The first three terms of a geometric
sequence are 3, 6, 12.
The next three terms in the geometric sequence will be 24, 48 and 96.
We are given a geometric sequence:
3, 6, 12 …
We need to find the next 3 terms of the sequence.
We can see that:
a = initial term of the sequence
a = 3
r = common ratio between the consecutive terms.
r = 6 / 3 = 2
Now, nth term will be represented by:
aₙ = a rⁿ⁻¹
Substituting the values of a and r in the formula, we get that:
aₙ = 3 (2)ⁿ⁻¹
Now, the 4th term will be ( put n = 4)
a₄ = (3) (2)⁴⁻¹
a₄ = (3) (2)³
a₄ = (3) × (8)
a₄ = 24
The 5th term will be: (put n = 5)
a₅ = (3) (2)⁵⁻¹
a₅ = (3) (2)⁴
a₅ = (3) × (16)
a₅ = 48
6th term will be: (put n = 6)
a₆ = (3) (2)⁶⁻¹
a₆ = (3) (2)⁵
a₆ = (3) × (32)
a₆ = 96
Therefore, the next three terms in the geometric sequence will be 24, 48 and 96.

Which of the relations shown does NOT represent y as a function of x?
The graph which does not represent y as a function of x is (B) as a line drawn can't touch the graph at two points.
The function that dose not show y as a function of x.
Y is a function of X, means that a certain variable magnitude or phenomenon Y is determined/caused by another magnitude or phenomenon X, such that the behavior of X will affect that of Y. In logic, a function symbol is a logical symbol that may be applied to an object term to produce another object term.
If a vertical line is drawn such that it touches more than one place, then it is not a function of x.
Here also if a vertical line will be drawn it will touch two places in the curve.

As a line created can't touch the graph at two locations, graph (B) does not represent y as a function of x.
The function that hides y's relationship to x.
A variable's magnitude or phenomena Y is determined by or caused by a different variable's magnitude or phenomenon X, meaning that X's behavior will have an impact on Y's. A function symbol in logic is a logical symbol that can be used to transform one object term into another.
A vertical line is not a function of x if it is drawn so that it touches many locations.

The following table shows the average total cost, measured as dollars expended per pupil, of operating a high school with the given enrollment. This table is based on a study of economies of scale in high school operations from the 1960s.
Enrollment: 170 250 450 650
Average total cost: 538 473 411 415
Estimate the average cost per student for a high school with an enrollment of 350 students.
The interpolated value for an enrollment of 350 students is $ ------
per student.
Answer:
$433
Step-by-step explanation:
You want the average cost per student for an enrollment of 350 students as interpolated from a table of enrollments and costs.
InterpolationThere are a number of ways the cost table might be interpolated. The one used here is to use quadratic regression to write a formula for the cost as a function of enrollment. Then the function value for 350 students is found. This is all accomplished using a graphing calculator, as shown in the attachment. The interpolated value for an enrollment of 350 students is $433 per student.
Another method of interpolation could use linear interpolation between the two nearest points. Our enrollment of interest, 350, is halfway between 250 and 450, so the cost per student could be estimated to be halfway between 473 and 411:
cost per student = (473 +411)/2 = 442 . . . dollars per student
We know this estimate is a bit high, because the cost function is concave upward. A straight line between two points on the curve will lie above the curve.
Other methods of interpolation will give other values. A cubic interpolating function gives a value of $428 per student.

The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1/5 is 5/1) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.In other words - five divided by one fifth is twenty-five.

A real-world situation where you can apply the unit rate is finding the cost of a single can of soda from a pack of soda.
How can you use the unit rate?The unit rate refers to the price of a single item out of a number or group of items. It is found by dividing the total price of the group of items by the number of items in the group.
In a real-world scenario, you might see a pack of soda priced at $5.20 and you need to know the price of a single can of soda. You can find this by the formula:

Ken invested $10,000 in two bank accounts. One of the accounts pays 4% annual interest, and the
other account pays 6% annual interest. If the combined interest earned in both accounts after a
year was $514, how much money was invested in each account?
Ken invested $5,700 in the 6% account, and the other $4,300 in the 4% account.
How much money was invested in each account?Let's define the variables:
x = amount of money on the 4% account.y = amount of money on the 6% account.We know that Ken invested $10,000 in total, so:
x + y = 10,000
And the interest in one year is:
x*0.04 + y*0.06 = 514
Then we have a system of equations:
x + y = 10,000
x*0.04 + y*0.06 = 514
To solve it we start by isolating one of the variables in one of the equations, isolating x we will get:
x = 10,000 - y
Replacing that in the other equation we get:
(10,000 - y)*0.04 + y*0.06 = 514
400 - y*0.04 + y*0.06 = 514
400 + y*0.02 = 514
y = (514 - 400)/0.02 = 5,700
Then Ken invested $5,700 in the 6% account, and the other $4,300 in the 4% account.
