A 4-column table with 5 rows. The first column is labeled age (years) with entries 1, 2, 3, 4, 5. The second column is labeled g
iven value with entries 15, 12, 9, 5, 4. The third column is labeled predicted value with entries a, 11.9, c, 6.1, 3.2. The fourth column is labeled residual with entries 0.2, b, 0, d, 0.8. John estimates the value of his car over time. The equation for the line of best fit is approximated as y = –2.9x + 17.7, where y represents the value, in thousands of dollars. What values complete the residual table? a = b = c = d =
To get the adjacent, we use the Pythagoras’ theorem which states that the square of the hypotenuse is equal the sum of the squares of the two other sides
Let the adjacent be x
4^2 = 3^2 + x^2
x^2 = 16-9
x^2 = 7
x = √7
The cosine is the ratio of the adjacent to the hypotenuse
The first thing to do is isolate the x so get rid of the -2.7 but since is a negative you are going to add it to 10.3 so>>> 2.7+10.3 =13 x≥13 is the answer.
