We are given with:
Average height of plants to be at least 73 inches
Three plants with heights of
70, 71, 72
The inequality that can be used to determine the possible heights of the fourth plant is:
(70 + 71 + 72 + x) / 4 ≥ 73
Solving for x
x ≥ 79
Answer:
233
Step-by-step explanation:
Given the equation, V = XLJ:
In order to solve for X, divide both sides of the equation by LJ:
V / (LJ) = (XLJ) / LJ
Doing so gives you the final answer:
V / LJ = X
In order to divide, you need to find the reciprocal of 4/15 and multiply it by 2/3. So, 2/3*15/4
The answer is 5/2
First we need to find delta for function ax2+bx+c = 0
DELTA = b2-4ac
DELTA = 25 -( 4*1*5)= 25 - 20 = 5
x1 = (-b-√DELTA)/2a = (-5 - √5)/2
x2 = (-b+√DELTA)/2a (-5+√5)/2
x1 and x2 are zeros of this function
