The perimeter of the square to the right is 40cm what is the length of the diagonal

the question does not present the picture, but this does not interfere with the resolution

we know that

perimeter square=4*b

where

b is the length side of the square

perimeter=40 cm

so

4*b=40

b=40/4

b=10 cm

Find the diagonal applying the Pythagoras Theorem

D²=b²+b²> D²=10²+10²> D²=200> D=√200

D=10√2 cm

the answer is

use formula for the circle a=3.14

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
