How do I simplify the n^-6*n^3 topic "Negative and Zero Exponents"

Mathematics
1 answer:
Alchen [17]3 years ago

Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3

n^-6 * n^3 = n^-3

If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.

n^-3 = n^-3 / 1 = 1/n^3

when the factor moves to the other side of the fraction, the side of the exponent changes.

Kuzi and Joanne live 130 km apart. They start travelling towards each other at the same time. If Kuzi covers 16 km every 2 hours
Zepler [3.9K]

Using the speed - distance relationship, the distance traveled by Joanne would be 55.714 km

Kuzi's speed :

  • <em>16</em><em>/</em><em>2</em><em> </em><em>=</em><em> </em><em>8km</em><em> </em><em>/</em><em> </em><em>hr</em><em> </em>

Joanne's speed :

  • <em>6km</em><em>/</em><em>hr</em><em> </em>

Let time taken = <em>t</em>

<u>Total</u><u> </u><u>distance</u><u> </u><u>traveled</u><u> </u><u>:</u>

8t + 6t = 130

14t = 130

t = 130/14

t = 9.2857142 hours

<u>Therefore, distance traveled by Joanne</u> :

Joanne's speed × time

6 km × 9.2857142 = 55.714 km

Therefore, distance traveled by Joanne will be 55.714 km

The graph of a line and and exponential intersect twice, once, or not at all. Describe the possible number of intersections of e
avanturin [10]

a) A line can intersect a parabola at 2 points, 1 point, or no points respectively. The only possible way at which it intersects at 1 point, would be if it were tangent to the parabola. [Check first attachment]

b) Two different parabolas can intersect at 2 points, 1 point or no points respectively. [Check second attachment]

It is possible for 2 parabolas to intersect at 4 and even 3 points. But one of the parabolas would be on it's side. You can consider those cases.

I think that you did it correctly, that's correct. 

<span>14.85 + 1.39x = 20
1.39x = 20 – 14.85
1.39x = 5.15
1.39 / 1.39 = 5.15 / 1.39
x = 3.70</span>
