What is the average rate of change of the function in the table at the interval x = -1 to x = 1?
Andre45 [30]

Answer:

the answer is undefined

Step-by-step explanation:

If a function, f(x), is continuous (that is, has values for every x in the interval) from x=- 1 to x=1 ), then the average rate of change is:( total amount that f(x) changes ) / (total amount that x changes)( f(1) - f(-1) ) / ( (1) - (-1) )( f(1) - f(-1) ) / 2The variable x changes from (-1) to (1). That value is 2. [note: (1)-(-1) ]The function changes from f(-1) to f(1). You must determine f(1)-f(-1) and use that value as the numerator.Fill in the values to determine the average rate of change: ( f(1) - f(-1) ) / 2However, if the plot of y values is not a function, and there is some x value between -1 and 1 for which f(x) is undefined, then the rate of change of y from f(-1) to f(1) is also undefined.

PLEASE ANSWER CLEARLY WITH THE EQUATION
STatiana [176]

After solving the provided question, Aisha spent 7.9 hours and 9.9 hours, respectively, working last week as a babysitter and a landscaper.

<h3>Which is an equation?</h3>

A mathematical statement that has at least two terms, both of which contain variables or equal integers, is defined as an equation.

Aisha is reportedly working two summer jobs, earning $7 an hour for babysitting and $8 an hour for gardening.

Let's say you were to watch the children for x hours.

And y would be the amount of hours spent on landscaping.

Last week, Aisha spent two more hours babysitting than a landscaper, earning a total of $134.

y = x + 2\\7x + 8y = 134\\Substitute the value of y = x + 2 in the equation,\\7x + 8(x + 2) = 134\\7x + 8x + 16 = 134\\15x = 134 - 16\\15x = 118\\x = 118/15\\x = 7.9\\Substitute the value of x = 7.9 in the equation y = x + 2 ,\\y = 7.9 + 2\\y = 9.9\\

Could anyone help with this question?
Nikitich [7]

Answer:

I just answered this question, In case you missed it, here it goes again:

Values for the coefficient in the product k:

a=b=c=d=3*10^8, so the first four boxes should be filled with the number "3"

Drop down arrow: "does"

Step-by-step explanation:

We perform all the products of wavelength time frequency indicated for the column of the quantity "k":

a=1 * 10^{-10} * 3\, * 10^{18} = 3 * 10^{-10+18} = 3 * 10^{8}=

b=1 * 10^{-1}*3*10^9=3* 10^{-1+9}=3*10^8

c=600*10^{-6}*5*10^{11}=3000*10^{-6+11}=3000*10^5=3*10^3*10^5=\\=3*10^{3+5}=3*10^8

d=4*10^{-7}*7.5*10^{14}=30.0*10^{-7+14}=30*10^7=3*10*10^7=\\=3*10^{1+7}=3*10^8

Therefore, all products of these different wavelengths and their associated frequencies render the exact same answer : 3*10^8, which means that as one of these quantities increase, the other one will decrease in the same proportion to give the same numerical answer.

This means that the two quantities are associated via inverse proportionality. As seen in the equation below, if the quantities "x" and "y" are related by inverse proportionality (shown as one equals a constant "A" divided by the other variable), their product x*y will give that constant value "A" (which in our case is 3*10^8.

x=\frac{A}{y} \\x*y=A
