IM VERY SORRY if its wrong tho :(

Given:

The equation of given line is

[tex]y=3x-4[/tex]

A line is perpendicular to the given line and passes through the point (9,5).

To find:

The equation of the perpendicular line.

Solution:

We have,

[tex]y=3x-4[/tex]

On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get

[tex]m=3[/tex]

It means, the slope of the given line is 3.

The product of slopes of two perpendicular lines is -1.

[tex]m\times m_1=-1[/tex]

[tex]3\times m_1=-1[/tex]

[tex]m_1=-\dfrac{1}{3}[/tex]

Point slope form of a line is

[tex]y-y_1=m(x-x_1)[/tex]

Where, m is the slope.

The slope of perpendicular line is [tex]-\dfrac{1}{3}[/tex] and it passes through the point (9,5). So the equation of the line is

[tex]y-5=-\dfrac{1}{3}(x-9)[/tex]

[tex]y-5=-\dfrac{1}{3}(x)-\dfrac{1}{3}(-9)[/tex]

[tex]y-5=-\dfrac{1}{3}x+3[/tex]

Adding 5 on both sides, we get

[tex]y-5+5=-\dfrac{1}{3}x+3+5[/tex]

[tex]y=-\dfrac{1}{3}x+8[/tex]

Therefore, the equation of required line is [tex]y=-\dfrac{1}{3}x+8[/tex].

Answer:

2.0 km

Step-by-step explanation:

From the diagram attached,

cosθ = adjacent/Hypotenus

cos4° = x/2

make x the subject of the equation

x = 2cos4°

x = 2(0.998)

x = 1.995

x = 2.0 km. (to the nearest tenth)

Hence the horizontal distance is 2.0 km

Answer:

x ≈ 10.9

Step-by-step explanation:

Using the sine ratio in the right triangle

sin40° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{x}[/tex] ( multiply both sides by x )

x × sin40° = 7 ( divide both sides by sin40° )

x = [tex]\frac{7}{sin40}[/tex] ≈ 10.9 ( to the nearest tenth )

Answer:

x = 10

Step-by-step explanation:

Angles are congruent because they are vertical angles:

5x + 6 = x + 46

5x - x = 46 - 6

4x = 40

x = 10

Answer:

Step-by-step explanation:

Before the increase it was 100%

So 20+100=120

156/120*100=130$

Don’t do it like 20/100 *156 and then minus it from 156 because you will get a wrong answer

(This was answered by another person on a another question.)

Answer:

130

Step-by-step explanation:

x * 1.2 = 156

x = 156/1.2

x = 130

Answer:

3.45677

Step-by-step explanation:

The number 3 represents the speed of the pet turtle. And the number 12 represents the distance already covered at t = 0.

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

A pet turtle strolls towards his food dish at a consistent speed in an orderly fashion. His Distance in inches y from his food dish after X seconds is given by y = 3x + 12.

In the equation, the number 3 represents the speed of the pet turtle. And the number 12 represents the distance already covered at t = 0.

Answer:

Angle k is 34.5 degrees

Step-by-step explanation:

a circle makes 360 degrees total.  okay so u have to consider the angles given. m arc go= 127

m<0 = 54.5

54.5 times 2 = 109

109 is arc gk

109 + 127+ 55= 291

360-291=69= arc OU

69 divided by 2 is 34.5

Angle k is 34.5 degrees

Answer: 1. A) 2/5 B) X= -5 Y= 2

2. A) -3/2 B) X= 2 Y= 3

3. A) -2/3 B) X= -3 Y= -2

Step-by-step explanation: A) Look where the line intersects perfectly through a corner of one of the boxes, find the next one closes to that count how many it goes up and how many across. Rise/Run so the amount it goes up goes on the top of the fraction and the amount across on the bottom of the fraction.

B) This is where the line intersects the X and Y axis

Given:

The sequence can be generated by

[tex]a_n=4a_{(n - 1)}[/tex]

Where [tex]a_1= 6[/tex] and [tex]n[/tex] is a whole number greater than 1.

