Felipe uploaded a funny viedo of his dog. The relationship between the elapsed time in days, d , since the viedo was first uploaded and the total number of views, v , that the viedo received is modeled by v=4^1.25d . Find the number of days it took Felipe's viedo to get 1024 views.
The number of days took to get the video of Felipe 1024 views is 4.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
The relationship between the elapsed time in days, d, since the video was uploaded and the total number of views, v, that the video received is modeled by the equation,
v = 4^(1.25d)
We have to find d when v = 1024
1024 = 4^(1.25d)
We have the rule for exponents aᵇⁿ = (aᵇ)ⁿ
1024 = \((4^{1.25} )^d\)
1024 = (5.6569)^d
Taking logarithms on both sides,
㏒ (1024) = ㏒ [(5.6569)^d]
We have the exponent rule for logarithm, ㏒ (aᵇ) = b ㏒ (a)
㏒ (1024) = d ㏒ (5.6569)
d = ㏒ (1024) / ㏒ (5.6569)
d = 4
Hence it took 4 days to for Felipe's video to get 1024 views.

I need Help please!!!
Step-by-step explanation:
it seems you solved the tricky part yourself already.
just to be sure, let's do the first derivative here again.
the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...
f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =
= 3t⁴ + 18t³ + 24t² + 18t + 21
f'(t) = 12t³ + 54t² + 48t + 18
and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).
we simply put the input number (2) at every place of the input variable (t).
so,
f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =
= 426

If the area between the diagonal line of absolute equality and the Lorenz curve is greater for China than for United States, we can conclude that theA) distribution of income in China is closer to being equal than in the United States
B) distribution of the income in China is as equal as in United States
C) distribution of income in China is less equal than in the US*
D)relative distributions of income in the two countries are the same
If the area between the diagonal line of absolute equality and the Lorenz curve is greater for China than for United States, we can say that a) Distribution of income in China is less equal than in the United states.
Lorenz Curve:
In economics, the Lorentz curve is a graphical representation of the distribution of income or wealth. Developed by Max O. Lorenz in 1905 to show inequality in the distribution of wealth.
This curve plots the percentage of total income or wealth received by the bottom x% of the population, which is not always true for a finite population. Often used to describe income distribution, it shows what percentage (y%) of total income the bottom x% of households have. The X-axis shows household percentage and the Y-axis shows income percentage. It can also be used to represent the distribution of wealth. Used in this way, many economists see it as a measure of social inequality.
Distribution of Income:
Income distribution shows how a country's total GDP is distributed among its population. Economic theory and policy have long made income and its distribution a central concern. Unequal distribution of income causes economic inequality, which is a concern in almost every country in the world.
Classical economists such as Adam Smith (1723-1790), Thomas Malthus (1766-1834), and David Ricardo (1772-1823) focused on the distribution of factor income, i.e. production (land, labor, capital). . Modern economists have also addressed the issue of income distribution, but have focused more on the distribution of income between individuals and households. An important theoretical and policy concern is the balance between income inequality and economic growth, and their often inverse relationship.

Debra took out a loan for $5200 and was charged simple interest at an annual rate of 10.2%. The total interest she paid on the loan was $663. How long was the loan for in months?
The principal amount of the loan is $5200 with a simple interest charged on it at an annual rate of 10.2%. The amount of interest she paid on the loan is $662. The number of months she took to pay the total loan would be 15 months.
Formula used,
Interest = Principal amount × Rate of interest × Time ---- (1)
S.I.=P×R×T
Given that:
P = $5200, R= 10.2% , S.I.= $663
On putting the values in equation (1) we get,
663 = 5200 ×0.102×T
Simplifying the above equation, we obtain,
663= 530.4× T
T = 663÷530.4
T= 1.25 years
For time taken in months, we have to multiply the time by 12 months :
T = 1.25×12
T= 15 months
Time= 15 months
Hence, the loan was taken for a period of 15 months.

