The nth term of a sequence is 4n^2 -n-1. What is the 11th term of the sequences?
Answer:
The 11th term is 472
Step-by-step explanation:
[tex] t_{n} = 4 {n}^{2} - n - 1[/tex]
[tex] t_{11} = 4 \times {11}^{2} - 11 - 1[/tex]
[tex] = 4 \times 121 - 12 \\ = 484 - 12 \\ = 472[/tex]

What is the exact value of x?

Answer:
Step-by-step explanation:
Which equation
represents a line that passes through (2, -1/2) and has a slope of 3?
Answer:
y = 3x - 6 [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
We can use y = m x + c to find the equation of the line.
Here,
m ⇒ slope
c ⇒ y - intercept
They have already given the slope of the line.
m = 3
And now we have to find the y - intercept using the given coordinates.
( 2 , - 1/2 ) ⇒ ( x , y )
Let us find now.
y = m x + c
-1/2 = 3 × 2 + c
-0.5 = 6 + c
-0.5 - 6 = c
-6.5 = c
-6 1/2 = c
Now let us write the equation of the line.
y = m x + c
y = 3x - 6 [tex]\frac{1}{2}[/tex]

Using relations in a right triangle, it is found that the length of AC is of 6.43 inches.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.In this problem, the length of side AC is b, which is opposite to the angle of 40º, while the hypotenuse is of 10 in, hence:
[tex]\sin{40^\circ} = \frac{b}{10}[/tex]
[tex]b = 10 \times \sin{40^\circ}[/tex]
Using a calculator:
[tex]b = 6.43[/tex]

a washer and dryer cost a total of 993. the cost of the washer is two times the cost of the dryer. find the cost of each item
Let the price of the dryer = X
The washer is 2 times that so you would have 2x
Now you have X + 2x = 993
Simplify:
3x = 993
Divide both sides by 3:
x = 331
The dryer cost 331
The washer cost 2 x 331 = 662

Dario purchased a party size sub, and he decides to share it with 3 of his friends. So, he cuts the sub into 4 equal pieces. However, another one of his friends also showed up, and there are now 5 people in total.
Part A --
Now that the sub will be shared equally among 5 people, will each person get more or less sub? Briefly state why you think so.
Part B --
Dario decides to take each one of the 4 pieces and share it equally among the 5 of them.
First, he divides one piece into 5 equal parts and shares it, then the next one, and so on.
What fraction of the party size sub did each person get after all the parts were shared out? Briefly explain your reasoning.
Answer:
less sub
if there is less, then you could also divide it into 20 pieces, and give 4 pieces per friend

A house plan shows a scale of 1:40. If the rectangular lounge room of the house is to measure 4.5 metres by 6.3 metres, What are the dimensions of the room on the plan?
Answer:
.112 m by .157m OR 4.43 by 6.20 in
Step-by-step explanation:
The scale is 1:40, meaning that if the house plan shows 1 of something, the real life version is 40 times larger. Given this information:
4.5 m by 6.3 m is the ACTUAL SIZE.
Given this, we need to divide by 40 to get the room PLAN.
0.1125 by 0.1575 meters, OR 4.42913386 by 6.2007874 inches.
Simplifed,
.112 m by .157m OR 4.43 by 6.20 in

$650. During
Sale it is marked
Idown 35%. What is
the sale price of the
bike?
I need the process as well, Please answer fast!!!
Answer:
$422.50
Step-by-step explanation:
Given the following question:
35% of 650
To find the answer we must first calculate 35% of 650 by using the formula to calculate percentages. Then we will subtract that answer from the original price of the bike, which will give us our answer.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{35\times650}{100}[/tex]
[tex]35\times650=22750[/tex]
[tex]22750\div100=227.5[/tex]
[tex]=227.50[/tex]
Now subtract from the original price:
[tex]650[/tex]
[tex]650-227.5=422.5[/tex]
[tex]=422.50[/tex]
The bike after a 35% markdown will cost "$422.50."
Hope this helps.
