3 (inches) / 6 (hrs) = 1/2 (or 0.5) inches per hr <==
Answer:
128.605m^2
Step-by-step explanation:
because the kite has equal sides you can simply just do 8.5m x 10.2m+8.5m x 4.93m :D
The rate of change of Pete's height from 3 to 5 years can be determined as,
Thus, the required rate of change from 3 to 5 years is 4 in/year.
You can do this 2 ways, one is knowing the special right triangles called triplets. An example of a triplet would be 3-4-5 where the largest value is the hypotenuse. In this example, the other 2 sides are 3 and 4 and the missing side is the hypotenuse, so using the knowledge of triplets, we can find that the hypotenuse is 5.
algebraically, we can use the Pythagorean theorem; a^2+b^2=c^2 where a and b are the opposite and adjacent and where c is the hypotenuse. We can then substitute in the values to get : 3^2 + 4^2 = c^2. When simplified, we get 9+16=c^2. Simplify further, and get 25=c^2. Now we Square root both sides to solve for C. Finally, we get C=5. Your missing side is 5.

26.) C
27.) B
