Answer:0.4813042802
Step-by-step explanation:
We have to prove that the tangent is an odd function.
If the tangent is an odd function, the following condition should be satisfied:
From the figure we can see that the tangent can be expressed as:
We can start then from tan(t) and will try to arrive to -tan(-t):
We have arrived to the condition for odd functions, so we have just proved that the tangent function is an odd function.
Answer:
Each person paid $24.
Step-by-step explanation:
1. Find 20% of 40. Since 20% is equal to 1/5, we can divide 40 by 5 to get 8. Together they tipped $8.
2. We know that the total amount they paid was $48, so we divide that in half to get the answer. 48 divided by 2 is 24.
Answer:
When we have a discount of X% of the original price, the new price is calculated as:
New price = (original price) - (original price)*(X%/100%)
In our case, let's define:
P = original price of the fishing pole
f = price of the fishing pole after the discount
X% = 20%
Then the equation for the price of the fishing pole is:
f = P - P*(20%/100%) = P - P*0.2 = P*(1 - 0.2) = P*0.8
f = 0.8*P
This means that the price after the discount is 0.8 times the original price.
