Finish the steps below to write a quadratic function for the parabola shown. Use the vertex form, f(x) = a(x – h)2 + k, and substitute in the values for h and k. f(x) = a(x – 5)2 + 3 Use another point and substitute in values for x and f(x). Solve for a. 5 = a(6 – 5)2 + 3 Write the function, using the values for h, k, and a. The function is f(x) = (x – )2 + .

Answers

we have

f(x) = a(x – h)² + k
 we know the vertex v(5,3)
substitute in the values for h and k
f(x) = a(x – 5)² + 3 
Use another point and substitute in values for x and f(x). 
for the point (6,5)
Solve for a.
5 = a(6 – 5)2 + 3-------------- > 5=a+3-------------> a=2

The function is f(x)=a(x – h)2 + k-------- > 2(x – 5)² + 3
f(x)= 2(x – 5)² + 3-------- > 2[x²-10x+25]+3=2x²-20x+50+3=2x²-20x+53
f(x)=2x²-20x+53

the answer is f(x)= 2(x – 5)² + 3----------------- > (f(x)=2x²-20x+53)

Here we want to write the quadratic function for the parabola shown in vertex form.

We will get the function: f(x) = 2*(x - 5)^2 + 3

So the general function of a parabola with vertex (h, k) and leading coefficient a is:

f(x) = a*(x - h)^2 + k

Here, we know the formula:

f(x) = a*(x - 5)^2 + 3

where:

h = 5k = 3

So the vertex is the point (5, 3), and we only must find the value of a to completely determine the parabola's function

We also know that:

f(6) = 5

So we can solve:

5 = a*(6 - 5)^2 + 3

5 = a*(1)^2 + 3

5 = a + 3

5 - 3 = a = 2

So we just found the value of a, replacing this on the parabola's function we get:

f(x) = 2*(x - 5)^2 + 3

what are the properties of real numbers?

Answers

Final answer:

The properties of real numbers include closure, commutative, associative, identity, and inverse properties. These properties govern how real numbers behave in addition and multiplication operations.

Explanation:

The properties of real numbers refer to the characteristics and behavior of numbers that belong to the real number system. The real number system includes all rational and irrational numbers, such as whole numbers, integers, fractions, decimals, and square roots.

The properties of real numbers include:

Closure property: The sum or product of any two real numbers is also a real number. For example, the sum of 3.14 and 4 is 7.14, which is a real number.Commutative property: The order of addition or multiplication does not affect the result. For example, 2 + 3 is equal to 3 + 2, and 2 × 3 is equal to 3 × 2.Associative property: The grouping of real numbers in addition or multiplication does not affect the result. For example, (2 + 3) + 4 is equal to 2 + (3 + 4), and (2 × 3) × 4 is equal to 2 × (3 × 4).Identity property: The sum of a real number and zero is equal to the number itself. For example, 2 + 0 is equal to 2. The product of a real number and one is equal to the number itself. For example, 3 × 1 is equal to 3.Inverse property: Every real number has an additive inverse and a multiplicative inverse. The additive inverse of a real number is the number that, when added, gives zero as the result. For example, the additive inverse of 5 is -5, as 5 + (-5) = 0. The multiplicative inverse of a non-zero real number is the number that, when multiplied, gives one as the result. For example, the multiplicative inverse of 2 is 1/2, as 2 × (1/2) = 1.

These properties of real numbers are fundamental in algebraic operations and calculations. They provide a basis for solving equations, simplifying expressions, and working with mathematical concepts.

Find the volume of a box that will hold nine 9.425 cm3 cylindrical containers that each measure 3 centimeters long. (round to nearest whole number)

Answers

To find the volume of a box that would hold these nine cylinders, you would start with the formula for volume of a cylinder. V=pi x r^2 x h. Substitute in the known volume and the known Height. 9.425=pi x r^2 x 3. Divide both sides by three to get approximately 3.143 = pi x r^2. Divided by pi on both sides. This leaves you with one = r^2. So the radius is equal to one. If the radius equals one, the diameter is two. Assuming the cylinders are arranged in a 3 x 3 array, the length and width of the rectangle or box would be 6cm x 6cm. To find the volume of the box necessary, multiply the length of six by the width of six by the height of three. The volume would be 108 square cm.

