A sequence is defined by the term-to-term rule
U = + 2
Given that u, = -3,
a) find u,
b) find uz
Answer:
Please check the explanation.
Step-by-step explanation:
a)
A sequence is defined by the term-to-term rule such as
[tex]U_{n+1}=U^3_n+2[/tex]
Given that
[tex]U_0=-3[/tex]
Substituting n = 0 to determine u₁
[tex]U_{0+1}=U^3_0+2[/tex]
[tex]U_1=U^3_0+2[/tex]
substituting [tex]U_0=-3[/tex]
[tex]U_1=\left(-3\right)^3+2[/tex]
[tex]U_1=-27+2[/tex]
[tex]U_1=-25[/tex]
Therefore,
[tex]U_1=-25[/tex]b)
[tex]U_{n+1}=U^3_n+2[/tex]
Substituting n = 1 to determine u₂
[tex]\:U_{1+1}=U^3_1+2[/tex]
substituting [tex]U_1=-25[/tex]
[tex]U_2=\left(-25\right)^3+2[/tex]
[tex]U_2=-15625+2[/tex]
[tex]U_2=-15623[/tex]
Therefore,
[tex]U_2=-15623[/tex]

Did the same result occur in both parts when you held up a lighted splint to the jar's mouth?
What can you conclude from this about the identity of the gas(es) in Parts 1 and 2? (3
points)
Answer:
Oxygen gas causes a glowing splint to continue burning. If you observe a gas forming, test for its identity by inserting a glowing wood splint into the mouth of the test tube. Light the splint and then blow out the flame, leaving a glow.
Bill charges $12 per hour for a plumbing job. Write the equation that shows the relationship between the numbers of hours Bill work's,h, and the amount of money he makes, m?
Answer:
m = 12h
Step-by-step explanation:
Since Bill charges $12 per hour, it implies for every hour he charges $12. Therefore, the amount of money he makes, m, is dependent on the number of hours he works, h. The higher the number of hours, the more his money. And vice versa.
So that;
m = 12h
Thus if Bill works for 6 hours, his amount of money would be;
m = 12 (6)
= 72
m = $72
Bill would make $72 after working for 6 hours.

Which number line represents the solutions to -2x| = 4?
O 2o 2 4 6 & 10
-i0 -862 0 2 4 6 & 10
-10 -8 -6 -4-2 0 2 4 6 8 10
Answer:
graph c
Step-by-step explanation:
Given
| - 2x | = 4
The absolute value function always gives a positive result, however, the expression inside can be positive or negative , that is
- 2x = 4 or - (- 2x) = 4
Solving both
- 2x = 4 ( divide both sides by - 2 )
x = - 2
or
- (- 2x) = 4
2x = 4 ( divide both sides by 2 )
x = 2
The third graph indicates x = - 2 and x = 2 on the number line
Solve for x in the equation x2 + 20x+100= 36.
Answer:
-16, -4
Step-by-step explanation:
x² +20x +100 -36 = 0
x² +20x +64 = 0
x² -Sx +P =0, where S= sum of roots, P=product of roots
so what 2 numbers have
S= -20 and P = 64 , ...that ul be -4, -16
or you can use factoring:
( x+16) ( x+4) = 0
x+16 = 0 , x= -16
x+4 =0, x = -4
or you can do quadratic equation, or graph ...
Answer: The Answer is:
Fraction form: x= -32/11
Decimal form: x= -2.90909....
Step-by-step explanation:
1. Add similar elements: 2x+20x=22x
22x+100=36
2. Subtract 100 from both sides:
22x+100-100=36-100
3. Simplify:
22x=-64
4. Divide both sides by 22:
22x÷22=-64÷22
5. Your Answer:
x= -32/11
What is the image of the point (-6,-8) after a rotation of 90° counterclockwise about the origin?
Answer:
(6,-8)
Step-by-step explanation:
By rotating the point (-6,-8) Counterclockwise you get the point (6,-8)
Hope it helps
The new coordinates after rotation will be - P'(8, -6)
We have a Point on a X - Y plane as P(-6, -8) which is rotated by 90° counter clockwise about the origin.
We have to determine the image of this point after the rotation.
What do you understand by Rotation of a Point in X - Y plane?
A rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.
According to the question, we have -
A point with coordinates → P(-6, -8)
Any point (say A[x, y]) when rotated 90° counter clockwise about the origin, then its new coordinates become A'(-y, x).
Using this rule, the coordinates of the point after rotation of point by 90° counter clockwise about the origin will be → P'(8, -6)
Hence, the new coordinates will be - P'(8, -6)

Give the equation for this line in
slope-intercept form.
slope = -2, y-intercept = 5
y ]
= [?]x + []
Answer:
y = -2x + 5
Step-by-step explanation:
The equation of a line is y = mx + c where m is the slope and c is the y-intercept. Since we already know the values, we can just put it into the equation.
y = mx + c
y = -2x + 5
Answer:
y = - 2x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2 and c = 5 , thus
y = - 2x + 5 ← equation of line

Please help very urgent! :)
Answer:
y = - 0.05x - 1.9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
y = 20x ← is in slope- intercept form
with slope m = 20
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{20}[/tex] = - 0.05 , thus
y = - 0.05x + b ← is the partial equation
To find b substitute (2, - 2) into the partial equation
- 2 = - 0.1 + b ⇒ b = - 2 + 0.1 = - 1.9
y = - 0.05x - 1.9 ← equation of perpendicular line

A builder is building a fence with 6 LaTeX: \frac{1}{4}1 4 inch-wide wooden boards, arranged side-by-side with no gaps. How many boards are needed to build a fence that is 150 inches long?
Answer:
24 boards
Step-by-step explanation:
From the above question, the width of a wooden board for a fence = 6 1/4 inches
How many boards are needed to build a fence that is 150 inches long?
This is calculated as:
6 1/4 inches = 1 board
150 inches = x
Cross Multiply
6 1/4 × x = 150 × 1
x = 150 ÷ 6 1/4
x = 150 ÷ 25/4
x = 150 × 4/25
x = 24 boards
Hence, 24 boards would be needed to build a fence that is 150 inches long

The graph shows the amount of money left after buying video games. Find the slope of the line
Answer:
It’s -20
Step-by-step explanation:
The slope of the line is m = -20.
What is the slope?The ratio of the vertical and horizontal changes between two points on a surface or a line is known as the slope.
Note that the graph passes through points (2,80) and (4,40).
The formula for the slope of a line passing through the points (x₁,y₁) and (x₂,y₂) is:
m = (y₂-y₁)/(x₂-x₁)
Substitute the points (x₁,y₁) = (2,80) and (x₂, y₂) = (4,40) into the above equation:
m = (40 - 80)/(4 - 2)
m = -40/2
m = -20
Hence, the slope of the line is m = -20.

What is the equation for the graph?
Answer:
Standard Form:
[tex]y = {x}^{3} - 3 {x}^{2} + 3x - 4[/tex]
Another Form:
[tex]y = (x - 1)^{3} - 3[/tex]
Step-by-step explanation:
The type of graph or function is called Cubic Function
The type of graph is represented by the equation of y = a(x-h)³+k
Thus our equation for the graph is
[tex]y = {(x - 1)}^{ 3} - 3[/tex]
In case if you want standard form.
Simplify the expression.
[tex](x - y)^{3} = {x}^{3} - 3 {x}^{2} y + 3x {y}^{2} - {y}^{3} [/tex]
[tex]y ={x}^{3} - 3 {x}^{2} + 3x - 1 - 3 \\ y = {x}^{3} - 3 {x}^{2} + 3x - 4[/tex]
A wireless company offers two cell phone plans. For the month of September Plan A charges $35 plus $0.25 per minute for calls. Plan B charges $20 plus $0.50 per minute for calls. For what number of minutes do both plans cost the same amount?
i really need help
Answer:
3.75 minutes
Step-by-step explanation:
Set up an equation where x is the number of minutes:
0.25x + 35 = 0.5x + 20
Solve for x:
0.25x + 35 = 0.5x + 20
35 = 0.25x + 20
15 = 0.25x
3.75 = x
So, both plans will cost the same with 3.75 minutes
