Lets find out...
a^2 + b^2 = c^2
27^2 + 79^2 = 84^2
729 + 6241 = 7056
6970 = 7056....incorrect....no, it is NOT a right triangle
I believe it’s z=17
w=24
24-7= 17
Answer:
The radius is decreatsing at a rate 0.78 cm per second.
Step-by-step explanation:
We are given the following in the question:
Instant radius,r = 2 cm
Instant length,l = 9cm
The radius of the cylinder decreases.
Volume of cylinder =
Since the volume of the cylinder does not changes, we can write:
Rate of change of volume:
Puttiung values, we get
Thus, the radius is decreatsing at a rate 0.78 cm per second.
For this case, the first thing we are going to do is model the desk as a rectangle.
The area of the rectangle is given by:
A = w * l
Where,
w: width
l: length
Clearing we have:
l = A / w
Substituting values:
l = (15/16) / (5/4)
Rewriting we have:
l = (15/16) * (4/5)
Simplifying we have:
l = (3/4) m
Answer:
The length of the desk in meters is:
l = (3/4) m
The interest is $315.00. The formula is the simple interest formula: I= P x R x T. You multiply the principal amount which is the starting $ amount, times the interest rate, times the amount of time. Hope this helped :)
