Answer: Polygons A and B are not Similar.

Polygons A and C are Not Similar.

Only Polygons B and C are Similar.


Step-by-step explanation:Answer:

We are given three rectangular figures A, B and C.

We need to determine which polygons are similar and which are not.

<em>Note: The sides of similar figures are in proportion.</em>


Let us check first A and B figures.

105/120 = 7/8

80/90 = 8/9.

We can see 105/120 ≠ 80/90

Sides are not in proportion of Polygons A and B.

So, the Polygons A and B are not Similar.


Let us check first A and C figures.

105/100 = 21/20

80/75 = 16/15.

We can see 105/100 ≠ 80/75

Sides are not in proportion of Polygons A and C.

So, the Polygons A and C are Not Similar.


Let us check first B and C figures.

120/100 = 6/5.

90/75 = 6/5.

We can see 120/100 = 90/75 = 6/5

<h3>Sides are in proportion of Polygons B and c.</h3><h3>So, the Polygons B and C are Similar.</h3>

the longer side / the shorter side must be the same for rectangles to be similar.

For  A:  105 / 80  =  1.32

For  B:  120 / 90  =  1.33

For  C:  100 / 75  =  1.47

 

So... only  A  and  B are similar.

If f (x) = 5 x minus 25 and g (x) = one-fifth x + 5, which expression could be used to verify g(x) is the inverse of f(x)?
Vinil7 [7]

Answer:

The expression used to represent g(x) as inverse of f(x) is \frac{1}{5}(5x-25)+5

Option B is correct.

Step-by-step explanation:

We are given:

f(x)= 5x-25\\g(x)=\frac{1}{5}x+5

We need to find the expression that could be used to verify g(x) is the inverse of f(x).

We know that g(f(x))=x is inverse of function

So placing value of f(x) in g(x)

g(f(x))=\frac{1}{5}(5x-25)+5

So, the expression used to represent g(x) as inverse of f(x) is \frac{1}{5}(5x-25)+5

Option B is correct.

We can also solve to prove that g(f(x))=x

g(f(x))=\frac{1}{5}(5x-25)+5\\g(f(x))=\frac{5}{5}(x-5)+5\\g(f(x))=x-5+5\\g(f(x))=x

Find the first four terms of the sequence given by the following an=57-4(n-1),n=1,2,3
Crazy boy [7]

Answer:

57, 53, 49, 45

Step-by-step explanation:

Substitute for the n for n=1,2,3,4 so the first term is 57-4(1-1) so =57-4(0) so

a(1) = 57-0 = 57  so that is the 1st term

2nd term 57-4(2-1) so =57-4(1) so   a(2) = 57-4 = 53, etc.

Brainleiest What is the unit rate for 692.08 ft in 21.1 s? Enter your answer, as a decimal, in the box. ft/s
ale4655 [162]

Answer:

Unit rate is 32.9561 feet per second.

Step-by-step explanation:

Unit rate is a number where one quantity is represented so that the other quantity is 1.

So we can give the unit rate of this as number of feet per 1 second.

It has traveled 692.08 ft in 21.1 seconds.

We have to find how many feet it travels in 1 second.

Unit rate = Number of feet / Number of seconds

=\frac{692.08feet}{21.1seconds}

=32.9561 feet per second
