A. x=3/2

D. x=1/2


Solve for x over the real numbers:

4 x^2 - 8 x + 3 = 0

The left hand side factors into a product with two terms:

(2 x - 3) (2 x - 1) = 0

Split into two equations:

2 x - 3 = 0 or 2 x - 1 = 0

Add 3 to both sides:

2 x = 3 or 2 x - 1 = 0

Divide both sides by 2:

x = 3/2 or 2 x - 1 = 0

Add 1 to both sides:

x = 3/2 or 2 x = 1

Divide both sides by 2:

Answer:  x = 3/2 or x = 1/2

Answer:

Hence, the correct options are A and D.

Step-by-step explanation:

4x^2-8x+3=0

Splitting the term (-8x) by using middle term splitting theorem:

4x^2-2x-6x+3=0

2x(2x-1)-3(2x-1)=0

(2x-1)(2x-3)=0

2x-1=0

x=\frac{1}{2}

(2x-3)=0

x=\frac{3}{2}

The solution of the given equation 4x^2-8x+3=0 :

x=\frac{1}{2},\frac{3}{2}

Hence, the correct options are A and D.

The magnitude, M, of an earthquake is defined to be M=log I/S, where I is the intensity of the earthquake (measured by the ampli
GarryVolchara [31]

Answer:

<h2>1</h2>

Step-by-step explanation:

       Magnitude M of an earthquake is defined as M=log\text{ }\frac{I}{S}. Here I is the Intensity of the earthquake and  S is the intensity of standard earthquake.

       We have an earthquake that is 10 times more intense than a standard earthquake. Let us denote the intensity of the earthquake as I.

       10 times more intense than standard earthquake ⇒ I=10S

   Magnitude of the earthquake = M\text{ = }log\text{ }\dfrac{I}{S}\text{ = }log\text{ }\dfrac{10S}{S}\text{ = }log\text{ }10\text{ = }log_{10}\text{ }10\text{ = }1

∴ Magnitude of the earthquake is 1.

Ice has a density of 0.92 g/cm3. What is the volume of 100 grams of ice? If the ice completely melted, what would the volume of
kicyunya [14]

Hello!

To find the volume of the water, we would need to use the density formula. The density formula is d = m/V.

In this formula, d is the density, m is the mass and V is the volume.

1. To find the volume of 100 grams of ice, we substitute the appropriate values into the formula and solve for the volume using basic algebra.

0.92g/cm³ = 100g/V (multiply both sides by V)

0.92g/cm³ · V = 100g (divide both sides by 0.92g/cm³)

V = 108.69 cm³.

The volume of 100 grams of ice is about 108.69 cm³.

2. To find the volume of the completely melted ice, we would use the same formula, but the density is now 1.00 g/mL.

1.00g/mL = 100g/V (multiply both sides by V)

1.00g/mL · V = 100g (divide both sides by 1.00g/mL)

V = 100 mL

Therefore, the volume of the melted ice is 100 mL.

<u>Final answers</u>:

  1. 108.69 g/cm³
  2. 100 mL

A football player punts a ball. The path of the ball can be modeled by the equation y = –0.004x2 + x + 2.5, where x is the horiz
Galina-37 [17]
The answer is <span>252.5 ft

</span><span>y = –0.004x</span>²<span> + x + 2.5
Let's take y = 0 and we'll get the quadratic equation:

</span>–0.004x² + x + 2.5 = 0
The general formula for quadratic equation is:
ax² + bx + c = 0

a = -0.004
b = 1
c = 2.5

x_{1,2} = \frac{-b+/- \sqrt{ b^{2}-4ac} }{2a} =\frac{-1+/- \sqrt{ 1^{2}-4*(-0.004)*2.5} }{2*(-0.004)} = \frac{-1+/- \sqrt{1+0.04} }{-0.008} = \\ &#10;=\frac{-1+/- \sqrt{1.04} }{-0.008} = \frac{-1+/-1.02}{-0.008}

x_1=\frac{-1+1.02}{-0.008} = \frac{0.02}{-0.008} = -2.5 \\ &#10;x_2=\frac{-1-1.02}{-0.008} = \frac{2.02}{-0.008} = 252.5

Since distance cannot be negative (x1), the correct answer is x2 = 252.5 ft
