Answer:
y = 5x - 17
Step-by-step explanation:
y = mx + c
m = the gradient/slope = 5
y = 5x + c
Substitute (3, -2) into the equation above to find c.
-2 = 5(3) + c
-2 = 15 + c
-2 - 15 = c
-17 = c
y = 5x - 17

Answer:
• let's first get the percentage decrease:
• then multiply the percentage decrease with the mass given:
The area of the washer will be the area of the smaller circle SUBTRACTED from the area of the larger circle.
Area of a circle = pi * r^2 where r is your radius (which is half the diameter).
Larger circle area = pi *(diameter/2) ^2.
Smaller circle area = pi * (13.2/2)^2 = pi * 6.6^2 = 136.8484....
So...the area of the washer = larger circle area - 136.4848...
Answer:
51
Step-by-step explanation:
Hey There!
To find the perimeter of any figure all you have to do is add up all of the side lengths
5+5+7+11+7+16=53
so the perimeter is equal to 51
Note: the 18 is from the bottom length of the figure
you would have to add the 5 and 11
the extra seven is from the very right side length
