Tatiana [17]4 years ago

Answer:

(a) 34.

(b) Yes.

Step-by-step explanation:

The first term is 3(1)^2 + 1 = 4 ( where k = 1).

The sum of 2 terms =  3(2)^2 + 2 = 14.

The sum of 3 terms = 3(3)^2 + 3 = 30.

The sum of 4 terms = 3(4)^2 + 4 = 52.

So the first 4 terms are 4, 10, 16 and 22 .     - increasing by 6.

The common difference is 6 so it is an arithmetic sequence.

The 6th term = a1 + d(n - 1)

= 4 + 6(6-1)

= 34.

Find H.C.F. and L.C.M. of x3-y3, x2-y2 and (x-y) ?​
maks197457 [2]

Answer:

1) x³-y³ = (x-y)(x²-xy+y²)

2)x²-y² =(x-y)(x+y)

3)x-y = (x-y)

hcf = (x-y)

lcm = (x-y)(x²-xy+y²)(x+y)= (x³-y³)(x+y)

If I Had A Hammer Hardware has sales of $5000 in its first month. Suppose sales were to increase by 4% every month. In how many
mixer [17]

After 14 months after the first month would the sales reach $9000

For given question,

A Hammer Hardware has sales of $5000 in its first month.

The sales were to increase by 4% every month.

We need to find the number of months after the first month would the sales reach $9000

Let the exponential function for sales is,

f(n)= a (1 + r)^{n}

where, n is the number of months

a is the sales of the first month

r is the rate of increment

So, a = $5000, r = 0.04, f(n) = $9000

Substitute values in above equation.

⇒ 9000 = 5000 × (1 + 0.04)^{n}

Solve above equation for n.

⇒ 1.8 = (1.04)^n

⇒ n = log_{1.04}^{(1.8)}

⇒ n = 14.9

⇒ n ≈ 15

Therefore, after 14 months after the first month would the sales reach $9000
