Describe and correct the error a student made in writing an exponential function

NemiM [27]

Answer:

we CANNOT DIVIDE 3 with 6.

Step-by-step explanation:

Here,as given in the question:

Starting value = 6

Constant ratio = 1/3

Now, exponential function is obtained by the product of starting value and the constant ratio repeatedly.

⇒ f(x) = (Starting value) x (ratio)... x times

$\implies f(x) = 6 (\frac{1}{3} )^x = 6 (\frac{1}{3} ) (\frac{1}{3} ) (\frac{1}{3} ) .... x$

Now, we CANNOT DIVIDE 3 with 6 as it is in the power of x.

Hence, $\implies f(x) = 6 (\frac{1}{3} )^x$ and $f(x) \neq 2^x$

Describe and explain the possible values of s, the number of student tickets sold, and e, the number of tickets sold to nonstude

Marat540 [252]

Answer:

(20,0) , (0,16) , (5,12) , (10,8) , (15,4)

Step-by-step explanation:

Total amount of tickets sold = 80

Per ticket price for students = 4 ; Per ticket price for non students = 5

Let no. of students be s , no. of non students be x

Equation : 4s + 5x = 80

So, Maximum number of student tickets sold (assuming all student, no 'non student' tickets) = 80 / 4 = 20

Maximum number of non student tickets sold (assuming all 'non student', no 'student' tickets) = 80 / 5 = 16

Other possible values {s,x} , as per equation = (5,12) , (10,8) , (15,4)

Accomplished silver workers in india can pound silver into incredibly thin sheets, as thin as 3.00 10-7 m (about one-hundredth o

Vlad1618 [11]

The density of silver is 10,500 kg/m^3, therefore the volume of a 2.90 kg silver is:

V = 2.90 kg / (10,500 kg/m^3)

V = 0.000276 m^3

We know that volume is simply area times height:

Volume = Area * height

SO the area is:

Area = 0.000276 m^3 / 3.00 x 10-7 m
