Answer:
Step-by-step explanation:
Correct option is
D
[1,(1+π)
2
]
f(x)=(1+sec
−1
(x))(1+cos
−1
(x))
Here the limiting component is cos
−1
(x), since the domain of cos
−1
(x) is [−1,1].
Therefore,
f(1)=(1+0)(1+0)
=1
f(−1)=(1+π)(1+π)
=(1+π)
2
Hence range of f(x)=[1,(1+π)
2
]
The answer to A is yes because of a 3-4-5 triangle. The answer to B is no
Answer:
B
Step-by-step explanation:
First, subtract 3 by the numbers
-8 > 4x > 4
Remember to flip the inequality signs
Second, divide all the numbers by 4
-2 < x < 1
Flip the inequality signs again
-2 > x > 1
I am not very experienced with these problems so I might be wrong.
The answer should be X= 3.60m
Answer:
y = -6x — 13
Step-by-step explanation:
use y = mx + b equation and plug in what you know.
5 = -6(-3) + b —> solve for b
b = -13 —> plug in what you know into y=mx+b
ANSWER: y = -6x — 13
