The difference between these two figures is the shape of the base.
Prisms are "named" by their bases.
A rectangular prism has a rectangular base, a triangular prism has a triangular base, a square prism would have a square base, etc.
Answer:
<em>The interest earned is $302.18</em>
Step-by-step explanation:
<u>Compound Interest
</u>
It occurs when the interest is reinvested rather than paying it out. Interest in the next compound period is earned on the principal sum plus previously accumulated interest.
The formula is:
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
The investment described in the question is of P=$600 at a rate of r=6%=0.06 for t=7 years compounded annually. The compounding period coincides with the time of interest rate, thus n=1.
Applying the formula:
A = $902.18
The interest is:
I = A - P = $902.18 - $600 = $302.18
The interest earned is $302.18
Answer is A) -1 because it they are parallel then they have the same slope. If the green line has a -1 slope so does the red line
For this case we have the following equation:
h = -16t2 + 64t + 80
To find the maximum height, we derive the equation:
h = -32t + 64
We match zero:
-32t + 64 = 0
We clear t:
t = 64/32
t = 2
We substitute the value of t in the given equation:
h (2) = -16 * (2) ^ 2 + 64 * (2) + 80
h (2) = 144
Answer:
The maximum height is 144 feet and the time to reach this height is 2 seconds.
1. 40% - 25%
ANSWER = 15%
2. There are 24 guests. 1/3 is 8 guests (drinks). 1/4 is 6 guests (desserts). The remaining guests (chips) = 24 - (8+6)
= 24 - 14.
ANSWER: 10 guests brought chips.
3. Not 100% sure about this one, though.
The area is 1112 ft x 912 ft = 1014144 sq ft. You divide the area of the kitchen by the area of the tile (144 sq ft), which is 7042.666667. Because its not a whole number, one of the tiles won't fit completely, so you get rid of it completely and round the number down.
ANSWER = 7042 tiles ???
4. Use BIDMAS for this one (Brackets, Indices, Divison, Multiplication, Addition, Subtraction)
-2[4^2 + (12)2]
Get rid of the (12) first
-2(4^2+24)
Now the other brackets.
4^2 (or 4 squaresquared, with the little 2) is 16, so you do 16+24.
-2(40) or -2 x 40
ANSWER = -80
