Simplify this problem

ikadub [295]

Answer:

$\boxed{ \frac{ \sqrt[3]{ {x}^{11} } }{4} }$

Step-by-step explanation:

$= > \frac{ {x}^{4} }{ \sqrt[3]{64x} } \\ \\ = > \frac{ {x}^{4} }{ {(64x)}^{ \frac{1}{3} } } \\ \\ = > \frac{ {x}^{4} }{ ({64}^{ \frac{1}{3} } )\times ({x}^{ \frac{1}{3} } )} \\ \\ = > \frac{ {x}^{4} }{ ({( {4}^{3} )}^{ \frac{1}{3} }) \times( {x}^{ \frac{1}{3} } )} \\ \\ = > \frac{ {x}^{4} }{ ({4}^{ \cancel{3} \times \frac{1}{ \cancel{3}} } ) \times( {x}^{ \frac{1}{3} } )} \\ \\ = > \frac{ {x}^{4} }{4 {x}^{ \frac{1}{3} } } \\ \\ = > \frac{ {x}^{4 - \frac{1}{3} } }{4} \\ \\ = > \frac{ {x}^{ \frac{12 - 1}{3} } }{4} \\ \\ = > \frac{ {x}^{ \frac{11}{3} } }{4} \\ \\ = > \frac{ \sqrt[3]{ {x}^{11} } }{4}$

Find the discriminant of 3x^2-10+-2

Dahasolnce [82]

Step-by-step explanation:

y = 3x² - 10x - 2

a = 3

b = -10

c = -2

D = b² - 4ac

D = (-10)² - 4.3.(-2)

D = 100 + 24

D = 124

Kate packs snow into 5 identical jars. Each jar represents a different depth of snow. Kate then lets the snow in each jar comple

Xelga [282]

Answer:

A, C, E

Step-by-step explanation:

From the table you can see that the water depth cahnges

$0.8-0.4=1.2-0.8=1.6-1.2=2.0-1.6=0.4\ in$

for every

$4-2=6-4=8-6=10-8=2\ in$ of snow (option B is false).

This means that the function modelling this situation is linear function (option A is true and option D is false). Let the equation of this function be $y=ax+b.$ Then

$0.4=2a+b,\\ \\0.8=4a+b.$

Subtract these two equations:

$2a=0.8-0.4,\\ \\2a=0.4,\\ \\a=0.2.$

Hence,

$b=0.4-2\cdot 0.2=0.$

The equation of the straight line (the graph of linear function) is $y=0.2x.$ (option E is true) This line passes through the point (0,0), because its coordinates satisfy the equation (option C is true).
