Mathematics
1 answer:
TEA [102]3 years ago
5 0

hello,

here is your answer:

**********

2x³ - 3x² - 17x + 30

(2x³ - 3x²) (- 17x + 30)   <em>[group the terms]</em>

(2×x×x×x - 3×x×x) (1×-17×x + 1×30)   <em>[find common factors]</em>

x² (2x - 3) 1 (-17x + 30)   <em>[separate the common factors]</em>

<em />

ans: x² (2x - 3) 1 (-17x + 30)

You can verify the answer by multiplying it, you should be able to get the expression we started with (2x³ - 3x² - 17x + 30).

**********

hope this helped,

:)

Step-by-step explanation:

<u>Given function:</u>

  • f(x) = \frac{1}{x\sqrt{x} }

<u>Equivalent expression is:</u>

  • \frac{1}{x\sqrt{x} } = x^{-1}x^{-1/2} = x^{-1 - 1/2} = x^{-3/2}

A trough is 8 feet long and has perpendicular cross section in the shape of an isosceles triangle (point down) with base 1 foot
murzikaleks [220]

Answer:

Dh/dt  = 0.082 ft/min

Step-by-step explanation:

As a perpendicular cross section of the trough is in the shape of an isosceles triangle the trough has a circular cone shape wit base of  1 feet and height     h = 2 feet.

The volume of a circular cone is:

V(c)  = 1/3 * π*r²*h

Then differentiating on both sides of the equation we get:

DV(c)/dt   = 1/3* π*r² * Dh/dt   (1)

We know that DV(c) / dt   is  1 ft³ / 5 min      or     1/5  ft³/min

and  we are were asked how fast is the water rising when the water is 1/2 foot deep. We need to know what is the value of r at that moment

By proportion we know

r/h  ( at the top of the cone  0,5/ 2)   is equal to  r/0.5  when water is 1/2 foot deep

Then      r/h   =   0,5/2   =  r/0.5

r  =  (0,5)*( 0.5) / 2        ⇒   r  =  0,125 ft

Then in equation (1) we got

(1/5) / 1/3* π*r² =  Dh/dt

Dh/dt  = 1/ 5*0.01635

Dh/dt  = 0.082 ft/min
