How to complete the table?

Y_Kistochka [10]

Answer:

-2.75

-1.75

-0.75

0.25

1.25

Step-by-step explanation:

The value of x is given in the top row of the table. We can complete the rest of the table by plugging in the corresponding values of x into the equation and solve for y.

For example:

y = (-2) - 3/4 = -2.75

y = (-1) - 3/4 = -1.75

y = (0) - 3/4 = -0.75

y = (1) - 3/4 = 0.25

y = (2) - 3/4 = 1.25

Ahat [919]

Answer:

The position is given by r(t) = (-2 -t √14, 1 + √3.5, 3 + 3√3.5)

Step-by-step explanation:

The direction is given by the difference between the starting point and the end point, thus it is (-4,0,6)-(-2,-1,3) = (-2,1,3). The norm of this vector is √( (-2)²+1²+3²) = √14 = 3.7416 secons

Since the speed is 7 cm/sec, we need to multiply this vector by 7/√14 = √3.5 in order to obtain how much does the particle advance each second.

As a consecuence, it advances (-2,1,3) * √3.5 = (- √14, √3.5, 3 √3.5)

And, as a result, the position after t seconds is given by the function

r(t) = (-2,1,3) + t (-√14, √3.5, 3 √3.5) = (-2 -t √14, 1 + √3.5, 3 + 3√3.5)

2. Decide which estimate is closest to the actual answer. Explain your reasoning.

sashaice [31]

Question A
take $100.80 divide it by 35 which would equal 2.88
so round that up for 3.0 for the closest answer

Question B
take 49.2 and divide it by 6 which would equal 8.2
so round it to the nearest number which would be 8.0

Question C
take 0.78 and divide it by 20L which would equal 0.039
so round that up to the closest number which would be 0.04L
