Answer:
see below
Step-by-step explanation:
1.)
(0, 4)
(1, 7)

y = 3x + b
(4) = 3(0) + b
b = 4
y = 3x + 4
Rate of change: 3 initial value: 4
2.)
(0, -5)
(1, -3)

y = 2x + b
(-5) = 2(0) + b
b = -5
Rate of change: 2 initial value: -5
Answer:
You should do this on your own but if you consider the way I graph it, the slope should be going downwards and in the middle of the graph, the y-intercept should be two units down. Each unit for the x line should be 14 units apart as stated in the function.

Answer:
57°
Step-by-step explanation:
∠LOM and ∠MON are complementary angles, so they add up to 90.
This means that:
3x-15 + 5x-23 = 90 =>
8x - 38 = 90 =>
x = 128/8 = 16
So m∠MON = 5*16 - 23 = 57°
Answer:
3p + 12
Step-by-step explanation:
5p -3p + 9 + p + 3
Move around the parts of the equation
5p -3p + p + 9 + 3
Add positive 9 to positive 3
5p -3p + p + 12
Add positive p to negative 3p
5p -2p + 12
Combine positive 5p and negative 2p together
3p + 12

Answer:
<u>Mass</u>

<u>Center of mass</u>
<em>Coordinate x</em>

<em>Coordinate y</em>

<em>Coordinate z</em>

Step-by-step explanation:
Let W be the wire. We can consider W=(x(t),y(t),z(t)) as a path given by the parametric functions
x(t) = t
y(t) = 4 cos(t)
z(t) = 4 sin(t)
for 0 ≤ t ≤ 2π
If D(x,y,z) is the density of W at a given point (x,y,z), the mass m would be the curve integral along the path W

The density D(x,y,z) is given by

on the other hand

and we have

The center of mass is the point 
where

We have

so
