Answer:
−8[tex]n^{2}[/tex]
Step-by-step explanation:
Hey there
Steps :
-n x 8n
Apply the exponent rule : [tex]a^{b} * a^{c} = a^{b + c}[/tex]
[tex]-n = -n^{1}[/tex]
[tex]n = n^{1}[/tex]
[tex]-8n^{1+1}[/tex]
add the numbers: 1+1
[tex]-8n^{1+1} = -8n^{2}[/tex]
Which of the following is a Recursive Formula for an Arithmetic Sequence?
a1 = -2, an = an-1 + 5
an = 5n – 7
a1 = -2, an= 5an-1
an = -2 + 5(n – 1)
Answer:
The correct answer is Option 1: a1 = -2, an = an-1 + 5
Step-by-step explanation:
A recursive formula is a formula that uses previous term in order to calculate the next term in a sequence.
In case of arithmetic sequence, the next term is obtain by adding a specific number to the last term.
This can be written as:
[tex]a_n = a_{n-1}+d[/tex]
Here
a_n is the terms we are calculating
a_{n-1} is the previous term and d is the common difference.
If we compare the given options, we can see that only option 1 matches with the general form of recursive formula
an = an-1 + 5
Here
5 is the common difference
Hence,
The correct answer is Option 1: a1 = -2, an = an-1 + 5

what is the vetical change on a graph called
Answer:
Its called the rise
Step-by-step explanation:
1. The ratio of boys to girls is 4/5. If there
are 24 boys, how many girls are there?
Given:
The ratio of boys to girls is [tex]\dfrac{4}{5}[/tex].
Number of boys = 24
To find:
The number of girls.
Solution:
We have,
Boys: Girls = 4:5
Let the number of boys be 4x and number of girls be 5x.
[tex]4x=24[/tex]
[tex]x=\dfrac{24}{4}[/tex]
[tex]x=6[/tex]
Now,
Number of girls = [tex]5x[/tex]
= [tex]5(6)[/tex]
= [tex]30[/tex]
Therefore, the number of girls is 30.

what is the Y interpret of the question? y=-1/2x-6
Answer:
The y-intercept is (0,-6)
Step-by-step explanation:
In the equation y = mx + b, b is the y-intercept. In your equation, the b is -6, so the y-intercept is (0,-6).
Answer:
Y-intercept: (0, -6)
Step-by-step explanation:
We have to determine the "y-intercept" in the equation.
The equation is written out in slope-intercept form: y = mx + b
The "b" variable would be our y-intercept, or beginning point.
In the y = -1/2x-6 equation, you would see that the "-6" is in place of the "b" variable.
Therefore, the y-intercept of the line would be (0, -6).
Alina is moving into a two-bedroom apartment in Downtown Tampa. The monthly rent is $2,000. Her up-front fees are shown. How much can she expect to pay up-front for this apartment? Round to the nearest dollar.
Application fee: 3% of one month's rent
Credit application fee: $20
Security deposit: 1 month's rent and last month's rent
Broker's fee: 14% of year's rent
Answer:
7440
Step-by-step explanation:
3%×2000=60
60+20=80
2000+2000=4000
4000+80=4080
14%×24000=3360+4080=7440

Noah's oven thermometer gives a reading that is 2% greater than the actual temperature.
If the actual temperature is 325°F, what will the thermometer reading be?
Round your answer to the tenths (first) decimal place.
Do not include units (°F) in your answer.
PLS HELP
357 I think is the right answer.Since the thermometer reading was 7°F greater than 350. The thermometer reading is 359+7=357
Jean's bedroom is 13 feet by 13 feet. She has chosen a carpet which costs $28.60 per square yard. This includes installation.
Answer:
$528.8
Step-by-step explanation:
Given data
Dimension
13 feet by 13 feet
1 ft =4.3 yard
Area= 4.3^2
Area= 18.49 yard
cost of carpet
1 yard= $28.60
18.49 yard= x
cross multiply
x= 18.49*28.60
x=$528.8
Hence the cost to cover the room is $528.8

what value(s) of x will make x to the 2nd power =9 true
Answer:
x = 3 , X = -3
In x 2 = 9 , you need to get rid of the power of 2 in order to isolate just x This involves finding the square root. √ x 2 = x However there are 2 possible answers to a square root, a positive or a negative answer. x = ± √ 9 x = ± 3

Plz help me and hurry
Answer:
A. For each input value, x, there is exactly one output value, y.
Step-by-step explanation:
A function always have exactly one output value (y-value) that is related or assigned to each input value (x-value), however, two different x-values can have the same y-value.
In the graph given, although two different values have the same y-value, every x-value has exactly one y-value corresponding to it. No x-value has two different y-values.
Therefore, the graph represents a function.

What is −3x+4y=−16 in slope-intercept form?
Answer:
y=3/4x-4
Step-by-step explanation:
First you put x to the other side of the equation, so you have 4y = 3x-16. Next you need to get y alone so you get 4y/4=y. But, you need to do this to both sides of the equation, so you do 3x-16/4=3/4x-4. All in all, your slope-intercept form is y=3/4x-4.
