Hi there!

»»————-　★　————-««

I believe your answer is:

The square root of 5 ( $\sqrt{5}$ ) is irrational.

»»————-　★　————-««

Here’s why:

A rational number is a number that can be rewritten as a fraction of two integers with a nonzero denominator.

Rational numbers include integers, fractions, terminating decimal, or repeating decimals.
A square root that is perfect would be rational. A non-perfect square root is irrational.

⸻⸻⸻⸻

Since the square root of 5 is not a perfect square, it would be irrational.

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

artcher [175]

ANSWER

EXPLANATION

The revenue function is

$r = - 50 {t}^{2} + 300t$

The cost function is,

C=600-50t

In order to break even, revenue must be equal to cost.

$600 - 50t= -50 {t}^{2} + 300t$

Group every term on the LHS.

$50 {t}^{2} - 300t - 50t + 600 = 0$

$50{t}^{2} - 350t + 600 = 0$

Divide through by 50.

${t}^{2} - 7t + 12= 0$

Factor to obtain,

$(t - 3)(t - 4) = 0$

$t = 3 \: or \: t = 4$

Select the correct answer from each drop-down menu

Yakvenalex [24]

Answer:

First row. = -393 74 287

Second row = 471. 162 91

Third row =251 222 - 349

Step-by-step explanation:

For the first row

Cofactor of 12= (-8*15)-(21*13)

= -120-273

= -393

Cofactor of 23 = (11*15)-(7*13)

= 165-91

= 74

Cofactor of -6 = (11*21)-(-7*8)

= 231+56

= 287

For the second row

Cofactor of 11 = (23*15)-(21*-6)

= 345+126

= 471

Cofactor of -8 = (12*15)-(7*-6)

= 120 + 42

= 162

Cofactor of 13 (12*21)-(23*7)

= 252-161

= 91

For third row

Cofactor of 7= (23*13)-(-8*-6)

= 299-48

= 251

Cofactor of 21 = (12*13)-(11*-6)

= 156+66

=222

Cofactor of 15 = (12*-8)-(11*23)

= -96 - 253

=- 349
