Answer:
cos(x)=0.6
Step-by-step explanation:
cos(x) represents the horizontal distance of the unit vector
sin(x) represents the vertical distance of the unit vector (0.8)
tan(x) represents the distance on the tangent line from the point to the x-axis
cot(x) represents the distance on the tangent line from the point to the y=axis
Answer:
C = 20
Step-by-step explanation:
The sum of the angles of a triangle is 180
73+87+c =180
Combine like terms
160 +c = 180
subtract 160 from each side
160+c-160 = 180-160
C = 20

Answer:
Step-by-step explanation:
Known facts
- Marisol burned 670 calories
- Ling burned x fewer calories than Marisol
Setting up the equation
# of calories that Ling burned = Marisol's calorie - x = 670 -x
Hope that helps!
Answer:
Step-by-step explanation:
You can tell by looking at the form of each equation.
y = tx
This is a straight line that passes through the origin, so it symmetric with respect to the origin.
y = x²+1
This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.
y = x²+x = (x+½)² - ¼
This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.
Can't tell what "y = (1 + x2)3" means. Which terms are exponents?
