To determine the number of smartphones sold in 2012 with the exponential function.
What is exponential function ?
An exponential function is a mathematical function in which the variable, or the input, is in the exponent (power) of the function. It takes the form of f(x) = ab^x, where a and b are constants and x is the variable. The variable x is often time and the constant b is often greater than 1, which causes the function to grow at an increasing rate. It is often used to model growth and decay phenomena, such as population growth, radioactive decay, and others.
To estimate the number of smartphones sold in 2012, we would need to find the exponential function that models the worldwide sales of the smartphone brand from 2008 to 2011. Once we have this function, we can plug in the year 2012 as the input to estimate the number of smartphones sold in that year. However, without more information it is impossible to know the exact exponential function and the exact number of smartphones sold in 2012.

cakes in 3 hours. Which of the following is the most reasonable estimate of how many more cakes per hour Bakery B makes than Bakery A?
Using mathematical operations, we know that Bakery B makes 209/28 more cake than Bakery A per hour.
What are mathematical operations?An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
The operation's arity is determined by the number of operands.
Scalars in MATLAB can be multiplied, divided, added to, subtracted from, multiplied by, and have exponents applied to them.
These operators can be used to arrange calculations involving vectors and matrices in a straightforward manner.
So, bakery A:
4 1/4 cake in 4 hours.
16+1/4
17/4 cake in 4 hours
Bakery B:
11 5/7 cake in 3 hours:
77*5/7
82/7 cake in 3 hours
Then, Bakery A: 17/4 * 7/7 = 119/28
Bakery B: 82/7 * 4/4 = 328/28
More, cake by Bakery B:
328/28 - 119/28

Type the correct answer in the box. Round your answer to the nearest whole number. Andrew deposited $500 in a savings account that offers an interest rate of 6.5% , compounded continuously. Andrew's initial deposit will grow to about $543 in_____months.
Andrew's initial deposit will grow to about $543 in 7 months.
You can use the formula A = P * e^(rt) to calculate this, where A is the final amount, P is the initial deposit, r is the interest rate, and t is the time in years. The equation for "continual" growth (or decay) is A = Pert, where "A", is the ending amount, "P" is the beginning amount (principal, in the case of money), "r" is the growth or decay rate (expressed as a decimal), and "t" is the time (in whatever unit was used on the growth/decay rate).
A = P * e^(rt)
Plug in the given values:
A = $543
P = $500
r = 0.065 (6.5% expressed as decimal)
Solving for t:
t = ln(A/P) / r
t = ln(543/500) / 0.065
t = 0.07 ( 7 months)\
Therefore, Andrew's initial deposit will grow to about $543 in 7 months.

how many ways are there for $8$ people to sit around a circular table if none of alice, bob, and eve (three of the $8$ people) want to sit next to each other? two seatings are considered the same if one is a rotation of the other.
There are 7!/3! ways for 8 people to sit around a circular table if Alice, Bob, and Eve do not want to sit next to each other.
What is rotation?Rotation is the process of rotating an object in two or three dimensions around an axis. This axis can be a point in space, a line, or a plane. Rotation can also refer to a continuous change of direction, such as the rotation of the Earth around its axis. Rotation can be described using terms such as clockwise, counterclockwise, and angular velocity. Rotation can also be described using mathematical equations, such as Euler's rotation theorem. Rotation can be used to create symmetry in design, or to create motion in an animation.
This is because we can pick any of the 7 people to be seated first, then any of the 6 people to be seated second, then any of the 5 people to be seated third, and so on. However, since Alice, Bob, and Eve do not want to sit next to each other, we must divide the 7! by 3! to account for the fact that the order in which Alice, Bob, and Eve are seated does not matter. The 3! accounts for the fact that we could arrange the three of them in 3! = 6 different orders. Therefore, the total number of ways for 8 people to sit around a circular table if Alice, Bob, and Eve do not want to sit next to each other is 7!/(3!) = 840 ways.

The student receives 84% overall which is between 80-90% and they will receive a letter grade of "B".
To determine the student's letter grade, you need to calculate the overall percentage of the total points possible.
A percentage is a way of expressing a number as a fraction of 100. It is often used to express a proportion or a rate, and is typically denoted by the symbol "%". To convert a number to a percentage, you multiply it by 100 and add the "%" symbol.
The first exam is out of 100 points, so the student scored 89/100 or 0.89 * 100 = 89%.
The second exam is out of 100 points, so the student scored 81/100 or 0.81 * 100 = 81%.
The final exam is out of 200 points, so the student scored 160/200 or 0.8 * 100 = 80%.
To find the overall percentage of the total points possible, you need to add the percentage scores from each exam and divide by the number of exams.
(89 + 81 + 80) / 3 = 84
Therefore,The student receives 84% overall which is between 80-90% and they will receive a letter grade of "B"

