C^2 = a^2 + b^2
4^2 = 2^2 + b^2
b^2 = 4^2 - 2^2
b^2 = 16 - 4
b^2 = 12
b = square root of 12
b = square root of 4 x square root of 3
b = 2 x square root of 3

A = 2
B = 2 x square root of 3
C = 4

Step-by-step explanation:

By Question :-

Sum of numbers = 90 .
Difference of numbers = 18 .

Let :-

First Number be x .
Second number be y .

According to 1st condition :-

$: \implies$ x + y = 90

According to 2nd condition :-

$: \implies$ x - y = 18

Adding the equations :-

$: \implies$ 2x = 18 + 90

$: \implies$ 2x = 108

$: \implies$ x = 54

Therefore :-

$: \implies$ First number = 54

$: \implies$ Second number = 36

For a pair (x,y)

x is domain and y is range

So here

The end points

(0,9)
(8,1)

Hence domain

In May, Liam and Charlie had the same amount of money in their savings accounts. In June, Liam deposited $140 into his account.

romanna [79]

Let's say both had an original amount of "a".

then Liam deposited 140, so it became a + 140.

then Charlie added 5% of "a" to "a", well, 5% of anything is just (5/100)*anything, so 5% of "a" is just (5/100) *a or 0.05a.

then they checked their amounts and both were equal, what the? let's check.

$\bf \stackrel{\textit{Liam}}{a+140}=\stackrel{\textit{Charlie}}{a+0.05a}\implies a+140=1.05a\implies 140=1.05a-a
\\\\\\
140=0.05a\implies \cfrac{140}{0.05}=a\implies \boxed{2800=a}$
