744 square inches octagon area
Nikolay [14]3 years ago

The 8 sides of the regular octagon are all the same length, so the perimeter of it is 8*(12.4 in) = 99.2 in.

The area of a regular polygon is half the product of the perimeter and the apothem.
  area = (1/2)(99.2 in)(15 in) = 744 in²

The area of the stop sign is 744 in².

Two more than a number is less than 14. 2 + n less-than-or-equal-to 14 2 + n less-than 14 2 + n greater-than-or-equal-to 14 2 +
statuscvo [17]

Answer:

x+2 < 14 | -2

x < 12

2+n <= 14 | -2

n <= 12

2+n < 14 | -2

n < 14

2+n >= 14 | -2

n >= 12

2+n > 14 | -2

n > 14

Is x + 10 a factor of the function f(x) = x3 − 75x + 250? Explain.
lord [1]
Okay, I worked it out and yes, it is a factor. Once you got x=-10, then you plug it into your formula. from there you can work it out like I did and get the answer. You can also input it into a scientific calcuator and figure it out that way. If you need any more help, go ahead and message me. Hope this helps. You can also but it into the box and divide it that way to find out. whichever way is better for you

HELP for (ii)…..how do we find a?
Mariana [72]

By using the information given on the graph, we can see that a = 3.

<h3>How to find the value of a?</h3>

Here we have an exponential of the form:

y = p*a^x

And by looking at the graph, it passes through (0, 4) and (2, 36), so we can write:

4 = p*a^0\\\\36 = p*a^2

From the first equation we get that p = 4, replacing that on the second one we get:

36 = 4*a^2\\\\36/4 = 9 = a^2\\\\\sqrt{9} = 3 = a

So we conclude that a = 3.
