Step-by-step explanation:

Given:

Post office is located at P(1,5).

Market is located at Q(4,9).

To find:

Distance between the post office and the market.

Solution:

Distance between two points is:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The post office is located at P(1,5) and the market is located at Q(4,9). So, the distance between the post office and the market is:

[tex]PQ=\sqrt{(4-1)^2+(9-5)^2}[/tex]

[tex]PQ=\sqrt{(3)^2+(4)^2}[/tex]

[tex]PQ=\sqrt{9+16}[/tex]

[tex]PQ=\sqrt{25}[/tex]

[tex]PQ=5[/tex]

The axes show distance in miles.

Therefore, the distance between the post office and the market is 5 miles.

Given:

The graph of a parabola.

To find:

The domain, range and check whether it is a function or not.

Solution:

Domain: The set of x-values or input values is known as domain.

Range: The set of y-values or output values is known as range.

A relation is a function if their exist unique outputs for each input. In other words a graph is a relation if it pass the vertical line test.

Vertical line test: Each vertical line intersect the graph at most once.

The given function is defined for all real values of x which are greater than or equal to -3. So, the domain of the given graph is:

[tex]Domain=[-3,\infty)[/tex]

The given function values can be any real number. So, the range of the given graph is:

[tex]Range=(-\infty,\infty)[/tex]

For x=0, we have two values of the function because the graph intercept the y-axis at two points.

Since the graph does not pass the vertical line test therefore the given graph is not a function.

Step-by-step explanation:

C1 = 180 - C2

= 180 -  (170-2x)

= 10 + 2x

So B3 = 10+2x (alternate angles).

and B2 = 90 - B3

= 90 - (10 + 2x)

= 80 - 2x.

To do this, we simply consider the intervals of the hair lengths where they are lots of data; i.e. where frequency is greater than 1

For the first cluster, we can select the following interval

[tex]\frac{1}{2} \to 2[/tex]

Because;

hair length [tex]\frac{1}{2}[/tex] has a frequency of 3

and the data continues till hair length 2 which has a frequency of 2

For the second cluster, we can select the following interval

[tex]3\frac{1}{2} \to 4\frac{1}{2}[/tex]

Because;

hair length [tex]3\frac{1}{2}[/tex] has a frequency of 3

and the data continues till hair length [tex]4\frac{1}{2}[/tex] which has a frequency of 2

Note that, hair lengths with 0 or 1 as their frequency were not selected as part of the cluster

Answer:

MJ = 6.5

Step-by-step explanation:

Tangent lines to a circle are perpendicular to the radius.

tan 68° = JL/3

2.4751 = JL/3

JL = 7.4253

∠JLK = 90° - 68° = 22°

∠MLJ = 61° - 22° = 39°

sin 61° = MJ/7.4253

MJ = 7.4253(0.8746) =  6.5

The length of radius MJ is 5.99 units

Start by calculating the length JL using the following tangent ratio

tan(68°) = JL/3

Make JL the subject

JL = 3 * tan(68°)

Evaluate the product

JL = 7.4

From the figure, the measure of angle MLJ is:

∠MLJ = MLK - JLK

Where:

∠JLK = 90° - 68° = 22°

So, we have:

∠MLJ = 61 - 22

∠MLJ = 39

The radius MJ is then calculated using the following tangent ratio

tan(39) = MJ/JL

This gives

tan(39) = MJ/7.4

Make MJ the subject

MJ = 7.4 * tan(39)

Evaluate

MJ = 5.99

Hence, the length of radius MJ is 5.99 units

Answer: THIS IS SO HARD!

Step-by-step explanation:

The required boiling temperature of platinum is 3,739 degrees Celsius.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

Here,
a. Let's start by defining a variable for the boiling temperature of zinc, which we'll call z.

According to the problem statement, the boiling temperature of platinum is 199 more than four times the boiling temperature of zinc. In other words,

Boiling temperature of platinum = 4z + 199

So the expression that represents the boiling temperature of platinum in degrees Celsius is:

4z+199

b. The problem tells us that the boiling temperature of zinc is 907 degrees Celsius. So we can substitute this value for z in our expression:

4z+199 = 4(907)+199 = 3,739

Therefore, the boiling temperature of platinum is 3,739 degrees Celsius.

Answer: C

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

She actually earned 21 credits, which means she earned at least 4.

Lauri earned 4 credits for the year is false.

A division is a process of splitting a specific amount into equal parts.

To earn one Social Security credit, a person needs to earn a certain amount of money each year.

The amount needed for one credit changes each year and is determined by the Social Security Administration.

Given that last year Lauri earned $23,000 and earned 4 credits, we can calculate how much money she earned per credit by dividing her total earnings by the number of credits earned:

$23,000 / 4 credits = $5,750 per credit

Now we can check if $5,750 is equal to $1,090, the amount needed for one credit according to the problem.

$5,750 is not equal to $1,090, so the statement is false.

Hence,  Lauri earned 4 credits for the year is false.

[tex]525\pi[/tex]

Step-by-step explanation:

Volume of a cylinder is given by the function [tex]v=\pi r^{2}h[/tex]

where v is volume, r is radius and h is height.

In order to find the radius we just divide the diameter in half and get

[tex]\frac{10}{2} =5=r[/tex]

now we just plug the values in the formula

[tex]v=\pi r^{2}h\\=\pi (5^{2})(21)\\=\pi (25)(21)\\=525\pi[/tex]

Answer:

Volume of a cylinder: V = π (r^2) h

Step-by-step explanation:

First, find your radius and your height.

H = 21

D = 10

R = 1/2 d = 5

Then plug them into the equation: V = π (r^2) h

V = π (5^2) 21

V = π (25) 21

V = π (25 x 21)

V = π (525)

V = 525π

Step-by-step explanation:

Given the dimension of the bedroom yo be 2.25in by 2.5in

First we need to convert to foot

2.25in = 0.08333×2.25 = 0.1875feet

2.5in = 0.08333×2.5 = 0.2083feet

Area of the rectangular bedroom = length × width

Area of the rectangular bedroom = 0.1875×0.2083

Answer:

c = 20

Step-by-step explanation:

You have not really asked a question.

I will assume you are asking about the value of c.

The measure of angle 1 is 10 (assuming degrees!), so the measure of angle 2 is 80.  (Complementary angles have measures that sum to 90.)

The measure of angle 2 is also described as 4c, so 4c = 80.  That makes c = 20.
