Answer:

  B.  -1, 2, -4, 8

Step-by-step explanation:

The characteristic of a geometric sequence is that adjacent terms have a common ratio. Sequence B is the only one.

  2/-1 = -4/2 = 8/-4 = the common ratio: -2

___

Ratios of adjacent terms are different for the other sequences.

The [tex]z[/tex]-score for a height of 16.4 feet is

[tex]P(\text{height}>16.4\,\mathrm{ft})=P(Z>1.023)=1-F_Z(1.023)\approx0.153[/tex]

where [tex]F_Z(z)=P(Z\le z)[/tex] is the cumulative distribution function for the standard normal distribution.

Answer:

The correct answer is 3/4

Step-by-step explanation:

This is because if we first change them to using the same unit of measure we get the following.

3 ft/48 in

36 in/48 in

Now we can simplify by dividing both by 12

3/4

(-9,11) This one is eleven units from the y-axis

(10,15) is fifteen units away

(5,-12) is 12 units away

(-4,14) is 14 units away

so the one closest to the y-axis is (-9,11)

Please mark me as brainliest

The above answer is wrong. Once graphing the lines you will see the -4 and 14 is the closet to the y axis

I see no actual question, but I'm assuming that you want to find the dimensions of the rectangle.

In general, the area of a rectangle with width [tex]w[/tex] and length[tex]l[/tex] is

[tex] A = wl [/tex]

In this case, we know that the width is one-fourth of its length, which means [tex] w = \frac{1}{4}l[/tex]

If we plug this expression for w in the formula for the area, we get

[tex] A = wl = \dfrac{1}{4}l\cdot l = \dfrac{1}{4}l^2 [/tex]

We also know that the area is 9 squared units, so we have

[tex] 9 = \dfrac{1}{4}l^2 [/tex]

If we multiply both sides by 4, we get

[tex] l^2 = 36 [/tex]

Consider the square root of both sides (we only accept the positive solution, since a negative length would make no sense:

[tex] l = \sqrt{36} = 6 [/tex]

So, the length is 6, and the width is one-fourth of 6, i.e.

[tex]\dfrac{1}{4} \cdot 6 = \dfrac{6}{4} = \dfrac{3}{2} = 1.5[/tex]

Answer:

Both plans last for 1.25 hours (1 hour 15 minutes)

Step-by-step explanation:

Let x hours be the time needed for plan A and y hours be the time needed for plan B.

On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. Thus, 5x+3y=10.

On Thursday there were 2 clients who did Plan A and 6 who did Plan B. Thus, 2x+6y=10.

Solve the sytem of two equation. Multiply the first equation by 2, the second by 5 and subtract them:

[tex]10x+6y-10x-30y=20-50,\\ \\-24y=-30,\\ \\y=\dfrac{30}{24}=\dfrac{5}{4}=1.25\ hours.[/tex]

Therefore,

Answer:

A. lim [x ⇒ -∞] g(x) = -5 . . . . . . written in text form, not typeset

Step-by-step explanation:

A horizontal asymptote is a line that the function approaches but never reaches. It represents the limiting value that the function can have. (The function can come as close to that value as you like for some value of x, but can never actually reach that value.)

Here, you're told the asymptote for negative x values is -5. That means g(x) gets closer and closer to -5 for values of x that are more and more negative. That is, as x approaches infinity, g(x) approaches -5. We say -5 is the limit of g(x) as x approaches negative infinity.

___

The attached graph shows a function that has characteristics like those of g(x).

Answer:

Step-by-step explanation:

After you've worked a couple of "optimum cylinder" problems, you find that the cylinder with the least surface area for a given volume has a height that is equal to its diameter. So, the volume equation becomes ...

  V = πr²·h = 2πr³ = 39 in³

Then the radius is ...

  r = ∛(39/(2π)) in ≈ 1.83779 in ≈ 1.84 in

  h = 2r = 3.67557 in ≈ 3.68 in

_____

The total surface area of a cylinder is ...

  S = 2πr² + 2πrh

For a given volume, V, this becomes ...

  S = 2π(r² +r·(V/(πr²))) = 2πr² +2V/r

The derivative of this with respect to r is ...

  S' = 4πr -2V/r²

Setting this to zero and multiplying by r²/2 gives ...

  0 = 2πr³ -V

  r = ∛(V/(2π)) . . . . . . . . looks a lot like the expression above for r

__

If we substitute the equation for V into the equation just above this last one, we have ...

  0 = 2πr³ - πr²·h

Dividing by πr² gives ...

  0 = 2r - h

  h = 2r . . . . . generic solution for cylinder optimization problems

Answer:

3) 2/3

4) an = 162·(1/3)^(n-1)

Step-by-step explanation:

3) A geometric sequence has a common ratio between adjacent terms. Here, that ratio is ...

r = 54/162 = 18/54 = 6/18 = 1/3

Then the next two terms can be found by multiplying by the common ratio:

6 · 1/3 = 2

2 · 1/3 = 2/3 . . . . . the sixth term

____

4) The generic expression for the n-th term of a geometric sequence with first term a1 and common ratio r is ...

an = a1·r^(n-1)

We can put in the numbers for a1 and r, and we have ...

an = 162·(1/3)^(n-1)

Answer:

The correct answer options are (B) {(-6, 6), (-6, 7), (10, 12)} and (D) {(-6, 4), (10, 5)}.

Step-by-step explanation:

Here, we are given the domain {-6, 10} and we are to determine which of given relations in the options has this domain.

Domain is the set made up of the first elements of each ordered pair (x, y).

For {-6, 10} to be the domain, we will check which of the options have ordered pairs that start with -6 and 10.

