for the radius before we can complete the code. So, we can solve for R in one equation and plug it into the second equation.

Let's adapt the given equation V = [tex]\pi R^{3} (2+M)/3[/tex] and solve for R to get the equation for the radius.

V = [tex]\pi R^{3} (2+M)/3[/tex]

3*V = [tex]\pi R^{3} (2+M)[/tex]

[tex]\frac{3*V}{\pi (2+M)} = R^{3}[/tex]

R = [tex](\frac{3*V}{\pi (2+M)})^{1/3}[/tex]

Now, let's convert the equation for R to MATLAB code. Because we are using arrays, each operational symbol must be preceded by a "." unless it is a + or -.

R = [tex](\frac{3*V}{\pi (2+M)})^{1/3}[/tex]

radius = ((3*Volume) ./ ((2+M).*pi)).^(1/3);

Okay, so the hard part is done. The second line of code is easy: all you have to do is transform the given equation for surface area into MATLAB code while using the variable we named "radius" in the last step. Again, because we are performing operations with arrays, use "." in front of all operational symbols (except + and -).

A = [tex]\pi R^{2}[/tex](2 + [tex]\sqrt{1+M^{2} }[/tex])

surfaceArea = pi .* radius.^2 .* (2+sqrt(1+M.^2));

Putting it all together, your answer should be

radius = ((3*Volume) ./ ((2+M).*pi)).^(1/3);

surfaceArea = pi .* radius.^2 .* (2+sqrt(1+M.^2));

8x + 16 = 4x - 8 ( subtract 4x from both sides )

4x + 16 = - 8 ( subtract 16 from both sides )

4x = - 24 ( divide both sides by 4 )

x = [tex]\frac{-24}{4}[/tex] = - 6

Answer: ⇒ x=-6

_________________________________________________________

Step-by-step explanation:

Apply fraction cross multiply.

[tex](x+2)*8=(x-2)*4[/tex]

Expand.

[tex]8x+16=4x-8[/tex]

Subtract by 16 from both sides of equation.

[tex]8x+16-16=4x-8-16[/tex]

Simplify.

[tex]8x=4x-24[/tex]

Subtract by 4x from both sides of equation.

[tex]8x-4x=4x-24-4x[/tex]

Simplify.

[tex]4x=-24[/tex]

Divide by 4 from both sides of equation.

[tex]\frac{4x}{4}=\frac{-24}{4}[/tex]

Simplify it should be correct answer.

The equipment elevator descends to 176 feet below the surface while the miners' elevator descends to 210 feet below the surface after 14 seconds. Therefore, the miners' elevator is deeper.

To solve this, we first need to determine the position relative to the surface of both elevators in the gold mine. As the equipment elevator begins to descend first and moves at a speed of 4 feet per second, it had already traveled 30 (seconds) * 4 (feet per second) = 120 feet downward before the miners' elevator begins to descend.

Then, an additional 14 seconds pass. In these 14 seconds, the equipment elevator will descend a further 14 * 4 = 56 feet. Therefore, the equipment elevator is 120 + 56 = 176 feet below the surface.

The miners' elevator descends at 15 feet per second, and it has been moving for 14 seconds. Therefore, it is 15 * 14 = 210 feet below the surface. At this point in time, the miners' elevator is deeper than the equipment elevator by 210 - 176 = 34 feet.

The equipment elevator will be at a depth of 176 feet, while the miners' elevator will be deeper at a depth of 210 feet from the surface after the given time. The miners' elevator is deeper.

The position of each elevator relative to the surface after another 14 seconds can be found by first determining the distance each has traveled. The equipment elevator descends at 4 feet per second, and it had already been descending for 30 seconds before the miners' elevator started. Therefore, by the time the miners' elevator begins to descend, the equipment elevator will have descended 4 feet/second * 30 seconds = 120 feet.

From that point, after another 14 seconds, the equipment elevator descends an additional 4 feet/second * 14 seconds = 56 feet. Thus, its total descent is 120 feet + 56 feet = 176 feet from the surface.

On the other hand, once the miners' elevator starts, it descends at a rate of 15 feet per second. After 14 seconds, the miners' elevator will have descended 15 feet/second * 14 seconds = 210 feet.

