Answer:

a) and c) - function,
b) and d) - nonfunction

Step-by-step explanation:

As per definition, a function is such a relationship that each input has exactly one output

Considering this we observe that:

a) function
b) not a function as input of -1 has two different outputs o and 1
c) function
d) not a function as input of 0 has two different outputs 0 and 0.5

I NEED HELP FAST! Find the measure of the missing angles.

loris [4]

Angle G = 130 degrees

Angle H = 50 degrees

Angle K = 74 degrees

Angle M = 106 degrees

Angle G would be 130 degrees because it's a vertical angle, and vertical angles are always alike.

Angle H would be 50 degrees because it's an adjacent angle, and we also know that one side of the line is always 180 degrees so we have an equation that looks like this 180 - 130 = 50 degrees

Angle K would be 74 degrees because it's a vertical angle.

Angle M would be 106 degrees because it's an adjacent angle.

The perimeter of a rectangular flower garden is 66m and its area is 272m^2. Find the length of the garden.

ExtremeBDS [4]

So we have lengths a and b and are given:

2a+2b = 66 => a+b = 33 => a= 33-b
a*b = 272

plug in one into the other:

(33-b)b = 272 => -b^2 +33b - 272 = 0

Can be factored as (b-16)(b-17) = 0, if you don't "see" this immediately, use the well known abc formula to find b.

So a=16 and b=17 or vice versa.

What are the solutions to. x^2 - x - 20 = 0

nignag [31]

Step-by-step explanation:

x² - x - 20 = 0

x² - (5-4) x - 20 = 0 

x² - 5x + 4x -20 = 0

x ( x - 5) + 4 ( x - 5) = 0

(x - 5) (x+ 4) = 0

Either. 

x - 5 = 0

x = 5

Or, 

x + 4 = 0 

x = -4

Five gal of water are added to a pool each minute.

fomenos

Simply divide 80 by 5. 5 goes into 80 16 times, and each 5 = one minuet, so it would take 16 minuets to fill the pool with 80 gallons.
