Step-by-step explanation:
Arithmetic sequence: An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k.
Arithmetic series : An arithmetic series is the sum of a sequence in which each term is computed from the previous one by adding (or subtracting) a constant
Difference: A sequence is defined as an arrangement of numbers in a particular order. On the other hand, a series is defined as the sum of the elements of a sequence.
How to use them : maybe
Geometric Sequence : A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
Geometric series : In mathematics, a geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.
Difference: A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.In mathematics, a geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.
How to use: maybe
Arithmetic and geometric difference: The main difference between arithmetic and geometric sequence is that arithmetic sequence is a sequence where the difference between two consecutive terms is constant while a geometric sequence is a sequence where the ratio between two consecutive terms is constant.
Average rate of change : To find the average rate of change, we divide the change in the output value by the change in the input value.
Sigma notation :Often mathematical formulae require the addition of many variables Summation or sigma notation is a convenient and simple form of shorthand used to give a concise expression for a sum of the values of a variable.
Graph: A continuous function allows the x-values to be ANY points in the interval, including fractions, decimals, and irrational values. A discrete function allows the x-values to be only certain points in the interval, usually only integers or whole numbers.

In your own words, explain the steps you would need to take to find a slope from data in a table.
Answers
Answer:
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
Step-by-step explanation:
Answer:
To Find the slope of a data table, you first need to plot two points on the line. It is easiest if the points are on a coordinate with whole numbers (i.e. (3,6 and (4,8)). Once you have plotted two pints, you then need to take the value of the point with the largest x value, and subtract the other points from it (i.e. (4,8)-(3,6)=(1,2). Then, take the new y value, and divide it by the new y-value (i.e. (2/1), and you have your slope.
Step-by-step explanation:
plot points (3,6), (4,8)
subtract points (4,8)-(3,6)=(1,2)
divide new points 2/1
m=2/1, or 2

O persoană avea 1200 lei și a cheltuit 15% din ei pentru o camașă si 40% din ei pe o pereche de pantofi.Ce sumă i-a rămas?
Answers
Answer:
540 lei
Step-by-step explanation:
Pasul 1
Suma cheltuită pe cămașă se calculează astfel:
1200 lei × 15%
= 1200 lei × 15/100
= 180
Pasul 2
Suma cheltuită pentru o pereche de pantofi se calculează astfel:
1200 lei × 40%
= 1200 lei × 40/100
= 480 lei
Pasul 3
Suma rămasă este calculată ca:
Suma totală - (Suma cheltuită pe cămașă + Suma cheltuită pe încălțăminte)
1200 lei - (180 + 480) lei
1200 lei - 660 lei
= 540 lei

Answers
Answer:
NO. Emma is not correct.
Step-by-step explanation:
✔️Initial value for Function A:
The initial value is the y-intercept of the graph. The y-intercept is the point at which the line intercepts the y-axis. From the graph given, the line intercepts the y-axis, at y = 2, when x = 0.
Initial value for Function A is therefore = 2
✔️Initial Value of Function B:
To find the initial value/y-intercept for Function B, do the following:
Using two pairs of values form the table, (2, 2) and (4, 3), find the slope:
Slope (m) = ∆y/∆x = (3 - 2) / (4 - 2) = 1/2
Slope (m) = ½
Next, substitute (x, y) = (2, 2) and m = ½ into y = mx + b, to find the intial value/y-intercept (b).
Thus:
2 = ½(2) + b
2 = 1 + b
2 - 1 = b
1 = b
b = 1
The initial value for Function B = 1
✅The initial value for Function A (2) is not the same as the initial value for Function B (1). Therefore, Emma is NOT CORRECT.

Lucas is borrowing money to purchase a vehicle. A car dealership will loan Lucas $18,000 with a simple interest rate of 14.5% applied annually, and a 5-year payout plan. The bank will loan Lucas $18,000 with a compound interest rate of 8.9% applied annually and a 4-year payout plan. What is the difference in the total payback amounts?
Answers
Answer:
Difference in total payback = $5734.64
Step-by-step explanation:
Formula for the simple interest payout,
Interest = [tex]\frac{P\times r\times t}{100}[/tex]
P = Principal amount of loan
r = rate of interest (Annually)
t = Duration for the payment
Interest = [tex]\frac{18000\times 14.5\times 5}{100}[/tex]
= $13050
Total payable amount = 18000 + 13050
= $31050
Formula for the amount payable with compound interest,
Final amount = [tex]\text{Initial amount}(1+\frac{r}{n})^t[/tex]
Here, t = Duration of investment
r = rate of interest (Annual)
n = Number of compounding per year
Payable amount = [tex]18000(1+\frac{0.089}{1})^4[/tex]
= 18000(1.089)⁴
= $25315.36
Difference in total payback = $31050 - $25315.36
= $5734.64
If Lucas takes the 5-year payment plan he will end up paying $31,050. If Lucas takes the 4-year payment plan he will end up playing $24,408. Hope it helps.

