Answer:
2x²√13
Step-by-step explanation:
√52x⁴ = √4×13×x⁴ = 2x²√13
I'll do better than that ! I'll show you how to do it, because
the answer is no help if you don;t know how to work it out.
Do you see that little square in one corner of the triangle ? That tells you
that the angle there is 90 degrees, and THAT tells you that the triangle is
a RIGHT triangle. This is a very helpful piece of information, because there's
a rule about the sides of a right triangle that isn't true for any other kind of triangle. The rule is:
(the longest side)² = (one of the other sides)² plus (the third side)²
Also, the longest side is always the one that doesn't touch the 90-degree angle.
In this triangle in the picture,
-- the longest side is 'A' ... it's 13 .
-- one of the other sides is ' b ' ... it's 12 .
-- the third side is ' C ' ... the one you have to find.
Using the formula up above, you know that
(13)² = (12)² + C²
Before you go to work on it, subtract (12)² from each side of this equation,
just to make it a little easier, and then you have
<em> C² = (13)² minus (12)²</em>
And right there is how to figure out the length of ' C '.
I'll give you even more information to help you, and then it's up to you
to finish it and get the answer. Here it is:
(13)² = 169
(12)² = 144
Now you have everything you need. Go to it !
Answer:
$9,945
Step-by-step explanation:
Principal = $8,500
Rate = 17% = 0.17
Number of times compounded in a year, n = 1
Period, t = 1 year
Amount, A = P(1 + r/n)^tn
A = 8500( 1 + 0.17/1)^ 1*1
A = 8500( 1.17)^1
A = $9,945
162 short sleeve shirts; if you add 9 and 4, you get 13. Then, divide 234 by 13, which equals 18. 18 multiplied by 9 is 162.
