Find the 6th term of the geometric sequence whose common ratio is 3/2 and whose first term is 6.
Answer:
The 6th term will be:
[tex]a_6=\frac{729}{16}[/tex]
Step-by-step explanation:
Given
a₁ = 6common ratio r = 3/2To determine
a₆ = ?
A geometric sequence has a constant ratio r and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
substituting a₁ = 6, r = 3/2
[tex]a_n=6\cdot \left(\frac{3}{2}\right)^{n-1}[/tex]
Determining 6th term
substituting n = 6 in the given equation
[tex]a_n=6\cdot \left(\frac{3}{2}\right)^{n-1}[/tex]
[tex]a_6=6\cdot \left(\frac{3}{2}\right)^{6-1}[/tex]
[tex]=6\cdot \frac{3^5}{2^5}[/tex]
[tex]=\frac{3^5\cdot \:6}{2^5}[/tex]
[tex]=\frac{3^5\cdot \:2\cdot \:3}{2^5}[/tex]
Cancel the common term
[tex]=\frac{3^6}{2^4}[/tex]
[tex]=\frac{729}{16}[/tex]
Therefore, the 6th term will be:
[tex]a_6=\frac{729}{16}[/tex]
x + 3y = 18
-X - 4y = -25
Answer:
x = -3
y= 7
Step-by-step explanation:
x + 3y=18 ----(1)
-x - 4y=-25 -----(2)
from equation (1)
x = 18 - 3y ---(3)
putting equation (3) into equation (2)
-(18 - 3y) - 4y = -25
18 + 3y -4y = -25
3y - 4y = -25 - 18
-y = -7
y = 7 ✓
Putting y=7 into equation (1)
x + 3(7) = 18
x + 21 = 18
x = 18 - 21
x = -3 ✓
Liam wants to buy a Nintendo Switch. The Switch costs $350 plus tax. He has $380. If tax is 9%, will he have enough to buy the Switch?
Step-by-step explanation:
I'm not a 100 % sure but 350.00 x 0.06 =21 so 350 +21 = 371.00
Answer:
No
Step-by-step explanation:
Switch=$350 + tax = ???
Liam's Money= $380
350*9/100=tax
tax=$31.50
350+31.50=$381.50
that's how much he would need to pay: 381.50

Answer:
15200mm
Step-by-step explanation:
I just asked googl
Answer:
15.2m is 15200mm
Step-by-step explanation:
you multiply or divide the original number by however many tens places the other measurement is away. So, 15.2(m) is 3 tens places away from (mm) so you would multiply 15.2(m) by 1000 (15.2 x 1000) and you would get 15200

Is y=-3.5x-10 proportional
Answer: =3.5x Slope:
3.5
y-intercept:
0
Step-by-step explanation:
y=-3.5x-10 is an inverse proportional.
Given that, the given equation is y= -3.5x-10.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
Put x=0, 1, 2, 3, and 4 in the given equation.
When x=0
y=-10
When x=1
y=-3.5(1)-10
=-3.5-10
=-13.5
When x=2
y=-3.5(2)-10
=-7-10
=-17
When x=3
y=-3.5(3)-10
=-10.5-10
=-20.5
Here, x increases and y decreases, it is inverse proportionality
Therefore, y=-3.5x-10 is an inverse proportional.

A student committee is organizing a school dance as a fundraiser. The function f ( x ) = 5 x − 320 represents the total amount of funds raised based on the number of tickets sold, x , minus the cost of decorations
I assume you want this explained
Answer and explanation:
If the function f ( x ) = 5 x − 320 represents the total amount of funds raised based on the number of tickets sold, x , minus the cost of decorations then x number of tickets is an independent variable here that will determine the total amount of funds raised y(dependent variable)
The y intercept is -320 and the slope is 5
If for example the number of tickets sold = 100 tickets
Total amount of funds using the function :
f(100)= 5×100-320
=500-320
= $180
Answer:
The slope of the function is 5, and it represents the price of each ticket .

Colin gets £x wages each week. After he pays his tax of £t, he
then pays his rent of £120. He shares what's left between
himself and his wife. How much do they each get?
Answer:
They will each get ;
(x-t)/2 - 60
Step-by-step explanation:
Here, we want to know the amount of money that Colin and his wife gets
we start by subtracting the necessary terms
Mathematically, that would be;
x-t-120
So what each of them get will be;
(x-t-120)/2
= (x-t)/2 - 60

Geraldine is asked to explain the limits on the range of an exponential equation using the function f(x) = 2x. She makes these two statements:
1. As x increases infinitely, the y-values are continually doubled for each single increase in x.
2. As x decreases infinitely, the y-values are continually halved for each single decrease in x.
She concludes that there are no limits within the set of real numbers on the range of this exponential function. Which best explains the accuracy of Geraldine’s statements and her conclusion?
Statement 1 is incorrect because the y-values are increased by 2, not doubled.
Statement 2 is incorrect because the y-values are doubled, not halved.
The conclusion is incorrect because the range is limited to the set of integers.
The conclusion is incorrect because the range is limited to the set of positive real numbers.
Answer:
The conclusion is incorrect because the range is limited to the set of positive real numbers.
Step-by-step explanation:
The conclusion is incorrect because the range of the function f(x) = 2x includes all positive real numbers.
What is a function?A relation is a function if it has only One y-value for each x-value.
Statement 1 is actually correct, because as x increases by 1, the value of f(x) = 2x is multiplied by 2.
Therefore, the y-values are indeed doubled for each single increase in x.
Statement 2, however, is incorrect, because as x decreases by 1, the value of f(x) is divided by 2, not halved.
Therefore, the accuracy of Geraldine's statements is mixed.
The range of the function f(x) = 2x includes all positive real numbers, not just integers or positive integers.
Therefore, the conclusion is incorrect because the range of the function f(x) = 2x includes all positive real numbers.
