Myra invested $10,000 in an account earning a nominal 8% per year compounded continuously. How much was in the account at the end of one year? Round the answer to nearest dollar.
Answer:
[tex]\$10,833[/tex]
Step-by-step explanation:
we know that
The formula to calculate continuously compounded interest is equal to
[tex]A=P(e)^{rt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
e is the mathematical constant number
we have
[tex]t=1\ years\\ P=\$10,000\\ r=0.08[/tex]
substitute in the formula above
[tex]A=\$10,000(e)^{0.08*1}=\$10,833[/tex]
Compound interest computed continuously after one year on a principal sum of $10,000 with an 8% interest rate will yield $10,833, rounded to the nearest dollar.
Explanation:Your question relates to the mathematics topic of compound interest. When interest is compounded continuously, we use the formula A = P * e^(rt), where A is the amount of money accumulated after n years, including interest. P is the principal amount (the initial amount of money), r is the annual interest rate (in decimal form), and t is the time in years.
In your case, you are looking to find how much $10,000, invested at a nominal 8% per year compounded continuously, would amount to at the end of one year. Substituting the given values into the formula, we have:
A = $10,000 * e^(0.08*1).
The value of 'e' is approximately 2.71828. Therefore, we calculate:
A = $10,000 * 2.71828^0.08 = $10,833.
So, the amount in the account at the end of one year, rounded to the nearest dollar, would be $10,833.

Write ln 2x + 2x ln x -ln 3y as a single logarithm.
Answer: option c.
Step-by-step explanation:
To solve this problem you must keep on mind the properties of logarithms:
[tex]ln(b)-ln(a)=ln(\frac{b}{a})\\\\ln(b)+ln(a)=ln(ba)\\\\a*ln(b)=ln(b)^a[/tex]
Therefore, knowing the properties, you can write the expression gven in the problem as shown below:
[tex]ln2x+2lnx-ln3y=ln2x+lnx^2-ln3y\\\\=ln(2x)(x^2)-ln3y\\\\=ln(\frac{2x^3}{3y})[/tex]
Therefore, the answer is the option c.
Answer:
C
Step-by-step explanation:
We can use 3 properties here to write this as single logarithm:
1. Log (a^b) = b Log a
2. Log x + Log y = Log (x*y)
3. Log x - Log y = Log (x/y)
We can use property #1 first to write:
[tex]ln2x+2lnx-ln3y\\=ln2x+lnx^2-ln3y[/tex]
Now we can use property #2 and property #3 to write this as single logarithm:
[tex]ln2x+lnx^2-ln3y\\=ln(\frac{(2x)(x^2)}{3y})\\=ln(\frac{2x^3}{3y})[/tex]

The scores on a standardized test are normally distributed with a mean of 500 and a standard deviation of 60. Jake scored 520 on the test. What percent of students scored below Jake? Include a step by step description of the process you used to find that percentage. (Round your answer to the nearest whole number.)
Answer:
63 percent student scored below Jake.
Step-by-step explanation:
For finding the percentile
Step 1: Subtracting mean from Jake’s score
=520-500
=20
Step 2: Calculating z-score
The z-Score is found by dividing the difference obtained in step 1 by SD of the data
z-score= 20/60
z-score=0.333
Step 3: Converting the z-score to percentile
The z-score will be converted to percentile using the z-score to percentile conversion table, the value of percentile for 0.3333 is 63rd .
So, 63 percent students scored below Jake.

(Q8) The graph of an exponential function is given. Which of the following is the correct equation of the function? (Picture Provided)
Answer:
b. [tex]y=3.9^x[/tex]
Step-by-step explanation:
Remember that the standard exponential function is [tex]y=ab^x[/tex]
where
[tex]a[/tex] is the coefficient
[tex]b[/tex] is the base
If [tex]b>0[/tex], the function is growing
If [tex]0<b<1[/tex] the graph is decaying
We can infer from the graph that the function is growing, so we can discard [tex]y=0.45^x[/tex] and [tex]y=0.73^x[/tex].
Now, to evaluate our tow remaining equations, we are using the test values [tex]x=0[/tex] and [tex]x=1[/tex]:
For [tex]y=1.8^x[/tex]
For [tex]x=0[/tex]
[tex]y=1.8^0[/tex]
[tex]y=0[/tex]
For [tex]x=1[/tex]
[tex]y=1.8^1[/tex]
[tex]y=1.8[/tex]
The graph passes through the points (0,1) and (1, 1.8)
For [tex]y=3.9^x[/tex]
[tex]x=0[/tex]
[tex]y=3.9^0[/tex]
[tex]y=0[/tex]
[tex]x=1[/tex]
[tex]y=3.9^1[/tex]
[tex]y=3.9[/tex]
The graph passes through the points (0,1) and (1, 3.9)
We can see in the graph when [tex]x=1[/tex], [tex]y[/tex] is almost 4, so we can conclude that the correct equation is [tex]y=3.9^x[/tex]

