Answer: 21.994 cm²
Step-by-step explanation:
Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.
Formula for finding area of a circle = πr² where π is a constants . It has value of 22/7 or 3.142
Now area of the bigger circle = 3.142 x 3²
= 3.142 x 9
= 28.278 cm² Now are of the two smaller triangle = 3.142 x 1² x 2
= 6.284 cm².
Therefore are of the shaded region = 28.278 - 6.284
= 21.994 cm²
Answer: y = -5x+5
Step-by-step explanation: Slope intercept form is written as y = mx+b where m is the slope of the function and b is the y-intercept of the function. In this linear function, the line crosses the y-axis at (0,5). This is the y-intercept. We can find the slope with the (y2 - y1) / (x2 - x1) by choosing 2 points on the graph. I chose (0,5) and (1,0). If you use the formula, you will end up with -5 as your slope.
(-7x)(9-2x)
-63x+14x
-49x is the answer
The answer is D :)
-4(-1)+2
4+2=
8
