What exclusions are placed on the variable a for the fraction (am^2+4m)/a^2+4

Mathematics

RUDIKE [14]3 years ago
7 0

Answer:

None.

Step-by-step explanation:

The only possible restriction in the rational expression \frac{am^2+4m}{a^2+4} can originate in its denominator being zero for some values of a. However, since the denominator in this case (a^2+4) is always positive (and larger or equal to 4) for all values, no restrictions on the variable a exist.

A florist makes 215 bouquets in 5 days. How many does she make per day
Liono4ka [1.6K]

With questions like these, I like to use a system of operations my teacher told me.

First, we have to identify what the question is asking us to find. The question is asking us to find how many bouquets a florist makes per day (which is in one day).

Then, we have to find information that will help us answer the question. She makes 215 bouquets is 5 days.

Now, you put it together!

If she makes 215 bouquets in 5 days, and we need to find out how many she makes in 1 day, we need to divide 215 by 5!

215 / 5 = 43.

The florist makes 43 bouquets per day!

The computation of the figure illustrates that 0.47 expressed as a fraction in simplest form is 43/90.

<h3>How to compute the fraction?</h3>

From the information given, let a = 0.47. Now 10a = 4.777 .... equation i

100a = 47.77 ..... equation ii

Subtract equation i from ii

100a - 10a = 47 - 4

90a = 43

Divide both side by 90

90a/90 = 43/90

a = 43/90

The relationship between women's whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length
Oksana_A [137]

Answer:

an=7.35+ 0.33(n-1)

Step-by-step explanation:

The relationship between women's whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length in inches that corresponds to a shoe size of  n.

We are given values for n=7 and n=12 as a7=9.33 and a12=11

So, we proceed from the options and check which an satisfies these values:

an = 7.35 + 0.33(n-1)

when n = 7:

an = 7.35 + 0.33 (7-1)

an = 9.33

when n = 12:

an = 7.35 + 0.33 (12-1)

an = 10.98≈11

Hence, correct option is:

an=7.35+ 0.33(n-1)
