Answer:
The diver will take 2.449 seconds to enter the water.
Step-by-step explanation:
We have been given that quadratic equation for the diver jumps is

We have to find the time taken for the diver to enter the water. When the diver enters the water, the height becomes zero.

Therefore, the diver will take 2.449 seconds to enter the water.
Answer:
Microscopes cost $44 and Dissection Kits cost $11
Step-by-step explanation:
Using the information given, we can make the system of equations:
30x+48y=1848
x represents the price of microscopes and y represents the price of dissection kits.
We also know that microscopes will be 4x the price of dissection kits. Therefor:
x=4y
We can plug these two equations together to find the answer.
30(4y)+48y=1848
120y+48y=1848
168y=1848
y=11
Using the y-value, can find the x-value.
x=4(11)
x=44
Just divide 18 by 20 , so its 0.9
