Estimate the instantaneous rate of change at the point indicated. (Round your answer to four decimal places.) y(x) = 1 x + 2 ; x

Wittaler [7]

Answer:

-1/36

Step-by-step explanation:

Estimate the instantaneous rate of change at the point indicated

To find the instantaneous rate of change we find the derivative of the given function

Instantaneous rate of change is the rate of change at the given point

$f(x)=\frac{1}{x+2}$

To find derivative we apply power rule

$f(x)=(x+2)^{-1}$

$f'(x)=-1(x+2)^{-2}$

$f'(x)=\frac{-1}{(x+2)^2}$

Now plug in 4 for x in f'(x)

$f'(4)=\frac{-1}{(4+2)^2}$

$f'(4)=\frac{-1}{36}$

Find angles EFG pleaseee

Bumek [7]

Answer:

50 degrees.

Step-by-step explanation:

Angle FGE = $180-(7x+18)$ because angles on a straight line add up to 180 degrees.

Angle EFG = $180-38-(180-(7x+18))=6x-10$ (Angles in a triangle add up to 180)

$180-38-\left(-7x+162\right)=6x-10$

$180-38+7x-162=6x-10$

$7x-20=6x-10$

Add 20 to both sides:

$7x-20+20=6x-10+20$

$7x=6x+10$

Subtract 6x from both sides:

$7x-6x=6x+10-6x$

$x=10$

Angle $EFG=6x-10=6(10)-10=60-10=50$

Help please just answer would be fine

The amount of water decreases $16\frac{1}{2}$ pints in 12 weeks.

Solution:

The amount of water decreases in 7 weeks = $9\frac{5}{8}$ pints

The amount of water decreases each week is same.

Let us first change the mixed fraction into improper fraction.

$9\frac{5}{8}$ pints = $\frac{(9\times8)+5}{8}$

$=\frac{77}{8}$ pints

The amount of water decreases in 1 week

$$=\frac{\frac{77}{8} }{7}$

$=\frac{77}{8\times7}$

$=\frac{11}{8}$

So, the amount of water decreases in 1 week is $\frac{11}{8}$ pints.

The amount of water decreases in 12 week

$=\frac{11}{8}\times12$

$=\frac{132}{8}$

$=16\frac{4}{8}$

$=16\frac{1}{2}$ pints

Hence the amount of water decreases $16\frac{1}{2}$ pints in 12 weeks.
