Answer:

D

Step-by-step explanation:

To answer this question, we have to define to bisect an angle:

To bisect an angle is to divide it into two equal parts, we can call those as congruent parts because these have the same area.

So it is crucial: we need to keep it proportionally divided when we start to construct an angle bisector.

Examining the alternatives, there is only one correct:

--

D. So now let's place the compass needle on the vertex of the angle, and draw an arc across both legs of the angle. True

The reason to proceed this way as our first step is the proportional division made by the inner line that bisects the angle. Thus in the first step, we pave the way to trace another arc in the middle of the inside area. Done with the same width and compass needle on the marks. Finally, the line to vertex crossing the mark.

Use identities to find the values of the sine and cosine functions for the following angle measure.

puteri [66]

Using the cosine double angle formula,

$\cos 2\theta=2\cos^2 \theta-1=\frac{12}{13}\\\\2\cos^{2} \theta=\frac{25}{13}\\\\\cos^{2} \theta=\frac{25}{26}\\\\\boxed{\cos \theta=\frac{5}{\sqrt{26}}}$

(Note I took the positive case since $\theta$ terminates in the first quadrant)

Using the Pythagorean identity,

$\sin^2 \theta+\cos^2 \theta=1\\\\\sin^2 \theta+\frac{25}{26}=1\\\\sin^2 \theta=\frac{1}{26}\\\\\boxed{\sin \theta=\frac{1}{\sqrt{26}}}$

(Note I took the positive case since $\theta$ terminates in the first quadrant)

How do you do this question?

raketka [301]

Answer:

The required relation is,

$\frac {dV}{dt}$ = $c{\frac{dT}{dt}}$

Step-by-step explanation:

We know that for a certain amount of dry gas when the pressure is kept constant it's volume V and temperature T is related by the function,

V = cT -----------------------(1) [where "c" is a constant]

So, in that case rate of change of volume(V) with respect to time (t),

= $\frac {dV}{dt}$

will be equal to ,

$c{\frac{dT}{dt}}$

where $\frac {dT}{dt}$ is equal to rate of change of temperature (T) with respect to time (t) and c is the constant stated before.

So, the required relation is,

$\frac {dV}{dt}$ = $c{\frac{dT}{dt}}$

Big Smiles Toy Company needs to pack marbles into a box. The company has two boxes they can use. Box A is 9 inches wide, 13 inch

shtirl [24]

Answer:

Big Smiles Toy Company should choose Box B as its volume is 82.5 $inch^3$ larger than Box A

Step-by-step explanation:

Given

Dimension of Box A= 9 inches width, 13 inches length, 11.5 inches height

Dimension of Box B =14 inches width, 8.5 inches length, 12 inches height

Volume of Box A= Length $\times$ width $\times$ height= $9\times13\times11.5= 1345.5 inches^3$

Volume of Box B =Length $\times$ width $\times$ height= $14\times8.5\times12= 1428 inches^3$

Difference = Volume of Box B - Volume of Box A = 1428 - 1345.5 = 82.5 $inches^3$

Box B has 82.5 $inch^3$ volume larger than Box A
