X + 2 1/2 - 3/4 = 5 1/4   To find x, go backwards in the equation.
5 1/4 + 3/4 = 6 cups
6 - 2 1/2 = 3 1/2 cups
x = 3 1/2 cups

Use trigonometric identities to solve the trigonometric equation sin(2∅)-cos(∅)=0 for 0≤∅≤2π. You must show all of your work ana
SOVA2 [1]

Step-by-step explanation:

sin(2x) = 2sin(x)cos(x)

2sin(x)cos(x) - cos(x) = 0

so one solution is cos(x) = 0.

=> x = pi/2 and 3pi/2 (90° and 270°)

for cos(x) <> 0 we have then

2sin(x) - 1 = 0

2sin(x) = 1

sin(x) = 1/2

=> x = pi/6 and 5pi/6 (30° and 150°)

X. Y
Dovator [93]

Answer:

Slope:  5

Y-intercept:  0

Equation:  y=5x

Step-by-step explanation:

Lets look for an equation of the format y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).

Slope is defined as the "Rise/Run" of the line.  The change in y(the rise) for a change in x(the run).  This can be calculated by taking any two of the given data points.  I'll pick (1,5) and (5,25):

Rise = (25 - 5) = 20

Run = (5 - 1) = 4

The Rise/Run, or slope, m, is (20/4) or 5.

<u>The equation becomes y = 5x + b.</u>

To find b, the y-intercept, enter <u>any</u> of the points into the equation and solve for b:

y = 5x + b

y = 5x + b   for (4,20)

20 = 5*(4) + b

b = 0

The line goes through the origin at x = 0 (0,0).

The equation is y = 5x + 0 or just y = 5x.

Slope:  5

Y-intercept:  0

Equation:  y=5x

Another friend, with a mass of 75 kg, wants a push on the swing. How much force will
NeX [460]

Answer:

735N

Step-by-step explanation:

According to Newton's second law;

Force = mass * acceleration due to gravity

'

Given

Mass = 75kg

Acceleration = 9.8m/s^2

Substitute into the formula;

F = 75 * 9.8

F = 735N

Hence the force required is 735N
