Answer:

1.26 * 10 ^6

Step-by-step explanation:

1260000

Scientific notation is of the form a* 10 ^b

where a is a number between 1 and less than 10

Move the decimal 6 places to the left

1.26 ( dropping the extra zeros)

b = +6 since we moved the decimal 6 places)

1.26 * 10 ^6

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Note ∠ Q is a right angle = 90°

Sum the angles and equate to 180

7b + 14 + 6b + 11 + 90 = 180, that is

13b + 115 = 180 ( subtract 115 from both sides )

13b = 65 ( divide both sides by 13 )

b = 5

Thus

∠ R = 6b + 11 = 6(5) + 11 = 30 + 11 = 41°

∠ S = 7b + 14 = 7(5) + 14 = 35 + 14 = 49°

∠ Q = 90°

4. The formula v= 64h gives the velocity v in feet per second of an object that

user100 [1]

The velocity when the object falls from 84 feet is 73.32 ft/sec

Step-by-step explanation:

The formula is derived from the conversion of energy principle. As the object falls the potential energy changes into kinetic energy. The right formula is:

$v=\sqrt{64h}$

here,

v represents the velocity

and

h represents the height in feet.

We can plug in the value of height in the formula to get the value of velocity

So, Putting h=84

$v=\sqrt{64*84}\\=\sqrt{5376}\\=73.3212\ ft/sec$

Rounding off to nearest 100th

v=73.32 ft/sec

The velocity when the object falls from 84 feet is 73.32 ft/sec
