<span> f(-4) all you need to do is plug in x = -4 into equation
so </span><span>If f(x)=-8-5x then
f(-4) = -8 - 5(-4)
f(-4) = -8 + 20
f(-4) = 12
answer
f(-4) = 12</span>
Answer:
Step-by-step explanation:
the formula for Volume of the sphere is
V=4/3 * π*r^3
diameter =4, r=2
V=4/3 * 3.14 * 8=33.49
Answer:
Step-by-step explanation:
To do this, we must use the unit circle. At the angle 
the coordinate pair is (
, 
) and the hypotenuse is 1
Now that we know these we can start using the trig functions
sin = y
cos = x
tan = 
And the other functions would be the reciprocal of these
csc = 
sec = 
cot = 
This would mean that
sinx =
cosx =
tanx =
or 
if you're supposed to rationalize your denominators
cscx = 2
secx = 
or 
cot = 
Answer:
Step-by-step explanation:
(-2,2) ...x1 = -2 and y1 = 2
(4,6)..x2 = 4 and y2 = 6
midpoint formula :
m = ((x1 + x2) / 2 , (y1 + y2) / 2)
m = ((-2 + 4) / 2 , (2 + 6) / 2)
m = 2/2 , 8/2
m = (1,4) <===
