Answer:
irrational
Step-by-step explanation:
irrational because there will still be a 2 under the root when you simplify to 2√2
Answer: I really can't answer this without more info
Step-by-step explanation: needs more info to solve
Answer:
Step-by-step explanation:
Use the distance formula.
Subtract the x-coordinates and square the difference.
3 - 7 = -4; (-4)^2 = 16
Subtract the y-coordinates and square the difference.
4 - 2 = 2; 2^2 = 4
Add the differences and take the square root of the sum.
16 + 4 = 20; sqrt(20) = sqrt(4 * 5) = 2sqrt(5)
distance = 2sqrt(5)
You can use the distance formula which does the same thing.
First we have to work out the area of the trapezoid using the formula;
1/2 (a+b) h
The height is 16ft, and a = 24ft, and b = 15ft
Put this into the formula
1/2 (24 + 15) 16
1/2 39 * 16
39 * 8 (you can halve the 16)
= 312 ft squared
Now we simply multiply the area by the cost per square foot to get our answer.
312 * 0.79 = $246.48