Comparing both distances, the elevator for the miners is at 210 feet while the equipment elevator is at 176 feet from the surface. So, the miners' elevator is deeper.

substitute x = 350 into the equation for y

y = [tex]\frac{104000}{350}[/tex] + 235 ≈ 532 000

Final answer:

To find the size of the oil tanker that can be built for $350 per ton, solve the equation 350 = 104,000/x + 235 for x, yielding approximately 904 thousand tons. None of the multiple-choice options match this result.

Explanation:

The student is asked to calculate the size of an oil tanker that can be built for $350 per ton using the given model for cost per ton, which is y = 104,000/x + 235, where y is the cost in dollars per ton, and x is the tons in thousands. To find x, set the equation equal to 350 and solve for x.

350 = 104,000/x + 235

Subtract 235 from both sides to get:

350 - 235 = 104,000/x

115 = 104,000/x

To solve for x, multiply both sides by x and then divide both sides by 115:

x = 104,000 / 115

x ≈ 904.35

Since x is in thousands of tons, the size of the oil tanker that can be built for $350 per ton is approximately 904 thousand tons. However, this answer does not match any of the options provided in the multiple choice (a. 62 thousand tons, b. 6 thousand tons, c. 532 thousand tons, d. 178 thousand tons), suggesting there might be an error in the question or the offered choices.

Given expression is

-33/-10- (-45.3+ 35.2)

Problem says that it is simplified.

After simplification it gives:

-33/-10+?

Now we need to find the unknown value that goes in place of ?.

Notice that it is expression having only constants so we will get a unique answer not the smallest or largest value.

Now let's find the value of unknown that goes in place of ?

-33/-10- (-45.3+ 35.2)= -33/-10+?

we see that -33/-10 is on both sides so we can remove that

- (-45.3+ 35.2)= ?

Now let's simplify the left side by distributing the negative sign

+45.3 - 35.2= ?

10.1 = ?

Hence the unknown value is 10.1 that goes in place of ?.

Step by step explanation:

We have to determine the answer among all the options.

Option A: [tex]\left( {x - 4} \right)[/tex] is a factor of [tex]3{x^2} - 13x + 4[/tex].

It can be observed from the given synthetic division the polynomial is [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] that is divisible by the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Therefore, the polynomial [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] is a factor of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Therefore, the option A is correct option.

Option B: [tex]\left( {x + 4} \right)[/tex] is a factor of [tex]3{x^2} - 13x + 4[/tex].

From the option A, it has been proved that [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] is a factor of the polynomial  

[tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex]

Therefore, [tex](x+4)[/tex] is a not factor of [tex]3{x^2} - 13x + 4[/tex].

Thus, the option B is not correct option.

Option C: The number [tex]-4[/tex] is a root of  [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

From the option A, it has been proved that [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] is a factor of the polynomial  

[tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex]

Now substitute 0 for [tex]g\left( x \right)[/tex] in the equation [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] to find the root of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex] as,

[tex]\begin{aligned}0&= \left( {x - 4} \right) \hfill\\x&= 4 \hfill\\\end{aligned}[/tex]  

It can be seen that the value of [tex]x[/tex] is 4 it means [tex]-4[/tex] is not a root of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Therefore, the option C is not correct option.

Option D: The number [tex]4[/tex] is a root of [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

It can be seen that the value of [tex]x[/tex] is 4 in option C it means [tex]4[/tex] is a root of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Therefore, the option D is correct option.

Option E: [tex]\left( {3{x^2} - 13x + 4} \right) \div \left( {x - 4} \right) = \left( {3x - 1} \right)[/tex]  

The option E is also correct as [tex](x-4)[/tex] is the factor of the polynomial  [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Option F: [tex]\left( {3{x^2} - 13x + 4} \right) \div \left( {x + 4} \right) = \left( {3x - 1} \right)[/tex]  

The option F is not correct as [tex]\left( {x + 4} \right)[/tex] is not the factor of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Result:  

Therefore, the correct options are [tex]\boxed{{\mathbf{Option A, D and E}}}[/tex].

Polynomial function of grade 5

Given roots: -2, 2,[tex]4 + i[/tex]

Having an imaginary root given by [tex]a + bi[/tex], the other root, in the same imaginary way, must be given by its complex conjugate, that is, [tex]a-bi[/tex].

In this way, the fourth root is given by:

[tex]4-i[/tex]

Since the polynomial function is grade 5, it must have 5 roots. Thus, the fifth root must be given by a real number.

Thus, the roots of the polynomial function are given by: three real roots and two imaginary roots.

Answer:
