Answer: We are using a line regression tool to solve the parameters asked in the problem. We can use online tools or that of Excel. According to the tool, the best fit values are

Slope0.3848 ± 0.03956

Y-intercept0.6053 ± 0.6370

X-intercept-1.573

1/Slope2.598

Step-by-step explanation: Best fit lines make sure that the standard deviation at each point is minimum from the best fit line.

Use polynomial long division to find the quotient and the remainder when 2x^3-3x^2-2x-1 is divided by x-3
Alexxx [7]

Answer:

  • quotient: 2x^2 +3x +7
  • remainder: 20

Step-by-step explanation:

See the attachment.

At each step, the value being subtracted from the dividend is the product of the quotient term and the divisor. The quotient term is found by dividing the highest-degree term of the dividend by the highest degree term of the divisor (x).

When the dividend has a degree that is less than the degree of the divisor, we call that value (20) the remainder.

Brian is traveling at a rate of 72.0 meters/second. What speed would he be traveling in miles/hour?
Korvikt [17]

Answer:

we know that, 1miles/hour = 0.45m/s

or, 1meters/second = 1/0.45

1m/s = 2.22222222222

Step-by-step explanation:

Then,

72.0 meters/second = 72.0*2.22222222222

                                  =160 miles per hour.

erastovalidia [21]

Answer:

2 complex conjugates

Step-by-step explanation:

The discriminate is the part of the quadratic formula that is under the radical sign.  If the discriminate is negative, that means that the solutions, both of them, are complex conjugates, aka imaginary solutions.
