g and Consider the following. f(x) = 4x2 + 5x − 18 (a) Find the instantaneous rate of change of the function at the value x = −4

Oduvanchick [21]

Answer:

a) $\frac{dy}{dx} = -27$ , b) $m = -27$

Step-by-step explanation:

a) The instantaneous rate of change is:

$\frac{dy}{dx} = 8\cdot x + 5$

$\frac{dy}{dx} = 8\cdot (-4)+5$

$\frac{dy}{dx} = -27$

b) The slope of the tangent line is equal to the instantaneous rate of change found previously.

$m = -27$

PLEASE HELP!!!

Sholpan [36]

P=12T

Q=66T

-----------

Toys added to each bag:

P=12T+nT

Q=66T+nT

Therefore, 66T+nT=3(12T+nT)

------------

66T+nT=36T+3nT

T(66+n)=T(36+3n)

66+n=36+3n

3n-n=66-36

2n=30

Therefore, n=30/2=15

*She added 15 toys to each bag.
