Write a recursive formula that defines the following sequence f(1)=1, f(2)=9, f(3)=17, f(4)=25, f(5)=33.

Hello,

I hope you and your family are doing well!

To calculate the amount of interest earned on a savings account, you can use the following formula:

interest = principal * rate * time

In this case, the principal is $9,500, the rate is 3.75%, and the time is 1 year. Plugging these values into the formula, we get:

interest = $9,500 * 3.75% * 1 year = $356.25

So, in a year, Alice would earn $356.25 in interest on her savings account.

Answer:

You draw the line of the graph and every point on the line is a solution

Step-by-step explanation:

y = mx + b  You graph the b which is the y intercept.  This is where the graph crosses the x axis.  In this case it is -12.  From that point (0,-12)  You follow a pattern which is the slope.  In this case the slope is -3.  That mans that you move three units down and then 1 unit right.

I highlighted a few points on the line.  Every point on the line is a solution.

The scientific notation of the wavelength of green light in a spectrum

is 3×10⁻⁶ feet.

In scientific notations numbers are written in the form of a base that is

0  ≤ b < 10 and multiplied by 10ⁿ where n represents integers.

We write large standard numbers in scientific form in a compact manner.

Given, The wavelength of green light in a spectrum is about 0.000003 feet.

Now, the decimal is 6 places before so we have to move the decimal 6 places to the right, and to maintain the actual value we'll raise it to 10⁻⁶.

Therefore, 0.000003 feet,

= 3×10⁻⁶ feet.

So, the wavelength of green light is 3×10⁻⁶ feet.

Answer:

the number of terms N in the series is approximately 8.57, which is approximately equal to 9.

Step-by-step explanation:

The mean of a series is calculated by taking the sum of all the terms in the series and dividing it by the number of terms. In this case, the mean of the continuous series Efm=300+20m is given as x=15+m.

To find the number of terms N in the series, we can use the formula for the mean to solve for N. The formula for the mean is:

mean = sum of terms / number of terms

Substituting the given values, we get:

15+m = (300+20m) / N

We can then multiply both sides of the equation by N to isolate the sum of terms:

(15+m) * N = 300+20m

This simplifies to:

15N + mN = 300 + 20m

We can then combine like terms to get:

(15+20)N = 300

35N = 300

Dividing both sides by 35, we get:

N = 300/35

N = 8.57

Since the number of terms must be a whole number, the number of terms N in the series is approximately 8.57, which is approximately equal to 9.

Answer:-1/2

Step-by-step explanation:

y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

In the perpendicular lines the product of slopes will be -1

m1m2=-1

y=x+4 is the given line, it has slope of 1, so the perpendicular line will have slope -1.

The line is passing through (8,2)

2=-1(8)+b

2=-8+b

2+8=b

10=b

Hence, y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4

Answer:

  (c)  12(2v-7)

Step-by-step explanation:

You want the expression resulting from factoring out the greatest common factor from the sum 24v -84.

The greatest common factor here is the GCF of 24 and 84. We note that ...

  24 = 12·2

  84 = 12·7

and 2 and 7 have no common factors. Then the GCF of 24 and 84 is 12.

The factored expression is ...

  24v -84 = 12(2v -7)

__

Additional comment

The GCF can also be found by considering the remainder from dividing 84 by 24. That remainder is 12, which divides both numbers with a remainder of 0. Hence 12 is the GCF.

If the remainder did not divide both numbers with a remainder of 0, then the process is repeated to find the GCF of the smaller number (24) and the remainder. (This is a description of Euclid's algorithm for finding the GCF.)

Using mathematical operations, we can conclude that both London and Colin will get 1/4 of strawberries each.

A mathematical function known as an operation converts zero or more input values into a precisely defined output value.

The quantity of operands affects the operation's arity.

The four basic mathematical operations, according to the majority of people, are addition, subtraction, multiplication, and division.

So, the strawberries both Landon and Colin will get are:

We know that Landon and Colin brought 1/2 strawberries.

They share is equally that is:

1/2 ÷ 2

Now, solve as follows:

1/2 ÷ 2

1/2 ÷ 2/1

1/2 * 1/2

1/4

Therefore, using mathematical operations, we can conclude that both London and Colin will get 1/4 of strawberries each.

Dilation:

Dilation is the scaling factor multiplied by the supplied line to line ratio.

Given

Line p in the coordinate plane has a y-intercept and a slope of 6. (0, 8). Line p is dilated by a factor of 4 with center to produce line r. (0, 4).

Here, we need to determine line r's slope and y-intercept.

Here, the scaling factor is known to be 4.

Consider the line r's slope, which won't change, and its intercept, which will be their ordinate added.

So, it can be written as,

The number of weeks it will take them to have saved thesame amount is 8 weeks

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time.

if x represents the the number of weeks for saving and y represents the equal saved amount, then

42+16x = y equation 1

-70+ 30x = y equation 2

subtract equation 1 from 2

-70-42+16x- 30x= 0

-112+14x= 0

collect like terms

-112=-14x

divide both sides by 14

x= -112/-14

x= 8weeks

therefore it will take them 8 weeks to have equal savings

y = x - 1

y = 3x + 1

We can use the combine method here.

==> - 1y + 1x = 1  (y = x - 1)

==>  -1y +3x = -1 (y = 3x + 1)

- 1y + 1x = 1  

 -1y +3x = -1

To single out any of the two variables, we need them to cancel out. Let us choose to cancel out y. We therefore multiply by negative 1 in the first re-arranged equation.

==> -1* (- 1y + 1x )= (1 ) * -1

Now we add the equations
