Answer:
the answer is (2,-6)
Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
p(x)=sin(x) is an odd function since sin(-x)=-sin(x).
q(x)=cos(x) is an even function since cos(-x)=cos(x).
r(x)=tan(x) is an odd function since tan(-x)=-tan(x).
s(x)=csc(x) is an odd function since csc(-x)=-csc(x).
So the only contender seems to be C.
Let's check. To check we have to plug in (-x) in place of (x) and see if we get the same function back since we are looking for an even function.
Replace (x) with (-x):
since cosine is even; that is cos(-u)=cos(u) where u in this case is .
So f is even.
Answer:
125.97
Step-by-step explanation:
We’ll start by the cone
We first have to know how to calculate the volume of a cone
V = pi(r^2)(h)/3 where r = radius & h = height
But since we’re only seeing a diameter of 6 cm in the bottom of the cone, we’ll need to divided 6 by 2
Radius = 3
Then we can start solving for the volume of the cone!
V = pi(3^2)(7)/3
V = pi(9)(7)/3
V = pi(63)/3
V = 197.82…/3
V = 65.97
The volume of the cone is approximately 66 cm
Now for the Rectangular Prism:
V = l • w • h where l = length w = width and h = height
V = 12 • 5 • 1
V = 60 • 1
V = 60
Finally add each of the volumes!
65.97 + 60 = 125.97
The volume of the object is approximately 126 cm
Answer:
y < -12

Answer:
2hr 48 minutes
Step-by-step explanation:
65t + 85t = 420
150t = 420
t = 2 120/150 = 2 4/5 = 2hr 48 minutes
