Answer:
The scale factor used is 0.4
Step-by-step explanation:
Given


Required
Determine the scale factor of RST
The question can be solved using scale factor formula
Scale factor is calculated as thus;

In this case; R' is the new length and R is the old length

Substitute the values of R and R'

Factorize the denominator



<em>Hence, the scale factor used is 0.4</em>
Answer:
PV = 1414.213562
Step-by-step explanation:
Find:
PV = 8,000*V^(t+3)
Solution:
- Split the the exponent of V into t and 3:
PV = 8,000*V^t*V^3
- We will calculate the V^t and V^3 from information given.
- The present value of 10,000 at the end of 6 years and immediate value of $5,000. De-crypt this statement we have:
10,000*V^6 = 5,000
V^6 = 5,000/10,000
V^6 = 0.5
V^3 = sqrt(0.5)
- Using 2 and 3, De-crypt:
6000*V^t + 56,000*V^2t = 5000
Solving the quadratic in V^t:
V^t = 0.25
- Hence, we have the present value as:
PV = 8,000*V^t*V^3
PV = 8,000*sqrt(0.5)*0.25
PV = 1414.213562
