Answer:
- The investment is P = $32550
- Interest rate is r = 2% or 0.02
- Time is t = 5 years or t = 10 years
<u>Formula to use:</u>
<u>For t = 5 we get:</u>
- A = 32550*(1 + 0.02)^5 = $35937.83
<u>For t = 10 we get:</u>
- A = 32550*(1 + 0.02)^10 = $39678.27
A polygon is regular when all angles are equal and all sides are equal (otherwise it is "irregular"). This is a regular pentagon (a 5-sided polygon)
0.5 pounds = 8 ounces
There are 16 ounces in a pound, and you only need half a pound so
16/2 = 8
Answer: x = 3 and y = 1
Step-by-step explanation:
y = - x + 4 ............... equation 1
y = x - 2 ............. equation 2
Solving the linear equation by substitution method , we have :
substitute equation 2 into equation 1 , that is
x - 2 = - x + 4
Add 2 to both sides , we have
x = -x + 4 + 2
Add x to both sides , we have
2x = 6
divide through by 2
x = 3
Substitute x = 3 into equation 2 to find the value of y , we have
y = x - 2
y = 3 - 2
y = 1
Therefore : x = 3 and y = 1
So we have the equations:
y - 4x = 2 --- equation 1
5y - 2x = 1 --- equation 2
(equation 2) * 2
10y - 4x = 2 --- equation 3
(equation 2) - (equation 3)
-9y = 0 so y= 0 and thus x = -1/2
Hope that helps!
