a cylindrical oil pipe measures 4 feet in diameter and 251.2 cubic feet in volume. what is the height of the oil pipe?
​

Here you go! I apologize if it makes no sense. I write my notes and practice problems super weirdly.

Answer:

2(k+1)(k+2)(k+5)

29.

[tex]f(x) = -x^2-7x-6[/tex]

As [tex]x \to \pm \infty[/tex], [tex]y \to - \infty[/tex].

This can be easily verified by looking at the graph (graph of a quadratic equation).

30.

The growth of a population is not linear, it's exponential.

31.

Exponential growth > polynomial, so [tex]y = 3^x[/tex].

35.

[tex]V(t) = 30\cdot (25)^{\frac{t}{20}}[/tex]

The question is asking V(t) for t = 40.

[tex]V(40) = 30\cdot (25)^{\frac{40}{20}} \\~\\V(40) = 30\cdot 25^2 \\~\\V(40) = 30\cdot 625 \\~\\V(40) = 18750[/tex]

36.

The point of symmetry of a quadratic equation [tex]y = ax^2+bx+c[/tex] is at its vertice:

[tex]V_x = \dfrac{-b}{2a}[/tex]

[tex]V_x = \dfrac{6}{2}[/tex]

[tex]V_x = 3[/tex]

The line is x= 3.

Answer: 3/50

Step-by-step explanation: add up 117 + 24 + 9 = 150

Then do 9 (the number of people who purchased more than one art work) (written as a fraction) over 150

Then simplify 9/150 to 3/50

Answer:

30(0.5b+3.75)

Step-by-step explanation:

if b is beads and 0.50 is the price of a bead, you have to multiply the two together. The beads and 3.75 go together bc that's all for 1 necklace. The 30 multiplies all of them bc it's 30 necklaces

Answer:

B)

Step-by-step explanation:

y-intercept = -2

slope = 1

in slope-intercept form the line would be:  y = x - 2

if we subtract 'x' from each side we get:

-x + y = -2

we don't want to leave 'x' as negative so we can multiply each term by -1 to get:

x - y = 2

Answer:

x = 150°

Step-by-step explanation:

t1 and t2 are parallel lines, so the line going across them have identical angles. Since 150° is already given on the section that crosses t1, we can assume the same value for t2.

Answer:

So If you start with sinØ = .5

your calculator is programmed to always give the closest angle to 0, and that would be 30°

You probably used the cosine law to find the first angle. A suggestion is to always find the largest angle first. If that happens to be an obtuse angle, your calculator will find the correct angle.

Of course there can only be one obtuse angle in a triangle, so using the sine law for your second angle does not result in any problems

notice that in your solution 78 and 102 add up to 180 , and sin 78 = sin(180-78) = sin 102

I would have found angle S first, the largest angle always opposite the largest side.

7^2 = 5^2 + 4^2 - 2(5)(4)cosØ

40cosØ = -8

cosØ = -8/40 = -1/5

Ø = 101.537°

Now you can use the sine law and you will find the correct other angles.

Answer:

2

Step-by-step explanation:

First off, the slope of f(x) is -4.  It is in the form y=mx+b and m=-4.

For g(x), the slope can be calculated from any two points given.  I willuse (1,9) and (3,21) because I like positive numbers.  So, slope is rise over run and it is calculated from (y1-y0)/(x1-x0)  This gives me (21-9)/(3-1) which is equal to 6.  So adding the two slopes: 6+ (-4)=2

Step-by-step explanation:

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

[tex]\frac{1}{2} \times 100 = 50[/tex]

Add both skateboarding and walking

[tex]30\% + 50\%\\\\= 30 + 50\\\\= 80[/tex]

Now, subtract that from a whole percent

[tex]100 - 80 = 20\\\\20\%[/tex]

Convert it to a decimal

[tex]20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2[/tex]

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.

Answer:

6 / 23

Step-by-step explanation:

The question is not correct, the correct question is:

Leila is at a charity fundraiser and has a chance of receiving a gift. The odds in favor of receiving a gift are 6:17. Find the probability of Leila receiving a gift.

Solution:

Odds provide a measure of the likelihood of a particular outcome occurring. Odds is the ratio of the number of events that produce that outcome to the number that do not.

The probability of an event occurring is the ratio of number of favorable outcomes to the total number of outcomes possible.

Given that the odds in favor of receiving a gift are 6:17. Therefore:

number of favorable outcome = 6, number of unfavorable outcome = 17

Total number of possible outcomes = 6 + 17 = 23

The probability of Leila receiving a gift = number of favorable outcome / Total number of possible outcomes  = 6 / 23

The probability of Leila receiving a gift = 6 / 23
