Answer:
B, I solved then used interval notion to convert it.
Equation required for this question:
an • 1.072^n = 14,580
Where a = payment every half year and n = number of half years
There are 12 half years in 6 years.
Therefore n = 12, substitute this.
12a • 1.072^12 = 14,580
12a = 14,580 / 1.072^12
12a = 6,330~
a = 527.5 ~
90 degrees for the rectangle because 360 divided by 4
Is 90 for one of them and 120 degrees for the triangle 3 divided by 360
I think the answer is the third one
The expression inside the absolute value can be either positive or negative.
above, they solved for x in the positive expression. x/2 + 3 = 2
solve for x in the negative expression.
x/2 + 3 = -2
x/2 = -2 - 3
x/2 = -5
x = -10