Final Answer:

The volume of the box that will hold nine 9.425 cm³ cylindrical containers, each measuring 3 centimeters long, is approximately 108 cm³.

Explanation:

First, we need to find the radius of each cylindrical container since we have its volume and the length. The volume V of a cylinder is given by the formula:
[tex]\[ V = \pi r^2 h \][/tex]
where r is the radius and h is the height (or length) of the cylinder. We are given:
[tex]\[ V = 9.425 \text{ cm}^3 \\\\\[ h = 3 \text{ cm} \][/tex]

We need to solve for r:

[tex]\[ 9.425 = \pi r^2 (3) \\\\\[ r^2 = \frac{9.425}{3\pi} \\\\\[ r^2 = \frac{9.425}{3 \times 3.14159} \\\\\[ r^2 = \frac{9.425}{9.42477} \\\\\[ r^2 \approx 1 \\\\\[ r \approx 1 \text{ cm} \][/tex]

Now we know the radius of one cylindrical container is approximately 1 cm. Although this rounding might lead to a slightly inaccurate result, we'll proceed with this approximation for simplicity's sake.

Since each container is a cylinder with a radius of 1 cm, the diameter of each container is [tex]\( 2 \times 1 = 2 \)[/tex] cm. If we wanted to pack these containers without any wasted space in one layer, we would arrange them in a 3 by 3 grid, given there are 9 containers. The length and the width of the box would then each be 3 times the diameter of one container.

Hence:
Length of box = Width of box = [tex]\( 3 \times 2 \)[/tex] cm = 6 cm.
The height of the box would be equal to the length of one of the containers, which is 3 cm.

Now we can find the volume of the box:
Volume of box [tex]\( V_{\text{box}} \) = Length \( \times \) Width \( \times \) Height[/tex]
[tex]\[ V_{\text{box}} = 6 \text{ cm} \times 6 \text{ cm} \times 3 \text{ cm} \\\\\[ V_{\text{box}} = 36 \text{ cm}^2 \times 3 \text{ cm} \\\\\[ V_{\text{box}} = 108 \text{ cm}^3 \][/tex]
Rounding to the nearest whole number, the volume of the box that will hold nine 9.425 cm³ cylindrical containers, each measuring 3 centimeters long, is approximately 108 cm³.

What are ratio and proportion?

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Conversion means to convert the same thing into different units.

If apples are on sale at 15 for $3.

We know that $1 = 100 cents

Then the number of the cents in 3 dollars will be

⇒ 3 x 100

⇒ 300 cents

Then the cost of each apple will be the ratio of the 300 cents and 15 apple.

⇒ 300 / 15

⇒ 20 cents per apple

Thus, the cost of each apple will be 20 cents per apple.

Then the correct option is C.

In graph 2, the dots are scattered and also no association.

What is an association?

An association (relationship) between two numerical variables can be described by its form, direction, strength, and outliers. A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables.

For the given situation,

There are four new consignments of t-shirts.

Each consignment contained t-shirts of five different sizes.

Graph is plotted as shown below between each of the t-shirt sizes and the profit earned on each new size.

If one variable increases as the other variable increases, there is said to be a positive association.

Two variables have a negative association when the values of one variable tend to decrease as the values of the other variable increase.

No association means that there is no line and all the dots are scattered.

From the graph shown, in graph 2 the dots are scattered. Thus no  association.

Hence we can conclude that in graph 2, the dots are scattered and also no association.

Answer:
The second choice is the correct one

Explanation:
(2x+3)^2 + 8(2x+3) + 11 = 0
To use the u substitution, we will assume that:
2x + 3 = u

Substitute with this in the given expression, we will get:
u^2 + 8u + 11 = 0 

The general form of the second degree equation is:
ax^2 + bx + c = 0

Comparing the expression we reached with the general one, we will find that:
a = 1
b = 8
c = 11

The roots can be found using the rule found in the attached picture.
This means that, for the given expression:
u = -4 ± √5 

