Answer:

A) x=3 or x=6

Step-by-step explanation:

Factor out the GCF : 2(x^2-9x+18)

Then, set to zero.

2(x^2-9x+18)=0

2(x-3)(x-6)=0

x=3 or x=6

solong [7]

Answer: 55

Step-by-step explanation:

D=m/v

D=14.4

M=792

V= unknown

14.4=792/v- multiply both sides by V

V • 14.4=792-divide both sides by 14.4

V=55

The Pretty Pizza Company wants to open a new pizza place either on the north side of town or the south side of town. They want t

Lubov Fominskaja [6]

multiply the number of blocks by number of people per block

Then divide number of pizza places by that

1st block:

15 blocks x 220 people = 220*15 = 3300

26 pizza places = 26/3300 = 0.0078

2nd Block

175 * 22 =3850

33/3850 = 0.0085

the first one is just under 0.008 but if you round it to 3 places it is 0.008

the 2nd are is just over 0.008 ( 0.009 if you round it to 3 places)

so they would be better off building in the first area, if they build at all.

A car was valued at $39,000 in the year 1995. The value depreciated to $11,000 by the year 2003.

denis23 [38]

Answer:

14.6328% , $5836.03

Step-by-step explanation:

Here we are going to use the formula

$A_{0}(1-r)^n = A_{n}$

$A_{0}$ = 39000

r=?

$A_{8}$ = 11000

n=8

Hence

$39000(1-r)^8 = 11000$

$(1-r)^8 = \frac{11000}{39000}$

$(1-r)^8 = 0.2820$

$(1-r) = 0.2820^{\frac{1}{8}$

$(1-r) = 0.2820^{0.125}$

$(1-r) = 0.8536$

$(1-0.8536=r$

$r = 0.1463$

Hence r= 0.1463

In percentage form r = 14.63%

Now let us see calculate the value of car in 2003 that is after 12 years

we use the main formula again

$A_{0}(1-r)^n = A_{n}$

$A_{0}$ = 39000

r=0.1463

$A_{12}$ = ?

n=12

$39000(1-0.14634)^{(12} = A_{12}$

$39000(0.8536)^{12} = A_{12}$

$39000*0.1497 = A_{12}$

$A_{12}=5840.34$

Hence the car's value will be depreciated to $5840.34 (approx) by 2003.
