Given: PQ = RS; PQ|| RS
Prove: PQRS is a parallelogram

Answers

Answer:

If PQRS is a parallelogram, then — PQ ≅ — RS and — QR ≅— SP . If a quadrilateral is a parallelogram, then its opposite angles are congruent. If PQRS is a parallelogram, then ∠P ≅ ∠R and ∠Q ≅ ∠S.

PQ=RS and PQ||RS implies PQRS is a parallelogram by showing that the diagonals bisect each other at O.

What is a parallelogram?

A quadrilateral with opposite sides equal and parallel but the angles are not right angle is called parallelogram.

Given that PQ=RS and PQ||RS .

Draw the parallelogram PQRS as in figure

To prove: PQRS is a parallelogram.

Construction: Join PS and QS as diagonals.

From the ΔORS and ΔOPQ,

PQ=RS (Given)

∠SOR=∠POQ   (opposite angles)

∠PQO=∠OSR  (since PQ=RS and PR is a traversal)

∴ΔOQS≅ΔOPQ

Hence, Op=OR and OQ=OS

Therefore , the diagonal of quadrilateral PQRS bisects each other.

Hence the given quadrilateral PQRS is a parallelogram.

What you would do is:

Then, you add the common coefficients:

(-2, 18), (0.2). (4, 42)
Oy=-222 - 2x - 3
Oy=-3x2 + 2x - 2
Oy = 3x2 - 2x + 2
Oy=-2x2 + 3x + 2

Answers

Answer:

y=3x2−2x+2

Step-by-step explanation:

Standard form of equation of a parabola is [tex]y=ax^2+bx+c[/tex]

As it passes through points (−2,18), (0,2) and (4,42), each of these points satisfies the equation of parabola and hence

18=a⋅4+b⋅(−2)+c or 4a−2b+c=18 ........(A)

2=c ........(B)

and 42=a⋅16+b⋅4+c or 16a+4b+c=42 ........(C)

Now putting (B) in (A) and (C), we get

4a−2b=16 or 2a−b=8 and .........(1)

16a+4b=40 or 4a+b=10 .........(2)

Adding (1) and (2), we get 6a=18 or a=3

and hence b=2⋅3−8=−2

Hence equation of parabola is [tex]y=3x^2 -2x+2[/tex] and it appears as shown below

A new drill is used to dig a hole in the ground. At noon, the hole is 13.2 feet deep when the new drill is turned

on for the first time that day. At 2 p.m., the drill has dug the hole to be 42 1/4 feet deep. The new drill dug

1.5 times as much of the hole as the old drill would have in the same length of time.

(a) What expression represents the number of feet the new drill dug?

(b) How many feet would the old drill have dug in the same length of time? Show your work. Answer the
question in a complete sentence.

Answers

Answer:

(a) 42.25 - 13.2

(b)  The old drill would have dug 19.367 ft in the same length of time (2 hours).

Step-by-step explanation:

(a) In the two hours, 12 Noon to 2 p.m., the new drill dug

42.25 - 13.2 =

29.05 feet.  

(b) Let r = the old drill dig rate in units of ft/hour

Then, 1.5r = the new drill dig rate.

So, 1.5r (2 hours) = 29.05, so that

r = (29.05)/(1.5 * 2) = 9.6833333 ... ft/hour.

So, the answer is: 9.683333 ... * 2 = 19.367 ft, rounded to the nearest 1000th.  Thus, the old drill would have dug 19.367 ft in the same length of time (2 hours).  

The required expression and the length of hole are 1.5( 42(¹/₄) - 13.2) and 43.57 feet respectively.

What is Unitary method?

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

The given problem can be solved by unitary method as follows,

(a) The expression that represents the length of hole dug by new drill is given as,

The length of hole dug by old drill in 2 hours is given as,

42(¹/₄) - 13.2

For new drill it is  1.5( 42(¹/₄) - 13.2) feet.

(b) The length of drill dug by old drill is,  

42(¹/₄) - 13.2

=  42.25 - 13.2

=  43.57 feet.

Hence, the expression for hole length by the new drill and the length of hole dug by old drill are given as  1.5( 42(¹/₄) - 13.2) and 43.57 feet respectively.

What is the smallest distance between the origin and a point on the graph of:y=1/sqrt(2)*(x^2-8)
