Answer:
A
Step-by-step explanation:
![h(t)-j(t)=t^{\frac{2}{3}}-9-[3t+5t^{\frac{2}{3}}]\\\\=t^{\frac{2}{3}}-9-3t-5t^{\frac{2}{3}}\\\\=t^{\frac{2}{3}}-5t^{\frac{2}{3}}-3t-9\\\\=[1-5]*t^{\frac{2}{3}}-3t-9\\\\=-4t^{\frac{2}{3}}-3t-9](https://tex.z-dn.net/?f=h%28t%29-j%28t%29%3Dt%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-9-%5B3t%2B5t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%5D%5C%5C%5C%5C%3Dt%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-9-3t-5t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%5C%5C%5C%5C%3Dt%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-5t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-3t-9%5C%5C%5C%5C%3D%5B1-5%5D%2At%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-3t-9%5C%5C%5C%5C%3D-4t%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D-3t-9)
Answer:
18.86
Step-by-step explanation:
8.2 x 4.6 = 37.72
37.72/2 = 18.86
Answer:
1, x/3, x^2/9, x^3/27, x^4/81
x^4 +3x^3+9x^2+27x+81
----------------------------------------
81
Step-by-step explanation:
(x/3) ^i
i=0 (x/3)^0 = 1
i=1 (x/3)^1 = x/3
i=2 (x/3)^2 = x^2/3^2 = x^2/9
i=3 (x/3)^3 = x^3/3^3 =x^3/27
i=4 (x/3)^4 = x^4/3^4 =x^4/81
The sum is
1+(x/3) + x^2/9 + x^3/27 + x^4/81
We need a common denominator of 81
1*81/81 + x/3 *27/27 + x^2/9 *9/9 + x^3/27 *3/3 + x^4/81
81+27x + 9x^2 + 3x^3 +x^4
----------------------------------------
81
Rewriting from largest power to smallest power
x^4 +3x^3+9x^2+27x+81
----------------------------------------
81
