Can someone help me solve this integral plsss?


integral of (2xˆ3+3xˆ2+x)/(xˆ2+1) dx

Answer:

Step-by-step explanation:

- 4x^3 / (- 4) = 32 / (- 4)

x should and cannot be negative or it shouldn't be for example (- x) = 90

cubic root (x^3) = cubic root (- 8)

x = cubic root (- 8)

x = 2i

what is "i"?

It is an imaginary number as you cannot square, cubic, or whatever root with a negative in it. so instead you must add "i" to remove the negative as a replacement and indicator that it was a negative number.

sin(x) = 1/2 and the angles must be between 0 and 180.

We can take the arcsin(1/2) and we get 30 degrees, but that is only half of the answer.

There are two angles for which the y value on the unit circle outputs 1/2.

To find this other value which is in the second quadrant: 180 - 30 = 150.

The other angle is 150 and can be checked by solving sin(150) which outputs 1/2 so we know have the correct answer.

Smaller =  30   Larger = 150.

P.S make sure your calculator is in degree mode.

Answer:

116 in

Step-by-step explanation:

Answer:

Step-by-step explanation:

Recall that distance = (rate)(time).  Here the rate is 30 mph and the time 3.5 hr.  The distance traveled is proportional to the time passing by.  The graph of the distance function is a straight line with slope equal to the "rate" named above:

d(x) = (30 mph)x

Since x (elapsed time) can't be negative in this situation, we write the domain as 0 ≤ x ≤ 3.5 hr.

Answer:

-29 13/35

Step-by-step explanation:

Answer:

That distance is 6.4

Step-by-step explanation:

The legs of the triangle form a right angle.  The bottom leg has length 8 - 3, or 5, and the vertical leg -3 - (-7), or 4.  Applying the Pythagorean Theorem:

(vertical leg)^2 + (horizontal leg)^2 = (hypotenuse)^2, which here is

4^2 + 5^2 = (hypotenuse)^2

This works out to 16 + 25, or 41.

The distance between these two points is d = √41, or d = 6.4

Answer:

Step-by-step explanation:

Speed and time are inverse functions.

At normal speed the time is 10 hours.

If the speed is 2.5 times faster, then time is 2.5 times less:

Speed is 2.5

Distance is 10

Step-by-step explanation:

Order of congruence does not matter. For any angles A,B, and C , if ∠A≅∠B and ∠B≅∠C , then ∠A≅∠C . If two angles are both congruent to a third angle, then the first two angles are also congruent.

Answer:

True

Step-by-step explanation:

Answer:

91°

Step-by-step explanation:

The answer is 91°. What you do is you name the angle next to 89° with x, and you know that an angle whose arms are horizontal makes 180°. So, you go:

180°=x+89°

x=180°-89°

x=91°.

Now, there is this rule that says that when two angles are on sides like x and ? are, then they are equal. Therefore, the angle marked with ? is 91°.

Answer:

Below.

Step-by-step explanation:

1. Divide both sides by 2.

2. After dividing both sides by we would have:

x + 14 = 20

The next step would be

Subtract 14 from both sides.

3. 2(x + 14) = 40

x + 14 = 20

x = 20 - 14

x = 6.

2x + 28 = 40

2x = 40 - 28

2x = 12

x = 6.

The answer is communitive property.

Step-by-step explanation:

The Empirical Rule states that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean. Under this rule, 68% of the data falls within one standard deviation, 95% percent within two standard deviations, and 99.7% within three standard deviations from the mean.

Answer:

4

Step-by-step explanation:

We start with this:

[tex]\frac{5x-6y +20z}{4yz}[/tex]

Then we insert the vales of the variables like this:

[tex]\frac{5(5)-6(3) +20(\frac{1}{4} )}{4(3)(\frac{1}{4}) }[/tex]

Next, Simplify:

[tex]\frac{25-18 +5}{3 }[/tex]

[tex]\frac{12}{3 }[/tex]

Simplify further, and we get our answer: 4

Answer:

Step-by-step explanation:

if the diagonal of a square is 11.3 what is the perimeter

from the diagonal we find the area, which can also be found by multiplying diagonal by diagonal divided by two, then we make the square root of the area and find the side, we multiply by four and we have the perimeter

(11.3 * 11.3) : 2 = 63.8 u² (Area)

√63.8 = 7.9 (side)

7.9 * 4 = 31.6u (perimeter)

Answer:

7! = 5040

Step-by-step explanation:

7! is a factorial expression that can be solved as follows:

7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040

Therefore, 7! = 5040

Answer:

Karl is 16 and Danny is 12

Step-by-step explanation:

Answer:

8 ft. 5 in.

Step-by-step explanation:

First, let's change everything to inches

[] 3 ft. 8 in -> 3 * 12 = 36, 36 + 8 = 44 inches

[] 4 ft. 9 in -> 4 * 12 = 48, 48 + 9 = 57 inches

Now, we can add

44 + 57 = 101 inches

Last, we will simplify

101 -> 8 feet and 5 inches
