When the discriminant b² - 4ac is greater than zero and also a perfect square, the nature of roots of the quadratic equation ax² + bx + c = 0 will be real and distinct.
A perfect square means that the discriminant can be written as a product of two equal factors, for example (x+y)^2 = x^2 + 2xy + y^2. In this case the roots can be easily calculated by using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
In this scenario, the square root of the discriminant will be a real number and not a complex number, and the equation will have two distinct solutions for x. This means that the graph of the equation will cross the x-axis twice.
It's important to notice that the values of a,b and c also play an important role in the nature of the roots.

Sydney is deciding between two parking garages. Garage A charges an initial fee of
$12 to park plus $4 per hour. Garage B charges an initial fee of $7 to park plus $5 per
hour. Let A represent the amount Garage A would charge if Sydney parks for t hours,
and let B represent the amount Garage B would charge if Sydney parks for t hours.
Write an equation for each situation, in terms of t, and determine the hours parked,
t, that would make the cost of each garage the same.
The equation for Garage A can be expressed as A = 12 + 4t, and the equation for Garage B as B = 7 + 5t.
Write an equation for each situation?In order to determine the hours parked, t, that would make the cost of each garage the same, we first set the two equations equal to each other, A = B.Then, we can solve for t by subtracting 7 from both sides of the equation and dividing by -1.This gives us t = -5. Since we cannot park for a negative number of hours, this tells us that the cost of each garage will never be the same.The equation for Garage A is A = 12 + 4t, while the equation for Garage B is B = 7 + 5t. To find the number of hours, t, that would make the cost of each garage the same, we must set A = B and solve for t.Therefore, 12 + 4t = 7 + 5t, and subtracting 7 from both sides of the equation yields 5t = 5, and t = 1. Thus, if Sydney parks for 1 hour, the cost of both Garage A and Garage B would be the same.A = 12 + 4t
B = 7 + 5t
12 + 4t = 7 + 5t
4t - 5t = 7 - 12
-t = -5
t = 5 hours

What are the 3 steps to graph a line when given an equation?.
There are three important steps to graph a line when an equation is given to us.
Step 1: Determine the x-intercept and y-intercept on the line.Step 2: Plot the x-intercept and y-intercept points on a graph. Step 3: Draw a line through the 2 points.Let us look at an example for the same.
Let us graph the equation 6x + 2y = 12
Finding the x-intercept (the x-intercept has a y-value of 0),
6x + 0 = 12
⇒ x = 2
Hence, x-intercept is (2,0)
Finding the y-intercept (the y-intercept has an x-value of 0),
0 + 2y = 12
⇒ y = 6
Hence, y-intercept = (0,6).
The graph is shown in the diagram after plotting the 2 intercepts on a graph and a line drawn through them.

B. x > 49 inches
C. 40 < x < 50 inches
D. 70% of 5 year olds are below what height?
A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.
Explain about the normal distribution?An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the center of the range.
A data set must (when graphed) follow a bell-shaped, symmetrical curve that is centered around the mean in order to be regarded as having a normal distribution. Additionally, it must follow the empirical rule that shows the proportion of the data set that lies within (plus or minus) 1, 2, and 3 standard deviations of the mean.
Using the inverse standard normal calculator, we can determine the height at which 70% of 5-year-olds are below it, yielding a z-score of 0.84162. Using the formula x = mean + (z-score * standard deviation), this z-score can be used to determine the corresponding x value, which in this case would be
36 + (0.84162*10) = 42.4 inches.

what is x? please help
Answer:
x = 132
Step-by-step explanation:
The sum of interior angles in parallelogram equals 360. Opposite angles are congruent. (have equal measures)
360 = 48 x 2 + 2x
360 = 96 + 2x
(subtract 96 from both sides)
264 = 2x
(divide both sides by 2)
132 = x
Check:
2x + (48 x 2) = 360
(132 x 2) + 96 = 360
264 + 96 = 360
360 = 360
Answer: 132 Degrees
Step-by-step explanation: Since you know all the angles have to add up to 360 and one of the angles is 48. Alternate angles are always equal so you would do 48 and double that making 96. 360-96 leaves you with 264. Using the same alternate angles rule you would just divide that by 2 which leaves you with 132 degrees.

You are paid 1. 5 times your normal hourly rate for each hour you work over 40 hours in a week. You worked 46 hours this week and earned $612. 50.
Your normal hourly rate is $40.50 and you earned $612.50 for working 46 hours this week, which is 1.5 times your normal hourly rate for each hour over 40.
Your normal hourly rate is the amount of money you get paid per hour for working. The overtime rate is For every hour you work over 40 in a week, your hourly wage will increase by 1.5.This means that if you work 46 hours in a week and your normal hourly rate is $40.50, you would receive $40.50 for each hour up to 40 hours, and then an additional $60.75 for each hour after that. This means that you would have earned a total of $612.50 for working 46 hours this week, with $405 for 40 hours and $207.50 for the 6 hours of overtime.
Normal hourly rate (40 hours) = 40 hours x $40.50/hour = $1,620
Overtime rate (6 hours) = 6 hours x $60.75/hour = $364.50
Total earned = $1,620 + $364.50 = $1,984.50

