If the one side of the smaller polygon is 2 and the same side of the larger polygon is 5, than there is a ratio of 2 1/2. Meaning, that since the area of the small polygon is 20, the area of the larger polygon must be 50.

Reason:

20 x 2 1/2

20 + 20 + 10 = 50

Answer:

C) 50

Let me know if I'm wrong. I did the math in my head, so I'm not 100% positive. Sorry if this doesn't help :(

Find the first six terms of the sequence. a1=-7, an=2*an-1
AlladinOne [14]
The first term of the sequence is a_{1} = -7 . 

The sequences is recursive, every next term of the sequence is obtained by multiplying the previous term by 2.

So, we can find the next 6 terms as shown below:

a_{2} = 2*a_{1}=2(-7)=-14 
a_{3} = 2(-14)=-28 
a_{4} = 2(-28)=-56 
a_{5} = 2(-56)=-112 
a_{6} = 2(-112)=-224 
a_{7} = 2(-224)=-448

Charlie is at an amusement park that has 18 different rides. Each ride costs $1.75. The function C(r) = 1.75r represents the tot
sleet_krkn [62]
Domain= [0,18], Range = [0,31.50]
If Charlie will only go to a single ride one time the possible rides he could go on would be 0 rides to all 18 rides for a domain of [0,18]. The output of the maximum and minimum x values would give us 0 dollars for riding 0 rides and 31.50 for riding all 18 (1.75 *0 = 0) and (1.75*18 = 31.50) so the range is [0, 31.50]

Question 5
navik [9.2K]

Answer:

A. Similar using SAS; ∆ABC ~ ∆DFE

Step-by-step explanation:

m<B of ∆ABC = m<F of ∆DFE

AB corresponds to DF

AB/DF = 12/8 = 3/2

BC corresponds to FE

BC/FE = 24/16 = 3/2

Thus, the ratio of the corresponding sides of both triangles are the same. Therefore, both triangles has two sides that are proportional to each other, and also had an included corresponding angles that are congruent to each other.

By the SAS criterion, we can conclude that both triangles are similar to each other. That is, ∆ABC ~ ∆DFE
