Answer:

  • C.

Step-by-step explanation:

<u>C. </u>

  • 5/8x + 25 = 3/8x + 15 + 1/4x
  • 5/8x + 10 = 3/8x + 2/8x
  • 5/8x + 10 = 5/8x
  • 10 = 0

Convert 0.533333... to a fraction.<br> (only the 3 is repeating)<br><br> Please show the work!!
amm1812
<span>Let x = 0.5333333333 ...

So 100x = 53.3333333333 ...
and 10x = 5.3333333333 ...
---------------------------------
90x = 53 – 5 = 48.

So x = 48/90 = 8/15 after reduction to lowest terms (by factor of 6)
0.3333... = ⅓. and that 0.5 = ½.

So 0.533333... = 0.5 + 0.0333333...0.5 + 0.3333.../10 = 1/2 + (1/3)/10 = 1/2 + 1/30 = 16/30 = 8/15</span>

Help me to solve this
antoniya [11.8K]
The answer is 2cm

8 \times 10 {}^{ - 3} \times 250 = 2000 \times 10 {}^{ - 3} \\ = 2
or:
8 \times {10}^{ - 3} \times 250 = 0.008 \times 250 \\ = 2

good luck

Divide x ^ 4 + x - 1 by x - 1
vladimir2022 [97]

The required, divide is given by =x^3+x^2+x+2+\frac{1}{x-1}

<h3>What is fraction of polynomial?</h3>

Fraction of polynomial is, in the numerator and in the denominator of a fraction there is polynomial function

=x^3+\frac{x^3+x-1}{x-1}\\

=x^3+x^2+\frac{x^2+x-1}{x-1}\\

=x^3+x^2+x+\frac{2x-1}{x-1}\\

=x^3+x^2+x+2+\frac{1}{x-1}

Thus the required, divide is =x^3+x^2+x+2+\frac{1}{x-1}.

If we graph the given points then they appear to be in the shape of cubic function so we can use standard formula of cubic function which is


y=ax^3+bx^2+cx+d


Plug the given points to get four equations


like first point (3,6) so plug x=3 and y=6 into above equation, we get:


6=a*3^3+b*3^2+c*3+d


or


6=27a+9b+3c+d


Same way by plugging other points form table, we get total four equations as follows:


6=27a+9b+3c+d, 11=125a+25b+5c+d, 11=64a+16b+4c+d, 21=343a+49b+7c+d


Now we just need to solve these equations for a, b, c and d.

Solving them to get values of a, b, c and d, we get:


a=\frac{25}{24}, b=-15, c=\frac{1715}{24}, d=-\frac{203}{2}


Now plug them into


y=ax^3+bx^2+cx+d


So the required equation will be:


y=\frac{25}{24}x^3-15x^2+\frac{1715}{24}x-\frac{203}{2}


Hence required equation in function notation can be written as


f(x)=\frac{25}{24}x^3-15x^2+\frac{1715}{24}x-\frac{203}{2}


Now to prove that above function is correct, we just graph the given points from table and the obtained function.


After graphing the given points from table and the obtained function, We see that points lie on the graph of y=\frac{25}{24}x^3-15x^2+\frac{1715}{24}x-\frac{203}{2}


Which proves that our equation is correct.
