For the graph shown, select the statement that best represents the given system of equations. Number graph ranging from negative

seven to eight on the x and y axes. A line is drawn on the graph that crosses the x axis at (negative three, zero) and crosses the y axis at (zero, five). A second line is drawn on the graph, which crosses the y axis at (zero, three) and crosses the x axis at (four, zero). 2y – 3x = 9 4y + 3x = 12 A. coincident B. inconsistent C. consistent and independent D. not enough information

Y is directly proportional to x² and y = 50 when x =5, Find
san4es73 [151]

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

Which statement is true about the function?​
ohaa [14]

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.

An hourglass consists of two sets of congruent composite figures on either end. Each composite figure is made up of a cone and a
Elena-2011 [213]
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>
