Answer:
b) 5π/4
c) 7π/4
e) 13π/4
Step-by-step explanation:
sin θ = -½√2
There's really no algebra to be done here. There are two ways you can solve. One, you can use a calculator. Two, you can memorize your unit circle.
Either way, it helps to draw the unit circle. sin θ is the y coordinate, so you're looking for points on the circle where y = -½√2. This happens at two places: θ = 5π/4 and 7π/4.
Next, we need to check the options that are greater than 2π.
9π/4 is the same as π/4.
13π/4 is the same as 5π/4.
So the three correct answers are 5π/4, 7π/4, and 13π/4.
Answer:
Step-by-step explanation:
To simplify the square roots, break the number under the square root into factors. Any factors which are perfect squares may be simplified to outside the square root.

The probability of making money on the first day and losing money on the second day and making money on the third will be 14.4%.
<h3>What is probability?</h3>
The probability of an event occurring is defined by probability.
Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
There are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.
Given that,
Probability of making money = 0.60
Probability of not making money = 0.40
So,
Probability of making money on the first day and losing money on the second day and making money on the third = 0.60 × 0.40 × 0.60
⇒ 0.144 = 14.44%
Hence "The probability of making money on the first day and losing money on the second day and making money on the third will be 14.4%".

Answer:
a. 1/3
Step-by-step explanation:
y=x/3-5 (rewrite x - term)
y = (1/3) x + 5
recall that in the slope-intercept form of a linear equation y = mx + b
m is the slope.
In our case, we can clearly see that slope m = (1/3)
