Step-by-step explanation:

The calculation of size for a new television is shown below:-

With the help of Pythagoras theorem

[tex]h^2 = b^2 + p^2[/tex]

where

h indicates hypotenuse which is the diagonal length

b indicates the base which is the length of the horizontal side

p indicates perpendicular which is the TV length of the vertical side.

[tex]h^2 = \sqrt{b^2 + p^2}[/tex]

now, we will put the values into the above formula

[tex]= \sqrt{32^2 + 18^2} \\\\ = \sqrt{1024 + 324} \\\\ = \sqrt{1348}[/tex]

Which gives result

= 36.7

or

= 37

Answer: x=6 y=3 z=2

Step-by-step explanation: The question is very vast so im guessing that its just finding 3 whole numbers that can equal the same ammount being multipied by 2 and 3. I chose 6. But theres many others. The answer should be correct because if we replace the letters with the numbers i put in the answer it should look like this: 6=2•3=3•2

When we do simplify this we should get 6=6=6 which is true.

Again you can use different numbers for example 12 as X. Then you need to divide 12 by whats behind the Y. So 12÷2 is 6. So Y is equal to 6. To find Z all you need to do is follow the same steps as Y. Find the number behind Z (3) and divide that into 12. So it would be 12÷3. And if you do the math right it should look like this: X=12, Y=6, Z= 4. And when you imput the numbers to thier corresponding letter it should look like this 12=2(6)=3(4) which simplified looks like 12=12=12 which is true.

Answer:

- 1/2

Step-by-step explanation:

(-4/5) × (- 5/8)

- 4/5 × - 5/8

First we mulitply across

The top and the bottom.

- 20 / 40

because -4 × -5 = +20

and -5 × -8 = +40

Now we simplify the fraction

- 20 / 40

= - 2 /4

= - 1/2

Because we have to simplify it and so I divided it by 10 first.

-20 ÷ 10 = -2 and -40 ÷ 10 = -4

Then I simplified it again by dividing it by 2.

-2 ÷ 2 = -1 and -4 ÷ 2 = -2

So finally we have:

-1/2

And we cannot simplify that anymore so that is the answer.

Hope that helped!

as we know, the integral of [tex]x^{n}[/tex] is [tex]\frac{x^{n+1} }{n+1}[/tex]

so, the integral of x.[tex]2^{x}[/tex] will be found as follows:

∫uv dx = u∫v dx - ∫[(du/dx)* ∫v dx] dx

∫x.[tex]2^{x}[/tex] dx = x∫[tex]2^{x}[/tex] - ∫[(dx/dx) * ∫[tex]2^{x}[/tex] dx ] dx

∫x.[tex]2^{x}[/tex] dx = x*[tex]\frac{2^{x+ 1}}{x+ 1}[/tex] - 1 * [tex]\frac{2^{x + 1} }{x + 1}[/tex]

Ordered pair (0, 0) & (0.5, 2.5)  will fall on the line of graph

Step-by-step explanation:

Megan expects to save an average of 5 dollars per week from her babysitting earnings.

=> Saving Per  week  = 5 $

Saving in 0.5 Week = 0.5 * 5 = 2.5 $

hence ordered pair (0.5, 2.5)  will fall on the line of graph

Saving in 3 Week = 3 * 5 = 15 $

Hence (3, 18) will not fall on  line

Saving in 0 Week = 0.5 * 0 = 0 $

hence ordered pair (0, 0)  will fall on the line of graph

Saving in 4.5 Week = 4.5 * 5 = 22.5 $

Hence (4.5, 30) will not fall on  line

Ordered pair (0, 0) & (0.5, 2.5)  will fall on the line of graph

In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.

here, we have,

Megan expects to save an average of 5 dollars per week from her babysitting earnings.

=> Saving Per  week  = 5 $

Saving in 0.5 Week = 0.5 * 5 = 2.5 $

hence ordered pair (0.5, 2.5)  will fall on the line of graph

Saving in 3 Week = 3 * 5 = 15 $

Hence (3, 18) will not fall on  line

Saving in 0 Week = 0.5 * 0 = 0 $

hence ordered pair (0, 0)  will fall on the line of graph

Saving in 4.5 Week = 4.5 * 5 = 22.5 $

Hence (4.5, 30) will not fall on line

Hence, Ordered pair (0, 0) & (0.5, 2.5)  will fall on the line of graph.

