Answer:
250x.04=x
Step-by-step explanation:
250x.04 would be 10 so you get a 10 doller return each year.
No, this is not a function because it does not have any equal values.
<span>Here you go:
1) Applying (a + b)² = a² + b² + 2ab,
(cosx + cosy)² = cos²x + cos²y + 2cos(x)*cos(y) and
(sinx + siny)² = sin²x + sin²y + 2sin(x)*sin(y)
2) ==> (cosx + cosy)² + (sinx + siny)² =
= (cos²x + sin²x) + (cos²y + sin²y) + 2{cos(x)cos(y) + sin(x)sin(y)}
= 2 + 2{cos(x - y)} = 2[1 + cos(x - y)]
= 2*2cos²{(x - y)/2} [Multiple angle identity, 1 + cos(2A) = 2cos²A]
= 4*cos²{(x - y)/2} [Proved]</span>
Discount %= 10%
Discount= x × 10%= x/10
Price after discount =x-(x/10)= 9x/10
But, given price after discount = rs 450
9x/10=450
9x=4500
x=4500/9= rs 500
<h3>
Answer:</h3>
2 is prime because it is a positive integer only divisible by itself and 1.
<h3>
Step-by-step explanation:</h3>
2 is the smallest prime.
A composite number is one that has more than one prime factor. 4 = 2·2 is composite, for example.
The number 1 is neither prime nor composite.
