Answer:
Step-by-step explanation:
The explicit formula for a GP is expressed as
Tn = ar^{n-1}
a is the first term
n is the number of terms
r is the common ratio
a) If a3 = 36 and r = 6
a3 = ar^3-1
a3 = ar^2 = 36
ar^2 = 36
a(6)^2 = 36
36a = 36
a = 1
Get the nth term
Tn = 1(6)^{n-1}
Tn = 6^{n-1}
b) If a6 = 64 and r = 2
a6 = ar^6-1
a6 = ar^5 = 64
ar^5 = 64
a(2)^2 = 64
4a = 64
a = 16
Get the nth term
Tn = 16(2)^{n-1}
Tn = 16*(2^n/2)
Tn = 8(2^n)

Brianna wants to use a pontoon boat on Saturday at the lake. She has exactly
$200 to spend on the boat rental. The rental is $30 an hour plus a $80 deposit.
How many hours can she rent the pontoon boat for? Create and solve an
equation for this situation.
Answer:
Step-by-step explanation:
She has 200
80 deposit - 200= 120 left to spend
80+30h=200
If she has 120 left to spend at 30 hr, she could have the boat for 4 hrs
80+30h=200 subtract 80 from both sides
30h=120 divide by the 30
h=4

Answer: In the Instance that she downloads 45 songs, she would pay $40.75. The equation for s songs in one month would be
Money = 7 + s(0.75)
Well, since the time span is a month we can say M is money and n is the amount of months she listens. since this is one month we know N equals 1.
So M = 7n + s(0.75)
7 being the monthly fee, n being the amount of months using the service, s being the amount of songs downloaded, and 0.75 being the cost of every song downloaded.

Linear Equations with explanation plz
help, thank you so much!
Answer:
-2
Step-by-step explanation:
The average rate of change over [a, b] is simply the slope of the function over [a, b] because:
[tex]let\:g(x)=f'(x)\\\frac{\int\limits^b_a {g(x)} \, dx }{b-a} = \frac{f(b)-f(a)}{b-a}[/tex]
We have to find the avg ROC over [-3, 1] so the slope over the interval is
[tex]\frac{f(1)-f(-3)}{1-(-3)} = \frac{-6 - 2}{4} = \frac{-8}{4} = -2[/tex]

Joseph received a $20 gift card for downloading music. Each downloaded song costs $1.29. Explain how to write and solve an inequality that can be used to determine the number of songs that he can purchase.
Interpret the solution.
Answer:
Step-by-step explanation:
Answer:
Let x be the number of songs downloaded.
Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs, or 1.29x.
This cannot be more than 20, so we set this less than or equal to 20:
1.29x ≤ 20.
To solve this, we divide both sides by 1.29:
≤ ;
x ≤15.5.
We cannot download half of a song, so we round this down to 15 (although the number rounds up mathematically, he would not have enough money to download 16 songs). This means he can download at most 15 songs.
Step-by-step explanation:
if you want the sample response then here: If x represents the number of downloads, you can write the inequality 1.29x ≤ 20. Solving the inequality, you find that x is less than or equal to about 15.5. Since he can’t download part of a song, Joseph can download 15 or fewer songs.
Solve for x. Please answer correctly !!!!!!!!!!!!!!! Will mark brainliest !!!!!!!!!!!!!!!!!!!!
