William invested $6000 in an account that earns 5.5% interest, compounded annually. The formula for compound interest is A(t) = P(1 + i)t.
How much did William have in the account after 6 years? (APEX)
Answer:
William have $8273.057 in the account after 6 years.
Step-by-step explanation:
The given formula is [tex]A(t)=P(1+i)^t[/tex]
We have,
P = $6000
r = 5.5% = 0.055
t = 6
A =?
Substituting these values in the above formula to find A
[tex]A(t)=6000(1+0.055)^6\\\\A(t)=8273.057[/tex]
Therefore, William have $8273.057 in the account after 6 years.

The probability of the complement of event B, denoted as Bc, is 0.8.
Explanation:To find the probability of the complement of an event B, denoted as Bc, we can use the formula: P(Bc) = 1 - P(B). Given that events A and B are mutually exclusive, P(B) = 0.2. Therefore, P(Bc) = 1 - 0.2 = 0.8.

If f(x) is a nth degree polynomial then F^(n+1)(x)=0. True or false and why
Final Answer:
The given statement “If f(x) is a nth degree polynomial then [tex]F^{(n+1)(x)=0[/tex]. True or false and why” is false because the (n+1)st derivative being zero is contingent on the specific value of the leading coefficient in the polynomial. It is not a general rule for all nth degree polynomials.
Explanation:
The statement [tex]\(F^{{(n+1)}(x) = 0\)[/tex] is not universally true for all nth degree polynomials (f(x)). To understand why, consider a general nth degree polynomial [tex]\(f(x) = a_nx^n + a_{n-1}x^{n-1} + \ldots + a_1x + a_0\)[/tex], where [tex]\(a_n\)[/tex] is the leading coefficient and [tex]\(a_n \neq 0\)[/tex].
The nth derivative of (f(x)) can be expressed as [tex]\(f^{(n)}(x) = n! \cdot a_n\).[/tex]Now, the (n+1)st derivative, [tex]\(f^{(n+1)}(x)\)[/tex], will be zero if and only if the leading coefficient [tex]\(a_n = 0\)[/tex]. However, this condition is not satisfied in general, as [tex]\(a_n\)[/tex] is assumed to be nonzero for a nontrivial polynomial. Therefore, the (n+1)st derivative is not guaranteed to be zero for all nth degree polynomials.
In mathematical terms,[tex]\(F^{(n+1)}(x)\)[/tex] equals zero if and only if the leading coefficient of (f(x)) is zero, but this is not a universal characteristic of nth degree polynomials. Consequently, the statement is false, and the (n+1)st derivative may not be zero for all x in the domain of the polynomial.

find the binomial coefficient: 2012/2011
The binomial coefficient '2012 choose 2011' is calculated using the formula C(n,k) = n! / [(n-k)! * k!]. After substituting the respective values into the formula, we find that the binomial coefficient of '2012 choose 2011' is 2012.
Explanation:The binomial coefficient, often referred to in Mathematics, is generally expressed as 'n choose k' and calculated using the formula: C(n,k) = n! / [(n-k)! * k!]. In this formula, the '!' denotes factorial which means the product of an integer and all the integers below it.
However, the student's question seems to be asking for the binomial coefficient of '2012 choose 2011', which is misinterpreted as a fraction instead.
To calculate it correctly, we would apply the formula mentioned before: C(2012,2011) = 2012! / [(2012-2011)! * 2011!]. Because 2012-2011 equals 1, this simplifies our calculation. The factorial of 1 is 1 itself. Thus, C(2012,2011) = 2012!/ (1! * 2011!), which simplifies to be 2012. So the binomial coefficient of '2012 choose 2011' is 2012.

