Write the standard equation of the circle with center (6,-1) and radius 7.4.

Write The Standard Equation Of The Circle With Center (6,-1) And Radius 7.4.

Answers

Answer 1

Answer:

C.

Step-by-step explanation:

You do the opposite to the numbers when plugging them into the equation and what they equal will be the radius squared.

6 goes to -6 and -1 turns to 1.

7.4 squared= 54.76

Answer 2

Standard equation of the circle with center (6,-1) and radius 7.4 is [tex](x-6)^{2}+(y+1)^{2} = 54.76[/tex]

Option (C) is correct

What is a circle?

"A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape."

What is center of a circle?

"The center of a circle is the point which is equidistant from all points on the circle."

What is the radius of circle?

"The constant distance between the center and any point of the circle is called its radius."

We have,

Center (h, k) = (6,-1)

Radius r = 7.4

We know,

Standard equation of the circle is [tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

Substitute the values of h, k, r in standard equation of circle

[tex](x-6)^{2}+(y+1)^{2}=(7.4)^{2}[/tex]

⇒[tex](x-6)^{2}+(y+1)^{2} = 54.76[/tex]

Hence, Standard equation of the circle with center (6,-1) and radius 7.4 is [tex](x-6)^{2}+(y+1)^{2} =54.76[/tex]

Option (C) is correct

How do you find the equations of the vertical and horizontal asymptotes for a graph when you only have the graph and no function?

Answers

Answer:

See below for answer and explanations (as well as an attached graph)

Step-by-step explanation:

Pay attention to the behavior of the asymptotes. If the asymptotes are approaching a certain x-value or y-value, then that value is undefined for the function.

Take for example [tex]y=\frac{1}{x}[/tex]:

As x approaches ∞ and -∞, then y approaches 0, which is our horizontal asymptoteAs y approaches ∞ and -∞, then x approaches 0, which is our vertical asymptote

A cuboid has 3 different sized faces. The areas of 2 of the faces are 84cm2and 56cm2. The volume of the cuboid is 672cm3. Find the length, width and height of the cuboid and the area of the third face.

Answers

Answer:

Length: 12 cm

Width: 8 cm

Height; 7 cm

Step-by-step explanation:

We are told that the areas of 2 of the faces are 84cm² and 56cm².

Now, the side faces are 4 in total with 2 each having same areas.

Thus, it means they would have the same height.

Let's find the highest common factor between 84cm² and 56cm².

The highest number that can be divide each equally is 7.

Thus;

12 × 7 = 84 cm²

8 × 7 = 56 cm²

This means, the bottom part will measure 12 cm by 8 cm.

Thus, the complete measurement is;

Length: 12 cm

Width: 8 cm

Height; 7 cm

Let's check if it will give us a Volume equal to that given.

Thus;

Volume = 12 × 8 × 7 = 672 cm²

This is same as that given and so our dimensions are correct.

Things to remember:

Sin = Opposite / Hypotenuse

Cos = Adjacent / Hypotenuse

Tan = Opposite / Adjacent

Whatever 2 terms you have in your equation are the ones you will use to determine Sin/Cos/Tan. For example, in question 21, the “X” was adjacent to your given angle (74°). The hypotenuse was 12, so you would use Cos since your two terms are Adjacent / Hypotenuse.

Also remember, the hypotenuse is the side opposite of the 90° angle.

The opposite side is the side opposite of the angle given (Not 90°).


The adjacent side is the side adjacent to the angle given (Also not 90°).

Step-by-step explanation:

Note that the denominators in the expression are perfect squares:

[tex] {x}^{2} - 5xy + 6 {y}^{2} = (x - 2y)(x - 3y)[/tex]

[tex] {x}^{2} - 4xy + 3 {y}^{2} = (x - y)(x - 3y)[/tex]

[tex] {x}^{2} - 3xy + 2 {y}^{2} = (x - y)(x - 2y)[/tex]

We can then write the given expression as

[tex] \frac{1}{ {x}^{2} - 5xy + 6 {y}^{2} } + \frac{a}{{x}^{2} - 4xy + 3{y}^{2} } + \frac{1}{{x}^{2} - 3xy + 2{y}^{2}}[/tex]

[tex] = \frac{1}{(x - 2y)(x - 3y)} + \frac{a}{(x - y)(x - 3y)} + \frac{1}{(x - y)(x - 2y)}[/tex]

Step-by-step explanation:

Vertex Form of a Vertical Parabola:

[tex]y=a(x-h)^2+k[/tex]

Vertex -> [tex](h,k)[/tex]

Axis of Symmetry -> [tex]x=h[/tex]

Vertical Scale Factor -> [tex]a[/tex]

To turn [tex]f(x)=x^2+4x-5[/tex] into vertex form, we need to complete the square on the right sideTherefore, if [tex]f(x)=0[/tex], then [tex]0+9=x^2+4x-5+9[/tex] completes the square on the right side This becomes [tex]9=(x+2)^2[/tex]This means that our function in vertex form is [tex]f(x)=(x+2)^2-9[/tex]

Therefore, the vertex of the graph is [tex](h,k)=(-2,-9)[/tex].

The coordinates of the vertex of the graph is (-2, -9).

This gives A=11²π, which by solving the square gives A=121π.

From there, you would solve with a calculator by typing 121×π, giving a final area of 380.132711084.

From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 12^{\circ} ∘ . At some later time, the crew measures the angle of elevation from point BB to be 2^{\circ} ∘ . Find the distance from point AA to point BB. Round your answer to the nearest foot if necessary.

Answer:

Step-by-step explanation:

Using the solution diagram attached, the vertical height, h of the lighthouse ;

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 2 = h / 804

h = tan 2 * 804

h = 28.076 feets

Using h, we can obtain the distance CB :

Tan θ = opposite / Adjacent

Tan 2 = 28.076 / CB

CB = 28.076 / Tan 12°

CB = 132.08860 feets

Distance between A and B

In the summer term sal wlks to school starting soon after 7 am when the hour hand is at angle of 110 degrees to the minute hand. She arrives at school before 8 am when

Answers

Answer:

She walked for 46 minutes

Step-by-step explanation:

Given

When she leaves home

[tex]h = 7am[/tex]

[tex]\theta_1 = 110^o[/tex]

When she arrives at school

[tex]H = 8am[/tex]

[tex]\theta_2 = 110^o[/tex]

Required

Time to walk to school

First, we convert [tex]\theta_1 = 110^o[/tex] to minutes:

[tex]\theta_1 = \frac{110}{6}[/tex]

[tex]\theta_1 = 18.33[/tex]

[tex]\theta_1 = 18[/tex] --- approximated

From the question, we understand that she left home past 7.

This means that the difference between the hour hand (at 7) and the minutes hand is 18 minutes.

Also, the minute hand is between 0 and 30 minutes

Subtract 18 minutes from 30 minutes;

[tex]Mins = 30-18=12[/tex]

She left home at 7:12am

Similarly;

[tex]\theta_2 = \theta_1 = 18\ mins[/tex]

From the question, we understand that she arrived before 8.

This means that the difference between the hour hand (at 8) and the minutes hand is 18 minutes

Also, the minute hand is between 30 and 60 minutes mark.

At the 8hour hand, the minutes is 40

Add 18 minutes from 40 minutes;

[tex]Mins = 40 + 18 = 58[/tex]

She arrived at 7:58am

The difference (d) is:

[tex]d =7:58am - 7:12am[/tex]

[tex]d =46[/tex]
