Question: State whether each table of values represents a function
Answer:
Please check the explanation.
Step-by-step explanation:
As we know that the values in the table represent a function only if there there is only 1 input for every output.
Given the table 1
x y
-12 2
-10 10
0 -2
5 -6
8 -11
15 -15
From the table, it is clear that for each input there exists a unique output.
i.e.
According to the given table,
y = 2 at x=-12
y = 10 at x=-1 0
y = -1 at x=0
y = -11 at x=8
y = -15 at x=15
From the table, it is clear that for each input x, it has a unique output y.
Hence, table 1 is a function.
Given the table 2
x y
9 -18
-20 0
-6 1
-17 16
9 17
11 19
This table does not produce a function, because the input x=9 produces two outputs.
i.e.
at x = 9, the y = -18
at x = 9, the y = 17
Therefore, the table 2 does not represent a function.
and that i need answers please
Answer:
y=29
Step-by-step explanation:
Answer:
y=29
Step-by-step explanation:
We move all terms to the left:
58/y-(2)=0
The domain of the equation: y!=0
y∈R
We multiply all the terms by the denominator
-2*y+58=0
We add all the numbers together, and all the variables
-2y+58=0
We move all terms containing y to the left, all other terms to the right
-2y=-58
y=-58/-2
y=29

6 - 8x = 5x - 10x + 12
Please help I suck at math thank you
Answer:
I guess it's -2
Step-by-step explanation:
6-8x = 5x - 10x + 12
∴ 10x - 8x - 5x = 12 - 6
∴ 10x- 13x = 6
∴ - 3x = 6
∴ x = -6\3
∴ x = -2
Answer:
-2
Step-by-step explanation:
6-8x=5x-10x+12
5x-10x=-5x
=6-8x=-5x+12 MOVE -5x TO THE LEFT SIDE AND 6 TO THE RIGHT SIDE
= -8x+5x=12-6
= -3x=6
= -x=2
= x=-2

What is the perimeter of the triangle?
units
Answer:
Perimeter = 30
Step-by-step explanation:
hypotenuse = [tex]\sqrt{5^2+12^2}[/tex]
hypotenuse = [tex]\sqrt{25+144}[/tex]
hypotenuse = [tex]\sqrt{169}[/tex]
hypotenuse = 13
Perimeter = 5+12+13
Perimeter = 30

If the equation of motion of a particle is given by s = A cos(ωt + δ), the particle is said to undergo simple harmonic motion. (a) Find the velocity of the particle at time t. s'(t) = (b) When is the velocity 0? (Use n as the arbitrary integer.) t =
Answer:
a) the velocity of particle is -Aωsin (ωt + δ)
b) the velocity is zero when t = (nπ - δ) / ω, n ∈ Z
Step-by-step explanation:
Given that;
s = A cos(ωt + δ)
(a)
Find the velocity of the particle at time t
the velocity of the particle is given as; v = ds/dt
so differentiate s = A cos(ωt + δ) on both sides with respect to t
v = ds/dt = d/dt [ A cos(ωt + δ) ]
v = A d/dt cos(ωt + δ)
v = -Asin(ωt + δ) d/dt(ωt + δ)
v = -Aωsin (ωt + δ)
therefore, the velocity of particle is -Aωsin (ωt + δ)
b)
When is the velocity 0?
Now since the velocity will be zero; lets set v = 0
-Aωsin (ωt + δ) = 0
sin (ωt + δ) = 0
ωt + δ = nπ
ωt = nπ - δ
t = (nπ - δ) / ω, n ∈ Z
Therefore the velocity is zero when t = (nπ - δ) / ω, n ∈ Z

For each graph, describe the composition of transformations that maps ADEF
to ALMN.
Answer:
From the figure, it can be seen that ΔJ'K'L' is formed from ΔJKL by the rotation of ΔJKL by 90 degrees counter-clockwise.
It can also be seen that ΔJ"K"L" is obtained from ΔJ'K'L' by the refrection of ΔJ'K'L' across the x-axis.
Therefore, the rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is given by
