Answer:
= The exponent is 12
Step-by-step explanation:
(9.1 × 10^9)(7.5 × 10^2)
When multiplying terms in scientific notation, we multiply the numbers in front and add the exponents
(a* 10^b) (c* 10^d) = ac * 10^(b+d)
(9.1 × 10^9)(7.5 × 10^2) = (9.1*7.5) * 10^(9+2)
=68.25 * 10^11
But this is not proper scientific notation. We can only have 1 number in front of the decimal. We need to move the decimal 1 place to the right. That adds 1 to the exponent.
=68.25 * 10^11 = 6.825 * 10^(11+1)
= 6.825 * 10^12
Answer:
(0, 4)
Step-by-step explanation:
The y intercept will always be located at x=0. When x=0, y=4, so the y intercept would be written as (0, 4)
Answer:
Not sure if this is correct but it should be y=210x-140
Step-by-step explanation:
Anything greater than (1/5) that is positive
Ex. (1/4), (1/3), (1/2), 1, 2, 3, 4, 5
An obtuse angle because an obtuse is an angle that is greater than 90 degrees but less than 180.
