Answer:
The ratio of the area of triangle XBY to the area of triangle ABC is
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its areas is equal to the scale factor squared
In this problem
Triangles XBY and ABC are similar, because the corresponding internal angles are congruent
see the attached figure to better understand the problem
step 1
Find the scale factor
Let
z-------> the scale factor
we have
substitute
step 2
Find the ratio of the area of triangle XBY to the area of triangle ABC
Remember that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
we have
-----> scale factor
so
Answer:
The bacteria will grow from 1 to 1024 in 10 hours
Step-by-step explanation:
Given
P_0 = 1
P = 1024
We have to find time
Putting values in the formula
Anything multiplied with 1 remains the same
Using the property "when bases are same, the exponents can be put equivalent"
t = 10 hours
Therefore, the bacteria will grow from 1 to 1024 in 10 hours ..
