Answer:
recursive: a[1] = 7440; a[n+1] = a[n] -120explicit: a[n] = 7440 -120(n -1)Step-by-step explanation:
The sequence of amounts in Jackson's account will be ...
7440, 7320, 7200, ...
with a first value (a1) of 7440 and a common difference (d) of -120.
The recursive formula for an arithmetic sequence is ...
a[1] = a1
a[n+1] = a[n] +d
For our sequence, the recursive formula is ...
a[1] = 7440
a[n+1] = a[n] -120

Which value of x satisfies the equation 5(2x-9)+3=-7
Answer:
x = 7 / 2
Step-by-step explanation:
5(2x - 9) + 3 = -7 ---------- subtract 3 from both sides
5(2x - 9) + 3 - 3 = -7 - 3
5(2x - 9) = -10 ------ divide both side by 5
2x - 9 = -2 ---------- add 9 to both sides
2x - 9 + 9 = -2 + 9
2x = 7
x = 7 / 2

Juan is interested in the chance of rain for the upcoming week based on studying prior weather data for this time of year. Juan wants to know about what?
Answer:
time and weather data is dis right
Step-by-step explanation:
Step-by-step explanation:
Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere at a given place and using meteorology to project how the atmosphere will change.
Once calculated by hand based mainly upon changes in barometric pressure, current weather conditions, and sky condition or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric factors into account.[1] Human input is still required to pick the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases. The inaccuracy of forecasting is due to the chaotic nature of the atmosphere, the massive computational power required to solve the equations that describe the atmosphere, the error involved in measuring the initial conditions, and an incomplete understanding of atmospheric processes. Hence, forecasts become less accurate as the difference between current time and the time for which the forecast is being made (the range of the forecast) increases. The use of ensembles and model consensus help narrow the error and pick the most likely outcome.
There is a vast variety of end uses to weather forecasts. Weather warnings are important forecasts because they are used to protect life and property. Forecasts based on temperature and precipitation are important to agriculture, and therefore to traders within commodity markets. Temperature forecasts are used by utility companies to estimate demand over coming days. On an everyday basis, many use weather forecasts to determine what to wear on a given day. Since outdoor activities are severely curtailed by heavy rain, snow and wind chill, forecasts can be used to plan activities around these events, and to plan ahead and survive them. In 2009, the US spent approximately $5.1 billion on weather forecasting.[2]

the ratio of the side length of square A to the side length of square B is 3 : 5. the perimeter of square B IS 60 feet. what is the area of square A?
Answer:
81 square ft
Step-by-step explanation:
square B has a site lenght of 15ft
therefore square must have one of 3/5 of 15 which is 9
the area is 9x9=81
given FH with coordinates F(4,-5) and H(-8,19), if G lies on FH such that that the ratio of FG to FH is 1:6, find the coordinates of G
Answer:
G = (2, -1)
Step-by-step explanation:
You want ...
FG/FH = 1/6 = (G -F)/(H -F)
H -F = 6(G -F)
H +5F = 6G . . . . . . add 6F, simplify
G = (H +5F)/6 . . . . .divide by 6
Substituting the given coordinates, we get ...
G = ((-8, 19) +5(4, -5))/6 = (-8+20, 19 -25)/6 = (12, -6)/6
G = (2, -1)

One airplane is located 200 km north and 50 km east of an airport. A second plane at the same altitude is located 30 km north and 100 km north and 100 km west.
The distance between the planes is closest to:
A. 150 km
B. 200 km
C. 300 km
D. 350 km
E. 400 km
Answer:
B. 200 km
Step-by-step explanation:
You can use the Pythagorean theorem for this question. First, you must find a and b. You can do this by finding the distance between North and South, and East and West. For this specific equation, you'd use 200 North - 30 North to get 170 miles on the y-axis. Then, you'd do 50 East + 100 West to get 150 kilometers distance on the x-axis. Now that you have 170 and 150, you can begin the equation
170^2 + 150^2 = c^2
28900 + 22500 = c^2
51400 = c^2
√51400 = √c^2
~226 = c
They are approximately 226 kilometers apart, and 226 is closest to 200, which is B.
While writing this, I felt like I wasn't explaining well. Please feel free to ask for clarification if you need.
The distance between the planes is closest to 200km
You can use the Pythagorean theorem for this question.
First, we need to find a and b. This is gotten by calculating the distance between North and South, and the East and West. From the question, we can say that, 200 North - 30 North gives 170 miles with respect to the y-axis. In the same vein, we know that 50 East + 100 West gives us 150 kilometers which is with respect to the x-axis.
Since we have found our a and b to be 170 and 150, we then use Pythagoras to find the answer to the equation.
170² + 150² = c²
28900 + 22500 = c²
c² = 51400
c =[tex]\sqrt{51400}[/tex]
c = ±226 km.
Since we can't have distance in negative, then our answer is 226 km. The answer asked us to find the closest distance, and thus, our answer is 200km.

