Find the slope of the line segment shown
A . -1/2
B.-1
C.1/2
D.1

Given:

The equation is:

[tex](2x+1)(x-2)=0[/tex]

To find:

The values of a, b and b from the standard form.

Solution:

The standard form of a quadratic equation is:

[tex]ax^2+bx+c=0[/tex]            ....(i)

We have,

[tex](2x+1)(x-2)=0[/tex]

In can be rewritten as

[tex]2x(x)+(2x)(-2)+(1)(x)+(1)(-2)=0[/tex]

[tex]2x^2-4x+x-2=0[/tex]

[tex]2x^2-3x-2=0[/tex]             ...(ii)

On comparing (i) and (ii), we get

[tex]a=2,b=-3,c=-2[/tex]

Therefore, the correct option is C.

Answer:

a displacement of 3 meters.

Step-by-step explanation:

you move 6 meters to the right, then 3 meters to the left

6 - 3 = 3

displacement is the distance away from the starting point

The ball traveled a total displacement of 3m.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

      <------------6m----------------->

Ball ____________________

                       Ball_________

                             <------3m------>

Distance traveled by the ball.

= 6 m + 3m

= 9 m

Displacement is the shortest distance traveled by the ball.

= 6 - 3

= 3m

Thus,

Displacement is 3m.

Answer:

63.5°

Step-by-step explanation:

Reference angle = x°

Opposite = 17

Hypotenuse = 19

Apply the trigonometric function, SOH:

[tex] sin(x) = \frac{Opp}{Hyp} [/tex]

Substitute

[tex] sin(x) = \frac{17}{19} [/tex]

[tex] x = sin^{-1}(\frac{17}{19}) [/tex]

Answer:

dale is not correct

the correct angle is 30 degrees

Step-by-step explanation:

A cake is shaped like a circle

the total sum of angles in a circle is 360 degrees

If Dale and 2 friends share one fourth of a cake, the total angles they share = (1/4) X 360 = 90 degrees

If the 3 friends share the cake equally, the angles each get = (1/3) x 90 = 30 degrees

the correct angle is 30 degrees and not 45 degrees. Thus, Dale is wrong

Answer:

50.24 feet²

Step-by-step explanation:

Given that:

Diameter of circular rug = 8 feets

To obtain the area of the circular rug, we use the formula for the Area of a circle = πr²

A = πr²

r = Radius of circle = diameter / 2 = 8 /2 = 4 feets

Area of circular rug = π * 4²

Area of circular rug = 3.14 * 16 = 50.24 feet²

Step-by-step explanation:

Giving the following information:

A store is running a sale where all of the items are 35% off the normal price. The price of a video game you want to buy is normally $61.97.

To calculate the discounted selling price, we need to use the following formula:

Discounted price= selling price*(1 - discount rate)

Discounted price= 61.97*(1 - 0.35)

Discounted price= $40.28
