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 =
The values that complete the residual table a, b, c, d are as follows:
a = 14.8, b = 0.1, c = 9, d = -1.1What is the equation of a straight-line graph?A straight-line graph takes the form y = mx + c, in which (m) refers to the gradient, (y) is the intercept, and (c) is the starting value when (x) is zero.
So, from the given information:
y = -2.9x + 17.7 --- (1)So, to estimate the value of (a) in the table, we have to replace (y = a) and (x = 1) in equation (1).
i.e.
a = -2.9(1) + 17.7a = 14.8To estimate the value of (b), we need to subtract the given value(12) from the predicted value (11.9)
b = 12 - 11.9b = 0.1To estimate the value of (c), we need to replace (y = c) and (x = 3) in equation (1).
c = -2.9(3) + 17.7c = -8.7 + 17.7 = 9To estimate the value of (d), we need to subtract the given value and predicted value.

A body moving in the positive x direction passes the origin at time t = 0. between t = 0 and t = 1 second, the body has a constant speed of 24 meters per second. at t = 1 second, the body is given a constant acceleration of 6 meters per second squared in the negative x direction. the position x of the body at t = 11 seconds is
Integrate over [0, 1] to get the position of the body after 1 second. It starts at the origin, so we take x(0 s) = 0 m and using the fundamental theorem of calculus,
[tex]\displaystyle x(1\,\mathrm s) = x(0\,\mathrm s) + \int_{0\,\rm s}^{1\,\rm s} \left(24\frac{\rm m}{\rm s}\right) \, dt = 24 \, \mathrm m[/tex]
Then for time t ≥ 1 second, we integrate over [1, 11] to get the position after the next 10 seconds of motion. Since x(1 s) = 24 m, we have
[tex]\displaystyle x(11\,\mathrm s) = x(1\,\mathrm s) + \int_{1\,\rm s}^{11\,\rm s} \left(24\frac{\rm m}{\rm s} - \left(6\frac{\rm m}{\mathrm s^2}\right) t\right) \, dt = \boxed{-36\,\mathrm m}[/tex]
Without using calculus, in the 1st second of motion the body travels at constant speed, so it reaches a new position of
x = (24 m/s) (1 s) = 24 m
In the next 10 seconds, the body has constant acceleration and its velocity at time t is
v = 24 m/s - (6 m/s²) (t - 1 s)
so its "initial" velocity is 24 m/s, and after 10 seconds it attains a "final" velocity of
24 m/s - (6 m/s²) (11 s - 1 s) = -36 m/s
Then the body travels a distance x such that
(-36 m/s)² - (24 m/s)² = 2 (-6 m/s²) x ⇒ x = - 60 m
and so the body's net change in position is 24 m - 60 m = -36 m.

20.3 applying the zero product property to solve equations
Explanation:
The zero product property allows us to factor equations and solve them. For instance, x² - 6x + 5 = 0 or (x - 1) (x - 5) = 0. With the zero product property, (x - 1) = 0 or (x - 5) = 0. As a result, the answers are x = 1 and x = 5.

The Vikings were infamous for setting ambushes and hiding out in wooded areas to wait for advancing troops along established roadways.

Building sheep pens : darsh and darpan are fencing off a large rectangular area to build some temporary holding pens. to prep the males, females, and kids, they are separated into three smaller and equal-size pens partitioned within the large rectangle. (i) if 384 ft of fencing is available and the maximum area is desired, what will be the dimensions of the larger, outer rectangle? (ii) what will be the dimensions of the smaller holding pens?
The dimensions of the larger outer rectangle and smaller holding pens are respectively; 96ft x 96ft and 31ft x 96ft
How to maximize Functions?Let the side lengths of the big rectangle be x and y. Thus the area of the big triangle is; A = xy
If the fencing available is 384 ft, then perimeter is 384 ft. Thus;
2x + 2y = 384
y = (384 - 2x)/2
y = 192 - x
Putting 192 - x for y in A gives us;
A = x(192 - x) = 192x - x²
Completing the square to rearrange the equation of A gives us;
A = 9216 - (x - 96)²
If A is to be a maximum, then;
x - 96 = 0
x = 96 ft
y = 192 - 96 = 96 ft
Since we maximised the area of the bigger rectangle , we have maximised the area of the smaller pens. The dimensions of the smaller holding pens will be;
x' = 96 ft /3 = 31 ft
y' = 96 ft
