Answer:

Step-by-step explanation:

The basic model for this growth is the exponential function:  y = a(b)^c, where a is the initial value, b is the growth rate and c is the time.

Here we have P = fish population = (2 fish)(3)^t

The scale model of a skyscraper being built is 4.2 feet tall. When it is finished, the skyscraper will be 525 meters tall. What
luda_lava [24]
There are two scales that may be possible for this scale model; one where it's for every foot and one where it's for every meter.
The for every foot would be better to find out since the scale would be easier to use.
First, you have to divide each sided by 4.2, since you want to find how many meters for each foot.
4.2 \div 4.2 = 1 \\ 525 \div 4.2 = 125
For every 1 foot used in the model, the actual will be 125 meters.
1 ft = 125 m

Predict if the product will be greater than, less than or equal to the second factor 4/5 x 1 2/5 = y
Radda [10]

Answer:

The product will be less than the second factor.

Step-by-step explanation:

Given the expression

\frac{4}{5}\:\times \:1\frac{2}{5}\:=y

solving to determine the product value

y=\:\frac{4}{5}\times \:\:1\frac{2}{5}

  =\frac{4}{5}\times \frac{7}{5}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}

  =\frac{4\times \:7}{5\times \:5}

  =\frac{28}{5\times \:5}

  =\frac{28}{25}

As the value of the second factor is:

1\frac{2}{5}=\frac{7}{5}=1.4

And the product value is:

y=\frac{28}{25}=1.12

It is clear that the product value 'y = 1.12' is lesser than the second factor value '1.4'.

i.e. 1.12 < 1.4

Thus, the product will be less than the second factor.
