Murljashka [212]

Answer:

a. 8.4 ft³

b. 4.44 ft × 2.44 ft × 0.78 ft

Step-by-step explanation:

a. <em>Maximum volume </em>

We are creating a box with dimensions

l    = 6 – 2x

w = 4 – 2x

h = x

V = lwh  = x(6 – 2x)(4 – 2x)

We must determine the value of x that makes V a maximum.

One way is to plot the function V = x(6 – 2x)(4 – 2x).

The maximum appears to be at about (0.78, 8.4).

Thus, the maximum volume is 8.4 ft³.

b.<em> Dimensions </em>

 l = 6 – 2 × 0.78 = 6 – 1.56 = 4.44 ft

w = 4 – 2 × 0.78 = 4 – 1.56 = 2.44 ft

                                         h = 0.78 ft

The box with maximum volume has dimensions 4.44 ft × 2.44 ft × 0.78 ft.

Solve each equation by factoring,<br>x² - 2x - 15 = 0​
valina [46]

Answer:

x=−3 or x=5

Step-by-step explanation:

x2−2x−15=0

Step 1: Factor left side of equation.

(x+3)(x−5)=0

Step 2: Set factors equal to 0.

x+3=0 or x−5=0

x=−3 or x=5

Consider the region bounded by 4y=x^2 and 2y=x.
gayaneshka [121]

Answer:

a) ⅓ units²

b) 4/15 pi units³

c) 2/3 pi units³

Step-by-step explanation:

4y = x²

2y = x

4y = (2y)²

4y = 4y²

4y² - 4y = 0

y(y-1) = 0

y = 0, 1

x = 0, 2

Area

Integrate: x²/4 - x/2

From 0 to 2

(x³/12 - x²/4)

(8/12 - 4/4) - 0

= -⅓

Area = ⅓

Volume:

Squares and then integrate

Integrate: [x²/4]² - [x/2]²

Integrate: x⁴/16 - x²/4

x⁵/80 - x³/12

Limits 0 to 2

(2⁵/80 - 2³/12) - 0

-4/15

Volume = 4/15 pi

About the x-axis

x² = 4y

x² = 4y²

Integrate the difference

Integrate: 4y² - 4y

4y³/3 - 2y²

Limits 0 to 1

(4/3 - 2) - 0

-2/3

Volume = ⅔ pi