Answer: In explanation
Step-by-step explanation: 350-170=4x
Solve 180=4x
45=x 45 minutes longer
4x+170=350 because you would want to subtract 170 from each side not add 170 to each side when simplifying
4x+170 because that is how much gas the tank can hold. You need to have 4x in the equation and 350 and 4x wouldn't make sense so use 4x and 170.

I will brainliest if correct! The graph of an exponential model in the form y=aXb^x passes through the points (3,5) and (4,10). Which point is also on the graph?(Multiple choice)
Answers
Answer:
The fourth choice.
Step-by-step explanation:
An exponential function passes through (3, 5) and (4, 10).
And we want to determine which other point is also on the graph.
First, we can find the exponential function. A standard exponential function is in the form:
[tex]y=a(b)^x[/tex]
The point (3, 5) tells us that y = 5 when x = 3. Thus:
[tex]5=a(b)^3[/tex]
The point (4, 10) tells us that y = 10 when x = 4. Thus:
[tex]10=a(b)^4[/tex]
In the first equation, we can divide both sides by a:
[tex]\displaystyle \frac{5}{a}=b^3[/tex]
And we can rewrite the second equation:
[tex]\displaystyle 2(5)=a(b^4)\Rightarrow 2\Big(\frac{5}{a}\Big)=b^4[/tex]
Substitute:
[tex]2b^3=b^4[/tex]
Divide:
[tex]b=2[/tex]
Using the first equation again, substitute:
[tex]5=a(2)^3[/tex]
Simplify and solve:
[tex]5=a(8)\Rightarrow \displaystyle a=\frac{5}{8}[/tex]
So, our exponential function is:
[tex]\displaystyle y=\frac{5}{8}(2)^x[/tex]
Next, we can simply try each point and see which point is correct.
Testing the first point (remember that (2,0) means that y = 0 when x = 2):
[tex]\displaystyle 0\stackrel{?}{=}\frac{5}{8}(2)^0=\frac{5}{8}(1)=\frac{5}{8}\neq 0[/tex]
Testing the second point:
[tex]\displaystyle 1\stackrel{?}{=}\frac{5}{8}(2)^2=\frac{5}{8}(4)=\frac{5}{2}\neq 1[/tex]
The third point:
[tex]\displaystyle 15\stackrel{?}{=}\frac{5}{8}(2)^5=\frac{5}{8}(32)=5(4)=20\neq 15[/tex]
And the fourth point:
[tex]\displaystyle 20\stackrel{?}{=}\frac{5}{8}(2)^5=\frac{5}{8}(32)=5(4)=20\stackrel{\checkmark}{=}20[/tex]
Therefore, D is the correct choice.

If there is 45 ml of milkshake left .She used 1 part strawberry cream to 4 parts milk .How many ml of milk is left?
Answers
Given:
Remaining milkshake = 45 ml
She used 1 part strawberry cream to 4 parts milk.
To find:
The remaining amount of milk.
Solution:
It is given that, she used 1 part strawberry cream to 4 parts milk. It means the ratio of strawberry cream and milkshake is 1:4.
Let the remaining amount strawberry cream be x and the remaining amount of milk is 4x. Then,
[tex]x+4x=45[/tex]
[tex]5x=45[/tex]
[tex]x=\dfrac{45}{5}[/tex]
[tex]x=9[/tex]
Now, the remaining amount of milk is:
[tex]4x=4(9)[/tex]
[tex]4x=36[/tex]
Therefore, the remaining amount of milk is 36 ml.

8300 dollars is placed in an account with an annual interest rate of 6.5%. How much will be an account after 14 years, to the nearest cent?
Answers
Answer:
$ 20,043.46
Step-by-step explanation:
Answer:
A = $ 20,043.46
A = P + I where
P (principal) = $ 8,300.00
I (interest) = $ 11,743.46
Calculation Steps:
First, convert R percent to r a decimal
r = R/100
r = 6.5%/100
r = 0.065 per year,
Then, solve our equation for A
A = P(1 + r/n)nt
A = 8,300.00(1 + 0.065/1)(1)(14)
A = $ 20,043.46
Summary:
The total amount accrued, principal plus interest,
from compound interest on an original principal of
$ 8,300.00 at a rate of 6.5% per year
compounded 1 times per year
over 14 years is $ 20,043.46.
