Polygon C and polygon D are similar. The perimeter of polygon C is 192 inches, and the perimeter of polygon D is 48 inches. If o
Marianna [84]

Answer:

B. 2 in.

Step-by-step explanation:

First, put the two perimeters together to form a fraction.

192/48, which can simplify to 4/1

Now, following the order in which you put the perimeters (I used C/D,) set it equal to the sides.

\frac{4}{1}  =  \frac{8}{x}

Now, cross multiply. (multiply 1 and 8, 4 and x.)

4x = 8

Now, solve.

x=2 inches.

Need help, please I can’t get these wrong!
algol13

Answer:

1: 119   2: 61   3: 61   4: 119   5: 119   6: 61   7: 61  

Step-by-step explanation:

Since we know that m & n are parallel we can prove which angles are congruent to angle 8 and which are supplementary

5: 119 (vertical to angle 8)

1: 119 (corresponding angles theorem

2: 61 (linear pair)

3: 61 (vertical to 2)

4: 119 (vertical to 1)

6: 61 (same sided interior angles theorem)

7: 61 (corresponding)

Analyzing a Graph In Exercise, analyze and sketch the graph of the function. Lable any relative extrema, points of inflection, a
tigry1 [53]

Answer:

x=1 is the minima

No point of inflection

y axis is asymptote

Step-by-step explanation:

A function is given by

y=x-lnx

Let us use derivatives to find extrema point of intersection etc

y' = 1-1/x\\y"=1/x^2\\y"' = 2/x^3

We find that second derivative cannot be equal to 0 for any value of x.

Hence there are no points of inflection.

Equate I derivative to 0

x =1

At x=1 I derivative is 0 and II derivative positive. So minima at x=1 and y =1

ln x is not defined for 0 or negative values of x

Hence asymptote is x=0 or y axis

Domain is (0,infty)

Range is (1,infty)

Since I derivative is negative for x <1 and positive for x>1

decreasing in (0,1) and increasing in (1,infty)
