Hello,
cos 160°=-q
cos 20°=-cos 160°=q
sin 20°=√(1-q²)=sin 160°
tan -20°=tan 160=√(1-q²)/-q
cos 70°=sin 20°=√(1-q²)
To solve for x, add 3 to both sides, multiply both sides by -1, then take the square both sides.
The quadrant would be the first one, because once reflected over the y-axis, it would become (2,-8), and once reflected over the x-axis, it would become (2,8)
The probability notation for choosing a red disk is P(red disk)
<h3>How to determine the notation?</h3>
From the question, we have the following highlights:
- The scenario represents probability
- The event is choosing a red flask
Probability notations are represented as:
P(Event)
Since the event is choosing a red flask, the probability would be
P(red disk)
Hence, the probability notation for choosing a red disk is P(red disk)

Answer:
40% number of calories have increased
Step-by-step explanation:
Old Value ( Calories consume before) = 2000
New Value (increase in Calories consumed) = 2800
We need to find by what percent did the number of calories increase
To find percent increase, the formula used is:
Putting values in formula and finding percent increase
So, 40% number of calories have increased
