Three ordered pairs would be
x y
0, -15
1, -12
2, -9
ect...
By the Pythagorean theorem,
.. x^2 +(x -46)^2 = (x +4)^2
.. 2x^2 -92x +2116 = x^2 +8x +16
.. x^2 -100x +2100 = 0
.. (x -50)^2 -400 = 0
.. x = 50 ±20 . . . . . only x=70 makes any sense in the problem
The height, x, of the tree is 70 meters.
48 stamps because 29-5=24 , 24x2=48
Answer:
f(2b) = 4b^2 +4b +1
Step-by-step explanation:
Put 2b where x is and simplify.
f(2b) = (2b)^2 +2(2b) +1
f(2b) = 4b^2 +4b + 1
63 students. To solve, you first ned to determine the total cost for each student by adding 300 and 5, which equals $305. You then need to see how many times $305 will go into $19215, which shows how many students went. $19215 divided by $305 equals 65.
