Y=-16t^2+400, The camera will hit the water when y=0 so:
16t^2=400
t^2=25
t=√25, and since t≥0
t=5 seconds
Answer:
The length and width of the scale drawing of 1 cm to 5 m are;
Length of scale drawing = 10 cm
Width of scale drawing = 5 cm
Step-by-step explanation:
The given information are;
The length of the actual swimming pool = 50 meters (or 5 m)
The width of the actual swimming pool = 25 meters (or 20 m)
The scale of the drawing to represent the swimming pool is 1 centimetres (or 1) cm = 5 meters (or 5 m)
Therefore;
The 50 meters actual length = 50 m/(5 m) × 1 cm =10 × 1 cm = 10 cm
The 25 meters actual width = 25 m/(5 m) × 1 cm =5 × 1 cm = 5 cm
The length and width of the scale drawing of 1 cm to 5 m are 10 cm and 5 cm respectively.

Answer:
Hence, the correct option is 82%.
Step-by-step explanation:
Consider the provided information.
In your university nursing program the ratio of students who scored a grade of A vs B vs C on the final exam is 12:29:9.
We need to find the percentage of student who scored a grade of "B" or higher.
Let x is the common factor for the proportion.
Then, the number of students who got grade A is 12x
The number of students who got grade B is 29x
The number of students who got grade C is 9x.
Thus the total number of students = 12x+29x+9x = 50x
The percentage of student who scored a grade of "B" or higher:
12x+29x = 41x

Hence, the correct option is 82%.
