The drawbridge will be at an incline of 10.56 degrees. That is 5.56 degrees more than it's initial incline of 5 degrees.

If you draw a picture of this situation, you will see that you can write a sine ratio with the 11 and 60 (opposite over hypotenuse)

sin(x) = 11/60  Solve the equation for x

x = 10.56

HELP HELP HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Arrange the functions in ascending order, starting with the function t
san4es73 [151]
If x is squared, that will be biggest by the end because it gets bigger the quickest. x^2 + 4 is always 4 greater than x^2, no matter what the value of x is.

5x+3 is always 3 greater than 5x also.

Besides that, you can rank them based on their slopes (5x < 7x < 8x, etc.)

So,
5x
5x + 3
7x
8x + 3
x^2
x^2 + 4

You can also just say “eventually” means that they’re asking to find the values of each when x is really big. so just choose x=100, and plug that into each one.

So, to check that order:
5(100) = 500
5(100) + 3 = 503
7(100) = 700
8(100) + 3 = 803
(100)^2 = 10,000
(100)^2 + 4 = 10,004

Those are in ascending order, so that must be the right order!

Answer:

Slope of line is \pi

Step-by-step explanation:

Given that the company logo has four concentric circles.

To plot the line on the graph take point as ( Diameter, Circumference )

Circumference of a circle is given by C=\pi D

Where D is the diameter.

To draw a line, we need at least two-point.

Now,

Take D=1

Circumference of a circle will be C=\pi D=\pi

Required point is (1,\pi)

Take D=0

Circumference of a circle will be C=\pi D=0 \pi

Required point is (0,0)

The slope of line is given by s=\frac{Y2-Y1}{X2-X1}

Hence,

s=\frac{Y2-Y1}{X2-X1}

s=\frac{0-[tex]\pi}{0-1}[/tex]

s=\frac{[tex]\pi}{1}[/tex]

s=\pi

Thus, Slope of line is \pi

{(2,5),(7,3)} is the inverse relation of the function {(5,2),(3,7)} truth or false
dezoksy [38]

frankly yes, because when you want inverse a function you must inverse it with line x=y

so when you inverse a function Df and Rf will convert together!

Answer:

P(Kritika)= 27/41

P(Gavin)=1-(27/41)

= (41-27)/41

=14/41
