Solve each equation with the quadratic formula.
6) 4v2 + 6v - 88 = 0

Answers

Step-by-step explanation:

The quadratic equation given to us is ,

→ 4v² + 6v - 88 = 0 .

So , wrt to standard form of a quadratic equation ax² + bx + c = 0 , the Zeroes are given by using the Quadratic formula as ,

⇒ x = -b ± √ ( b² - 4ac) / 2a

⇒ x = -6 ± √ [6² - 4 × 4 × (-88) ] / 2×4

⇒ x = -6 ± √ [ 36 + 1408 ] / 8

⇒ x = -6 ± √ 1444 / 8

⇒ x = -6 ± 38 / 8

⇒ x = -6 +38/ 8 , -6 -38 / 8

⇒ x = 32/8 , -44/8

⇒ x = 4 , -11/2

Here I took v as x . So we can replace it .

Hence the value of v is 4 , -11/2 .

Answer: x=12dm

Step-by-step explanation:

c=13 means hypotenous

a=5 means altitude

b=x=? means base

By pythagorean theorem

c^2=a^2+b^2

(13)^2=(5)^2+(x)^2

169=25+x^2

x^2=169-25

x^2=144

Taking sqrt on both sides

x=12

PLEASE HELP ILL MARK BRAINLIST The drama club is going on a trip to Brenau University's theatre. The trip costs each member $65. Included in that price is $10 for the cost of renting a charter bus and the cost of 2 plays. Each play costs the same price.

Write an equation representing the cost of the trip for each member. Let x represent the cost of each play.

Determine the price of one play. Solve your equation by showing your work and steps. (10 points)

Answers

9514 404 393

Answer:

65 = 10 + 2x . . . equation for trip costx = 27.50 . . . cost of play

Step-by-step explanation:

We are told that the costs add up this way:

trip cost = bus rental + 2 × (cost of play)

Given that ...

trip cost = $65bus rental = $10cost of play = x

The above equation can be rewritten as ...

65 = 10 + 2x . . . . . . the desired equation

Solving for x, we have ...

55 = 2x . . . . subtract 10

27.50 = x . . . . divide by 2

The cost of one play is $27.50.

Equation of circle in center radius form is given as:

[tex] (x - h) ^2 +(y-k) ^2 =r^2 [/tex]

The Wiggins Family ate dinner at a restaurant. The total cost of the meal was $85.60. The family left a 15% tip for the waiter. How much money was the total bill? (Make sure you type your answer using $ and the decimal)

Fast please

Answers

Answer:

$98.44

Step-by-step explanation:

You already know how much the actual dinner was so all you have to do is figure out how much 15% of the $85.60 is which is $12.84 meaning that they left a tip of $12.84 for the waiter. Then you would just add the cost of the dinner with the tip to get the total amount they spent. $85.60 + $12.84 = $98.44. So the total amount the Wiggins spent is $98.44
