Find the sum of first 20 to terms of an ap in which d is equal to 7 and 20 second term is 149​
GuDViN [60]

Answer:

1370

Step-by-step explanation:

<h3>Given</h3>
  • AP with d= 7 and a₂₂ = 149
<h3>To find</h3>
  • Sum of first 20 terms
<h3>Solution</h3>

<u>First, let's get the value of the first term:</u>

  • aₙ = a + (n-1)d
  • a₂₂ = a + 21d
  • 149 = a + 21*7
  • a = 149 - 147
  • a= 2

<u>Next, let's find the sum of the first 20 terms</u>

  • Sₙ = 1/2n(2a+ (n-1)d)
  • S₂₀ = 1/2*20(2*2 + 19*7) = 10(4 + 133) = 10*137 = 1370

<u>Answer is</u> 1370

The black graph is the graph of
posledela

Option-B is correct that is y=f(x/-1) determines the reflection of the graph y=f(x) across the y-axis.

Given that,

The graph in black represents the y = f(x).

We have to pick the equation for the graph in red graph.

We know that,

The black graph is the graph of y=f(x).

The black graph is reflected across the y-axis in the red graph.

A. y=(x-1) determines the translation of the graph y=f(x) one unit to the right.

B. y=f(x/-1) determines the reflection of the graph y=f(x) across the y-axis.

C. y-1=f(x) determines the translation of the graph y=f(x) one unit up.

D. y/-1=f(x) determines the reflection of the graph y=f(x) across the y-axis.

Therefore, Option-B is correct that is y=f(x/-1) determines the reflection of the graph y=f(x) across the y-axis.