The setup cost for printing the math workbooks, given the printed cost of the books, is $ 1, 800
How to find the setup cost ?The setup cost for printing the math workbooks is a fixed cost which means that it will not change regardless of the number of books that are printed.
Since we know that 1, 000 books are printed to be $ 14, 300 and that 5, 000 books cost $ 64, 300, we can find the cost of the books without the setup cost to be :
= Difference in cost of books / ( Difference in number of books )
= ( 64, 300 - 14, 300 ) / ( 5, 000 - 1, 000 )
= 50, 000 / 4, 000
= $ 12. 50

If the eggs in a basket are removed six at a time, five eggs will remain. If the eggs are removed five at a time, only four will remain. If the eggs are removed four, three, or two at a time, then three, two, and one egg will remain, respectively. But if the eggs are taken out seven at a time, no eggs will be left over. What is the least number of eggs that could be in the basket?
Answer:
119 eggs
Step-by-step explanation:
To start off, we know that this number has to be of some multiple of 7. Because if the eggs are taken out 7 at a time, and no eggs are left over, then the total number of eggs can be divisible by 7. Because there is however a multiple if you take out the eggs 2-6 times, there are eggs left over. The smallest multiple of 7 we can test is simply 7. To check, we can start with dividing 7 by 6 and getting a remainder of 1 instead of 5. So we know that 7x1 doesn't work.
The next smallest multiple of 7 that isn't multiplied from 2-6 is 7x7 to get 49. from here we can check that 49/6 = 8 r1 (r meaning remainder). So we know that 7x7 can't work. From here, the next smallest number would be 7x11.
7x11 = 77. 77/6 is 12 r5. This so far looks good. Now we can try 5. 77/5 = 15 r2. This doesn't work, so we try the next largest number which is 7x13 which is 91.
91/6 = 15 r1 which doesn't work. Next we try 7x17 which is 119. 119/6 is 19 r5 (looks good), 119/5 = 23 r4 (looks good), 119/4 is 29 r3, 119/3 is 39 r2, and 119/2 is 59 r1! Which means our answer is that the least number of eggs in the basket is 119.

The distance is 3.21 +/- 0.04 mm using the first three measurements, and 3.16 +/- 0.08 mm using the entire set of ten measurements.
What is deviation ?
Deviation is a measure of how much a set of values differs from a certain value, typically the mean (average) of the set. There are two types of deviation ,
The absolute deviation is the difference between each value and the mean.
The standard deviation is the square root of the average of the squared absolute deviations.
The mean distance = (3.27 + 3.23 + 3.15) / 3 = 3.21 mm
The standard deviation = sqrt(((3.27 - 3.21)^2 + (3.23 - 3.21)^2 + (3.15 - 3.21)^2) / 2) = 0.04 mm
So, using the first three measurements, we can report the distance as 3.21 +/- 0.04 mm
To report the distance and uncertainty using the entire set of ten measurements, we can calculate the mean and standard deviation of the ten measurements.
The mean distance = (3.27 + 3.23 + 3.15 + 3.16 + 3.28 + 3.14 + 3.16 + 3.12 + 3.32 + 1.46) / 10 = 3.16 mm
The standard deviation = sqrt(((3.27 - 3.16)^2 + (3.23 - 3.16)^2 + (3.15 - 3.16)^2 + (3.16 - 3.16)^2 + (3.28 - 3.16)^2 + (3.14 - 3.16)^2 + (3.16 - 3.16)^2 + (3.12 - 3.16)^2 + (3.32 - 3.16)^2 + (1.46 - 3.16)^2) / 9) = 0.08 mm.
The distance is 3.21 +/- 0.04 mm using the first three measurements, and 3.16 +/- 0.08 mm using the entire set of ten measurements.

The functions f(x) = -(x + 4)2+2 and g(x) = (x - 2)2-2 have been rewritten using the completing-the-square method. Apply your knowledge of
functions in vertex form to determine if the vertex for each function is a minimum or a maximum and explain your reasoning

ΩΣ
For a quadratic function [tex]y=ax^2+bx+c[/tex], we know the vertex of the graph is a maximum if and only if [tex]a < 0[/tex], and a minimum if and only if [tex]a > 0[/tex].
It is easy to see that for a function of the form [tex]y=a(x-h)^2+k[/tex], the vertex of the graph is a maximum if and only if [tex]a < 0[/tex], and a minimum if and only if [tex]a > 0[/tex].
Therefore, the vertex of the graph of [tex]f(x)[/tex] is a maximum, and the vertex of the graph of [tex]g(x)[/tex] is a minimum.
The function f(x) = -2(x + 4)+2 is minimum point and g(x) = 2(x - 2)-2 is maximum point.
What is Function?In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
We have,
f(x) = -2(x + 4)+2 and g(x) = 2(x - 2)-2
As, the equation are in the form
y = a (x-h) + k
For 1st function: f(x) = -(x + 4)²+2
f(x) = -2(x+4) + 2
So, the vertex is (4, 2) and a = -2 < 0 which is minimum point.
Now, g(x) = 2(x - 2)-2
So, the vertex is (-2, -2) and a = 2 > 0 which is maximum point.
