Let f(x)=x2−3x−4 . What is the average rate of change from x = 7 to x = 10? Question 6 options: 24 14 66 42

1 answer:

8 0

Just find the slope between the points

basically find (f(10)-f(7))/(10-7)

f(7)=7^2-3(7)-4=49-21-4=24
f(10)=10^2-3(10)-4=100-30-4=66

slope=(66-24)/(10-7)=42/3=14
average rate of change is 14

Answer:

A. If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points

B. From the graph, it is clear that the initial value of the graph is 60 m and it represents the initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.

The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min.

Which conjunction about whole numbers is true?

alexandr402 [8]

Answer:

The sum of two even numbers is even and greater than the addends.

Step-by-step explanation:

Let 2n and 2m be two even numbers.

The sum of these numbers is

$2n+2m$

Use distributive property:

$2(n+m)$

This number is even because 2 is its factor.

Note that

$2n+2m>2n\\ \\2n+2m>2m$

Thus, correct option is:

The sum of two even numbers is even and greater than the addends.

The zero of F -1(x) in F(x) = x + 3 is<br><br> -3<br> 0<br> 3

Effectus [21]

Answer:

The only zero of $F^{-1}(x)$ is $3$ .

Step-by-step explanation:

The function $F^{-1}$ is the inverse of function $F$ .

For a given $x$ and a given $y$ , $F^{-1}(y) = x$ if and only if $F(x) = y$ .

Let $y$ be a zero of $F^{-1}(y)$ . That is, $F^{-1}(y) = 0$ .

By the reasoning above, since $x = 0$ and this particular $y$ satisfy $F^{-1}(y) = x$ , it must be true that $F(x) = y$ for the same $x = 0\!$ and $y\!$ .

Since $x = 0$ and $F(x) = x + 3$ , $F(0) = 3$ . Therefore, $y = F(0) = 3$ since $y = F(x)$ .

Thus, the zero of $F^{-1}(y)$ would be $y = 3$ .
