Answer:

p = 5

Step-by-step explanation:

We have that:

$\frac{x^{a}}{x^{b}} = x^{a-b}$

$\frac{x^{9}}{x^{4}} = x^{9-4} = x^{5}$

10/2 = 5

Then

$\frac{10x^{9}}{2x^{4}} = 5x^{9-4} = 5x^{5}$

Finding p:

$5x^{5} = px^{5}$

$p = \frac{5x^{5}}{x^{5}}$

$p = 5$

Find the equation of the line that passes through (–3, 2) and the intersection of the lines x–2y=0 and 3x+y+5=0.

ipn [44]

Answer:

$\frac{19}{7}$ x+ $\frac{11}{7}$ y+5=0

Step-by-step explanation:

the intersection of x-2y=0 and 3x+y+5 is ( $\frac{-10}{7}$ ; $\frac{-5}{7}$ )

=> the line : $\frac{19}{7}$ x+ $\frac{11}{7}$ y+5=0

How are perpendicular lines and interesting line alike? How are they different?

sleet_krkn [62]

Perpendicular lines and intersecting lines are the same because they both describe 2 lines that cross one another...

They are different because perpendicular lines cross one another in a specific way. The intersection of perpendicular lines forms 90 degree angles, while intersecting lines just describes 2 lines crossing. It could be at any angle.

The value of a boat if depreciating at at a rate of 9% per year. In 2006 the boat was worth $17,800. Find the worth of the boat

svetlana [45]

Answer:

The worth of boat in 2013 will be $9202.6

Step-by-step explanation:

Rate of depreciation = 9% = 0.09

Cost of Boat in 2006 =$ 17,800

Cost of Boat in 2013 = ?

Years = 2013-2006= 7 years

The formula used is: $\mathbf{A=P(1+r)^{t}}$

Since the value of boat is depreciating the value of r will be r=-0.09

Here P = 17,800 , r=-0.09 and t = 7 years Finding A

$A=P(1+r)^{t}\\A=17,800(1+(-0.09))^7\\A=17,800(0.91)^7\\A=17,800(0.517)\\A=9202.6$

So, the worth of boat in 2013 will be $9202.6
