Check the picture below.
notice, that one go-around is 2π, or namely 4π/2, and if we go 3π/2 more over, we'd end up at at 4π/2 + 3π/2 or 7π/2.
a couple of coterminal angles will be those in blue, one angle in the first go-around, and another one by simply going around one more time by 4π/2 extra, 7π/2 + 4π/2 is just that one there.
Step-by-step explanation:
<u>Step 1: List out all of the formulas for the trigonometric functions
</u>
<em>sin(x) </em>= opposite/hypotenuse
<em>cos(x) </em>= adjacent/hypotenuse
<em>tan(x) </em>= opposite/adjacent
<u>Step 2: Find the following expression that has a value of 2/5
</u>
sin(B) = opposite/hypotenuse = ?/5 is FALSE
cos(B) = adjacent/hypotenuse = 2/5 is TRUE
tan(B) = opposite/adjacent = ?/2 is FALSE
Answer: The correction expression that has a value of 2/5 is option B
Answer:
Step-by-step explanation:
Given:
Vertex of the parabola is, 
Equation of the parabola in vertex form is given as:
Plug in 
. This gives,
Therefore, the equation of the given graph is
.
Answer:
c)
Step-by-step explanation:
16) Cost price = Selling price * 100 / (100- loss%)
= 800 * 100 / 80 = 10*100 = 1000
Loss = Cost Price - Selling price = 1000 -800 = 200
Answer:
Firstly you have to know the x and y points,
then you use the coordinate grid to plot the points and then draw the graph from the points that has been plotted.
Hopefully this helps :)
