Answer:
B. f(n) = 16(3/2)^(n - 1).
Step-by-step explanation:
You can just substitute values. For questions like these, I usually use the second or third value to try the equations, because most of the time, the people who made these problems would make them all work for the first or last values.
A: 8n + 8 = 8 * 3 + 8 = 24 + 8 = 32. 32 is not equal to 36, so you can eliminate A.
B: 16 (3/2)^ (n - 1) = 16 * (1.5)^ (3 - 1) = 16 * (1.5)^ 2 = 16 * 2.25 = 36. 36 = 36, so you can keep this choice... for now.
C: 3/2 (n - 1) + 16 = 1.5 * (3 - 1) + 16 = 1.5 * 2 + 16 = 3 + 16 = 19. 19 does not equal 36, so you can eliminate C.
D: 3/2 (16)^ (n - 1) = 1.5 * (16)^ (3 - 1) = 1.5 * 16^2 = 1.5 * 256 = 384. 384 does not equal 36, so you can eliminate D as well.
Since A, C, and D do not work, you can say that the explicit form of the function would be Choice B.
Just to be sure, you can check using all four values...
f(1) = 16 * (1.5)^0 = 16 * 1 = 16 TRUE
f(2) = 16 * (1.5)^1 = 16 * 1.5 = 24 TRUE
f(3) = 16 * (1.5)^2 = 16 * 2.25 = 36 TRUE
f(4) = 16 * (1.5)^3 = 16 * 3.375 = 54 TRUE
Since all of the values match up, you can be sure that Choice B is the right answer.
Hope this helps! :)
The explicit form of the function that describes the sequence is
[tex]T_n[/tex] = 16 (1.5[tex])^{n-1[/tex].
What is Explicit form?Without expressing the other terms of the sequence, explicit formulas are always utilised to represent any term of the sequence. The word "explicit" means something that may be found directly without having to know the other phrases in the sequence. A single formula, known as the explicit formula, can be used to describe each term in a series in an individual way.
we have sequence
16, 24, 36, 54, ......
So, a = 16
r =24/16 = 1.5
So, the standard form of explicit form
[tex]T_n = a r^{n-1[/tex]
Then, [tex]T_n[/tex] = 16 (1.5[tex])^{n-1[/tex]

1000 mL = 1 L
a)
2800 cm³ × (1 mL)/(1 cm³) × (1 L)/(1000 mL) = 2.8 L
b)

Answer:
The 3rd one
Step-by-step explanation:
You have already collected $20. You need at least $160, but having even more money would be great. You need $160, but any number to the right of 160 would be even better as your goal.
a number cube numbered 1-6 is rolled 30 times and lands on an even number 18 times. How does this frequency compare to the expected frequency based on the probability of the number cube landing on an even number?
Answer:
The frequency is 3 more than expected
Step-by-step explanation:
There are 3 favourable outcomes: {2, 4, 6}
There are 6 possible outcomes: {1, 2, 3, 4, 5, 6}
probability of the number cube landing on an even number = favourable outcomes / possible outcomes = 3/6 = 1/2
If the cube is rolled 30 times, it is expected that in 1/2*30 = 15 times landed on an even number. The frequency: 18 is 3 more than expected

Lindsey lives 32 blocks from the grocery store. It takes her 9 minutes to walk 12 blocks. If she continues to walk at the same rate, how long would it take her to walk 32 blocks?
Answer:
if she countinues to walk at that rate it will take her 24 minutes to walk the 32 blocks
Step-by-step explanation:
i took the 12 blocks every 9 minutes and counted for a total of 36 blocks which would take 27 minutes then since we want to know how long it would take for her to walk 32 blocks I found how long it would take her to walk 4 blocks which is 3 minutes (12/3 = 4 9/3 =3) and i subtracted those 3 minutes from the 36 block walk giving you 24 minutes for 32 blocks

-8
-3.7
1/3

12
Answer:
12, -3.7, ⅓
(2nd, 3rd and 5th option)
Step-by-step explanation:
Constants are numbers without any variables with it.
x and y are the variables here.
-8 is the coefficient of y and hence it is not a constant.
*the value of a constant will not change
Note that the constant includes the symbol too, hence it is -3.7 and not 3.7.

Hey there! :)
Answer:
f(x + 5/4) --> f(x) is translated 5/4 units left.
f(x) - 5/4 --> f(x) is translated 5/4 units down.
Step-by-step explanation:
Recall that a linear equation in transformations form is:
f(x) = ±a(b(x-h))+k
In this instance:
f(x + 5/4) the 'h' value is -5/4, meaning the graph is translated 5/4 units left.
f(x) - 5/4 has a 'k' value of -5/4, so the graph is translated 5/4 units down.

Find the equation of the exponential function represented by the table below:
HELLPPP
Answer:
y = 4 [tex](\frac{1}{2}) ^{x}[/tex]
Step-by-step explanation:
For an exponential function in the form
y = a [tex]b^{x}[/tex]
Use ordered pairs from the table to find values of a and b
Using (0, 4 ), then
4 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), thus
a = 4, so
y = 4 [tex]b^{x}[/tex]
Using (1, 2 ) , then
2 = 4 [tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
b = [tex]\frac{1}{2}[/tex]
Thus exponential function is
y = 4 [tex](\frac{1}{2}) ^{x}[/tex]
Answer:
y = 4 (\frac{1}{2}) ^{x}
A rectangular prism has a length of 9 in., a width of 4 in., and a height of 1 1/2in. The prism is filled with cubes that have edge lengths of 1/2 in. How many cubes are needed to fill the rectangular prism?
Hey there! :)
Answer:
432 cubes.
Step-by-step explanation:
Volume of rectangular prism: V = l × w × h
V = 9 × 4 × 1.5
V = 54 in³
Volume of cubes: V = s³
V = 1/2³
V = 1/8 in³
Set up an equation to solve for the # of cubes needed (x):
54 = 1/8x
Divide both sides by 1/8:
54 × 8/1 = x
x = 432 cubes.
this is a sketch of the curve with equation y=f(x) the vertex of the curve is at (2,-3)
Answer:
see explanation
Step-by-step explanation:
(a)
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
f(x) + 5 represents a shift up of 5 units, thus
(2, - 3 ) → (2, - 3 + 5 ) → (2, 2 )
(b)
Given f(x) then - f(x) represents a reflection of f(x) in the x- axis
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(2, - 3 ) → (2, 3 )
The vertex of the given curve is the minimum point on the curve.
The vertex of f(x) + 5 is (2,2)The vertex of -f(x) is (2,3)The vertex is given as:
[tex]\mathbf{(x,y) = (2,-3)}[/tex]
(a) The vertex of f(x) + 5
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,y + 5)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-3 + 5)}[/tex]
[tex]\mathbf{(x,y) \to (2,2)}[/tex]
Hence, the vertex of f(x) + 5 is (2,2)
(b) The vertex of -f(x)
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-(-3))}[/tex]
[tex]\mathbf{(x,y) \to (2,3)}[/tex]
Hence, the vertex of -f(x) is (2,3)
