You're looking for an inequality of the form |t-b|\le a, or -a\le t-b\le a, or b-a\le t\le b+a.

Start with

350^\circ\le t\le400^\circ

Notice that 375º is the midpoint of this interval of temperatures. If we subtract all sides by 375º, then we get

-25^\circ\le t-375^\circ\le25^\circ

so we can set a=25^\circ and b=375^\circ, and we can rewrite this inequality in terms of absolute values as

|t-375^\circ|\le25^\circ

Answer:                                            

p(x)=x^3-4x^2+5x-2

=(2)^3-4(2)^2+5(2)-2

=8-4(4)+10-2

=8-16+10-2

=0

Parallelogram ABCD has vertex coordinates a(0,2) b (6,2) c (8,6 and d (2,6) write a rule to find the vertex coordinates of a par
Anastasy [175]

Answer:  The rule is explained.


Step-by-step explanation:  As shown in the attached figure, ABCD is a parallelogram with vertices A(0,2), B(6,2), C(8,6) and D(2,6).

Suppose, we are to find the vertices of a parallelogram PQRS that is smaller than but similar to ABCD, then we can follow the following rule.

Let us consider a positive real number k. Then the new coordinates of smaller and similar parallelogram PQRS will be

Co-ordinates of P will be (k,2+k),

Co-ordinates of Q will be (6-k,2+k),

Co-ordinates of R will be (8-k,6-k)

and

co-ordinates of S will be (2+k,6-k).

Taking any positive real value of k, we will get a new, smaller parallelogram which will be similar to ABCD.
