A company is constructing an open-top, square-based, rectangular metal tank that will have a volume of 49 cubic feet. What dime

yawa3891 [41]

Answer:

b = 4.6 ft

h = 2.3 ft

Step-by-step explanation:

The volume of the tank is given by:

$b^2*h=49$

Where 'b' is the length of the each side of the square base, and 'h' is the height of the tank.

The surface area can be written as:

$A=b^2+4bh\\A=b^2+4b*({\frac{49}{b^2}})\\A=b^2+\frac{196}{b}$

The value of b for which the derivate of the expression above is zero is the value that yields the minimum surface area:

$\frac{dA}{db} =0=2b-\frac{196}{b^2}\\2b^3=196\\b=4.61\ ft$

The value of h is then:

$h=\frac{49}{4.61^2}\\h=2.31\ ft$

Rounded to the nearest tenth, the dimensions are b = 4.6 ft and h = 2.3 ft.

PLEASE HURRY WILL GIVE BRAINLIEST <br> What is the solution of

ANTONII [103]

Answer:

Option A

Step-by-step explanation:

<u>Find zeros first:</u>

x² + x - 6 = x² + 3x - 2x - 6 = x(x + 3) - 2(x + 3) = (x - 2)(x + 3)
x = 2, x = -3, x = 7 (but x ≠ 7 as no division by zero)

<u>We have 4 intervals:</u>

x ≤ - 3, three negatives, the result is negative or zero
-3 ≤ x ≤ 2, two negatives and one positive, the result is positive or zero
2 ≤ x < 7, two positives and one negative, the result is negative or zero
x > 7, three positives, the result is positive or zero

<u>The solution is:</u>

x ≤ - 3 or 2 ≤ x < 7

Correct choice is A

Jenna is driving 400 miles to visit her grandmother. She managesto travel the first 100 miles of her trip in two hours. Is she c

dalvyx [7]

Answer:

Jenna will complete remaining distance in 6 hours.

Step-by-step explanation:

Since we know that $\text{Speed}=\frac{\text{Distance}}{\text{Time}}$ . Let us find the rate at which Jenna traveled 100 miles.

$\text{Speed}=\frac{100\text{ miles}}{2\text{ hours}}$

$\text{Speed}=50\frac{\text{ miles}}{\text{ hours}}$

Remaining distance is 400-100=300.

Now let us find the time Jenna will take to travel 300 miles.

$\text{Time}=\frac{300}{50}$

$\text{Time}=6$

Therefore, Jenna took 6 hours to complete remaining distance.
