Answer:

see explanation

Step-by-step explanation:

This is a geometric sequence with explicit formula

$g_{n}$ = g(1) $(r)^{n-1}$

where g(1) is the first term and r the common ratio

Comparing this to the given explicit formula

$g_{n}$ = - 72 $(\frac{1}{6}) ^{n-1}$

with g(1) = - 72

and r = $\frac{1}{6}$

The recursive formula allows any term in the sequence to be obtained by multiplying the previous term by r, thus

g(n) = g(n - 1) × $\frac{1}{6}$

Which statement is true for the tables?

Flauer [41]

Answer:

Table A represents a function, but Table B does not represent a function.

Step-by-step explanation:

We have to select the correct option among the given 4 options after judging the given two tables attached to this question.

The first table shows that for each x values there is only one y value. Therefore, this is a function.

But in the second table shows that for each x value there are multiple y values since we are getting y = 1 and 2 for x = 5.

Hence, table B is not a function. it is just a relation. (Answer)

What is 1/3 written as an improper fraction

ad-work [718]

I'm pretty sure that you can not make these improper fractions; improper fraction just means the top number is bigger than the bottom. like 3/2 would be considered an improper fraction

A rock is thrown into a still pond. The circular ripple move outward from the point of impact of the rock so that the area of th

4vir4ik [10]

Answer:

$\approx 31.42 \text{ Square feet per minute}$

Step-by-step explanation:

Area of the Pond A= $\pi r^2$

The increase in the area of the pond as it moves outward is: $\frac{dA}{dt}$

$\frac{dA}{dt}=\frac{d}{dt}\pi r^2\\\frac{dA}{dt}= 2\pi r \frac{dr}{dt}$

Since the area of the circle formed increases at the rate of 100 square feet per minute.

$\frac{dA}{dt}$ = 100 Square feet per minute

When the radius, r = 5 feet, we want to determine the rate at which the radius is changing, $\frac{dr}{dt}$ .

$\frac{dA}{dt}= 2\pi r \frac{dr}{dt}\\100=2*5*\pi \frac{dr}{dt}\\\frac{dr}{dt} =\frac{100}{10 \pi} =10 \pi \approx 31.42 \text{ Square feet per minute}$

How far in feet will a child on the edge of the merry-go-round travel? If r=6 feet, the angle is 310

goblinko [34]

Answer:

First some theory we need to solve this problem.

For a circle of radius R, the perimeter is:

P = 2*pi*R

where pi = 3.14

If we have a section of this circle, defined by an angle θ, the length of this arc will be:

A = (θ/360°)*2*pi*R

In the case of the problem, the total distance that the child travels is equal to the length of an arc of 310° in a circle of radius r = 6ft.

Using the above formula, we know that the length of this arc is:

A = (310°/360°)*2*3.14*(6ft) = 32.4 ft
