Cos t (sec t - cos t)
= cos t (1 / cos t - cos t)
= 1 - cos^2 t
= sin^2 t (using the identity sin^2 t + cos^2 t = 1 )
Answer:
The range of a relation is the output (y) values of the relation. The range represents the set of the y-coordinates from the ordered pairs.
Step-by-step explanation:
Answer:
1350
Step-by-step explanation:
multiply 40% and 2250
equals 900
subtract 900 from 2250
Answer:
The y intercept is 0
The x intercept is -1
Step-by-step explanation:
To find the y intercept set x = 0 and solve for y
y =x^3 +1
y = 0+1
y =1
The y intercept is 0
To find the x intercept set y = 0 and solve for x
0 = x^3 +1
Subtract 1 from each side
-1 = x^3
Take the cube root of each side
(-1) ^ 1/3 = x^3^1/3
-1 =x
The x intercept is -1
