Answer:

Table shows a direct variation.

Step-by-step explanation:

For the direct variation equation representing the table will be in the form of,

y = kx

Where 'k' is the proportionality constant.

From the table attached,

For x = -10 and y = -20,

-20 = k(-10)

k = 2

For x = 1 and y = 2

2 = k(1)

k = 2

For x = 2 and y = 4,

4 = 2k

k = 2

For all points given in the table 'k' is same or constant.

Therefore, relation represented by the table shows a direct variation.

Answer:

4x² -29x +51

Step-by-step explanation:

Put x-3 where x is in the original function definition, then "simplify". I think you'll find it convenient to rewrite the original function definition first.

... g(x) = 4x² -5x = x(4x -5)

Substituting, we have

... g(x-3) = (x -3)(4(x -3) -5)

... = (x -3)(4x -17) . . . . . simplify right factor

... = 4x² -12x -17x +51

... g(x -3) = 4x² -29x +51

Find the percentage error |sinθ - θ|/sin(θ)*100 this approximation introduces for an angle of 0. 020 radians.
Elza [17]

Considering the given angle and the given formula, it is found that the percentage error for an angle of 0.02 radians is of 0.0067%.

<h3>What is the percentage angle for an angle?</h3>

For an angle \theta, it is given by the following formula:

P = 100\frac{|\sin{\theta} - \theta|}{\sin{\theta}}

In this problem, the angle is of \theta = 0.02, hence:

P = 100\frac{|\sin{0.02} - 0.02|}{\sin{0.02}}

P = 0.0067

The percentage error for an angle of 0.02 radians is of 0.0067%.

If g(x) = x3 - 5 and h(x) = 2x - 2, then h(g(-2))= ?
mixas84 [53]
Please, write "x^3" for "the cube of x," not "x3."  "^" denotes exponentiation.

Then you have g(x) = x^3 - 5 and (I assume) h(x) = 2x - 2.

1)  evaluate g(x) at x = -2:  g(-2) = (-2)^3 - 5 = -8 - 5 = -13

2) let the input to h(x) be -13:  h(-13) = 2(-13) - 2 = -28 (answer)
