In physics class, Carrie learns that a force, F, is equal to the mass of an object, m, times its acceleration, a. She writes the equation F=ma.Using this formula, what is the acceleration of an object with F=7.92 newtons and m=3.6 kilograms? Express your answer to the nearest tenth.Note: The unit for Force (the Newton) is measured in .

The slope-intercept form of a linear equation is y = mx + b, where x and y are coordinates of an ordered pair, m is the slope of the line, and b is where the line crosses the y-axis.

m = yx + b

m =

m = – b

m = y –

Which are equivalent equations? Select two correct answers.

s =

s = LAr

r =

r = LAs

Solve for w.5w + 9z = 2z + 3w

w = z

w = –2z

w = –7z

The slope, m, of a linear equation can be found using the formula m = , where the x- and y-values come from two ordered pairs, and (x1, y1) and (x2, y2).

y2 = mx2 – x1 + y1

y2 = mx2 – x1 – y1

y2 = m(x2 – x1) + y1

y2 = m(x2 – x1) – y1

The circumference of a circle can be found using the formula C = 2r.

r = C

r = C(2)

r =

The equation d = can be used to calculate the density, d, of an object with mass, m, and volume, V. Which is an equivalent equation solved for V?

dm = V

= V

m – d = V

The goals against average (A) for a professional hockey goalie is determined using the formula A = 60 . In the formula, g represents the number of goals scored against the goalie and t represents the time played, in minutes.
