at an amusement park a person spends $30 on admission and food and then goes on r number of rides that cost $2 each
stepladder [879]
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

Find tan2θ if θ terminates in Quadrant IV and cosθ =3/5 .
Liula [17]

Answer:

The answer to your question is  \frac{-8}{3}

Step-by-step explanation:

Data

cos Ф = 3/5

tan2Ф = ?

Quadrant IV

Process

1.- Remember that tanФ = \frac{Opposite side}{Adjacent side}  and cos Ф = \frac{adjacent side}{hypotenuse}

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(\frac{-4}{3})       The opposite side is negative in the fourth

                                           quadrangle

            tan 2Ф = \frac{-8}{3}

Help!!! Will give brainliest!!
Serhud [2]

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.
