You can find the x intercept of the equation by setting the value of y
to zero and solving the equation. Similarly you can solve the y
intercept by setting the value of x to zero and solving the equation.
Now while solving this rational function for intercepts if you face a
situation where the value in the denominator is zero it implies that
there is no intercept in that case as dividing something by zero is
indeterminate.
Slope = y2 - y1/x2 - x1
= -3 - (-1)/8 - (-2)
= -3 + 1/ 8 + 2
= -2/ 6
= - 1/3
hope this helps :)
Step-by-step explanation:
I just answered that. so, here again :
all we need to do is find the surface area, deduct windows and door areas.
that gives us the m² to be covered, which we have to multiply by $12.50 to get the total price.
the house surface area is like for a box, but we don't care about the top and the bottom. only about the walls.
the "box" is 18 m × 14 m × 4 m.
so, the front and the back walls are each
18m × 4 m = 72 m²
both front and back : 2×72 = 144 m²
each side wall is
14m × 4m = 56 m²
both sides : 2×56 = 112 m²
now for the deductions.
each window is
1.5 × 2 = 3 m²
both windows : 2×3 = 6 m²
the door is
1 × 2.5 = 2.5 m²
so, the total area to "side" is
144 + 112 - 6 - 2.5 = 247.5 m²
to side 247.5 m² it costs
247.5 × 12.5 = $3,093.75
Answer:
Step-by-step explanation:
<u>differentiating numerator wrt x :-</u>
(sinx)' = cos x
<u>differentiating denominator wrt x :- </u>
(1 + cos x)' = (cosx)' = - sinx
- Let's say the denominator was "v" and the numerator was "u"
here,
- since u is the numerator u= sinx and u = cos x
- v(denominator) = 1 + cos x; v' = - sinx
since cos²x + sin²x = 1
diving numerator and denominator by 1 + cos x
