Sorry if im wrong but i am pretty sure that is 266
Answer:
d is the answer
Step-by-step explanation:
just read the statements properly
I am assuming you mean 4/7 as the sine or cosine cannot be higher than 1.
Lets find <span>θ,
</span>
θ = [sin-1](4/7) = 34.85 °
But lets take into account that this value is the equivalent in Quadrant I.
If Θ lies in Quadrant II , then θ = 180 ° - 34.85 ° = 145.15 °
So cosθ = cos (145.15) = -0.821
Answer:
haiii i can only solve for the vertex...
Step-by-step explanation:
so to find the vertex you have to make it to
y - h = a(x - k)^2
i think
(you could also just make it y = a(x - k)^2 + h but i like the second one better)
soo
y + 5 = 3(x + 7)^2
the vertex is
(-7, -5)
and ummm i think the axis for the axis of symmetry .ss
x = 2a/b but im not sure
Answer:
Yes
Step-by-step explanation:
Since the longest side is 6.5 cm, so let it be hypotenuse c.
Verifying by right angle formula
c^2=a^2+b^2
(6.5)^2=(3.9)^2+(5.2)^2
42.25=15.21+27.04
42.25=42.25
Hence the given triangle is a right angles triangle
