Answer:

Ok so what you have to do to is basically apply Pythagoras Theorem

Step-by-step explanation:

The hypotenuse squared is equal to the sum of the squares of the legs of a right-angle triangle.

[tex]c^2 = a^2 + b ^2[/tex]

Assuming:

c = 10 [tex]\rightarrow[/tex] hypotenuse

a = 6.84 [tex]\rightarrow[/tex] adjacent leg (base of the triangle)

b = ? [tex]\rightarrow[/tex] opposite leg (height of triangle)

[tex]10^2 = 6.84^2 + b^2[/tex]

[tex]b^2 = 10^2 - 6.84^2[/tex]

[tex]b = \sqrt{(10)^2-(6.84)^2}[/tex]

[tex]b = 7.295[/tex]

With that, you can calculate the area of the triangle:

[tex]A_{triangle} = \frac{a*b}{2}[/tex]

[tex]A_{triangle} = \frac{6.84*7.295}{2}[/tex]

[tex]A_{triangle} = 24.95[/tex]

And as your polygon has 9 sides, you can assume that you have 9 of this triangles, so the total area would be:

[tex]A = 9*24.95[/tex]

[tex]A = 224.55[/tex]

And rounding this result to the nearest hundreth:

[tex]A = 220[/tex]

Answer:

Where's the image?

cause i can't solve the question without the image

Step-by-step explanation:

If two objects vary directly, we just divide those two objects.

If two objects vary indirectly, we multiply them.

So here we have

[tex] \frac{v}{ {x}^{2} } {y}^{3} = k[/tex]

where k is a constant.

So let analyze when all variables Except k is given.

[tex] \frac{2}{16} (27) = 3.375[/tex]

So k=3.375

[tex] \frac{v}{ {3}^{2} } (2 {}^{3} ) = 3.375[/tex]

[tex] \frac{v}{9} (8) = 3.375[/tex]

[tex] \frac{v}{9} (8) = \frac{27}{8} [/tex]

[tex]v8 = \frac{243}{8} [/tex]

[tex]v = \frac{243}{64} [/tex]

[tex]3.796875[/tex]

Answer:

15: 10.99

2(3.14)r

3.5/2 = 1.75

2(3.14)1.75

10.99

16: 50.24

2(3.14)8

50.24

17: 260%

2 = 200%

3/5 = 60%

200 + 60 = 260%

Answer:

-5 and -5.

Step-by-step explanation:

Two negative numbers multiply to make a positive and add to make a negative.

Answer:I think it’s 7...

Step-by-step explanation:

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

[tex]y=\stackrel{\stackrel{m}{\downarrow }}{5}x+3\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

that means that the slope of line L is also 5, or 5/1 or   [tex]slope=\cfrac{\stackrel{rise}{5}}{\underset{run}{1}}[/tex]

Check the picture below.

Answer:

$120

Step-by-step explanation:

10% = 1/10

If Jay has only saved 1/10 of his goal, then to find how much the goal is we multiply how much he has by 10. This will convert 1/10 to 1.

12 x 10 = 120

Jay's goal is $120

Answer:

$120

284.58-17.95=266.63

266.63/0.91=293

293 miles

Answer:

4.5 miles

Step-by-step explanation:

Since she walked at a rate of 3 miles for 1.5 hours, you have to multiply both together (1.5 x 3) and you get 4.5 miles

Step-by-step explanation:

See attached image for the answer

-4(y + 6) + 5y

= -4y - 24 + 5y

Answer:

Step-by-step explanation:

I am assuming that i = √(-1)

3i*2i*(m + i)

= 6i^2(m + i)

= -6(m+ i)

= -6m - 6i.

Answer:

106.25 mph

Step-by-step explanation:

since the car travels at 85 miles per hour we divide it by 60 seconds in order to find how many miles is it to get in a minute

=> 85mph ÷ 60

divide 85 by 60

=> 1.416

multiply 1.416 by 15 to get how many miles it to go in 15 minutes

=> 21.25

then add it to 85

=> 106.25

Answer:

4.5

Step-by-step explanation:

the square root of 20 is closer to 4.5 than it is to 4.4

Step-by-step explanation:

The key word "per" hints at a ratio

A ratio is represented by ?:?, ?/?, etc

So, we can divide the two

Answer:

The range consisting of the p-value is, 0.000001 < p-value < 0.00001.

