Answer:
Step-by-step explanation:radius r = 4 m
height h = 13 m
slant height s = 13.6014705 m
volume V = 217.817091 m3
lateral surface area L = 170.921119 m2
base surface area B = 50.2654825 m2
total surface area A = 221.186602 m2
Answer:
(9, <u>81</u>) (<u>8</u>, 71)
Step-by-step explanation:
My explanation is in the picture. All I did was replace the known variable with the proper letter!
Just plug in a 0 to fine the x and y intercepts just like
2x0-3y=12 Now that would be 3y=12
y=4
So the y intercept is 4
then do the same to find x
Like 2x-3x0=12 That would be 2x=12
x=6
That is how you find x and y intercepts. Hope this helped
Begin with cos(θ) = 5/13, θ in Quadrant IV
you should distinguish the 5-12-13 right-angled triangle
and then cosØ = adjacent/hypotenuse
x = 5, r = 13 , y = -12, since Ø is in IV
and sinØ = -12/13
also tan(ϕ) = −√15 = -√15/1 = y/x and ϕ is in II,
y = √15 , x = -1
r^2 = x^2 + y^2 = 15+1 = 16
r = 4
sinϕ = √15/4 , cosϕ = -1/4
you must know that:
cos(θ − ϕ) = cosθcosϕ + sinθsinϕ
= (5/13)(-1/4) + (-12/13)(√15/4)
= -5/52 - 12√15/52
= (-5-12√15)/52
Answer:
BD bisects AC
Step-by-step explanation:
This statement is incorrect because the correct definition of bisect is dividing in equal parts and from my observation BD does NOT bisect AC.
