For this question, we can divide both numbers by 8, as they are both divisible by 8. Then, we will be left with our answer, which will be a 3 degree drop every hour.
2.5*60 = 150 if bust travel at 60 mile per hrs his friend live 150 miles far
2.5* 63=157.5 . if bus travel 63 miles per hours friend live 157.5 miles away
For polynomials you need to remember that they have 2 things: terms and positive exponents.
1) is not polynomial because if you rewrite it the second term has a negative exponent ( -4x^-2)
2)is a polynomial
3) is a polynomial
4) is not a polynomial because if you convert the sqrt in a exponent you have a rational exponent (4x)^1/2
5) for standard form arrange the terms from the high to low degrees
X^11 -9x^7. +4x^5. -6
The degree is 11 the leading coefficient is 1
6) same idea as 5. The degree is 6 and leading coefficient is -2
7) degree 3 and has 3 terms
8) degree 2 and has 3 terms
f(x)=<span>3x. </span>Solution: If we take ln in both side of this equation and differentiate it, we get lnf(x)=ln3x. ∴ lnf(x<span>) = xln </span>3. ∴ d dx. (lnf(x<span>)) = d dx. (xln </span>3<span>).</span>