Now, we have:
u = 2x+3
This means that:
at u = -4 + √5 
2x + 3 = -4 + √5 
2x = -7 + √5
x = (-7 + √5) / 2

at u = -4 - √5 
2x + 3 = -4 - √5 
2x = -7 - √5
x = (-7 - √5) / 2

This means that, for the given expression:
x = (-7 ± √5 ) / 2

Hope this helps :)
(2x + 3) ^ 2 + 8 (2x + 3) + 11 = 0
 Using substitution we have:

 We use resolvent:
 u = (- b +/- root (b ^ 2 - 4ac)) / (2a)
 We replace:
 u = (- (8) +/- root ((8) ^ 2 - 4 (1) (11))) / (2 (1))
 u = (- (8) +/- root (64 - 44)) / (2)
 u = (- (8) +/- root (20)) / (2)
 u = (- (4) +/- root (5))
 We return the change:
 u = (- (4) +/- root (5)) = 2x + 3

The perimeter of a rectangle is 54cm. The area of the same rectangle is 176 cm^2. What are the dimensions of the rectangle?

A. 11 cm by 16 cm
B. 8 cm by 22 cm
C. 5.5 cm by 32 cm
D. 4 cm by 44 cm

Answers

Given is rectangle with perimeter = 54 centimeters and area = 176 squared centimeters.

Let's consider the length of rectangle = L and width of rectangle = W.

We know the following formulas for rectangle :-

Perimeter = 2 x (L + W)

Area = L x W

So we have 2 x (L + W) = 54 and L x W = 176.

L + W = 27 and L x W = 176

We need to find two positive integers such that their sum is 27 and product is 176.

Using trial and error, we have two such positive integers such that 11 + 16 = 27 and 11 x 16 = 176.

So, the dimensions of rectangle would be 11cm x 16cm.

Hence, option A is correct i.e. 11 cm by 16 cm.

Input in standard form the equation of the given line. The line with m=1/2 and b=3

Answers

The standard form of the equation of a line is ax + by = c, where a b and c are integers.

You are given a slope of m = 1/2 and b = 3. Note that m is used in the slope intercept form of a line, so let's first express this using slope intercept form of for a line, which is y = mx + b.
Plugging in given values you get
y = (1/2)x + 3.

Standard form requires coefficients to be integers, so multiply both sides by 2 to get rid of the fraction.
2y = x + 6

Finally reorder the terms. Subtract both sides by 2y then subtract both sides by 6.
x - 2y = -6

Final answer:

To find the equation of a line with a given slope and y-intercept in standard form, substitute the values of the slope and y-intercept into the equation y = mx + b.

Explanation:

To write the equation of a line given the slope m and y-intercept b in standard form y = mx + b, you can directly substitute the values of m = 1/2 and b = 3 into the equation.

Substitute m = 1/2 and b = 3 into y = mx + b: y = (1/2)x + 3

Therefore, the equation of the line in standard form is y = (1/2)x + 3.

x = sq rt. 25(10) / 5

x = 5 sq rt. 10 /5

The five would be cancelled resulting to:

x =sq rt. 10

Rachel pays $131.44 for a desk, including tax. The task is 31 cents less than 1*16 the desk’s price. What is the price for the desk before adding the tax?

Answers

Answer:

The cost of the desk is 124 dollars.

Step-by-step explanation:

irst, change this into an equation

tax=1/16x-.31


x equals the cost of the desk without tax:

x+tax=131.44

tax=131.44-x


Set the first equation equal to the second:

1/16x-.31=131.44-x


Solve for x:

17/16x=131.75

x=$124


Hope that helps

The equivalent percentage value for the decimal number 1.16 is 116% which is obtained by multiplying the decimal by 100. Before including the tax the price of the desk was $60.99.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

And to convert a fraction or a decimal into percentage, they are multiplied by 100.

Given that,

The amount paid by Rachel for a desk is $131.44.

Suppose the price of desk is before adding the tax is x.

Then, as per the problem the following expression can be written for the tax amount as,

1.16x - 0.31  

Now, the expression for the price of desk after tax is,

x + 1.16x - 0.31  = 131.44

⇒ 2.16x =  131.44 +  0.31

⇒ 2.16x = 131.75

⇒ x = 131.75 / 2.16

⇒ x = 60.99

Hence, the price for the desk before adding the tax is $60.99.
