Using the function rule y = 5 + 5x, we can fill in the table as follows:
x | y
0 | 5
1 | 10
2 | 15
3 | 20
4 | 25
To fill in the table using the function rule y = 5 + 5x, we can substitute different values of x into the equation and calculate the corresponding values of y.
Let's create a table:
x | y
0 | 5 + 5(0) = 5 + 0 = 5
1 | 5 + 5(1) = 5 + 5 = 10
2 | 5 + 5(2) = 5 + 10 = 15
3 | 5 + 5(3) = 5 + 15 = 20
4 | 5 + 5(4) = 5 + 20 = 25
Using the function rule y = 5 + 5x, we can substitute each value of x into the equation to find the corresponding value of y. For example, when x = 0, y = 5. When x = 1, y = 10, and so on.
Therefore, the completed table is:
x | y
0 | 5
1 | 10
2 | 15
3 | 20
4 | 25
These values satisfy the given function rule y = 5 + 5x.

Answer:
the best value for the percentage of the area under the curve that is shaded is 68%.
Step-by-step explanation:
Approximately 68% of the data falls within one standard deviation of the mean.
Approximately 95% of the data falls within two standard deviations of the mean.
Approximately 99.7% of the data falls within three standard deviations of the mean.
Given that the mean is 170.8 min and the standard deviation is 19.7 min, we can calculate the values of U, V, and W.
U: U is one standard deviation below the mean.
U = Mean - 1 * Standard Deviation
U = 170.8 - 1 * 19.7
U ≈ 151.1
V: V is the mean.
V = Mean
V = 170.8
W: W is one standard deviation above the mean.
W = Mean + 1 * Standard Deviation
W = 170.8 + 1 * 19.7
W ≈ 190.5
Now, let's determine the best value for the percentage of the area under the curve that is shaded. Based on the empirical rule, the highest percentage that can be shaded is approximately 68% since it represents the data within one standard deviation of the mean.
Therefore, the best value for the percentage of the area under the curve that is shaded is 68%.

The missing angle measurements are:
Angle G = 66.67 degrees
Angle H = 113.32 degrees
Angle Z = 66.68 degrees
Angle I = 66.68 degrees
Let's analyze the given information and solve for the missing angle measurements:
From the diagram, we can see that angle H and angle G are adjacent angles, and the line segment HG acts as a transversal. We are given that the measure of angle G is 2x, and we need to find the missing angle measurements, which are the measures of angle H, angle Z, and angle I.
Since angle G and angle H are adjacent angles, their measures add up to 180 degrees. So we can set up the equation:
2x + (4x - 20) = 180
Simplifying the equation:
6x - 20 = 180
Next, we solve for x:
6x = 200
x = 200/6
x = 33.33
Now that we have found the value of x, we can substitute it back into the original equation to find the measures of the missing angles:
Angle G = 2x = 2(33.33) = 66.67 degrees
Angle H = 4x - 20 = 4(33.33) - 20 = 133.32 - 20 = 113.32 degrees
Angle Z = 180 - Angle H = 180 - 113.32 = 66.68 degrees
Angle I = Angle Z = 66.68 degrees

The given points are A (-2, 1) and B (3, 4).
We need to determine the coordinates of point C in the fourth quadrant such that m∠CAB=90° and AB=AC.
In order to determine the coordinates of point C,
The slope of ABThe slope of the line passing through A(-2, 1) and B(3, 4) is given bym = (y₂ - y₁) / (x₂ - x₁)m
= (4 - 1) / (3 - (-2))m
= 3 / 5
The mid-point of A and BMid-point of A and B is given by the following formula:
Mid-point = ((x₁ + x₂)/2, (y₁ + y₂)/2)
Mid-point of AB is: ((-2 + 3) / 2, (1 + 4) / 2)
= (1/2, 5/2)
The slope of the line perpendicular to AB
The slope of the line perpendicular to AB is given by the following formula: m₁ * m₂ = -1
Where m₁ is the slope of AB and m₂ is the slope of the line perpendicular to ABm₁ = 3 / 5m₂ = - 5 / 3 (as the line is perpendicular to AB and the product of slopes of two perpendicular lines is -1)

Let the coordinates of C be (x, y)We know that AC = AB and we know the coordinates of A (-2, 1) and mid-point of AB (1/2, 5/2).
Simplifying this equation, we get:
15b = 47b = 47 / 15
Substituting this value of b in the equation we got earlier:

What is quadratic formula?
Quadratic formula is a formula that gives the solutions of the general quadratic equation ax² + bx + c = 0 and that is usually written in the form
x = (-b ± √(b2 − 4ac))/(2a)
From the question, the initial height, h, of the ball is 40 ft
When the ball hits the ground, the height, h, is zero
The equation h = - 16t² + 15t + 40 becomes
0 = - 16t² + 15t + 40
16t² - 15t - 40 = 0
Solving the quadratic equation by formula method for t,
t = (-b ± √(b² - 4ac)) / (2a)
Where, a = 16, b = -15, and c = -49
Substitute these values into the quadratic formula,
t = (15 ± √2785) / 32
Therefore, the possible values of t are:
t = (15 + √2785) / 32
t = (15 - √2785) / 32
Which implies t = 2.12 or t = - 1.18
Since time, t, cannot be negative, t = 2.12s to the nearest hundredth.

