Answer:
37.6
Step-by-step explanation:
x² = a² + b² - 2ab cos 140°
x² = 20² + 20² - 2(20)(20)(-0.766)
x² = 400 + 400 - 800(-0,766)
x² = 800 - (-612.835)
x² = 800 + 612.835
x² = 1412.835
x =√1412.835 = 37.6
The coordinates of the image point are given to be B(4, -8). We are to find the coordinates of pre-image that is the coordinates before the translation.
The translation made was (x-2, y+3)
This means, the x coordinate was moved 2 units to left and y coordinate was moved 3 units above.
So, the coordinates of original point will be, 2 units to right of B and 3 units down of B.
So the coordinates will be (6, -11)
Answer:
6/6
Step-by-step explanation:
If a standard number cube has six sides and all the numbers are larger than 0 you have a 6/6 chance
Answer:
Step-by-step explanation:
34=-11+7A
We move all terms to the left:
34-(-11+7A)=0
We add all the numbers together, and all the variables
-(7A-11)+34=0
We get rid of parentheses
-7A+11+34=0
We add all the numbers together, and all the variables
-7A+45=0
We move all terms containing A to the left, all other terms to the right
-7A=-45
A=-45/-7
A=6+3/7
