Which shows the most likely side lengths for a parallelogram

Mathematics
1 answer:
Fed [463]3 years ago
5 0

Answer:

The correct option is (D).

Step-by-step explanation:

A quadrilateral is a parallelogram if the following conditions are met:

  • If two pairs of opposites are equal in length.
  • If two opposite sides are parallel to each other and are equal.
  • If the diagonals bisect each other in equal halves.

So, for a parallelogram the opposite sides are equivalent in length.

From the provided length of 4 sides of a quadrilateral, consider the sides provided by option D.

4, 9, 9, 4

Two sides are of length 4 units and two of 9 units.

According to condition 1, the sides {4, 9, 9, 4} can form a parallelogram.

Thus, the correct option is (D).

The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h. A=(a+b)/2 h Solve for a.
yKpoI14uk [10]

Answer:

a=\frac{2A}{h}-b

Step-by-step explanation:

Hello, I think I can help you with this.

According to the information provided in the problem, the area of ​​a trapezoid is given by

A=\frac{a+b}{2} *h\\

Step 1

solve for a, it means isolate a

A=\frac{a+b}{2} *h\\divide\ both\ sides\ by\ h\\\\\frac{A}{h}= \frac{\frac{a+b}{2} *h}{h} \\\frac{A}{h}=\frac{a+b}{2}\\\\Now, multiply\ both\ sides\ by\ two\\\\ 2*\frac{A}{h}=2*\frac{a+b}{2}\\2*\frac{A}{h}=a+b\\\frac{2A}{h}=a+b\\\\subtract\ b\ for\ both\ sides\\\frac{2A}{h}-b=a+b-b\\a=\frac{2A}{h}-b

Have a good day.

Find the equation of the tangent line to the curve y=2sinx
Mrrafil [7]
 Hello
f(x) = 2sin(x)
f(<span>π/6) = 1 
f'(x) 2cos(x)
f'(</span>π/6) = 2×co(π/6) = 2 × root(3)×0.5  =root(3)
The equation of this tangent line is : y= root(3)(x-π/6)+1
y = root(3)x+1 - π/6(root(x))  <span>in the form y=mx+b
m = root(3)   and   b = </span>1 - π/6(root(x))
