QUESTION:

If the value of the discriminant is 0, how many solutions will the quadratic have?​

ANSWER:

The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A positive discriminant indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates that the quadratic has a repeated real number solution.

Answer:

Hello!! answer: a = 45

Step-by-step explanation:

This is a complimentary angle so we will just do 90 - 45 and get 45 because 45 + 45 = 90 Hope that helps!

Answer:

a = 45

Step-by-step explanation:

The total angle of the shape is 90°

That means you should subtract 90° from 45°

90 - 45 = 45

That's your answer!

Hope this helped :)

Answer:

A= 30

Step-by-step explanation:

This requires several steps.

First, you need to find the 2 other missing angles.

One can be found easily by substracting 130 from 180

so 180-130 = 50

The other angle is the same as 8x+4

Now set up your equation

180=3x-6 + 8x+4 +50

180 = 3x + 8x -6 + 4 +50

180+6-4-50 = 11x

132 = 11x

132/11 = x

12 = x

Now plug in 12 for x in your angle A

A=3x-6

A=3 * 12 - 6

A=36 - 6

A= 30

Answer:

[tex]x = 3.072 * 10^{-5}[/tex]

Step-by-step explanation:

[tex]x = 12*0.2^8[/tex]

[tex]x = 12 * 2.56E-6 = 0.00000256[/tex]

[tex]x = 3.072E-5 = 0.00003072[/tex]

Answer:

38

Step-by-step explanation:

This looks intimidating, but if we break it into smaller parts, it actually becomes quite easy.

They separated it into different shapes for us, so now we just need to find the area of each individual shape.

The blue rectangle has lengths of 2 and 3. We multiply 2 by 3 to get the area, so the area of the blue rectangle is 6.

We do the same for the orange rectangle. Multiply 4 by 8 to get 32.

Add 32 to 6 and we get 38, the area of the entire shape.

Hope that this helps!

Answer:

-5 1/4

Step-by-step explanation:

-4 1/2 -3/4

= -4 2/4 -3/4

= -4 5/4

= -5 1/4

Answer:

-5 1/4

Step-by-step explanation:

S = 15.47 units

Step-by-step explanation:

First, convert the degree angle into radians:

68° × (π/180) = 1.19 rad = theta

The arc length S is given by

S = r × theta

= (13 units)(1.19 rad)

= 15.47 units

Answer:

15.43

Step-by-step explanation:

The formula = angle / 360 × circumference

= angle / 360 × pi diameter

= 68 / 360 × pi × 13 + 13

= 68 / 360 × pi × 26

= 17 / 19 × pi × 26

= 221 / 45 pi

= 15.43

Answer:

[tex]143.8\:\mathrm{ft^2}[/tex]

Step-by-step explanation:

The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:

Area of semi-circle (half the area of a circle): [tex]\frac{1}{2}\cdot 4.5^2\cdot \pi[/tex]

Area of trapezoid (average of bases multiplied by height): [tex]16\cdot 7[/tex]

Thus, the total area of the figure is:

[tex]\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}[/tex]
