yea

okay thanks so much

what is your question?

hang on

The image below is a triangle drawn inside a circle with center O:Which of the following expressions shows the area, in square inches, of the circle?
(π = 3.14)
3.14 · 42
3.14 · 52
3.14 · 5
3.14 · 22

the diameter of the circle is 8" so the radius is 8/2

area of circle is 4^2π

16 times pi

now lets find the area of the triangle

i think we only need to find the circle/

yea

so a?

In triangle XYZ, z2 = x2 + y2.
Which equation is true about the measure of the angles of the triangle?
The measure of angle XZY is equal to 90 degrees
The measure of angle XYZ is equal to 100 degrees
The measure of angle XYZ plus the measure of angle YXZ is equal to 80 degrees
The measure of angle XYZ plus the measure of angle YXZ is equal to 70 degrees

its not in the option

first one is true

so a?

this stuff is a right angle triangle thats why it runs with pythagoras theorem

yea

A wooden block in the shape of a rectangular pyramid is shown below:
If a cross section of the block is cut perpendicular to the base but does not pass through the top vertex, which of the following shapes describes the cross section?
Triangle
Rectangle
Trapezoid
Hexagon

trapezoid

|dw:1438954292309:dw|

imagine it being cut like that

dilation means scaled down so this thing reduced by half in size

congruent means they are equal length in all sides

you should know the answers by now

i know that i just dont know how to do it:(

|dw:1438954561117:dw|

it is going to be similar bc we r cutting the size down to half

yes similar but not congruent

what would be the coordinates?

since this is a multiple choice question you can test it out

divide the coordinates of the original triangle by 2

A(4, −6), B(2, −8), and C(−10, 4)
New triangle: A (4/2, -6/2) B (2/2, -8/2) C (-10/2,4/2)

2,-3

is it a ?

yep

yea c

Which sequence of transformations will change figure PQRS to figure P′Q′R′S′?
Counterclockwise rotation about the origin by 90 degrees followed by reflection over the x-axis
Counterclockwise rotation about the origin by 90 degrees followed by reflection over the y-axis
Counterclockwise rotation about the origin by 180 degrees followed by reflection over the x-axis
Counterclockwise rotation about the origin by 180 degrees followed by reflection over the y-axis

is it a?

definitely the last 2 options

c?

lemme check, i dont remember a thing about those already

yea its A

rotate to 4th quadrant then reflection to 1st quadrant from x-axis

really? i usually never get these right

|dw:1438955704612:dw|

thank u so much i got a 93 :)

a is the only option that fits in

lol yw

will u be available later?

maybe

sometimes i fall asleep with my pc on

if i dont reply within 20mins, im prolly sleeping or playing dota2
