The question is find the equation, in the function and standard notations, that represent the amount spent in the range of 0 to 5 rides.
Constant cost: $30
Independent variable, number of rides: r
Variable cost: $2r
Total spend, s(r): 30 + 2r
Function: s(r) = 30 + 2r, for 0 ≤r ≤ 5 ----- this is the function notation
Standard form: s(r) is the dependent variable = s
s = 30 + 2r => s - 2r = 30 =>
s + (-2)r = 30, for 0 ≤ r ≤ 5 ------ this is the standard form
Answer:
The answer to your question is 
Step-by-step explanation:
Data
cos Ф = 3/5
tan2Ф = ?
Quadrant IV
Process
1.- Remember that tanФ = 
and cos Ф = 
then, adjacent side = 3 and hypotenuse = 5
2.- Calculate opposite side
O² = h² - a²
O² = 5² - 3²
O² = 25 - 9
O² = 16
O = 4
3.- Calculate the tan 2Ф
tan 2Ф = 2(
) The opposite side is negative in the fourth
quadrangle
tan 2Ф =
the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.
x+(2x+15)+the measure of angle Q should equal 180.
Since everything is addition, the parenthesis can be removed.
x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.
Unfortunately I don't really know what to do from here, but I hope it helped at least a little.
0.05,reverse. if you have 0.05 and times it by 100 you get 5% and I divided 5% by 100 to get the answer, hope this helps! :)
Answer:
7000
