8.71 xx10^(12)
The exponent is a positive number. This means the decimal point moves to the right by the number of the exponent.
There are two digits to the right of the decimal point, so to move the decimal 12 places, you would need to add 10 zeros.
8.71 x 10^12 becomes 8,710,000,000,000.
Answer:
(x+12)(x+5)
Step-by-step explanation:
Formula use: a²+bx+c
- Make one side equal to zero:
Original:
-7x-60 =x² +10x
New:
x² + 17x + 60
New:
(1)x x 60 = 60
- Find factors of 60 that when added, equal to 17.
New:
10 × 6, 60 × 1, 20 × 3, <u>5 × 12</u>, 4 × 15
5 times 12 equal 60, but when added equal to 17.
- Replace the 17 with 5 and 12
New:
x² + 5x + 12x + 60
- Break them off into two equations
New:
x² + 5x l 12x + 60
- Divide each equation into it's simpilest form. Make sure the numbers in the ( ) are the same.
New:
x(x + 5) l +12(x+5)

A = velocity / time
b) 40m/s
13m / 3s = 4.33 m/ss
