Answer:

see below

Step-by-step explanation:

all formulas of exponent given by:

\displaystyle {x}^{1}  = x  \stackrel{ \rm example}{ \iff} 2^{1}  = 2

\displaystyle{x}^{0}  = 1\stackrel{ \rm example}{ \iff} 2^{0}  = 1

\rm \displaystyle {x}^{m} \cdot  { x }^{n}   =  {x}^{m + n}  \stackrel{ \rm example}{ \iff} x^{1 } \cdot  {x}^{2}   = x^{1 + 2 } =  {x}^{3}

\displaystyle \sqrt[n]{{x} }= x^{1/n} \stackrel{ \rm example}{ \iff} \sqrt[3]{x}  = x^{1/3}

\rm \displaystyle  \frac{{x}^{m}  }{ { x }^{n}}   =  {x}^{m  - n}  \stackrel{ \rm example}{ \iff}  \frac{x^{3} }{ {x}^{1}  } = x^{3  -  1} =  {x}^{2}

\rm \displaystyle ({x}^{m} {)}^{n} =  {x}^{m n}  \stackrel{ \rm example}{ \iff} (x^{1 } {)}^{2}  = x^{ 2 }

\rm \displaystyle ({x}^{m} {y}^{m}  {)}^{n} =  {x}^{m n}  {y}^{mn}  \stackrel{ \rm example}{ \iff} (x^{1 } { {y}^{1} )}^{2}  = x^{ 2 }  {y}^{2}

\rm \displaystyle   \left(\frac{{x}^{}  }{ { y }^{}}  \right) ^{m}   =  \frac{{x}^{m}  }{ { y }^{n} } ^{}    \stackrel{ \rm example}{ \iff}   =   \left(\frac{ {x}^{2} }{ {y}^{2} }  \right)^{2}  = \frac{ {x}^{4} }{ {y}^{4} }

\displaystyle {x}^{ - n}  =  \frac{1}{ {x}^{n} }  \stackrel{ \rm example}{ \iff} x^{ - 2}  =  \frac{1}{ {x}^{2} }

A hiker starting at point P on a straight road wants to reach a forest cabin that is 2 km from a point Q, 3 km down the road fro
pantera1 [17]

Answer:

2.19 km

Step-by-step explanation:

If x is the distance she walks down the road before turning, then the total time is:

t = x/8 + √((3 − x)² + 2²) / 3

t = x/8 + √(9 − 6x + x² + 4) / 3

24t = 3x + 8√(13 − 6x + x²)

24t = 3x + 8(13 − 6x + x²)^½

Take derivative of both sides with respect to x.

24 dt/dx = 3 + 4(13 − 6x + x²)^-½ (-6 + 2x)

When t is a minimum, dt/dx = 0.

0 = 3 + 4(13 − 6x + x²)^-½ (-6 + 2x)

-3 = 4(13 − 6x + x²)^-½ (-6 + 2x)

3 / (6 − 2x) = 4(13 − 6x + x²)^-½

3 / (24 − 8x) = (13 − 6x + x²)^-½

(24 − 8x) / 3 = (13 − 6x + x²)^½

(24 − 8x)² / 9 = 13 − 6x + x²

576 − 384x + 64x² = 117 − 54x + 9x²

459 − 330x + 55x² = 0

Solve with quadratic formula.

x = [ 330 ± √((-330)² − 4(55)(459)) ] / 2(55)

x = (330 ± √7920) / 110

x = 2.19 or 3.81

Since 0 < x < 3, x = 2.19.

Solve the equation for y.<br><br> 4.2x−1.4y=2.1
Vlada [557]

Answer:

y=3x- 3/2

Step-by-step explanation:

4.2x−1.4y=2.1

Subtract 4.2x from each side

4.2x-4.2x−1.4y=-4.2x+2.1

-1.4y = -4.2x +2.1

divide each side by -1.4

-1.4y/-1.4y = -4.2x/ -1.4 +2.1/-1.4y

y=3x- 3/2
