Answer:

There are plenty of unique ways to wrap presents beautifully. The quickest way that doesn't even require a box: Create a gift bag out of another ..

Step-by-step explanation:

There's something about a pile of presents under the tree that catches the eye—no matter how they're wrapped. But when your gifts look like something straight out of a storybook, it instantly adds to the Christmas magic.

We know what you're thinking, though: Who has time for that between decorating the house, shopping for your loved ones, prepping for the Christmas party, and planning your holiday meal? What if we told you that creating presents that look professionally wrapped is actually fairly simple?

There are plenty of unique ways to wrap presents beautifully. The quickest way that doesn't even require a box: Create a gift bag out of another household staple, like an old (but clean) pillowcase or a brown paper bag. You'd be surprised what a simple stamp, paint pen, or stylish ribbon can do to breathe new life into these objects. But if you have a little more time to get creative, why not raid your craft closet and make something truly special and Pinterest-worthy, like lace-covered packages or custom paper created by your kids?

No matter which direction you go and no matter what holiday you're celebrating—Christmas, a kids' birthday, or a life event like a wedding or a baby shower—you'll find plenty of inspiration, plus step-by-step gift wrapping instructions, here. When you're done, we're certain that present is going to be so pretty, it'll almost be too hard to open

Chen completed the division problem below.
Lelechka [254]

Answer:

The error is:

He multiplied the dividend by 100 instead of 10

Step-by-step explanation:

∵ 1.926 ÷ 0.9 ⇒ means

  1.926 = 1926/1000 ⇒ dividend

  0.9 = 9/10 ⇒ divisor

* \frac{1926}{1000} ÷ \frac{9}{10}

 \frac{1926}{1000} × \frac{10}{9}

 \frac{1926}{100} × \frac{1}{9}

∵ 1926/100 = 19.26 ⇒ dividend

∴ 19.26 ÷ 9 = 1926/100 ÷ 9

  19 ÷ 9 = 2 with remainder 1/9

  12 ÷ 9 = 1 with remainder 3/9

  36 ÷ 9 = 4 no remainder

∴ The quotient is 214/100 = 2.14

Find all values of c in the open interval (a, b) such that f'(c)=(f(b)-f(a))/(b-a)
timama [110]
<h3>Answer:   c = 7/4</h3>

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

Work Shown:

Compute the function value at the endpoints

f(x) = \sqrt{4-x}\\\\f(-5) = \sqrt{4-(-5)} = 3\\\\f(4) = \sqrt{4-4} = 0\\\\

With a = -5 and b = 4, we have

f'(c) = \frac{f(b)-f(a)}{b-a}\\\\f'(c) = \frac{f(4)-f(-5)}{4-(-5)}\\\\f'(c) = \frac{0-3}{9}\\\\f'(c) = -\frac{1}{3}\\\\

So,

f(x) = \sqrt{4-x}\\\\f'(x) = -\frac{1}{2\sqrt{4-x}}\\\\f'(c) = -\frac{1}{3}\\\\-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\

Use algebra to solve for c

-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\\frac{1}{2\sqrt{4-c}} = \frac{1}{3}\\\\3 = 2\sqrt{4-c}\\\\2\sqrt{4-c} = 3\\\\\sqrt{4-c} = \frac{3}{2}\\\\4-c = \frac{9}{4}\\\\c = 4-\frac{9}{4}\\\\c = \frac{16-9}{4}\\\\c = \frac{7}{4}\\\\

What is the slope of the line that is parallel to y=−5x+7?
zheka24 [161]

Answer:

-5

Step-by-step explanation:

<u>Slope- intercept form:</u>

y= mx +c, where m is the slope and c is the y-intercept

Since the given equation is already in the slope-intercept form, we can identify its slope by looking at the coefficient of the x term. Here the coefficient is -5, thus the slope of the given line is also -5.

Parallel lines have the same slope. Thus, the slope of the line that is parallel to y= -5x +7 will have a slope of -5.
