The required set of ordered pairs are (0, 1), (1, 3), (2, 9), (3, 27). The correct option is (D).

An exponential function can be represented as y = aˣ. When x = 0, y = a⁰ = 1. The range of an exponential function is from zero to infinity for a > 0.

It is clear from the given options that, only options (B) and (D) satisfies the general expression y = aˣ at x = 0.

Now, both these options can be examined one by one as follows,

Option (B),

The ordered pairs are given as (0, 1), (1, 2), (2, 5), (3, 10).

Substitute the values in the general expression y = aˣ, first two pair are satisfied for a = 2 but the remaining two are not.

Option (D),

The ordered pairs are given as (0, 1), (1, 3), (2, 9), (3, 27).

Substitute the values in the general expression y = aˣ, all the pairs are satisfied for a = 3.

Thus, the correct option is found.

Hence, the set of ordered pairs which could be generated by an exponential function are (0, 1), (1, 3), (2, 9), (3, 27).

Answer:

500 cm²  

Step-by-step explanation:

You haven't presented any diagrams, so I assume the prism has the dimensions shown below.

Then the dimensions of the original piece of cardboard are as in the second figure.

The area of the cardboard is the same as the lateral area of the triangular prism.

The formula for the area of a rectangle is  

A = lw

 l = 9 cm + 9 cm + 7 cm = 25 cm

w = 20 cm

A = 25 cm × 20 cm = 500 cm²

The area of the piece of cardboard is 500 cm².

Answer:

D - 150

Hope it helped :)

Answer:

150=w

Step-by-step explanation:

The answer is a little bit wordy. w = the sum of 85 + the supplement of 115.

So the first thing to do is get the supplement of 115.

180 - 115 = 65

w = 85 + 65 (These two are the remote interior angles. W is equal to the sum of them).

w = 150

Answer:

  3171 square meters

Step-by-step explanation:

You want the surface area of a 35 m square pyramid that has a volume of 8820 cubic meters.

The volume is given by ...

  V = 1/3s²h

so the height of the pyramid is ...

  h = 3V/s² = 3(8820)/35² = 21.6 . . . . meters

The slant height of one triangular face of the pyramid is found from the Pythagorean theorem:

  c² = a² +b²

  c² = 21.6² + 17.5² = 772.81

  c = √771.81 ≈ 27.799 . . . . . . meters

The surface area of the pyramid is the sum of the area of the square base and the lateral area of the four triangular faces.

  SA = s² + 4(1/2)(sc) = s(s +2c)

  SA = 35(35 +2·27.8) = 3171 . . . . square meters

The surface area of the Louvre Pyramid is about 3171 square meters.

Answer:

40 cm

Step-by-step explanation:

a square has 4 equal length sides, to get area you multiply two of those sides, 10 x 10 = 100, so each side is 10cm long, adding all of the sides together gets you 40cm.

Answer:

40cm

Step-by-step explanation:

We know that the formula for area of a square is side length squared or [tex]s^2[/tex]

In this case, [tex]s^2=100[/tex]. So we can go through the following steps in order to solve for s

[tex]s^2=100\\\sqrt{s^2} =\sqrt{100} \\\\s=10[/tex]

If one side equals 10, and we know all squares have 4 equal sides, then we can multiple 10 * 4 or add 10+ 10 + 10 + 10.

Our outcome is 40!

By using the combination formula to calculate the number of unique ways a group can be formed, we find that a coach can divide her 9-player squad into three equal groups in 5600 ways.

The student's question is about a concept in mathematics called combinations. A combination is a selection of items without regard to the order in which they are selected. In this particular problem, the tennis coach is dividing her 9-player squad into three equal groups. The number of ways this can be done uses the formula for combinations (nCr) where n equals the total number of items (in this case, players) and r equals the number of items being chosen at a time (in this case, the number of players in each group).

First, the coach can choose the first trio from the nine players using the combination formula 9C3. The second trio is chosen from the remaining 6 players, so this uses the formula 6C3, and for the third trio, which is chosen from the remaining 3 players, the formula is 3C3. Multiplied out, 9C3 x 6C3 x 3C3 equals 280 x 20 x 1 which is 5600. Therefore, there are 5600 unique ways the coach can divide her 9-player squad into three 3-player groups with each player in only one group.

Tristan's fish tank is 1/2 yard long,  1/6 yard wide, and  1/3 yard high. (Note that the fish tank is in the shape of a rectangular prism and not a cube.) One way of finding the volume of the tank is by dividing the tank into cubic blocks. What should the side lengths of each cubic block used to find the volume be?

Answer:

the side lengths are 3 sides, 1 side and 2 sides  of each cubic block.

Step-by-step explanation:

The volume of the rectangular prism is:

[tex](1/2 \ yard) * (1/6 \ yard) * (1/3 \ yard) = 1/36 \ yard^3[/tex]

However: let's find their lowest common multiples to determine their side length.

Multiples of 2:   2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, ...

Multiples of 6:   6, 12, 18, 24, 30, ...

Multiples of 3:   3, 6, 9, 12, 15, 18, 21, 24, 27, 30,  ...

The lowest common multiple for 2 , 6 and 3 is 6 .

Then in terms of the side length of each cubic block; we have :

1/2 × 6 = 3

1/6 × 6 = 1

1/3 × 6 = 2

So the side lengths are 3 sides, 1 side and 2 sides  of each cubic block

Answer:

358,000,000 BTU's.

