Find an explicit rule for the nth term of the sequence.
-2, -8, -32, -128
Answer:
[tex]a_{n}[/tex] = - 2 [tex](4)^{n-1}[/tex]
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
r = - 8 ÷ - 2 = - 32 ÷ - 8 = - 128 ÷ - 32 = 4
This indicates the sequence is geometric with nth term
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 2 and r = 4 , then explicit formula is
[tex]a_{n}[/tex] = - 2 [tex](4)^{n-1}[/tex]

12) Two hexagonal pyramids are similar. The perimeters of the pyramids are 36 inches and 30
inches. If the volume of the larger pyramid is 64873 in what is the volume of the smaller
pyramid?
Please help me:)
Answer:
54061 in³
Step-by-step explanation:
Using proportion
Perimeter of smaller pyramid/ Perimeter of Larger pyramid = volume of smaller pyramid/ volume of Larger pyramid
30/36 = x/64873
Cross Mulitiply
36 × x = 64873 × 30
x = 64873 × 30/36
x = 54060.833333 in³
Approximately = 54061 in³
Therefore, the volume of the smaller pyramid is 54061 in³

which graph represents a function?
Answer: The 2nd graph
Step-by-step explanation:
Using the vertical line test, all other 3 graphs have two points that meet on the same lines. This immediately rules all other 3 graphs out as a graph cannot have two points with the same x-axis.
3. What should be done to the following equation to get the variable on the left side only?
-3x + 6 = x - 4
a. Add 3x to both sides.
b. Add x to both sides.
C. Subtract 3x from both sides.
d. Subtract x from both sides.
e. Either a or b.
. Either cord.
Answer:
d. Subtract x from both sides.

-4(7.5x-8)=-5(6.3x+8)
Answer:
x = -48
Step-by-step explanation:
-4(7.5x - 8) = -5(6.3x + 8)
-30x + 32 = -31.5x - 40
-30x + 31.5x = -40 - 32
1.5x = -72
x = -72/(1.5)
x = -48
5. Evaluate the following expression when a = -4
and b = 1/2.
b|3a – 81 – 3/2 – 2a
a) -40
c) 20
b) -20
d) -10
Answer:
Step-by-step explanation:
Given the expression
b|3a – 81 – 3/2 – 2a
If a = -4, b = 1/2
Substitute
(1/2)/3(-4) - 81 - 3/2 - 2(-4)
1/2 * 1/-12 - 81 - 3/2 + 8
= -1/24 - 81 + 8 - 3/2
= -1/24 - 3/2 - 73
= -1-36-1,752/24
= -1,789/24
= -74.5

calculate the area of the kitchen if the outer wall with the window is 10 feet, the depth (height) of the kitchen is 7 feet, and the dotted line that connects to two walls is 8 feet.
Answer:
80 Ft²
Step-by-step explanation:
Area= length x width
length= 10 feet
width= 8 feet
A= 10 × 8
A= 80 Ft²
squared because it's feet multiplied by feet
Ft × Ft= Ft²

Diedra rolls an unbalanced die 72 times and gets a "6" 21 times. If she rolls the die 15 more times, which of these is the most reasonable prediction of the number of times she will not roll a "6"?
By using the relative frequency, we can expect to not roll a "6" in 11 rolls.
How many times can we expect to not roll a "6"?
We know that in a total of 72 rolls, the outcome is "6" 21 times.
Then the relative frequency is:
F = 21/72 = 0.292
Then we can expect that in N rolls, we will get (0.292)*N times a "6".
So the number of times that we will not get a 6, is:
(1 - 0.292)*N
In this case is N = 15, then we get:
(1 - 0.292)*15 = 10.62
Rounding to the next whole number we get 11, this means that we can expect to not roll a "6" in 11 rolls.

Answer:
y_2 is 8 units
Step-by-step explanation:
Given that
The distance between the point is 13 units
x_1 is 5
y_1 is 3
x_2 is -7
We need to find out the y_2
So, the following formula should be used
[tex]d = \sqrt({x_2 - x_1})^2 + (y_2 - y_1)^2\\\\13 = \sqrt({-7-5})^2 + (y_2 - 3)^2\\\\169 = 144 + (y_2)^2 + (-3)^2 - 2(y_2) (-3)\\\\25 = (y_2)^2 + 9 - 6y_2\\\\16 = (y_2)^2 -6y_2\\\\(y_2)^2 -6y_2 - 16 = 0\\\\(y_2)^2 - 8y_2 + 2y_2 - 16 = 0\\\\y_2 (y_2 - 8) + 2(y_2 - 8) = 0\\\\y_2 = 8[/tex]
hence, y_2 is 8 units

whats the correct equation to solve for x
Answer:
12x - 29 + 4x + 1 = 180
Step-by-step explanation:
(12x - 29) and (4x + 1) are same- side interior angles and sum to 180° , then
12x - 29 + 4x + 1 = 180 ← is the equation to solve for x
16x - 28 = 180 ( add 28 to both sides )
16x = 208 ( divide both sides by 16 )
x = 13

If a position on the ocean floor is 12 kilometers below the sea level, which value describes the elevation of the ocean floor
Answer:
- 12
Step-by-step explanation:
The sea level serves as a reference point and may be used to describe objacetsvir positions above or below it. Therefore, the sea level is regarded as a zero point or level. Hence, objects below are describes to be at a negative distance while those above are assigned the positive sign. Hence, for a position which is 12 km below sea level, then the object is said to be at a distance of - 12 km (below sea level takes the negative sign.)
