Given that ΔUVW is similar to ΔXYZ, find the length of ZX.
2 answers:
Answer:
D. 20
Step-by-step explanation:
We have been given that ΔUVW is similar to ΔXYZ and we are asked to find the length of ZX.
Since both triangles are similar, so their corresponding sides will be proportional. We will use proportions to solve our given problem as:
Now, we will multiply both sides of our equation by 5.
Therefore, the length of ZX is 20 units and option D is the correct choice.

The function represents exponential growth with the initial value equal to 1, the decay factor equal to 0.3, and the rate equal to 0.7.
<h3>Population Growth Equation</h3>
The formula for the Population Growth Equation is:
Pf= future population
Po=initial population
r=growth rate
t= time (years)
growth or decay factor = (1 ±r)
When 1+R > 1, the equation represents growth, while 1+R < 1 the equation represents decay.
The question gives:
, then
Pf=y
Po= 1
, thus
r= -70%= -0.7
decay factor= (1-0.7)=0.3
Therefore,
1+R will be = 1+(-0.7)=1 - 0.7 =0.3
When 1+R >1, the function represents exponential growth.
