Answer:
(0,1) and (-2,9)
Step-by-step explanation:
A point (x,y) lies on the graph of f(x) = 
if it satisfies the condition y =
<h3>
(0,1):</h3>
x = 0 and y = 1.
This point satisfies the required condition as
= 1
Hence, this point <u>is</u> on the graph of f(x) =
<h3>
(3,27):</h3>
x = 3 and y = 27.
This point doesn't satisfy the required condition as
= 
≠ 27
Hence, this point i<u>s not</u> on the graph of f(x) =
<h3>
(-2,9):</h3>
x = -2 and y = 9.
This point satisfies the required condition as
= 
= 9
Hence, this point <u>is</u> on the graph of f(x) =
<h3>
(-1,
):</h3>
x = -1 and y = .
This point satisfies the required condition as
y = 
= 
= 3 ≠
Hence, this point <u>is not</u> on the graph of f(x) =
Answer:
25.5
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships between angles and sides and trig functions in a right triangle. Here, the side adjacent and the side opposite the marked angle are also marked. That means the relevant trig relation is ...
Tan = Opposite/Adjacent
tan(49°) = x/(22.2 m)
Multiplying by the denominator, we get ...
x = (22.2 m)tan(49°) ≈ 25.5 m
The unknown side is about 25.5 meters.
Answer:
How to choose which trig function to use based on an angle? I'm assuming that's simpler form of the question hehe
Step-by-step explanation:
pick an angle, and look at the sides that you HAVE
if you have the side opposite to the angle, and the hypotenuse of the triangle you use sine.
if you have the side adjacent to said angle, and the hypotenuse, you use cosine.
and if you don't have the hypotenuse, but you have the other two sides, you use tangent.
Answer:
n = 2.5
Step-by-step explanation:
distribute
-20n + 12 + 2.6 + 12n = -5.4
combine terms
-8n + 14.6 = -5.4
subtract 14.6 from both sides
-8n = -20
divide by -8
n = 2.5
Well, the answer is Rhombus. Hope I help you ;)
