Use the function rule, y = 2x + 5, to find the values of y when x = 1, 2, 3, and 4. Write the answers as ordered pairs that would be used to graph the function. can someone help me i'm stuck on this question

The first thing you want to do is get rid of x in the denominator, because that simplifies things quite a bit. Think of the easiest common denominator between 9/x and 9/(x-2), which would be x(x-2). You know that x-2/x-2 = 1, regardless of the value of x; the same with x/x, so...

10^5.4 = 251188.6432 = 2.5 X 10^5 You can just plug this in the calculator. I think it's two significant figures

t(Earth) = t(satellite) / (square root) 1 - (v/c)^2 = t(satellite) / (square root) 1 - [ (3.9 x 10^3) / (3x 10^8)^2 ] = (1 - 1.7 x 10^-10)^ - 1/2 [ t(satellite) ] t(Earth) = (1 + 8.5 x 10^-11) [ t(satellite) ] GMEarth = (6.67 x 10^-11 N x m^2/kg^2) (5.98 x 10^24 kg) = 4.0 x 10...

A GPS satellite orbits at an altitude of 2.0 x 10^7 m and a speed of 3.9 x 10^3 m/s, Earth’s radius is 6.4 x 10^6 m, and a point at its equator has tangential speed of 460 m/s, By approximately what fraction must the time be adjusted to account for both regular/speed-depe...

The kinetic energy of a proton is half its internal energy. What is the proton's speed? Kinetic energy is (Yu - 1) (mp) (c)^2 = 1/2 (mp) (c)^2 Yu = 1.5 Yu = 1/(square root) 1 - (u/c)^2 1/(square root) 1 - (u/c)^2 = 1.5 u= 0.745c How do I solve for u? I'm extremely conf...
