Slope intercept form is y=mx+b
y= m or 2 because that is your slope but now all you need to is find your begin or find the point (3,7) on the graph.
f(5) means to replace the x in the equation with 5.
f(5) = 8(5) - 3
f(5) = 40 - 3
f(5) = 37
Answer: Area of sidewalk is 217m²
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle
π is a constant whose value is 3.14
A circular flower bed is 20 meters in diameter.
radius = diameter/2 = 20/2 = 10 meters
Area of the flower bed = 3.14 × 10²
= 314m²
The circular flower bed has a circular sidewalk around it that is 3 meters wide. This means that the total diameter would be
3 + 20 + 3 = 26m
Radius = 26!2 = 13m
Total area = 3.14 × 13² = 530.66m²
Therefore, area of the sidewalk is
530.66 - 314 = 216.66
The area of sidewalk is 217m² to the nearest whole number
Answer:
Step-by-step explanation:
A+B+C+D=360
A=180 as it half of the circle
B+C+D=180
60+C+90=180
150+C=180
C=180-150=30
The fraction of the circle to region C
30/180=1/6
So we'll assume the number is x.
So,
15+
= 9.
Now, we solve for x:
= 9-15
= -6
x = -6*2
x = -12
Check work:
15+
= 9
15+(-6) = 9
15-6 = 9
9 = 9
