The graph of an exponential function passes through the point (0,15) and (1,10). What is the equation of the exponential functio

Vilka [71]

Answer:

$y=15(\frac{2}{3})^x$

Step-by-step explanation:

we know that

The equation of a exponential function is of the form

$y=a(b^x)$

where

a is the initial value or y-intercept

b is the base of the exponential function

In this problem we have

$a=15$ ----> the y-intercept is given

substitute

$y=15(b^x)$

we have the other ordered pair (1,10)

substitute the value of x and the value of y and solve for b

$10=15(b^1)\\10=15b$

$b=\frac{10}{15}=\frac{2}{3}$

substitute

$y=15(\frac{2}{3})^x$

see the attached figure to better understand the problem

What are the units for the variable in the following scenario?

krek1111 [17]

Answer:

Her grocery bill was $4.62.

Step-by-step explanation:

There is some mistake in question so the correct question is:

Sherry bought 6 apples at 43¢ per apple. She then bought 4 oranges at 51¢ per orange. How much was her grocery bill?

Now, to find the grocery bill.

As the units are given:

43¢ per apple and

51¢ per orange.

$1 = 100¢.

So, the cost of 6 apples = $0.43\times 6=2.58$

Thus, the cost of 6 apples = $2.58

And the cost of 4 oranges = $0.51\times 4=2.04$

Thus the cost of 4 oranges = $2.04

Now, to get the total grocery bill we add the cost of apples and oranges:

$\$2.58+\$2.04$

$=\$4.62$

Therefore, her grocery bill was $4.62.

The electrician arrives at Laura’s house to fix her broken furnace. The electrician charges 90 dollars for the first hour and 60

PIT_PIT [208]

Answer:

4 hours

Step-by-step explanation:

Since the initial fee is $90, you will subtract $90 from $330, getting $240. Since every hour after 1 hour is $60, you would divide $240 by $60 getting 4 hours
