Answer:
x = ±sqrt(5/2)
Step-by-step explanation:
6x^2−2=13
Add 2 to each side
6x^2−2+2=13+2
6x^2 = 15
Divide each side by 6
6/6x^2 = 15/6
x^2 = 5/2
Take the square root of each side
sqrt(x^2) = ±sqrt(5/2)
x = ±sqrt(5/2)
Suppose we want to find root (s)
To solve the problem using this method, you must apply the following equation:
xn + 1 = (1/2) * (xn + (S / xn))
Then, comparing with the expression shown in the image, we have to:
xn = 11.5
answer
the missing information in the problem to find √130 by using the Babylonian method is
A. 11.5
25,672 if you take it step by step you will get it
Working Formula:
V = s^3
Given:
dV/dt = -4 cubic meters per minute
V = 125 cubic meters
Required: ds/dt (rate of change of edge per minute) at V = 125 m^3
Solution:
Differentiate, equation below
V = s^3
dV/dt = 3*s^2 (ds/dt)
-4 = 3*s^2 (ds/dt)
ds/dt = -1.33/s^2 -----------> eq. (1)
V = s^3
(125)^0.33 = (s^3)^0.33
s = 5 ------------> eq. (2)
Substitute eq. (2) to eq. (1), we get
ds/dt = -1.33/(5)^2 = -0.053 meters per minute
<em>ANSWER: -0.053 meters per minute</em>
This is easy because they y's will cancel out. I love this method it's the easiest one out of substitution, and graphing.
So the Y's will cancel out an you will get x=2. Then you plug the 2 in for x in the first equation. so it will 2+y-3. You subtract 2 from both sides to get y=1.
So the ordered pair is(2,1) :)
