True

Technically, since the larger triangle is given first, you compare it first to the smaller.

16 x 1/4 = 4

1/4 is the ratio.

hope this helps

MARKING BRAINLIEST IF U HELP 19 - s = 13; s = -6 yes no question

avanturin [10]

Answer:

Step-by-step explanation:

We have the equation 19 - s = 13, and are asked to determine whether s = -6 fits in.

To solve, we need to isolate "s", do as followed and subtract 19 from both sides :

s = -6

Since this is equal to what the question is asking, yes s = -6 is correct.

Write the first five terms of the sequence defined by the recursive formula

stepan [7]

<u>Answer:</u>

The correct answer option is: $S_9=\frac{9}{2} (2+26)$

<u>Step-by-step explanation:</u>

We know that,

the sum of the first $n$ terms of an Arithmetic Sequence is given by:

$S_9=\frac{n(a_1+a_n)}{2}$

where $n$ is the number of terms,

$a_1$ is the first term of the sequence; and

$a_n$ is the first term of the sequence.

So for $a_n=3n-1$ ,

$a_1=3(1)-1=2$

and

$a_9=3(9)-1=26$

Putting these values in the formula to get:

$S_9=\frac{9(a_1+a_9)}{2}$

$S_9=\frac{9(2+26)}{2} \\\\S_9=\frac{9}{2} (2+26)$

<u>First five terms:</u>

$a_1=3(1)-1=2$

$S_1=\frac{1(2+2)}{2}$ =2

$a_2=3(2)-1=5$

$S_2=\frac{2(2+5)}{2}$ =7

$a_3=3(3)-1=8$

$S_2=\frac{3(2+8)}{2}$ =15

$a_4=3(4)-1=11$

$S_4=\frac{4(2+11)}{2}$ =26

$a_5=3(5)-1=14$

$S_5=\frac{5(2+14)}{2}$ =40
