On the first day it was posted online, a music video got 250 views. The number of views that the video got each day increased by 16% per day. How many total views did the video get over the course of the first 12 days, to the nearest whole number?
Using an exponential function, it is found that the video got 8,314 total views over the course of the first 12 days.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growtn rate, as a decimal.On the first day it was posted online, a music video got 250 views, and the number increased by 16% a day, hence the A(0) = 250, r = 0.16, and the equation is given by:
[tex]A(t) = 250(1.16)^t[/tex]
The total amount over the first 12 days is given by:
[tex]T = \int_{0}^{12} A(t) dt[/tex]
[tex]T = \int_{0}^{12} 250(1.16)^t dt[/tex]
[tex]T = 250\frac{(1.16)^t}{\ln{1.16}}|_{t = 0}^{t = 12}[/tex]
Applying the Fundamental Theorem of Calculus:
[tex]T = 250\frac{(1.16)^{12}}{\ln{1.16}} - 250\frac{(1.16)^0}{\ln{1.16}}[/tex]
T = 8314.
The video got 8,314 total views over the course of the first 12 days.

An investment of $100 is now valued at $149.18 the interest rate is 8% compounded continuously about how long has the money been invested
question: An investment of $100 is now valued at $149.18 the interest rate is 8% per year, compounded continuously about how long has the money been invested
Answer:
5.2 years
Step-by-step explanation:
Applying
A = P(1+R/100)ⁿ.......................... Equation 1
Where A = amount, P = principle, R = rate, n = time.
From the question,
Given: A = $149.18, P = $100, R = 8%
Substitute these values into equation 1 and solve for n
149.18 = 100(1+8/100)ⁿ
149.18/100 = (1+8/100)ⁿ
1.4918 = (1+0.08)ⁿ
1.4918 = (1.08)ⁿ
Taking the Logarithm of both side
Log(1.4918) = Log(1.08)ⁿ
Log(1.4918) = nLog(1.08)
n = Log(1.4918)/Log(1.08)
n = 0.1737/0.0334
n = 5.2 years.

Answer:
the first one. slope is 1/2 and y intercebt (b value) is positive 2.
Step-by-step explanation:
Answer:
y=1/2x+2
Step-by-step explanation:
This equation is linear because the graph is a straight line. Therefore, use the slope-intercept form y=mx+b to create the equation.
To find m (the slope), pick two points like (0,2) and (2,3). Find the change in y over the change in x: (y2-y1)/(x2-x1).
y2=3, y1=2, x2=2, x1=0
(3-2)/(2-0)= 1/2
This is the slope which means the equation is one of the first 2 options.
Next find b (the y-intercept) by finding the y value on the graph when x=0. When x=0, y=2. Therefore, b=2 and the final equation is y=1/2x+2

2. At the local park, there is an annual fair that
charges $1.50 for children and $4 for adults. On
Friday, the fair sold 220 tickets and collected
$550. How many children and how many
adults attended the fair?
Answer:
132 children and 88 adults
Step-by-step explanation:
let x represent the amount of kids and y represent the amount of adults.
since the problem says there was a total of 220 people at the fair an equation can be made
x+y=220
the problem tells that each childrens ticket was 1.5$ and each adult ticket was $4 and that a total of $550 was made that day, we can use the knowledge to make an equation:
1.5x + 4y = 550
using the equations we can make this systems of equations:
1.5x + 4y =550
x + y =220
solve the systems of equations by subracting y on both sides of th bottom equation:
x=220-y
since x is equivant to 220-y it can be substitued for x in the first equation to make this:
1.5(220-y)+4y =550
--solve for y--
y=88 - there were 88 adults
substute 88 for y in the second equation
x+88=220
--solve for x--
x=138 - there were 132 children

Number of Hours Slept: 8.5, 7,6.75,5.75, 8.75,6.25,7,7.5, 4.25
Central Tendency is the statistical measure that can be used to represent all the distribution or a dataset using a single value. The most common measures of central tendency are the mode, median, and mean.
How to determine this
Mode is the value that has the highest frequency in a given data set.
So,
8.75 the highest frequency in the data set
Mode = 8.75
Median is the middle of a sorted list of numbers when arranged in ascending order.
So,
4.25, 5.75, 6.25, 6.75, 7, 7, 7.5, 8.5, 8.75 in ascending order
Median = 7
Mean is the average or the most common value in a given set of values.
Mean = 8.5 + 7 + 6.75 + 5.75 + 8.75 + 6.25 + 7 + 7.5 + 4.25/9
Mean = 61.75/9
Mean = 6.8611
Mean = 6.86 to 2 decimal place
Range is the difference between the highest value and lowest values.
Range = Maximum value - Minimum value
Range = 8.75 - 4.25
Range = 4.5

