Answer:
9.2 seconds.
Step-by-step explanation:
We have been given an equation that represents dive of a bird as 
, where x represents the time the dive lasted in seconds and y represents the height of the bird in meters.
We can see that our given equation is a parabola. The leading coefficient is positive, so our parabola will be an upward opening parabola.
Upon graphing our given equation, we will get our required graph as shown in the attachment.
As x represents the time the dive lasted in seconds and y represents the height of the bird in meters, so the bird will be at the surface when the graph will cross x-axis.
We can see that graph crosses x-axis at 
.
Upon rounding to nearest tenth, we will get:
.
At 
the bird dives in water and goes down the water surface and at 
the bird comes to the surface, therefore, the bird will be at surface after 9.2 seconds.

Hello!
130 ounces is about 4 quarts so 5 quarts is larger
130 ounces is slightly above 16 cups so 16 cups is lower
130 ounces is about 8 pints so 9 pints is larger
130 ounces is slightly above a gallon so 2 gallons is larger
130 ounces is slightly above a gallon so 1 gallon is smaller
The answers are A) 5 quarts, C) 9 pints, and D) 2 gallons
Hope this helps!
Answer:
because there's an equals sign and if you want the answer x=1
Step-by-step explanation:
because 9=3x+6 cancel out 6, 3=3x divided on both sides, 1=x
