Factor x^2-10x+25,please show work

Mathematics
1 answer:
Papessa [141]4 years ago
5 0
This is relatively easy because that 25 is a perfect square, whose (square) roots are 5 and -5.  x^2-10x+25 = (x - 5)(x - 5).  Note how (-5)(-5) = +25, and how -5x - 5x = -10x.

The roots are { (x-5), (x-5) }.

Which graph represents the solution to the system of inequalities?<br> x + y ≤ 4<br><br> y – x ≥ 1
frosja888 [35]

Given inequalities are

x+y\le4 and

y-x\ge1

Now we will graph both inequalities to get the common region which represents solution.

<u>Work for x+y\le4 </u>

first we graph the line x+y=4 then shade the graph for inequality symbol \le

we can plug any random number for x and find y-value to get points

lets plug x=0 then we get:

x+y=4

0+y=4

y=4

so the point is (0,4)

Similarly we can find more point like (4,0).

Now graph both points and join both points by straight line.

Now we find direction of shading.

pick any test point which is not on that line x+y=4 say (0,0)

and plug it into orinal inequality x+y\le4

0+0\le4

0\le4

which is true.

True means shade in direction of test point. Otherwise we shade in opposite direction.

We will repeat same process for other inequality to graph that.

Hence final graph for the answer will be as shown in attached image.

Triangular region ABC is final answer.

OleMash [197]

Answer:

diamerer of the hair (t)  3.11 X 10^{-5} m

Step-by-step explanation:

The first dark spot is at the zero location where the glass plates touch. To find the number of dark fringes after first dark fringe, divide 12 cm by 0.75 mm (.075 cm)

12/.075 = 160.0

total number of additional bright fringe is 156 because there is no further portion for extra dark fringe.

diamerer of the hair (t) can be derived as

2nt = (m + .5)*wavelength

2(1.52)(t) = (160.5)(589.3 X 10^{-9})

t = 3.11 X 10^{-5} m
