We are given with the table of x  and y values

We use the given y values to find the required equation

When the first difference between the y values are same then it is linear.

When the common ratio between y values are same then it is exponential.

When the second difference of y values are same then it is quadratic.

Lets find the difference between y values

\frac{1}{4} - \frac{1}{8} = \frac{1}{8}

\frac{1}{2} - \frac{1}{4} = \frac{1}{4}

1 - \frac{1}{2} = \frac{1}{2}

The difference is not same . so we cannot choose y= mx+b

Now we find the common difference between y values

\frac{\frac{1}{4}}{\frac{1}{8}} = 2

\frac{\frac{1}{2}}{\frac{1}{4}} = 2

\frac{1}{\frac{1}{2}} = 2

The common ratio is 2. So its exponential.

The required equation y=ab^x

liq [111]

Answer:

The cost of one bear is <u>$47,000</u>.

Step-by-step explanation:

The question is incomplete and the data is missing so the complete question with data is below with attached files:

To celebrate there 125 anniversary, a company in Germany produced 125 very expensive teddy bears. The bears,known as the "125 karat teddy bears", are made mohair,silk and gold thread and have diamond and sapphire eyes.

The chart shows the approximate cost of " 125 teddy bears". Based on the pattern, how much does one bear cost?

Now, to get the cost of one bear.

So, we solve it by using unitary method:

If 4 bears cost = $188,000.

Then 1 bear cost = 188000\div 4=47000

Thus, cost of one bear is $47,000.

Now, we check it by using another pattern of the data:

If 7 bears cost = $329,000.

Then 1 bear cost = 329000\div 7=47000.

Hence, the cost of one bear is $47,000.

Therefore, the cost of one bear is $47,000.

The number of seats in a row has been increased at a rectangular-shape movie theater after renovation so that it is now five mor
Damm [24]

Let the number of rows be = r

Let the number of seats per row be = s

we know that the number of seats is 126.

So, s\times r=126    ..... (1)

As given, there are five more seats per row than the number of rows, so we can say that:

s=r+5

Putting this in equation (1)

(r+5)*r=126

r^{2}+5r=126

r^{2}+5r-126=0

r^{2}+14r-9r-126=0

(r+14)(r-9)=0

r=-14 and r=9 (neglecting the negative value) we get r=9

And s=r+5

so, s =9+5=14

Hence, there are 5 rows and 14 seats per row.
