Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
4.57 rounded to the nearest whole number is 5
Answer:
t = 13 over 25 or in alternate form its t = 0.52
The answer would be 8! This is because there were already five and then Jason got in, so six, and then two friends got in as well, so six plus two is eight!
If it is 5ft a minute then it must be 10ft every two minutes
