Perhaps, she is interested in finding the area enclosed by this triangular park.

Step-by-step explanation:

The area of the triangle enclosed by the three points

A(1,1), B(1,4) and C(-3,4) in this question will be given by

|Ax ( By  − Cy)+ Bx(Cy−Ay)+ Cx(Ay− By) |/2  

=|1(4-4)+1(4-1)+-3(1-4)|/2=10/5= 5 sq. units.

1) m - 38 = -44 * m = --6 o m = 6 m = 82 O m = --82​
galina1969 [7]

m-38=-44

    +38     +38       add 38 on both sides, solve for -44 + 38 which is -6.

__________

m = -6, is your final answer.

hope this helps :)

F(x)=x^2-x-1 What is the average rate of change of f over the interval -1<=x<=1
nalin [4]
In calculus, we use derivatives to find the instantaneous rate of change at any point on a graph. To find the average rate of change, we just find the slope of the secant line that intercepts two points on the graph.

We find slope with the following equation:

m =  \frac{y_1 - y_2}{x_1-x_2}

In this case, we are looking for the slope from x = -1 to x = 1. We have both x values, so next we need the y values.

F(-1) = (-1)^2 - (-1) - 1 = 1

F(1) = (1)^2 - (1) - 1 = -1

Now plug in the x and y values to find the slope:

\frac{1-(-1)}{-1-1} =-1

The answer is -1.

Erin writes the set of ordered pairs below. The set represents a function.
tino4ka555 [31]
Point A shows that she is incorrect.
With functions, you can perform the "straight line test through each point. If the line goes through both points, you know it's not a function.
If we plotted point A, it'd fail the straight line test because the given point (-6, 7) already has -6 as an x value.
Hope this helps!
