Answer:
5 feet
Step-by-step explanation:
The path traveled by a bottlenose dolphin as it jumps out of water is modeled by the equation,

where y is the height above water and x is the horizontal distance in feet.
If a beam of light is shone upward at an angle modeled by the equation

A beam of light hit the dolphin.
So, line must be intersect path of dolphin.
Using substation method,
Substitute y=10-x into dolphin equation.





Hence, The beam hit dolphin at 5 feet.
Answer:
x²
Step-by-step explanation:
Given the values x² and x^9
The greatest common factor is the factors common to two or more compared values :
Factors of :
x² = x * x
x^9 = x * x * x * x * x * x * x * x * x
Multiplying the Factors in both are : x * x = x²
Similarly :
___|x² | x^9
_ x | x | x^8
_ x | 1 | x^7
There is no factor which can reduce both further simultaneously, Hence the G. C. F = (x * x) = x²
Yes. x=3 and y =9 are the solutions.
Because if you change x=3 and y =9 ,you will have
3+2* 9 =21
3+18 =21
21 =21 (true)
is it 46 ??? because i did the work and don't feel like explaining
Answer:
0.245489 cubic meters.
Step-by-step explanation:
It is given that a firkin is an old British unit of volume equal to 9 gallons.
1 firkin = 9 gallons
6 firkins = 54 gallons
We need convert 6.00 firkins to cubic meters.
We know that,
1 gallon = 0.00454609 cubic meters
54 gallon = 0.24548886 cubic meters
6 firkins = 0.245489 cubic meters.
Therefore, 6.00 firkins is equivalent to 0.245489 cubic meters.
