Area of a semicircle is 1/2* πr^2
Area of a square is s^2
Square’s area: 4mm^2
The radius is 3mm
Plug into the equation
1/2* π(3^2)
1/2* π(9)
We can use 3.14 as an estimate of pi
1/2*28.26
14.13mm^2
Now just add them both
Total area 18.13mm^2
The sin <ABC means that AC/AB. So we know AB=34. AC/AB=8/17. So the length of AC is 16. cos<ABC means BC/AB. tan<ABC means AC/BC.
Answer:
y = -2/3x - 11/3
Step-by-step explanation:
Answer:
y = -4x + 1
Step-by-step explanation:
you said, slope of -4, therefore it's -4x and you also said y intercept of 1, therefore it's a positive 1 : +1
combine them together: y = -4x +1
