Find a formula for the described function. An open rectangular box with volume 3 m3 has a square base. Express the surface area
Alex73 [517]

Answer:

SA(x) = x^2 + \frac{12}{x}

Step-by-step explanation:

Given

V = 3m^3 --- volume

x \to base\ length

y \to height

Required

The surface area as a function of base length

The volume (V) is calculated as:

V = Base\ Area * Height

V = x*x*y

V = x^2*y

Make y the subject

y = \frac{V}{x^2}

Substitute 3 for V

y = \frac{3}{x^2}

The surface area of the open box is:

SA = x^2 + 2xy+2xy

SA = x^2 + 4xy

Substitute: y = \frac{3}{x^2}

SA = x^2 + 4x*\frac{3}{x^2}

SA = x^2 + 4*\frac{3}{x}

SA = x^2 + \frac{12}{x}

Hence, the function is:

SA(x) = x^2 + \frac{12}{x}

The ratio of angle measures is 1:2:2. Classify the triangle by its angle measures. a.acute triangle b.right triangle c. obtuse t
HACTEHA [7]
Angles in a triangle must add up to 180°, so you could use this information to find the values of the angles. 1 + 2 + 2 = 5, 180 ÷ 5 = 36. 36 × 2 = 72, so 36 + 72 + 72 = 180. This means that the answer is A. acute, because all of the angles are below 90°. I hope this helps!

The value of the fractions will be:

1. 8 13/20

2. 2 4/5

3. 5/6

<h3>How to explain the fraction?</h3>

1. 6 1/4 + 2 2/5

LCM of 20

6 1/4 + 2 2/5.

6 5/20 + 2 8/20

= 8 13/20

2. 1 1/5 × 2 1/3

= 6/5 × 7/3

= 42/15

= 14/5

= 2 4/5

3. 3 1/3 - 2 1/2

= 3 2/6 - 2 3/6.

= 5/6
