Idk I’m sorry I would love too help you
f(x, y) = 4x + 7y - 6
substitute x=5 and y=-5
f(5,-5) = 4(5) + 7(-5) - 6
f(5,-5) =20-35-6
= -15-6
=-21
We have that
3 = 3 + 0i -----------> rewrite as 3(1 + 0i)
<span>So now what we have to do is figure out which of the above expressions has cos a = 1 and sin a = 0. </span>
<span>cos 0 = 1, and sin 0 = 0, so that's the answer that we want.
</span><span>the answer is: </span>
3 = 3(cos 0 + i sin 0)
Answer:
Answer:574.9ft^3.
Step-by-step explanation:
radius (r) = 6.5feet
π=3.14
volume of hemisphere=2/3 x π x r^3
Volume=2/3 x 3.14 x (6.5) ^3
Volume=2/3 x 3.14 x 6.5 x 6.5 x 6.5
Volume = (2x3.14x6.5x6.5x6.5) ➗ 3
Volume=1724.645 ➗ 3
Volume=574.9ft^3
