Answer:
38°
Step-by-step explanation:
a²=b²+c²-2bc cos A
5²=3²+7²-2(3)(7) cos A
-33 = -42 cos A
A = 
(-33/-42)
A = 38°
Answer:
10
Step-by-step explanation:
Domain is all real numbers
range
hmm
we know that x^2=a positive number
then multiply it by that negative -3
therefor the range is going to be mostly negative
if we make the x-5 equal to zero, then there is no negative, so
wher x=5, then f(5)=0+4=4
the highest positive number you can get is f(5)=4
so therfor
domain=all real number
range is x≤4
Answer
No missing money
Step-by-step explanation:
Original money given to the waiter = $30
Each person paid $10
The waitress comes back with the waitress comes back and said the bill is $25
They gave her $2 for the tip
if each got $1.00 back
Balance = $1.00 × 3
= $3.00
That means each paid $9×3 = $27 including $2 .00 tip(recall that cost of the meal is now $25 plus $2 tip)
Each of them got $1.00 back
Total money spent = (cost of meal + tip) + balance of $3.00 given to them
= $27 + $3
= $30
Therefore, there is no missing $1.00
