right triangle

Step-by-step explanation:

We can use the Pythagorean theorem to determine if this is a right triangle

a^2 + b^2 = c^2

13^2 + ( 8 sqrt(13)) ^2 = (sqrt(1001))^2

169 + 8^2 * 13 = 1001

169+64*13 = 1001

169+832=1001

1001 = 1001

Since this is true, this is a right triangle

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
