Answer:

c.

Step-by-step explanation:

If its isoceles, then LM is equal to LN. This means 3x-2 = 2x+1. 3x minus 2x is x. 2 plus 1 is 3. So x = 3. So it needs to be c or d. since LM and LN are the same answers, go to MN and find the answer. If you siubstitute 3 for x in 5x-2, then you get 13.

If Jeannie invests $7,250 at a rate of 12%, compounded weekly, find the value of the investment after 10 years. $24,037.59 $16,0
Karolina [17]
Hi there!

• Principle amount, P = $ 7, 250

• Rate of interest, r = 12 %

• No. of weeks in an year, n = 52

• Time period, t = 10 years

Aₜ = P [ 1 + (\dfrac {r}{n}) ] ᴺ ˣ ᵀ

A₁₀ = 7, 250 [ 1 + (\dfrac {0.12}{52}) ] ⁵² ˣ ¹⁰

Simplifying :-

A₁₀ = $ 24,037.59

Hence,
Option [ 1. ] - $ 24,037.59 is Correct

~ Hope it helps!
