The formula of a continuous compound interest is
A=p e^rt
A future value 7300
P present value 1500
E constant
R interest rate 0.0675
T time?
Solve the formula for t
T=[log (A/p)÷log (e)]÷r
T=(log(7,300÷1,500)÷log(e))÷0.0675
T=23 years

The triangle on the grid will be translated two units left. On a coordinate plane, triangle A B C has points (negative 1, negati
nignag [31]

Answer:

Option B.

Step-by-step explanation:

The given vertices of triangle ABC are (-1, -1), (-1, -5) and (0.5, -5).

We need to find the coordinates of triangle when it is translated two units left.

So, the rule of translation is

(x,y)\rightarrow (x-2,y)

Using this rule, we get

A(-1,-1)\rightarrow A'(-1-2,-1)=A'(-3,-1)

B(-1,-5)\rightarrow B'(-1-2,-5)=B'(-3,-5)

C(0.5,-5)\rightarrow C'(0.5-2,-5)=C'(-1.5,-5)

The vertices of triangle A'B'C' are A'(-3,-1), B'(-3,-5) and C'(-1.5,-5).

Therefore, the correct option is B.
