Well you have to first find the constant of Brand X which would be 2.70/10 = .27. Brand Y is .4 more so that would be .31 per ounce. So then .31 x 11 = 3.41. The cost of 11 ounces of brand Y is $3.41.

a glacier receded 4 feet a day for a period of 25 days. how much shorter was the glacier at the end of the period.
dangina [55]

Alright, lets get started.

In the question given that glacier receded 4 feet a day for a period of 25 days.

Which shows in 1 day, it recedes = 4 feet

means in 1 day, the height of the glacier gets shorter = 4 feet

So, in 25 days, the height of the glacier gets shorter = 4 * 25

So, in 25 days, the height of the glacier gets shorter = 100 feet

It means the glacier will get 100 feet shorter at the end of the period of 25 days. : Answer

Hope it will help :)

I’m Really lost if I could get a answer it would be greatly appreciated

<h3>Answers:</h3>

f(g(x)) = \sqrt{x^2+5}+5\\\\g(f(x)) = x+30+10\sqrt{x-1}

================================================

Work Shown:

Part 1

f(x) = \sqrt{x-1}+5\\\\f(g(x)) = \sqrt{g(x)-1}+5\\\\f(g(x)) = \sqrt{x^2+6-1}+5\\\\f(g(x)) = \sqrt{x^2+5}+5\\\\

Notice how I replaced every x with g(x) in step 2. Then I plugged in g(x) = x^2+6 and simplified.

------------------

Part 2

g(x) = x^2+6\\\\g(f(x)) = \left(f(x)\right)^2+6\\\\g(f(x)) = \left(\sqrt{x-1}+5\right)^2+6\\\\g(f(x)) = \left(\sqrt{x-1}\right)^2+2*5*\sqrt{x-1}+\left(5\right)^2+6\\\\g(f(x)) = x-1+10\sqrt{x-1}+25+6\\\\g(f(x)) = x+30+10\sqrt{x-1}\\\\

In step 4, I used the rule (a+b)^2 = a^2+2ab+b^2

In this case, a = sqrt(x-1) and b = 5.

You could also use the box method as a visual way to expand out \left(\sqrt{x-1}+5\right)^2

Step by step directions Square root for 480

<span>  <span>first off your answer is 21.90 and the step by step i  wrote it for you:) Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. </span> The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.   </span>                                                                                                                                                                          <span>Many mathematical operations have an inverse, or opposite, operation. Subtraction is the opposite of addition, division is the inverse of multiplication, and so on. Squaring, which we learned about in a previous lesson (exponents), has an inverse too, called "finding the square root." Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 … </span> The square root of a number, n, written <span> is the number that gives n when multiplied by itself. For example,</span> <span>because 10 x 10 = 100</span> Examples Here are the square roots of all the perfect squares from 1 to 100. Finding square roots of of numbers that aren't perfect squares without a calculator 1. Estimate - first, get as close as you can by finding two perfect square roots your number is between. 2. Divide - divide your number by one of those square roots.
3. Average - take the average of the result of step 2 and the root. <span>4. Use the result of step 3 to repeat steps 2 and 3 until you have a number that is accurate enough for you.
</span> Example: Calculate the square root of 10 () to 2 decimal places. <span>1. Find the two perfect square numbers it lies between.
</span> <span><span>Solution:
</span><span>32 = 9 and 42 = 16, so lies between 3 and 4.</span></span> <span>2. Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)</span> <span>3. Average 3.33 and 3. (3.33 + 3)/2 = 3.1667</span> <span>Repeat step 2: 10/3.1667 = 3.1579</span><span>Repeat step 3: Average 3.1579 and 3.1667. (3.1579 + 3.1667)/2 = 3.1623</span> Try the answer --> Is 3.1623 squared equal to 10? 3.1623 x 3.1623 = 10.0001 If this is accurate enough for you, you can stop! Otherwise, you can repeat steps 2 and 3. <span>Note: There are a number of ways to calculate square roots without a calculator. This is only one of them.</span>         <span><span>
