The degree of the equation is 12 which means it's even. The leading coefficient is 7 which means it's positive. According to the these, the end behavior of the graph is:

<span><span>f<span>(x)</span>→+∞, as x→−∞
As x approaches negative infinity, the value of f(x) approached positive infinity

</span><span>f<span>(x)</span>→+∞, as x→+<span>∞
</span></span></span><span>As x approaches positive infinity, the value of f(x) approached positive infinity</span>

Option C:

The value of x is 27.

Solution:

Given exterior angles are 56°, 2x°, 85°, 57° and 4x°.

<em>Sum of exterior angles of a polygon = 360°</em>

⇒ 56° + 2x° + 85° + 57° + 4x° = 360°

⇒ 198° + 6x° = 360°

Subtract 198° from both sides of the equation.

⇒ 6x° = 162°

Divide by 6 on both sides, we get

⇒ x° = 27°

⇒ x = 27

The value of x is 27.

Option C is the correct answer.

Why is (-3,6] a better answer than (-3,6)

Pani-rosa [81]

(-3, 6) includes all numbers between -3 and 6 but it does not include -3 and 6.

when you put square parentheses you include the number on the edge

so if an anwser includes all numbers between -3 and 6 and the number 6 it's correct to write (-3,6]

The day's high temperature in St. Louis comma Missouri was recorded as 77 degrees' F. Use the formula Upper C=5/9(F-32) to writ

ludmilkaskok [199]

Answer:

The day's high temperature written as degrees Celsius is 25 degrees' Celsius.

Step-by-step explanation:

The day's high temperature in St. Louis ,Missouri was recorded as 77 degrees F.

We are supposed to find the day's high temperature written as degrees Celsius.

Formula : $C=\frac{5}{9}(F-32)$

Substitute the value of F is 77 degrees

So, $C=\frac{5}{9}(77-32)$

$C=\frac{5}{9}(45)$

C=25

Thus, The day's high temperature written as degrees Celsius is 25 degrees' Celsius.
