Answer:
positive
Step-by-step explanation:
Using the acronym ASTC (all students take calculus), this means that if sin and tan are negative, they must be in the fourth quadrant, which means that cos is positive.
ASTC is an acronym to help students remember which of the three basic trigonometric functions are positive in which quadrants.
A: all
S: sin
T: tan
C: cos
It starts from the first quadrant: all the sin, tan, cos are positive in the first quadrant, only sin is positive in the second quadrant, only tan is positive in the third quadrant, only cos is positive in the fourth quadrant.
Answer:
c) 28
explanation :
In this sequence:
a1 = 2
a2 = 4
a3 = 6
a4 = 8
a5 = 10
and so on...
then
the sum from a2 to a5 is:
a2 +a3 + a4 + a5 = 4 + 6 +8 + 10 = 28
Answer:
The most likely reason for the bill being this amount would be the registration fee.
Step-by-step explanation:
The most likely reason for the bill being this amount would be the registration fee.
Let x be the number of months
Let y be the monthly payment
Then according to the given situation we can model a function which is:
y=45x+15
put x = 1 for the first month
y=45(1)+15
y=45+15
y=60
Thus the reason for the bill being this amount would be registration fee....
the graph would steeper, meaning more savings over time
