Answer:

  A: a = 100

  B: b = 2

Step-by-step explanation:

The problem statement tells you that the population of bacteria is 100 at the start of our observation.

  t = 0, f(t) = f(0) = 100

If you remember that a 0 exponent means the value is 1, then you know ...

  f(0) = a·b^0 = a·1 = a

Since f(0) = 100, we know a = 100.

__

An exponent signifies repeated multiplication.

We know the population at t=0 is 100. At t = 1, we are told the population doubles. That means it is multiplied by 2.

 f(1) = 100·b^1 = 100·2

  b^1 = 2 . . . . . . . . . . . . . . . matching parts of these expressions

  b = 2 . . . . . . . . . . . . . because b^1 = b

What are similar triangles?

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be represented as ΔABC

Let the second triangle be represented as ΔEAD

Now , the measure of side AC = 4.8

The measure of side BA = 3.1

And , the measure of side EA = 4.8

The measure of side DA = 3.1

And , Corresponding sides of similar triangles are in the same ratio

So , the triangles ΔABC and ΔEAD are similar

Therefore , the angles will also be congruent

The measure of ∠ACB = The measure of ∠DEA = x°

The measure of ∠DEA = 180° - ( 53° + 86° )  ( angles of a triangle = 180° )

On simplifying the equation , we get

The measure of ∠DEA = 41°

Hence , the measure of x = 41° and they are similar triangles

In △ABC, G is the centroid and BE = 21. Find BG and GE.

Answers

Answer:

BG = 7, GE = 14

Step-by-step explanation:

The centroid is the intercession of medians.

The centroid theorem states that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.

BE is the median and point G is 2/3 of the distance from E:

GE = 2/3BE = 2/3(21) = 14

Then BG is:

BG = BE - GE = 21 - 14 = 7

The answer is BG = 7, GE = 14

Answer:

the answer is BG=7,GE=14

Answers

Answer:

$38250

Step-by-step explanation:

Given data

P= $340,000

t= 30-year,

r1= 6.475%

r2= 6.85%

For r1

A= P(1+rt)

A= 340,000(1+0.06475*30)

A= 340,000(1+1.9425)

A= 340,000*2.9425

A= $1000450

For r2

A= P(1+rt)

A= 340,000(1+0.0685*30)

A= 340,000(1+2.055)

A= 340,000*3.055

A= $1038700
