Aya = a1 + (n - 1)d

Alenkasestr [34]

Answer:

The 26th term of an arithmetic sequence is:

$a_{26}=67$

Hence, option A is true.

Step-by-step explanation:

Given

a₁ = -33

d = 4

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

substituting a₁ = -33 and d = 4 in the nth term of the sequence

$a_n=-33+\left(n-1\right)4$

$\:a_n=-33+4n-4$

$a_n=4n-37$

Thus, the nth term of the sequence is:

$a_n=4n-37$

now substituting n = 26 in the nth term to determine the 26th term of the sequence

$a_n=4n-37$

$a_{26}=4\left(26\right)-37$

$a_{26}=104-37$

$a_{26}=67$

Therefore, the 26th term of an arithmetic sequence is:

$a_{26}=67$

Hence, option A is true.

The index number representing the price level changes from 109 to 113 in one year. The inflation rate during the year is _____ p

Dima020 [189]

First, get the difference between the price level changes.

$113-109=4$

Then, divide it by the initial price level, which is 109.

$\frac{4}{109}=0.0367$

Multiply by 100 to get its percent.

$0.0367\times100=3.67$

Thefore, the inflation rate during the year is 3.67 percent.

Consider the quadratic equation below. 4x^2-5=3x+4 Determine the correct set-up for solving the equation using the quadratic for

lidiya [134]

$4x^2-5=3x+4$

$4x^2 - 3x - 5 - 4 = 0$

$4x^2 - 3x -9 = 0$

$x= \dfrac{3 \pm \sqrt{3^2 - 4(4)(-9)}}{2(4)}$

$x = \frac 1 8 (3 \pm \sqrt{9(1 + 16)})$

$x = \frac 1 8 (3 \pm 3\sqrt{17})$
