Exponential Function:
vovangra [49]

Answer:

See below

Step-by-step explanation:

<em>On the graphs we see transformations of exponential functions</em>

<h3>Graphic 1 = Horizontal shift </h3>
  • f(x) = 2ˣ is the parent function
  • g(x) = 2ˣ⁺³ indicates shift to the left by 3 units
  • h(x) = 2ˣ⁻¹ indicates the shift to the right by 1 unit
<h3>Graphic 2 =Vertical shift</h3>
  • p(x) = (1/3)ˣ is the parent function
  • r(x) = (1/3)ˣ⁺³ indicates shift up by 3 units
  • q(x) = (1/3)ˣ⁻² indicates the shift down by 2 units

What is an equation of the line that is perpendicular to y-3 =-4(x+2)​
serg [7]

Answer:

y - 3 = \frac{1}{4}(x+2) or choose any line with slope 1/4

Step-by-step explanation:

The slope of this line is -4. The slope of the line perpendicular to this line will be the negative reciprocal or 1/4.

Write the equation using the slope m=1/4 and the point slope form.

y-y_1=m(x-x_1)\\y-3=\frac{1}{4}(x+2)

This is the equation of the line that is perpendicular and passes through the same point (-2,3) as the equation listed.

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.

chris invests $14,000 at 4% simple interest for 2 year. How much is in the account at the end of the 2 years period?
Charra [1.4K]
<em>Hi there,</em>

Principle Amount = $14000

Interest for 1 year = 4% x 14000 = 0.04 x 14000 = $560
Interest for 2 years = 560 x 2 = $1120

Total amount at the end of the period = $14000 + $1120 = $15120

Answer: $15120

<em>Hope it helps,</em>
