Answer/Step-by-step explanation:
3. Function: NO
Justification: there will be more than one y-value/output related to one x-value/input.
4. Function: YES
Justification: There are exactly one y-value/output related to each input/x-value in the relation.
5. Function: YES
Justification: each x-value/input is mapped to exactly one y-value/output. No input value is mapped to more than one output value.
Answer:
275=25(6+x) and he mowed 6 lawns and got $150 and he walked 5 dogs and got $125
Step-by-step explanation:
6*25=150
275-150=125
125/25=5
The standard form of hyperbola is:
(x-h)²/a²-(y-k)²/b²=1
center:(4,5)
Length of the horizontal transverse axis: 8-5=3=2a
thus
a=3/2
a²=9/4
b=2
b²=4
Hence the equation will be:
(x-4)²/(9/4)-(y-5)²/4=1
simplifying this we get:
[4(x-4)²]/9-(y-5)²/4=1
Answer:
C.52 square units
Step-by-step explanation:
We are given that
Length of cross-section ADGF,l=13units
Length of cross-section ADGF, b=4 units
We have to find the area of cross-section ADGF of this right rectangular prism.
We know that
Area of rectangle=
Using the formula
Area of cross-section ADGF of this right rectangular prism
=
Area of cross-section ADGF of this right rectangular prism=52square units
Option C is correct.
C.52 square units
