Answer:
√20 or 4.47 ish
Step-by-step explanation:
√(1--3)²+(-2--4)²
√(1+3)²+(-2+4)²
√(4)²+(2)²
√16+4
√20
4.47 ish
(Hopefully this is correct, have a nice day!)
1: 5 2: 9 or 10
For question 1 we can round 115 to 100, 5x100 is 500 which is closer to 545 than 7x100 = 700.
Answer:
See below.
Step-by-step explanation:
It transforms to the Pythagoras theorem.
c^2 = a^2 + b^2 - 2ab cos C
If C = 90, cos C = zero so the last term disappears.
c^2 = a^2 + b^2 - 2ab * 0
c^2 = a^2 + b^2.
Answer:
The dimensions are 6 by 6
Step-by-step explanation:
Calculus answer:
2x +2y= 24
xy= A
2x=24-2y
x=12-y
(12-y)(y)= 12y- y^2
the Derivative is = 12-2y
Then set that equal to zero 0=12-2y
-12=-2y
y=6
Confirm that 6 is a maximum by using a wiggle graph
wiggle graph -∞<---inc--6---dec-->∞
6 is a maximum
plug into original equation
2x + 2(6)=24
2x+12=24
2x=12
x=6
----------------------------------------------------------------------------------------------------
y=6
x=6
