Lelu [443]3 years ago

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

4.05, 1.35, 0.45, 0.15, ...

Since it is a geometric sequence.

So, here, a = 4.05

r = \dfrac{a_2}{a_1}=\dfrac{1.35}{4.05}=0.33

So, we know the formula for nth term in geometric sequence.

a_n=ar^{n-1}\\\\a_n=4.05(0.3)^{n-1}

Hence, First option is correct.

Phantasy [73]

Answer:

f(x)=-\frac{1}{2}x +1

Step-by-step explanation:

Slope intercept form is: f(x)=mx+b

<h2>Find the Slope:</h2>

Choose 2 points on the graph:

(0,1) (2,0)

Find the slope of the two points:

\frac{0-1}{2-0}=-\frac{1}{2}

m=-\frac{1}{2}

<h2>Find the Y-Intercept</h2>

The y-intercept, or the point that the line crosses on the y axis, is (0,1).

b=1

f(x)=-\frac{1}{2}x +1

liberstina [14]

Answer:

g/8 - 17

Step-by-step explanation:

Number of employees = 8

Total games sold = g

Average sales per employee = total games sold / number of employees = g/8

Chris sold 17 fewer games than the average sales per employee :

Chris sale = average sale per employee - 17

Chris sales = g/8 - 17

Carmen wants to join a gym. Gym A costs $26.76 plus an additional $4 for each visit. Gym B has no initial fee but costs $12.92 f
joja [24]

Answer:

After 3 visits both plans will cost the same.

Step-by-step explanation:

Gym A costs $26.76 plus an additional $4 for each visit.

Gym B has no initial fee but costs $12.92 for each visist.

The cost for gym A can be written as

C= $26.76 + 4(x)  where x is the number of visits to the gym A

The cost for gym B can be written as

C= $12.92 (x)  where x is the number of visits to the gym B

Both costs will be equal

12.92x= 26.76 +4x

12.92x-4x= 26.76

8.92x= 26.76

x= 26.76/8.92

x= 3

after 3 visits both plans will cost the same.

Check

12.92x= 26.76 +4x

12.92*3= 26.76 +12

38.76= 38.76
