If m ≤ f(x) ≤ M for a ≤ x ≤ b, where m is the absolute minimum and M is the absolute maximum of f on the interval [a, b], then

agasfer [191]

Answer:

smaller value is 1.2

larger value is 6

Step-by-step explanation:

$f(x)=\frac{3}{1+x^{2} }$

when x=a=0, one has

$f(0)=\frac{3}{1+0^{2} } \\f(0)=3$

now, when x=b=2, one has

$f(2)=\frac{3}{1+2^{2} } \\f(2)=\frac{3}{5}$

Therefore, the absolute minumun is

$m=\frac{3}{5}$

and the absolute maximun is

$M=3$

The approximation to the integral is

$\frac{3}{5}(2-0)\leq \int\limits^2_0 {f(x)} \, dx \leq 3(2-0)$

hence

$\frac{3}{5}(2)\leq \int\limits^2_0 {f(x)} \, dx \leq 3(2)\\\frac{6}{5} \leq \int\limits^2_0 {f(x)} \, dx \leq 6\\1.2 \leq \int\limits^2_0 {f(x)} \, dx \leq 6$

Molly is converting 2 yards to millimeters. Will the number of millimeters be fewer than or greater than 2?

ololo11 [35]

Greater than.

yards are a larger unit of measurement, so to convert it there are more millimeters to count the same amount of space.

The blood alcohol (C2H5OH) level can bedetermined by titrating a sample of blood plasma with an acidicpotassium dichromate solut

NISA [10]

Answer:

Step-by-step explanation:

In acidic reaction , equivalent weight of potassium dichromate is

mol weight / 6

= 294 / 6

49 g

equivalent weight of alcohol = 46 g

31.05 cc of .06M of potassium dichromate

= 31.05 x .06 cc of M potassium dichromate

= 1.863 cc of M potassium dichromate

= 1.863 x 6 cc of N potassium dichromate

= 11.178 cc of N potassium dichromate

== 11.178 cc of N alcohol

= (11.178 / 1000 ) x equivalent weight of alcohol

= (11.178 / 1000 ) x 46 g

= .514 g

30 g of blood contains .514 g of alcohol

100 g of blood contains (0.514 / 30) x 100

= 1.71 % of alcohol.

Answer:

42.5

Step-by-step explanation:

those two dashes or lines on the sides of the tringle or between A and B or A and C mean that those line are the same length so I would guess your answer is the same as the other givin length which is 42.5
