Answer:
y=-3/2x+1
Step-by-step explanation:
To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:
Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y--2)=-3/2(x-2)
y+2=-3/2(x-2)
y+2=-3/2x+3
y=-3/2x+1
We have to identify the quadrilateral with no line of symmetry and have rotational symmetry.
Line of symmetry is the imaginary line which divide the given quadrilateral in two equal halves.
Rotational symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appear the same.
Parallelogram is a quadrilateral which has no line of symmetry as we can not draw any imaginary line which divides the parallelogram in two equal halves.
But Parallelogram has rotational symmetry as when a parallelogram is rotated around a center point (turned) a number of degrees and parallelogram appear the same.
Hence, Parallelogram is the quadrilateral.
Answer:
A
Step-by-step explanation:
please give me brainliest
3.
A = pi x r^2
48 = 3.141... x r^2
÷ by value of pi
15.278... = r^2
Square root the ans, to get r
Thus, R = 3.908..... So, radius is 3.9
2.
Circumference = pi x diameter
87. = 3.141... x d
÷ by value of pi
27.692............. = diameter
Radius is twice the diameter. So, divide diameter by 2 to find the radius.
27.692.....÷ 2 = 13.846...
Thus, radius is 13.8cm
Hope this helps!
Just use the distance formula.. (-3 - -4)squared + (-5 - 6)squared
