Answer:
1.8
Step-by-step explanation:
So, we can say that the square root of 3.24 is 1.8 with an error smaller than 0.001 (in fact the error is 0.0000276241). this means that the first 4 decimal places are correct. Just to compare, the returned value by using the javascript function 'Math. sqrt(3.24)' is 1.8
Answer:
Solution: an Experimenter whats to estimate the average water consumption per family in the city
if individual families are used as the sampling united, a frame could be using censes data or atelephone book
if dwelling are used as the sampli units, aframe could be using Address book or city directory
If city blocks are used as the sampling units, aframe could been using is city directory
Step-by-step explanation:
Answer:
a.)Q' = -kQ + r
b.)Q =
c.) Limiting long run value of Q =
Step-by-step explanation:
a.)
The rate of change is directly proportional to the quantity, Q
⇒ ∝ Q
⇒ = -kQ ( because it is decreasing )
Also given, quantity is increasing with a constant rate r
⇒ = -kQ + r
⇒Q' = -kQ + r
b.)
As we have
= -kQ + r
⇒ = dt
⇒∫ = ∫dt
⇒-
⇒log(-kQ + r) = -kt -kC
Taking exponential both side, we get
⇒-kQ + r =
⇒-kQ = -r +
⇒Q = -
⇒Q = -
⇒Q = - .......(1)
Now,
At t = 0, Q = 0
0 = - B
⇒
⇒B = r
∴ equation (1) becomes
Q = -
⇒Q =
c.)
for limiting long run value of Q
=
=
⇒Limiting long run value of Q =
Answer:
(1) The slope intercept should be y=1/2x-5
So the table should be
x y point
-2 -6 (-2,-6)
0 -5 (0,-5)
2 -4 (2,-4)
(2) The slope -5/4
Step-by-step explanation:
(1) The reason why when she graphed the points is incorrect is because she needs to graph it in point slope form not in standard form and when she used the equation.
To find the slope intercept form you need to get the y on one side by itself:
x-2y=10
Subtract x on both sides:
-2y=-x+10
Divide by -2 on both sides:
y=1/2x-5
(2)The formula for the slope is y2-y1/x2-x1
-2-3/5-1
Which is -5/4
Thus the slope is -5/4
Hope this helps!