Step-by-step explanation:

Given that the radius is equal to 5 ft. and we need to find the volume of sphere~we can use the following formula. Additionally, we will use 3.14159 to be more accurate in this case...

[tex]V =\frac{4}{3} \pi r^3\\V=\frac{4}{3} (3.14159)5^3\\V=4.18878667(125)\\V=523.6[/tex]

So the volume is 523.6 cubic ft!

To convert this to gallons...

[tex]\\1 ft^3 = 7.48052 gal\\523.6 ft^3 = 3916.8 gallons[/tex]

The final step is to multiply this amount by the original 91,500 BTU, when we do this we get...

[tex]3916.8*91500=358387200[/tex]

The nearest million from this number is 358,000,000!

Final answer:

To determine the number of BTUs a spherical storage tank provides, find the tank's volume in gallons by converting from cubic feet, then multiply by 91,500 BTU per gallon and round to the nearest million BTUs.

Explanation:

To calculate the number of BTUs a spherical storage tank can provide, given in gallons, we first need to know the tank volume in cubic feet. Let's assume the student provides this volume. Since 1 cubic foot is equivalent to approximately 7.48 gallons of liquid, we divide the volume in cubic feet by 7.48 to find the number of gallons of propane the tank can hold. Each gallon of propane yields approximately 91,500 BTU.

To find the total BTUs, we use the following steps:

Calculate the number of gallons in the tank by multiplying the volume in cubic feet by 7.48.

Multiply the number of gallons by 91,500 BTU per gallon to get the total BTUs in the tank.

Round the result to the nearest million BTUs, as the question asks.

For example, if a spherical storage tank has a volume of 100 cubic feet, the number of gallons it can hold would be 100 cubic feet * 7.48 gallons/cubic foot = 748 gallons. Then, the total BTUs would be 748 gallons * 91,500 BTU/gallon = approximately 68,442,000 BTU, which would then be rounded to 68 million BTUs.

Shannon's expression:

[tex]\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }[/tex]

Kristoph's expression:

[tex]\frac{4.2 \times 10^{2} }{1.4 \times 10^{-3} }[/tex]

Notice that both expression has the same coefficient numbers: 4.2 and 1.4. That means to have the same results, we just need to have the same powers.

Without dividing the complete expression, you can observe that both powers are the same, because each you subtract 9-4 = 5, and 2-(-3) = 5, both gives the same exponent to the power of 10.

Therefore, both expression give the same result, because they have the same numbers and the same powers.

Let's solve the division to have the result in scientific notation.

Shannon's expression:

[tex]\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }=3 \times 10^{9-4}=3 \times 10^{5}[/tex]

Kristoph's expression:

[tex]\frac{4.2 \times 10^{2} }{1.4 \times 10^{-3} }=3 \times 10^{2-(-3)}=3 \times 10^{5}[/tex]

The standard form refers to each number written without the power. To do so, we need to move the decimal points the number of spots as the exponent demands. Notice that the exponent is 5, that means, we need to move the decimal point 5 spots to the right.

[tex]3 \times 10^{5}=300000[/tex]

Therefore, the standard value of the expressions is 300,000.

Final answer:

To find the value of x for the given sequence, we must ensure the median remains 14. Since the median is the average of the third and fourth numbers in an ordered list of six numbers, x must be 16 because 9, 10, 12, 16, 20, 25 gives us a median of 14 (12 + 16 = 28; 28 / 2 = 14).

Explanation:

The student is asking to find the value of x in a sequence of numbers given that the median is 14. First, we place all the numbers in order: 9, 10, 12, x, 20, 25. Since there are six numbers, the median will be the average of the third and fourth numbers.

To have a median of 14, the sum of the third and fourth numbers must be 28 (since 14 = (third number + fourth number) / 2). Therefore, if the third number is 12, x must be 16 because 12 + 16 = 28.

The value of x that makes the median of the set equal to 14 is 16.

Answer:

Option A. 2

Step-by-step explanation:

From the question given, we were told that the total outcome in event A is 5.

Now if region 2 is 6, 7 or 8, as given in the other options, it therefore means that the total out in event A will be more than 5. So region 2 must be 2 in order to satisfy the event A.

Further more, considering the diagram, event B is bigger than event A. With this idea we can give the summary in diagram as follow:

Region 1 => 3 outcomes

Region 2 => 2 outcomes

Region 3 => 4 outcomes

Region 4 => 6 outcomes

Total => 15 outcomes

Now we can see that the total outcome correspond to the total outcome of 15 given in the question.

Therefore, region 2 has 2 outcome

Given the information, we can determine that B has 4 outcomes, but the number of outcomes specifically in region 2 cannot be found without additional information.

Let's break down the given information one piece at a time. The sample space (S) consists of 15 equally likely outcomes. Out of these, we know that 5 outcomes are in region A, and 6 outcomes neither belong to event A nor to event B.

Since events A and B are independent, they do not share outcomes. Now, we can calculate the number of outcomes in event B by subtracting the outcomes not belonging in A or B and belonging in A from the total outcomes. Hence, there are 15 - 5 - 6 = 4 outcomes in event B.

However, the question requires us to find outcomes in the second region (2). Since the regions were not specified concerning events A and B, we cannot identify the precise number of outcomes in region 2. Therefore, we cannot accurately answer the question with the given information.
