Write an<br> explicit formula for<br> then<br> th<br> an.<br> term of the sequence 45, 15,5. ....
7nadin3 [17]

Answer:

The sequence above is a geometric sequence

For an nth in a geometric sequence

u(n) = a {r}^{n - 1}

where n is the number of terms

a is the first term

r is the common ratio

From the question

a = 45

r = 15 / 45

The explicit formula for the sequence is

U(n) = 45(1/3)^n-1

Hope this helps you

Factor the expression<br> 7x^2 + 50x + 7<br> (Type your answer in factored form.)
alina1380 [7]

Answer: (7x + 1)(x + 7)

Step-by-step explanation:

$$Factor the following:$$7 x^{2}+50 x+7$$Factor the quadratic $7 x^{2}+50 x+7$. The coefficient of $x^{2}$ is 7 and the constant term is 7. The product of 7 and 7 is 49 . The factors of 49 which sum to 50 are 1 and 49. So:\\\\ $7 x^{2}+50 x+7\\=7 x^{2}+49 x+x+7\\=7(7 x+1)+x(7 x+1)$ \\\\Factor $7 x+1$ from $7(7 x+1)+x(7 x+1)$ :$$\\\\Answer:(7 x+1)(x+7)$$
