4.If a circle has a circumference of about 12.56 cm, what would we do to determine the radius? Use 3.14 as “pi”. 5.A circle has a diameter of 10 inches. Explain how to find the area of that circle. Use 3.14 as “pi”.
6.Explain a cross section that would be created if you were to cut a square pyramid horizontally.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

m=-16
