In order to find the y− intercept of a parabola in factored form, plug in 0 for x and find the corresponding y− value
What is coordinates of a vertex in factored form?The simplest way to obtain a vertex in factored form is to locate the axis of symmetry, substitute that as x, and then solve for y. With the formula x=r+s2, which means that r and s are the zeros, it is possible to determine the axis of symmetry. x is the vertex's x-component, or the axis of symmetry. Using the formula x=-b/2a, find the quadratic's vertex, and then substitute the result for y in the original equation. After that, enter the vertex as a variable in the vertex form equation, y=a(x-h)2+k. (A remains the same, h equals x, and K equals y.)The factored form of a quadratic expression is one in which the quadratic expression is the product of two factors, each of which is a linear expression. By extending it, which entails multiplying out the factors, a factored expression can be restated in standard form.To learn more about coordinates refer to:

Danielle's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 5 espressos in all, 5 of which were single-shot. What percentage of the espressos were single-shot?
write your answer using a percent sign (%)
100% percent of the espressos were single-shot.
What is the percentage?
Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios, proportions, and rates. It is denoted by the symbol "%". For example, if you have 25 out of 100 items, you can express this as 25% to represent the proportion of items that you have.
The total number of espressos sold yesterday afternoon was 5. If 5 of them were single-shot, then 100% * 5 / 5 = 100% of the espressos were single-shot.
Hence, 100% percent of the espressos were single-shot.

At pizza Pi, 30 percent of the pizza made last week had extra cheese. If 150 pizzas were made, how many pizza had extra cheese
As 30% of the pizza were made, we will have 500 pizzas that as extra cheese.
How do we calculate the number of pizza that has extra cheese?At Pizza Pi, the number of Pizzas that had extra cheese last week = 150
The percentage of Pizzas that had extra cheese last week = 30%
Now, let us assume that number of Pizzas made last week = X. Then, we will write the equation as:
30X/100 = 150
30X = (150 * 100)
30X = 15000
X = 15000/30
X = 500. Therefore, it can be deducted that 500 pizzas were made last week .

The majority of the data is in the center with the mean. D. The majority of the data is split to the right and left of the mean.
The majority of the data is split to the right and left of the mean.
What is normal distribution?The data is mostly divided to the right and left of the mean. The normal distribution is symmetric and continuous. Positively skewed data will have a higher mean than the median. If the data distribution is tilted to the left, the mean is less than the median, which is frequently less than the mode. A probability function that defines how the values of a variable are distributed is known as the normal distribution. The mean, median, and mode values in a normal distribution are all equal. So, in the context of a normal distribution curve, point (ii) is valid.

1. Find the length of an arc in a circle with a radius of 8 cm and a central angle of 197
On solving the provided question we can say that the radius of circle is 2.1415 cm.
What is circle?Every point in the plane that is a certain distance away from a certain point forms a circle (center). It is, thus, a curve formed by points moving in the plane at a fixed distance from a point. At every angle, it is also rotationally symmetric about the center. A circle is a closed two-dimensional object where every pair of points in the plane are equally spaced out from the "center." A line that goes through the circle creates a specular symmetry line. At every angle, it is also rotationally symmetric about the center.
We know, Central angle (θ) = (length arc)/radius ….(1)
Convert angle in radian:
Angle in radians = Angle in degrees x π/180° = 197° x π/180 = 1.09
From (1),
Radius = (length arc)/Central angle
= 8/3.1415 =2.1415cm

The family minivan can hold 14 gallons of gas. During a trip to the Seattle Zoo, the van uses 8.4 gallons of gas. What percent of the total gas was used?
Answer: To find the percent of gas used, we need to divide the amount of gas used by the total amount of gas the van can hold and multiply by 100.
Percent of gas used = (Gas used / Total gas) * 100
Given that the van uses 8.4 gallons of gas and can hold 14 gallons of gas, we can substitute these values into the formula:
Percent of gas used = (8.4 / 14) * 100
By performing this calculation we can get that the percent of gas used was: 8.4/14 = 0.6 = 60%
So, 60% of the total gas was used during the trip to the Seattle Zoo.
Step-by-step explanation:
Answer:
60%
Step-by-step explanation:
8.4 divided by 14 = 0.6. Let 1 be the 100%. Since 0.6 is the same as 0.60, we remove the decimal and make it 60.

y=x^2+6x+8 solve by completing the square.
For the given quadratic equation, the solutions are x = -3 and x = -3.
What is the completing square method?
The completing the square method is a technique used to solve quadratic equations of the form y = ax² + bx + c. The goal of this method is to convert the equation into the standard form of a quadratic equation, which is y = a(x + h)² + k, where a, h and k are constants.
To solve y = x² + 6x + 8 by completing the square, we need to add and subtract a value to the equation so that the x-term (x² + 6x) is a perfect square. In this case, we need to add and subtract (6/2)² = 9 to the equation, which gives us:
y = x² + 6x + 8
y = (x² + 6x + 9) - 1
Now, we can take the square root of the x-term, which is (x + 3)², and we get:
y = (x + 3)² - 1
The equation is now in the standard form of a quadratic equation, with y = (x + 3)² - 1. We can now solve for x by taking the square root of both sides of the equation and getting x = -3, -3 .
Alternatively, We can also solve for x by factoring the expression inside the square, which would give (x + 3) (x + 3) = 0 and x = -3, -3
Hence, for the given quadratic equation, the solutions are x = -3 and x = -3.

The first number is 5 less than 3 times the second number. Four times the first number
minus two times the second number is ten. Find the numbers.
Answer:
The first number is 4, the second is 3
Step-by-step explanation:
We can make 2 equations, let x be the first number, and y be the second number.
x = 3y - 5
4x - 2y = 10
We sub x = 3y - 5
=> 4(3y - 5) - 2y = 10
=> 12y - 20 - 2y = 10
=> 10y - 20 = 10
=> 10y = 30
=> y = 3
Sub y = 3 into x = 3y - 5
x = 3(3) - 5
x = 4
Therefore, the first number is 4, and the second is 3

This is the origin of the phrase hourly worker. Salary and commissions are some additional types of payment.
Pay for lower level employees is determined by the number of hours worked. To record the number of hours worked each week, these employees typically use a time sheet or time card. To keep track of hourly employee hours, the majority of modern employers use computerised systems.
To enter their hours worked, employees must log in and out of the system. These workers are then paid either weekly or biweekly, depending on the state.
Given that the owner pays herself twice the sum of the other employees' weekly wages.

Item Demand Probabilities(a) To find the probability that the item is requested more than 5 times on a given day, we would need to know the distribution of the demand for the item. Without that information, it is not possible to calculate this probability. This is because the average demand of 5 times per day does not provide enough information to determine the likelihood of the demand exceeding 5 times. We would need to know more information such as the standard deviation, skewness, kurtosis and the underlying distribution of the data, in order to calculate this probability.
(b) To find the probability that the item is not requested at all on a given day, we would also need to know the distribution of the demand for the item.

How do you find the ratio of a circle formula?
The ratio of a circle can be found through the formula A = πr2, where A is the area of the circle and r is the radius of the circle.
To find the ratio of a circle, you must first calculate the area of the circle. To calculate the area, multiply the value of π (3.14159) by the square of the radius (r2). For example, if the radius of the circle is 4, the area of the circle would be 3.14159 x 42, which is equal to 50.2653. The ratio of a given circle can then be found by dividing the area of the circle (50.2653) by the square of the radius (42), which gives 1.273.
