Answer:

708meters

Step-by-step explanation:

Given data

Lenght = 274meters

Width= 80 meters

The expression for the perimeter is

P= 2L+2W

substitute

P= 2*274+ 2*80

P= 548+160

P= 708 meters

Hence the perimeter of the block is 708meters

Answer:

<em>An exponential function is a Mathematical function in form f (x) = ax</em><em>.</em>

<em>f(x) = ax</em>

Step-by-step explanation:

<em> where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.</em>

<em>NoTe</em><em>:</em><em> The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.</em>

Answer:

x=4

x=17.9

Step-by-step explanation:

For the first diagram.

cos(45°)=x/4√2

x=4√2cos(45°)

x=4

For the second diagram

tan(38°)=14/x

0.781=14/x

x=14/0.781=17.9

If you know please help me
MrRa [10]

Average rate of change of the function =\frac{75}{2}

Solution:

Given function: f(x)=5(2)^{x} from x = 1 to x = 5

Substitute x = 1 and x = 5 in f(x).

f(1)=5(2)^{1}=10

f(5)=5(2)^{5}=160

Let us find the average rate of change of the function.

Average rate of change

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

Here a = 1 and b = 5.

                     $=\frac{f(5)-f(1)}{5-1}

Substitute f(5) and f(1).

                     $=\frac{160-10}{4}

                     $=\frac{150}{4}

                     $=\frac{75}{2}

Average rate of change of the function =\frac{75}{2}
