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%.

those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below
that means, the squared variable is the "x", thus the form is

now, we know the vertex is at 0,1, and two x-intercepts of

thus

solve for "a", to see what that coefficient is, then plug it back in the vertex form equation
Take a picture of the problem and then ask your question
Answer:
-1
Step-by-step explanation:
We need two points to use the slope formula
(0,2) and (2,0) are points on the line
m= ( y2-y1)/(x2-x1)
= (0-2)/(2-0)
= -2/2
=-1
Answer:
171.06 cm²
Step-by-step explanation:
<u>First let us find the area of the circle</u>
Area = π r²
= π × 8 × 8
= π × 64
= 201.06 cm²
<u>Now let us find the area of parallelogram</u>
Area = Base × Height
= 6 cm × 5 cm
= 30 cm²
<u>And now we have to find the area of the shape when the parallelogram is cut from it</u>
<em>For that, you have to subtract the area of the parallelogram from the area of the circle.</em>
Let us solve now.
Area of the shape = Area of the circle - Area of the parallelogram
= 201.06 cm² - 30 cm²
= 171.06 cm²
