Answer:
92,960,000
Step-by-step explanation:
When multiplying by 10 to the power of something. You can just add move the decimal point "n" times to the right. (where n is the exponent over 10)
For example:
1.23456 * = 123.456 (the decimal point moved <u>2</u> steps to the right)
4 * = 40000 (the decimal point moved <u>4</u> steps to the right)

If y is inversely proportional to 1/roots then:
Y= k/root x
Find the value of the constant k
When y=7 and x=64
7=k/8
k= 56 (7x8)
When y=8
8=k/root x
Root x = k/8 since we know k = 56
Root x= 56/8
Square both sides
x=49
.3 (100) = moving the decimal to the right 2 times because of the two zero's in '100'
So .3 (100)= 30
Answer:
2 seconds and 38 seconds
Step-by-step explanation:
h=-16t²-vot
1,200=-16t²-640t
turn this into standard form
16t²-640t+1200=0
now plug thes numbers into the quadratice formula
a 16 b -640 c 1200
solve with quadratic formula to get ≅2 and ≅38 seconds
Answer
4(y - 6)
Explanation
The difference of y and 6 can mathematically be represented as y - 6.
Therefore, four times the difference of y and six will be 4(y - 6).
