Answer:
4, (31 +48), (31+66)
4, 79, 97
Step-by-step explanation:
4 + (x + 48) + (x + 66) = 180 ( sum of angles in a triangle)
4 + 48 + 66 + x + x = 180
118 + 2x = 180
2x = 180 -118
2x = 62
x = 62/2 = 31
Answer with explanation:
When point (x,y) in two dimensional plane is converted to polar plane,that is in terms of (r,α)
1. Origin (0,0)→Pole
2. x=0,y=0 becomes can be written as→ equation of polar axis,which is equal to 0.
the two curves drawn here has following line of symmetry
1. Symmetry along four lines of blade shaped curve,one along polar axis that is x=0,y=0 and two along,x=y and y=-x.
2. The curve which is in the shape of Cardioid has 1 line of symmetry that is , x=0.
The features which are present in the polar graph
Option:
A. Symmetry about the line
B. Symmetry about the polar axis = 0
Answer: The value of absorbance is 0.3010
Step-by-step explanation:
Transmittance,(T)= 50%
Absorbance, (A)= ?

Transmittance and absorbance are inversely related:

Hence,the value of absorbance is 0.3010 when transmittance was 50%.
Answer:
Answer is at the bottom!!
Step-by-step explanation:
y = - \frac{2}{5} x - 2
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 5y = 10 into this form
subtract 2x from both sides
5y = - 2x + 10 ( divide all terms by 5 )
y = - \frac{2}{5} x + 2 ← point- slope form with slope m = - \frac{2}{5}
Parallel lines have equal slopes hence
y = - \frac{2}{5} x + c is the partial equation of the parallel line
to find c, substitute ( 5, - 4 ) into the partial equation
- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2
y = - \frac{2}{5} x - 2 ← equation of parallel line
Hope this helps!!
