Answer:

- 5/3

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

= ( -1 -9)/(4 - -2)

= (-1-9)/(4+2)

= -10/6

- 5/3

Given:

The equation of circle is

$(x+3)^2+y^2=9$

To find:

The polar form of given circle.

Solution:

We have,

$(x+3)^2+y^2=9$

$x^2+2(x)(3)+(3)^2+y^2=9$ $[\because (a+b)^2=a^2+2ab+b^2]$

$(x^2+y^2)+6x+9=9$

Subtracting 9 from both sides, we get

$(x^2+y^2)+6x=0$

We know that, $x^2+y^2=r^2$ and $x=r\cos \theta$ .

$r^2+6(r\cos \theta)=0$

$r(r+6\cos \theta)=0$

$r=0$ and $r+6\cos \theta=0$

We know that, r is radius it cannot be 0. So,

$r+6\cos \theta=0$

$r=-6\cos \theta$

Therefore, the correct option is A.

A parking lot has ten parking spaces. There are the same number of cars parked in the parking lot as there are empty parking spa

Karolina [17]

Answer:

0.5

Step-by-step explanation:

Total space in the parking lot = 10

number of cars parked = p

number of empty parking spaces = e

There are the same number of cars parked in the parking lot as there are empty parking spaces.

This means,

Number of parked cars = number of empty parking spaces

p = e

If the number of parked cars and number of empty parking spaces = 10

p + e = 10

If p = 5

Then,

p + e = 10

5 + 5 = 10

Write a decimal to show the part of the parking lot that has empty parking spaces.

Empty parking space/total parking space

= 5/10

= 1/2

= 0.5

part of the parking lot that has empty parking spaces = 0.5

Answer:

(0,1) and (-2,9)

Step-by-step explanation:

A point (x,y) lies on the graph of f(x) = $(\frac{1}{3} )^{x}$ if it satisfies the condition y = $(\frac{1}{3} )^{x}$

x = 0 and y = 1.

This point satisfies the required condition as

$(\frac{1}{3} )^{0}$ = 1

Hence, this point <u>is</u> on the graph of f(x) = $(\frac{1}{3} )^{x}$

x = 3 and y = 27.

This point doesn't satisfy the required condition as

$(\frac{1}{3} )^{3}$ = $\frac{1}{27}$ ≠ 27

Hence, this point i<u>s not</u> on the graph of f(x) = $(\frac{1}{3} )^{x}$

x = -2 and y = 9.

This point satisfies the required condition as

$(\frac{1}{3} )^{-2}$ = $3^{2}$ = 9

Hence, this point <u>is</u> on the graph of f(x) = $(\frac{1}{3} )^{x}$

x = -1 and y = $-\frac{1}{3}$ .

This point satisfies the required condition as

y = $(\frac{1}{3} )^{-1}$ = $3^{1}$ = 3 ≠ $-\frac{1}{3}$

Hence, this point <u>is not</u> on the graph of f(x) = $(\frac{1}{3} )^{x}$
