5-(-1) you need to change the negative one to a positive one
5+(+1)then just remove the parentheses and add them up witch gives

Determine whether the sequence below is a geometric sequence and, if so, find a formula that describes the sequence. 1, 3, 9, 27
r-ruslan [8.4K]

a geometric sequence is a bunch of numbers where you can get from a number to the next number by multiplying the previous number by a certain number

might be confusing so here's an example

1,2,4,8,16

each term is multiplied by 2 to get next term, that number that each term is multiplied by is called the common ratio

formula for geometric sequence is

a_n=a_1(r)^{n-1}

where a_n is nth term

a_1 is first term

r is teh common ratio

n=which term


in our example

1,3, 9, 27, 81

each term is being multiplied by 3 so it is a geometric sequence and thus r=3

also first term is 1 so a_1=1

so the formula is a_n=1(3)^{n-1} or in function notation f(n)=1(3)^{n-1}

zzz [600]

Answer:

  • width: 1.9 ft
  • length: 2.3 ft
  • height: 1.7 ft

Step-by-step explanation:

The volume of a rectilinear shape is given by ...

  V = W·L·H . . . . . where W, L, and H represent width, length, and height

Filling in the given information, we want to find a solution to ...

  7.4 = x(x +0.4)(x -0.2)

If we write ...

  f(x) = x(x +0.4)(x -0.2)

Then we're looking for the value of x that satisfies ...

  f(x) -7.4 = 0

The attached graph shows that value to be 1.897, about 1.9 (feet). Then the desired kennel dimensions are ...

  • width: 1.9 ft
  • length: 2.3 ft
  • height: 1.7 ft

Kaliska is jumping rope. The vertical height of the center of her rope off the ground R(t) (in cm) as a function of time t (in s
xz_007 [3.2K]

Answer:

R (t) = 60 - 60 cos (6t)

Step-by-step explanation:

Given that:

R(t) = acos (bt) + d

at t= 0

R(0) = 0

0 = acos (0) + d

a + d = 0 ----- (1)

After \dfrac{\pi}{12} seconds it reaches a height of 60 cm from the ground.

i.e

R ( \dfrac{\pi}{12}) = 60

60 = acos (\dfrac{b \pi}{12}) +d --- (2)

Recall from the question that:

At t = 0, R(0) = 0 which is the minimum

as such it is only  when a is  negative can acos (bt ) + d can get to minimum at t= 0

Similarly; 60 × 2 = maximum

R'(t) = -ab sin (bt) =0

bt = k π

here;

k  is the integer

making t the subject of the formula, we have:

t = \dfrac{k \pi}{b}

replacing the derived equation of k into R(t) = acos (bt) + d

R (\dfrac{k \pi}{b}) = d+a cos (k \pi) = \left \{ {{a+d  \ for \ k \ odd} \atop {-a+d \ for k \ even}} \right.

Since we known a < 0 (negative)

then d-a will be maximum

d-a = 60  × 2

d-a = 120 ----- (3)

Relating to equation (1) and (3)

a = -60 and d = 60

∴ R(t) = 60 - 60 cos (bt)

Similarly;

For R ( \dfrac{\pi}{12})

R ( \dfrac{\pi}{12}) = 60 -60 \ cos (\dfrac{\pi b}{12}) =60

where ;

cos (\dfrac{\pi b}{12}) =0

Then b = 6

∴

R (t) = 60 - 60 cos (6t)
