Answer:

1st one is "square root of 2x"

2nd one is "2 square root of x"

3rd one is "is not"

Step-by-step explanation:

1st one: you have 2x for g(x) then you plug that into the x for f(x) giving you square root of 2x

2nd one: you have square root of x for f(x) then you plug that into the x for g(x) giving you 2 square root of x

3rd one: the inverse of the square root of x is x^2

Which equations represent inverse variation? Check all that apply.

Bogdan [553]

For this case, what you should know is that the equations that represent an inverse variation are those that could not form a straight line, for example.

We have then:
Equation 1:
pv = 13
Rewriting:
p = 13 / v
P and v are represent an inverse variation.
Equation 2:
z = (2 / x)
z and x are represent an inverse variation.
Answer:
equations represented inverse variation are:
pv = 13
z = (2 / x)

For her phone service, Martina pays a monthly fee of $25, and she pays an additional $0.07 per minute of use. The least she has

Mekhanik [1.2K]

Answer: Anything that is 1202 or larger

In other words, $m \ge 1202$

So we could have m = 1202, or m = 1203, or m = 1204, etc.

===============================================

Explanation:

m = number of minutes used
0.07m = amount charged for those minutes used excluding the $25
0.07m+25 = total monthly bill now including the extra $25 fee

The monthly bill is at least $109.14, since this is the lowest amount she has been charged.

$\text{monthly bill} \ge 109.14\\\\0.07m+25 \ge 109.14\\\\0.07m \ge 109.14-25\\\\0.07m \ge 84.14\\\\m \ge \frac{84.14}{0.07}\\\\m \ge 1202\\\\$

This says that the least number of minutes Martina has used is 1202 minutes.

So if m was a whole number, then m could be selected from the set {1202, 1203, 1204, ...}

Side note: 1202 minutes = 1202/60 = 20.033 hours approximately.

Can you guys help me with this?

Blababa [14]

Answer:

We have been given many sequences below:

The sequence is said to be geometric if there is same ratio between consecutive terms

$\frac{a_n}{a_{n-1}}$

So we will check all the sequences one by one:

(1) $\frac{-9}{-2.7}=\frac{10}{3}$

$\frac{-30}{-9}=\frac{10}{3}$

$\frac{-100}{-30}=\frac{10}{3}$ .

Hence, geometric

(2) $\frac{2.5}{-1}=-2.5$

$\frac{-6.25}{2.5}=-2.5$

$\frac{15.625}{-6.25}=-2.5$

Hence, geometric.

(3) $\frac{9.2}{9.1}=0.010$

$\frac{9.3}{9.2}=0.010$

$\frac{9.4}{9.3}=0.010$

Hence, geometric.

(4) $\frac{0.8}{8}=0.1$

$\frac{0.08}{0.8}=0.1$

$\frac{0.008}{0.08}=0.1$

Hence, geometric.

(5) $\frac{-4}{4}=-1$

$\frac{-12}{-4}=3$

Ratio is not same hence, not geometric.
