Write an exponential function in the form y = a that goes through points ( 0 , 13 ) and ( 2 , 637 )
kiruha [24]

Answer:

$ y = (13)7^x $

Step-by-step explanation:

When two points are given say, $ (x_1, y_1) $ and $ (x_2, y_2) $ the exponential function passing through these points is given by

                                               $ y = ab^x $

This is obtained by solving for $ a $ and $ b $ in

$ y_1 = ab^{x_1} \hspace{15mm} (1) $

$ y_2  = ab^{x_2} \hspace{15mm} (2) $

when we solve (1) and (2) for $ a $ and $ b $ we substitute it in the main equation to get the desired exponential function.

Here: $ (x_1, y_1) = (0, 13) $ and $ (x_2, y_2) = (2, 637) $.

Substituting in (1) and (2), we get:

$ 13 = ab^0 $

$ 637 = ab^2 $

From the first equation we get: $ a = 13 $  [since $ b^0 = 1 $].

Now substitute a = 13 in the second equation to get the value of b.

$ \implies 637 = (13)b^2$

$ \implies b^2 = 49 $  $ \implies b = 7 $

Substituting the values in the main equation we get:

  $  y = (13)7^x $

I need step by step help how to work this out​
DerKrebs [107]

Answer:

31.73

Step-by-step explanation:

3x^{2} +5y

x = 2.1

y = 3.7

Substitute;

3(2.1)^{2} +5(3.7)=3(4.41)+18.5=13.23+18.5=31.73

NEED HELP ALGEBRA 1
tigry1 [53]
<h3>Answer: E) 1/5</h3>

========================================================

Method 1

Use your calculator to find the decimal version of each fraction

  • 4/10 = 0.40
  • 12/25 = 0.48
  • 14/20 = 0.70
  • 28/50 = 0.56
  • 1/5 = 0.20

We see that 0.20 is the smallest decimal of the list, so 1/5 is the smallest fraction of the list.

----------------------------

Method 2

To compare fractions, we need to get all of the denominators to the same value. A good target is the lowest common denominator (LCD)

In this case, the LCD is 100

  • 4/10 = 40/100 .... multiply top and bottom by 10
  • 12/25 = 48/100 .... multiply top and bottom by 4
  • 14/20 = 70/100 .... multiply top and bottom by 5
  • 28/50 = 56/100  .... multiply top and bottom by 2
  • 1/5 = 20/100  .... multiply top and bottom by 20

The last fraction has the smallest denominator, so 1/5 is the smallest.