Which ordered pair maximizes the objective function p=3x+8y
(0,0)
(2,7)
(5,6)
(8,1)
Answer:
P(5,6) = 63
Step-by-step explanation:
Test each point to see which ordered pair maximizes the objective function:
(0,0): p = 3(0) + 8(0) = 0
(2,7): p = 3(2) + 8(7) = 6 + 56 = 62
(5,6): p = 3(5) + 8(6) = 15 + 48 = 63
(8,1): p = 3(8) + 8(1) = 24 + 8 = 32
Hence, (5,6) is the ordered pair that maximizes the objective function.

what is function?Mathematicians research numbers and their variants, equation and related structures, objects and their locations, and prospective locations for these things. The term "module" is used to describe the connection that exists in between set of inputs, each of which has a corresponding output. A function is an input-output connection in which each inputs results in something like a single, distinct return. A domain, codomain, or scope is assigned to each function. Functions are usually denoted by the letter f. (x). An x is used for entry. On capabilities, one-to-one capabilities, multiple prowess, in capabilities, and on capabilities are the four major types of accessible functions.
The specified function appears to have a typo. I believe it should be:
\(h = -16t^2 + 38t + 5\)
a) The discus's initial height can be calculated by entering t = 0 into the function:
\(h = -16(0)^2 + 38(0) + 5 = 5\)
As a result, the discus's starting height is 5 feet.
\(-16t^2 + 38t + 5 = 0\)
\(t = (-b \sqrt(b2 - 4ac)) /\)
t = 0.003 or 2.375

Consider the following system with parameters h and k -x - 3y + 4z = -6 - 4x – 8y - 3z = 3 -11x – 7y + hz = k
Performing elementary row operations, the augmented matrix of the system can be put in upper triangular form: 1 -3 4 | -6 0 -20 13 | -21 0 0 h +18 | k - 24 For what values of h and k will the system have infinitely many solutions? a. Any value of h and k = 24. b. Any value of k and h -18 c. h = -18, k = 24 d. h= -18, k = 25 e. h = -17, k = 25 f. h = -17, k = 24
For any value of k and h = -18, the system will have infinitely many solutions.
Hence, option (b) is the correct choice.
A coefficient matrix in linear algebra is a matrix made up of the coefficients of the variables in a group of linear equations. In order to solve systems of linear equations, the matrix is employed.
The system will have infinitely many solutions when the determinant of the coefficient matrix is equal to 0.
The determinant can be calculated from the upper triangular matrix as the product of the diagonal elements, which is 0 * (-20) * (h + 18) = 0.
Therefore, the system will have infinitely many solutions when h + 18 = 0,
or h = -18.
This means the answer is (b) any value of k and h = -18.

Step-by-step explanation:
step 1
100%/the total number = percent for one probability
100/5 = 20%
2 and 4 is even.
total even number * percent for one probability = total percent for even number
20% * 2 = 40%
therefore total even number is 40%
The probability is:
2/5Step-by-step explanation:
Remember the formula for probability:
\(\boxed{\!\!\boxed{\bold{Probability=\frac{Favourable~outcome}{total~outcomes}\quad}}\!\!}\)
In this case, the favourable outcome (an even number) is 2, because there are only 2 even numbers in the set.
As for the total outcomes, there are 5 of them, because we have 5 numbers total.
So the probability of choosing an even number is 2/5.

Answer:
− √ ( 9 + y ) 2 > 1
Explanation:
− √ ( 9 + y ) 2 , where y < − 10
Simplify the expression,
− √ ( 9 + y ) 2 = − ( 9 + y ) = − 9 − y
When y < − 10 , − y > 10
Subtract 9 from both sides,
− 9 − y > 1 Hence,
− √ ( 9 + y ) 2 > 1
The value of the expression -√(9 + y)² is -9 which is more than -10. So, it is incorrect.
