Verify whether the indicated numbers are zeroes of their corresponding polynomials.

Mashcka [7]

Answer:

No, incorrect

Step-by-step explanation:

Given

Q(s) = -4s^3 + 7s^2 - 24;
s = -4 and 1

Verifying zeroes

Q(-4) =

-4(-4)^3 + 7(-4)^2 - 24 =
256 + 112 - 24 =
344
Incorrect as 344 ≠ 0

Q(1) =

-4(1)^3 + 7(1)^2 - 24 =
-12 + 7 - 24 =
-29
Incorrect as -29 ≠ 0

If f(x)=e^2x(x^3+1) then f'(2)=

qaws [65]

Answer:

See below

Step-by-step explanation:

$f(x)=e^2x(x^3+1) = e^2x^4+x$

Considering

$f'(x)=\dfrac{d}{dx}f(x)=\dfrac{d}{dx}e^2x^4+\dfrac{d}{dx}x$

Once the derivative of a constant is 1 and $e^x = \dfrac{d}{dx} e^x$

Then,

$\dfrac{d}{dx}f(x)=\dfrac{d}{dx}e^2x^4+\dfrac{d}{dx}x =\boxed{ e^2 4x^3+1}$

Therefore,

$f'(2) = e^24\cdot 2^3 +1 = 32e^2+1$
