Answer:

Step-by-step explanation:

To calculate the weighted moving average for period 13 with weights 0.4 and 0.3.

P13 = (30.7x 0.4) + (42.0x 0.3)

P13 = 12.28 + 12.60

P13 = 24.88

Which of the following shows the extraneous solution to the logarithmic equation below???

avanturin [10]

Short Answer x = - 6
Remark
You gave the second best answer.

The trick here is not to divide both sides by 2. Solve the problem this way.

log_5(x + 1)^2 = 2 Take the antilog of both sides
(x + 1)^2 = 5^2 Expand the equation
x^2 + 2x + 1 = 25 Subtract 25 from both sides.
x^2 + 2x - 24 = 0 Factor
(x + 6)(x - 4) = 0 Find the zeros.

x + 6 = 0
x = - 6 <<<<<<<< Answer. This is the extraneous root.
The reason this is an extraneous root is that x<=0 do not have a logarithem

x - 4 = 0
x = 4 This is a legitimate result to the original equation.

A duck is 2 feet below the surface of a pond. If its position can be recorded as −2 feet, what would the position of 0 represent

Y_Kistochka [10]

0. Zero is zero. Moving a point 2 ft below deducts 2 from the original number(whatever it was). Moving a point 0 ft below deducts nothing so the answer is 0.

Eli, Freda and Geoff were given £800 to share in the ratio of their ages.

algol13

First, we are going to find the sum of their age. To do that we are going to add the age of Eli, the age Freda, and the age of <span>Geoff:
</span> $9+13+18=40$
The combined age of Eli, Freda, and Geoff is 40, so the denominator of each ratio will be 40.

Next, we are going to multiply the ratio between the age of the person and their combined age by <span>£800:
For Eli: </span> $\frac{9}{40} *800=180$
For Freda: $\frac{13}{40} *800=260$
For Geoff: $\frac{18}{40} *800=360$
<span>
We can conclude that Eli will get </span>£180, Freda will get £260, and Geoff will get <span>£360.</span>
