Answer:
It'll take 38.3 years to obtain the desired return of $25,000.
Step-by-step explanation:
In order to solve a continuosly coumponded interest question we need to apply the correct formula that is given bellow:
M = C*e^(r*t)
Where M is the final value, C is the initial value, r is the interest rate and t is the time at which the money was applied. Since he wants an return of $25,000 his final value must be the sum of the initial value with the desired return. So we have:
(25000 + 8000) = 8000*e^(0.037*t)
33000 = 8000*e^(0.037*t)
e^(0.037*t) = 33000/8000
e^(0.037*t) = 4.125
ln[e^(0.037*t)] = ln(4.125)
t = ln(4.125)/(0.037)
t = 1.4171/0.037 = 38.2991
t = 38.3 years
Answer:
for calculating weighted mean of 64 patients with pulmonary tuberculosisfor calculating weighted mean of 64 patients with pulmonary tuberculosis by age group in Baghdad, find the arithmetic mean of the age of these patients, where Xj fj = 1660 by age group in Baghdad, find the arithmetic mean of the age of these patients, where Xj fj = 1660
Answer: All these numbers are the cube of consecutive numbers ,the cube of 1 is 1, the cube of 2 is 8 ,3 is 27 ,4 is 64 and so the next number which is 5 , it's cube will be 125 and so the series will be 1, 8, 27, 64, 125 ,216 and so on…!
Answer:
1065
Step-by-step explanation:
A right square pyramid consist of
- 1 base area which is a square, area of square = l²
- 4 triangles, area of a triangle = 1/2 (slant height)(base)
area of 4 triangle = 2 (slant height)(base)
In question we are given perpendicular height of pyramid not the slant height so first we will calculate the slant height.
By using pythagorus:
Slant height = √(24²+8²)
= 8√10
Surface area = baseArea + 2 (slant height)(base)
= 16² + 2( 8√10)(16)
= 1065
Answer:
remainder 25
Step-by-step explanation:
if 42,325 is divided by 47the result is 25,
firstly divide 42,325 by 47, you will see that it can only divide 42,325 which is 900 without any remainder,then the 900 is the whole number and 25 is remaining from the subtraction of 42,325-42,300=25 ,and 25 has to be divided by 47 but it is not up to 47,then we have it as a remainder,
so 25 is the remainder
