What is the perimeter of this figure

100mm

Step-by-step explanation:

Perimeter is the size of the outer part of the figure. And in this figure, we have a triangle and a semicircle joined together.

Formulae for finding the perimeter of a circle is 2πr, and since it's a semicircle, we divide the answer by 2. Where π is 3.14

2(3.14)(16)/2

50.24

Adding the other parts

50.24+40

90.24

Rounding up to the nearest hundred, we have the number between 0 and 100. 90 is closer to 100 than 0.

Hence, the answer is 100

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

is this part of a question or something
