Find the average rate of change of each function on the interval specified.
ExtremeBDS [4]

The average rate of change (AROC) of a function f(x) on an interval [a, b] is equal to the slope of the secant line to the graph of f(x) that passes through (a, f(a)) and (b, f(b)), a.k.a. the difference quotient given by

f_{\mathrm{AROC}[a,b]} = \dfrac{f(b)-f(a)}{b-a}

So for f(x) = x² on [1, 5], the AROC of f is

f_{\mathrm{AROC}[1,5]} = \dfrac{5^2-1^2}{5-1} = \dfrac{24}4 = \boxed{6}

A shirt is originally priced at $24.50. The shirt goes on sale for 30% the original price. How much money, in dollars to the nea
ludmilkaskok [199]

Answer:

The final cost is 1.07($17.15) = $18.35

Step-by-step explanation:

If the discount is 30%, we can find the discounted price by taking 70% of the original price (since 100% - 30% = 70%).  Substitute the equivalent 0.70 to calculate the discount price:  0.70($24.50) = $17.15.  This is the discounted price.

The final cost is $17.15 times 1.07, which includes the discounted price plus the 7% tax.  That final cost is 1.07($17.15) = $18.35.

Which of the following statements is true?. . A.A tangent is never a secant.. B.A secant is always a chord.. C.A chord is always
skelet666 [1.2K]

The <em>correct answer</em> is:

A) A tangent is never a secant.

Explanation:

A tangent is a line that touches a circle in exactly one point. A secant is a line that touches a circle in two different points.

Since a tangent only touches once and a secant touches twice, there is no way a tangent can be a secant.
