The distance is 65 because -48 plus 17 equals 65.
I believe it is 75% because he is selling them for $3 more than what he bought them for and bought them for $4 and 3 is 75% of 4, sorry if i'm wrong
Answer:
=2*3^2 *7
Step-by-step explanation:
Prime factorization means to simplify 126 down to prime numbers
126 = 2*63
= 2* 9*7
= 2*3*3*7
Since 2 3 and 7 are prime numbers, we rewrite these with exponents
=2*3^2 *7
Answer:
Step-by-step explanation:
(a) 
Suppose 
by differentiation;

Suppose n = 3
Then, the integral




recall that 
Then;

(b) 
suppose; 



If n = u, then the integration is:




Since; 
Then;

(c) 
Suppose 
Then, by differentiation of both sides


Suppose n = 4 in integration, then:

By substitution;



<u>Answer:</u>
y = 122.57
<u>Explanation:</u>
y = 143 when x = 49
Y varies directly with x, so the equation is --> y = kx (k would be the constant of variation).
k = y/x = 143/49
y = (143/49) x
When x = 42 --> y = (143/49) · 42 --> y = 2.92 · 42 --> y = 122.57
