const2013 [10]

hello!

so the difference is 101 and here is why!

you want to minus -1 from 100

100 - (-1)

How to write two different pairs of decimals whose sums are 14.1. One pair should involve regrouping
Nitella [24]
To solve, first let’s define regrouping:<span>
<span>=> Regrouping involves carrying and borrowing during subtraction and addition of the given numbers.

So let us have the non-regrouping decimal number: 
=> 8.4
Next, the other regrouping decimal 
=> 5.7

So now let us show how it becomes 14.1:
  8.4
+5.7
14.1

Starting from the right, 4 + 7 is equal 11, so bring down 1 and carry 1. Now 8+5 = 13, but 13 + carry 1 = 14
<span>Thus, the answer is 14.1</span></span></span>

If x = 4cosa and y = 5tana, find (x^2/16) - (y^2/25)​
Cloud [144]

x = 4 \cos(a)

\frac{x}{4}  =  \cos(a)  \\

( { \frac{x}{4} })^{2}  =  ({ \cos(a) })^{2}  \\

\frac{ {x}^{2} }{16}  =  {cos}^{2} (a) \\

_____________________________________________

y = 5 \tan(a)

\frac{y}{5}  =  \tan(a)  \\

( { \frac{y}{5} })^{2}  = ( { \tan(a) })^{2}  \\

\frac{ {y}^{2} }{25}  =  {tan}^{2} (a) \\

_____________________________________________

Thus ;

\frac{ {x}^{2} }{16}  -  \frac{ {y}^{2} }{25}  =  \\

{cos}^{2} (a) -  {tan}^{2} (a)
