I believe it should be 1.296 miles
Answer:
#1: 345
#2: 10%
#3: 7.35
#4: 290.50
Step-by-step explanation:
equation for the perpendicular Bisector of the line segment whose endpoints are (-9,-8) and (7,-4)
Perpendicular bisector lies at the midpoint of a line
Lets find mid point of (-9,-8) and (7,-4)
midpoint formula is
midpoint is (-1, -6)
Now find the slope of the given line
(-9,-8) and (7,-4)
Slope of perpendicular line is negative reciprocal of slope of given line
So slope of perpendicular line is -4
slope = -4 and midpoint is (-1,-6)
y - y1 = m(x-x1)
y - (-6) = -4(x-(-1))
y + 6 = -4(x+1)
y + 6 = -4x -4
Subtract 6 on both sides
y = -4x -4-6
y= -4x -10
equation for the perpendicular Bisector y = -4x - 10
Answer:
333cm^2
Step-by-step explanation:
Divide the compound shape into the two separate parts, the rectangle and the triangle.
The rectangle measuring 18cm by 14cm, getting the area, use the formula length*width. This is 18*14= 252cm^2.
Then the triangle has the height, 9cm and base 18cm, finding the area use the formula, 1/2*base*height.
1/2*9*18= 81cm^2.
Add the two, 252+81= 333cm^2.
Answer:64pi
Step-by-step explanation:
Circumference(c)=16pi
Circumference(c)=2 x pi x radius(r)
Substituting we get
16pi=2 x pi x r
Divide both sides by 2pi
16pi/2pi=(2xpixr)/2pi
8=r
Radius(r)=8cm
Area(a)=pi x r^2
a=pi x 8^2
a=64pi
Therefore area of the circle=64pi
