What is the weight in grams of a liquid that exactly fills a 202.0 mL container if the density of the liquid is
Otrada [13]
The weight of a liquid is: 138.37 grams.

step-by-step explanation:

we are given that the volume of the container=202 ml(milliliter).
also the density of the liquid is given =0.685 grams over milliliter.
we know that the mass or weight of the liquid is given by:
weight=density×volume .
weight=(0.685×202) grams.
weight=138.37 grams.
hence, the weight of liquid that exactly fills a 202.0 milliliter container is 138.37 grams.

Find the indicated quantities for y equals f (x )equals 3 x squared. ​(A) Simplify StartFraction f (3 plus Upper Delta x )minus
torisob [31]

Answer:

6x

Step-by-step explanation:

Given that a function f(x) is given as

y=f(x) = 3x^2

A) f(x+ \Delta x) = 3((x+ \Delta x)^2=3(x^2+2x \Delta x+\Delta x^2)\\f(x) = 3x^2\\f(x+ \Delta x) -f(x) = 6x  \Delta x +\Delta x^2

Now divide by delta x

\frac{f(x+ \Delta x) -f(x)}{\Delta x}\\=6x+\Delta x

B) When delta x tends to 0, this becomes

6x

(NOte: This is the derivative of f(x))

The aorta is the largest artery in the human body. In the average adult, the aorta attains a maximum diameter of about 1.18 inch
Sholpan [36]
Well we know that 1 inch is 2.54 cm.  But how wide is .18?  Lets do .18 x 2.54 to get 0.4572.  Now lets add 2.54 + 0.4572 to get 2.9972.  This means that the maximum width of the aorta is 2.9972 cm.  Hope this helped :)
