Answer:
.
Step-by-step explanation:
Given : sequence which has a first term of 14 and has a common ratio of 1.03.
To find :Find the 12th term of the sequence .
Solution : We have given first term of 14 and has a common ratio of 1.03.
Sum of n terms ( .
Where, a = first term , r = common ratio and n = number of terms .
Then, Plug the values a = 14 , r = 1.03 , n = 12.
.
.
.
.
Therefore, .
Answer:
The rate is 1.75 feet/seconds or 105 feet/minute.
Step-by-step explanation:
Given that,
Li walks at a constant rate of 7 feet in 4 seconds
To find the constant of proportionality, divide 7 feet by 4 seconds.
So,
1.75 ft/s is the constant of proportionality
We know that, 1 minute = 60 seconds
k = 105 feet/minute
So, the rate is 1.75 feet/seconds or 105 feet/minute.
Answer:
The surface area of the gift box is =
Step-by-step explanation:
The surface area of the cylinder can be calculated using this formula:
in this case, r is not a number, but rather an expression, which is r = .
The height of the gift box is twice the radius, which is h =
To get our curved surface area, we carefully put the expressions for h and r into the equation.
The surface area of the gift box is =
