Answer:

F(x)= 5+3(n-1)

Step-by-step explanation:

5 represents term 1. +3 is demonstrating what you do in the pattern for every resulting number. you multiply by (n-1) because 5+3 already demonstrates the next term, so you subtract the term number by 1

Answer:

2+3n

Step-by-step explanation:

This question is based on a topic called sequence and series,under which we have the arithmetic progression

The formula for arithmetic progression is a+(n-1)d

In which a is the first number,n is the nth term and d is the difference

Back to the question

a=5,n=it's not given,d=3

Using the general formula

a+(n-1)d

5+(n-1)3

Open the bracket first

5+3n-3

Collect like terms

5-3+3n

2+3n

The answer is 2+3n

And it can be solved further only if we are given the value of n...the question even stated that we should solve in terms of n

Therefore the answer is 2+3n

Pada hari kantin sebanyak 800 naskah kupon telah dijual,harga senaskah kupon masing masing rm 30 dan rm 50 .jumlah wang diperole
solniwko [45]

Answer:

Step-by-step explanation:

On the day of the canteen, 800 coupons were sold, the price of each coupon was RM 30 and RM 50 respectively. The amount of money earned from the sale of coupons was RM30000. How many copies of RM30 and RM50 coupons were sold?

Let:

RM 30 = x

RM 50 = y

x + y = 800 - - - (1)

30x + 50y = 30000 - - - (2)

From (1)

x = 800 - y

Put x = 800 - y in (2)

30(800 - y) + 50y = 30000

24000 - 30y + 50y = 30000

24000 + 20y = 30000

20y = 30000 - 24000

20y = 6000

y =

Answer:

Option (B). Perimeter of the quadrilateral ABCD= 14.6 units

Step-by-step explanation:

From the figure attached,

Coordinates of the vertices are A(3, 5), B(1, 3), C(3, -1), D(5, 3).

Length of AB = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

                      = \sqrt{(3-1)^2+(5-3)^2}

                      = \sqrt{8}

                      = 2.83 units

Length of AD = \sqrt{(3-5)^2+(5-3)^2}

                      = \sqrt{8}

                      = 2.83 units

Length of BC = \sqrt{(1-3)^2+(3+1)^2}

                      = \sqrt{20}

                      = 4.47 units

Length of DC = \sqrt{(5-3)^2+(3+1)^2}

                       = \sqrt{20}

                       = 4.47 units

Perimeter of the quadrilateral = AB + AD + DC + BC

                                                 = 2.83 + 2.83 + 4.47 + 4.47

                                                = 14.6 units  

Option (B) is the answer.

The geometry of the hybrid orbitals about a central atom with sp3d hybridization is:________
Lyrx [107]

For sp3d hybridized central atoms, the only possible molecular geometry is trigonal bipyramidal.

Hybridisation (or hybridization) is a process of mathematically combining two or more atomic orbitals from the same atom to form an entirely new orbital different from its components and hence being called as a hybrid orbital.

In this case, if all the bonds are in place, the shape is also trigonal bipyramidal.

In chemistry, a trigonal bipyramid formation is a molecular geometry with one atom at the center and 5 more atoms at the corners of a triangular bipyramid.

Bond angle(s): 90°, 120°

Coordination number: 5

Point group: D3h
