Answer:

Step-by-step explanation:

Given

square bottom area is 24\times 24\ in.^2

Suppose x in. is cut from each corner to make a open box with maximum volume

New base area is (24-x)\times (24-x) in.^2

Volume of box

V=(24-x)^2\times x

Differentiate V w.r.t x to get maximum volume

\frac{\mathrm{d} V}{\mathrm{d} x}=2\cdot (24-x)(-1)+1\cdot (24-x)^2

Put \frac{\mathrm{d} V}{\mathrm{d} x}=0

\left ( 24-x\right )\left [ -2x+24-x\right ]=0

\left ( 24-x\right )\left [ 24-3x\right ]=0

x=24,8

but x=24 is not possible therefore x=8 will yield maximum volume

V=(24-8)^2\cdot 8=2048\ in.^2

Solve the following quadratic equation by rearranging and then factorising x^2 + 3x - 15 = 2x - 13
NNADVOKAT [17]

Step-by-step explanation:

x² + 3x - 15 = 2x - 13

x² + x - 2 = 0

(x + 2)(x - 1) = 0

By zero product rule, (x + 2) = 0 or (x - 1) = 0.

Hence x = -2 or x = 1.

OleMash [197]
Well if he is filling one 3/4 quart bottle, then he must fill his measuring cup 3 times, so just multiply it by 5, and you have 15.

David needs to fill the measuring cup 15 times.

Given f(x) = 4x^2 + 19x - 5 and g(x) = 4x^2 - x what is (f/g)(x)?
Free_Kalibri [48]

( \frac{f}{g} )(x) =  \frac{4 {x}^{2}  + 19x - 5}{4 {x}^{2}  - x}  =  \frac{(4x - 1)(x + 5)}{x(4x - 1)}  =  \frac{x + 5}{x}
