Answer:
Ryleigh
Step-by-step explanation:
Landon: 23.1/11 = 2.1
Blake: 33.6/14 = 2.4
Ryleigh: 21.6/8 = 2.7
Presley: 27.6/12 = 2.3
Answer:
=24x+3y
Step-by-step explanation:
6(5x+2y)−3(2x+3y)
Distribute:
=(6)(5x)+(6)(2y)+(−3)(2x)+(−3)(3y)
=30x+12y+−6x+−9y
Combine Like Terms:
=30x+12y+−6x+−9y
=(30x+−6x)+(12y+−9y)
=24x+3y
Answer:
x=3 and x=-1.25
Step-by-step explanation:
4x^2-7x=15
subtract 15 from each side:
4x^2-7x-15=0
factor (trying different numbers that the sum is 7 and the quotient is 15)
(2x-6 )(2x+2.5 )=0
2x-6=0 add 6 to each side
2x=6
x=3
2x+2.5=0 subtract 2.5 from each side
2x=-2.5
x=-1.25
The properties of a right circular cone. A cone has a radius (r) and a height (h
lol hopes this helps..
If you mean
![\dfrac{\mathrm d}{\mathrm dx}\left[4^x\ln(x)\right]](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Cleft%5B4%5Ex%5Cln%28x%29%5Cright%5D)
then first write 
. Then by the product rule,
![\dfrac{\mathrm d}{\mathrm dx}\left[4^x\ln(x)\right] = \ln(4)e^{\ln(4)x}\ln(x) + \dfrac{e^{\ln(4)x}}x = \ln(4)4^x\ln(x)+\dfrac{4^x}x=\dfrac{4^x}x\left(\ln(4)x\ln(x)+1\right)](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Cleft%5B4%5Ex%5Cln%28x%29%5Cright%5D%20%3D%20%5Cln%284%29e%5E%7B%5Cln%284%29x%7D%5Cln%28x%29%20%2B%20%5Cdfrac%7Be%5E%7B%5Cln%284%29x%7D%7Dx%20%3D%20%5Cln%284%294%5Ex%5Cln%28x%29%2B%5Cdfrac%7B4%5Ex%7Dx%3D%5Cdfrac%7B4%5Ex%7Dx%5Cleft%28%5Cln%284%29x%5Cln%28x%29%2B1%5Cright%29)
If you instead mean
![\dfrac{\mathrm d}{\mathrm dx}\left[4^{x\ln(x)}\right]](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Cleft%5B4%5E%7Bx%5Cln%28x%29%7D%5Cright%5D)
you can again rewrite 
. Then by the chain and product rules,
![\dfrac{\mathrm d}{\mathrm dx}\left[4^{x\ln(x)}\right] = e^{x\ln(x)\ln(4)}\ln(4)\left(\ln(x)+1\right) = 4^{x\ln(x)}\ln(4)(\ln(x)+1)](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Cleft%5B4%5E%7Bx%5Cln%28x%29%7D%5Cright%5D%20%3D%20e%5E%7Bx%5Cln%28x%29%5Cln%284%29%7D%5Cln%284%29%5Cleft%28%5Cln%28x%29%2B1%5Cright%29%20%3D%204%5E%7Bx%5Cln%28x%29%7D%5Cln%284%29%28%5Cln%28x%29%2B1%29)
