Explanation:
Factorizing your equation we get
cot
(
x
)
=
0
so
cos
(
x
)
=
0
we get the following Solutions in the given interval
x
=
π
72
or
x
=
3
π
2
for the second case we get
cot
(
x
)
=
−
1
so
cos
(
x
)
=
−
sin
(
x
)
and we get
x
=
3
π
4
or
x
=
7
π
4
Hint:
To get the Solutions of the last equation you can use
√
sin
(
x
+
π
4
)
=
0

Answer:
False
Step-by-step explanation:
The same function input (the first number in the pair) cannot have two different outputs (the second number in the pair).
(6, 4) 4 is one output.
(6, -4) -4 is another output.
Answer:
The decimal number is 0.964
Step-by-step explanation:
we have
![9(\frac{1}{10})+ 6(\frac{1}{100})+4(\frac{1}{1,000})](https://tex.z-dn.net/?f=9%28%5Cfrac%7B1%7D%7B10%7D%29%2B%206%28%5Cfrac%7B1%7D%7B100%7D%29%2B4%28%5Cfrac%7B1%7D%7B1%2C000%7D%29)
step 1
Multiply each fraction by the whole number
![(\frac{9}{10})+ (\frac{6}{100})+(\frac{4}{1,000})](https://tex.z-dn.net/?f=%28%5Cfrac%7B9%7D%7B10%7D%29%2B%20%28%5Cfrac%7B6%7D%7B100%7D%29%2B%28%5Cfrac%7B4%7D%7B1%2C000%7D%29)
step 2
Convert each fraction in a decimal number
Remember
Move the decimal point to the left as many places as there are zeros in the factor.
Move the decimal point one step to the left (10 has one zero).
Move the decimal point two steps to the left (100 has two zeros)
Move the decimal point three steps to the left (1000 has three zeros)
![0.9+0.06+0.004](https://tex.z-dn.net/?f=0.9%2B0.06%2B0.004)
step 3
Adds the number
![0.964](https://tex.z-dn.net/?f=0.964)

Answer:
Q' (-2, 2)
P' (-2, 7)
R' (6, 2)
Step-by-step explanation:
When reflecting over a diagnal line such as y = x or y = -x, a trick is to count the boxes at an angle to see how many spaces it is away from the line. Be sure to recipicate what you counted the first time, and when reflecting over y = -x, flip the x and y coordinates and if needed, change the signs.
Hope this helps!
