Plz helpppp fast plzzzzz Write the sum using summation notation, assuming the suggested pattern continues. -3 + 6 + 15 + 24 + ..

Olin [163]

Answer:

It is the first choice.

Step-by-step explanation:

This is a sequence where

the next term is obtained by adding 6.

first term = -9 + 6(0) = -9

second term = -9 + 6(1) = -3

third term = -9 + 6(2) = 3

4th term = -9 + 6(3) = 9

and 81 = -9 + (6*15).

So the answer is Sigma (-9 + 6n) from n= 0 to n = 15.

Part 2 - Find the error(s) and solve the problem correctly.

JulijaS [17]

The problem solved correctly as a single logarithm is $log_{a} 2x^{3}/y^{2}$

<h3>Simplifying Logarithm</h3>

From the question, we are to simplify the given logarithm

The given logarithm is

$log_{a} 2x \ + \ 2(log_{a} x -log_{a} y)$

From the subtraction law of logarithm, we have that

$log_{c} a -log_{c} b = log_{c} (a/b)$

Thus,

The error in the solution was instead of multiplying, a was supposed to be divided by b

The correct solution is

$log_{a} 2x \ + \ 2(log_{a} x -log_{a} y)$

$log_{a} 2x \ + \ 2(log_{a} (x/y) )$

$log_{a} 2x \ + \ log_{a} (x/y)^{2}$

$log_{a} 2x \ + \ log_{a} (x^{2}/y^{2})$

Simplifying further

$log_{a} 2x \times (x^{2}/y^{2})$

$log_{a} 2x \times x^{2}/y^{2}$

$log_{a} 2x^{3}/y^{2}$

Hence, the problem solved correctly as a single logarithm is $log_{a} 2x^{3}/y^{2}$

D divided by 4 plus 12 = 20<br> show steps<br> what is d

tester [92]

Answer:

d=32!!!

Step-by-step explanation:

So first rewrite it as an equation: d/4+12=20

d/4+12=20 then subtract 12 from both sides to balance the equation

d/4=8 so multply both sides by 4 to isolate the variable, 4(d/4)=d =d and 8x4=32, so d=32
