Answer:First make sure your calculator is on the right setting which would be a DEG. Then depending on the problem you would press COS, put whats needed inside the parentheses and close it.

Or if a different kind of problem you would press 2nd on the top of the calculator then Cos and continue the same way as the first one.

Can anyone find the x and y intercepts for this equation?

ASHA 777 [7]

1/3x - 1/2y = 1

At the 'x' intercept, y=0 , and the equation is 1/3 x = 1

Multiply each side by 3 : x = 3  <== the x-intercept

At the 'y' intercept, x=0, and the equation is -1/2 y = 1

Multiply each side by 2 : - y = 2

Multiply each side by -1 :  y = -2  <== the y-intercept

Use the formula A = P(1 + r)" to solve.

Llana [10]

Answer:

Rate = 0.45 or 45%.

Step-by-step explanation:

20184 = 9600(1 + r)^2

(1 + r)^2 = 20184/9600 = 2.1025

Taking square roots of both sides:

1 + r = 1.45

r = 1.45 - 1 = 0.45.
