Answer:

[tex]x=23/\sqrt{6}[/tex],

[tex]y= \frac{23}{6\sqrt{6}}[/tex]

Step-by-step explanation:

From the question we are told that

Surface area is 529 square meters

Generally the dimensions of the cuboid

[tex]v=x^y[/tex]

[tex]D=4xy+2x^2 =529[/tex]

[tex]V=x^29(\frac{529-6x^2}{4x})[/tex]

[tex]V' =529-6x^2/4[/tex]

[tex]v'=0[/tex]

Therefore

[tex]529=6x^2[/tex]

[tex]x=\sqrt{\frac{529}{6} }[/tex]

[tex]x=23/\sqrt{6}[/tex]

Mathematically

[tex]v''=\frac{12x}{4}[/tex]

[tex]v''=-3\frac{23}{\sqrt{6} }<0[/tex]

[tex]y= \frac{529-2*(\frac{529}{6} }{4*\frac{23}{\sqrt{6} } }[/tex]

[tex]y= \frac{23}{6\sqrt{6}}[/tex]

Therefore

[tex]x=23/\sqrt{6}[/tex]

and

[tex]y= \frac{23}{6\sqrt{6}}[/tex]

Step-by-step explanation:

1. if to calculate the length of AB; AC and BC, then:

[tex]|AB|=\sqrt{(2-0)^2+(3-0)^2} =\sqrt{13}.[/tex]

[tex]|AC|=\sqrt{(4-0)^2+(0-0)^2} =4.[/tex]

[tex]|BC|=\sqrt{(2-4)^2+(0-3)^2}= \sqrt{13}.[/tex]

2. if to compare the calculated lengths, then:

AB=BC. It means the given triangle is isosceles.

Answer:

46 units.

Step-by-step explanation:

To find the perimeter, you need to add up all the sides. Knowing this, we can set up an equation to solve for y.

2(5y + 1) + 2(4y + 3) = 170

10y + 2 + 8y + 6 = 170

18y + 8 = 170

18y = 162

y = 9

Now that we know y = 9, we can solve for vw.

vw = 5(9) + 1

vw = 45 + 1

vw = 46

Therefore, line vw is 46 units.

Answer: VW=11

4y+3=5y+1

2=y

Answer: its 60.......

Answer:

17.44 ft.

Step-by-step explanation:

Given,

The Distance of the hot air balloon: 110 ft

Change in elevation, [tex]\theta_1 = 25^0, \theta_2 = 32[/tex]

We know that,

[tex]\tan \theta = \dfrac{Perpendicular}{base}[/tex]

Now,

[tex]\tan \theta_1 = \dfrac{h_1}{110}[/tex]

[tex]\tan 25^0= \dfrac{h_1}{110}[/tex]

[tex]h_1 = 51.294\ ft[/tex]

[tex]\tan \theta_2= \dfrac{h_2}{110}[/tex]

[tex]\tan 32^0= \dfrac{h_2}{110}[/tex]

[tex]h_2 = 68.736\ ft[/tex]

Rise of balloon = 68.736 - 51.294

                         = 17.442 ft

                         = 17.44 ft

Hence, the rise of the balloon rise is 17.44 ft.

Step-by-step explanation:

From the answer choices available the answer that is correct is that for day-to-day business data analysis, most firms rely on a large staff of expert statisticians. This is because on a daily basis firms receive large sets of data from all of their business movements, therefore a large staff of highly experienced individuals is needed in order to handle and document all of these numbers carefully so that no mistakes are made. The smallest mistake in the firm's financial accounts can lead to a very costly loss for the company.

Answer:

The percentage increase would be 20%

Step-by-step explanation:

worked it out

The percent increase from 15 to 18 is 20%.

To find the percent increase from 15 to 18, we can use the following formula Subtract the initial value from the final value, then divide the result by the absolute value of the initial value.

Percent Increase = (New Value - Old Value) / Old Value * 100

Using this formula, let's calculate the percent increase:

Percent Increase = (18 - 15) / 15 * 100

Percent Increase = 3 / 15 * 100

Percent Increase = 0.2 * 100

Percent Increase = 20

Therefore, the percent increase from 15 to 18 is 20%.

Answer:

I agree with Mo.

Step-by-step explanation:

Considering Mo's chart;

0        Tth       Hth      Thth

           1            2          1           = 0.121

Considering Annie's chart;

0        Tth       Hth      Thth

           0         12          1           = 0.0121

From the results obtained from Mo and Annie's chart, only Mo's chart show a grid of of 0.121.

Thus, I agree with Mo.

End behavior means what are the y-values doing as the x-values both increase and decrease without bound.

This is a parabola (degree 2) with a negative leading coefficient (−0.25). Therefore both ends of the graph will be going towards negative infinity.

As x increases, f(x) decreases.

As x decreases, f(x) decreases.

Since the highest degree of the given function, f(x) = -0.25x² – 2x + 1 the end behavior of the graph will be down.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that,

f(x) = -0.25x² – 2x + 1

A polynomial function's end behavior defines how the graph acts as x gets closer. The leading term of the function—that is, the term with the highest n-value for a  × n, where n is a positive integer and an is any nonzero number—allows us to infer the function's final behavior.

The highest degree of the given function is 2. When the function is plotted on the graph we get the graph shows downward behavior when x gets closer.

Thus, since the highest degree of the given function, f(x) = -0.25x² – 2x + 1 the end behavior of the graph will be down.

Answer:

x = 5

Step-by-step explanation:

In this question, you would solve for x.

Solve:

2(x + 3) = 4(x - 1)

Use the distributive property.

2x + 6 = 4x - 4

Subtract 4x from both sides.

-2x + 6 = -4

Subtract 6 from both sides.

-2x = -10

Divide both sides by -2

x = 5

The value of x is 5.

Answer:

18

Step-by-step explanation:

15 + 20% = 18

If Hailey increased her points by 20%, she would score 18 points this week. Therefore, what we need to do is to multiply 15 by 0.20. How did we get 0.20? Well, we divided 20 by 100 to get 0.20. Anyway, once we have multiplied 15 by 0.20, we get 3. However, this answer would not be logical because she increased her points by 20% - we are going up and not down. So, we add 15 and 3 together to get a total of 18 points scored.
