What’s equivalent expressions to y(6+7)

Answer:I think it’s 7...

Step-by-step explanation:

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).

Answer:

yes 0.265 is correct it is your answer

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

-4(y + 6) + 5y

= -4y - 24 + 5y

= y - 24 (simplified)

Answer:

9y+24

Step-by-step explanation:

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

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:

-23

Step-by-step explanation:

I dont really know how to explain this sorry. but I hope it some what helps

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:

Step-by-step explanation:

Opposite angles of a rhombus are congruent, so [tex]6x+8=86 \longrightarrow x=13[/tex]

Also, adjacent angles of a rhombus are supplementary, so [tex]86+5z+4=86+7y+3=180 \longrightarrow y=13, z=18[/tex]

Step-by-step explanation:

there 16 apart from each other and simplyfy it you get a ratio of 3:5

Answer:

293 miles

Step-by-step explanation:

284.58-17.95=266.63

266.63/0.91=293

293 miles

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: $66.00

Step-by-step explanation: If every 1/6 is 1 dollar then that means a whole pie is 6 dollars

6 * 11 = 66

Answer:

2 ⅓  

Step-by-step explanation:

division is the same as a fraction

the dividend is the numerator and the divisor is the denominator

7÷3 is the same as 7/3

change 7/3 into a mixed number which is 2 ⅓  

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.

Answer:

What ever the length and width is you times them both I don't know if you exactly know that are now  but I think it is C

Hope it helps have a great day:)

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]

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. :)

Hey there!

8x - 7y = 13

8x - 13 = 7y

(8x - 13)/ 7 = y

8x/7 - 13/7 = y

Hope it helps ya!

Answer:

86 degrees

Step-by-step explanation:

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]
