Answer: 12.56 km

Step-by-step explanation:

C=2(3.14)r

C=2(3.14)2

C=12.56

Step-by-step explanation:

3. Let us take apart the right side

1+cos2x = 1 + cos^2x - sin^2x

1 - sin^2x = cos^2x

therefore we have 2cos^2x

Therefore we just have cos^2x/cos^2y = 2cos^2x/2cos^2y, which is true.

4. tan(x/2) = +/- sqrt((1-cosx)/(1+cosx)) using half angle identities for sin and cos.

Therefore tan^2(x/2) = (1-cosx)/(1+cosx)

If we multiply top and bottom by tanx, we get

(tanx - sinx)/(tanx + sinx), which is the right side.

The answer should be 126 or A.

Answer:(x - 2) (x + 3) ⋅  2x (x + 2)

Step-by-step explanation: factor the polynomial

Given :

A curve : 3x² - 2xy + y² = 11

To Find :

The slope of the line tangent to the curve 3x^2-2xy+y^2=11 at the point (1, -2).

Solution :

Differentiating given curve w.r.t x is :

6x - ( 2y + 2xy' ) + 2yy' = 11

Putting the point ( 1, -2) in above equation, we get :

6 - ( 2(-2) + 2y' ) - 4y' = 11

6 - ( -4 + 2y' ) - 4y' = 11

10 - 6y' = 11

6y' = -1

[tex]y' =\dfrac{-1}{6}[/tex]

Therefore, the slope of the line tangent to the given point is [tex]y' =\dfrac{-1}{6}[/tex] .

Answer:

5/3

Step-by-step explanation:

The previous explanation was incorrect because they forgot to differentiate the other side of the equation (11), which would actually become 0, and make the answer 5/3

Answer:

B

Step-by-step explanation:

Use the pythagorean theorem to find the hypotenuse. You can do this by squaring 12 and 11 (separately) and then adding those together. You'll get 265. However, since this is c squared and not c, you have to find the square root for the correct answer. The square root of 265 is approximately 16.28. Hope this helps!

Crew because 23>8 23 is larger than 8

Magnitude=A great size, or extent of something

Given:

The function is [tex]f(x)=3.5x^3[/tex].

To find:

Whether the given function is Steeper, Less steep, or Reflected over the x-axis to describe the other function.

Solution:

Transformation of function: If f(x) is function and

[tex]g(x)=a\ f(x)[/tex]

Here, a is vertical stretch or compression.

If 0<|a|<1, then g(x) is less steeper than f(x) because f(x) is vertically compressed.

If |a|>1, then g(x) is steeper than f(x) because f(x) is vertically stretched.

If a is negative, the f(x) is reflected over the x-axis, to get g(x).

On comparing the function [tex]p(x)=4.5x^3[/tex] with [tex]f(x)=3.5x^3[/tex], we get 4.5>3.5 So, it is the case vertical stretched and p(x) is steeper than f(x).

On comparing the function [tex]q(x)=-x^3[/tex] with [tex]f(x)=3.5x^3[/tex], we get |-1|=1<3.5 So, it is the case  vertical compression and q(x) is less steeper than f(x) and because of negative sign the function is reflected over axis.

On comparing the function [tex]r(x)=3x^3[/tex] with [tex]f(x)=3.5x^3[/tex], we get 3<3.5 So, it is the case vertical compression and r(x) is less steeper than f(x).

Therefore, [tex]p(x)=4.5x^3[/tex]  is steeper.

[tex]q(x)=-x^3[/tex] is less steep and reflected over the x-axis.

[tex]r(x)=3x^3[/tex] is less steep.

Answer: 58

Step-by-step explanation: can't really explain, but I promise that's right

Answer:

58 is a reasonable estimate for the number of students wearing glasses.

Step-by-step explanation:

20% of 290 ( or 290*0.2) is equal to 58.

Therefore, the answer is 58.

Answer:

AB = 5√2

AC = √145

BC = √65

Step-by-step explanation:

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

For AB A(-3,6),B(2,1),

AB = √(2+3)²+(1-6)²

AB = √(5)²+(-5)²

AB = √25+25

AB =  √50

AB = 5√2

For AC A(-3,6) and C(9,5)

AC = √(9+3)²+(5-6)²

AC = √(12)²+(-1)²

AC = √144+1

AC = √145

For BC B(2,1), and C(9,5)

BC = √(9-2)²+(5-1)²

BC = √(7)²+(4)²

BC = √49+16

BC = √65

Since All the sides are difference, hence triangle ABC is a scalene triangle

Answer:

Sophia gets 7,150

Step-by-step explanation:

9514 1404 393

Answer:

  no

Step-by-step explanation:

The percent symbol (%) is a shorthand way to write "divided by 100" (/100). The percent can be changed to a decimal by making that substitution.

  8% = 8/100 = 0.08

  80% = 80/100 = 0.80

  800% = 800/100 = 8.00

Effectively, the change to a decimal is made by moving the decimal point two places to the left. Richard's strategy only works if the percentage has 2 digits left of its decimal point. It does not work in the general case.
