Question 1: What is the annual percentage rate of decrease?
Answer 1: 13.5%
Question 2: What is the stock worth after 1 year?
Answer 2: 433 dollars
------------------------------------------------------
Explanation:
I'm assuming the given function is supposed to read A(t) = 500(0.988)^(12t)
If t = 0, then,
A(t) = 500(0.988)^(12t)
A(0) = 500(0.988)^(12*0)
A(0) = 500
If t = 1, then,
A(t) = 500(0.988)^(12t)
A(1) = 500(0.988)^(12*1)
A(1) = 432.566954987969
A(1) = 432.57 <<---- rounding to the nearest penny
Now compute the percent change:
100*(A(1)-A(0))/(A(0)) = 100*(432.57-500)/500 = -13.486
Note: the negative percent change means percent decrease. If the stock were increasing in value, then the percent change would be positive.
The annual percent decrease is roughly 13.486% which further rounds to 13.5%
That takes care of the first part.
To answer the second part, simply round the result for A(1) to the nearest whole number.
So round 432.57 to 433 and that's the answer to the second part.
I got this same question and I think it is (7,9)
Answer:
£27
Step-by-step explanation:
From the above question, we know that:
The price of a shirt is usually = £45. During a sale the prices in the shop are reduced by 2/5 .
Hence, the amount that the cost of tht shirt is reduced by is :
£45 × 2/5
= £18
The cost of this shirt in the sale is calculated as:
£45 - £18
= £27
Answer:
X=7 X=-1
Step-by-step explanation:
4(x^2 -6x -7) you saw that the common denominator was 4 so you divided everything by it.
(X-7)(X+1) Two numbers that multiplied give-7 and added -6 are those
X=7 X=1 equating those parenthesis to 0 gives you that
Answer:
26 degrees
Step-by-step explanation:
2 angles must equal to 180 of they share the same side/line so,
180-154=26
