The college bookstore paid $44.4 for the book

A college store marks up the price it pays the publisher for a book by 35%

The selling price of the book is $60.00

Therefore the amount paid by the bookstore can be calculated as follows

( 35/100 + 1) x = 60

0.35+1x= 60

1.35x= 60

Divide both sides by the coefficient of x which is 1.35

The value of x in the equation x² - 2 x + 5 = 2 is 1 ± i √2.

We are given the equation:

x² - 2 x + 5 = 2

We need to solve the equation to find the value of x.

For this, we will first subtract 2 from both the sides:

x² - 2 x + 5 - 2 = 2 - 2

x² - 2 x + 3 = 0

Now, we will solve for the value of x:

D = b² - 4 ac

D = (- 2)² - 4 (3)(1)

D = 4 - 12

D = - 8

√D = 2 i √2

Now putting it in quadratic formula, we get that:

x = (- b ± √D) / 2 a

x = (2 ± 2 i √2) / 2 (1)

x = 1 ± i √2

Therefore, the value of x in the equation x² - 2 x + 5 = 2 is 1 ± i √2.

3. Your friend is incorrect. A dozen DVD's is gotten for $84.

4. 50 DVD's from the website would cost: $312.

The y-intercept is the value of the y-coordinate of the point where the line intercepts the y-axis.

The y-intercept is referred to as the starting value or initial value. At this point, x = 0.

1. First, find the slope (m) of the line using two points, (1, 18) and (2, 24):

Slope (m) = change in y/change in x = (24 - 18)/(2 - 1) = 6/1

Slope (m) = 6

Substitute m = 6 and (x, y) = (1, 18) into y = mx + b to find the y-intercept, b:

18 = 6(1) + b

18 - 6 = b

b = 12 (y-intercept)

Substitute m = 6 and b = 12 into y = mx + b:

y = 6x + 12

The y-intercept that connects all the data points is: 12.

2. The y-intercept in this context represents the initial cost that excludes the charge for each DVD.

3. Substitute x = 12 into y = 6x + 12 and solve to see if y equals 90:

y = 6(12) + 12

y = 84 [not equal to $90)]

After pumping all of container A into container B there will remain empty space in B = 78.5 ft³

The percentage for this empty space is of the entire volume is = 3.4 %

What is volume of cylinder?

Volume of cylinder is calculated as;

v = π r² h  

Since, Container A has a diameter of 18 feet and a height of 9 feet.

Then, Radius = 18/2 = 9 ft

Hence, Volume of Container A = π r² h  

                                                = 3.1416 * 9 * 9 * 9

                                                = 2,290.22 ft³

Since,  Container B has a diameter of 16 feet and a height of 11 feet.

Then, Radius = 16/2 = 8 ft

Hence, Volume of Container B = π r² h

                                               = 3.1416 * 8 * 8 * 11

                                               = 2,211.68 ft³

After pumping all of container A into container B there will remain empty space in B = 2,290.22 - 2,211.68 = 78.5 ft³

And, The percentage for this empty space is of the entire volume is,

78.5/2,290.22 = 0.03427 *100 = 3.4 %

So, we have

6x ≤ 18 or 1/3x > 6

Divide both sides of the compound inequality by the coefficient of x

So, we have

x ≤ 3 or x > 18

A transformation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).

Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.

It should be noted that in order to measure the value, the measurement has to be in the same unit.

The fundamental idea in the study of science and mathematics is measurement. The qualities of an object or event can be quantified so that we can compare them to those of other objects or occurrences. When discussing the division of a quantity, measurement is the word that is used the most frequently.

Measurement is crucial in establishing connections across different branches of mathematics. For instance, it gives the use of math abilities and spatial concepts a rich and meaningful context. Measurement also establishes connections between mathematics and other academic disciplines.

From the information, it was illustrated that the boys all had measurements of trees taken. Therefore, it should be noted that since they are in different units, it cannot be done.

In this case, the reason is that in order to measure the value, the measurement has to be in the same unit. This will make it easier to do the calculation.

ez

have a good day

Step-by-step explanation:

so, if I understand you correctly and nothing was left out :

f(t) = t² + 8t + 9

d(t) = t² + 11t + 4

just by looking at the 2 functions, it is clear that d(t) creates larger functional values for higher values of t.

because t² = t², but 11t > 8t. and the constants in the end are irrelevant for larger numbers.

so the pool will drain.

a.

w(t) = f(t) - d(t) = t² + 8t + 9 - t² - 11t - 4 = -3t + 5

b.

yes, it will completely drain, as -3t will drive it to 0, and if it was physically possible into the negative ask the way to -infinity.

c.

-3t + 5 = 0

5 = 3t

t = 5/3

it will be completely drained after

1 2/3 hours = 1 hour 40 minutes.

d.

to intersect they need to create the same result for a value of t :

t² + 8t + 9 = t² + 11t + 4

8t + 9 = 11t + 4

-3t + 5 = 0

t = 5/3 or 1 hour 40 minutes.

that means that the filling and the draining are only equal, when there is no water in the pool.

that also means that f(t) is actually calculating how much water there is in the pool, if there would not be no drain, with a starting value of 9.

e.

the domain is the interval or set of all valid input values (here for t).

negative t (hours) don't make any sense for any of the 3 functions.

but f(t) can go on theoretically forever. but usually it's limited by the size of the pool (once it reaches the top, there is no more filling). we just don't know anything about that.

so, the domain for f(t) is

0 <= t < +infinity

d(t) could go on and on as well, as long as there is water in the pool.

so, the domain for d(t) is also

0 <= t < +infinity

but w(t) based on its meaning and definition makes only sense between the start (t = 0) and until the water is fully drained by the combination of f(t) and d(t).

so, the domain of w(t) is

0 <= t <= 5/3

we could define w(t) as segmented function

w(t) = -3t + 5 0 <= t <= 5/3

= 0 t > 5/3

THEN the domain would be again

0 <= t < +infinity

The probability that the sample contains 2 female voters is 0.31104

Binomial distribution uses two values; n and p. n represent the counts of sample that are being collected. On the other hand, p represents the chances of being successful on any trial. Using the two values, the probabilities are computed for binomial distribution.

Probability that a random voter is female is 0.40(p).

Sampled voters are 6(n).

Let X be the number of females in the sampled voters.

Then,

X∼ Bin (n, p)

∼Bin (6,0.4)

Probability that the sample contains exactly 2 female voters is,

P (X =2) = 6C2 (0.4)2 (1−0.4)6−2
