Using the table below, what is the y-intercept of the
parabola?
Answer:
The y-intercept of the table shown is (0, 1).
How to find a y-intercept of a parabola/equation?The y-intercept of the parabola can be found by verifying if any coordinates from the table has x = 0 and y = some specific value. If there is a coordinate point such that the value of both is x = 0 and y = any value, then the value of y is the y-intercept of the parabola. Further explained in example:
Example: if a line passes through a coordinate point (0, 4), the y-intercept for that line is four because the value of x is 0 and y is 4.
Solving the Problem/Question (Applying the method stated above):
From the table, we can tell that the parabola passes through the following coordinate points: (-2, -11); (-1, -4); (0, 1); (1, 4); (2, 5); (3, 4); (4, 1).
From all the coordinates, we find that (0, 1) has the value of x as 0 and the value of y as 1. Therefore, this coordinate point (0, 1) is the y-intercept.

Find three consecutive odd numbers whose sum is 1899.
Answer:
631, 633, 635
Step-by-step explanation:
Odd numbers exists in AP with common difference of 2.
That is; 1, 2, 5, 7 etc
So lets say the middle number of the three consecutive numbers is x, the next number to it Will be (x+2), and the previous number will be (x-2)
Therefore, the sequence is (x-2), x, (x+2) ... (1)
and the series will be, (x+
-2) + x + (x+2) = 1899
Solve for x;
x + x + x - 2 + 2 = 1899
3x + 0 = 1899
x = 1899 ÷ 3
x = 633
Therefore the consecutive odd numbers (following 1) is: (633 - 2), 633, (633+2) = 631, 633, 635

The outpatient surgery as the percent of total surgeries in the year 1996 is 86 %
What is logarithmic function ?The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.
According to the given information
Consider the logarithmic function:
[tex]f(x)=-1311+306 \ln x[/tex]
Here x is the number of years since 1990 and f(x) is the outpatient surgery as the percent of total surgeries.
In the year 1996:
[tex]& x=96 \\[/tex]
[tex]& f(96)=-1311+306 \ln (96) \\[/tex]

Answer:
3. (x, y) = (20, 30)
4. (x, y) = (30, 4)
Step-by-step explanation:
You have equilateral triangles in two different configurations, and you want to find the values marked x and y.
3.All of the angles marked with an arc are congruent, so all are 60°. The angle marked 80° is an external angle to the top/left triangle. Its value is the sum of the values of the remote interior angles:
80° = 60° +x°
20° = x° . . . . . . . subtract 60°
x = 20
The sides of the equilateral triangle are congruent, so all are length 46. That means the right side is ...
16 +y = 46
y = 30 . . . . . . . subtract 16
(x, y) = (20, 30)
4.All of the angles marked with an arc are congruent, so all are 60°. The top 60° angle of the equilateral triangle is an external angle to the isosceles triangle at top/right. Its two base angles are the remote interior angles with respect to that 60° exterior angle, so their sum is 60°:
x° +x° = 60°
x = 30
The two marked legs of the isosceles triangle are both 20, which means all sides of the equilateral triangle are length 20.
5y = 20
y = 4 . . . . . . . divide by 5
(x, y) = (30, 4)

What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.
Given is that there are two times the amount of milk chocolate bars as there are dark chocolate bars in a box. There are a total of 138 candy bars in the box.
Assume that there are [x] chocolate bars in the box. Then, there will be [2x] milk bars. So, we can write -
2x + x = 138
3x = 138
x = 138/3
x = 46
Therefore, there are 46 chocolate bars and (2 x 46) or 92 milk bars in the candy box.

Find a solution to the linear equation y=2x+6 by filling in the boxes with a valid value of x and y.
Answer:
The answer to the linear equation y = 2x + 6 is (x, y) = (1, 2.5). This means that if we plug in x = 1 into the equation, we get y = 2.5.
Step-by-step explanation:
To find the solution to the linear equation y = 2x + 6, we can first rewrite the equation in slope-intercept form. This is done by rearranging the equation to have the form y = mx + b, where m is the slope of the line and b is the y-intercept.
In this case, we have y = 2x + 6. To put this equation in slope-intercept form, we need to isolate the y-term on one side of the equation. We can do this by subtracting 2x from both sides, which gives us y - 2x = 6.
Next, we need to divide both sides of the equation by the coefficient of the y-term, which is -2 in this case. This gives us the equation y = -(1/2)x + 3.
Finally, we can plug in any value of x that we want to find the corresponding value of y. For example, if we plug in x = 1, we get y = -(1/2) * 1 + 3 = 2.5. Therefore, the solution to the equation y = 2x + 6 is (x, y) = (1, 2.5).
In general, if we want to find the solution to a linear equation in slope-intercept form, we can plug in any value of x that we want to find the corresponding value of y. This process is called graphing the line, and it is a useful way to visualize the solutions to linear equations.

To calculate the height of the model, the architect should [divide] the actual height of the building by [10]
The height of the model is [6] inches.
How to complete the statement explaining how to find the height of the model the architect made?A scale is a factor by which a quantity is multiplied or divided in order to change its magnitude. Scales are commonly used to change the size of a figure without changing its shape or orientation.
Given:
A scale = 1 inch represents 10 feet
The height of the actual building = 60 feet
Since the model is a smaller version of the actual building, in order to get the height of the model, you have to divide the height of the actual building by the scale (10).
Thus, height of the model = 60/10 = 6 inches

ABCD is a rectangle.
ABCD is a square.
ABCD is a rhombus.
ABCD is none of these.
The parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3) is a rectangle as two sides are equal, so option A is correct.
What is parallelogram?A unique kind of quadrilateral created by parallel lines is called a parallelogram. A parallelogram can have any angle between its neighboring sides, but for it to be a parallelogram, its opposite sides must be parallel.
Given data:
The parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3),
Calculate the distance of sides as shown below
[tex]AB = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
AB = [tex]\sqrt{[-7-(-8)]^2 + (8-5)^2}[/tex]
AB = √(1² + 3²)
AB = √10
Calculate
BC = [tex]\sqrt{[-1-(-7)]^2+(6 - 8)^2}[/tex]
BC = √(36 + 4)
BC = √40 or 2√10
Similarly,
CD = √10
And AD = 2√10
Here AB = CD and BC = AD, opposite sides equal, so it is a rectangle. Therefore, the parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3) is a rectangle as two sides are equal.
