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

Sum of first 20 terms

<h3>Solution</h3>

First, let's get the value of the first term:

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

Next, let's find the sum of the first 20 terms

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

Answer is 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.

Evaluate and match each expression on the left to its value on the right, when x=8 and y=3.

Crank

Answer:

12-y------------> 9

3x-y------------>21

4y-10----------->2

1/4 xy-----------> 6

Solution,

Given,

X=8

y=3

Now,

$1. \: \: 12 - y \\ \: \: \: = 12 - 3 \\ \: \: = 9 \\ 2. \: \: 3x - y \\ \: \: = 3 \times 8 - 3 \\ \: \: = 21 \\ 3. \: \: 4y - 10 \\ \: \: = 4 \times 3 - 10 \\ \: = 12 - 10 \\ \: \: = 2 \\ 4. \: \: \frac{1}{4} xy \\ \: \: = \frac{1}{4} \times 8 \times 3 \\ = 6$

hope this helps...

Good luck on your assignment...
