Answer:
t = 1 1/7 ≈ 1.1429 seconds
Step-by-step explanation:
Filling in the given height, we can solve for t:
640 = -490t^2 +1120t
49t^2 -112t +64 = 0 . . . . . divide by 10, put in standard form
(7t -8)^2 = 0
t = 8/7 . . . . . . . the value of t that makes the factor(s) zero
The model rocket will reach its maximum height of 640 cm after 1 1/7 seconds.
Answer:
a. (53, 12)
b. I couldn't find this without making a graph myself, hopefully someone will find it or you can figure it out for yourself using the answer I did provide.
I believe the answer you're looking for is A. Commodity money
Hope this helps!
Think of two points on a straight line. The first point is (0,8) representing 8 employees at time 0. The second point is (6,26), representing 26 employees after six months have gone by.
26-8
The slope of this line is m = ---------- = 18/6 = 3
6-0
This indicates that 3 new employees are taken on on average each month.
This situation can be represented as
E(x) = 8 + 3x, where x is the number of months that have passed, and E(x)
represents the number of employees at that point in time.
Answer:
300ft²
Step-by-step explanation:
base=LW = 10x10=100
triangles=1/2bh = 1/2(10)(10)=50 (4 of them)
100+4(50)=
100+200=300ft²
