Answer:
length= 3.7 ft.
Step-by-step explanation:
T= (square root of length) * k
1.8 seconds = (square root of 3) * k
k= 1.8 seconds / (square root of 3)
a.) T= (square root of 11) k
substituting k:
T=(square root of 11) * 1.8 seconds / (square of 3)
T= 3.4 seconds
b.) 2 seconds = (square root of length) k
substituting k:
2 seconds =(square root of length) 1.8 seconds / (square root of 3)
Divide the equation by 1.8 seconds / (square root of 3):
2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)
10(square root of 3) / 9 = (square root of length)
square both sides:
100/7 ft= length
length= 3.7 ft.
Hope this helps.

Answer: D
80 000 > 0,00004
80 000 : 0,00004 = 2 000 000 000
2 000 000 000 = 2*10^9
Answer:
The Answer is D
Step-by-step explanation:
If the Exponent is 1 or just x then it is linear.
- If the Exponent is 2 or x^2 then it is quadratic
* If the Exponent has and x, then this graph is exponential because anything to the power of X is exponential.
1/2(1/2)=0.25^x
