PLEASE HELP ME PLEASE

y = -2x + 10

Step-by-step explanation:

y = mx + b is slope-intercept form where 'm' is the slope and 'b' is the y-intercept

use the point (2, 6), where 2 is the x-value and 6 is the y-value, and slope of -2 to find the y-intercept:

6 = (2)(-2) + b

6 = -4 + b

b = 10

y = -2x + 10

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
