For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2.

PLEASE HELP

Answer:

y = -x +3

m = -1

b = 3

Step-by-step explanation:

To solve the given equation for y, divide by the coefficient of y.

(-3y)/(-3) = (3x -9)/(-3)

y = -x +3

The slope is the x-coefficient, M = -1.

The y-intercept is the added constant, B = 3.

Both equations are graphed in the attachment. Texture has been added to the original so you can see the graphs are the same line.

A triangle has a base that is 3 times the height. The area of the triangle is 63 cm^2. Find the height of the triangle. Round yo

Anni [7]

Answer:

Step-by-step explanation:

Let height = x cm

Base = 3x cm

Area of triangle = 63 cm^2

$\frac{1}{2}*3x*x=63\\\\\frac{1}{2}*3*x^{2}=63\\\\x^{2}=63*\frac{2}{3}\\\\x^{2}=21*2\\x^{2}= 42\\\\$

x = 6.48

Height = 6.5 cm
