Answer:
It will take an interest rate of 8.1% to get 150% of the initial investment in just 5 years.
Step-by-step explanation:
Use the formula for continuous compounding
where r stands for the (annual) interest rate, t for time in years, P for the initial principal (investment) and X is the amount after t years.
(this formula can be beautifully derived from just basic considerations, btw)
We are given t=5, and percent increase on the initial P, so we can solve for r
It will take an interest rate of 8.1% to get 150% of the initial investment in just 5 years.
Y = 2x - 3 --------- (1)
y = 4x + 1--------- (2)
---------------------------------
Equation (2) - (1) :
---------------------------------
(y - y) = (4x + 1) - (2x - 3)
0 = 4x + 1 - 2x + 3 // remove brackets
0 = 2x + 4 // combine like terms
2x + 4 = 0 // switch sides
2x = -4 // take away 4 from both sides
x = -2 ------ sub into (1) // Divide by 2 on both sides
y = 2(-2) - 3 // Sub x = -2 into equation (1)
y = -4 - 3 // Remove bracket
y = -7 // Combine like terms
-----------------------------------
Answer: x = -2, y = -7
-----------------------------------
In the given question there is an equation that has to be solved and the value of the unknown variable "M" has to be determined. It is absolutely possible to find the exact value of the variable "M" as there is 1 equation and 1 variable.
302 + 12 M = 278
12 M = 278 - 302
12 M = - 24
M = - (24/12)
= - 2
So the value of the unknown variable "M" comes out to be -2. I hope the procedure is clear enough for you to understand and also this is the answer you were looking forward to.
It wouldn’t be 3.6ft because that’s how long the adult’s shadow is. It also couldn’t be 4ft because, it wouldn’t make sense for the child to be taller. I think 2.6ft is the best choice .