An instrument maker creates a triangle in the shape of an isosceles triangle by bending a metal rod. The rod is 13 inches long, and the bottom of the triangle is longer than the two sides. What is the length of the longest side?.
The length of the longest side of the isosceles triangle is 5 inches.
An isosceles triangle is a type of triangle in which two sides have the same length. The two equal sides are called the legs, and the third side, which is the base, is called the hypotenuse. The angle between the legs is called the vertex angle.
An isosceles triangle can be acute, meaning that the vertex angle is less than 90 degrees, right, meaning that the vertex angle is exactly 90 degrees, or obtuse, meaning that the vertex angle is greater than 90 degrees.
It's important to note that all equilateral triangles are isosceles but not all isosceles triangles are equilateral.
Given,
The length of the rod is 13 inches.
The length of the sides are x, x-1 and x-1.
We know that,
The rod length is 13 inches the mean perimeter is 13 inches.
So,
x + x-1 + x-1 = 13
=> 3x- 2 = 13
=> 3x= 15
=> x= 5 inches
Therefore, the other two sides = x-1 = 5-1 = 4 inches

A recipe for crumb cake says to mix 3/8 cup of brown sugar and 1/3 cup of white sugar.
From this sugar mixture, set aside 1/4 cup for the crumb topping.
The remaining sugar mixture is used to make the cake.
What amount of the sugar mixture is used to make the cake?
A.) 17/24
B.) 11/24
C.) 1/2
D.) 7/12
Answer:
C) 1/2
Step-by-step explanation:
We know that 3/8 cup of brown sugar and 1/3 cup of white sugar are mixed together to make the sugar mixture.
From this sugar mixture, 1/4 cup is set aside for the crumb topping.
To find out how much sugar mixture is used to make the cake, we need to subtract the amount set aside for the crumb topping from the total sugar mixture.
We can start by converting the mixed unit of measurement (brown sugar in cups and white sugar in cups) to a single unit of measurement (cups)
3/8 cup of brown sugar + 1/3 cup of white sugar = (3/8)+(1/3) = 5/12 cup + 4/12 cup = 9/12 cup.
1/4 cup is set aside for the crumb topping.
So, the remaining sugar mixture used to make the cake is 9/12 cup - 1/4 cup = (9/12) - (1/4) = (9-3)/12 = 6/12 cup = 0.5 cup

Which ordered pair is in the solution set of 12 2 2x+4y?
For the linear equation 12 = 2x+4y, the value of ordered pairs are (0,3) and (6,0).
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The given linear equation is 12 = 2x + 4y
Substitute the value of x as 0 to find the value of y -
12 = 2x + 4y
12 = 2(0) + 4y
12 = 4y
y = 12/4
y = 3
Therefore, the value for y is obtained as 3.
Substitute the value of y as 0 to find the value of x -
12 = 2x + 4y
12 = 2x + 4(0)
12 = 2x
x = 12/2
x = 6
Therefore, the value for x is obtained as 6.
An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence. In order to understand a point visually, it can be helpful to position it on the Cartesian plane. An ordered pair's numerical values may be fractions or integers.

The x-coordinates will be equidistant to the reflection line, just on opposite coordinates.
Considering that the reflection changes the "faces" of the triangles, D and E are equivalent vertices, thus the reflection line is given by the mean of the x-coordinates of these two points, hence:
x = (-3 + 1)/2
x = -1.

Burj Khalifa i the tallet building in the world. It height i approximately 89,800 cm. The contruction team i planning to intall a 60 m long lightning rod on top of it. What will be the total height of the tructure , in metre , after the intallation of the rod
The total height of the structure after the installation of the rod will be 898.60 metres.
60 metres (rod) + 828 metres (Burj Khalifa height) = 888 metres
888 metres + 10 metres (approximate height of the lightning rod) = 898.60 metres
The Burj Khalifa is the world's tallest building with a height of 828 metres. It is located in Dubai, United Arab Emirates. The construction team is planning to install a 60 metre long lightning rod on top of the Burj Khalifa. This will increase the total height of the structure to 898.60 metres. The lightning rod is necessary for protecting the structure from lightning strikes which can cause significant damage. This will make the Burj Khalifa even taller, and will ensure the safety of the building as well as the people living in and around it.

By using the unitary method
The unitary approach is a methodology for problem-solving that involves first determining the value of a single unit and then determining the necessary value by multiplying the single unit value.
The unitary method's formula is to get the value of a single unit and then multiply that value by the number of units to obtain the required value.
Consequently, 8+4=12
Kelli has already placed 12 calls.

What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
From the given figure,
Using Pythagoras theorem to ΔBDC
Now, BC²=8²+4²
BC=√80
In ΔABD,
AB²=BD²+AD²
AB²=8²+x² ------(I)
In ΔABC
AC²=AB²+BC²
(x+4)²=AB²+80
AB²=(x+4)²-80 ------(II)
From equation (I) and (II), we have
64+x²=x²+8x+16-80
8x=128
