B
Step-by-step explanation:
The result says y=-x+5 which can be rearrange d to x+y=5
Answer: (1, √15) and (1, -√15)
Step-by-step explanation:
A circle centered at the point (a, b) of radius R can be written as:
(x - a)^2 + (y - b)^2 = R^2
In this case we have:
"A circle is centered at the origin (0,0) and has a radius of 4 units"
Then the equation for this circle is:
x^2 + y^2 = 4^2 = 16.
Now, we want to find the points where x = 1, then we can replace that value and solve the equation for y.
1^2 + y^2 = 16
1 + y^2 = 16
y^2 = 16 - 1 = 15
y = +-√15
Then the two points that have the x-coordinate equal to 1 are:
(1, √15) and (1, -√15)
Answer:
A is more than 1 (assuming you meant one) and b is less than 1.

Answer:
Option C.
Step-by-step explanation:
By definition, a function f(x) is even if 
We know by definition that the function sin(x) is odd and the function cos(x) is even.
With this information we can analyze each function and find out which is even.
A. The first function is not even because 5sin(x) is an odd function.
B. The second function is not even because 2tan(x) is not an even function.
C. The third function is even, because -cos(x) and
are even functions.

D. The fourth function is not even because csc(x) is not an even function.
Therefore the correct answer is the option C.
