Answer:
y = [tex]\frac{2}{5}[/tex] x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 5, 2) and (x₂, y₂ ) = (0, 4) ← 2 points on the line
m = [tex]\frac{4-2}{0-(-5)}[/tex] = [tex]\frac{2}{0+5}[/tex] = [tex]\frac{2}{5}[/tex]
The line crosses the y- axis at (0, 4 ) ⇒ c = 4
y = [tex]\frac{2}{5}[/tex] x + 4 ← equation of line

To calculate the area of a triangle, multiply the height by the width aka the "base" then divide by 2.
In this case, the height is 13 and the width is 12.
[tex]S = \frac{height.width}{2} = \frac{13.12}{2} = 78[/tex].

find the area of the quadrilateral.
Answers
Step-by-step explanation:
the area of a triangle is baseline × height / 2.
we have 2 major triangles that define this quadrilateral :
A-D-B and C-D-B.
both triangles have the same baseline : M_D + M_B = 14 cm
what we need to do is get the 2 heights M_C and N_A.
N_A we know already : 8 cm
so,
area A-D-B = 14×8/2 = 14×4 = 56 cm²
M_C we get via Pythagoras of the right-angled triangle D-M-C :
D_C² = M_C² + M_D²
10² = M_C² + 6²
100 = M_C² + 36
64 = M_C²
M_C = 8 cm
so,
area C-D-B = 14×8/2 = 56 cm²
so, the total area of the quadrilateral is
56 + 56 = 112 cm²

An analysis of past maintenance costs indicates that maintenance cost is an average of $0.20 per machine-hour at an activity level of 10,000 machine-hours and $0.25 per machine-hour at an activity level of 8,000 machine-hours. If this activity is within the relevant range, what is the total expected maintenance cost if the activity level is 8,700 machine-hours?
Answers
Answer: $2000
Step-by-step explanation:
Variable cost = Change in cost ÷ Activity change
($2000 - $2000) ÷ (10000 - 8000) = $0
Fixed cost element = Final cost - Variable cost
$2000 - ($0.00 ×10000) = $2000
Therefore, the cost formula for total maintenance is $2000 plus $0 per hour
y = $2,000 + $0x
At a level of 8,700 machine-hours, the total cost is:
y = $2000 + ($0.00 ×8700) = $2000

Sin(x-y)+sin(x-y prove the identity
Answers
Step-by-step explanation:
[tex] \sin(x - y) + \sin(x + y) = 2 \sin(x) \cos(y) [/tex]
We use the sum and difference identities.
Remeber the sum difference identity is
[tex] \sin(x + y) = \sin(x) \cos(y) + \cos( x ) \sin(y) [/tex]
and
[tex] \sin(x - y) = \sin(x) \cos(y) - \sin(x) \cos(y) [/tex]
So we get
[tex] (\sin(x) \cos(y) - \sin(y) \cos(x) ) + \sin(x) \cos(y) + \sin(y) \cos(x) [/tex]
Combine like Terms.
[tex]2 \sin(x) \cos(y) = 2 \sin(x) \cos(y) [/tex]
