What is the area of the figure below?

Troyanec [42]

Answer:

The area of the figure is 7.5 m².

Step-by-step explanation:

Given the lengths of diagonals

2.5 m

The area of the given figure can be computed by multiply the lengths of the diagonals and then divide by 2.

Area = (2.5 × 6 ) ÷ 2

= 15 ÷ 2

= 7.5 m²

Therefore, the area of the figure is 7.5 m².

Help Pre-Calc

Anna11 [10]

Answer:

Average rate of change = 2

Step-by-step explanation:

We need to find the average rate of change of f(x) over the interval [-4,-1], so first we need to find the end points at x=-4 and x=-1.

From graph we see that y=-3 when x=-4, So the point is (-4,-3)

From graph we see that y=3 when x=-1, So the point is (-1,3)

Now we can plug these points into average rate of change formula:

$Average\ rate=\frac{f\left(b\right)-f\left(a\right)}{b-a}$

where (a,f(a)) and (b,f(b)) are the given points.

$Average\ rate=\frac{-3-3}{-4-\left(-1\right)}$

$Average\ rate=\frac{-3-3}{-4+1}$

$Average\ rate=\frac{-6}{-3}$

$Average\ rate=2$

Hence final answer is 2.
