What is the volume of the triangular prism below? V = ft 3
1 answer:
Answer:
50 ft³
Step-by-step explanation:
As your question is incomplete
Assuming diagram in the attachment shows a triangular prism:
(a) Calculate the volume of the prism if l = 5 ft.
A triangular prism has the same triangular cross-section throughout its length.
Volume = area of cross-section × length
= 10 ft² × 5 ft
= 50 ft³

Answer:
There would be $3,450.14 by the end of 4 months
There would be $4,623.78 by the end of 7 years.
Step-by-step explanation:
We are given the following in the question:
P = 3,400$
r = 4.4% = 0.044
Compounded monthly
Formula:
The compound interest is given by:
where A is the amount, p is the principal, r is the interest rate, t is the time in years and n is the nature of compound interest.
a) 4 months
There would be $3,450.14 by the end of 4 months.
b) 7 years
t = 7
There would be $4,623.78 by the end of 7 years.
Answer:
Step-by-step explanation:
We can start solving this problem by doing a drawing of London Eye. (See attached picture).
From the picture, we can see that the tourists will start at the lowest point of the trajectory, which means we can make use of a -cos function. So the function will have the following shape:
where:
A=amplitude
= angular speed.
t= time (in minutes)
b= vertical shift.
In this case:
A= radius = 67.5 m
where the frequency is the number of revolutions it takes every minute, in this case:
so:
and
b= radius, so
b=A
b=67.5m
so we can now build our equation:
which can be factored to:
You can see a graph of what the function looks like in the end on the attached picture.
