The third term in a sequence is 25. The fifth term is 225. What are the possible values of the 4th term of the sequence if it is arithmetic? If it is geometric?

Answers

Answer 1

Answer:

Answer:

if it is arithmetic, ach item us increase linearly. The general term is - 175+100(n-1)

where n is the number of term.

the 4th term is 125

if it is geometic, each item us increased exponetially. T he general term is 25/9 x 3^(n-1)

where n is the number of term

the 4th term is 75

The perimeter of a sheet of paper is 38cm. If the width is 8 cm what is the length of the paper?

Answers

15. (2•l)+(2•w)=38.
(2•l)+8=38.
Subtract 8 from both sides which leaves (2•l)=30.
Divide by 2 from both sides and that leaves 15.

The hcf of two numbers is 7and their lcm is 210. If one of these numbers is 35,find the other

Answers

Answer:

Step-by-step explanation:

The relation between HCF and LCM is that the product of 2 numbers is equal to the product of the HCF of two numbers and the product of LCM of the two numbers.

(7)(210) = (35)(x)

1470 = 35x

x = 42

so F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40

1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph

Help me please. I don't understand this section

Answers

What you do is that you use your algebraic magic to find your c value. First, you will divide both sides by 5. Now you have 2b= the square root of c +2. Now subtract 2 from both sides and you will have 2b-2= the square root of c. To undo the square root of c, you will need to square it, so square both sides and you have your answer. Good luck!

if k is a constant, determine and state the value of kids such that the polynomial k^2x^3-6kx+9 divisible by x-1

Answers

By the polynomial remainder theorem, $k^2x^3-6kx+9$ will be divisible by $x-1$ if the value of the polynomial at $x=1$ is 0.

$k^2(1)^3-6k(1)+9=k^2-6k+9=(k-3)^2=0$

which occurs for $k=3$ .
