She is correct because a negative subtracted by a negative is positive.
Answer:
9.2
Step-by-step explanation:
You want the distance between A(2, 0) and B(0, 9).
<h3>Distance</h3>
The distance formula is based on the Pythagorean theorem. It tells you the distance between (x1, y1) and (x2, y2) is ...
d = √((x2 -x1)² +(y2 -y1)²)
For the given points, this becomes ...
d = √((0 -2)² +(9 -0)²) = √(4+81) = √85
d ≈ 9.2
The distance between A and B is about 9.2 units.
20 x 18 x 5= 1,800
20 times 18 equals 360, then you mutiply 5 and get 1,800
Answer:
11%
Step-by-step explanation:
1/3 (twix)
1/3 (snicker)
1/3 x 1/3 = 1/9
1/9 = .11
.11 = 11%
Answer: =34
=3⋅3⋅3⋅3
=81
For example, 3 to the power of -4:
=3−4
=134
=13⋅3⋅3⋅3
=181
=0.012346
Step-by-step explanation: the solution is expanded when the base x and exponent n are small enough to fit on the screen. Generally, this feature is available when base x is a positive or negative single digit integer raised to the power of a positive or negative single digit integer. Also, when base x is a positive or negative two digit integer raised to the power of a positive or
negative single digit integer less than 7 and greater than -7.
hopefully this is right :/