An angle measures 28° less than the measure of its complementarylangle. What is the
measure of each angle?
Answer:
59 degrees and 31 degrees.
Step-by-step explanation:
Complementary angles form a 90 degree angle. Let's say that one angle measures x degrees. If one angle is x degrees, the other measures 28 degrees less. So, the other measures x - 28 degrees.
x + (x - 28) = 90
2x - 28 = 90
2x = 118
x = 59 degrees.
The other angle measure will then be 59 - 28 = 31 degrees.
Hope this helps!
Answer:
59° and 31°
Step-by-step explanation:
Complementary angle sum 90°
a + b = 90
a = b - 28
then:
(b - 28) + b = 90
2b - 28 = 90
2b = 90 + 28
2b = 118
b = 118/2
b = 59°
a = b - 28
a = 59 - 28
a = 31°
Probe:
59° + 31° = 90°
Which of the following is not something you should consider when evaluating an investment advisor? a. Their experience b. Whether or not they are registered with FINRA c. Whether or not they are registered with the SEC d. Their educational background
Answer: Whether or not they are registered with FINRA.
Step-by-step explanation: When evaluating an investment advisor, it is important to evaluate their level of experience, educational background as it goes a long way in giving clients a clue of the advisors possible offering, knowledge and expertise. Additionally, an Investment advisor should be registered with the Security and Exchange Commission (SEC), which is a federal regulatory agency charged with making regulatory policies that aid investor protection and proper market functioning. Being registered with FINRA, Financial Industry Regulatory Authority is not really to be considered as it is a self regulatory body (that is non governmental) and the main rules and policies guiding the market are made by SEC.

Lea left home and drove toward the ferry office at an average speed of 22 km.H. Trevon left at the same time and drove in the opposite direction with an average speed of 43 km/h. How long does Trevon need to drive before they are 65 km apart?
Answer:
1 hour
Step-by-step explanation:
Lea's speed = 22km/hr
Trevon's speed = 43km/hr in a direction opposite Lea's
How long does Trevon needs to drive before they are 65km apart.
Note : both took at the same time and in opposite direction.
Recall : speed = distance / time
Distance = speed * time
Distance between them = 65km
Let Trevon's distance = D2 = 43 * t
Lea's distance = D1 = 22 * t
t is the same since they both left at the same time.
D2 + D1 = 65
43t + 22t = 65
65t = 65
t = 65/65
t = 1 hour

Draw a conclusion from the given information. look at picture...
Thanks! Please help soon! :)
Hey there! I'm happy to help!
When looking for a conclusion, we have to find something that we can figure out from the information but they don't directly tell us.
Answer B says that a conclusion is that the lines meet at a 90 degree angle, but they already told us that, so this is wrong.
Answer C does the same thing, so it is wrong as well.
A 90 degree angle is a right angle. They already told us that the lines intersect at a right angle, so this is not a conclusion.
Answer A says that the lines are perpendicular. They don't directly tell us that these specific lines are perpendicular, but from the information they gave us we can figure it out. Therefore, the correct answer is A. The lines are perpendicular.

a)
The rotation transformations are:
[tex] x=x' \cos \theta - y' \sin \theta\\
y= x' \sin \theta + y' \cos \theta[/tex]
where $(x', y')$ are new coordinates.
Since we want an anti-clockwise rotation of the axes, put $\theta= 90$° to get the required coordinates as $(4,-1)$
b)
The equation of the given line is $x-y=0$
Use the mirror formula:
[tex] x'= x_o - \frac{2 a}{a^2+ b^2}(a x_o + by_o +c)[/tex]
Replace $x$ by $y$ above to get the corresponding formula for the y-coordinate.
Here we have
$a=1$
$b=-1$
$c=0$
$x_o= 1$
$y_o =4$
Substitute these values to get the required coordinates as $(4,1)$
c)
$(5,3)$ maps onto $(1,1)$
Let's keep it simple here: To get the new coordinates you subtract 4 from the x coordinate and 2 from the y coordinate.
Thus for our point $(1,4)$ our image is $(1-4, 4-2)$ which is $(-3,2)$

find the slope (0, -3) and (9, 0) PLEASE SHOW YOUR WORK, WILL MARK BRAINLEIST
===================================================
Work Shown:
Use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (0 - (-3))/(9 - 0)
m = (0 + 3)/(9 - 0)
m = 3/9
m = 1/3
----------------
Basically we subtract the y coordinates, and do the same for the x coordinates as well (subtract in the same order). Afterward, divide the two results. Reduce the fraction as much as possible.
A slope of 1/3 means we move up 1 unit each time we move to the right 3 units.
The slope being positive means the line goes uphill as you read from left to right.
You are a caterer specializing in children's birthday parties. You have 12 birthdays to cater next week. You must bake 2 cakes for each party. Each cake will have 6 candles on it. How many birthday candles do you need for the 12 parties.
Answer:
We need 144 birthday candles do you need for the 12 parties.
Step-by-step explanation:
We are given that you are a caterer specializing in children's birthday parties. You have 12 birthdays to cater to next week. You must bake 2 cakes for each party. Each cake will have 6 candles on it.
And we have to find the birthday candles we need for the 12 parties.
AS it is stated that next week you have 12 birthday parties and for each birthday party you must bake 2 cakes.
This means that for 12 birthday parties you have to make = [tex]12 \times 2[/tex] = 24 cakes.
Also, each cake has 6 candles on it. This means that the total number of candles for 24 cakes = [tex]24 \times 6[/tex] = 144 candles.
Hence, we need 144 birthday candles for the 12 parties.
