The equation says that it rained 4.12 inches on Monday and 1.01 less on Tuesday.

So to write in number form = 4.12 - 1.01 = 3.11

So your answer is 3.11 inches.

It rained 3.11 inches on Tuesday.

Hope this helps!

Ned is driving at 72km/h, at this rate how long (in hours and minutes) will it take him to drive 210km

beks73 [17]

Answer:

2 hours 55 minutes

Step-by-step explanation:

calculate time (T) using the relationship

T = $\frac{D}{S}$ ( D is distance , S is average speed )

T = $\frac{210}{72}$ = 2.9166... hours

to convert to hours and minutes multiply the decimal part by 60 , that is

0.9166.. × 60 = 55 minutes

then time taken to drive 210 Km is 2 hours 55 minutes

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.
