You keep adding 2 and 1/3 to get your answer
Answer:
We have sin² x + cos² x =1 for all real x.
Therefore, sin² x = 1 – cos² x = 1 – (8/17)² = 1 – 64/289 = 225/289 = (15/17)².
However, remember that if x² = a², then x can be +a or –a.
Therefore, sin x can be either –15/17 or +15/17.
Everyone but Anirban so far has forgotten the negative solution.
Step-by-step explanation:
Given that sinθ=817 and cosθ<0 , we have: cosθ=−√1−sin2θ. cosθ=−√1−(817)2. cosθ=−√1−64289.

Answer:
Domain : (-∞,∞) Range : (-∞,∞)
Step-by-step explanation:
Given:
f(x) = 3x+5
To find: Domain and Range of f(x)
Domain is the set of values that x can take.
Range is the set of values of y corresponding to the values of x in the domain.
Here x can take any value and the domain is the set of real numbers i.e (-∞,∞).
f(x) = 3x + 5
The graph of f(x) is a straight line that extends from -∞ to +∞ and hence the range is (-∞,∞).
Answer:
Bob will spend on ice cream for the team $20.25
Step-by-step explanation:
Hello!!!
In this problem we are expected to solve for the total amount that Bob will spend to buy
8 players ice cream cookies and
5 players ice cream cones
let us calculate as follows
Cost of ice cream cookies for 8 players = 8*1.75= $14
Cost of ice cone for 5 players = 5*1.25= $6.25
Total cost = $14+ $6.25= $20.25