Jonathan's mom is buying him a new PS5 for his birthday. The expression 0.07p represents the sales tax on the system price, p. Write an expression in terms of p to represent the total amount that Jonathan's mom spends on the system, including tax.
Answer:
p + 0.07p
Step-by-step explanation:
tax is a compulsory sum levied by the government on goods and services. taxes increases the price paid for products
If sales tax = 0.07p, total price paid increases by 0.07p
total price paid = price of the good + tax
total amount spent by Jonathan's mom = p + 0.07p

Which source would provide the best answer to this question: what was life like for the typical female pirate who lived between 1600 and 1800
. A history book about pirates that has at least one character about female pirates
. An article about the great-great-great grandchildren of a woman pirate
. A movie that stares an actress playing a female pirate
. a guide for little girls who wants to grow up to be pirates
Answer:
A) A history book about pirates that has at least one character about female pirates
Explanation:
A history book about pirates will probably have educated views on a female pirate's life, as it's purpose is to inform.
The article about a female pirate's three-times-great grandchildren will likely not be specific and unbiased enough to have an educated answer to our question.
A movie about a female pirate will likely be dramatized and not have adequately expert ideas on the pirate's life.
A how-to-be-a-pirate guide will not accurately portray a 1600-1800 pirate woman's life. Because it's aimed at young girls, this is not a reliable source either.
So, our best answer should be A.
Good luck ^^

A car lot has both used and new cars. If 86% of the cars on the lot are new and 45% of the cars are new and have a sunroof, find the probability of randomly choosing a car with a sunroof, given that it is a new car
Answer:
0.523
Step-by-step explanation:
Let :
New car = N
Sunroof = S
P(N) = 0.86
P(N n S) = 0.45
Recall :
P(A|B) = p(AnB) / p(B)
Therefore ;
P(S|N) = P(SnN) / p(N)
P(S|N) = 0.45 / 0.86
P(S|N) = 0.523

What is m∠BAC.
............
Answer:
37 degrees
Step-by-step explanation:
1. m∠CBA = 71+45 = 116 degrees
2. m∠CBA = m∠CDA because of the quadrilateral property of opposite sides.
3. m∠CBA + m∠CDA = 2*116 = 232.
4. Total angle measure of a quadrilateral is 360 degrees, so m∠BAD + m∠BCD = 360-232 = 128 degrees.
5. m∠BAD = m∠BCD = 128/2 = 64 degrees
6. m∠BAC = m∠BAD - m∠CAD = 64 - 27 = 37 degrees

Un Cuarto De La Suma De Dos Números Es 81 Y Un Tercio De Su Diferencia Es 54. ¿Cuáles Son Tus Números?
Answer:
Los números son 81 y 243.
Step-by-step explanation:
Un sistema de ecuaciones lineales, también conocido como sistema lineal de ecuaciones o simplemente sistema lineal, es un conjunto de ecuaciones lineales que relacionan incógnitas entre sí.
Una solución de un sistema es una asignación de valores para las incógnitas que hace verdadera cada una de las ecuaciones. Esto es, en los sistemas de ecuaciones, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.
En este caso las variables o incógnitas son los números "x" e "y".
Un tercio es la tercera parte de una cantidad y se calcula dividiendo por 3, mientras que un cuarto es la cuarta parte de una cantidad y se calcula dividiendo por 4.
Si un cuarto de la suma de dos números es 81 y un tercio de su diferencia es 54, el sistema de ecuaciones queda definido como:
[tex]\left \{ {{\frac{x+y}{4} =81} \atop {\frac{x-y}{3} =54}} \right.[/tex]
Resolviendo por el sistema de sustitución, en primer lugar se debe despejar o aislar una de las incógnitas de una de las ecuaciones. En este caso, aislando la incógnita "x" de la primer ecuación se obtiene:
x +y= 4*81
x= 324 - y
Sustituyendo la expresión obtenida en la segunda expresión:
[tex]\frac{324-y-y}{3} =54[/tex]
Resolviendo se obtiene:
324-y-y= 3*54
324 - 2*y= 162
-2*y= 162 - 324
-2*y= -162
y= (-162)÷ (-2)
y= 81
Reemplazando este valor obtenido en la expresión x= 324 - y se obtiene:
x= 324 - 81
x= 243
Los números son 81 y 243.

You roll a six-sided die. What is the probability that it is an odd number or less than four? Round your answer to the nearest thousandth.
Answer:
Probability is calculated as # of favorable outcomes / # of possible outcomes.
Our favorable outcomes are 1, 2, 3, 4, 5.
There are 6 total outcomes.
5/6 = 0.833
Answer:
.667
Step-by-step explanation:
There are 3 possibilities for an odd number. 1,3 and 5
For a number less than four, there are also 3 possibilities, 1,2 and 3 (Since it's not four or less)
Counting the uniquue numbers which are not repeated, you have 1,2,3,5 so the odds are 4/6 of rolling an odd or less than four number.
Since it's asking to round, I assume we need to convert to a decimal.
Decimal: .667
Percentage: 66.667%
Both answers are rounded to the thousandth.
