Answer:
Equation: y = 2(x^2)
Y-value = 32
X-value = 10
Step-by-step explanation:
y = k(x^2)
<em>k symbolises proportionality</em>.
solve for k:
50 = k(5^2)
50 = 25k
k =2
So...
<em>equation is y = 2(x^2)</em>
Value of y when x = 4,
y = 2 x 4^2
y = 2 x16
y = 32
Value of x when y = 200,
200 = 2(x^2)
100 = x^2
x = 10
Answer:
3x+3x=6x+7=13+4x=17+5=22-8=17
Step-by-step explanation:
Just add them all and minus

The correct answer is option D which is the function is even because of its symmetry about the y-axis.
<h3>What is even function?</h3>
The function which remains unchanged when the negative value of the variable is filled in the function is called an even function and this function is symmetric about the y-axis.
Given function:-
f(x) = 3x⁴+2x²
Now put the value x = -x in the function
f(-x) = 3( -x⁴)+2(-x²)
f(-x) = 3x⁴ + 2x²
f(-x) = f(x)
here we can see that when we put the value of negative x the function remains unchanged.
Therefore the correct answer is option D which is the function is even because of its symmetry about the y-axis.

The answer will be 62.4. We know this because of the next procedure:
<span>We know that:
the volume of a cylinder is pi * r^2 * h
the volume of a cone is 1/3 * pi * r^2 * h
the total height is 47.
the height of the cone is 12.
</span><span>the height of the cylinder must be 35.
Now, if the top half is filled with sand, then the volume of the sand is
pi * 4^2 * 36 and the volume of the cone is 1/3 * pi * 4^2 * 12.
the total volume = 1960.353816 cubic millimeters.
since the top drains at the rate of 10 * pi cubic millimeters per second, the top will be empty and the bottom full after 1960.353816 / (10 * pi) = 62.4 seconds.
I hope this answer is ok for you </span>
