Answer:

2n and  n + 1  are even if  n is odd.

20 * (10.3)*n   is even  if (10.3)n is odd.

Step-by-step explanation:

Are you talking about the expression  10.3n   or simply n ?

If n is an odd number then  n+1 is even

2*n is even

Answer:

22.34 {km}^{2}

Step-by-step explanation:

The area of a circle:

A = πr^{2}

The problem gives the diameter of a circle, which is equal to 2*r.

If 5 1/3 = 2*r, then the radius is (16/3)/2 = 8/3.

Plugging this into the area equation,

A = π*{{8/3}}^{2}

A = \frac{{64*π}}{9} or approximately 22.34 {km}^{2}

Please help, will grant brainliest if correct, need now!!
Mama L [17]

Answer:

- 7

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ - 5, - 2 ]

f(b) = f(- 2) = (- 2)² - 4 = 4 - 4 = 0

f(a) = f(- 5) = (- 5)² - 4 = 25 - 4 = 21, thus

average rate of change = \frac{0-21}{-2-(-5)} = \frac{-21}{3} = - 7

The linear equality represented by the graph as,\rm y > \frac{2}{3} x+3

<h3>What is the definition of inequality?</h3>

Inequality is a sort of equation in which the equal sign is missing. As we will see, inequality is defined as a statement regarding the relative magnitude of two claims.

The slope of the dashed line is found as;

\rm m = \frac{y_2-y_1}{x_2-x_1}  \\\\\ m = \frac{3-1}{0+3} \\\\ m= \frac{2}{3}

The slope-intercept form is;

y=mx+c

Substitute the obtained value;

\rm  y = \frac{2}{3}x+3

We are aware that the given line Is a dashed line, and everything to its left is shadowed.

Hence, the linear equality is represented by the graph as,\rm y > \frac{2}{3} x+3

vaieri [72.5K]

Step-by-step explanation:

This can be modeled by the equation f(x)=7+5x

Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22

If x=50 then f(50)=7+5(50)

f(50)=$257
