Answer:

The second choice has the largest rate of change by 3

Step-by-step explanation:

you find the slopes of all of them.

# 1 has a slope of 2

# 2.   \frac{y^{2}-y^{1} }{x^{2}-x^{1}  }  = \frac{12 - 6}{3 - 1} = \frac{6}{2} = 3

# 3. has a slope of -5

# 4. \frac{y^{2}-y^{1} }{x^{2}-x^{1}  } = \frac{2.5 - 3}{1 - 0} = \frac{-0.5}{1}= -0.5

\boxed{\sf \ \ \ answer \ b. \ \ +5 \ \ \ }

Step-by-step explanation:

Hello

let's assume that we are looking for x >=0

4x^2=100  \dfrac{4x^2}{4}=x^2=\dfrac{100}{4}=25\\\sqrt{x^2}=25\\ |x| = 5  x = 5 \ or \ x=-5

Let's assume that we are looking for x>=0

so the correct answer is 5

You could interpret them as system of equation and answer the question easily

from A 

-4x + y + x + w =1

write in same form from A 

as this system has five variables and four of them are unknowns it means the unique solution is not possible 

So, det (A) = 0

A 20 foot extension ladder is placed in a wall making an angle of elevation for 85 degrees with the ground. If a person at the t
snow_tiger [21]

Answer:

21.74 ft

Step-by-step explanation:

We use Cosine because we are dealing with the Adj and Hyp

Cos 85 = x/20

x = 20 Cos 85

x = 1.74 feet away from the base of the wall.

Since the ladder is 20 foot long, the total distance will be 1.74 + 20 = 21.74 ft

Ariane borrows $200 on a 5 year loan she is charged 5% simple interest how much interest is she charged for 5 years what is the
ycow [4]

Answer:

Interest: $50 | Total: $250

Step-by-step explanation:

You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.

I = Prt

<em>I = interest amount </em>

<em>P = principal amount </em>

<em>r = interest rate (decimal form) </em>

<em>t = time</em>

<em />

Now we can plug in the values into the equation:

I = 200(.05)(5)

I = 50

This means that Ariane is charged $50 worth of interest. She has to pay back $250 total dollars.
