Which pair of angles shares ray A.F as a common side? DAF and DAB EAF and CAE BAF and EAD BAF and FAD
shtirl [24]

Answer:

BAF and FAD

Step-by-step explanation:

In order for an angle to have A.F as a side, it must have the letters A.F or FA in its name.

In DAF, the angle is made of rays AD and A.F.  In DAB, the angle is made up of rays AD and AB.  This is not the correct pair.

In EAF, the angle is made of rays AE and A.F.  In CAE, the angle is made up of rays AC and AE.  This is not the correct pair.

In BAF, the angle is made of rays AB and A.F.  In EAD, the angle is made up of rays AE and AD.  This is not the correct pair.

In BAF, the angle is made up of rays AB and A.F.  In FAD, the angle is made up of rays A.F and AD.  This is the correct pair.

Help! How Can I Determine the interval in which the function is increasing.
Anuta_ua [19.1K]

Answer:

(2,\infty)

Step-by-step explanation:

After x=2, we see that the change in y over the change in x is positive since both variables increase with each other, so (2,\infty) is where the function is increasing.

Find the value of 1415×211 Although these numbers aren't quite as nice as the ones from the example, the procedure is the same,
BabaBlast [244]

Answer:

298565

Step-by-step explanation:

Given problem,

1415 × 211

∵ Direct multiplication is quite tough so we can split the number into smaller one for making the multiplication easier,

= (1400 + 15) × (210 + 1)

By using distributive property,

= 1400 × (210 + 1) + 15(210 + 1)

Again by distributive property,

= 1400 × 210 + 1400 + 15 × 210 + 15

Simplifying,

=  294000 + 1400 + 3150 + 15

= 298565

Hence, 1415 × 211 = 298565
