Answer:
m= <u>y2 - y1</u>
x2 - x1
m= <u>-7 + 3</u> ( I have + 3 and 4 because when negative cancel negative, it is
-2 + 4 positive)
= <u>-4</u> = 2
-2
Step-by-step explanation:
- write down the formula for finding slope.
- replace the y's and x's with the values.
- add everything together
- divide
Segment CD
This is because where there is a perpendicular line, there has to be a right angle(90degrees) at the point of contact.
Answer: 6(x)-2/8
Step-by-step explanation:
6 parentheses to represent multiplying,and unknown number inside you would use a variable, and then subtract 2 and use the slash sign ( / ) to represent the fraction bar and write 8 next to it
.
Let x = length of the park
Let y = width of the park
Because the area is 392392 ft², therefore
xy = 392392 (1)
Because three sides of fencing measure 5656 ft, therefore
2x + y = 5656 (2)
That is
y = 5656 - 2x (3)
Substitute (3) into (1).
x(5656 - 2x) = 392392
5656x - 2x² = 392392
2x² -5656x + 392392 = 0
x² - 2828x + 196196 = 0
Solve with the quadratic formula.
x = (1/2)*[2828 +/- √(2828² - 4*196196)]
= 2756.83 or 71.17
Answer:
The possible dimensions are 2756.8 ft and 71.2 ft (nearest tenth)
