Answer:

Step-by-step explanation:

The nth term ( explicit formula) of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 2 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{\frac{4}{3} }{-2}[/tex] = - [tex]\frac{2}{3}[/tex] , then

[tex]a_{n}[/tex] = - 2 [tex](-\frac{2}{3}) ^{n-1}[/tex] ← explicit formula

Answer:

Step-by-step explanation:

The formula for an explicit geometric formula (as opposed to a recursive one) is

[tex]a_n=a_1(r)^{n-1}[/tex] where a(n) is representative of the position of a number in the sequence, a(1) is the first number in the sequence, and r is the common ratio. The common ratio is the same number that must be either multiplied in or divided out to get to the next number in the term. Notice that the top numbers in our sequence are doubling which implies we are multiplying the top numbers by -2, and the bottom numbers are going up by multiples of 3. So our common ratio is -2/3. Try it and see:

[tex]-2(-\frac{2}{3})=\frac{4}{3}[/tex]  and

[tex]\frac{4}{3}(-\frac{2}{3})=-\frac{8}{9}[/tex] etc.

Therefore, the explicit geometric formula for this sequence is

[tex]a_n=-2(-\frac{2}{3})^{n-1[/tex]

You can use this formula to find any number in the sequence; for example, if you wanted to know the 100th number in this sequence, simply replace n with 100 and do the math. That's what an explicit formula is used for.

Answer:

Option (4)

Step-by-step explanation:

Proportional relationship means,

y ∝ x

y = kx

[tex]k=\frac{y}{x}[/tex]

Here, k = proportionality constant

Therefore, if the graph of a line passes through the origin (0, 0) table will represent the proportional relationship.

From table 1,

For a point (1, 2)

[tex]k=\frac{2}{1}=2[/tex]

For another point (3, 2)

[tex]k=\frac{3}{2}=1.5[/tex]

In both the cases 'k' is not same of constant.

Therefore, table (1) is not proportional.

For table (2),

Line passes through (2, 0).

That means there is a x-intercept → (2, 0)

Therefore, table doesn't represent a proportional relationship.

For table (3),

Line passes through a point (0, 1)

It means given line has a y-intercept → y = 1

Therefore, table doesn't represent a proportional relationship.

For table (4),

Line of this table passes through two points (1, 3) and (2, 6)

[tex]k=\frac{3}{1}=3[/tex]

[tex]k=\frac{6}{2}=3[/tex]

Therefore, proportionality constant for the given table is 3.

Now we can graph table (4).

Answer:

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

the theoretical probability that the movie is not a comedy = number of movies that are not comedies / total movies available

Answer: Outsourcing

Step-by-step explanation: I just took a test.

The use of workers that use networked computers to work at lower rates of pay than American workers is called outsourcing.

The term outsourcing has to do with a situation in which workers from outside the company are contrated to do the work of the company. This could be done remotely most times by the use of a computer.

In this case, the American companies that contracted European and Asian companies, where well educated workers could do jobs on networked computers at lower rates of pay than American workers is called outsourcing.

Answer:

GH 5000

Step-by-step explanation:

Given data

Cost price=  GH 2000.00

Percent profit= 60%

Sales price =???

The sale price can be found  as

% profit= sale-cost/sale*100

60= sale-2000/sale*100

60= 100*sale-200000//sale

60*sale= 100sale-200000

1000sale-60sale= 200000

40sale= 200000

sale= 200000/40

sale= 5000

Hence the sales price = GH 5000

Answer: C. 1/3π(7.52)(19) – 1/3π(3.52)(8)

Step-by-step explanation:

took the test and got 100

The expression that represents the volume of the frustum is:  1/3π(7.5²)(19) - 1/3π(3.5²)(8).

Volume of a frustum = Volume of bigger cone - volume of smaller cone = 1/3πR²H - 1/3πr²h

Given the following dimensions:

Applying the volume formula, we have:

Volume of the frustum = 1/3πR²H - 1/3πr²h = 1/3π(7.5²)(19) - 1/3π(3.5²)(8)

Thus, the expression that represents the volume of the frustum is:  1/3π(7.5²)(19) - 1/3π(3.5²)(8).

Answer:

The answer would be the first one, combining 8 and -2

Step-by-step explanation:

This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)

If you combine these you will get 6x^2 [8+(-2)=6]
