That is sort of a vague question, but in general you can:
1. Analyze the problem to identify:
a) What type of problem it is (word problem, algebra,etc.)
b) What the question is asking you (you must understand the question to do it)
2. Draw visuals (ex. venn diagram), graphs and tables to help you start the question
3. Create a plan to solve the question. For example the formulas and materials you need.
4. Try to solve the problem. This can be achieved in many ways.
5. If you are having problems, refer to the internet or ask a friend, teacher, parent or tutor.
Answer: 60.9 u^2
Step-by-step explanation:
The area of a trapezoid can be calculated as seen in the attachment.
Thus:
![A = \frac{3.7+14.2}{2} * 6.8\\A = \frac{17.9}{2} *6.8\\A = 8.95*6.8\\A = 60.86\\Round\\\left[\begin{array}{c}A=60.9\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B3.7%2B14.2%7D%7B2%7D%20%2A%206.8%5C%5CA%20%3D%20%5Cfrac%7B17.9%7D%7B2%7D%20%2A6.8%5C%5CA%20%3D%208.95%2A6.8%5C%5CA%20%3D%2060.86%5C%5CRound%5C%5C%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7DA%3D60.9%5Cend%7Barray%7D%5Cright%5D)

Answer:
max height = 7.5 ft
1.3 ft far
Please check below for the detailed answer
Step-by-step explanation:
<u>Given: </u>
f(x) = −0.3x^2 + 2.1x + 7
a) To obtain the maximum height , find f'(x)
f'(x) = - 0.6x + 0.8 = 0
=> x = 0.8 / 0.6 = 1.33 feet
So f(x) is maximum at a horizontal distance of 1.33 ft
To find the max height , find f(1.33)
f(x) = −0.3x^2 + 2.1x + 7, plug in 1.33 for x
=> f(1.33) = −0.3(1.77) + 0.8(1.33) + 7 = 7.5 ft
So the answer is
Maximum height = 7.5 ft , and 1.3 ft far from where it was thrown.
