Answer:

(a,c) ∪ (f, g)

Step-by-step explanation:

The function is:

concave down in the intervals: (a,c) and (f, g)

concave up in the intervals: (c, f) and (h, g)

Draw the slope of the tangent lines of several points on the curve,

if the slope increases, the segment is concave up

if the slope decreases, the segment is concave down.

the inequality |t-57|<7 describes the range of monthly average temperature, T, in Degrees Fahrenheit, for san Francisco, Cali

Y_Kistochka [10]

Solution is: $50\leq T\leq 64$ and it means, the minimum temperature is 50° Fahrenheit and the maximum temperature is 64° Fahrenheit.

Explanation

Given inequality is: $|T-57|\leq 7$

As this is absolute inequality, so we will get two different inequalities-- one for positive and another for negative. So.....

$T-57\leq 7\\ \\ T\leq 7+57\\ \\ T\leq 64$

and

$-(T-57)\leq 7\\ \\ -T+57\leq 7\\ \\ -T\leq 7-57\\ \\ -T\leq -50\\ \\ T\geq 50$

So, the final combined solution will be: $50\leq T\leq 64$

It means that the minimum temperature for San Francisco, California is 50° Fahrenheit and the maximum temperature is 64° Fahrenheit.

11) The measure of each interior angle of a regular 11-sided polygon is

Svet_ta [14]

Answer:

Step-by-step explanation:

Always , sum of exterior angle of any polygon = 360

sum of exterior angle of 11- sided polygon = 360

Measurement of an exterior angle of 11-sided polygon = 360/11

= 32.73

Measurement of an interior angle of 11-sided polygon = 180 - 32 8/11

= 180 - 32.73= 147.27