Answer:327412000

Step-by-step explanation:

Answer:

406.4

Step-by-step explanation:

When rounding you only look at the number you're rounding and the one before it. In this case it would be the 4 and 3 after the decimal since we're rounding to the nearest cent. If the numbers before the one you're rounding are 0-4 then you leave the number the same. If the numbers are between 5-9 then you add one to the number. Since the number before 4 is between 0-4 you leave it as 4. But if it was between 5-9 then you'd change the 4 to 5.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{e = - 4}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{6(3 - e) = 42}[/tex]

Distribute 6 through the parentheses

⇒[tex] \sf{18 - 6e = 42}[/tex]

Move 18 to right hand side and change it's sign

⇒[tex] \sf{ - 6e = 42 - 18}[/tex]

Subtract 18 from 42

⇒[tex] \sf{ - 6e = 24}[/tex]

Divide both sides of the equation by -6

Calculate

Answer:

a. True

Step-by-step explanation:

This is because, since the sample mean equals the population means, the distribution of the sample means about the sample size would also be the distribution of the sample size distributed about the population mean.

This usually results in a normally distributed population for a sample size greater than 30.

So, if the sample size is greater than 30, the population mean and sample mean would have the same value and distribution.

x=0

Step-by-step explanation:

First, we distribute on both sides

6x+6-5x=8+2x-2

x+6=2x+6

subtract x from both sides

6=x+6

subtract 6 from both sides

x=0

6x + 6 - 5x = 8 + 2x - 2 (Rearrange expression)

6x - 2x - 5x = 8 - 6 - 2 (Combine like terms)

The perimeter is the distance around a shape. Let's add up the lengths of our sides to ind it.

x+5x-2+7x-3

We combine all of the x values.

x+5x+7x=13x

And all of the constants.

Answer:

The correct answer would be 200, but in your case 166 is the closest

Step-by-step explanation:

divide 1000 by 5

The total number of bags needed are 200 bags.

We have Cole who has purchased 1,000 pounds of jellybeans. Each bag contains 5 pounds of jellybeans.

We have to determine how many party bags can make 1,000 pounds of jellybeans.

The total number of packets(n) required will be -

[tex]$n=\frac{x}{y}[/tex]

According to the question, we have -

Amount of jelly beans in a bag - 5 pounds.

Amount of jelly beans needed - 1000 pounds.

Assume that the number of bags needed are n. Then -

n = [tex]\frac{1000}{5}[/tex] = 200 Bags.

Hence, The total number of bags needed are 200 bags.

Answer:

is it acceleration or velocity?

Step-by-step explanation:

Answer:

Length is 28. Width is 8.

Step-by-step explanation:

The perimeter of a rectangle is given by the following formula:

[tex]P=2l+2w[/tex]

We know that the length is 4 inches less than 4 times the width. Therefore:

[tex]l=4w-4[/tex]

Substitute this for l. Let's also substitute 72 for P. Therefore:

[tex]72=2(4w-4)+2w[/tex]

Distribute:

[tex]72=8w-8+2w[/tex]

Combine like terms:

[tex]72=10w-8[/tex]

Add 8 to both sides:

[tex]80=10w[/tex]

Divide both sides by 10:

[tex]w=8[/tex]

Therefore, the width is 8.

The length is 4 less than 4 times the width. Thus: "

[tex]l=4(8)-4[/tex]

Multiply:

[tex]l=32-4[/tex]

Subtract:

[tex]l=28[/tex]

Therefore, the length is 28 and the width is 8.

Answer:

A. 44.82%

B.

Option b. Return On Equity usually increases since the repurchase of shares reduces the denominator (avg. stockholders' equity)

C.

Option b. The Companies would tend to repurchase their own stock if they feel the stock is been undervalued by the market

Step-by-step explanation:

a. Computation for return on equity for 2015

Using this formula

Return on equity = The Net income amount /The Average stockholders' equity amount

Let plug in the formula

Return on equity=2,634.4/[(5,605+6,151)/2]

Return on equity=2,634.4/(11,756/2)

Return on equity=2,634.4/5,878

Return on equity=0.4482×100

Return on equity= 44.82%

b. In a situation where they repurchased over $1.4 billion of its common stock in the year 2015 this means that the RETURN ON EQUITY will usually tend to increases reason been that the repurchase of shares will often reduces the denominator (average stockholders' equity)

Therefore the repurchase increase Starbucks’ Return On Equity.

c. In a situation where Starbucks had not repurchased common stock in the year 2015, what their Return On Equity would have been is that they will repurchase their own stock if they feel the stock is been undervalued by the market

Answer:

  all real numbers except x=2

Step-by-step explanation:

We assume you intend c(x) = 5/(x-2), rather than c(x) = (5/x) -2 as written.

__

The domain of c(x) is real numbers, excluding 2. Multiplying c(x) by d(x) doesn't change that.

The domain of (cd)(x) = c(x)×d(x) = 5(x+3)/(x-2) is "all real numbers except 2".

2 is excluded because c(x) is undefined for that value.

Where n = 52 and r = 5

[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex] becomes
