The table represents an exponential function.

Mathematics
1 answer:
Mama L [17]3 years ago
3 0

Answer:

Step-by-step explanation:

All we are doing here is solving for the b in

y=a(b)^x, which is the standard form for an exponential function.

Use the first 2 coordinate pairs to solve for b: (1, 6) and (2, 4):

6=a(b)^1 so

a=\frac{6}{b} and use that when you write the next equation using the next coordinate pair:

4=\frac{6}{b}(b)^2 which simplifies to

4 = 6b so

b=\frac{2}{3}, the second choice there. Another way of saying multiplicative rate is the rate of decay or the rate of growth. Same thing. This is decay since 2/3 is greater than 0 but less than 1.

If l is a line whose equation is y=5x-3, find the equation of the image of l under each of the following translations a. (x,y) -
Naddika [18.5K]
Consider the line y=5x-3. Two solutions (x, y) of this equation, are points on the line.

For example, let x=0, then y=-3. So (0, -3) is a point on the line.

If x=1, then y=5*1-3=5-3=2, so (1, 2) is a point on the line.

a) 

Consider the transformations of these two points under <span>(x,y) --> (x, y-6):

</span>(0,-3) --> (0, -3-6)=(0, -9),
(1, 2) --> (1, 2-6)=(1, -4).

So (0, -3) and (1, 2) are translated to respectively (0, -9) and (1, -4).

The whole line is translated to the line containing (0, -9) and (1, -4).

The slope of the new line is m= \frac{-9-(-4)}{0-1}= \frac{-5}{-1}=5. The equation of the line is:

                                   y-(-9)=5(x-0), 

that is,                               y=5x-9.


b) 

Consider the transformations of these two points under (x,y) --> (x+2, y):

(0,-3) --> (0+2, -3)=(2, -3),
(1, 2) --> (1+2, 2)=(3, 2).

The slope of the new line is m= \frac{-3-2}{2-3}= \frac{-5}{-1}=5.

The equation of the line is
                 
                                   y-2=5(x-3), 
which can be written as
                                        y=5x-13.


Answer:

a)  y=5x-9

b)  y=5x-13

A plumber charges $47.50 per hour plus a
aniked [119]

Answer:

445 dollars

Step-by-step explanation:

You are given he charges 47.5 per hour so 47.5x is how much you will pay for x hours and he charges a 65 dollar service fee.

So together he is charge you 47.5x+65 for x hours.

If it spends 8 hours, the cost will be 47.5(8)+65=445.
