Step-by-step explanation: I have attached the equation in the image provided.

Don't be intimidated by the fraction that appears on the left side of this equation. We start this problem by distributing or multiplying through the parentheses on both sides.

So as we distribute the 1/5 through the parentheses on the left side of the equation, we get 1/5 × y which is y/5 and 1/5 × -1 which is -1/5. On the right, let's change the -2 to + and negative 2 so we know that we're distributing a -2 through the parentheses. When we do that, the right side of the equation simplifies to 6 - 8 + 2y.

Now we have y/5 - 1/5 = 6 - 8 + 2y. Notice that we can go one step further with the right side of the equation as it simplifies to -2 + 2y.

Now we have y/5 - 1/5 = -2 + 2y.

Now we are ready to get rid of the fractions.

Since both fractions have a denominator of 5, we can get rid of the fractions by multiplying both sides of the equation by 5. Make sure you distribute the 5 through both terms on both sides of the equation.

On the left our 5's cancel and we're left with y - 1. On the right, 5 × -2 is -10 and 5 × 2y is 10y.

Now we have y - 1 = -10 + 10y.

From here, we add 1 to both sides of the equation and then we get the following equation. y = -9 + 10y

Now we subtract 10y from both sides of the equation and we get -9y = -9. From here, we divide both sides of the equation by -9 and we get y = 1.

In the image provided, I have only attached steps up to y - 1 = -10 + 10y but the rest of the work is explained above.

Answer:  \bold{a)\quad 51, 54, 57\qquad a_n=a_{n-1}+3}

               \bold{b)\quad 250, 625, 1562.5\qquad a_n=(2.5)a_{n-1}}

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

a) This is an arithmetic sequence where 3 is added to the previous term.

48 + 3 = 51

              51 + 3 = 54

                            54 + 3 = 57

The recursive formula for this sequence is:  a_n = a_{n-1}+3

*****************************************************************************************

b) This is a geometric sequence where 2.5 is multiplied to the previous term.

100(2.5) = 250

                250 (2.5) = 625

                                    625(2.5) = 1562.5

The recursive formula for this sequence is: a_n=(2.5)a_{n-1}

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Viktor [21]

Answer:

Step-by-step explanation:

Triangle IJK is a right angle triangle.

From the given right angle triangle

JK represents the hypotenuse of the right angle triangle.

With ∠K as the reference angle,

IK represents the adjacent side of the right angle triangle.

IJ represents the opposite side of the right angle triangle.

To determine Cos K, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse. Therefore,

Cos K = 36/85

Cos K = 0.4235

Rounding up to the nearest hundredth,

Cos K = 0.42

How do you find the square root of 2809
Hunter-Best [27]
If this is greater than the first part of the number called by the spectator (i.e., ignoring the last two digits), then the last digit of your answer is the lower of the two possible values. Otherwise the last digit is the higher value. For example if the number called is 2809, the square root could be either 53 or 57.
