Remember that percent just means "out of 100", so 116% is 116 out of 100:

To simplify, you just divide each number by numbers that go into each:

So, 116% in simplified fraction form is 29/25.
45/15= 3
So 1 minute=3 cents
75*3=225=2.25 converted
75 minutes=$2.25
Answer:
cot . (x- π/2)= - tanx
Step-by-step explanation:
cot . (x- π/2)= - tanx
cot .x - cot π/2= - tanx
cot π/2= 1/tanπ/2
But tan π/2= ∞
cot π/2 = 1/∞= 0
cotx - 0= - tanx
cot x = - tanx
cosx/sinx= - sinx/cosx Putting values of cot and tan
cosx/ sinx ( sinx/cos x) = -sinx/cos x (sinx/cos x )
Multiplying both sides with sinx/cos x
1= - sin²x/cos²x
cos²x= - sin²x as cosx = -sinx
Answer:
y-intercept = (0,0)
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
Step-by-step explanation:
here
f(x)=2x^2-1
Now
f(4y)=2*4y^2-1
