Step-by-step explanation:

normally there are 6 surface areas on a prism (or simply "box").

for the lateral surface area we ignore the indicated (shaded) areas as to and bottom. that leaves us with the 4 white ones.

so, we have 2 rectangles of 4×3 and 2 rectangles (the missing side lengths must be identical to the other specified lengths given the graphic, otherwise the sides would not fit together to build the prism) of 1.5×4.

the total lateral surface area is therefore

2×3×4 + 2×1.5×4 = 24 + 12 = 36 ft²

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.

Christian sold tickets to the game . Good seats were $5 each and poor seats cost $2 each. 210 people attended and paid $660. How

Sholpan [36]

People who purchased good seats will be labeled as a
people who purchased poor seats will be labeled as b
therefore...
5a + 2b = 660
a + b = 210
Now, all that has to be done is for the system to be solved.
-2(a+b=210)

5a + 2b = 660
-2a - 2a = -420

3a=240
a= 80
*3 people purchased good seats.

Now we can plug that number in

5(80) + 2b = 660
400 + 2b = 660
2b = 260
b = 130
*130 people purchased poor seats
