e-lub [12.9K]

Using proportions, it is found that Donald should order 4 of the 0.05 gram tablets.

  • This question is solved by proportions, using a <em>rule of three</em>.
  • 4 tablets are needed, and they should combine for 0.2 grams. How many grams is there going to be on one tablet?

The <em>rule of three</em> is:

1 tablet - x grams

4 tablets - 0.2 grams

Applying cross multiplication:

4x = 0.2

x = \frac{0.2}{4}

x = 0.05

How to do number 13 and 14
Murrr4er [49]

From the information: v is 64 while c is 5

Differentiate the new equation h=-16t^{2} + 64t + 5 to get \frac{dh}{dt}= -32t + 64.

no 13). At maximum height this derivative equals zero so: -32t + 64 = 0;  -32t = -64; t=2.Hence ans is 2 secs

no 14). put t as 2 sec in the equation: h=-16t^{2} + 64t + 5.  This gives

h=-16( 2^{2}) + 64(2) + 5; h=-64+128+5=69. Hence h is 69ft
