Consider the following number pattern: -7; 0; 9; 20; ... Show that the general term of this quadratic number pattern is given by T₁ = n² +4n-12. 2.1​

Answers

Hence the general term of the given quadratic number pattern is given by Tn = n²+4n-12 is verified.

The number pattern = -7,0,9,20

What is the formula for quadratic equation?

Let the general term of the given quadratic number pattern is given by

Tn = an²+bn + c

When T = -7; n = 1

⇒ -7 = a(1)² +b (1) +6

⇒ a + b + c=-7 -----------1

At n=2, T₂ = 0

⇒ 0 = a(2)²+b(2)+c

4a+2b+c=0 ---------------2

At n=3, T = 9

⇒ 9 = a(3)²+b(3) +c

⇒ 9a+3b+c= 9 ---------3

Subtracting 3 from 2

⇒-5a-b = -9 --------4

Subtracting 2 from 1

-3a-b = -7  -----------5

Subtracting 5 from 4

2a = 2

⇒ a=1

Using eq 5, we get

-3(1) - b = -7

-b = -7 + 3

b = 4

From eq 1, a + b + c=-7 we get the value of c,

1 + 4 + c = -7

c = -7 -5

c = -12

substitute the values of a, b, and c in Tn = an²+bn + c

Tn = n² + 4n - 12

Hence the general term of the given quadratic number pattern is given by Tn = n²+4n-12.

parallelogram has sides of lengths 35 inches and 75 inches. One angle has measure of140°. Find the length of each diagonal.

Answers

The length of diagonal of a parallelogram is 2546 inches.

What is a parallelogram?

A quadrilateral with equal pairs of opposing sides and angles is referred to as a parallelogram. It has a pair of opposing sides that are parallel to one another. The inner angles are supplementary in nature, meaning that the sum of them equals 180 degrees. A parallelogram's diagonals are bisected by one another, or divided into two equal portions. A parallelogram's internal angles add up to 360 degrees.

The diagonals of parallelogram are given by:

x = √(a^2 + b^2 – 2ab cos A) = √(a^2 + b^2 + 2ab cos B)

Given the two sides are 35 and 75 inches.

We also know that the adjacent angles of parallelogram are supplementary:

∠A + ∠B = 180

140 + ∠B = 180

∠B = 40

Substitute the value of sides and angle in the equation:

x = √(a^2 + b^2 – 2ab cos A) = √(a^2 + b^2 + 2ab cos B)

x = √((35)^2 + (72)^2 + 2(35)(72) cos 140)

x = 1225 + 5184 + (5040)(-0.766)

x = 1225 + 5184 - 3860

x = 2546 inches

Hence, the length of diagonal is 2546 inches.

I need help on part b

Answers

Answer:

a) The pattern 6 has 26 sticks,b) The pattern number n has 4n + 2 sticks.

--------------------------

If we put the number of sticks in a sequence we get:

6, 10, 14, ...

As we see the difference of the terms is common and is 4, and the first term is 6. It is therefore an arithmetic progression with:

a = 6 and d = 4

Use the nth term equation:

a(n) = a + (n - 1)d

Part a)

Substitute n = 6 to find the number of sticks of the 6th term:

a(6) = 6 + (6 - 1)*4 = 6 + 5*4 = 6 + 20 = 26

Part b)

Find the nth term:

a(n) = 6 + (n - 1)*4 = 6 + 4n - 4 = 4n + 2

In a lab experiment, 40 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 23 hours. How long would it be, to the nearest tenth of an hour, until there are 82 bacteria present?

Answers

The time needed until there are 82 bacteria is given as follows:

23.8 hours.

How to use the exponential function to find the time?

An exponential function is defined as follows:

[tex]y = a(b)^{\frac{x}{n}}[/tex]

In which:

a is the initial value.b is the rate of change.n is the time needed for the rate of change.

The parameters for this problem are given as follows:

a = 40, b = 2, n = 23.

Hence the function is:

[tex]y = 40(2)^{\frac{x}{23}}[/tex]

There will be 82 bacteria at a time x when y = 82, hence:

[tex]82 = 40(2)^{\frac{x}{23}}[/tex]

[tex](2)^{\frac{x}{23}} = 2.05[/tex]

Applying the logarithm of base 2 to each side, we have that:

x/23 = log2(2.05)

x = 23 x log2(2.05)

x = 23.8 hours.

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that two triangles in the map below are similar.

