Lynna [10]2 years ago
3 0

Step-by-step explanation:

Formula for midpoint is ;

m.p = ( x1 + x2/2 , y1 + y2/2)

So x1= 2 and y1 = -9 and the midpoint has already been given so just equate .

( -2 , -1 ) = ( 2 + x2/2 , -9 + y2 /2)

so now equate -2 to 2+x2/2 and -1 to -9 + y2/2

-2 = 2 + x2/ 2. -1 = -9 + y2 / 2

2 + x2 = -4. -9 + y2 = -2

x2 = -4 -2. y2 = -2 + 9

x2 = -6. y2 = 7

Answer:

( -6 , 7 )

In the 1990s the demand for personal computers in the home went up with household income. For a given community in the 1990s, th
WITCHER [35]

Answer:

a) 0.5198 computers per household

b) 0.01153 computers

Step-by-step explanation:

Given:

number of computers in a home,

q = 0.3458 ln x - 3.045 ;   10,000 ≤ x ≤ 125,000

here x is mean household income

mean income = $30,000

increasing rate, \frac{dx}{dt} = $1,000

Now,

a) computers per household are

since,

mean income of  $30,000 lies in the range of 10,000 ≤ x ≤ 125,000

thus,

q = 0.3458 ln(30,000) - 3.045

or

q = 0.5198 computers per household

b) Rate of increase in computers i.e \frac{dq}{dt}

\frac{dq}{dt} = \frac{d(0.3458 ln x - 3.045)}{dt}

or

\frac{dq}{dt}=0.3458\times(\frac{1}{x})\frac{dx}{dt} - 0

on substituting the values, we get

\frac{dq}{dt}=0.3458\times(\frac{1}{30,000})\times1,000

or

= 0.01153 computers

B.

  • 12 - 16 = -4, true

C.

<u>Mean:</u>

  • Homework = (4 + 6*2+10*3+12*2+14*4+16*2+18)/15 = 11.73
  • Television = (0 + 10*3+12*1+16*3+18*4+20*3)/15 = 14.8

<u>The difference:</u>

  • 14.8 - 11.73 > 1, NOT true
