1. If two nonvertical lines are parallel, what do we know about their slopes? If two lines are perpendicular and neither is para

yanalaym [24]

Answer:

Two straight lines with slopes m and m' are parallel when m = m'

Two straight lines with slopes m and m' are perpendicular when m × m' = - 1.

Step-by-step explanation:

Let us assume that the two non-vertical lines in the slope-intercept form are

y = mx + c ........... (1) and

y = m'x + c' ............ (2)

If those two lines are parallel then we can say the slope of them will be the same i.e. m = m'

Now, if given two straight lines (1) and (2) are perpendicular to each other and neither of them is parallel to the axes, then we can write m × m' = - 1. (Answer)

In 2000, a company had 1147 stores nationwide. By 2002, this total had grown to 1542. If the number of stores continues to gro

mr_godi [17]

12226 stores will be there in 2016

<em><u>Solution:</u></em>

<em><u>The growth function is given as:</u></em>

$y = a(1+r)^t$

Where,

y is the future value

a is the initial value

r is the growth rate

t is the number of years

From given,

In 2000, a company had 1147 stores nationwide

By 2002, this total had grown to 1542

Therefore,

y = 1542

a = 1147

t = 2000 to 2002 = 2 years

r = ?

<em><u>Substituting we get,</u></em>

$1542 = 1147(1+r)^2\\\\(1+r)^2 = \frac{1542}{1147}\\\\(1+r)^2 = 1.34437$

Taking square root of both sides

$1+ r = 1.1594\\\\r = 1.1594 - 1\\\\r = 0.1594$

<em><u>If the number of stores continues to grow exponentially at the same rate, how many stores will there be in 2016?</u></em>

Therefore,

y = ?

a = 1147

r = 0.1594

t = 2000 to 2016 = 16 years

<em><u>Substituting we get,</u></em>

$y = 1147(1 + 0.1594)^{16}\\\\y = 1147(1.1594)^{16}\\\\y = 1147 \times 10.6593\\\\y = 12226.3311 \approx 12226$

Thus 12226 stores will be there in 2016

Answer:

$16,000

Step-by-step explanation:

For easier understanding and calculation; we created a table for solving this question.

Destination → Dallas Atlanta Denver Availability

<u>↓ </u>

<u>Houston $ 8 $ 12 $ 13 850 </u>

<u />

<u>Phoenix $ 10 $ 14 $ 8 800 </u>

<u />

<u>Memphis $ 11 $ 8 $ 14 350 </u>

<u>Requirement 800 700 250 </u>

<u />

Minimum Shipping Cost to Dallas is from Houston and they have 850 air conditioners, Dallas need 800, so ship all required 800 air conditioners from Houston itself

Minimum shipping cost of Atlanta is from Memphis and they have 350 air conditioners, but Atlanta need 700, so ship all the 350 air conditioners that Memphis have to Atlanta

Minimum shipping cost to Denver is from Phoenix and they have 800 air conditioners, but Denver need 250, so ship all the required 250 air conditioners to Denver itself.

Houston $ 8 $ 12 $ 13 850

Phoenix $ 10 $ 14 $ 8 800

<u> (250) </u>

<u />

Memphis $ 11 $ 8 $ 14 350

<u> (350) </u>

<u>Requirement 800 700 250 </u>

Still Atlanta need 350 air conditioners more, the second minimum shopping cost to Atlanta is from Houston and they have 50 air conditioners left .

So, ship all the 50 air conditioners that Houston have to Atlanta

Also, sent the remaining 300 air conditioners that Atlanta need from Phoenix

Destination → Dallas Atlanta Denver Availability

<u>↓ </u>

Houston $ 8 $ 12 $ 13 850

<u> (800) (50) </u>

Phoenix $ 10 $ 14 $ 8 800

<u> (300) (250) </u>

<u />

Memphis $ 11 $ 8 $ 14 350

<u> (350) </u>

<u>Requirement 800 700 250 </u>

The total cost of shipping = ($ 8 × 800) +( ( $ 12 × 50)+($ 14 × 300) +( $ 8 × 350) ) + ( $ 8 × 250)

= ( $ 6, 400) + $ ( 600 + 4, 200 + 2, 800 ) + $ 2, 000

= $ 16,000

Therefore, the total cost = $ 16,000
