Answer: C. [tex]f(n) = -4(-3)^{n-1}[/tex]

Step-by-step explanation: The formula for a geometric sequence is [tex]ar^{n-1}[/tex], where a = first term in the sequence

r = common ratio

n = position of term

Here they already told us a = -4, so we have to figure out r. We can see that in the sequence -4, 12, -36, 108... the terms are being multiplied by -3, which is why the negative and positive terms alternate.

Therefore, the formula is: [tex]f(n) = -4(-3)^{n-1}[/tex]

You can try inserting n to check it.

[tex]f(1) = -4(-3)^{1-1} = -4\\f(2) = -4(-3)^{2-1} = 12\\f(3) = -4(-3)^{3-1} = -36\\f(4) = -4(-3)^{4-1} = 108[/tex]

Option C

Let's verify

Hence verified

Hello.

Use the Distributive Property which states

a(b+c)=ab+ac

Hey there!

The Distributive Property states that

a(b+c)=ab+ac

where

a, b, and c can be either constants or variables.

Now that we know what the property states, let's simplify:

3(9k-1)

multiply:

3 times 9k and 3 times -1

27k-3

Hope everything is clear.

Answer:

$28.50

Step-by-step explanation:

21 chicken wings= $39.90

1 chicken wing= 39.90÷21= $1.90

15 chicken wings= 15×1.90= $28.50

:)

Answer:

$28.50

Step-by-step explanation:

Knowing that :
Brandon brought 21 chicken wings for $39.90

Asking:

How much would it cost for 15 Wings?

Solve:

We first need to know how much is 1 Wings.

To find that Divide Cost by chicken

Thus, 39.90 divide by 21..

=1.90

Hence, 1 Wings ⇒ 1.90

Then Multiply by 15 wings to find the cost of 15 wings.

1.90 * 15 = 28.50

Therefore, 15 Wings Cost $28.50

The height of the baseball after the 1.5 seconds of time as the boy throw the ball is 15.5 meters.

The mathematical functions is used to represent the general problem in the mathematical way to solve them.

Steps to write down the simple mathematical function-

A boy throws a baseball across a field. The ball reaches its maximum height, 18 meters, after 1 second.

After approximately 2.3 seconds, the ball lands on the ground.

The ball’s motion can be modeled using the function

[tex]f(x) = -10x^2 +20x+ 8[/tex]

Here, x represents the time in seconds.

As, the height of the ball 1.5 seconds after it is thrown has to be found out. Thus, put the values of in the above equation as,

[tex]f(x) = -10(1.5)^2 +20(1.5)+ 8\\f(x)=-22.5+30+8\\f(x)=15.5\rm \; m[/tex]

Hence, the height of the baseball after the 1.5 seconds of time as the boy throw the ball is 15.5 meters.

Answer:

2 4/9 because the filled in boxes stand for a whole and what's missing is 4 pieces from the last one which would be the numerator and the denominator would be 9 because that's how many squares are there in total.

Step-by-step explanation:

Answer:

2 5/9

Step-by-step explanation:

Count the full boxes, which there are two of them,
and then you count the number of colored boxes in the partially filled one.
There are 5 colored boxes.

Hence, you get 2 wholes and 5/9 colored boxes

So the answer is 2 5/9.

Using the z-distribution, as we have the standard deviation for the population, it is found that the smallest sample size required to obtain the desired margin of error is of 77.

The confidence interval is:

[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

The margin of error is given by:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In this problem, we have that the parameters are given as follows:

[tex]M = 3, z = 1.645, \sigma = 16[/tex].

Hence, solving for n, we find the sample size.

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]3 = 1.645\frac{16}{\sqrt{n}}[/tex]

[tex]3\sqrt{n} = 1.645 \times 16[/tex]

[tex]\sqrt{n} = \frac{1.645 \times 16}{3}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.645 \times 16}{3}\right)^2[/tex]

[tex]n = 76.97[/tex]

Rounding up, the smallest sample size required to obtain the desired margin of error is of 77.

Answer:

$68.00

Step-by-step explanation:

16 x 425 = 6800

Just move the decimal 2 places to the left to get 68

Matthew spends $68 on gas as the rate of gas is $4.25 per gallon.

Per unit is a technique of expressing a quantity's value in terms of a base or reference quantity. Each system variable or quantity in a per-unit system is normalized in relation to its own base value.

Given Matthew bought 16 gallons of gas for $4.25 per gallon.

Since the price per gallon = 4.25

The price of the gas for 16 gallons = 4.25 * 16

The price of the gas for 16 gallons = 68.00

Therefore, Due to the $4.25 per gallon price, Matthew spends $68 on gas.

Answer:

  a) r(b) = 75b

  b) c(b) = 30b +500

Step-by-step explanation:

Revenue is the product of the selling price per unit and the number of units. The cost will be the sum of fixed (overhead) cost and production cost per unit multiplied by the number of units produced.

__

Let b represent the number of skateboards Jesse produces in a month.

Jesse receives $75 for each skateboard sold. Her revenue from selling 'b' skateboards is ...

  r(b) = 75b

__

It costs Jesse $30 for each skateboard produced, and $500 for overhead. Her total cost is ...

  c(b) = 30b +500

_____

Additional comment

In order to break even, Jesse's revenue must equal her cost:

  75b = 30b +500

  45b = 500

  b = 11 1/9

Jesse must produce and sell 12 skateboards each month to cover her costs. (In a real business, there are additional considerations related to inventory, shrinkage, returns, discounts, and other things that may increase cost or reduce revenue.) After covering costs, each additional skateboard sold will give Jesse a profit of $45.

i don't know I don't have ideas

Answer:

Step-by-step explanation:

Two equations can be written to describe the desired relationships. One can describe the total quantity of gold alloy needed. The other can describe the amount of gold in the combination of alloys.

Let x and y represent the quantities in grams of 85% and 70% gold alloy needed, respectively.

  x + y = 20 . . . . . . Shannon needs a total of 20 grams

  0.85x +0.70y = 0.80(20) . . . . . the amount of gold in the mix of alloys

__

These equations are often nicely solved by substitution. Substituting for y, we have ...

  0.85x +0.70(20 -x) = 0.80(20)

  0.15x = 0.10(20) . . . . . . . eliminate parentheses, subtract 0.70(20)

  x = 40/3 = 13 1/3 . . . . . divide by 0.15

  y = 20 -13 1/3 = 6 2/3

Shannon should use 13 1/3 grams of 85% alloy and 6 2/3 grams of 70% alloy.
