Answer:

1. 11x + C

4. 5/14 x^2 + C

Step-by-step explanation:

When taking an integral of a one term power function, which means it has one number multiplied by an x t some power, so ax^b you use the power rule for integration.  

ax^b becomes \frac{ax^{b+1}}{b+1}

So first you identify a and b and just plug in.  I will walk you through all of them through the comments if you like, but here I am just going to solve one.  Inf act I'll solve one that looks the hardest.  

Number 4.  We have (5/7)x.  so a is 5/7 and b is 1.  so just fill in.

\frac{\frac{5}{7}x^{1+1} }{1+1}\\\frac{\frac{5}{7}x^{2} }{2}

From here you can actually divide 5/7 by 2 and get 5/14 so the answer is 5/14 x^2 + c.  Since these are indefinite integrals NEVER forget the constant C.  Go ahead and try taking tis derivative though.  Just remember C is a constant.

Also I wanted to mention, if you just have a number, so in number 1 it's ust 11, it is the same as 11x^0 so b is 0 in this case.  So bonus, the answer to 11 is 11x + C.  Never forget the C.

Let me know if there are any specifically you need help with, or you do want to work through all of them.

Answer:

y=3/5X+5/6

Step-by-step explanation:

Y=ax+b

(-4;-3)  (6:3)

-3=-4a+b

3=6a+b

3-6a=-3+4a

6=10a

a=6/10=3/5

b=5/6

Gwen volunteered to work at the ticket booth for her school's Halloween carnival. The chart below gives the number of hours Gwen
n200080 [17]

A linear relation is a relationship between two variables that when the corresponding pair of values of the variables are plotted, a straight line is obtained

The equation for the relationship between hours Gwen worked and number of tickets is <u> t = </u><u>15·h</u>

<u />

The reason the above equation is correct is as follows:

The given parameters are;

The table of values;

Hours(h): 1, 2, 3, 4

Tickets (t): 15, 30, 45, 60

Required: To write an equation that gives the relation between the number of hours Gwen worked and the number of tickets sold

Solution:

From the given table, we have;

The common difference between successive <em>h-values </em>is 1

The <em>common difference</em> between successive t<em>-values </em>is 30 - 15 = 45 - 30 = 60 - 45 = 15 = Constant

Given that the common difference of the <em>h</em>, and <em>t-values</em> are constant, the relationship is a linear relationship of the form, t = m·h + c

Where;

m = The rate of change of <em>t</em> with <em>h</em>, as follows;

m = (30 - 15)/(2 - 1) = 15

∴ t - 15 = 15 × (h - 1)

t - 15 = 15·h - 15

t = 15·h - 15 + 15 = 15·h

t = 15·h

The equation for the relation between the number of hours Gwen worked and the number of tickets she sold is<u> t = </u><u>15·h</u>

<u />

A Game of Thrones fan predicts there is a 70% chance that her favorite character will survive the next season and a 75% chance t
zepelin [54]

Answer:

  • <em>The probability that the second favorite character will die given that the first favorite character dies is</em><u> 0.53</u>

  • <u>This kind of probability is called conditional probability</u>

Explanation:

Name the events and their probabiities:

  • Event  A: her favorite character will survive, so P (A) = 0.70

  • Event B: her her second favorite character will die, so P(B) = 0.75

  • Both characters will die ⇒ P (B and not A) = 0.16

You want to find P (B | not A).

That is the probability of the succes B (the second favorite character will die) given other event (not A or the first favorite character dies) is certain (it happens) and that is called conditional probability.

  • P (not A) is the complement probability of A, so P (not A) = 1 - P(A) = 1 - 0.7 = 0.3

So, you have P(B), P(not A) and want to find P (B | not A)

The definition of conditional probability is:

  • P (X | Y) = P (X and Y) / P (Y)

So, replacing with our terms, we get:

  • P ( B | not A) = P (B and not A) / P (not A) = 0.16 / 0.3 ≈ 0.53
