Answer:

Discriminant(D) = 0

Therefore b² = 4ac

when b = -18, a = 1, c = c

puting the values in the equation...

(-18)² = 4(1) x C

324 = 4C

divide though by 4

we have : C = 324/4

C = 81

Answer:

43. 171 × $4.50 = $769.50

(171 ÷ 9) × 2 = 38

38 × $7.25 = $275.50

$769.50 + $275.50 = $1,045.00

$1,045.00 × 1.04 = $1,086.80

Answer: $1,086.80 for museum tickets and parking

171 + 38 = 209

209 × $6.00 = $1,254.00

$1,086.80 + $1,254.00 = $2,340.80

Answer: $2,340.80 for the total budget

44. Equation: 2a + 10 = 70

2a + 10 = 70 (subtract 10 from each side)

2a = 60 (divide each side by two)

a = 30

Answer: 30 envelopes

45. Inequality: $2.20x + $2.40 < $9.00

$2.20x + $2.40 < $9.00 (subtract $2.40)

$2.20x < $6.60 (divide by $2.20)

x < 3

Answer: x < 3

Fill in the scale dimensions in the table to the nearest thousandth. The scale of a blueprint is 1/4 inch = 1 foot. A house has
solmaris [256]
<span>Since  1' = 12'', so the scale 1/4'' to 1' is 1/4'' to 12'', or, multiplying both sides by 4, 1 to 48. </span>

<span>Convert all dimensions given from foot/inches to inches, then scale them down, dividing by 48. </span>
10ft 6in=10*12+6=126+6=132 dividing by 48. 132/48=2.75/48=0.0572*1000=57.2 inches 
<span>18' 8'' = 18 * 12 + 8 inches = 216 + 8 = 224 inches. Dividing by 48: 224/48 = 4 32/48 = 4 2/3 inch*1000=66.6

Find the distance and midpoint for (2, 0, -2) and (5, -4, 6)
sweet-ann [11.9K]
Hi, It is well simples:

The distance between two points is :

d( A, B) = √[ (xb - xa)^2+(yb - ya)^2+(zb - za)^2]


Then,

A = (xa, ya, za )

B = (xb , yb , zb)

We know:

A = ( 2 ,0 ,-2)

And,

B = (5 , -4 , 6)
___________

xb - xa = 5-2 <=> 3

yb - ya = -4 - 0 <=> -4

zb - za = 6 - (-2) <=> 8

Then us stay:

d( A, B) = √[ (3)^2 + (-4)^2+(8)^2]

= √( 9 + 16 + 64)

= √( 25 + 64)

= √(89)
