A = s(1-dn)
a = s - sdn
a - s = -sdn
a - s = (-sd)n
(a-s) ÷ (-sd) = n
12(+2) B. thats the answer
<h3>
Answer: (4, -3)</h3>
==================================================
Work Shown
We'll be using these vector properties
- Rule 1: (a,b) + (c,d) = (a+c, b+d)
- Rule 2: k*(a,b) = (k*a, k*b)
To get the following
-2u + v = -2*(-1, 5) + (2,7)
-2u + v = (-2*(-1), -2*5) + (2,7) .... apply rule 2
-2u + v = (2, -10) + (2, 7)
-2u + v = (2+2, -10+7) .... use rule 1
-2u + v = (4, -3)
Answer:
Option B -
Step-by-step explanation:
Given : Fidel has a rare coin worth $550. Each decade, the coin's value increases by 10%.
To find : Which expression gives the coin's value, 6 decades from now?
Solution :
The given situation represents the exponential function,
where, a is the initial value i.e. a=$550
r is the increased rate r=10%
n is the time i.e. n=6
Substitute the value in the formula,
Therefore, option B is correct.
