Answer:

x = - 2, x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

2x² + x - 6 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 6 = - 12 and sum = + 1

The factors are + 4 and - 3

Use these factors to split the x- term

2x² + 4x - 3x - 6 = 0 ( factor the firs/second and third/fourth terms )

2x(x + 2) - 3(x + 2) = 0 ← factor out (x + 2) from each term

(x + 2)(2x - 3) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Answer:

The value of the gift card = v = $40

The visit to the skate cost = $8

The number of visits = n

∴ n = the value of the gift card over the cost of one visit to the skate

∴ n = v/8 = 40/8 = 5

Step-by-step explanation:

The general function for relating the value of the gift card, v, in terms if the number of visits, n. ⇒⇒⇒   v = 8n

Answer:

P (Success) = 1/8

P (Failure) = 7/8

Step-by-step explanation:

It is provided that a spinner is divided into 8 equals sections and the sections are labeled 1 through 8.

Only one section is considered as success and the remaining seven are failures.

So, the probability of a success is,

P (Success) = 1/8

And the probability of a failure is,

P (Failure) = 7/8

Answer: -24

Step-by-step explanation: Convert the decimal into a fraction. Use -a/b=a/-b=-a/-b, to rewrite the fraction. Simplfy the complex fraction. Multiply both sides of the equation by 6. Move constant to the right-hand side and change its sign. Add the numbers Divide both side of the equation by -5 and you get -24.

Answer:

carolina needs to buy at least 713 paintballs to get $10 off

Step-by-step explanation:

Entrance fee = $18

Fee per ball = $0.08

The field has a promotion that says, "Get $10 off if you spend $75 or more"

Let B represent the number of paintballs that Carolina buys.

18 + 0.08B ≥ 75

Subtract 18 from both sides

0.08B ≥ 75 - 18

0.08B ≥ 57

Divide both sides by 0.08

B ≥ 57 / 0.08

B ≥ 712.5

Approximately

B ≥ 713

carolina needs to buy at least 713 paintballs to get $10 off

Answer:

[tex] x = 13.8 ft [/tex]

Step-by-step explanation:

Since it's a right triangle, apply pythagorean theorem.

The formula is given as a² + b² = c²

Where,

a = 3.7 ft

c = 14.3 ft

b = x

Plug in the values into the formula:

[tex] 3.7^2 + x^2 = 14.3^2 [/tex]

[tex] 13.69 + x^2 = 204.49 [/tex]

Subtract 13.68 from both sides

[tex] x^2 = 204.49 - 13.69 [/tex]

[tex] x^2 = 190.8 [/tex]

[tex] \sqrt{x^2} = \sqrt{190.8} [/tex]

[tex] x = 13.8 [/tex] (nearest tenth)

(3rd choice)

Answer: I say B

Step-by-step explanation:

Answer:

A. t=-2h+32

Step-by-step explanation:

I'm pretty sure it's A. If the temperature starts at 32 degrees at midnight, that is going to be it's own number, not joined with a variable. In contrast, the temperature drops 2 degrees every hour, so the variable h will have a 2 with it (2h). But because it drops, the 2h will actually be negative. The equation would be written like this...

t=-2h+32, which is answer A.

Answer:

a) 30feet

b) 9.12feet

Step-by-step explanation:

a) Given the path of the ball is modeled by the equation y=-0.02(x-18)²+12​, where;

x is the​ ball's horizontal distance in feet from​ Amaya's position

y is the distance in feet from the ground to the ball.

The ball will be at the maximum height when dy/dx = 0

Differentiate the function:

dy/dx = 2(-0.02)(x-18)^(2-1)+0

dy/dx = -0.04(x-18)

Equate the resulting expression to zero and find x as shown;

-0.04(x-18) = 0

Open the parentheses

-0.04x+0.04(18) = 0

-0.04x+0.72 =0

-0.04x = -0.72

x = -0.72/-0.04

x = 18ft

Hence the ball is 18ft away from Amaya when it is at its maximum height

b) To get the balls height y when x = 30, we will substitute x = 30 into the equation given and calculate the value of y as shown:

y=-0.02(x-18)²+12

y = -0.02(30-18)²+12

y= -0.02(12)²+12

y = -0.02(144)+12

y = -2.88+12

y = 9.12 feet

Hence the Ball's height is 9.12feet when it crosses the net at x = 30.
