Answer:
B
Step-by-step explanation:
One good way to look at this is to graph both polynomials, as shown in the picture. A tip to help graph is to factor it out and work from there. For example, in x²+14x+48, we can gather that (x+6)(x+8) is the same thing, and it is easier to then graph it. Similarly, for x²+12x+36, we can factor it out as (x+6)² .
When x²+12x+36 approaches 6, it is getting really close to 0, but it stays positive. When x²+14x+48 approaches 6 from the negative side, it is also getting close to 0, but it's negative. When x²+14x+48 approaches 6 from the positive side, it is positive.
Therefore, on the negative side, there is one positive and one negative (dividing a negative by a positive is negative, and a positive by a negative is also negative) , and on the positive side, there are two positives, forming one answer.The answer is therefore B
Answer:
The kilometers Jupiter travel in 5 seconds is <u>64 kilometers</u>.
Step-by-step explanation:
Given:
As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second.
1 mile is equal to 1.6 kilometers.
Now, to convert this speed to kilometers per second, and at this speed to find kilometers will Jupiter travel in 5 seconds.
So, to convert speed of miles per second into kilometres per second:
<em>1 mile = 1.6 kilometres.</em>
Thus, 8 miles = 8 × 1.6 = 12.8 kilometres per second.
Now, at this speed we calculate the kilometres Jupiter travel in 5 seconds by multiplying:
<em>In 1 second Jupiter travel = 12.8 kilometres.</em>
So, in 5 seconds Jupiter travel
Therefore, the kilometers Jupiter travel in 5 seconds is 64 kilometers.
