Answer:

Each notebook costs $2

Step-by-step explanation:

We have to find the amount she spent on each notebook.

The volume of a certain right circular cone is 30 cubic inches. What is the volume, in cubic inches, of a second right circular
mrs_skeptik [129]

Answer:

V = 15 in.³

Step-by-step explanation:

The original cylinder has radius r and height h.

V = πr²h

Its volume is 30 in.³, so

πr²h = 30 in.³

The new cylinder has radius (1/2)r and height 2h.

Its volume is

V = π(r/2)²(2h)

V = πr² × 2h/4

V = πr²h/2

πr²h is the volume of the original cylinder, and it is 30 in.³.

V = 30 in.³/2

V = 15 in.³

F(1)=6;f(n)=f(n−1)−2
ch4aika [34]

Answer: f(7) = f(4) + 3(3) = 15 + 9 = 24

Step by Step Explanation:

f(1) = 6

f(n) = f(n-1) + 3

 

f(2) = f(1) + 3 = 6+3 = 9

f(3) = f(2) + 3 = 12

f(4) = f(3) + 3 = 15

 

Each term is 3 more than the previous one  

Therefore to get from the 4th term to the 7th term you will add 3

For a total of 3 more times.

 

f(7) = f(4) + 3(3) = 15 + 9 = 24

Hope this helps

using compound interest, how long does it take to double a 1000 dollar investment that pays 6.5% annual interest, compounded mon
KonstantinChe [14]

Answer:

11 years approx

Step-by-step explanation:

Given data

P=$1000

A=2000

R=6.5%

T= ?

Calculate time, solve for t

t = ln(A/P) / r

substitute

t=ln(2000/1000)/0.065

t=ln(2)/0.065

t=0.693/0.065

t=10.66

Hence the time is 11 years approx
