T3 - 6=6

T3=12

then T2-T1=4

6-T1=4

T1=2

T4-T3=8

T4-12=8

T4=20

Therefore terms= 2,6,12,20

1st difference= 4,6,8

2nd difference= 2,2,....

2a=2

a=1

3a+b=4

3(1) + b=4

b= 1

a+b+c= 2

c= 2-1- 1= 0

giving Tn= n^2 + n

T12 = 12^2 + 12 = 156

In this question, to find the total height first, we must also take into consideration the acceleration due to gravity as well. To find the distance by which acceleration due to gravity pulls the ball down must know the Initial velocity.

In the answer key, it says that gravity changes the ball's height by a distance of -5t^2

Is initial velocity in this question 0 or 14m/s? Because if it is 14, then gravity should change the balls position by -(14+5t^2), not -5t^2, because if I remember correctly, the formula for finding distance is vt(initial velocity)+(1/2)at^2 ,and not just (1/2)at^2

Answer:

The length scale factor = \(\frac{24}{6} = 4\)

The area scale factor = \(4^2 = 16\)

\[\text{Larger area} = 16 \times \text{smaller area}\]

\[50.3 \times 16 = 804.8\]

The area of the large clock face is approximately 804.8 cm2.

Step-by-step explanation:

The length scale factor = \(\frac{24}{6} = 4\)

The area scale factor = \(4^2 = 16\)

\[\text{Larger area} = 16 \times \text{smaller area}\]

\[50.3 \times 16 = 804.8\]

The area of the large clock face is approximately 804.8 cm2.

Answer:

a) the linear scale factor = 5/3

b) the volume scale factor = 125/27

c) 70.2 cm³

Step-by-step explanation:

r₁ = 15 cm, r₂ = 25 cm

r₂/r₁ = 25/15 = 5/3

They are similar, so h₂/h₁ = 5/3

a) the linear scale factor = 5/3

b) the volume scale factor = (5/3)³ = 125/27

c) V₂/V₁ = 125/27

Given V₂ = 325 cm³, V₁ = 325*27/125 = 70.2 cm³

Answer:

y-5=3/4(x-6)

Step-by-step explanation:

The picture you posted is a bit unclear and difficult to look at, but that's alright.

This is a simple question if you understand that the point slope for equation is: y-y1 = m(x-x1).

m is the slope and (x1,y1) is a point on the graph.

So, if you input the point (6,5) on the graph, it works.

You can double check with the other equations to see that they are all wrong!

Have an amazing day!!

PLEASE RATE!!

Hi! I hope you're enjoying your day!

Please remember that the coefficient is the number before a variable.

Also, if we have no coefficient, then we have a coefficient of 1.

Here we have

x^3 (no coefficient)

the power is after the ^ symbol or written above a number (like [tex]\bold{t^h}[/tex]) where h is the power of t

Hence, the answer is

[tex]\boxed{\boxed{\bold{3}}}[/tex]

Hope everything is clear.

Step-by-step explanation:

mx + b = y

2x + 96 = y

-3x + 80 = z

What we want is y to be twice z, or y = 2z

If we're going to make 2z, then that means its equation needs to be doubled as well:

2x + 96 = 2(-3x + 80)

2x + 96 = -6x + 160

8x = 64

x = 8

Now to check our answer:

2 * 8 + 96

16 + 96 = 112

-3 * 8 + 80

-24 + 80 = 56

56 * 2 = 112

Answer:

Tom paints the fence in 24 hours and Bill paints the fence in 12

Step-by-step explanation:

T = 1 fence / x hours

B = 1 fence / x - 12 hours

B + T = 1 fence / 8 hours

( 1 fence / x - 12 hours ) + ( 1 fence / x hours ) = 1 fence / 8 hours

( 1 / x - 12 ) + ( 1 / x ) = 1 / 8

multiply through all the denominators to get:

8x + 8 (x - 12 ) = x( x - 12 )

8x + 8x - 96 = x^2 - 12x

combine like terms to get:

x^2 - 28x + 96 = 0

factor to get:

( x - 4 ) ( x - 24 ) = 0

x = 4, 24

4 won't work, because that would mean Bill would take a negative amount of time to paint the fence by himself, so that means

Tom paints the fence in 24 hours and Bill paints the fence in 12

Given:

The difference between 7 and the sum of 1.0006 and 4.06.

To find:

The mathematical expression for given statement and it value.

Solution:

Sum of 1.0006 and 4.06 = [tex](1.0006+4.06)[/tex]

The expression for the difference between 7 and the sum of 1.0006 and 4.06 is

[tex]7-(1.0006+4.06)[/tex]

On simplification, we get

[tex]7-(1.0006+4.06)=7-5.0606[/tex]

[tex]7-(1.0006+4.06)=1.9394[/tex]

Therefore, the difference between 7 and the sum of 1.0006 and 4.06 is 1.9394.

The school is about 14.95 meters tall, and the mirror is 8.25 meters from the school.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let Ф represent the angle Elijah makes with the ground, hence:

tanФ = 1.45/0.8

Ф = 61.11°

The angle of elevation to the building is 61.11°. Let h represent the height of the building.

tan(61.11°) = h/8.25

h = 14.95

The school is about 14.95 meters tall, and the mirror is 8.25 meters from the school.

Answer:

5,90

Step-by-step explanation:

got it correct :)

The second solution for the system of equations is (5, 90).

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Given the system of equations,

y - 10 = 11x + x² and

y - 12x = 30

Consider second equation.

y - 12x = 30

⇒ y = 30 + 12x

Substitute y = 30 + 12x in the equation y - 10 = 11x + x², we get,

(30 + 12x) - 10 = 11x + x²

12x + 20 = 11x + x²

12x - 11x - x² + 20 = 0

-x² + x + 20 = 0

x² - x - 20 = 0

Discriminant = [tex]\sqrt{(-1)^{2} -(4*1*-20)}[/tex] = √(1 + 80) = √81 = ±9

x = (1 + 9)/2 and x = (1 - 9) / 2

x = 5 and x = -4

The solution x = -4 and y = -18 is given.

Other solution is,

x = 5

y = 30 + 12x = 30 + 60 = 90

Hence the second solution is (5, 90).
