Find the length of an apothem of a square if the perimeter is 40.

1 answer:

8 0

An apothem of a square is a perpendicular from a center of a square to one of its side.

1. Put a dot at the center of the square. (You can find the center by drawing diagonals from corner to corner. The center is where they intersect).

2. Draw a perpendicular line in any of the four directions to one side of the square.

3. Two apothems of a square (drawn to opposite sides) make a line that is parallel to both (left) sides of the square, a line that is of equal length. If two apothems added together are equal to the length of one side, then one apothem is half of the length.

4. The square perimeter is 40 and it consists of 4 equal parts, then the length of square's side is 10.

5. Then the apothem has length 5.

Which expression is equivalent to i 233? a)1 b)–1 c)i d)–i

Aneli [31]

We have to find the value of the expression $i^{233}$

We know that the below values.

$i^2=-1\\i^4=1$

Hence, in order to find the value of the given expression, we can first rewrite it in terms of $i^4$

$i^{233}=(i^4)^{58}\cdot i$

Now, we know that $i^4=1$

Hence, we have

$i^{233}=(1)^{58}\cdot i$

$i^{233}=1\cdot i$

$i^{233}=i$

C is the correct option.

What is the area of ABC below? If necessary, round your answer to two decimal places.

irina [24]

Our goal is to find the area
area=1/2 times base times height
we know the height is 7.9 but what is the base?

use the pythagorean theorem twice
alrighty
so
remember for legs length a and b and hytponuse c in a right triangle
a²+b²=c²

we need AD and DC

so
AD²+7.9²=9.4²
AD=√25.95

DC²+7.9²=23.2²
DC=√475.83

so
AD+DC=base=(√25.95)+(√475.83)
area=1/2bh
area=1/2((√25.95)+(√475.83))(7.9)
area≈106.28518654591426812803776879893
round to 2 decimal places
area≈106.29 square units

(a) 127.5 is what percent of 51 ?

ExtremeBDS [4]

To solve this, you need to divide 127.5 by 51:
127.5/51 = 2.5
To find the percent, multiply 2.5 by 100:
2.5 x 100% = 250%
So 127.5 is 250% of 51
