Answer:
3=a(-3-(-2))^2+2
Step-by-step explanation:
The length of the ladder is approximately 3 m. The correct option is the first option 3
<h3>Calculating the length of a ladder</h3>
From the question, we are to calculate the length of the ladder.
From the given information,
The ladder makes an angle 20° with the ground
and
The foot of the ladder is 3 m from the wall
This scenario gives a right triangle where the hypotenuse is the ladder and the adjacent is the distance of the foot of the ladder from the wall.
Let the length of the ladder be x
Thus,
Using SOH CAH TOA
We can write that
cos 20° = 3 / x
x = 3/(cos 20°)
x = 3.19
x ≈ 3 m
Hence, the length is approximately 3 m

not possible because the area of a square is always a square of it's length and a square cannot be a prime number
Answer:
-2/-3
Step-by-step explanation:
Because -2/-3=2/3.
Answer:
Step-by-step explanation:
we would like to solve the following trigonometric equation:
the left hand side can be rewritten using <u>angle </u><u>sum </u><u>indentity</u><u> </u><u>of </u><u>sin </u>which is given by:
therefore Let
Thus substitute:
simplify addition:
keep in mind that <u>sin(</u><u>t)</u><u>=</u><u>sin(</u><u>π-t)</u><u> </u>saying that there're two equation to solve:
take inverse trig and that yields:
add π to both sides of the second equation and that yields:
sin function has a period of <u>2</u><u>n</u><u>π</u><u> </u>thus add the period:
divide I equation by 4 and II by -4 which yields:
recall that,<u>-</u><u>½</u><u>(</u><u>nπ)</u><u>=</u><u>½</u><u>(</u><u>nπ)</u><u> </u>therefore,
by using a calculator we acquire:
hence,
the general solution for: for the trig equation are
