Answer:
x = 40
Step-by-step explanation:
Since FG and HI are parallel and BC is a transversal, then
∠ GBE and ∠ GBE are same side interior angles and are supplementary, thus
3x + 20 + x = 180, that is
4x + 20 = 180 ( subtract 20 from both sides )
4x = 160 ( divide both sides by 4 )
x = 40
Suppose he makes the payment with two equal annual instalments, the present value of the amount he is owing is $1,543 , the interest rate is 23.76% = 0.2376.
The amount of payment he makes in two of the periodic payments is given by:

Therefore, in 2 years, the amount he has paid for the tools is 2(1,056.20) =
2,112.40
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.
