Answer:

164 square inches

Step-by-step explanation:

You can compute the area by adding the areas of the 4 corner triangles, the 4 side rectangles and the central square.

The area of the triangle is ...

A = (1/2)bh = (1/2)(4 in)(4 in) = 8 in²

The area of a rectangle is ...

A = LW = (6 in)(4 in) = 24 in²

The area of the central square is ...

A = s² = (6 in)² = 36 in²

Then the total area is ...

4(8 in²) +4(24 in²) +36 in² = (32 +96 +36) in² = 164 in²

Alternatively, you can draw a 14-inch square around the whole figure, then subtract the areas of the four corner triangles that are not part of the octagon. The area computed that way would be ...

(14 in)² - 4((1/2)(4 in)(4 in)) = 196 in² -32 in² = 164 in²

Which of the following points lies on the graph of the function y= 2.3*?

Rainbow [258]

If the equation is $y = 2\cdot 3^x$ (2 times 3^x)

Then the answer is d. (0,2)

This is because plugging x = 0 leads to y = 2 as shown below

$y = 2\cdot 3^x\\\\y = 2\cdot 3^0\\\\y = 2\cdot 1\\\\y = 2$

Waterloo Park posted the following schedule listing the number of hours an employee works on a given day. Let B(x), T(x), R(x),

Advocard [28]

From the table, we observe that the domain of the function is {Mon, Tues, Wed, Thurs, Fri} and the range is {1, 2, 3, 4, 0}

So, S(Mon) = 1

S(Tues) = 2

S(Wed) = 3

S(Thurs) = 4

S(Fri) = 0

Hence, $S^{- 1}(0) = Friday$

How do I solve 5x - 4 = -19

ira [324]

Undo what has been done to the variable. That means to do the opposite done to the variable.
5x-4=-19
+4=+4
5x=-15
5 is being multiplied to the variable so you divide it from both sides.
x=-3