Step-by-step explanation:

The dependent t-test (also known as the paired t-test or paired samples t-test) compares the two means associated groups to conclude if there is a statistically significant difference amid these two means.

In this case a paired t-test is used to determine whether the percent population growth rate of major cities has decreased compared to the last decade.

The alternative hypothesis is Hₐ: [tex]\mu_{d}<0[/tex].

The test statistic value is, t = -5.053.

The degrees of freedom is, 16.

Compute the p-value as follows:

[tex]p-value=P(t_{16}<-5.053)=0.000059[/tex]

Thus, the range consisting of the p-value is, 0.000001 < p-value < 0.00001.

Answer:

Below in bold.

Step-by-step explanation:

(a) y=x^2sin2x

Using the Product Rule:

dy/dx = x^2*2cos2x + 2xsin2x

dy/dx = 2x(xcos2x + sin2x).

(b) y=ln sqrt(1+t^2)

     y = ln (1 + t^2)^1/2

Using the chain rule:

dy/dx =  1 / (1 + t^2)^1/2 * 1/2(1 + t^2)^-1/2 * 2t

=  2t/(1 + t^2)^1/2 * 1/ (2(1 + t^2)^1/2

=   2t / 2(1 + t^2)

= t / ( 1 + t^2).

Hello.

In order to convert this equation into slope intercept form, we need to divide the entire equation by 7:

[tex]\tt{8x-7y=13[/tex]

[tex]\tt{\displaystyle\frac{8x}{7} -\frac{7y}{7}=\frac{13}{7}[/tex]

Simplify:

[tex]\tt{\displaystyle\frac{8x}{7}-y=\frac{13}{7}[/tex]

Add y to both sides:

[tex]\Large\boxed{\sf{y=\displaystyle\frac{8x}{7} -\frac{13}{7}}}[/tex]

I hope it helps.

Have an outstanding day. :)

[tex]\boxed{imperturbability}[/tex]

Hey there!

8x - 7y = 13

8x - 13 = 7y

(8x - 13)/ 7 = y

8x/7 - 13/7 = y

Hope it helps ya!

Answer:

GH= 47

Step-by-step explanation:

[tex]2(3x - 4) = 9x - 59[/tex]

[tex]6x - 8 = 9x - 59[/tex]

[tex]6x - 9x = - 59 + 9[/tex]

[tex] \cfrac{ - 3x}{ - 3} = \cfrac{ - 51}{ - 3} [/tex]

[tex]x = 17[/tex]

[tex]gh = 3(17) - 4[/tex]

[tex]51 - 4[/tex]

[tex] = 47[/tex]

Answer:

Final Exam score is the response variable.

Step-by-step explanation:

The response variable is the variable of interest. It is what is being tested for given the predictor variables. The response variable is also called the dependent variable and from our question we want to predict final exam scores would improve if attendance is made mandatory or as the question says, required. The number of times attended is the independent variable while final exam score is the response variable.

[tex]\underline{\underline{\large\bf{Solution:-}}}\\[/tex]

The standard form of a line is given by -

[tex]\green{ \underline { \boxed{ \sf{Ax+By=C}}}}[/tex]

where

[tex]\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} -1 \\\end{gathered} [/tex]

Arranging equation in standard form -

[tex]\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} - \frac{1}{1} \quad (1 = \frac{1}{1})\\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} - \frac{1 \times 4}{1 \times 4} \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \sf y = -\frac{5x}{4} - \frac{4}{4} \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \sf y = \frac{-5x-4}{4} \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \sf 4y = -5x-4 \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \sf 4y +5x =-4 \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \sf 5x +4y=-4 \\\end{gathered} [/tex]

Comparing with standard form of line -

Thus , 5 is our required answer.
