Evaluate the integral. (Assume a ≠ b. Remember to use absolute values where appropriate. Use C for the constant of integration.)

Bess [88]

Answer:

<u><em>F(x)= 5*[ $\frac{x^{3} }{3}$ + (a*b)* $\frac{x^{2} }{2}$ + a*b*x + C.</em></u>

Step-by-step explanation:

<u><em>First step we aplicate distributive property to the function.</em></u>

<u><em>5*(x+a)*(x+b)= 5*[ $x^{2}$ +x*b+a*x+a*b]</em></u>

<u><em>5*[ $x^{2}$ +x*(b+a)+a*b]= f(x), where a, b are constant and a≠b</em></u>

<u><em>integrating we find ⇒∫f(x)*dx= F(x) + C, where C= integration´s constant</em></u>

<u><em>∫^5*[ $x^{2}$ +x*(a+b)+a*b]*dx, apply integral´s property</em></u>

<u><em>5*[∫ $x^{2}$ dx+∫(a*b)*x*dx + ∫a*b*dx], resolving the integrals </em></u>

<u><em>5*[ $\frac{x^{3} }{3}$ + (a*b)* $\frac{x^{2} }{2}$ + a*b*x</em></u>

<u><em>Finally we can write the function F(x)</em></u>

<u><em>F(x)= 5*[ $\frac{x^{3} }{3}$ + (a*b)* $\frac{x^{2} }{2}$ + a*b*x ]+ C.</em></u>

If a is a positive integer and b is a negative integer, which expression must be positive?

nydimaria [60]

So, let's solve all of them and see:

a - (-b) = a + b ⇒ can be either positive or negative, depending on the numbers

a + (-b) = a - b ⇒ can either be positive or negative, depending on the numbers

a * (-b) = a * (-b) ⇒ negative answer no matter what

a / (-b) = a / (-b) ⇒ negative answer no matter what

So the answer is:

<em>"None of the above"</em>.

If a roll of vinyl costs 37$ and is a total of 210 sq in how much is each square inch and how to I figure that out?

fenix001 [56]

Answer:

0.176 $

Step-by-step explanation:

Write a proportion.

37 dollars is to 210 square inches as x dollars is to 1 square inch.

37 $ / 210 in² = x / 1 in²

x ≈ 0.176 $

A jet travels 590 miles in 5 hours; how far can it travel in 11 hours. With an explanation.

White raven [17]

First divide 590 by 5 which equals 118
then take 118 and multiply by 11 which equals 1298 miles. the jet will be able to travel 1298 miles in 11 hours

A teacher dropped 8 coins on the table and counted the number of tails to simulate the number of questions a student might guess

Tomtit [17]

Answer:

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)

Step-by-step explanation:

This is a problem of empirical probability calculation, since the teacher tries to find by means of the experimental method, the number of correct answers that a student could correctly guess in a true / false test with 8 questions.

If the teacher throws the 8 coins and then counts the number of tails, the graph shows the frequency with which 1, 2, 3, 4, 5, 6, 7 and 8 tails are obtained in the 100 attempts.

Therefore, the least probable result was the one that was obtained less frequently in the experiment or, in other words, the one that contains fewer points in the diagram, which in this case are:

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)