If we look at option (B) {(-6, 6), (-6, 7), (10, 12)} and D. {(-6, 4), (10, 5)}, the first (two) ordered pair(s) start with -6 while the last ordered pair starts with 10.

Therefore, B and D are the correct answer option.

Answer:

B) 11:35 a.m.

Final answer:

The bottle will be half full at 11:50 PM, which is ten minutes before it is completely full at midnight, due to the exponential growth doubling the contents every ten minutes.

Explanation:

The question involves understanding exponential growth, specifically the doubling time of a population or, in a more tangible sense, the filling of a jar (or bottle). Given that a bottle doubles the amount inside every ten minutes and is full at midnight, we can calculate when the bottle will be half full by working backwards from the endpoint.

If the bottle is full at midnight, then it was half full at 11:50 PM, since the contents double every ten minutes. This reveals a common misunderstanding in our intuition about exponential growth, where significant change occurs in the final moments before reaching capacity.

In summary, to find out when the bottle will be half full, simply subtract a single doubling interval (ten minutes) from the time when the bottle is known to be full.

Answer:

First account (simple interest)

Step-by-step explanation:

The amount of interest earned by the first account is ...

I = Prt = $2000·0.04·7 = $2000·0.28 = $560

The amount in the second account at the end of 7 year is ...

FV = P·(1+r)^t = $2000·1.02^7 = $2297.37

so you have earned $297.37 in interest on the second account.

$560 is more than $297, so the First Account (simple interest) earns more money.

The percent that Container A is full after pumping its water into Container B until it is full is that Container A is 49.1% full after pumping water to Container B.

The problem asks us to determine what percent of Container A is full after Container B is full when water is transferred from Container A to Container B. We start by calculating the volume of both cylinders. The volume of a cylinder is given by the formula V = π r² h where V is volume, r is radius, and h is height.

Container A has a radius of 13 feet and a height of 13 feet, so:

π r² h ≈ 6985.3 cubic feet

Container B has a radius of 9 feet and a height of 14 feet, so:

π r² h≈ 3553.0 cubic feet

After filling Container B completely, the volume of water left in Container A is the original volume of Container A minus the volume of Container B. Therefore, the remaining volume in Container A is (6985.3 - 3553.0) cubic feet ≈ 3432.3 cubic feet.

To find the percentage full, we divide this remaining volume by the total volume of Container A and multiply by 100:

Percentage = (3432.3 / 6985.3) * 100 ≈ 49.1%.

After the pumping is complete, Container A is 48.4% full.

Calculate the volume of each container

The volume  of a cylinder is given by the formula:

[tex]\[V = \pi r^2 h\][/tex]

Volume of Container A

- Radius [tex]\( r_A = 13 \)[/tex]feet

- Height [tex]\( h_A = 13 \)[/tex] feet

[tex]\[V_A = \pi (13)^2 (13) = \pi (169)(13) = 2197\pi \text{ cubic feet}\][/tex]

Volume of Container B

- Radius [tex]\( r_B = 9 \)[/tex]feet

- Height [tex]\( h_B = 14 \)[/tex] feet

[tex]\[V_B = \pi (9)^2 (14) = \pi (81)(14) = 1134\pi \text{ cubic feet}\][/tex]

Calculate the remaining volume of water in Container A

Since Container A is initially full and the water is pumped into Container B until Container B is full, the remaining volume of water in Container A is:

[tex]\[V_{\text{remaining}} = V_A - V_B = 2197\pi - 1134\pi = (2197 - 1134)\pi = 1063\pi \text{ cubic feet}\][/tex]

Calculate the percent of Container A that is still full

The percent of Container A that is full is given by:

[tex]\[\text{Percent full} = \left( \frac{V_{\text{remaining}}}{V_A} \right) \times 100\%\][/tex]

Substituting the volumes we calculated:

[tex]\[\text{Percent full} = \left( \frac{1063\pi}{2197\pi} \right) \times 100\% = \left( \frac{1063}{2197} \right) \times 100\%\][/tex]

Simplifying the fraction:

[tex]\[\text{Percent full} = 0.484 \times 100\% = 48.4\%\][/tex]

Mason wins after 18 total moves

Step-by-step explanation:

Mason's optimal strategy is to keep the total number of marbles at 11n+1, so he will take 10 marbles to start. For each move Jason makes, Mason will take a number of marbles that makes the sum from the two turns be 11.

After each of Mason's 9 turns, the number of remaining marbles will be ...

89, 78, 67, 56, 45, 34, 23, 12, 1

It doesn't matter how many marbles Jason takes. He will lose on his 9th turn.

Mason's best strategy is to stay the overall variety of marbles at 11n+1, thus he can take ten marbles to begin. for every move Jason makes, Mason can take variety of marbles that creates the add from the 2 turns be eleven.

After every of Mason's nine turns, the amount of remaining marbles are

89, 78, 67, 56, 45, 34, 23, 12, 1

It doesn't matter what number marbles Jason takes. He can lose on his ninth flip.

Step-by-step explanation:

Given: [tex]y^2+3y=-1[/tex]

To solve for [tex]y[/tex], we need to get everything on one side of the equal sign and set it to zero. We can do this by adding 1 to both sides. We then get:

[tex]y^2+3y+1=0[/tex]

Plug in the values and simplify.

[tex]y=\frac{-3+\sqrt{(3)^2-4(1)(1)}}{2(1)}\\y=\frac{-3+\sqrt{5}}{2}\\-------------------------\\y=\frac{-3-\sqrt{(3)^2-4(1)(1)}}{2(1)}\\\\y=\frac{-3-\sqrt{5}}{2}\\[/tex]
