Answer:

Quotient: x^4+7x^3-2x^2-9x-3

Remainder: -10

Step-by-step explanation:

x5 + 15x+ + 54x3 – 25x2– 75x – 34 by x + 8.

Since the exponents are arranged in descending order so, 15x^4

x^5 + 15x^4+ + 54x^3 – 25x^2– 75x – 34 by x + 8

The division is shown in figure attached.

Quotient: x^4+7x^3-2x^2-9x-3

Remainder: -10

What is the value of the numerical expression 5/8 - 5/12 (3 -1/4) + 2/3 ?

nasty-shy [4]

$\dfrac{5}{8} - \dfrac{5}{12} ( 3 - \dfrac{1}{4} )+ \dfrac{2}{3}$

$= \dfrac{5}{8} - \dfrac{5}{12} (2\dfrac{3}{4} )+ \dfrac{2}{3}$

$= \dfrac{5}{8} - \dfrac{5}{12} (\dfrac{11}{4} )+ \dfrac{2}{3}$

$= \dfrac{5}{8} - \dfrac{55}{48}+ \dfrac{2}{3}$

$= \dfrac{30}{48} - \dfrac{55}{48}+ \dfrac{32}{48}$

$= \dfrac{7}{48}$

Answer:

5. $f(x) = 10,000 (1.5)^x$

Step-by-step explanation:

==>>We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
