Answer=5/16 or 0.3125 feet
Step-by-step explanation:
The line going from side to side is the x coordinate and the first number in the ordered pair the second number is the y coordinate which is the line going up and down. You take the first number and go to it on the line going side by side then you stay there and go up or down from that position how many spaces the second number is.
D=√(x2-x1)² + (y2-y1)²
so what you do is take the two coordinates and you plug them in so lets say you have (2,3) and (5,7)
so you will take the first coordinate and plug it in where the X1 and Y1 is and the second coordinates where the X2 and X1 is just like so:
ex: D=√(5-2)² + (7-3)²
subtract those numbers
D=√(3)² + (4)²
square what you have left:
D=√9+16
add them together
D=√25
Square root it ((this can be done with a calculator)) then you will have your answer
D= 5
And thats all you have to do!
Answer:
[-3, 1, 9, 11]
Step-by-step explanation:
Plug in each number of the domain for x to get the range:
2(0)-3= 0-3 = -3
2(2)-3= 4-3= 1
2(6)-3= 12-3= 9
2(7)-3= 14-3= 11
