Answer:

calculates the slope of a line or a curve on a given range. It is defined as the ratio of the difference in the function f(x) as it changes from 'a' to 'b' to the difference between 'a' and 'b'. The average rate of change is denoted as A(x)

Step-by-step explanation:

The average rate of change is constant for a linear function. Another way to state this is that the average rate of change remains the same for the entire domain of a linear function. If the linear function is y=7x+12 then the average rate of change is 7 over any interval selected. y=mx+b , where m is the slope.

What are the determinants for solving this linear system? 5x + 3y = 17 −8x − 3y = 9 |A| = |Ax| = |Ay| =

valentina_108 [34]

For this case we have the following system of equations:

$5x + 3y = 17\\-8x - 3y = 9$

We can Rewrite the system of equations of the form:

$Ax = b$

Where,

A: coefficient matrix

x: incognita vector

b: vector solution

We have then:

$A=\left[\begin{array}{ccc}5&3\\-8&-3\end{array}\right]$

$x=\left[\begin{array}{ccc}x\\y\end{array}\right]$

$b=\left[\begin{array}{ccc}17\\9\end{array}\right]$

Then, the determinant of matrix A is given by:

$|A|=(5)(-3)-(3)(-8)\\$

$|A|=-15+24$

$|A|=9$

Answer:

The determinants for solving this linear system are:

$|A|=9$

Subtract polynomials (intro)

ELEN [110]

Answer:

The result in standard form is:

$\left(-5t+4t^2-t\right)-\left(8t^2+t\right)=-4t^2-7t$

Step-by-step explanation:

Given the polynomials

-5t+ 4t² – t

8t² + t

subtracting 8t² + t from -5t+ 4t² – t.

$\left(-5t+\:4t^2\:-\:t\right)\:-\:\left(8t^2\:+\:t\right)$

Remove parenthese: (-a) = -a

i.e. - (8t² + t) = 8t² - t

so the expression becomes

$=-5t+4t^2-t-8t^2-t$

grouping the like terms

$=4t^2-8t^2-5t-t-t$

Add similar elements: 4t² - 8t² = -4t²

$=-4t^2-5t-t-t$

Add similar elements: -5t - t - t = -7t

$=-4t^2-7t$

Therefore, the result in standard form is:

$\left(-5t+4t^2-t\right)-\left(8t^2+t\right)=-4t^2-7t$

QF Q5.) Estimate the age of the paintings.

nikdorinn [45]

A=A₀ $e^{0.000121t}$
A/A₀=24%=0.24
0.24= $e^{0.000121t}$
0.000121t=ln(0.24)
t=ln(0.24)/0.000121
=-11794.35
so painting is 11794 years old
