To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.
3% is the decimal 0.03 .
To make a number 3% bigger, multiply it by 1.03 .
The ' 1 ' part is the amount that's already there, and
the ' .03 ' part is the amount to be added onto it.

Step-by-step explanation:
I believe
30% is bigger than

.
To find the answer, you'd have to convert both the fraction and the percent into decimal form to see which one is truly bigger. Converting the percent is fairly easy. 30% would become 0.30 is decimal form. To find the fraction in decimal form, you'd have to divide the numerator by the denominator, which would be
4 ÷ 15, which makes :
2.6666666666666666666666667.
Now you compare easily. Which one is bigger?
2.666666666666666666666667 or
0.30?
0.30 is bigger. So 30% is bigger out of both of them.
Answer:
=14n⁴+8n²-9n+7
Step-by-step explanation:
(8n⁴-6n+8n²)+(6n⁴-3n+7)
=8n⁴-6n+8n²+6n⁴-3n+7
=8n⁴+6n⁴+8n²-6n-3n+7
=14n⁴+8n²-9n+7
