What is the quotient?

Aleksandr [31]

Answer:

(A) $4X10^{12}$

Step-by-step explanation:

Given the quotient:

$\dfrac{6*10^8}{1.5*10^{-4}}$

To evaluate, we first separate the given expression as follows.

$=\dfrac{6}{1.5}X\dfrac{10^8}{10^{-4}}$

Next, we apply the division law of indices to the powers of 10.

Division Law of Indices: $\frac{a^x}{a^y}=a^{x-y}$

$=4X10^{8-(-4)}\\=4X10^{8+4}\\=4X10^{12}$

Therefore, our quotient is $4X10^{12}$ .

The correct answer is A.

Which set of ordered pairs could be generated by an exponential function?A.(0,0),(1,1),(2,8),(3,27)B.(0,1),(1,2),(2,5),(3,10)C.(

Travka [436]

Answer:

Option D

Step-by-step explanation:

Let an exponential function

$f(x)=ab^x$

Where a=Constant $\neq 0$

$b\neq 0$

We know that

$b^0=1$

Therefore,

Point (0,0) can not be obtained by exponential function.

Hence,option A and C are incorrect.

Substitute (0,1)

$1=a$

$f(x)=b^x$

Substitute (1,2)

$2=b^1$

$\implies b^2=4\neq 5$

Hence, option B is incorrect.

D.(0,1),(1,3),(2,9),(3,27)

$f(1)=b=3$

$b^2=(3)^2=9$

$b^3=3^3=27$

Hence, option D is correct.

kicyunya [14]

Answer: 5 cookies and 6 brownies.

Step-by-step explanation: If she decides to buy 5 cookies it will cost her $2.50. This means she can still spend $12.50. If we need to find how many brownies she can buy, the expression 12.50/2.25 can explain. In this case, she can buy 5 brownies and will have $1.25 left over
