27. Reason Adam invests $8,000 in an account that
earns 1.25% interest, compounded quarterly
for 20 years. On the same date, Jacinta invests
$8,000 in an account that earns continuous
compounded interest at a rate of 1.25% for
20 years. Who do you predict will have more
money in their account after 20 years? Explain
your reasoning.
Answers
Answer:
Jacinta will have more money
Step-by-step explanation:
For the same amount of investment and interest rate, compound interest is greater with greater number of compounds.Continuous compound is closer to daily compound which makes more compounds and returns than quarterly compound.The interest amount is provided below for quarterly and daily compound:

Answer:
1278.8 ft^3
Step-by-step explanation:
radius of cylinder = r = 5.8 ft
height of cylinder = h = 8.9 ft
radius of cone = r = 5.8 ft
height of cone = H - h = 18.5 ft - 8.9 ft = 9.6 ft
volume = volume of cylinder + volume of cone
V = (pi)(r^2)h + (1/3)(pi)(r^2)(H - h)
V = (3.14159)(5.8^2 ft^2)(8.9 ft) + (1/3)(3.14159)(5.8^2 ft^2)(9.6 ft)
V = 1278.8 ft^3
Answer:
If you use 3.14 for pi
1278.1 ft^2
Using the pi button on the calculator
1278.8 ft^2
Step-by-step explanation:
First find the volume of the cylinder
V = pi r^2 h where r is the radius and h is the height of the cylinder
V = pi ( 5.8) ^2 ( 8.9)
V = pi *33.64 * 8.9
V = 299.396 pi
The find the volume of the cone
V= 1/3 pi r^2h
The height of the cone is 18.5- 8.9 =9.6
V= 1/3 ( pi ) ( 5.8)^2 ( 9.6)
V= 1/3 ( pi ) 33.64 ( 9.6)
V = 107.648 pi
Add the two volumes together
299.396 pi + 107.648 pi
407.044 pi

Let X be a binomial random variable with p=0.3 and n=15. What is P(X=5)?
Answers
Answer:
0.20613038098
Step-by-step explanation:
The formula for Binomial Probability =
P(X) =[ n!/(n - x)! × x! ] × p^x × q^n - x
From the question
x = 5
n = 15
p = 0.3
q = 1 - p
= 1 - 0.3 = 0.7
P(x = 5) = [15!/(15 - 5)! × 5! ] × 0.3^5 × 0.7^15 - 5
P(x = 5) = 3,003 × 0.3^5 × 0.7^10
P(x = 5) = 0.20613038098
Therefore, P(x = 5) = 0.20613038098

