The equation of the parabola exists y = 3/80(x - 20)² - 15

In the coordinate plane, a parabola exists algebraically represented using the standard equation. A parabola's general equation exists written as,

y = a(x - h)² + k

where (h, k) signifies the vertex.

y² = 4ax is the typical equation for a normal parabola.

substitute the values in the above equation, we get

y = a(x - 20)² - 15

simplifying the above equation, we get

0 = a(0 - 20)² - 15

0 = 400a - 15

a = 15/400

a = 3 / 80

Therefore, the equation of the parabola exists y = 3/80(x - 20)² - 15.

The mean of the data is 3.85 using the stem-and-leaf plot.

It means the average feet that the heavy ball was thrown is 3.85 feet, which is the typical number.

To find the mean of a data set that is represented by a stem-and-leaf plot, first, list out all the data values that are represented on the stem-and-leaf plot, add all the values, and divide by the number of values that were represented on the stem-and-leaf plot.

Given the stem-and-leaf plot, using the key, the data points represented are:

2.0, 2.1, 2.4, 3.1, 3.2, 3.6, 4.1, 4.3, 4.7, 5.1, 5.1, 6.5

Mean = [2.0 + 2.1 + 2.4 + 3.1 + 3.2 + 3.6 + 4.1 + 4.3 + 4.7 + 5.1 + 5.1 + 6.5]/12

Mean = 46.2/12

Mean = 3.85 feet

The mean of 3.85 feet means that the average distance that the heavy ball was thrown in feet is 3.85.

Answer:

I believe the first one is log8(5/3), the second is log5(3), and the third is -2log2(5)

Step-by-step explanation:

I got this by applying the properties of logarithms which are:

logₐ mn = logₐ m + logₐ n (product property)

logₐ m/n = logₐ m - logₐ n (quotient property)

logₐ mn = n logₐ m (power property)

logb = (log꜀ a) / (log꜀ b) (change of base property)

The circumference of the circle is 21.98cm and the area of the circle is 38.465 square cm.

Circumference of the circle:

The Circumference (also known as) perimeter of circle = 2πR

where,

R is the radius of the circle

π is the mathematical constant with an approximate value is 3.14.

Area of circle:

The formula to find the area of the circle is;

A = πr²

Where r represents the radius of the circle.

Given,

The diameter of the circle is 7 cm.

Here we need to find the circumference and the area of a circle.

Here we have the value of diameter, in order to find the circumference we have to find the value of radius that can be derived by dividing the diameter by 2.

So, the radius is

=> 7/2 = 3.5

Now the circumference of the circle is calculated as,

C = 2 x π x 3.5

When the value of π = 3.14

Therefore, the circumference of the given circle is,

=> C = 2 x 3.14 x 3.5

=> C = 21.98

Now, the area of the circle is,

=> A = π x (3.5)²

=> A = 3.14 x 12.25

=> 38.465

Therefore, the area of the circle is 38.465 square cm.

For the given points (6, y) and (-8, 4) having slope = 1/7 the value of y = 10.

What is the slope of a line?

A line's slope, also known as its gradient, is defined as the value of a line's steepness or direction in a coordinate plane. Slope can be calculated using various methods given a line equation or the coordinates of points on a straight line.

If P(a, b) and Q(c, d) are two given points on a coordinate plane, then the slope of line PQ can be computed using the formula

                      [tex]Slope(m)=\frac{d - b}{ c - a}[/tex]

The given points are (6, y) and (-8, 4).

and the slope of the line is given as m = 7.

By using the slope of a line formula, we get

                       [tex]m = \frac{8-y}{-8-7}\\\\ \frac{1}{7}= \frac{8-y}{-8-7}\\\\\frac{1}{7}= \frac{8-y}{-14}\\\\\\8-y=-2\\y=8+2\\y=10[/tex]

One bag of cat food costs $6 and one bag of dog food costs $9.

What is system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

The problem states that c equals the cost of bag of cat food and d equals the cost of bag of dog food.

Last week she paid $117 for 6 bags of cat food and 9 bags of dog food.

Therefore, the equation becomes,

6c + 9d = 117         ..(1)

This week she paid $87 for 4 bags of cat food and 7 bags of dog food.

Therefore, the equation becomes,

4c + 7d = 87         ..(2)

Now to solve the system of equations

To solve the first equation for c.

6c + 9d = 117

6c = 117 - 9d

[tex]c = \frac{117}{6}-\frac{9d}{6}[/tex]

Plug value of c in equation (2).

[tex]4(\frac{117}{6}-\frac{9d}{6}) +7d = 87\\78 - 6d + 7d = 87\\d = 87-78\\d = 9[/tex]

Plug d = 9 in equation (1)

6c + 9(d) = 117

6c + 9(9) = 117

6c + 81 = 117

6c = 117 - 81

6c = 36

c = 6

Hence, one bag of cat food costs $6 and one bag of dog food costs $9.

Given data

A driveway is being surfaced with concrete pavers in the shape of regular hexagons. If the driveway is a 24-by-26-foot rectangle with pavers 6 inches wide across the flats.

We have to determine how many pavers are needed

We know that area of a regular hexagon

A = (3√3)/2 a^2

= (3√3)/2 〖(6)〗^2

= (3 x 1.732)/2  x 36

= 93.528 sq.inches

Now area of rectangle

= l x w

= 24 x 26 x (12)2        (1feet = 12 inches)

A scatterplot is also referred to as scatter diagram, scattergram, or scatter chart and it can be defined as a type of graph which is used for the graphical representation of the values of two (2) variables, with the resulting points showing any association between the data set.

For this exercise, the height (M) was plotted on the x-axis of the scatterplot (graph) while the weight (in kg) would be plotted on the y-axis of the scatterplot (graph).

From the scatterplot which models the relationship between the height (M) and weight (in kg) of a person, an equation for the line of best fit is given by:

Weight, kg = -114.3 + 106.5M

When M = 1.4 meters, we have the following weight:
