I need help with this problem and please show step by step
Answer:
a).
[tex]{ \bf{first \: term}} \\ let \: n = 1 \\ n_{1} = {1}^{2} + 3(1) + 1 \\ n_{1} = 5 \\ \\ { \bf{second \: term}} \\ let \: n = 2 \\ n_{2} = {2}^{2} + 3(2) + 1 \\ n_{2} = 11 \\ \\ { \bf{third \: term}} \\ n_{3} = {3}^{2} + 3(3) + 1 \\ n_{3} = 19 \\ \\ { \bf{fourth \: term}} \\ n_{4} = {4}^{2} + 3(4) + 1 \\ n_{4} = 29[/tex]
b).
common difference, d:
[tex]d = n_{4} - n_{3} \\ d = 29 - 19 \\ d = 10\\ but \: increases \: by \: 2 \\ d = 10 + 2 = 12\\ therefore : \\ n_{5} = n_{4} + d \\ n_{5} = 29 + 12 \\ n_{5} = 41[/tex]
c).

If there are 3.28 feet in a meter , how many are in the 110 meter dash?
In 110 meter dash, there are 360.8 feet.
What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given that, there are 3.28 feet in a meter
Since,
in 1 meter there are = 3.28 feet
Thus in 110 meters there are = 3.28 * 110 feet
In 110 meters, there are = 360.8 feet
Therefore, there are 360.8 feet in 110 meters dash.

draw the graph of the following equation 2(x+1)=3(y-1)-4
anyone knows how to do this ?
9514 1404 393
Answer:
see attached
Step-by-step explanation:
I find the easiest way to draw a graph is to let a graphing calculator do it. That result is shown in the attachment.
__
If you're drawing this by hand, it can be easier if it is simplified a bit.
2(x +1) = 3(y -1) -4
2x +2 = 3y -3 -4 . . . . . . eliminate parentheses
2x +9 = 3y . . . . . . . . . . add 7
y = 2/3x +3 . . . . . . . . . divide by 3
This is the equation of the line in slope-intercept form. It tells you that the point (0, 3) on the y-axis is on the line, and that it has a slope of 2/3. That means it has a rise/run of 2/3, or a rise of 2 units for each 3 units to the right.
Starting from point (0, 3), another point on the line will be 3 over and 2 up, at (3, 5). Once you have a couple of points plotted, you can draw the line through them to make your graph.

35. The circumference of a circle is 67
inches. What is the area of the circle?
A=2
Answer:
B
Step-by-step explanation:
hopefully it makes sense and is visible:)
====================================================
Work Shown:
C = 2*pi*r .... circumference equation
6pi = 2pi*r .... replace C with the given circle perimeter
6 = 2r .... divide both sides by pi, they cancel
6/2 = r
3 = r
r = 3 ... is the radius
------------
A = pi*r^2 .... area of circle equation
A = pi*3^2
A = pi*9
A = 9pi .... which points to choice B as the final answer

O M ZABC = 60°
OM ABC = 67°
OM ZABC = 120°
O M ABC = 127°
Answer:
∠ ABC = 127°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ABC is an exterior angle of the triangle , then
∠ ABC = ∠ BDC + ∠BCD = 60° + 67° = 127°
We know that we have a triangle and we want to find the value of its angle which will be given by 53°.
We know that the sum of all the interior angles of a triangle must equal 180 degrees, so we find then:
[tex]ABC=180[/tex]
Now making the sum of the angles already known and equating to 180, we find that:
[tex]180=67+60+x\\x=180-127\\x= 53[/tex]

-7x-14=2x+13 What does x equal?
Answer: x = -3
Step-by-step explanation:
Given
-7x - 14 = 2x + 13
Subtract 2x on both sides
-7x - 14 - 2x = 2x + 13 - 2x
-9x - 14 = 13
Add 14 on both sides
-9x - 14 + 14 = 13 + 14
-9x = 27
Divide -9 on both sides
-9x / -9 = 27 / -9
[tex]\boxed {x = -3}[/tex]
Check:
Left-hand side = -7x - 14
= -7 (-3) - 14
= 21 - 14
= 7
Right-hand side = 2x + 13
= 2 (-3) + 13
= -6 + 13
= 7
7 = 7

Answer:
a.
MP3 player: 88%
Video game player: 92%
b.
MP3 player: 75 minutes
Video game player: 67 minutes
Step-by-step explanation:
a.
MP3 player
- Already has 40%
- Each 15 minutes additional 12%
--> An hour = (60/15)*12 = 48 (%)
--> After an hour charged = 40 + 48 = 88%
Video game player
- Already has 20%
- Each 10 minutes additional 12%
--> An hour = (60/10)*12 = 72 (%)
--> After an hour charged = 20 + 72 = 92 (%)
b. To charges 100 minutes:
MP3 player
100 = 40 + ((x/15*12)
--> x = 75 (minutes)
Video game player
100 = 20 + ((x/10*12)
--> x = 67 (minutes)

5a/8ab = ?/ 24a^2 b
9514 1404 393
Answer:
? = 15a^2
Step-by-step explanation:
We assume you want
(5a)/(8ab) = (?)/(24a^2·b)
Multiplying by 24a^2·b, we get ...
(5a)/(8ab)·(24a^2·b) = ? = 15a^2
The sign shows distances from a rest stop to the exits for different towns along a straight section of
highway. The state department of transportation is planning to build a new exit to Freestone at the
midpoint of the exits for Roseville and Edgewood. When the new exit is built, what will be the distance
from the exit for Midtown to the exit for Freestone?
Exit for free stone
(35+51)/286/243miDistance from midtown to free stone
43-1726miThe distance from Midtown to Freestone is 26mi.
What is the distance?The Distance is defined as the product of the speed and time.
Given data as:
Exit for Midtown = 17 mi
Exit for Roseville = 35 mi
Exit for Edgewood = 51 mi
Exit for freestone = (35+51)/2
Exit for freestone = 86/2
Exit for freestone = 43mi
Distance from Midtown to Freestone = Exit for freestone - Exit for Midtown
Distance from Midtown to Freestone = 43 - 17
Distance from Midtown to Freestone = 26mi
Hence, the distance from Midtown to Freestone is 26mi.
