Step-by-step explanation:

Let x be the son's age. The father's age is 3x and 3x - x = 24.

Therefore 2x = 24 and x = 12.

The son's age is 12 and the father's age is 36 at present.

Approximate f by a Taylor polynomial with degree n at the number a. Step 1 The Taylor polynomial with degree n = 3 is T3(x) = f(

MAVERICK [17]

Answer:

If you center the series at x=1

$T_3(x) = e^2 + 4e^2 (x-1)+10(x-1)^2 + \frac{56}{3} e^2(x-1)^3 + R(x)$

Where $R(x)$ is the error.

Step-by-step explanation:

From the information given we know that

$f(x) = e^{2x^2}$

$f'(x) = 4x e^{2x^2}$ (This comes from the chain rule )

$f^{(2)}(x) = 4e^{2x^2} (4x^2+1)$ (This comes from the chain rule and the product rule)

$f^{(3)}(x) = 16xe^{2x^2}(4x^2 + 3)$ (This comes from the chain rule and the product rule)

If you center the series at x=1 then

$T_3(x) = e^2 + 4e^2 (x-1)+10(x-1)^2 + \frac{56}{3} e^2(x-1)^3 + R(x)$

Where $R(x)$ is the error.

Laura has $30 to spend on food for the week. Which inequality represents this? x < 30 x < 30 x > 30 x > 30

Llana [10]

X is less than or equal to $30, she can spend $30, she cant spend more, she can spend less.

The answer should look like X<30 with a line under the less than sign, i hope this helps.
