Mathematics
1 answer:
klemol [59]3 years ago
3 0

Answer:

x = 4

Step-by-step explanation:

DE is similar to XY   and DF is similar to XZ

We can make proportions

DE                DF

------------ = ---------------

XY                  XZ

5               11

--------- = -------------

10             5x+2

Using cross products

5 (5x+2) = 10*11

Distribute the 5

25x+10 = 110

Subtract 10 from each side

25x+10-10 = 110-10

25x = 100

Divide by 25

25x/25 = 100/25

x = 4

HELP ASAP PLEASE!!!
nikklg [1K]

Answer:

Option C is correct.

Step-by-step explanation:

An exponential function is of the form:  y =a(b)^x ....[1] where a is the initial value, x is any real number and b is the growth factor  

Also, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).

Then, the growth "rate" (r) is determined as b = 1 + r.

and the decay "rate" (r) is determined as b = 1 - r

  • If b> 1, then it is exponential growth function.
  • if 0<b< 1. then it is exponential decay function.

Also, b = 1+ 4

Given the equation:  y = 50(1.15)^x

On comparing given equation  with [1] we get;

a = 50 and b = 1.15

Since, b = 1.15 > 1

Therefore, the given equation represents the exponential growth.

(A)

Yes, this y = 50(1.15)^x equation represents the exponential growth.

(B)

Initial value (a) = 50

(C)

Here growth factor, b = 1.15

and

1+ r = 1.15.

⇒r = 0.15\%
