Solve the following quadratic- like equation y 1/2-4y 1/4+3=0

On solving the prοvided question, we can say that 4.75 miles were ran on day four.

A mathematical equation is a formula that jοins two statements and uses the equal symbol (=) tο indicate equality. A mathematical statement that establishes the equality of twο mathematical expressions is known as an equatiοn in algebra.

Fοr instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences οn either side of a letter is described by a mathematical formula. Often, there is only οne variable, which alsο serves as the symbol. for instance, 2x – 4 = 2.

On day one, Justin ran two miles.

He ran two miles on the second day, or 75% of it. Divide by 100 and multiply by 75 to get the percentage of two miles that is 75%.

On the secοnd day, I ran 1.5 miles, or 2 / 100, or 0.02 x 75. (I've run 3.5 miles so far)

He ran 1.5 miles further on the third day than the previous one:

1.5 + 1.5 = 3 (6.5 miles jogged sο far) (6.5 miles jogged so far)

The total number of miles run was 9.25, thus tο find the solution, we must subtract 6.5 from 9.25.

4.75 miles were ran οn day four, or 9.25 minus 6.5.

The acceleration was -26.04 m/s².

Equations of motion are a set of equations which describes the basic motion concepts like velocity, position, time and acceleration.

There are mainly three equations of motion.

v = u + at

s = ut + [tex]\frac{1}{2}[/tex] at²

v² = u² + 2as

v is the final velocity, u is the initial velocity, a is the acceleration, t is the time and s is the displacement.

Given,

Initial velocity of the motorist, u = 90 km/h = 90 × (5/18) m/s = 25 m/s

Final velocity of the motorist, v = 0 m/s (since the bike stopped)

Stopping distance, s = 12 m

Using the third equation of motion,

v² = u² + 2as

0² = 25² + (2a × 12)

24a = -625

a = -625 / 24 = -26.04 ≈ -26 m/s²

Hence the acceleration of the motorist was -26 m/s².

Answer:

x = 32

Step-by-step explanation:

First we would move the x's to the left and the numbers to the right. When doing so they switch from being positive to negative or from negative to positive.

3/4x = 27-3

Now we would try to simplify it as much as we can. Here I would make 3/4 a decimal and subtract 37-3

0.75x = 24

Now we can divide 24 by 0.75 to find x

x = 32

x = 32.

[tex]\frac{3}{4} x+3=27[/tex]

[tex]\frac{3}{4} x+3-3=27-3\\ \\\frac{3}{4} x+3-3=27-3\\ \\\frac{3}{4} x=24[/tex]

[tex]\frac{\frac{3}{4} x}{\frac{3}{4}} =\frac{24}{\frac{3}{4}}\\ \\x=24*\frac{4}{3}\\ \\x=\frac{24*4}{3} \\ \\x=\frac{96}{3} \\\\x=32[/tex]

If "32" is our correct answer, then substituting it by variable "x" on the original equation should make the equation return the same number on both sides of the equal (=) symbol. Let's test it!

[tex]\frac{3}{4} (32)+3=27\\ \\\frac{3*32}{4}+3=27\\ \\\frac{96}{4}+3=27\\ \\24+3=27\\ \\27=27[/tex]

That's correct!

Step-by-step explanation:

The transformation from the function f(x) = |x| to the function g(x) = |x| + 4 can be thought of as a vertical shift upward by 4 units. The shape of the absolute value function remains unchanged, but the entire graph is shifted upward along the y-axis by 4 units. This can be visualized by observing that for any value of x, g(x) = f(x) + 4.

So, the transformation of f(x) to g(x) is a vertical shift upward by 4 units

Answer:

Step-by-step explanation:

Step 1: Define each variable

Let's define some variables to make the calculations easier:

t1 = the median monthly rent in 1990, which is $447

t2 = the median monthly rent in 2002, which is $658

Δ = the change in median monthly rent, which is t2 - t1

Step 2: Calculate the change in median monthly rent

Δ = t2 - t1 = $658 - $447 = $211

This means that the median monthly rent increased by $211 from 1990 to 2002.

Step 3: Divide the change by the original amount

To find the percentage increase, we need to divide the change by the original amount and multiply by 100:

Δ / t1 * 100 = ($211 / $447) * 100 = 47.2%

This means that the median monthly rent increased by 47.2% from 1990 to 2002.

Step 4: Round to the nearest tenth of a percent

The final answer is 47.2%, rounded to the nearest tenth of a percent.

The percent increase in the median monthly rent prices from 1990 to 2002 was 47.2%.

The Equation x² − 15x + 12 = 0 have two Real solution and 3x² − 6x + 4 = 0 have Imaginary solution.

The discriminant, denoted by the equation b² - 4ac, can be used to ascertain if the solutions are real, repetitive, or complex:

1) If the discriminant is smaller than 0, there are two imaginary roots to the problem (s).

2) The equation has one repeating real solution if the discriminant equals zero (s).

Given:

x² − 15x + 12 = 0

Solving the Quadratic Equation

x² − 15x + 12 = 0

D = (-15)² - 4(1)(12)

D =  225 - 48

D = 177 >0

So, the Equation will have two Real solution.

b) 3x² − 6x + 4 = 0

Solving the Quadratic Equation

3x² − 6x + 4 = 0

D = b² - 4ac

Answer:

y = -1/3 x + 3

Step-by-step explanation:

To find the equation of the line that passes through the two points (-3,4) and (3,2) in slope-intercept form, we'll first find the slope of the line using the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the two given points.