Every evening Jenna empties her pockets and puts her change in a jar. At the end of the week she counts her money. One week she had 38 coins all of them dimes and quarters. When she added them up she had a total of $6.95
d = dimes
q = quarters
d+q = 38 coins
q=38-d
0.25q + 0.10d=6.95
0.25(38-d)+0.10d=6.95
9.5-0.25d+0.10d=6.95
-015d=-2.55
d=-2.55/-0.15 = 17
q=38-17 =21
21*0.25 =5.25
17*0.10 = 1.70
5.25+1.70 = 6.95
she had 21 quarters and 17 dimes
Answer:
She had 17 dims and 21 quarters to make $6.95.
Step-by-step explanation:
Given : Every evening Jenna empties her pockets and puts her change in a jar. At the end of the week she counts her money. One week she had 38 coins all of them dimes and quarters.
To find : When she added them up she had a total of $6.95?
Solution :
Let d be the dims and q be the quarters.
She had 38 coins.
i.e. [tex]d+q=38[/tex] ......(1)
The value of d is 0.10 and q is 0.25.
The total she had of $6.95
i.e. [tex]0.10d+0.25q=6.95[/tex] .......(2)
Solving (1) and (2),
Substitute d from (1) into (2)
[tex]0.10(38-q)+0.25q=6.95[/tex]
[tex]0.10\times 38-0.10q+0.25q=6.95[/tex]
[tex]3.8+0.15q=6.95[/tex]
[tex]0.15q=6.95-3.8[/tex]
[tex]0.15q=3.15[/tex]
[tex]q=\frac{3.15}{0.15}[/tex]
[tex]q=21[/tex]
Substitute in equation (1),
[tex]d+21=38[/tex]
[tex]d=38-21[/tex]
[tex]d=17[/tex]
Therefore, She had 17 dims and 21 quarters to make $6.95.
An arithmetic sequence is represented in the following table. Enter the missing term of sequence
Answer:
The required 18th term of the given sequence will be -160
Step-by-step explanation:
The A.P. is given to be : 44, 28, 12, -4, ....
First term, a = 44
Common Difference, d = 28 - 44
= -12
We need to find the 18th term of the sequence.
[tex]a_n=a+(n-1)\times d\\\\\implies a_{18}=44+(18-1)\times -12\\\\\implies a_{18}=44+ 17 \times -12\\\\\implies a_{18}=44-201\\\\\implies a_{18}=-160[/tex]
Hence, The required 18th term of the given sequence will be -160

A large tank is filled to capacity with 600 gallons of pure water. brine containing 4 pounds of salt per gallon is pumped into the tank at a rate of 6 gal/min. the well-mixed solution is pumped out at the same rate. find the number a(t) of pounds of salt in the tank at time t.
To find the amount of salt in the tank at a given time, one can use the equation a(t) = Q - Qe^(-rt). In this case, Q (the quantity of salt at a steady state) equals the pump rate multiplied by the salt concentration (24lb/min), and r (the rate of inflow and outflow of the solution) is the rate at which water is pumped out divided by the volume of the tank (1/100 per min). Substituting these values into the equation gives the salt content at any given time.
Explanation:The quantity of salt in the tank at any given time can be determined by the equation of the form a(t) = Q - Qe^(-rt), in which Q is the quantity of salt that would be in the tank at a steady state (i.e., if enough time had passed that the quantity of salt in the tank stopped changing), r is the rate of inflow and outflow of the solution, and t is the time at which you're trying to determine the number of pounds of salt in the tank.
In this case, Q = rate of inflow x concentration of the inflow, which is 6 gal/min x 4 lb/gal = 24 lb/min. This amount is reached after a sufficient amount of time has passed and the tank has reached a steady state.
The rate, r, is the rate at which the water is pumped out of the tank. In this situation, that's 6 gallons per minute. Since there are 600 gallons of water in the tank at the start, r = 6 gal/min ÷ 600 gallons = 1/100 min^-1.
Therefore, the number of pounds of salt in the tank at any time t is a(t) = Q - Qe^(-rt) = 24 lb/min - 24 lb/min * e^[-(1/100 min^-1)*t].

Owners of a recreation area are filling a small pond with water. They are adding water at a rate of 35 liters per minute. There are 700 liters in the pond to start. Let W represent the total amount of water in the pond (in liters), and let T represent the total number of minutes that water has been added. Write an equation relating W to T . Then use this equation to find the total amount of water after 19 minutes.
An equation relating W to T is,
W = 700 + 35T
And, Total amount of water after 19 minutes is, 1365 liters
We have to given that,
Owners of a recreation area are filling a small pond with water. They are adding water at a rate of 35 liters per minute.
There are 700 liters in the pond to start.
Now, Let W represent the total amount of water in the pond (in liters), and let T represent the total number of minutes that water has been added.
Hence, an equation relating W to T is,
W = 700 + 35T
So, For T = 19 minutes,
W = 700 + 35 x 19
W = 700 + 665
W = 1365
Therefore, Total amount of water after 19 minutes is, 1365 liters
