Cos x + 2sec x = -3
cos x + 2/cos x = -3
cos^2 x + 2 = -3cos x
cos^2 x + 3cos x + 2 = 0
(cos x + 1)(cos x + 2) = 0
cos x + 1 = 0 or cos x + 2 = 0
cos x = -1 or cos x = -2 [but cos x cannot be -2, so we discard it]
x = arccos(-1)
x = (2n + 1)π
Answer:
many solutions
Step-by-step explanation:
You have to attribute values to x, and then you find the y value.
The x value you attributed and the y value you got as a result will be an ordered pair of the linear equation
For example:
x = 4
y = 3*4-7
y = 5
(4 | 5) is an ordered pair.
x = 3
y = 3*5-7
y = 8
(3 | 8) is another one.
Link the 2 points and you will find a line
First, find the area of the plot:
25*10=250
1000/250 is 4
the population density is 4 squirrels per square foot.
