Which statements are true for the functions g(x) = x2 and h(x) = –x2 ?

svp [43]

Answer:

g(x) > h(x) for x = -1.

For positive values of x, g(x) > h(x).

For negative values of x, g(x) > h(x).

If 30,000 cm2 of material is available to make a box with a square base and an open top, find the largest possible volume of the

Ilya [14]

Answer:

The largest possible volume of the box is 500,000 cm³

Step-by-step explanation:

Let the a side of the square base = x

let the height of the box, = h

volume of the box, v = hx²

Surface area of the box, A = 4hx + x²

30000 = 4hx + x²

make h the subject of the formula;

$4hx + x^2 = 30000\\\\4hx = 30000 -x^2\\\\h = \frac{30000 -x^2}{4x}$

Volume of the box, V = hx²

$V = h*x^2 = (\frac{30000-x^2}{4x} )x^2\\\\V = \frac{30000x^2 -x^4}{4x} \\\\V = \frac{30000x^2}{4x} - \frac{x^4}{4x} \\\\V = 7500x- \frac{x^3}{4}$

At maximum value of V, dv/dx = 0

$\frac{dv}{dx} = 7500 - \frac{3}{4} x^2\\\\0 = 7500 - \frac{3}{4} x^2\\\\\frac{3}{4} x^2 = 7500\\\\x^2 = 10000\\\\x = \sqrt{10000} \\\\x = 100$

Substitute in the value of x to determine the maximum volume, V;

$V = 7500x - \frac{x^3}{4} \\\\V = 7500(100) - \frac{1}{4} (100)^3\\\\V = 750000- 250000\\\\V = 500,000 \ cm^3$

Therefore, the largest possible volume of the box is 500,000 cm³

I need help with this what would k be? Or is she correct

charle [14.2K]

Answer:

The value of k=1

So, Maura claim is incorrect. The value of k=1 and not k=1/2

Step-by-step explanation:

We need to determine the value of k if $2^4=16^k$

We are given:

$2^4=16^k$

Exponent rule, if bases are equal the exponents are equal

We can write $16= 2^4$

$2^4=(2^4)^k\\2^4=2^{4k}$

Now since the base is same, i,e 2 so, the exponents will be same

$4=4k\\k=1$

So, the value of k=1

So, Maura claim is incorrect. The value of k=1 and not k=1/2
