It is not a function
bixtya [17]2 years ago
5 0

Step-by-step explanation:

1. Vertical Line Test: By definition a function can only output 1 value for each unique input. So if I were to put a vertical line on a graph it should only intersect one point, if it intersects two, that would mean there is 2 outputs for 1 input, so it's not a function

2: Term

3: Sequence: I don't really know how to explain this besides it's literally the definition

4: Relation: This can also be a function, but it it doesn't pass the vertical line test, it's just a relation

5: Solution: A solution to an equation is just what value makes an equation true (both sides equal)

6: Variable: The value varies, it can be anything, depending on what the equation is, so for example y=mx+b, the value of y varies depending on the value of x (and also m and b obviously, but those are constants)

A sector with an area of 30(pi) cm^2 has a radius of 10 cm.
Karolina [17]

Answer:

  108°

Step-by-step explanation:

The area of a sector is given by the formula ...

  A = (1/2)r²θ . . . . . where θ is in radians

Solving for θ, we find ...

  θ = 2A/r²

For your given sector, the central angle is ...

  θ = 2(30π cm²)/(10 cm)² = 0.6π . . . . radians

π radians is 180°, so the central angle in degrees is ...

  θ = (0.6)(180°) = 108°

The central angle measure of the sector is 108°.

What is the equation and the answer?
Nastasia [14]

Answer:

30

Step-by-step explanation:

So we begin by assigning variables to each side with:

DE = x

EF = y

DF = z

Now we start listing a system of equations from what is given:

x+y+z=81

x=2y

x-4=z

Once we solve that with substitution, we get the result of:

x=34

y=17

z=30.

Since z is the length of DF, the length of DF is 30.

I hope this helped! :D
