Answer:

D is the correct answer.

Step-by-step explanation:

When given points, one way to tell if it is a function is to see if the x-coordinate changes. If all the x-coordinates are different, then it is a function. If there is a group of x-coordinates that are the same, then you need to check the y-coordinate. If the y-coordinate is the same with the same x-coordinate, then it is still a function [Example: (12, 15), (12, 15) is a function, but (12, 15), (12, 18) is not)

Suppose that partners equally share the profits from a sale of $3,600. Which algebraic expression represents this situation?

iVinArrow [24]

Answer:

The last algebraic expression $\frac{3600}{p}$ represents this situation.

Step-by-step explanation:

There is a mistake in the last option it would be 3600/p.

Given:

Suppose that partners equally share the profits from a sale of $3,600.

Now, to find the algebraic expression represents this situation.

Let the partners be $p.$

Amount of sale = $3,600.

So, as the partners equally share the profits we divide the amount of sale by the partners $p$ :

$3600\div p\\\\=\frac{3600}{p}$

Therefore, the last algebraic expression $\frac{3600}{p}$ represents this situation.

Answer:

5 Soup can

Step-by-step explanation:

If 3 soup can cost $3.75

Then 1 soup can will cost $3.75/3

So, how many can soup will cost $6.25

= $6.26/(cost of 1 soup can)

= $6.25/($3.75/3)

=$6.25 × 3÷ 3.75

= 5 cans of soup

Can someone explain what geometric sequences are?

Fed [463]

Explanation:

A sequence is a list of numbers.

A geometric sequence is a list of numbers such that the ratio of each number to the one before it is the same. The common ratio can be any non-zero value.

Examples

1, 2, 4, 8, ... common ratio is 2
27, 9, 3, 1, ... common ratio is 1/3
6, -24, 96, -384, ... common ratio is -4

___

General Term

Terms of a sequence are numbered starting with 1. We sometimes use the symbol a(n) or an to refer to the n-th term. The general term of a geometric sequence, a(n), can be described by the formula ...

a(n) = a(1)×r^(n-1) . . . . . n-th term of a geometric sequence

where a(1) is the first term, and r is the common ratio. The above example sequences have the formulas ...

a(n) = 2^(n -1)
a(n) = 27×(1/3)^(n -1)
a(n) = 6×(-4)^(n -1)

You can see that these formulas are exponential in nature.

Sum of Terms

Another useful formula for geometric sequences is the formula for the sum of n terms.

S(n) = a(1)×(r^n -1)/(r -1) . . . . . sum of n terms of a geometric sequence

When |r| < 1, the sum converges as n approaches infinity. The infinite sum is ...

S = a(1)/(1-r)

OK so I have two questions to answer. So the first picture is question five in the second picture is question six.

Vesnalui [34]

Answer:

The slope is 2.25

The y-intercept is 3

Step-by-step explanation:

Assuming from the cut off picture, that we need to find the slope of ...

y=2.25x +3

y=mx+b form makes it easy to identify the slope and the y-intercept.

m is the slope and b is the y-intercept. Anything number that is in place of m, is the slope; and any nother in place of b is the y-intercept.

In that case, 2.25 is the slope and 3 is the y-intercept

True or false and why: if a and b are irrational, then a^b is irrational

FrozenT [24]

False

b could be the logarithm of a rational number to the base a. For example,

$b=\log_\pi{(4)}$ will be irrational, but π^b = 4, a rational number
