Answer:

Step-by-step explanation:

The tuna can has a shape of a cylinder, and the area of the tuna lablel is the lateral surface area of the can

$A=2\pi rh$

Data

diameter d= 6.5cm

radius r = $\frac{diameter}{2}$ = $\frac{6.5}{2} = 3.25cm$

height h= 3cm

leteral surface area

$A=2*3.142*3.25*3\\= 61.269\\=61.27cm^2$

2x-5=3x^2 find the root of X

Zina [86]

For this case we must solve the following quadratic equation:

$3x ^ 2-2x + 5 = 0$

Where:

$a = 3\\b = -2\\c = 5$

The roots are given by:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Substituting the values we have:

$x = \frac {- (- 2) \pm \sqrt {(- 2) ^ 2-4 (3) (5)}} {2 (3)}\\x = \frac {- (- 2) \pm \sqrt {(- 2) ^ 2-4 (3) (5)}} {2 (3)}\\x = \frac {2 \pm \sqrt {4-60}} {6}\\x = \frac {2 \pm \sqrt {-56}} {6}$

By definition we have to:

$i ^ 2 = -1\\x = \frac {2 \pm \sqrt {56i ^ 2}} {6}\\x = \frac {2 \pm i \sqrt {56}} {6}\\x = \frac {2 \pm i \sqrt {2 ^ 2 * 14}} {6}\\x = \frac {2 \pm 2i \sqrt {14}} {6}\\x = \frac {1 \pm i \sqrt {14}} {3}$

We have two complex roots:

$x_ {1} = \frac {1+ i \sqrt {14}} {3}\\x_ {2} = \frac {1- i \sqrt {14}} {3}$

Answer:

$x_ {1} = \frac {1+ i \sqrt {14}} {3}\\x_ {2} = \frac {1- i \sqrt {14}} {3}$

Simplify (Cot t) (Sin t)/(Cos t)

Serhud [2]

Answer:

Step-by-step explanation:

(Cot t) (Sin t)/(Cos t)

cot = cos / sin

Replacing cot t with cos t / sin t

cos t/ sin t * (Sin t)/(Cos t)

Canceling the sin t's

cos t / cos t

What's the degree of the polynomial? P(x)= 7x^7+2x^5+7x+7

mario62 [17]

Answer:

General Formulas and Concepts:

Degree of Polynomial is determined by the highest power

Step-by-step explanation:

<u>Step 1: Define function</u>

P(x) = 7x⁷ + 2x⁵ + 7x + 7

<u>Step 2: Identify</u>

7x⁷ is the largest term.

Has the highest power
Therefore, highest degree
