A Circle Has A Center At (-2,7). If A Point On The Circle Has Coordinates (3,-1) Then Which Of The Following
Answer 2

The length of radius is 7.81 unit.

What is Distance Formula?

The distance between two points P(a, b)a nd Q(c, d) is

D = √(c- a)² + (d- b)²

Given:

Center at (-2,7) if a point on the circle has coordinates (3,-1).

Using Distance Formula

D = √( 3-(-2))² + (1-7)²

D = √ (3 +2)² + (-6)²

D = √5² + 36

D = √25+36

D = √61

D= 7.81 unit

Hence, the length of radius is 7.81 unit.

The volume and base area of a rectangular cargo container is 720 cubic
meters and 120 square meters. Find the height of the container? *

A)86,400m3
B)400m3
C)4m
D)6m

Answers

Answer:

D, 6m

Step-by-step explanation:

Step one:

Given data

The volume and base area of a rectangular cargo container is 720 cubic

= 720m^3

The area of the cargo container is 120 m^2

Required

We want to find the height of the container

Step two

The expression  for the volume is given as

Volume= Area* height

so,

720= 120*h

divide both sides by 120

720/120= h

h= 6 m

The height is 6m

what linear equation in slope intercept from does this graph represent?​

Answers

Answer:

[tex]y = 16\frac{2}{3} x + 100[/tex] or [tex]y = \frac{50}{3} + 100[/tex]

Step-by-step explanation:

The equation of a line is [tex]y = mx + b[/tex], with [tex]m[/tex] being the slope and [tex]b[/tex] being the y-intercept.

We can see on the graph that the y-intercept, where the line crosses or touches the y-axis, is 100. So, our new equation is [tex]y = mx + 100[/tex].

Now we have to find the slope. Let's pick a point that's clearly on the graph. Perhaps (3, 150). And then we'll take the y-intercept point for convenience, (0, 100).

Then, we'll use [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1} }[/tex] to find the slope.

Let's substitute in our points.

[tex]\frac{150-100}{3-0}[/tex]

Simplify.

[tex]\frac{50}{3}[/tex]

Now, we can leave the slope like that or turn it into a mixed number. As a mixed number, your slope is [tex]16\frac{2}{3}[/tex].

We'll put that in our equation for a line and...bam!

[tex]y = 16\frac{2}{3} x + 100[/tex] or [tex]y = \frac{50}{3} + 100[/tex]

Why should we wear rubber gloves on our hands while working with electricity?​

Answers

Answer:

a simple answer would be that rubber doesnt conduct electricity, so by wearing it you are at a substantially lower risk of being insured by electricity.

If the measure of each base angle of an isosceles triangle is represented by x, then the vertex angles is represented by

Answers

Answer:

vertex angle = 180° - 2x

Step-by-step explanation:

Since, the measure of each base angle of an isosceles triangle is represented by x.

So, by interior angle sum postulate of a triangle, we have:

x + x + vertex angle = 180°

2x + vertex angle = 180°

vertex angle = 180° - 2x

So, the vertex angle is represented by (180° - 2x).

A machine wheel spins at a rate of 500 revolutions per minute. If the wheel has a diameter of 80 centimeters, what is the angular speed of the wheel, in radians per second? Round your answer to the nearest hundredth.

Answers

Answer: 3,140 radians per minute.

Step-by-step explanation:

We know that the wheel does 500 revolutions per minute.

This is called the frequency of the wheel, and this is written as:

f = 500 rev/min = 500 RPM

The angular speed (or Angular velocity) is written as

ω = 2*pi*f

And this quantity is in radians/unit of time.

where pi = 3.14

then:

ω = 2*3.14*500 (rev/min)*(rad/rev) = 3,140 rad/min

This means that the angular velocity  (or angular speed) is 3,140 radians per minute.

The required cumulative relative frequencies are 0.04, 0.44, 0.56, 0.80, and 1 respectively.  

What is the relative frequency of the data?

The relative frequency of the data is the ratio of the given frequency to the total frequency in the observation.

From the given data,

Relative frequency = given frequency / total frequency

Where total frequency = 0.04 + 0.4 + 0.12 + 0.24 + 0.2 = 1

Value     Relative frequency       Cumulative frequency

3                 0.04/1 = 0.04                  0.04    

4                 0.4/1 = 0.4                    0.04 + 0.4 = 0.44  

5                    0.12                           0.44 + 0.12 = 0.56

6                   0.24                           0.56 + 0.24 = 0.80  

7                     0.2                            0.80 + 0.2 = 1

Thus the required cumulative relative frequencies are 0.04, 0.44, 0.56, 0.80, and 1 respectively.

Suppose a friend tells you she paid a total of $20,500 for a car, and you’d like to know the car’s list price (the price before taxes) so that you can compare prices at various dealers. Find the list price of the car if your friend bought the car in:

Roswell, where the sales tax is 6.5%

Answers

Given :

Total amount paid for the car is, A = $20,500.

Sales tax is 6.5%.

To Find :

The list price i.e. price without tax.

Solution :

Let, list price is P.

P = A - 0.65A

P = A( 1 - 0.65 )

P = 20500×( 1 - 0.065 )

P = $19167.5

Therefore, the list price of car is $19167.5  .

Solve for x if y = 3 in the equation 2x + 3y = 12 *

Answers

Answer:

x = 3/2 or 1.5

Step-by-step explanation:

y = 3 in the equation 2x + 3y = 12

Substitute 3 in for y.

2x + 3(3) = 12

Multiply.

2x + 9 = 12

Subtract 9 from both sides.

2x + 9 - 9 = 12 - 9

2x = 3

Divide both sides by 2.

2x ÷ 2 = x

3 ÷ 2 = 3/2 or 1.5

x = 1.5

Answer:

X = 1.5

Step-by-step explanation:

So we know that Y = 3 and 3 x 3 = 9, then we need to get the difference of 9 to 12

12 - 9 = 3

we now know that x will equal 3, so 2 x 1.5 = 3, and 3 + 9 = 12

(Full equation)

2 x 1.5 + 3 x 3 = 12

A. -49
B. -7
C. 7
D. 49

Answers

Answer:

p=−12x2+8x+−492

is what I got

The value of p must be 7 for the expression (x - p)2 + 5 equivalent to the expression x2 – 14x + 54.

What are equivalent expressions?

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

It is given that the expression (x - p)2 + 5 equivalent to the expression x2 – 14x + 54

That is (x - p)^2 + 5 = x^2 – 14x + 54

Solving for p;

x^2 + p^2 + 5 - 2px =  x^2 – 14x + 54

Combine the like terms;

p^2 + 5 - 2px =– 14x + 54

p^2 - 2px + 14x - 49 = 0

If we put p = 7 then

49 - 14x + 14x - 49 = 0

Therefore, the value of p must be 7 for the expression (x - p)2 + 5 equivalent to the expression x2 – 14x + 54.

what is the rule for the reflection

Answers

Answer:

(x,y) ---> (-x,y)  2nd choice

Step-by-step explanation:

reflection: If points reflect across the y-axis, their y-coordinates remain unchanged but their x-coordinates change into their opposites.

The original figure ABCD is reflected on y-axis and we got the image A'B'C'D'. Therefore, option B is the correct answer.

What is the reflection on y-axis?

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

In the given graph, ABCD is the original figure and A'B'C'D' is the image.

Here, A(-2, 1)→A'(2, 1)

B(-4, 1)→B'(4, 1)

C(-4, 5)→C'(4, 5)

D(-2, 4)→D'(2, 4)

Here, the rule is (x, y)→(-x, y)

Therefore, option B is the correct answer.
