Answer:
Step-by-step explanation:
2x² - 7x - 3 = 1
Step 1: 2x² - 7x - 4 = 0
Step 2: incorrect.
Use Quadratic Formula to solve for roots.
x = [7 ± √(7² – 4·2(-4))] / [2·2]
= [7 ± √81] / 4
= [7 ± 9] /4
= -0.5, 4
The answer is option 2
Power = 175 hp
The correct formula to calculate the power is:
Power = weight * (speed / 234) ³
Where the weight is that of the vehicle plus the driver's
Therefore the calculation is as follows:
Power = (2200 + 180) * (98/234) ³
Power = 174.8266 hp
Rounding ...
Power = 175 hp
Answer:I believe it's true but I'm not sure
Step-by-step explanation:
The x-coordinate is 2 and y-coordinate is 12.
Substitute 2 into x then check if y is equal to 12.
D is the answer since y = (2) - 10 = -8, not 12.
In your question where ask to evaluate the function using calculator and then take its reciprocal and the function is cos(135). <span>Base on my calculation and through step by step procedure and with the guidance of the theories and by the use of formulas, I came up with an answer - sqrt of 2</span>
