7) is not an arithmetic sequence...
9) [tex]0.5 \cdot 4^x[/tex]
10) [tex]-0.25 \cdot (-8)^x[/tex]
Step-by-step explanation:
7 is not an arithmetic sequence because consecutive terms of the sequence do not have a constant common difference.
9 has a first term of 0.5 and has a common ratio of 4 (the quotient between the second term and first, then third term and second, etc.). Thus, your equation is [tex]0.5 \cdot 4^x[/tex]
10 has a first term of -0.25 and has a common ratio of -8 (the quotient between the second term and first, then third term and second, etc.). Thus, your equation is [tex]-0.25 \cdot (-8)^x[/tex]

Answer:
44°
Step-by-step explanation:
From sin rule:
a / sin A = b / sin B = c / Sin C
3.6 / sin b = 5.1 / sin 100
Cross multiply :
5.1 * sinb = 3.6 * sin 100
Sin b = 3.5453079 / 5.1
Sin b = 0.6951584
b = sin^-1(0.6951584)
b = 44.039
b = 44°

The amount of money spent at Cherry Hill Mall continues to increase. The total in millions of dollars, can be estimated f(x) = 12(1.12)^{x}, where x is the number of years after the expansion in 2005. According to this model, how much money is being spent this year?
Answers
Answer:
$73,564,723.80
Step-by-step explanation:
"x is the number of years after the expansion in 2005"
This year is 2021.
2021 - 2005 = 16
x = 16
[tex] f(x) = 12(1.12)^{x} [/tex]
[tex] f(16) = 12(1.12)^{16} [/tex]
[tex] f(16) = 73.56 [/tex]

Suppose that 70% of all Americans agree that a candidate is not trustworthy. A survey finds the 116 out of 200 agree that a candidate is not trustworthy. How likely is the result above to happen, if the sample is representative of the population?
Answers
Answer:
Prob = 0.00009 = 0.009% , Less Likely
Step-by-step explanation:
Using Binomial Distribution, Prob = N c r . ( P )^ r . ( Q ) ^ (n -r) .
,P = success probability, ie candidate considered be trustworthy = 70% = 0.7; N = trials = 200 ; Q = failure probability, ie non trustworthy = 1 - 0.7 = 0.3 r = no. of success = 116
Pr = 200c116 . (0.7)^116 . (0.3)^(200 - 116) = 200c116 (0.7)^116 (0.3)^84 = 0.00009 = 0.009%
Less probability means Less Likely
Use the explicit rule given to write the first four terms the sequence
F(n)=n²+7
Answers
Answer:
8, 11, 16, 23
Step-by-step explanation:
the rule is: f(n) = n²+7
first 4 terms are:
f(1) = 1² +7 so f(1) = 8
f(2) =2² +7 so f(2) = 11
f(3) = 3² +7 so f(3) = 16
f(4) = 4² +7 so f(4) = 23

Step-by-step explanation:
Area of triangle = bh/2 = 4(8)/2 = 16
Area of both triangles = 32
Area of left face = bh = 8(12) = 96
Area of right face = bh = 9(12) = 108
Area of bottom = bh = 4(12) = 48
Total lateral area = 32 + 96 + 108 + 48 = 284

Given g(x)=Squareroot x-4 and h(x)=2x-8, what is g(h(10))
Answers
Answer:
[tex]g(h(10)) = 2\sqrt 2[/tex]
Step-by-step explanation:
Given
[tex]g(x) = \sqrt {x - 4[/tex]
[tex]h(x) = 2x - 8[/tex]
Required
[tex]g(h(10))[/tex]
First, calculate [tex]g(h(x))[/tex]
We have:
[tex]g(x) = \sqrt {x - 4[/tex]
This gives:
[tex]g(h(x)) = \sqrt {h(x) - 4[/tex]
Substitute [tex]h(x) = 2x - 8[/tex]
[tex]g(h(x)) = \sqrt {2x - 8 - 4[/tex]
[tex]g(h(x)) = \sqrt {2x - 12[/tex]
Substitute [tex]x = 10[/tex]
[tex]g(h(10)) = \sqrt {2*10 - 12[/tex]
[tex]g(h(10)) = \sqrt {20 - 12[/tex]
[tex]g(h(10)) = \sqrt {8\\[/tex]
Split
[tex]g(h(10)) = \sqrt {4} * \sqrt 2[/tex]
This gives
[tex]g(h(10)) = 2\sqrt 2[/tex]

Step-by-step explanation:
A cube has a volume of 729 cubic centimeters. What can be concluded about the cube? Check all that apply.
Recall the formula Cube volume = s cubed.
The side length, s, can be found using the equation 3 s = 729
This is a perfect cube.
The side length is 243 centimeters.
The side length is 9 centimeters.
Taking the cube root of the volume will determine the side length.
If you multiply the volume by three, you can determine the side length.

Step-by-step explanation:
i took the test
The true conclusion about the cube are :
This is a perfect cube
The side length is 9 centimeters
Taking the cube root of the volume will determine the side length.
What is volume?A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere. Different shapes have different volumes.
Volume of a cube = l³
where
l = length
Therefore,
volume = l³
729 = l³
cube root both sides
l = ∛729
l = 9 cm
Therefore, what is true about the cube is as follows:
This is a perfect cube
The side length is 9 centimeters
Taking the cube root of the volume will determine the side length.
