Set up the characteristic equation, which is given by r2 − 5r − 6 = 0. The roots of this equation are given by r1 = 6 and r2 = −

s344n2d4d5 [400]

Answer:

Step-by-step explanation:

From your characteristic equation, your recursive equation is

$f(n+2) = 5 f(n=1) +6f(n)$

the general solution:

$f(n) = A6^n + B(-1)^n$

The initial conditions are

$f(0) =1 ~~~and~~~ f(1) = 3$

For f(0) = 1, that is

$f(0) = A6^0 + B(-1)^0 = A+ B=1 (*)$

For f(1) = 3, that is

$f(1) = A6^1 + B(-1)^1 = 3$

$6A- B = 3 (**)$

From (*) and (**) you solve for A and B

you have A = 4/7 and B= 3/7

Replace A, B into the general one, you have the particular solution for the given condition

$f(n) = 4/7 *6^n +3/7*(-1)^n$

The second side of a triangular deck is 3 feet longer than the shortest side, and the third side is 3 feet shorter than twice t

Eddi Din [679]

Answer:

The length of the shortest side is 18 ft

The length of the second side is 21 ft

The length of the third side is 33 ft

Step-by-step explanation:

Let

x ------> the length of the shortest side

y -----> the length of the second side

z ----> the length of the third side

we know that

The perimeter of the deck is

P=x+y+z

P=72 ft

72=x+y+z ------> equation A

y=x+3 ------> equation B

z=2x-3 -----> equation C

substitute equation B and equation C in equation A and solve for x

72=x+(x+3)+(2x-3)

72=4x

x=72/4

x=18 ft

Find the value of y

y=18+3=21 ft

Find the value of z

z=2(18)-3=33 ft

therefore

The length of the shortest side is 18 ft

The length of the second side is 21 ft

The length of the third side is 33 ft

A cheetah can run 103 feet per second. A zebra can run x feet per second. Use the distributive property to write and simplify an

Morgarella [4.7K]

Answer:

$(103-x) 10$ ft

Step-by-step explanation:

A Cheetah can run at 103 ft/s.

A Zebra can run at x ft/s.

We have to use distributive property, in the distributive property we multiply a sum by multiplying each addend separately and then add the products.

$a \times (b+c)= a \times b + a \times c$

In ten seconds, Cheetah will cover,

$10 \times 103 = 1030 ft$

In ten seconds, Zebra will cover,

$x \times 10= 10 x ft$

So the distance by which Cheetah is farther than Zebra is,

$1030 - 10x$

= $(103 -x) 10 ft$ (Use of distributive property)
