Answer:
C (-354, 294)
Step-by-step explanation:
The geometric explicit formula is gn= g1 · [tex]r^{n-1}[/tex].
N represents the term you are looking for which, in this case, is the 12th term. R represents the common ratio which, in this case, is +3.
G1 represents the first term in the sequence which, in this case, is -2.
Now you solve using this equation: g12 = -2 · [tex]3^{12-1}[/tex].
12 minus 1 is 11. [tex]3^{11}[/tex] is 177147. 177147 times -2 is -354294.
And that is your final answer; -354,294

(2, 6)
(4, 12)
(6, 18)
Step-by-step explanation:
Time represents s, or the x value when plotting (x, y) and distance represent m or the y value when plotting.
For the first one, plot it at (1, 3), so look where time is, the horizontal line, and find one. Then from there, go up three places. That is where you will plot your first point.
The second one will be plotted at (2, 6). Find two on the horizontal line, and then go up six spaces. That is where you will plot your second.
Do the same thing for the last two. You should plot your points at:
(1, 3)
(2, 6)

Answer:
(b) (6, 0)
Step-by-step explanation:
You are given the value of x. Substitute that in the other equation and find the value of y.
-3x +14y = -18
We know x=6 from the second given equation, so ...
-3(6) +14y = -18
Add 18 to both sides
14y = 0
Divide by 14
y = 0
Then the solution is ...
(x, y) = (6, 0)

Answer:
[tex](-2-2\sqrt{2},3+2\sqrt{2})\,,\,(-2+2\sqrt{2},3-2\sqrt{2})[/tex]
Step-by-step explanation:
Given:
[tex](x+2)^2+(y-3)^2=16\\x+y-1=0[/tex]
To find: value of [tex]x,y[/tex]
Solution:
[tex](x+2)^2+(y-3)^2=16\,\,\,...(i)\\x+y-1=0\,\,\,(ii)[/tex]
From (ii),
[tex]x=1-y[/tex]
Put this value of [tex]x[/tex] in (i)
[tex](1-y+2)^2+(y-3)^2=16\\(3-y)^2+(y-3)^2=16\\(y-3)^2+(y-3)^2=16\\2(y-3)^2=16\\(y-3)^2=8[/tex]
[tex]y-3=[/tex] ± [tex]\sqrt{8}[/tex] = ± [tex]2\sqrt{2}[/tex]

Riley has a loyalty card good for a 12% discount at her local pharmacy. What would
her total in dollars and cents be, after the discount and before tax, if the total cost of
all the items she wants to buy is $17.50? Round to the nearest cent.
Answers
Answer:
The cost after discount would be $15.40
Step-by-step explanation:
Given that:
Discount card = 12%
Cost of items bought = $17.50
Amount of discount = 12% of 17.50
Amount of discount = [tex]\frac{12}{100}*17.50[/tex]
Amount of discount = 0.12 * 17.50
Amount of discount = $2.10
Cost after discount = 17.50 - 2.10
Cost after discount = $15.40
Hence,
The cost after discount would be $15.40

Answers
Answer:
25 chairs
Step-by-step explanation:
If 40 chairs are bought for Rs 10000 then how many chairs must be sold for Rs 10000 so as to gain 60%?
The percent gain = 60%
Number of chairs to be sold = x
Hence:
40 chairs = 10,000
60/100= 40 - x/x × 100
0.6= 40 - x/x
Cross Multiply
0.6x = 40 - x
0.6x + x = 40
1.6x = 40
x = 40/1.6
x = 25 chairs

A company dyes two sizes of rugs. A small rug requires 4 hours for dyeing, and a medium-size rug requires 6 hours for dyeing. The dyers have to make at least 20 rugs, and they must do it in less than 120 hours. Let x equal small rugs and y equal medium rugs. Which of the following inequalities can be paired with x + y ≥ 20 to create a system that represents this situation?
Answers
Answer:
Answer:
Option (b) is correct.
4x + 6y < 120 inequalities that can be paired with x + y ≥ 20 to create a system that represents the given situation.
Step-by-step explanation:
Given: A small rug requires 4 hours for dyeing and a medium-size rug requires 6 hours for dyeing. The dyers have to make at least 20 rugs, and they must do it in less than 120 hours.
We have write an inequalities that can be paired with x + y ≥ 20 to create a system that represents the given situation and choose the correct option from given options.
Let x represents the small rugs and y represents the medium rugs.
Also, x + y ≥ 20 represents the dyers have to make at least 20 rugs.
And it is given that a small rug requires 4 hours for dyeing and a medium-size rug requires 6 hours for dyeing and that they must do it in less than 120 hours.
So, time taken to dye x small rugs = 4x
also, time taken to dye y medium rugs = 6y
And they have maximum of 120 hours.
So this inequality is represented by 4x + 6y < 120
The answer is: 4x + 6y < 120
