The 12th term in the sequence is (c) f(n) = 354294

From the question, we have the following parameters that can be used in our computation:

The definition of the function is given as

-2, 6, -18, 54, ...

The above definitions imply that we simply multiply -3 to the previous term to get the current term

Using the above as a guide,

so, we have the following representation

f(n) = -2(-3)^n-1

Where

-2 is the first term and -3 is the common ratio

For the 12th term, we have

f(n) = -2(-3)^11

Evaluate

f(n) = 354294

Hence, the 12th term is (c) f(n) = 354294

The inverse of the function that indicates the amount Jake earns per hour at a local car wash is [tex]\mathbf{y =\dfrac{7.50}{x}}[/tex]

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a map or transformation. Typically, these functions are identified by letters like f, g, and h. etc

A function is an operation or a relation that links each individual element of a non-empty set X, to at least one element of another non-empty set Y.  In mathematics, a relation f between two sets, X and Y, is referred to as the function's domain and co-domain and can be expressed for all values of x and y as:

f = {(x,y)| for all x ∈ X,  y ∈ Y}

The objective of this question is to write the inverse of the given function.

The function f(x) = 7.50x correlates Jake's pay to the number of hours he puts in the work.

The inverse of the function can be written as:

y = 7.50x

Interchange the variables

x = 7.5y

Divide both sides by 7.5

x/7.5 = 7.5y/7.5

Symmetry is a way of measuring the shape of a data set. It is defined as the similarity between the upper and lower halves of a distribution.

A symmetric distribution is one where the data is equally distributed around a central point. To calculate this, you need to subtract the mean (the average of the values) from each data point and then divide by the standard deviation (the measure of how much the data is spread out). The formula for symmetry is: (x-mean)/standard deviation. An example of a symmetric distribution would be the scores of a group of students on an easy test. If the mean score was 70 and the standard deviation was 10, then any score between 60 and 80 would be considered symmetric.

Answer:Given Prove

PSUR is a rectangle QS = RT

PQ = TU

Proof:

Since PSUR is a rectangle, we know that opposite sides are parallel.

Therefore, PQ and TU are parallel.

Also, PSUR is a rectangle, so the angles P and R are right angles.

Therefore, angles Q and S are also right angles.

Since PQ and TU are parallel, and angles Q and S are right angles, we know that QS and RT are corresponding angles.

Therefore, QS=RT

Step-by-step explanation:

The height of the highest point of the trajectory and the horizontal distance the golf ball travels before hitting the ground will be 360 .6 meters

Apparently, x is the distance from the place where the ball is impacted on the ground.

The ball's horizontal speed, given by s, can be calculated using the equation cos(50) = s/60, where s = 38.5 mps.

Size is represented by f(x). The highest point of the parabola would be at -b/2a = -1.19/-.0066 = 180.3 metres, meaning the ball has moved 180.3 metres.

Input 107.28 metres into the formula to find the height.

In order to calculate the distance travelled, the ball must be on the ground, hence f(x) = 0.

-.0033x^2 + 1.19x = 0

x*(-.0033x + 1.19) = 0

x= 1.19/.0033 = 360 .6 meters

the value of function g[h(0)] at x = 0 is 3.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.

Given that,the functions f(x) = 3x, g(x) = x + 4 , and h(x) = x² − 1

Since,

G(h(x)) = x² - 1 +4

G(h(x)) =  x² + 3

Thus at x = 0

G(h(0)) =  0² + 3

G(h(0)) =  3

therefore, the value of function g[h(0)] at x = 0 is 3.

A decaying exponential function is given as follows:

y = a(1 - r)^x.

In which:

The initial value for this problem is of:

a = 16900.

After 8 years, the value was of 1400, hence the decay rate is obtained as follows:

16900(1 - r)^8 = 1400

(1 - r)^8 = 1400/16900

((1 - r)^8)^1/8 = (1400/16900)^1/8

1 - r = 0.73245368177

Hence the function is:

y = 16900(0.73245368177)^x.

2017 is 13 years after 2004, hence the value would be of:

In version 1, if you choose to stay with the card you have initially chosen, your chances of winning are 1 in 8, since you have a 1 in 8 chance of having selected an ace initially.

If you choose to switch, your chances of winning are 7 in 8, since the card you are switching to is randomly selected from the remaining 7 cards, 4 of which are aces.  However, if the card you have initially chosen is an ace, you should stay with it since you have already won the prize. If it is not an ace, it may be beneficial to switch as you have a higher chance of getting an ace with the face-down card.  

In either case, the dealer has a 7-in-8 chance of winning since he has access to all the cards and can choose the card to be revealed at random. This means that he has a higher chance of winning than the player does.  Overall, the game is quite balanced in terms of the chances of winning for either the player or the dealer.

The percent markup for the scooter that costs a retailer $75 but sells for $125 at the local store is 66.67%.

The markup is the additional price added to the cost of an item for retail sales.

Markups are usually expressed in percentages.

To express the markup in percent determine the difference between the retail price and the cost price.  Then divide the difference by the cost price and multiply by 100.

The cost price of the scooter = $75

The selling price of the scooter = $125

The markup in dollars = $50 ($125 - $75)

The markup percent = 66.67% ($50/$75 x 100)

Answer: To check if a given value is a root of the equation 8x-4 = 2, we can substitute the value into the equation and see if it makes the equation true.

When we substitute 3 for x in the equation 8x-4=2, we get 8(3)-4=2, which simplifies to 24-4=2, which is not true. So, 3 is not a root of the equation.

To check if a given value is a root of the equation 4y + 5 = y-7, we can substitute the value into the equation and see if it makes the equation true.

When we substitute -4 for y in the equation 4y + 5 = y-7, we get 4(-4) + 5 = -4-7, which simplifies to -16+5=-11=-4-7, which is true. So, -4 is a root of the equation.

a. The number of disappointed customers is 157. b. Unsold dolls = 135. c. The dolls needed per week is 660. d. The price of $0.63 will make the supply of the doll tight. e. The price at which the demand and supply will be at equilibrium is $3.20.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

a. The supply and the demand associated from the graphs are:

Supply: 95(2.50) - 60 = 178

Demand: -130(2.50) + 660 = 335

Subtracting the Demand and supply:

335 - 178 = 157

The number of disappointed customers is 157.

b. For unsold dolls set the equation for supply and demand:

Supply: 95(3.80) - 60 = 301

Demand: -130(3.80) + 660 = 166

Subtract the value of demand and supply:

301 - 166 = 135

Unsold dolls = 135

c. To give the dolls away, the cost of the doll is $0.

The demand equation thus becomes:

y = -130(0) + 660

y = 660

The dolls needed per week is 660.

d. Let the supply be 0.

y = 95x - 60

0 = 95x -60

x = $0.63

The price of $0.63 will make the supply of the doll tight.

e. The supply an demand will be in equilibrium when Demand = Supply, that is:

95x - 60 = -130x + 660

95x + 130x = 720

225x = 720

x = $3.20

The price at which the demand and supply will be at equilibrium is $3.20.
