So using the formula for the volume of a cone:
r^2pi x h/3
The height is always 4 times the radius, so:
h=4r
Now putting the values into the original formula:
r^2pi x 4r/3
Now to see how much the radius increases per second:
r^2pi x 4r/3=300pi
r^2 x 4r/3=300
r^2 x 4r=900
r^2 x r=225
r^3=225
The radius increases by the cubic square root of 225 cm per second.
f(s)= 225^1/3 cm
Answer:
-23
Step-by-step explanation:
We are given the functions;
h(x) = 5x - 3 and j(x) = -2x
Now, we want to find h[j(2)]
j(2) = -2(2)
j(2) = -4
Thus;
h(-4) = 5(-4) - 3
h(-4) = -20 - 3
h(-4) = - 23
Answer:
<h2>By angle sum property:</h2>
BAC+ABC+BCA=180°
90°+45°+x=180°
135°+x=180°
x=45°=BCA
<h2>since BCA=ABC=<u> </u>45° each </h2><h2>therefore,</h2>

I believe it is D, stratified random sampling.
Hope this helps!!
Answer:
(146 + 0i)
Step-by-step explanation:
(11+5i)(11-5i)
The formula is :
(a+bi) • (x+yi) = ax+by•i^2+(ay+bx)i
and since i^2 = -1 it can be written as :
ax - by + (ay + bx) i
( 11 + 5i) • ( 11 - 5i) =
(146 + 0i)
hope this helped brainlest owo???
