Step-by-step explanation:

substitute x to 150

=0.00125(x)^4+x-3

=0.00125(150)^4+150-3

WE ARE USING PEDMAS HERE SO BE CARE-FULL <u>parenthesis,exponent,multiplication,division,addition,subtraction</u>

<u>=0.00125(506250000)+150-3</u>

<u>=632812.50+150-3</u>

=<u>632962.50-3</u>

Answer:

\frac{7\sqrt{5} }{8}

Step-by-step explanation:

Using the rules of radicals

\sqrt{\frac{a}{b} } = \frac{\sqrt{a} }{\sqrt{b} }

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Given

\sqrt{\frac{245}{64} } = \frac{\sqrt{245} }{\sqrt{64} }

Simplifying the radicals

\sqrt{245}

= \sqrt{5(7)(7)}

= \sqrt{49(5)}

= \sqrt{49} × \sqrt{5} = 7\sqrt{5}

and

\sqrt{64} = 8

The simplified radical is

\frac{7\sqrt{5} }{8}

4/7(21/8 x + 1/2) = -2(1/7 - 5/28x)<br> What is x in decimal form?
frez [133]

Answer:

x=1.22930

Step-by-step explanation:

47(218 x+12 ) =−2(17 −528 x)

Simplify 47(218 x+12 ) :    327(21x+4) 327(21x+4) =−2(17 −528 x)

Multiply both sides by 7(21x+4)

327(21x+4) · 7(21x+4)=−2(17 −528 x)· 7(21x+4)

Simplify, 32=−14(17 −528 x)(21x+4)

Solve  32=−14(17 −528 x)(21x+4):    x=32+4√589105 , x=32−4√589105 x=32+4√589105 , x=32−4√589105
