Answer: Choice A</h3>
The -3 out front of that function means |-3| = 3 is the amplitude, which is the largest of the four functions.
In general, the sine function is
y = A*sin(B(x-C)) + D
where |A| is the amplitude. In the first answer choice, A = -3 so |A| = |-3| = 3.
Cosine has the same format since cosine is just a phase shift of sine.
Answer:
false
Step-by-step explanation:
it fails the vertical line test, (x cannot be equal to 2 or more y values or its not a function)
Answer:
41
Step-by-step explanation:
The entire angle is 90 degrees. So, you make the two equations add up to 90
6x+5+8x+1=90
combine like terms
14x+6=90
subtract 6 from 90
14x=84
divide by 14
x=5
then, plug 5 into angle DBC equation
6(5)+5
=41
Answer:
(a) 16 ft/s
(b) 1.5 s
Step-by-step explanation:
(a) Put 1 where t is in the expression and do the arithmetic:
-32×1 +48 = 16 . . . . feet per second
__
(b) Use the hint and solve for t:
-32t +48 = 0
t -1.5 = 0 . . . . . divide by 32
t = 1.5 . . . . . . . . add 1.5
The ball reaches its maximum height after 1.5 seconds.
N= 12 or - 12 I’m not sure I did it in my head