We can write -

{ 1 } -

sin (A) = a/c

a = c sin(A)

a = 12 sin(40°)

a = 12 x 0.65

a = 7.8

{ 2 } -

cos (A) = b/c

b = c cos(A)

b = c cos(40°)

b = 12 x 0.77

b = 9.24

{ 3 } -

tan (B) = b/a

tan (B) = 9.24/7.8

tan (B) = 1.19

5 -foot shadow. If Jane is 5’9" tall and is

standing nearby, find the length of her


shadow

Answers

The length of Jane's shadow is approximately 2.85 feet

To find the length of Jane's shadow, we can use the principle of similar triangles.

The ratio of the shadow length to the object height is the same for both King Neptune and Jane, then we can set up a proportion:

(shadow length of King Neptune) / (height of King Neptune) = (shadow length of Jane) / (height of Jane)

Given that King Neptune's shadow is 3 13 5 feet and the statue is 34 feet tall.

By substituting these values into the proportion:

(3 13 5 feet) / (34 feet) = (shadow length of Jane) / (5' 9")

To find the shadow length of Jane, we can cross-multiply and solve for the shadow length:

(3 13 5 feet) * (5' 9") = (shadow length of Jane) * (34 feet)

Converting Jane's height into feet: 5'9" = 5*12 +9 = 69 inches = 5.75 ft

(3 13 5 feet) * (5.75 ft) = (shadow length of Jane) * (34 feet)

shadow length of Jane = (313.5*5.75) / 34 = 2.85 ft

So, The length of Jane's shadow is approximately 2.85 feet.

Consumers always want to pay the least price possible for a good or service. The option the sisters would choose is the cheaper option.

Cost of the watch if the coupon is used first = price of the watch x (1 - coupon)

If Lilyana runs a cake decorating business for which 10% of her orders come over telephone , then probability that it takes fewer than 5 orders for Lilyana to get her first telephone is 0.3439  .

The geometric distribution is used to calculate the required probability ,

In this case, the success is a telephone order, and

the failure is an order placed in some other way.

Let probability of success is ⇒ p , and

let the number of orders needed to get the first telephone order be = x . Then, X follows a geometric distribution with parameter p, so we have:

Probability of P(X = k) is = (1-p)^(k-1) × p ;

where k is the number of orders needed.

the probability of success (p) is  = 10% = 0.1

we have to find the probability that it takes fewer than 5 orders for Lilyana to get her first telephone order of the month.

that means : P(X<5) = P(X=1) + P(X=2) + P(X=3) + P(X=4)

Substituting the values of p = 0.1 ,

we get ;

= (1-0.1)⁰ × 0.1 + (1-0.1)¹ × 0.1 + (1-0.1)² × 0.1 + (1-0.1)³ × 0.1

Simplifying further ,

we get ;

Answers

The table which matches the equation and includes only viable solutions is the third table.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side

Given that equation is,

c = 3.5b

Here b is the number of loaves of bread and c is the total cost of the bread.

All the table values matches the equation when we substitute the value of b and c in the equation.

But number of loaves of bread cannot be fractions or negative numbers.

So the most viable solution is the third table consisting of values of b as  0, 3, 6, 9 and corresponding value of c as 0, 10.5, 21, 31.5.

Hence the 2-column table with the first column labeled loaves (b) with entries 0, 3, 6, 9 and the second column labeled cost (c) with entries 0, 10.5, 21, 31.5 is the correct one.

The side length of a square is 5x - 7. Find x if the perimeter is 125.

Answers

The numerical value of x in the expression 5x - 7 is 7.65.

What is the numerical value of x?

A square is simply a 2-dimentional plane figure with four equal sides and four right (90°) angles.

The perimeter of the square is the sum of the length of all four sides of the square.

P = 4l

Given the data in the question

Side length of square l = 5x - 7Perimeter P = 125Value of x = ?

To find the value of x, plug the given values into the above equation and simplify.

P = 4l

125 = 4( 5x - 7 )

125 = 20x - 28

125 + 28 = 20x

153 = 20x

20x = 153

x = 153/20

x = 7.65

Therefore, the value of x is 7.65.

4 painters that have completed 12 rooms in 8 hours. assuming they are working at the same efficiency, how many hours does it take 7 painters to paint 21 rooms?

Answers

Answer:  We can use the concept of rates to solve this problem.

A rate is a ratio of the amount of work done to the amount of time it takes to do the work. We can find the rate of work for the 4 painters by dividing the number of rooms they painted by the number of hours it took them:

Rate = Rooms painted / Hours

Rate = 12 rooms / 8 hours = 1.5 rooms per hour

Now we can use this rate to find out how long it will take 7 painters to paint 21 rooms. To do this, we'll use the formula:

Time = Rooms / Rate

Time = 21 rooms / 1.5 rooms per hour = 14 hours

So it would take 7 painters working at the same efficiency as the 4 painters 14 hours to paint 21 rooms.
