Answer:

The correct answers are A, C and D.

Step-by-step explanation:

Given the equation 4x - 5y = 24, we substitute the coordinates of the given points to determine whether the equation is then true or not true.

For example, if we focus on point B:  (6, 0), x = 6 and y = 0 and the equation becomes 4(6) - 5(0) = 24, which is TRUE.

Doing the same thing with A:  (-9, -12), we get 4(-9) - 5(-12) = 24, which is also TRUE.

Check out C:  (4, 8):  4(4) - 5(8) = 24.  This is FALSE.

Check out D:  (1, -4):  4(1) - 5(-4) = 24.  This is TRUE.

The correct answers are A, C and D.

If we approximate the function y=sin(x) with a0+a1 x a2 x^2 +a3 x^3, what is a0,a2,a2,a3?
Rashid [163]

The coefficients a_0,a_1,a_2,a_3 could be chosen to be the coefficients in the Maclaurin series of \sin(x).

We have

y = \sin(x) \approx a_0 + a_1 x + a_2 x^2 + a_3 x^3 \\\\ \implies y(0) = 0 = a_0

y' = \cos(x) \approx a_1 + 2a_2 x + 3a_3 x^2 \\\\ \implies y'(0) = 1 = a_1

y'' = -\sin(x) \approx 2a_2 + 6a_3 x \\\\ \implies y''(0) = 0 = 2a_2

y''' = -\cos(x) \approx 6a_3 \\\\ \implies y'''(0) = -1 = 6a_3

It follows that a_0=0, a_1=1, a_2=0, and a_3 = -\frac16.

Lisa [10]

Answer:

SA = 69.6in²

V = 28.8in³

Step-by-step explanation:

SA = 8 × 1.5 × 2 + 8 × 2.4 × 2 + 2.4 × 1.5 × 2 = 69.6in²

V= 8 × 1.5 × 2.4 = 28.8in³
