Answer:
x = 55.94 degrees
Step-by-step explanation:
(to find x, use cosine) (cos = )
<em>First step: write out the equation</em>
⇒ cos x =
<em>Second step: find out what </em><em> is </em>
⇒ = 0.56
<em>Third step: find out what the cos-1 of 0.56 is</em>
⇒ cos-1 of 0.56 = 55.94
Fourth step: you got your answer
⇒ x = 55.94
The request is to find the intersection of the two sets. By definition, the intersection of two sets is another set, composed by all the elements appearing in both sets.
In other words, is the set of all elements that P and Q have in common.
P contains all the numbers from 0 to 9, V contains all the odd numbers between 1 and 19. So, their intersection will be the odd numbers between 0 and 9, i.e.
The question is incomplete. Here is the complete question:
Val rented a bicycle while she was on vacation. She paid a flat rental fee of f dollars, plus $8.50 each day. The total cost at the end of her vacation was t dollars. Let d represent the number of days Val rented the bicycle. Write an equation representing the total cost at the end of her vacation.
Answer:
Step-by-step explanation:
Given:
Flat rental fee =
Variable fee per day = $8.50
Total cost at the end vacation =
Number of days of her vacation =
Using unitary method, we can find the variable fee for 'd' days.
1 day variable fee = $8.50
Therefore, 'd' days variable fee =
Total cost at the end of her vacation can be obtained by adding the fixed rental fee and the variable fee obtained for the given number of days.
Now, total cost is given as:
Total cost = Flat rental fee + Variable fee
Substituting all the variables and framing above in the form of an equation, we get:
Therefore, the equation representing the total cost at the end of her vacation is
