Answer:

The change is negative, since the volume in the final state is smaller than the volume in the initial state. 2.25 We express V for the ideal gas as a function of T , p and n: V (T , p, n) = ... each smooth part of the curve and add the integrals, used up yearly by living organisms, which means that even if the oxygen supply was.

Calculate the volume of the composite shape<br> please please help giving brainliest!!

Ilya [14]

${\qquad\qquad\huge\underline{{\sf Answer}}}$

There are two hemispheres in there with radius 3 cm, so we can consider it as a whole one. and the other shape in between is Cylinder with radius 3 cm and height 4 cm.

Volume of whole ahape = volume of Cylinder + volume of sphere ~

<u>Volume</u> <u>of</u> <u>sphere</u> :

$\qquad \sf \dashrightarrow \: \cfrac{4}{3} \pi {r}^{3}$

$\qquad \sf \dashrightarrow \: \cfrac{4}{3} \sdot3.14 \sdot {(3)}^{3}$

$\qquad \sf \dashrightarrow \: (4 )\sdot(3.14) \sdot(9)$

$\qquad \sf \dashrightarrow \: 113.04 \: \: cm {}^{3}$

<u>Volume</u> <u>of</u> <u>Cylinder</u> :

$\qquad \sf \dashrightarrow \: \pi {r}^{2} h$

$\qquad \sf \dashrightarrow \: 3.14 \cdot(3) {}^{2} \sdot4$

$\qquad \sf \dashrightarrow \: 3.14 \sdot(9) \sdot(4)$

$\qquad \sf \dashrightarrow \: 113.04 \: \: cm {}^{3}$

<u>Volume</u> <u>of</u> <u>whole</u> <u>shape</u> :

$\qquad \sf \dashrightarrow \: 113.04 + 113.04 = 226.08 \: \: cm {}^{3}$

$\qquad \sf \dashrightarrow \: 226.08 \: \: cm {}^{3}$

In ΔDEF, the measure of ∠F=90°, FE = 21, DF = 20, and ED = 29. What is the value of the cosine of ∠E to the nearest hundredth?

luda_lava [24]

Answer:

43.60°

Step-by-step explanation:

We can solve the triangle using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,

Sin Ф = opposite side/hypotenuses side

Cosine Ф = adjacent side/hypotenuses side

Tangent Ф = opposite side/adjacent side

The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.

Considering triangle ΔDEF, where ∠F=90°, FE = 21, DF = 20, and ED = 29

As such, with respect to angle E, ED is the hypotenuse, DF is the opposite side and FE is the adjacent side

Cosine ∠E = 21/29

∠E = cos-1 0.724137931

∠E = 43.60° to the nearest hundredth
