Answer:

x = 7

Step-by-step explanation:

I think there may be other ways to do this ... but this is one I guess....

one angle= 90 ( given)

the other = 45 (given)

the third = 90 + 45 + a = 180

(all angles of triangles is 180 [angle sum property])

a = 180 - 135

= 45

The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal , so

if one side is 7

the x is 7 too

(as it cant be the hypothenus)

I think this is right

Given that the average rate of change for y = f(x) over the interval [0,3] is −1, the average rate of change over the interval [

Svet_ta [14]

Answer:

Answer is 2

Step-by-step explanation:

We know that average rate of change of a function f(x) in the interval (a,b) is

$\frac{1}{b-a} \int\limits^a_b {f(x)} \, dx$

Using this we can say that

$\int\limits^0_3 {f(x)} \, dx =-1(3)=-3\\\int\limits^2_3 {f(x)} \, dx =5(1)=5\\\\\int\limits^2_6 {f(x)} \, dx =4(5)=20\\$

Using properties of integration we have

3 to 6 integral = 20-5 =15

0 to2 integral = -3=5 =-8

Thus integral form 0 to 6 would be = -8+15+5 = 12

Average rate of change form 0 to 6 = $\frac{12}{6} =2$

To find the area of a triangle, multiply the height (6) by the base (4) and divide by 2.
- 6 • 4 = 24, 24 / 2 = 12.
The area of this triangle is 12.
