sorry
Step-by-step explanation:
If you are moving the decimal point to the left, the exponent is negative. If you move it to the right, the exponent is positive.
There is only one negative exponent here, and it is the first option.
So:
A number is being written in scientific notation. The student moves the decimal point to the left 3 places and A<span>. multiplies by 10^-3.</span>
Answer:
6(10)+5x=180
Step-by-step explanation:
The grocery store received a crate of 180 pound...
So, the whole amount is 180..
The crate contains six 10 pound bag of potato plus an unknown number of 5pound bag of potato....
So if we think, that the unknown number is x the equation would be
6(10)+5x=180
Hope ya find this helpful..
This would be 50 rounded to the nearest ten
Answer:
Step-by-step explanation:
Note that the given height equation, which is a quadratic) has a graph that opens downward. Borrowing the quadratic formula, we find the roots of this equation, that is, the t values at which h(t) = 0:
The coefficients of this equation are a = -16, b = 80 and c = 0.
We need to find the roots of this quadratic. By the quadratic formula,
-(80) ±√(80² - 4(-16)(0) ) -80 ± 0
t = ------------------------------------- = ----------------- = -5/2 and -5/2 (seconds).
2(-16) -32
The initial height is 0 at t = 0 seconds and the final height 0 at 5/2 seconds.
