Answer:
sqrt(x^2+y^2)
Step-by-step explanation:
x^2+y^2=z^2 (Pythagorean theorem)
sqrt(x^2+y^2)=sqrt(z^2)
sqrt(x^2+y^2)=z

Answer:
5/2=2.5, while 1/3= aprox 0.333, therefore 5/2 is not equal to 1/3.
Step-by-step explanation:
Here is the long division table for 5/2
2. 5 0 0
2 5. 0 0 0
− 4
1 0
− 1 0
0 0
− 0
0 0
− 0
0
Here is the long division table 1/3 ( to three decimal places)
0. 3 3 3
3 1. 0 0 0
− 0
1 0
− 9
1 0
− 9
1 0
− 9
1
An easier way to do 5/2 is to think of 50/2, which is 25, and then add a decimal point, making it 2.5.
An easier way to do 1/3 is to think of it as one third (of one), or 0.333 repeating.
Answer:
Would 50 divided by 40 work?
Step-by-step explanation:
(27⁽⁻ˣ⁺³⁾) (9⁽ˣ⁺¹⁾) = 81
Instead of using logarithmic to find x, Notice that 27, 9 and 81 are the perfect powers of 3. Since 27 = 3³, 9 = 3², and 81 = 3⁴, so
(3³⁽⁻ˣ⁺³⁾) (3²⁽ˣ⁺¹⁾) = 3⁴
3³⁽⁻ˣ⁺³⁾⁺²⁽ˣ⁺¹⁾ = 3⁴
If the bases are the same, then cancel it and bring the power as a new base.
3(-x+3) + 2(x+1) = 4
-3x + 9 + 2x + 2 = 4
-x + 11 = 4
-x = 4 - 11
-x = -7
x = 7
