Answer:

1.4

Step-by-step explanation:

You can use a calculator or you can try it using this method:

4 * 0.05 = 0.2

4 * 0.3 = 1.2

1.2 + 0.2 = 1.4

Answer:

0.35*4=1.40

Step-by-step explanation:

Think of doing 35*4 but dividing the result by 100, or 2 decimal places to the left:

35*4 = 35*2*2 = 70*2 = 140

140/100 = 1.40

So, 0.35*4=1.40

<h2>Answer </h2>

.

f(100) = 498

.

<h2>Explain</h2>

.

f(2) = 8

f(3) = 13

.

<h3>Find b</h3>

3b - 2b = 13 - 8

b = 5

.

<h3>Find f(1)</h3>

f(1) = f(2) - b

f(1) = 8 - 5

f(1) = 3

.

<h3>Find f(100)</h3>

f (x)= f(1) + (x - 1)b

f(100) = 3 + (100 - 1)5

f(100) = 3 + (99)5

f(100) = 3 + 495

f(100) = 498

A line passes through the points A(n,4) and B(6,8) and is parallel to y=2x-5. What is the value of n?​
Lady_Fox [76]

The slope of <em>y</em> = 2<em>x</em> - 5 is 2. Parallel lines have the same slope, so the slope of the line through the given points <em>A</em> and <em>B</em> is also 2. This means

(8 - 4) / (6 - <em>n</em>) = 2

Solve for <em>n</em> :

4 / (6 - <em>n</em>) = 2

4/2 = 6 - <em>n</em>

2 = 6 - <em>n</em>

<em>n</em> = 6 - 2

<em>n</em> = 4

4x4+4x3-9x2-x+2 = x-1
dangina [55]

Answer:

x= 13/2

Step-by-step explanation:

multiply   4x4+4x3-9x2-x+2=x-1

calculate   16+12-18-x+2=x-1

move the terms   12-x=x-1

collect like terms calculate   -x-x=-1-12

divide both sides   -2x=-13

solution   x=13/2

Using the concept of a net rate introduced in Problem 2, determine a differential equation governing a population P(t) if the bi
Soloha48 [4]

We may be thinking about either of these choices depending on whether we are talking about immigration or emigration.

\frac{d P}{d t}=r_g \pm r

This is further explained below.

<h3>What is a differential equation?</h3>

Generally, The rates of births and deaths will be represented accordingly by the superscripts r_b and r_d.

The model transforms into the following when subjected to the circumstances outlined in the problem:

\frac{d P}{d t}=r_b P-r_d P^2

In conclusion, You need to submit model 1 in order to get more information.

In the event that the proportionality assumptions about birth and death be loosened up, the model that is necessary for issue 1 would become the following:

\frac{d P}{d t}=r_g \pm r

Depending on whether we are discussing immigration or emigration, we may be contemplating either of these options.
