Answer: 72,910

Step By Step Explaination:  7.291 x 10^4

10^4 means to move the decimal places four times.

The perimeter of the rectangle below is 174 units. Find the length of side BC. Write your answer without variables.
hodyreva [135]
BC= 39



Explanation:


4z+4z+3z+3+3z+3=174

8z+6z+6=174

14z+6=174

Subtract 6 from both sides

14z=168

Z=12


So then 3*12+3=39


And you can check by doing 39+39+48+48
And it equals 174

Which graph represents the function f(x)= 0.2^x + 3
Dennis_Churaev [7]

The third graph or bottom left graph represents f(x) = 0.2^{x} + 3.

Step-by-step explanation:

Step 1:

To determine which of the given graphs represents the equation f(x) = 0.2^{x} + 3, we substitute some values in the place of x.

When x=0, f(x) = 0.2^{x} + 3, f(0) = 0.2^{0} + 3= 4.

Anything with an exponent of 0 will equal 1.

So the graphs on the right side cannot be the answers.

Step 2:

Now we substitute another value to determine which graph represents f(x) = 0.2^{x} + 3.

When x=1, f(x) = 0.2^{x} + 3, f(1) = 0.2^{1} + 3= 4.2.

The value of f(x) when x=1 is lesser than the value of f(x) when x =0.

So the third graph or bottom left graph represents f(x) = 0.2^{x} + 3.
