2/5 + 4/9 +15 = 18+20+675/45
= 713/45
Answer: Sam made 713/45 or 15.84 bread rolls all in all.
Answer:
see below
Step-by-step explanation:
h=−4.9t^2 +39.2t
When will if fall back to the ground
When will h=0
0 =−4.9t^2 +39.2t
Factor out a -t
0 = -t (4.9t -39.2)
Using the zero product property
-t =0 4.9t - 39.2 =0
t =0 4.9t = 39.2
t =39.2 /4.9
t =8
It will reach the ground again at 8 seconds
The maximum height is halfway between the zeros
(0+8)/2 = 4
It will reach the max height at 4 seconds, substituting this in to find the max height
h=−4.9 (4)^2 +39.2(4)
h = 78.4 meters
This will only be applicable between t=0 and t=8 seconds
0≤t≤8 seconds
Answer:
Step-by-step explanation:
we know that
In a rectangle the two diagonals are congruent (same length), and each diagonal bisects the other.
so
In this problem
solve for x
Hello there ^ _ ^
-2w + 5 < -5
-2w < -5 - 5
-2w < -10
Divide both sides by -2
-2w/-2 < -10/-2
w > 5
I hope this help!
A+ Guaranteed!
Answer:
The coordinates of H’ is (-1,-6)
Step-by-step explanation:
Here, we want go get clockwise rotation about the origin
mathematically, if we had this kind of rotation, it would be that
(x,y) will turn to (y,-x)
So we have it that (6,-1 becomes)
(-1,-6)
