The recursive function LaTeX: f\left(0\right)=1,\:f\left(n\right)=f\left(n-1\right)+2nf ( 0 ) = 1 , f ( n ) = f ( n − 1 ) + 2 n represents
Question:
The recursive function [tex]f(0) = 1[/tex], [tex]f(n) = f(n-1) + 2n[/tex] represents the nth term of a sequence. Determine the explicit function
Answer:
[tex]f(n) = n^2 + n+1[/tex]
Step-by-step explanation:
Given
[tex]f(0) = 1[/tex]
[tex]f(n) = f(n-1) + 2n[/tex]
Required
Write an explicit formula
Let n = 1
[tex]f(1) = f(1-1) + 2*1[/tex]
[tex]f(1) = f(0) + 2[/tex]
[tex]f(1) = 1 + 2 = 3[/tex]
Let n = 2
[tex]f(2) = f(2-1) + 2*2[/tex]
[tex]f(2) = f(1) + 4[/tex]
[tex]f(2) = 3 + 4 = 7[/tex]
Let n =3
[tex]f(3)=f(3-1) + 2 * 3[/tex]
[tex]f(3)=f(2) + 6[/tex]
[tex]f(3)=7+ 6 = 13[/tex]
Let n = 4
[tex]f(4) = f(4 - 1) + 2 * 4[/tex]
[tex]f(4) = f(3) + 8[/tex]
[tex]f(4) = 13+ 8 = 21[/tex]
So, we have:
[tex]f(1) = 3= 1 + 2 * 1=1+0*1*2*1[/tex]
[tex]f(2) = 7= 3 + 2 * 2=1+1*2+2*2[/tex]
[tex]f(3) = 13= 7 + 2 * 3= 1+2*3+2*3[/tex]
[tex]f(4) = 21 = 13 + 2 * 4= 1+3*4 +2 *4[/tex]
Following the above pattern:
[tex]f(n) = 1 + (n - 1) * n + 2 * n[/tex]
[tex]f(n) = 1 + n(n - 1) + 2n[/tex]
Open bracket
[tex]f(n) = 1 + n^2 - n + 2n[/tex]
[tex]f(n) = 1 + n^2 + n[/tex]
[tex]f(n) = n^2 + n+1[/tex]
solve -4x^2+3x=-5 using quadratic formula
Answer:
Step-by-step explanation:
Here, we want to solve the given quadratic equation using the quadratic formula
We need to rewrite the equation in the standard form;
-4x^2 + 3x + 5 = 0
we have the value a as -4
value b as 3
C = 5
we then substitute these values into the quadratic formula as seen in the attachment

The circumference of a circle is approximately 131.88 centimeters What is the area of the shaded region (6/10 of a circle)
Answer:
82.97cm^2
Step-by-step explanation:
Given data
Circumference= 131.88 centimeters
We want to find the area of 6/10 part of a circle
Firstly, let us find the area of the circle
We need to get the radius
C= 2πr
131.88= 2*3.142*r
131.88=6.284r
r= 131.88/6.284
r=20.98 cm
Area= πr^2
Area= 3.142*20.98^2
Area= 3.142*440.16
Area= 1382.98cm^2
Hence 6/10 of a 1382.98
=0.06*1382.98
=82.97cm^2

explain why 8.0 is greater then 0.8
Answer:
since the eight in the second number is to the right of the decimal, and there id no other number on the left, the second number isn't even a whole number. It is four fifths of a whole. while the eight in the first number is to the left of the decimal it is a whole number eight times. like, which is more eight cookies or a part of one cookie.

Henry's dinner bill is $132 the sales tax of 10% he lives at it of 15% how much will I pay in tax how much does it pay in tip what is his total bill
Answer:
$165
Step-by-step explanation:
Dinner bill = $132
Sales tax = 10% of dinner bill
Tip left = 15% of dinner bill
Amount of sales tax :
10% of $132
0.1 * $132 = $13.2
Amount of tip left :
15% * $132
0.15 * $132 = $19.8
Total bill :
Dinner cost + sales tax + tip
$132 + $13.2 + $19.8
= $165

Jim Tree sells trees. The mean length of the trees purchased was 68 inches with a standard deviation of 10 inches. Jim wants to know what percent of his sales were more than 84 inches tall. He can use the standard normal distribution to help him.
Answer:
Follows are the solution to this question:
Step-by-step explanation:
Given value:
[tex]\to X = 84\\\\\to \mu = 68\\\\\to \sigma= 10\\\\[/tex]
Using formula:
[tex]\bold{Z= \frac{X-\mu}{\sigma}}[/tex]
[tex]= \frac{84-68}{10}\\\\ = \frac{16}{10}\\\\=1.6[/tex]
Calculating the percent of the sales which is less than or equal to 84 inches:
[tex]\to P(Z \leq 1.6)=0.9452[/tex]
[tex]= 0.9452 \times 100\\\\ =94.52\% \approx 95.5\%[/tex]
Calculating the remaining value [tex]100-94.5=5.5\%[/tex] were more than 84 inches.

I=$200,p=$1000,r=4 years
Answer:
idt this is right..... sorry if this is wrong...
Step-by-step explanation:
I = $ 8,000.00
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 200%/100 = 2 per year,
then, solving our equation
I = 1000 × 2 × 4 = 8000
I = $ 8,000.00
The simple interest accumulated
on a principal of $ 1,000.00
at a rate of 200% per year
for 4 years is $ 8,000.00.
