You can find it by the original equation
2=(1+r)^12
r=(2)^(1÷12)−1
R=0.0595*100=5.95%
3=(1+0.0595)^t
t=log(3)÷log(1.0595)
t=19 years
Answer:
For , r = 2 units and h = 1 unit
For , r = 1 unit and h = 4 units
Step-by-step explanation:
Given: cylinders
To find: two different combinations of radius and height that produce two cylinders with nearly the same volume
Solution:
Let represents two cylinders.
For cylinder :
Radius (r) = 2 units
Height (h) = 1 unit
Volume of cylinder = cubic units
For cylinder :
Radius (r) = 1 unit
Height (h) = 4 units
Volume of cylinder = cubic units
Therefore,
cylinders have same volume.
Answer: choice C) -15x^4y
-----------------------------------------
Explanation:
The coefficients are -3 and 5. They are the numbers to the left of the variable terms
Multiply the coefficients to get -3*5 = -15. So -15 is the coefficient in the answer
Multiply the x terms to get x^3 times x = x^(3+1) = x^4. Notice the exponents are being added
Do the same for the y terms as well: y^2 times y^(-1) = y^(2+(-1)) = y^(2-1) = y^1 = y
So we have a final coefficient of -15, the x terms simplify to x^4 and the y terms simplify to just y
Put this all together and we end up with -15x^4y which is what choice C is showing
The mean or better known as the average is all of the numbers combined and then divided by how many numbers there were. You should be able to find the mean of any set of numbers. There might be a mistake in the calculations some where.
