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.

x is equals to 4 and y is equal to 1
Step-by-step explanation:
3x+3y=9
x-3y=7
elimination method has to do with eliminating one variable from the question to eliminate y we have to add the equations together which is 4x=16
X=4
substitute x is equal to 4 into any equation of your choice let's use equation 1
E
3(4)+3y=9
12+3y=9
12-9=3y
3=3y
divide both sides by 3 therefore y is equal to 1.

An acute triangle has sides measuring 10 cm and 16 cm. The length of the third side is unknown.
Which best describes the range of possible values for the third side of the triangle
In a rectangle, the length is 5 more than three times the width. The perimeter is 250cm. Determine the length of each side.
Answer:
l = 95 cm
w = 30 cm
Step-by-step explanation:
w = width
5+3w = length
P = 2l + 2w
250 = 2(5+3w) + 2w
250 = 10 + 6w + 2w
240 = 8w
w = 30
5 + 3(30) = length
l = 95

What is the maximum height of of Anna's golf ball? The equation is y=x−0.04x2.
Given:
The height of a golf ball is represented by the equation:
[tex]y=x-0.04x^2[/tex]
To find:
The maximum height of of Anna's golf ball.
Solution:
We have,
[tex]y=x-0.04x^2[/tex]
Differentiate with respect to x.
[tex]y'=1-0.04(2x)[/tex]
[tex]y'=1-0.08x[/tex]
For critical values, [tex]y'=0[/tex].
[tex]1-0.08x=0[/tex]
[tex]-0.08x=-1[/tex]
[tex]x=\dfrac{-1}{-0.08}[/tex]
[tex]x=12.5[/tex]
Differentiate y' with respect to x.
[tex]y''=(0)-0.08(1)[/tex]
[tex]y''=-0.08[/tex]
Since double derivative is negative, the function is maximum at [tex]x=12.5[/tex].
Substitute [tex]x=12.5[/tex] in the given equation to get the maximum height.
[tex]y=(12.5)-0.04(12.5)^2[/tex]
[tex]y=12.5-0.04(156.25)[/tex]
[tex]y=12.5-6.25[/tex]
[tex]y=6.25[/tex]
Therefore, the maximum height of of Anna's golf ball is 6.25 units.
use the matrix tool to solve the system of equations enter the answer as an ordered pair. 8x+5y=9 -x+y=7
Answer:
x = -44/13
y = -65/13
Step-by-step explanation:
Using matrix form means using the crammers rule
The matrix form of the expression is written as;
[tex]\left[\begin{array}{ccc}8&5\\-1&1\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}9\\7\\\end{array}\right][/tex]
AX = B
taking the determinant of A;
|A| = 8(1) - 5(-1)
|A| = 8 + 5
|A| = 13
After replacing the first row with the column matrix;
[tex]A_x =\left[\begin{array}{ccc}9&5\\7&-1\\\end{array}\right][/tex]
|Ax| = 9(-1)-5(7)
||Ax| = -9 - 35
|Ax| = -44
x = |Ax|/|A|
x = -44/13
similarly for y
[tex]A_x =\left[\begin{array}{ccc}8&9\\-1&7\\\end{array}\right][/tex]
|Ay| = 8(7)+9
|Ay| = 56+9
|Ay| = 65
y = |Ay|/|A|
y = -65/13
The mean weight of nine players on a baseball team is 71 pounds. The weights of the nine baseball players are: { 64, 75, 68, 72, 80, 76, 68, 74, n }. The equation below can be used to find the weight of the ninth player. Which of the values listed { 71, 73, 62, 82, 64 } can be the weight of the ninth baseball player? Explain how you found your answer.
Answer:
Step-by-step explanation
The mean is equal to the total weight of the players/the number of players
So, 64, 75, 68, 72, 80, 76, 68, 74, n/ 9=71
Once you add the values in the numerator, you would get 577+n/9=71
n= 71 * 9=639
639-577=62
So, the weight of the 9th player would be 62 pounds.

You earn $30K at your job, and put 20% aside each month into a retirement fund. Your
company is super cool and matches your contributions. For every dollar you put into
your IRA, your employer also puts in a dollar.
How much will you have contributed to your retirement account by the end of the year?
Answer:
$12,000
Step-by-step explanation:
20% as a decimal is 0.20
30,000 x 0.20 = 6,000
If the employer matches that, the amount deposited is double.
6,000 x 2 = 12,000
That is probably the answer they want. Technically the question asks way *you* will have contributed, which is $6,000, but I don’t think they’re trying to make this a trick question. I would go with 12k

Will give brainliest and 5 stars if correct. How does Shakespeare manipulate language?
Answer:
Shakespeare uses the language of the characters to achieve this multifaceted quality. Through the use of language (specifically Iago, Othello, and Desdemona), Shakespeare propels the plot, engages the audience, creates dramatic irony, and reveals the characters’ psyches.
Answer:
Shakespeare's writings greatly influenced the entire English language. He expanded the scope of English literature by introducing new words and phrases, experimenting with blank verse, and also introducing new poetic and grammatical structures.
