The expression 6.7 times 1.45^t models the number of billions of genetic sequence bases available in the public database of the Whole Genome Shotgun project t years since 2002.
What does 1.451.451, point, 45 represent in this expression?
Choose 1
A. It is 1.45 years since 2002.
B. There were 1.45 billion bases in the database in 2002.
C. The number of bases in the database is multiplied by 1.45 each year.

Step-by-step explanation:

The number of bases in the database is multiplied by 1.451.451, point, 45 each year.

the number bases in the database is multiplied by 1.45 each year

Step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

answer4 to the second power is 16

and 4 to the third power is 64,
