If the temperature drops, then you must have subtract amount of drop from initial temperature.
$-12,3^o-6,8^o=-(12,3^o+6,8^o)=-19,1^o$

The correct answer is the first one.

Use the definition of a derivative to find f’(x).

tatyana61 [14]

Answer:

f'(x) = $-\frac{9}{x^2}$

Step-by-step explanation:

i) f(x) = 9 / x

ii) f'(x) = $$\lim_{h\to 0} \frac{f(x+h) - f(x)}{h} $ \hspace{0.2cm}$

$= $\lim_{h\to 0} \frac{\frac{9}{x+h} - \frac{9}{x} }{h} = \hspace{0.1cm} $\lim_{h\to 0} \frac{9x - 9(x+h)}{hx(x+h)} $ \hspace{0.1cm} = \hspace{0.1cm}$\lim_{h\to 0} \frac{-9h}{hx(x+h)} = $\lim_{h\to 0} \frac{-h}{x(x+h)} = \frac{-9}{x^2}$$

Which illustrates the construction of a perpendicular to a line from a point on the line?

quester [9]

I believe the correct answer from the choices listed above is the last option. The last option clearly describes the illustration of the construction of a perpendicular to a line from a point on the line where you start on a point in the line. Using an arbitrary radius, draw arcs intersecting the line <span> at two points. </span>
Hope this answers the question. Have a nice day.

14 gal/s =_qt/minutes

3241004551 [841]

We know that 1 gallon= 4 quarts
therefore, 14 gallons=56 quarts
so
14gallons/s=56 qt/s

if we would need to find just gallons/second in quarts /second the answer will be simple, but we need to find the answer in qt/min
is there are 56 qt per second, it means that it will be
56*60 in 1 minute
56*60=3360
final answer
14 gallons/s=3360 qt/min