To find:

The first four terms of the given sequence.

Solution:

We have,

[tex]a_n=4a_{(n - 1)}[/tex]          ...(i)

It is given that [tex]a_1= 6[/tex]. So, for [tex]n=2[/tex], we get

[tex]a_2=4a_{(2 - 1)}[/tex]

[tex]a_2=4a_1[/tex]

[tex]a_2=4(6)[/tex]

[tex]a_2=24[/tex]

Putting [tex]n=3[/tex] in (i), we get

[tex]a_3=4a_{(3- 1)}[/tex]

[tex]a_3=4a_2[/tex]

[tex]a_3=4(24)[/tex]

[tex]a_3=96[/tex]

Putting [tex]n=4[/tex] in (i), we get

[tex]a_4=4a_{(4- 1)}[/tex]

[tex]a_4=4a_3[/tex]

[tex]a_4=4(96)[/tex]

[tex]a_4=384[/tex]

The first four terms of the given sequence are 6, 24, 96,384.

Therefore, the correct option is C.

Answer:

it is going to be B. 10 m/s

The speed of the car on the highway will be 30 m/s

The rate at which velocity changes with time, in terms of both speed and direction.

Given that, a car is driving 18 meters per second. It then merges on to a highway and accelerates at a rate of 6 meters per second for 2.0 seconds.

Using first equation of motion,

v = u + at where, v is final velocity, u is initial velocity, a is acceleration and t is time,

v = 18 + 6*2

v = 18 + 12

v = 30

Hence, speed of the car on the highway will be 30 m/s

Answer:

16

Step-by-step explanation:

Total surface area of a cone T1 = πr(r+l)

If the radius and the slant height of this right circular cone are each multiplied by 4, the new surface area will be expressed as;

T1 = π4r(4r+4l)

T2 = 16πr(r+l)

Taking the ratio of both total area

T1/T2 = πr(r+l)/16πr(r+l)

T1/T2 = 1/16

16T1 = T2

T2 = 16 T1

Hence the total surface area is multiplied by a factor of 16

Answer:

1st pic) 17.8

2nd pic) 16.8

3rd pic) 9.1

4th pic) 13.5

Step-by-step explanation:

1st pic: [tex]cos = \frac{adjacent}{hypothenuse}[/tex]

(write equation) Cos 27 (cos 27 = 0.89) = [tex]\frac{x}{20}[/tex]

(new equation) 0. 89 = [tex]\frac{x}{20}[/tex]

(multiply 20 on both sides) 0.89 x 20 = [tex]\frac{x}{20}[/tex] x 20

(solve) 17.8 = x

2nd pic: [tex]tan = \frac{adjacentx}{hypothenuse}[/tex]

(write equation) tan 40 (tan 40 = 0.84) = [tex]\frac{32}{x}[/tex]

(new equation) 0.84 =  [tex]\frac{32}{x}[/tex]

(multiply 32 on both sides) 0.84 x 20 =  [tex]\frac{32}{x}[/tex] x 20

(solve) 16.8 = x

3rd pic: [tex]cos = \frac{adjacent}{hypothenuse}[/tex]

(write equation) cos 55 (cos 55 = 0.57) = [tex]\frac{16}{x}[/tex]

(new equation) 0.57 = [tex]\frac{16}{x}[/tex]

(multiply 16 on both sides) 0.57 x 16 = [tex]\frac{16}{x}[/tex] x 16

(solve) 9.1 = x

4th pic: [tex]tan = \frac{adjacentx}{hypothenuse}[/tex]

(write eqaution) tan 42 (tan 42 = 0.90) = [tex]\frac{x}{15}[/tex]

(new equation) 0.90 = [tex]\frac{x}{15}[/tex]

(multiply 15 on both sides) 0.90 x 15 = [tex]\frac{x}{15}[/tex] x 15

(solve) 13.5 = x
