Answer:
60° =
radians
Step-by-step explanation:
To convert from degrees to radians
radian measure = degree measure × 
Thus 60° in radian measure
= 60 ×
( divide ( cancel) 60 and 180 by 60 )
= 
Answer:
<u>Given equations</u>: y = 3x² + x - 6; y = x - 4
So, Plug the value of value of y in other equation
- 3x² + x - 6 = x - 4
- 3x² + x - x - 6 + 4 = 0
- 3x² - 2 = 0
- 3x² = 2
- x² = 2/3
- x = √2/3
Answer:
There are 11 four person passengar cars
Step-by-step explanation:
let's call the number of four person cars A , & the number of six person cars B
there are 3 less 6 person cars than 4 people cars which can be written as:
A - 3 = B
there are also 92 total people that can go on max on the whole ride which can be written as:
4A + 6B = 92
Now we need to subsitute in our first equation into the second, so:
4A + 6(A-3) = 92
then distrbute the 6:
4A + 6A - 18 = 92
bring like terms to the same side & consolidate:
4A + 6A = 92 + 18
10A = 110
divide the right by # of A to get a single term :
A = 110/10
A= 11
Plug in F(x) to the equation answer and see if it is true or false by plugging it in