The simplified expression is 6 raised to the power of
.
The value of the simplified expression is
.
The simplified expression is 1,675,616. the value of the expression is 1,675,616.
To find the simplified expression and the value of 6 raised to a power, follow the steps given below:
Step 1: Simplify the expression Firstly, the simplified expression is obtained by using the rule of exponents, which states that if a number raised to a power is multiplied by the same number raised to another power, then the resulting power is the sum of the two powers.
6 raised to the power of 2 is 6 × 6 = 36.6 raised to the power of 3 is 6 × 6 × 6 = 216.6 raised to the power of 4 is 6 × 6 × 6 × 6 = 1296.6 raised to the power of 5 is 6 × 6 × 6 × 6 × 6 = 7776.
Step 2: Find the value of the expression
From these results, it can be seen that when 6 is raised to an even power, the resulting number is even, and when 6 is raised to an odd power, the resulting number is odd. This is because 6 is an even number.
In general, if a number is even, then the result obtained when it is raised to an even power is even, and the result obtained when it is raised to an odd power is odd.
If a number is odd, then the result obtained when it is raised to any power is odd. 6 raised to the power of 8 can be written as 6 raised to the power of 4 raised to the power of 2, as shown below 6 raised to the power of 8 = (6 raised to the power of 4) raised to the power of 2= 1296 raised to the power of 2= 1,675,616

A 16 ounce bottle of spring water is $2.08. A 20 ounce bottle of fresh water is $2.40 Therefore, this statement "A 20 ounce bottle of fresh water is $2.40" is true.
To determine which statement is true, let's compare the prices of the two water bottles:
16 ounce bottle of spring water: $2.08
20 ounce bottle of fresh water: $2.40
To find the price per ounce for each water bottle, we can divide the total price by the number of ounces:
Price per ounce of spring water: $2.08 / 16 ounces = $0.13 per ounce
Price per ounce of fresh water: $2.40 / 20 ounces = $0.12 per ounce
Comparing the prices per ounce, we can see that the price per ounce of fresh water ($0.12) is less than the price per ounce of spring water ($0.13).

A particular restaurant can legally have only 150 people in it at one time. The tables in the restaurant can seat 4 people at a time. The number of tables, t, in the restaurant can be represented by the inequality 4t < 150. What is the maximum number of tables the restaurant can have?
.
The maximum number of tables the restaurant can have is 37. This ensures that the total number of people seated at the tables (37 * 4 = 148) is less than the legal limit of 150 people in the restaurant at one time.
To find the maximum number of tables the restaurant can have, we need to solve the inequality 4t < 150.
Dividing both sides of the inequality by 4, we have:
t < 150/4
Simplifying the right side, we get:
t < 37.5
Since the number of tables must be a whole number, we can conclude that the maximum number of tables the restaurant can have is 37.
Let's verify this by substituting t = 37 into the original inequality:
4t < 150
4(37) < 150
148 < 150
Since 148 is less than 150, the inequality holds true. However, if we increase the number of tables to 38, we get:
4(38) < 150
152 < 150
In this case, 152 is not less than 150, so the inequality is no longer satisfied.

The rectangular tank shown below was 4/5 filled with water. how many more litres of water were needed to fill up the tank?
The volume of water required to fill up the tank is: 540 cm³
How to find the volume of the cuboid?The formula for the volume of a cuboid is:
Volume = Length * Width * Height
Thus:
Volume of bigger tank = 15 * 15 * 12
Volume = 2700 cm³
Now, we are told that it is 4/5 filled with water.
Thus, volume needed to fill up the tank is:
¹/₅ * 2700
= 540 cm³

Which description does NOT guarantee that a quadrilateral is a parallelogram?
a quadrilateral with consecutive angles supplementary
a quadrilateral with the diagonals bisecting each other
a quadrilateral with both pairs of opposite sides congruent
quadrilateral with two opposite sides parallel
The description that does NOT guarantee that a quadrilateral is a parallelogram is:
a quadrilateral with consecutive angles supplementary.Why the statement is not a guaranteeWhile it is true that consecutive angles in a parallelogram are supplementary (their sum is 180 degrees), the converse is not true. In other words, having consecutive angles that are supplementary does not necessarily imply that the quadrilateral is a parallelogram.
There are other types of quadrilaterals, such as trapezoids or irregular quadrilaterals, that can also have consecutive angles that are supplementary.
