Part a - obtaining conversion factors from unit equality relationships in an experiment you are performing, your lab partner has
DanielleElmas [232]

Solution:

As we given that 1 inch=2.54 cm

then using this conversion factor we can write  28.4 inch=28.4* (1 inch)

and further it can be written as

28.4* (1 inch)*(2.54 cm/1 inch)=28.4*2.54 cm= 72.136 cm

Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.

What is 3log2 x-(log2 3-log2(x+4)) written as a single logarithm?
zloy xaker [14]
Answer:
log₂(\frac{x^2(x+4)}{3})

Explanation:
Before we begin, remember the following:
logₐ(x) - logₐ(y) = logₐ(\frac{x}{y})
alog(x) = log(xᵃ)

Now, for the given we have:
3 log₂(x) - (log₂3 - log₂(x+4))
log₂(x²) - log₂(\frac{3}{x+4})

log₂(\frac{x^2}{ \frac{3}{x+4} }) = log₂(\frac{x^2(x+4)}{3})

Hope this helps :)

A city grid of Anytown, USA is shown on the grid below. The fire department is represented by quadrilateral RSTU. Another fire d
Alekssandra [29.7K]
Answer: option d. C (0,3), D (0,5).

Justification:

1) The x - coordinates of the vertices A and B are shown in the diagrama, They are both - 4, so the new vertices C and D must be in a line parallel to y = - 4.

2) The y-coordinates of the  vertices A and B are also shown in the diagrama. They  are equal to 3 and 5 respectively.

3) We can see that the new points C and D must be over a parallel line to y = - 4 and that their distance to the points A and B has to be the same distance of the point R and S to U and T.

That distance is 4, so the line may be y = - 7 or y = 0.

4) If the line is y = 7 the points C and D would have coordinates (-7,3) and (-7,5), but this points are not among the options.

5) If the line is y = 0 the points C and D would have coordinates (0, 3) and (0,5), which is precisely the points of the option d. That is the answer.

bagirrra123 [75]

Answer:

In this item, we are given that out of 12 ounces of ingredients comprising the milkshake, there are 4 ounces vanilla. Expressing this into fraction will give us an answer of 4/12. This fraction can be one of the answers. Since we are asked for two fractions, we can simplify 4/12 such that we get an equivalent fraction that is equal to 2/6. Hence, the answers to this question are 4/12 and 2/6.
