Answer: an = a1 + d(n-1) or an = 24 + 6(n-1)

Step-by-step explanation:

Answer:

See explanations below

Step-by-step explanation:

Volume of the sphere is expressed as;

V = 4/3πr³

r is the radius

V = 4/3 * 3.14 * 3³

V = 4/3  * 3.14 * 27

V = 4 * 3.14 * 9

V = 113.04cube units

For the secind sphere;

diameter = 12

radius = 12/2 = 6

V = 4/3πr³

r is the radius

V = 4/3 * 3.14 * 6³

V = 4/3  * 3.14 * 216

V = 4 * 3.14 * 72

V = 904.32cube units

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:

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

Delta math told me lol

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:

It would take Beth twelve minutes to wash the car herself

Step-by-step explanation:

If they do it together in 6 minutes.

& Katy can do it in 18 minutes alone

Then 18 - x = 6

replace x for twelve

18 - twelve = 6

Ans: twelve

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:

Pyramid A had a lateral area of 100 and Pyramid B has a Lateral area of 225

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:

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

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:

Step-by-step explanation:

x + 6 not hard

Answer:

Is C friend

Step-by-step explanation:

The expression that represents 6 more than x is x + 6. You can also rewrite this as 6 + x, but there is no need.

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.
