Answer:
A. 4.5 ft
B. 4 ft
C. 1 ft
Step-by-step explanation:
If you pretend that h is replacing y and d is replacing x and you would graph the equation, then you would get a parabola that opens down.
You would need to find the vertex of the parabola. The ordered pairs would be (d, h) instead of the normal (x, y).
A. The maximum height will be the h value of the vertex
B. Let h = 0 and solve the equation for d. That will give you distance from the stump that the frog landed.
C. The distance from the log at the maximum height is the d value of the vertex
So, that is what is needed to be done.
Without me going thru all the work, the vertex is (1, 4.5) and the solutions to the equation when h = 0 are 4, -2 (discard -2 since a distance cannot be negative)
So the answer to A is 4.5 ft.
The answer to B is 4ft.
The answer to C is 1 ft.
Now, can you find the vertex on your own and can you solve the equation when h = 0? I hope so. OK?
Answer:
To find the answer, you must multiply/divide the amount in cups by calories per cup.
Step-by-step explanation:
Butter only has 0.3 cups, so The calories will only be 30% of what is written down. 30% of 1627= <u>488.1 calories</u>
Marshmallows is 4.25 times larger then the calories per cup, so now you'll have to multiply.
4.25*159=<u>675.75 calories</u>
Finally, Cereal is 5.5 times larger then the calories per cup, so we will multiply again.
5.5*101=<u>555.5 calories</u>
<u />
Finally, add all the number together to find the total amount of calories in the marshmallow treats.
555.5+675.75+488.1=<u>1,719.35 calories</u>
There is a total of 1,719.35 calories in the marshmallow treats.
Answer:
0.67449
Step-by-step explanation:
Let be the 3rd quartile of normal distribution .
-z-score corresponding to the upper quartile can be calculated in excel as:
- In Excel, click on any empty cell'
- Type the function NORMINV
- Enter the probability as 0.75, mean= 0 and standard deviation=1
- Click the enter button.
-The output is 0.67449. Hence, the z-score corresponding to the upper quartile (Q3) of a normal distribution is 0.67499
