PEMDAS! do the things in the ( ) first. that'd be b-4 which is probably base minus four then multiply by six.

If by MB you mean Megabyte (not Megabit) then: 18 MB = 18*8 = 144 Megabits 144/4 = 36 seconds

when u have an even power, the value of y will always be positive, when u have an odd power, the value of y will be negative for x < 0 The higher the power the steeper the slope will be the graphs of x^n for even and odd n's are the same except that they are inverted ar...

work = forcs*distance = 70*1.1 = 77 N.m

**physics**

Current velocity = (time)*(acceleration) + initial velocity 12 = (0.96)*acceleration + 0 acceleration = 12.5 m/s2

**physics**

Current velocity = (time)*(acceleration) + initial velocity 22.5 = time*4 + 0 time = 22.5/4 = 5.625 seconds

**algebra 2**

unless there is a special definition of "average rate of change" that im not aware of, ur answer is (f(19) - f(6))/(19-6)

**PHY**

More electrons than protons means the object has a negative charge Since a CL^-1 ion is negative, the two will repel each other

y=2x-2 y+2=2x (y+2)/2 = x y/2 +1 = x Answer: x=y/2+1

1st you find the vertical component of its speed which = (120)sin(60)=103.92 m/s Gravity's pull will decrease its vertical speed by G (=9.8 m/s^2) Therefore the vertical velocity of the projectile = 103.92 - (9.8)*t (whee t is time in seconds) It will reach maximum height ...

useing these numbers: 25 - 7 - 8 - 5 - 4 - 3 make an equation so that the answer equals 828,but you can ONLY use those numbers. you cant add any more numbers and you cant repeat any of the numbers. you DONT have to use all the numbers though
