Help me pls Represent the arithmetic series using the recursive formula.

Mathematics

lesantik [10]3 years ago

Answer:

Option C) is correct

That is the given arithmetic sequence represents the recursive formula is f(n)=f(n-1)+(-5)

Step-by-step explanation:

The given arithmetic sequence is {\{94,89,84,79,...}\}

Let f(1)=94,f(2)=89,f(3)=84,...

To find the common difference d :

d=f(2)-f(1)  ,

=89-94

=-5

Therefore d=-5

d=f(3)-f(2)  ,

=84-89

=-5

Therefore d=-5

Therefore the common difference d=-5

check the recursive formula  f(n)=f(n-1)+d which represents the given arithmetic sequence

Put n=2  and d=-5 in f(n)=f(n-1)+d we get

f(2)=f(2-1)+(-5)

=f(1)-5

=94-5

Therefore f(2)=89

Put n=3  and d=-5 in f(n)=f(n-1)+d we get

f(3)=f(3-1)+(-5)

=f(2)-5

=89-5

Therefore f(3)=84

and so on

Therefore the recursive formula f(n)=f(n-1)+d where d=-5

Therefore the recursive formula f(n)=f(n-1)+(-5)  represents the given arithmetic sequence

What are the possible rational roots of the polynomial equation?<br><br> 0=2x7+3x5−9x2+6
RoseWind [281]

Answer: \pm\frac{1}{1}, \pm\frac{1}{2},\pm\frac{2}{1},\pm\frac{3}{1}, \pm\frac{3}{2}

Step-by-step explanation:

We can use the Rational Root Test.

Given a polynomial in the form:

a_nx^n +a_{n- 1}x^{n - 1} + … + a_1x^1 + a_0 = 0

Where:

- The coefficients are integers.

- a_n is the leading coeffcient (a_n\neq 0)

- a_0 is the constant term a_0\neq 0

Every rational root of the polynomial is in the form:

\frac{p}{q}=\frac{\pm(factors\ of\ a_0)}{\pm(factors\ of\ a_n)}

For the case of the given polynomial:

2x^7+3x^5-9x^2+6=0

We can observe that:

- Its constant term is 6, with factors 1, 2 and 3.

- Its leading coefficient is 2, with factors 1 and 2.

 Then, by Rational Roots Test we get the possible rational roots of this polynomial:

\frac{p}{q}=\frac{\pm(1,2,3,6)}{\pm(1,2)}=\pm\frac{1}{1}, \pm\frac{1}{2},\pm\frac{2}{1},\pm\frac{3}{1}, \pm\frac{3}{2}

Please answer my Questions I have Summative Assessment math
Reil [10]

Answer:

a. Yes

b. 3x+7

c. 105 cm

Step-by-step explanation:

a. a(1)+b=10

   a(2)+b=13

when you solve this by elimination or simultaneously: a=3 and b=7

∴ f(x)=3x+7

b. f(x)=3x+7

c. 3(35)+7=112 cm
