Answer:
The height at time of 12.1 seconds is approximately 729.2562 feet
Step-by-step explanation:
The general form of the quadratic regression equation is y = A + Bx + Cx²
The quadratic regression formula is given as follows;
Solving using an online quadratic regression calculator, gives;
A = 2.5643259
B = 246.6374865
C = -15.41986006
Substituting gives;
y = 2.5643259 + 246.6374865·x -15.41986006·x²
When time, x = 12.1, we have;
y = 2.5643259 + 246.6374865×12.1 -15.41986006×12.1²≈ 729.2562 feet
The height at time of 12.1 seconds ≈ 729.2562 feet.
Answer:
10 amps.
Step-by-step explanation:
According to Ohm's Law, V=IR, and, dividing both sides by R, we have , where V is the amount of volts, R is the amount of resistance, and I is the current in amps.
Plugging the values into the formula, we have .
Therefore, there is 10 amps of current in the circuit.
