Answer:
B. tan (-180°) = 0
Step-by-step explanation:
Tangent is the ratio of opposite to adjacent to an angle
From the unit circle; the opposite to our angle -180° is 0
The adjacent along the x-axis is 1
Therefore;
Tan (-180°) = 0/1
= 0
Therefore; Tan (-180°) is 0

Step-by-step explanation:
but i don't see any table
9.8(k+9)−5.7
Distribute:
=(9.8)(k)+(9.8)(9)+−5.7
=9.8k+88.2+−5.7
Combine Like Terms:
=9.8k+88.2+−5.7
=(9.8k)+(88.2+−5.7)
=9.8k+82.5
Answer:
=9.8k+82.5
Answer:
C 7ft/yr
Step-by-step explanation:
The given points are not all on the same line, so the average will vary depending on the interval of interest.
Over the interval [1, 11] years, the average rate of change of height is ...
change in height / change in years = (80 -10)/(11 -1) = 70/10 = 7 . . . ft/yr
__
On the interval [11, 15] years, the average rate of change is ...
(105 -80)/(15 -11) = 25/4 = 6.25 . . . ft/yr
Even on this interval, the closest answer choice is C.
Answer:
hello :
f(x) = -x+0.25
g(x) = x²+3x+2
ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ
f(-3.5) = 3.75
g(-3.5) = 3.75
ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ
f(-0.5) =0.75
g(-0.5) = 0.75
ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ
conclusion : answer : A) x = −3.5 and x = −0.5
Step-by-step explanation:
Hope this helps:)
