Answer:

0.4 cm

Step-by-step explanation:

The magnifying glass basically zooms into smaller objects. If the insect appears to be 2cm, then it is actually smaller than this. It cannot be 10 cm.

If the scale factor is 5, then this means that the insect is zoomed in 5 times through the magnifying glass. Use the following ratio:

$\frac{2}{5}$

This fraction can also be seen as division, so:

$2$ ÷ $5=0.4$

The insect is actually 0.4 cm long.

(or 4 millimeters)

Answer:

$f(t)=50+10(t-70)$

Step-by-step explanation:

Let the outside temperature be $t$ degree.

So, when $t=70$ degree, number of members, $f(t)=50$

Now, for every degree rise in temperature, 10 members gets added.

So, when the temperature is $t$ degrees, rise in temperature is $(t-70)$ degrees.

Therefore,

For $(t-70)$ degrees rise, number of members added = $10(t-70)$

Hence, total number of members added as a function of temperature is given as the sum of members at $t= 70$ degrees and for $(t-70)$ degrees rise. This gives,
