A=π400
A=1256.637061
Area of triangle=(b*h) /2
A=(40*20)/2
A=800/2
A=400
Area of circle-area of triangle=area of shaded region
1256.637061-400=856.637061
Hope this helps!
Answer:
9.2 feet. b.)
Step-by-step explanation:
This uses the Pythagorean Theorem
Do you notice that the ladder forms a right triangle with the building.
10 feet = hypotenuse length
4 feet = bottom leg length
x feet = height of building
so 10^2 = 4^2 + x^2
100 = 16 + x^2
84 = x^2
x = root(84) = 9.16515 feet about 9.2 feet
Answer:
start where r is at, then go down 2 units to then to the right 2 times
Step-by-step explanation:
not sure but worth a try
Label your graph the horizontal line is “X” and the vertical line is Y”. the origin is always (0.0) which is where the two lines meat dead center of the graph. From the origin go to the left counting in negatives... 0,-1,-2,-3.... etc. do the same thing going towards the right but in positives, then go up from the origin counting in positives and then down from the origin in negatives like you did going left. OKAY now if a coordinate is (-3,6), -3 is your “X” and 6 is your “Y” so you would go left negative 3 on the X line (horizontal line) and once you get to negative 3 you go UP 6. There is your first coordinate plotted on your graph
y - x = 1.
or, y= 1+x
y - 2x = 3.
=>1+x -2x= 3 (substituting the value of y)
=>-x= 2
=>x= -2
y = -2+1 = -1
Therefore, x = -2 and y = -1
