solve for x: by completing the square:

(3 x^2 - 4 x + 2)/(3 x - 19) = 0

Multiply both sides by 3 x - 19:

3 x^2 - 4 x + 2 = 0

Divide both sides by 3:

x^2 - (4 x)/3 + 2/3 = 0

Subtract 2/3 from both sides:

x^2 - (4 x)/3 = -2/3

Add 4/9 to both sides:

x^2 - (4 x)/3 + 4/9 = -2/9

Write the left hand side as a square:

(x - 2/3)^2 = -2/9

Take the square root of both sides:

x - 2/3 = (i sqrt(2))/3 or x - 2/3 = -(i sqrt(2))/3

Add 2/3 to both sides:

x = 2/3 + (i sqrt(2))/3 or x - 2/3 = -(i sqrt(2))/3

Add 2/3 to both sides:

Answer: x = 2/3 + (i sqrt(2))/3 or x = 2/3 - (i sqrt(2))/3

ASK YOUR TEACHER Two streets meet at an 84° angle. At the corner, a park is being built in the shape of a triangle. Find the are
Alla [95]

Answer:

22,203 ft^2

Step-by-step explanation:

The area of a triangle with angle ∅ and two sides a and b is;

Area A = 1/2 × absin∅ ......1

The park is in the shape of a triangle, with two sides and an angle given;

Given;

a = 190 ft

b = 235 ft

∅ = 84°

Substituting the values into equation 1;

Area of the park;

A = 1/2 × 190 × 235 × sin84°

A = 22,202.70131409 ft^2

A = 22,203 ft^2 (to the nearest whole number)

Area of the park is 22,203 ft^2

Peter randomly draws a card from a deck of 24. The odds in favor of his drawing a spade from the cards are 1:3. What is the prob
oee [108]

Answer:

1 /4

Step-by-step explanation:

Given that :

Let :

P(S) = probability of drawing a spade

Odds in favor of drawing a spade = 1:3 ; this could be interpreted as :

P(drawing a spade)/P(not drawing a spade) = 1:3

P(S) / P(S') = 1/ 3

P(S') = 1 - P(S)

P(S) / (1 - P(S)) = 1 / 3

Cross multiply :

3P(S) = 1 - P(S)

Collect like terms

3P(S) + P(S) = 1

4P(S) = 1

P(S) = 1/4

Hence, probability ratio of drawing a spade P(S) = 1/4
