Q1- When you spent 24.1 minutes on the elliptical trainer and then did circuit training for 15.6 minutes, your fitness app says youburned 457.7 calories. When you spent 17.2 minutes on the elliptical trainer and 12.8 minutes circuit training you burned 379.8calories. How many calories did you burn for each minute on the elliptical trainer? How many calories for each minuteof circuit training?

a-This system has an infinite number of solutions.

b- This system has no solutions

c- calories burned on the elliptical trainer: 39.63, calories burned during circuit training: 31.74

d- calories burned on the elliptical trainer: 31.89, calories burned during circuit training: -1.65

e- calories burned on the elliptical trainer: 38.10, calories burned during circuit training: 29.52

f- calories burned on the elliptical trainer: -1.65, calories burned during circuit training: 31.89

Q2- What is the solution of the system of linear equations

3x + 4y + 2z = 3

4x + 10y + 2z = 9

a. (0.57 + -0.86t, -2.79 - -0.14t , t)

b. (-0.43, 1.07 , 2)

c. (-0.43 + -2.19t, t), t from negative infinity to positive infinity

d. (-0.43 + -0.86t, 1.07 - -0.14t, t), t from negative infinity to positive infinity

e. There are no solutions

f. (t, 2.43 + -0.86t, 1.07 - 0.04t), t from negative infinity to positive infinity

Q4- Consider the following system of linear equations

18.6x + 15.8y = 8.4

10.3x+1.2y = 9.6.

What is the elementary row operation needed to make the first entry in row 2 equal to zero?

a.R2 = 10.3R1 - 18.6R2

b.R2 = 10.3R1 + 18.6R2

c.R2 = -1.8R1 + 1.8R2

d.R2 = R1 - R2

e.R1 = R1 - R2

f.R1 = 10.3R1 + 18.6R2

Q5- What is the equation of the parabola that passes through the points (1, 8.4), (0, -1.3), (-1, -4.8)? As a reminder, the equation of a parabola is: y=ax2+bx+c

b.4.90x^2 + 13.20x + -1.3

c.3.10x^2 + 6.60x + -1.3

d.There is no such parabola

e.4.90x^2 + 6.60x + -1.3

f.3.10x^2 + 6.60x - -1.3