prove cos x / 1+sinx = tan ( π\4 - x/2)
Answers
Answer:
[tex]\displaystyle \frac{\cos x}{1 + \sin x} = \tan\left(\frac{\pi}{4} - \frac{x}{2}\right)[/tex].
Overview of the steps:
Apply the double-angle identity of sines and cosines to the left-hand side of the equation.Apply the Pythagorean identity to the left-hand side of the equation.Apply the angle sum and difference identity of sines and cosine to the right-hand side of the equation.Step-by-step explanation:
Double-angle identity of sines and cosines:
[tex]\cos (2\,\alpha) = \cos^2\alpha - \sin^2\alpha = (\cos\alpha + \sin\alpha)\, (\cos\alpha - \sin\alpha)[/tex].[tex]\sin(2\,\alpha) = 2\, \sin\alpha\, \cos\alpha[/tex].Pythagorean identity for the sine and cosine of the same angle:
[tex]1 = \cos^2\alpha + \sin^2\alpha[/tex].
Angle sum and difference identity of sines and cosines:
[tex]\sin(\alpha - \beta) = \sin\alpha\, \cos\beta - \cos\alpha \, \sin\beta[/tex].
[tex]\cos(\alpha - \beta) = \cos\alpha\, \cos\beta + \sin\alpha \, \sin\beta[/tex].
Consider [tex]x[/tex] as the sum of two angles of size [tex](x/2)[/tex]. Start by applying the double-angle identity to the left-hand side.
[tex]\begin{aligned} \text{L.H.S.}&= \frac{\cos(x)}{1 + \sin(x)} \\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{1 + 2\, \sin(x / 2)\, \cos(x / 2)}\end{aligned}[/tex].
Apply the Pythagorean identity to rewrite the "1" in the denominator as [tex]\left(\cos^2(x / 2) + \sin^2(x / 2)\right)[/tex].
[tex]\begin{aligned} \text{L.H.S.}&= \frac{\cos(x)}{1 + \sin(x)} \\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{1 + 2\, \sin(x / 2)\, \cos(x / 2)}\\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{\sin^2(x/2) + 2\,\sin(x/2)\, \cos(x/2) + \cos^2 (x/2)}\end{aligned}[/tex].
Note that the denominator is now a perfect square. On the other hand, the numerator is in the form [tex](x^2 - y^2)[/tex], which is equal to [tex](x + y)\, (x - y)[/tex]. Rewrite and simplify this expression:
[tex]\begin{aligned} \text{L.H.S.}&= \frac{\cos(x)}{1 + \sin(x)} \\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{1 + 2\, \sin(x / 2)\, \cos(x / 2)}\\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{\sin^2(x/2) + 2\,\sin(x/2)\, \cos(x/2) + \cos^2 (x/2)} \\[1em] &= \frac{(\cos(x/2) + \sin(x/2))\, (\cos(x/2) - \sin(x/2))}{\left(\sin(x/2) + \cos(x/2)\right)^2} \\ &= \frac{\cos(x/2) - \sin(x/2)}{\sin(x/2) + \cos(x/2)}\end{aligned}[/tex].
The tangent of an angle is equal to the ratio between its sine and its cosine. Apply the angle sum and difference identity of sine and cosine to the right-hand side.
Note, that the sine and cosine of [tex](\pi/4)[/tex] are both equal to [tex]\left(\sqrt{2}/2\right)[/tex].
[tex]\begin{aligned}\text{R.H.S.} &= \tan\left(\frac{\pi}{4} - \frac{x}{2}\right) \\ &= \frac{\sin((\pi/4) - (x/2))}{\cos((\pi/4) - (x/2))}\\ &= \frac{\left(\sqrt{2}/2\right)\, \cos(x/2) - \left(\sqrt{2}/2\right)\, \sin(x/2)}{\left(\sqrt{2}/2\right)\, \cos(x/2) + \left(\sqrt{2}/2\right)\, \sin(x/2)} \\ &= \frac{\cos(x/2) - \sin(x/2)}{\cos(x/2) + \sin(x/2)}\end{aligned}[/tex].
Therefore:
[tex]\displaystyle \text{L.H.S.} = \frac{\cos(x/2) - \sin(x/2)}{\sin(x/2) + \cos(x/2)} =\text{R.H.S.}[/tex].
[tex]\displaystyle \frac{\cos x}{1 + \sin x} = \tan\left(\frac{\pi}{4} - \frac{x}{2}\right)[/tex].
Rewrite the given inequality as two linear inequalities. ∣8x+9∣<4
Answers
Answer:
[tex]8x+9<4[/tex] and [tex]8x+9>-4[/tex].
Step-by-step explanation:
The given inequality is
[tex]|8x+9|<4[/tex]
We need to rewrite the given inequality as two linear inequalities.
We know that |8x+9|>0 but (8x+9) can be positive or negative.
For [tex]|8x+9|<4[/tex], the value of (8x+9) must be lies between -4 and 4.
i.e., [tex]-4<8x+9<4[/tex]
If 8x+9 positive, then
[tex]8x+9<4[/tex] ...(1)
If 8x+9 negative, then
[tex]8x+9>-4[/tex] ...(2)
Therefore, the two inequalities are [tex]8x+9<4[/tex] and [tex]8x+9>-4[/tex].

Best of Luck!
Answer:
384
Step-by-step explanation:
[tex]3[(8-4)^5][/tex]÷[tex]8[/tex]
Using the rules of PEMDAS I know that I have to do the math inside of the parenthesis first.
8 - 4 = 4
Our new equation is
[tex]3[(4)^5][/tex]÷[tex]8[/tex]
Next we have to solve for the exponent.
[tex]4^5[/tex] = [tex]4*4*4*4*4[/tex] = 1,204
Our new equation looks like:
[tex]3[1024][/tex]÷[tex]8[/tex]
Now we will multiply, because we follow the rules of operation.
[tex]3 *1024= 3072[/tex]
Finally we will divide 3,072 by 8.
[tex]3072/8= 384[/tex]
Our final answer is:

A college library has five copies of a certain text on reserve. Three copies (1, 2, and 3) are first printings, and the remaining two (4, and 5) are second printings. A student examines these books in random order, stopping only when a second printing has been selected. One possible outcome is 4, and another is 214. (a) List the outcomes in S. (b) Let A denote the event that exactly one book must be examined. What outcomes are in A
Answers
Answer:
S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }
A ={(4), (5)}
Step-by-step explanation:
Given that:
Among the three copies, (1,2,3) are the first printings, and (4,5) are the second printings.
A student who examines these books in random order stops when a second printing has been selected.
Thus, we can compute the sample space associated with these experiments as:
S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }
Suppose A represents the event that we must examine exactly one book.
Then the outcomes of A are:
A ={(4), (5)}
