y=mx+b

b= y intercept

m=slope or it can also be written as \(\frac{\Delta y}{\Delta x}\)

x= is the x intercept

yes but it would simplify to a whole number

example \(3\sqrt{2}^2=6\)

p=3/10

4/2=2 add 2 zero's

so 400

10/2=5 add 2 zero's

so 500

then add them together 500+400=900

121 It's a very special number

So the mirror is 60ft from the base of his school clock tower b

He walks backwards an x amount of times until he can see the top of the clock tower in the mirror,

At this point, his eyes are 6 ft above ground, and he's 7.5 ft away from the mirror, .

Let the top of the tower be T and let M be mirror

So we know the tower is \(T\geq 6\)  

He walked 7.5ft away from the mirror so let x=7.5ft

So we now have the base lenght and height I.e 2 sides

so we know that the max height of the Tower cannot excead 60ft since he would be going past his mirror.

So \(T\leq 60 \)  so now we have this inequality

\(6\leq T\leq 60\)

This is actually a Pythagores question since we know the max heght can't excead 60 and can't go below 6

so it's 60^2-7.5^2=c^2

So the height is 59.6 to 1 decimal place! *Made a mistake instead of 6 we are subtracting 7.5 ft so

its 60^2-7.5^2=3543 and the sqrt of that is 59.5 to 1 decimal place! sorry for the mistake

The points will be

(-2,0.64) for when x=-2

(-1, 0.8) for when x= -1

(0,1) for when x=0

(1,1.25) for when x=1.25

(2, 1.5625) for when x=2 (1.5625 can be written as (25/16)

Which kind of Kinectic energy?

7 gallons = 4 classrooms

14 gallons= 8 classrooms

so 14*2=28 gallons

hence 28 gallons = 16 classrooms

we must first figure out the force of the bullet with

F=ma so 10g*500  =5000N

So the bullet will produce a horizontal force of 5000N

so 5000N at the speed of 500/ms

the final speed is 5000/500=10/ms(^-2) in horizontal force

Sorry if i made some mistakes, i'm not amazing at physics
