The diameter would be twice 5, or 10
Answer: $10
Step-by-step explanation:
Assume the price of the phone case is x.
Assume the price of the charging cord is y.
Discounted price for phone case : 15% * x
= 0.15x
Discounted price for charging cord = 0.15y
Expression is therefore:
0.15x + 0.15y = 4.20
0.15 * 18 + 0.15y = 4.20
2.7 + 0.15y = 4.20
0.15y = 4.2 - 2.7
y = 1.5/0.15
y = $10
decimal from 6.0250 to 60250. is moving it four decimal places, so that is the same as multiplying by 1 followed by four zeros). This means that an equivalent fraction is 60250 / 10000.
Use the rational roots test. The possible roots are: plus/minus 6,3,2,1
Use synthetic division and you will see that 3 is a root:
3 | 1 -3 -3 11 -6
| 3 0 -9 6
____________
1 0 -3 2 0
Use rational root again, to see that possible roots are: plus/minus 2,1
Try 2:
2 | 1 0 -3 -2
| 2 4 2
_____________
1 2 1 0
The above is x^2+2x+1 which is a perfect square: (x+1)^2
So we have the final factorization: (x-3)(x-2)(x+1)^2
So the roots are: 3, 2, -1
Where -1 is a double zero.
Answer:
Answer to this question depends on the person answering the question.
Step-by-step explanation:
The set of statements that Neil made he might have tried to indicate that mathematics is no less than reading itself. Math is a beautiful language and he is trying to advocate that like people compel on reading, people should also compel learning mathematics up to a certain extent. People should try to discover the beauty of mathematics.
When people in general say that they are bad at mathematics they might mean they are not good at basic math or they might also mean that they are not good in advance mathematics. Since the field of advance mathematics or applied mathematics does not come in to play in the common life therefore, people in general think that is it okay to say that they are bad at math.
For an instance advance math which is behind the design of jet engine, plane engine, math behind the architecture of a building is hidden from the vision of common people and neither they are interested. So I believe for them it is okay to say that they are bad at math.
But if one is curious to learn and apply mathematics, then it certainly is not okay to say that he/she is bad at math.
