Answer:

45 degrees

Step-by-step explanation:

Answer:

b =45

Step-by-step explanation:

A full circle is 360 degrees

b+315 = 360

Subtract 315 from each side

b+315-315 = 360-315

b =45

Graph the inverse of the function.
Ghella [55]

Answer:

The graph of the inverse function is the same that the graph of the original function

Step-by-step explanation:

step 1

Find the equation of the function in the graph

Let

f(x) ---> the function in the graph

we know that

Is a linear function

take the points (0,6) and (6,0)

<em>Find the slope of the linear function</em>

m=(0-6)/(6-0)\\m=-1

<em>Find the the equation of the linear function in slope intercept form</em>

f(x)=mx+b

we have

m=-1

b=6 ---> the y-intercept is given

substitute

f(x)=-x+6

step 2

Find the inverse of the function f(x)

Let

y=f(x)

y=-x+6

<em>Exchange the variables (x for y and y for x)</em>

x=-y+6

Isolate the variable y

y=-x+6

Let

f^{-1}(x)=y

f^{-1}(x)=-x+6

f^{-1}(x)=f(x)

In this problem the graph of the inverse function is the same that the graph of the original function

Urgent!!!! not worried about a but i need b and #4
Oksi-84 [34.3K]

b) The surface area is 564.5. Picture below.

4. Three possibilities.

Formula for volume of a cylinder: πr^2h

Formula for volume of sphere: 4/3πr^3

If the radius of the sphere is 1 inch than the volume is: 4.18879 or 4.19 rounded.

I used substitution on this website https://www.omnicalculator.com/math/volume

Just plug in the 4.18879 at the cylinder volume and put in a random number in the radius or height whichever you want then it'll give you the one you left blank. You'll find three possibilities for the radius and height of 4.18879 volume.

If cosa=1/2(a+1/a), verify that. cos2a=1/2(a²+1/a²)​
Alborosie

Answer:

see explanation

Step-by-step explanation:

using the identity

cos2a = 2cos²a - 1 , then

cos2a

= 2[ \frac{1}{2}(a  + \frac{1}{a}) ]² - 1

= 2 [ \frac{1}{4} (a² + \frac{1}{a^2} + 2) ] - 1

= \frac{1}{2} (a² + \frac{1}{a^2} ) + 1 - 1

= \frac{1}{2} (a² + \frac{1}{a^2} ) ← thus verified

Porque esos objetos tienen forma de esfera?​
Flura [38]

Answer:

following are the solution to the given question:

Step-by-step explanation:

It must get everything, or to at least little of it. Unless the shape of even a ball is modified into a square, for example, it simply will not work that form it is used, because it normally can't bounce or roll. There is no issue with other products if modified, for example in an application, as it is quadratic, it will function the same way.

Daniella is making 2/3 of a recipe. the full recipe calls for 3 1/2 cups of flour. how many cups of flour should Danielle use?
kupik [55]

2 \frac{1}{3} cups of flour

We require to find \frac{2}{3} of 3 \frac{1}{2}

change the mixed number to an improper fraction and of to multiply

3 \frac{1}{2} = \frac{7}{2}

\frac{2}{3} × \frac{7}{2}

= \frac{2(7)}{3(2)} = \frac{14}{6} = \frac{7}{3} = 2 \frac{1}{3}
