Taylor plans to use $2100 to open a savings account with an annual interest rate of 1.85%. How much more interest will he earn o
Ymorist [56]
Taylor will earn $21 more in compounded interest than in simple interest.

Given:
Principal = 2100
interest rate = 1.85%
term = 8 years

Simple Interest = Principal * interest rate * term
 = 2100 * 1.85% * 8
 = 310.80

Compounded Interest = Principal * (1+r)^t
= 2100 * 1.0185⁸
= 2100 * 1.158
= 2431.80

Interest from Compounded Interest : 2431.80 - 2100 = 331.80

Simple Interest = 310.80
Compounded Interest = 331.80

331.80 - 310.80 = 21

Solve for x. Show your work.<br><br> - x &lt; -12
Andrej [43]
All you have to do is move -x to the right side and -12 to the left side to remove the negative sign.
-x<-12 (Original)
0<-12+x (Add x to both sides)
12<x (Add 12 to both sides)
The answer is 12<x, or you can write it as x>12.

1. In the diagram, AA'B'C' is an image of AABC. Which rule describes this translation?
Shtirlitz [24]

Option B: (x, y) \rightarrow(x+5, y+3) is the rule for the translation

Explanation:

The coordinates of A,B,C are (-3,2) ,(-3,-3) , (0,-2)

The coordinates of A',B',C' are (2,5) , (2,0) , (5,1)

We need to determine the rule for the translation

The rule for the translation is given by

P(x, y) \rightarrow P^{\prime}(x+a, y+b)

Let us determine the translation from A to A'

A(-3,2)\rightarrow A^{\prime}(-3+a, 2+b)\rightarrow A'(2,5)

Thus, we have,

\begin{aligned}-3+a &=2 \\a &=5\end{aligned}   and   \begin{array}{r}2+b=5 \\b=3\end{array}

Thus, the rule is given by

(x, y) \rightarrow(x+5, y+3)

Therefore, Option B is the correct answer.