Plugging in the given points, we get:

m = (2 - 4) / (3 - (-3)) = -2 / 6 = -1/3

Next, we'll use the point-slope form of a line to find the equation of the line:

y - y1 = m(x - x1)

where (x1, y1) is one of the given points, and m is the slope of the line.

We'll use the first given point, (-3,4), so we have:

y - 4 = -1/3 (x - (-3))

Expanding the right side of the equation, we get:

y - 4 = -1/3 x + 1

Finally, we'll rearrange the equation to get it in slope-intercept form, which is:

y = -1/3 x + b

where b is the y-intercept. To find b, we'll plug in one of the given points and solve for b:

y = -1/3 x + b

4 = -1/3 * (-3) + b

4 = 1 + b

b = 4 - 1

b = 3

So the equation of the line in slope-intercept form is:

y = -1/3 x + 3

Answer:

To compare the amount of money that Patrick and Brooklyn would have after 2 years, we need to calculate the interest earned using each of their methods.

For Patrick, who deposited $300 with an interest rate of 3% compounded quarterly, the formula to calculate the amount after 2 years (8 quarters) is:

A = P(1 + r/n)^(nt)

Where:

P = principal amount ($300)

r = interest rate (3%)

n = number of times compounded per year (4)

t = time in years (2)

Substituting the values into the formula:

A = $300(1 + 0.03/4)^(4 * 2)

A = $300(1.0075)^8

A = $300 * 1.06173

A = $318.52

For Brooklyn, who deposited $300 with an interest rate of 5% compounded monthly, the formula to calculate the amount after 2 years (24 months) is:

A = P(1 + r/n)^(nt)

Where:

P = principal amount ($300)

r = interest rate (5%)

n = number of times compounded per year (12)

t = time in years (2)

Substituting the values into the formula:

A = $300(1 + 0.05/12)^(12 * 2)

A = $300(1.00417)^24

A = $300 * 1.09722

A = $328.17

Therefore, after 2 years, Brooklyn would have $328.17, which is more money than Patrick's $318.52.

To find the angle that Mrs. Becker is looking down at, we can use the tangent function. We know the height of her eyes (6 feet) and the distance from her eyes to the ladybug (100 feet), so we can use the formula:

tan(angle) = height/distance

First, we'll solve for the angle:

angle = tan^-1(height/distance)

angle = tan^-1(6/100)

Using a calculator, we can find that the angle is approximately 0.0349 radians, or approximately 2 degrees.

So, Mrs. Becker is looking down at an angle of approximately 2 degrees.

Answer:

Step-by-step explanation:

The equation that represents the town's population after 4 years can be found using the formula:

P = P0 * (1 - r)^t

Where P is the population after t years, P0 is the initial population (4.11 x 10^4), r is the annual shrink rate as a decimal (9.6% as 0.096), and t is the number of years (4).

P = 4.11 x 10^4 * (1 - 0.096)^4

P = 4.11 x 10^4 * 0.6994^4

P = 4.11 x 10^4 * 0.4139

P = 1.70 x 10^4

So the town's population after 4 years is 1.70 x 10^4.

Answer:

Let P(t) be the population of the town after t years. We know that P(0) = 4.11 x 10^4. Then, the rate of change of the population is given by -0.096P(t), so we can write the differential equation:

dP/dt = -0.096P(t)

To find the population after 4 years, we need to solve this differential equation with the initial condition P(0) = 4.11 x 10^4. We can do this by separating variables and integrating both sides:

∫(dP/P) = -0.096 ∫dt

ln|P(t)| = -0.096t + C

where C is a constant of integration that can be found using the initial condition. Solving for P(t), we get:

P(t) = Ce^(-0.096t)

where C = e^(ln|P(0)|) = e^(ln|4.11 x 10^4|) = 4.11 x 10^4

Substituting in t = 4, we get:

P(4) = 4.11 x 10^4 e^(-0.096 × 4) = 4.11 x 10^4 e^(-0.384)

So, the equation representing the town's population after 4 years is:

P(t) = 4.11 x 10^4 e^(-0.096t)

In physics, displacement is defined as the change in position of an object from its initial position to its final position, measured as a straight line distance in a specific direction. It is a vector quantity, which means it has both magnitude (the distance between the starting and ending points) and direction. Displacement is different from distance, which is the actual length of the path traveled by an object regardless of its starting and ending points.

i. The person's displacement from the starting point can be calculated using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In this case, the person has walked a distance of 500 yards south and 300 yards west, which forms a right triangle. Therefore, the displacement can be calculated as the square root of (500^2 + 300^2) = 583.1 yards (rounded to the nearest hundredth).

ii. To be looking back at point A from point B, the person would have to look in the direction opposite to the direction in which they walked from A to B. Since the person first walked due south and then due west, the direction in which they would have to look to be looking back at point A is north-east. This can be calculated using trigonometry, where the tangent of the angle formed between the line connecting A and B and the due south line is equal to 300/500. Therefore, the angle formed is the arctangent of (300/500) = 31.39 degrees. However, the true bearing is measured from the north and therefore, the true bearing would be 360 - 31.39 = 328.61 degrees (rounded to the nearest hundredth).

iii. If a friend is standing at point A looking at point B, they would be looking in the direction of the line connecting points A and B. To determine the true bearing, we need to find the angle formed between the due north line and the line connecting A and B. This angle can be calculated as the arctangent of (500/300) = 59.04 degrees. However, the true bearing is measured from the north and therefore, the true bearing would be 90 + 59.04 = 149.04 degrees (rounded to the nearest hundredth).
