Answer:
2 1/4
Step-by-step explanation:
Number 1 is incorrect because 1/4 x 9 is 2 1/4 not 1 1/4.
To multiply fractions, multiply directly across. So multiply 1/4 x 9/1 to get 9/4 which converted into a mixed number is 2 1/4.
For question 11, you essentially need to find when h(t) = 0, since that is when the height of the ball reaches 0 (ie touches the ground).
For question 12, it is asking for a maximum height, so you need to find when dh/dt = 0 and taking the second derivative to prove that there is maximum at t. That will find you the time at which the ball will hit a maximum height.
Rinse and repeat question 12 for question 13
Answer:
4/3 per minute.
Step-by-step explanation:
Multiply both 1/4 and 1/3 to get 1 minute. 1/3x4=4/3
In the problem, two legs measurement were given such as:
Leg 1 = 12 inches
Leg 2 = 15 inches
We need to solve for the third leg. Since it is a right triangle, we can use Pythagorean theorem in solving the missing leg:
c²=b²+a²
When we assume that the third leg is the "c", we can for the value such as:
c² = 12²+15²
c=19.21
When we assume that the third is either "a" or "b":
15² =a² + 12²
a=9
Then, the possible measurement of the third leg is 9 or 19.21.
The difference between the two possible answer is shown below:
Difference = 19.21 -9 = 10.21
Difference =10.21
