Step-by-step explanation:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis.
Answer:
7×10^(-2)×8×10^5 = 56000
convert to scientific notation = 5.6 × 10^4
(scientific notation)
= 5.6e4
(scientific e notation)
= 56 × 10^3
(engineering notation)
(thousand; prefix kilo- (k))
= 56000
(real number)
Step-by-step explanation:
Use the pythagorean theorem to solve this: a^2 + b^2 = c^2.
You already have a and b which are 3 and 4. Square them up and you will get 9 + 16 = c^2.
Add.
25 = c^2
Lastly, square root both sides.
5 = c
The length of AB is 5.
The answer is $9,100
6,500 x .08 = 520
520 x 5 = 2,600
2,600 + 6,500 = 9,100
Hope this helps!
