What is the value of the 30th term in the following arithmetic sequence? 12, 6, 0, -6, ... HELP!!!!

30 times by 6 because it goes down by 6 which is 180 and take awat from 12 which is -168
And don't forget that it is a negative. so leave a minus before the number.

The value of the 30th term is <em>-168</em><em />

According to our sequence, we are subtracting 6 every time. If we look at our number line though, we notice that we start 2 terms before we get to zero, so we an multiply our -6 by 28 because when we multiply we start from zero and the term we are wanting, our 30th term, is actually 28 terms away from zero. So:

-6 * 28 = -168

And this is our answer of the 30th term in the arithmetic sequence.

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if you have nay further questions! :D

Write a real-life word problem that corresponds to the equation below.

ella [17]

The real life problem that corresponds to the equation will be "The area of a farmer's square garden is 144 square feet. What is the length of the garden?"

<h3>How to solve the equation</h3>

A real-life word problem that corresponds to the equation x² = 144 will be that the area of a farmer's square garden is 144 square feet. What is the length of the garden?

In this case, the length of the garden will be the square root of 144. This will be calculated thus:

x² = 144

x = ✓144

x = 12

Therefore, the length of the garden is 12 feet.

5 less than the square of a number

yanalaym [24]

x^2 - 5 this will be the equation formed.

<h3>What is exponents?</h3>

An exponent is the number of times a number is multiplied by itself. For example, 2 to the third (written as 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of one is itself.

<h3>Calculation </h3>

let the number be x

x^2 - 5 this will be the equation formed

Given f of x equals 5 times x minus 6 for x less than 3, equals x squared for x between 3 and 5 inclusive, and equals 2 times x

konstantin123 [22]

Answer:

<em>D. 5 for x less than or equal to 4, equals 2x for x between 4 and 6 including 6, and equals 4 for x greater than 6 Domain: All real number</em>s.

Step-by-step explanation:

Find the complete diagram attached

First we need to get the derivative of the functions

For the function f(x) = 5x - 6

Using the formula

If f(x) = axⁿ

f'(x) = naxⁿ⁻¹

For the function f(x) = 5x - 6

f'(x) = 1(5)x¹⁻¹

f'(x) = 5x⁰

f'(x) = 5

For the function f(x) =x²-2

f'(x) = 2x²⁻¹

f'(x) = 2x

For the function f(x) = 4x+10

f'(x) = 1(4)x¹⁻¹

f'(x) = 4x⁰

f'(x) = 4

Get the domain

The domain is the value of the input variable x for which the functions exists. For the functions given, the domain will be on all real numbers i.e the functions will exists for any value of x on the number line.

Hence Option D is correct

An arrangement of flowers originally priced at $48.00 is marked down to $39.00. What is the percent of decrease, rounded to the

Mashcka [7]

The answer is C

So how?

I multiplied 48*.19= 9.12 then subtracted that from 48 and got 38.88 which rounds to 39

C is the answer

I hope this helps! :D