What is the equation of a line that is parallel to y=47x−3 and passes through (14, 4) ?
PARALLEL slopes always have the same slope no matter what because they are parallel
Answer:
[tex]y=47x-654[/tex]
Step-by-step explanation:
To find the line parallel to the given linear equation, we have to use the same slope, because the condition of parallelism is that they must have the same slope.
So, the slope of the given line is [tex]m=47[/tex], because it's expressed in slope-intercept form, where the coefficient of the variable x is the slope.
Now, we know that they new parallel lines must have a slope equal to 47, and must pass through (14,4). Using this data, we apply the point-slope formula to find the equation of the new line:
[tex]y-y_{1}=m(x-x_{1})\\y-4=47(x-14)\\y=47x-658+4\\y=47x-654[/tex]
The image attached shows the parallelism.
Therefore, the answer is [tex]y=47x-654[/tex]

A warehouse worker moved 108 pallets in 4.5 hours. In minutes, what is the rate to move one pallet? The worker will be off the clock in 2 hours. How many pallets can he move before quitting time?
Number of pallets moved in 4.5 hours = 108
converting 4.5 hours in minutes we get,
4*60 + 0.5*60 = 240+30 = 270 minutes
So, 108 pallets were moved in = 270 minutes
1 pallet was moved in = [tex]\frac{270}{108}=2.5[/tex] minutes
As the tie will get over in 2 hours or 2*60 = 120 minutes, the number of pallets that can be moved will be = [tex]\frac{120}{2.5}= 48[/tex] pallets.
Hence, 48 pallets can be moved before quitting time.
Answer:
The answer is 2.5 minutes; 48 pallets
Step-by-step explanation:
Number of pallets worker moved in a warehouse = 108
Number of hours it takes to do so = 4.5
Rate at which they require to move one pallet is given by
Number of pallets worker moved in a warehouse = 108
Number of hours it takes to do so = 4.5
Rate at which they require to move one pallet is given by
4.5/108 x 60 minutes = 2.5 minutes
Now, if the worker will be off the clock in 2 hours ,
So, number of pallets he can move before quitting time is given by
In 4.5 hours, number of pallets they moved = 108
In 1 hour, number of pallets they moved = 108/4.5 = 24
In 2 hours, number of pallets they moved = 24 x 2 = 48

Is an elevation of -10 feet closer or farther from the surface of the ocean than an elevation of -8 feet?
Answer:
farther
Step-by-step explanation:
The negative sign means that it is 10 feet down while -8 is only 8 feet down
An elevation of -10 feet is farther from the surface of the ocean than - 8 feet.
What is something else that can not be negative?Time can not be negative as we can not go to past.Time is unidirectional.
According to the given question we have to determine Is an elevation of -10 feet closer or farther from the surface of the ocean than an elevation of -8 feet.
We know that -10 is less than -8 as it is present in the left of -8 in the number line that is one case.
But here we are measuring elevation which is length and we know length can not be negative so going by the idea of length an elevation of -10 feet is farther from the surface of the ocean we are diving 10 feet below here so more distance.

What is the sum of the series 3,---5,-13..........-229
ANSWER
[tex]S_{30}= - 3390[/tex]
EXPLANATION
The given sequence is
3,-5,-13,.....-229.
The first term of this sequence is
a_1=3
There is a common difference of
[tex]d = - 5 - 3 = - 8[/tex]
The last term of this sequence is -229.
The nth term of this sequence is given by:
[tex]a_n=a_1+d(n-1)[/tex]
We use the last term to determine the number of terms in the sequence.
[tex] - 229 = 3 + - 8(n - 1)[/tex]
[tex]- 229 - 3= - 8(n - 1)[/tex]
[tex]- 232= - 8(n - 1)[/tex]
Divide through by -8;
[tex]29= (n - 1)[/tex]
[tex]n = 30[/tex]
Hence there are thirty terms in the sequence.
The sum of the first n terms is given by:
[tex]S_n= \frac{n}{2} ( a_{1} + l)[/tex]
The sum of the first 30 terms is given by:

AM ² = 153
AM =√153 = √(9× 17) = 3√17
sinA = MT /AT = 4/13
cosA = AM/AT = (3√17)/13
tanA = MT/AM = 4/(3√17) = (4√17)/51
sinT = AM/AT = (3√17)/13
cosT = MT/AT = 4/13
tanT = AM/MT = (3√17)/4

10² = 5² + AJ²
100 = 25 + AJ²
AJ² = 75
AJ = √75 = √(25×3) = 5√3
sinA = JT/AT = 5/10 = ½
cosA = AJ/AT = (5√3)/10 = (√3)/2
tanA = AJ /AJ = 5/(5√3) = (√3)/3
sinT = AJ/AT = (5√3)/10 = (√3)/2
cosT = AJ/AT = 5/10 = ½
tanT = AJ/JT = (5√3)/5 = √3

By the negative exponent rule, you have that:
[tex](\frac{1}{a})^n=a^{-n}[/tex]
By the exponents properties, you know that:
[tex](m^n)^l=m^{(nl)}[/tex]
[tex](m^n)(m^l)=m^{(n+l)}[/tex]

Keeping on mind the exponents properties, you have:
[tex](2)^{2(x-7)}*(2)^{3(2x-3)}=32(2^{-(x-9)}[/tex]
[tex](2)^{2(x-7)}*(2)^{3(2x-3)}=(2^5)(2^{-(x-9)})\\\\(2)^{(2x-14)}*(2)^{(6x-9)}=(2^5)(2^{(-x+9)})\\\\2^{((2x-14)+(6x-9))}=2^{(5+(-x+9))}[/tex]
