Sin(x) = opposite over hypotenuse
Cos(x) = adjacent over hypotenuse
Tan(x) = opposite over adjacent
Everything revolves around a right triangle.
From the given equation, "<span>sine of x equals square root of 2 over 2"
Opposite = square root of 2
Hypotenuse = 2
Adjacent = ?
Using the Pythagorean Equation: H^2 = O^2 + A^2
2^2 = (square root of 2)^2 + A^2
A^2 = 4 - 2
A = square root of 2
Cos(x) = square root of 2 over 2
Tan(x) = square root of 2 over square root of 2 = 1</span>
Answer:
2 4/25
Step-by-step explanation:
<u>2.16</u> as a fraction = 2 16/100
simplify 16/100by dividing both parts by 4 to obtain 4/25
Hence the answer is 2 4/25
y≤ 3 when x is 0 and x≤ 3 when y is 0
The graph is attached in figure below
Step-by-step explanation:
We need to graph x+y is equal or less than 3
Writing in mathematical form:
For solving we find x and y intercepts
The y-intercept can be found by putting x=0, y is :
y≤ 3 when x is 0
The x-intercept can be found by putting y=0, x is :
x≤ 3 when y is 0
Plotting these values on the graph:
The graph is attached in figure below

Answer: y=-6
Step-by-step explanation:
y = -4 when x = 1
find y when x = 3
y=-4 x=1
y=-5 x=2
y=-6 x=3
im not sure if this is right so I’m sorry
