What is the value of the fourth term in a geometric sequence for which ay = 10 and r = 0.5?

Answer:

1.25

Step-by-step explanation:

a = 10 and r = 0.5

The formula for calculating any term in a geometric sequence is a (the first term) times r (the common ratio) raised to the power of n - 1.

In this case n = 4, since we're looking for the fourth term.

so,

Un = ar^n-1

= ar^4-1

= ar^3

U4 = 10 × 0.5^3

= 10 × 0.125

= 1.25

                  Find the circumference of the circle and show work. [refer to  

                  attachment]

\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

          Formula for Circumference of a Circle:-

        \dashrightarrow\star\bigstar\boxed{\boxed{C=2\pi r}}}

Where

  • C = circumference
  • π = pi (3.14…)
  • r = radius, which in this case is equal to 8

Substitute the value of r and solve:-

         C=2π(8)

        On simplification,

     

C=16π

On further simplification,

C=50.3

Therefore, we conclude that the circumference of this circle is

\dashrightarrow\star\bigstar\boxed{\boxed{\underline{\bold{C=50.3\:yd}}}}\bigstar\star\dashleftarrow

<h3>Good luck.</h3>

Determine and state the vertex of f(x) = x2 - 2x - 8 using the method of completing the square
Elza [17]

Answer:

vertex = (1, - 9 )

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = x² - 2x - 8

To complete the square

add/ subtract ( half the coefficient of the x- term )² to x² - 2x

f(x) = x² + 2(- 1)x + 1 - 1 - 8

     = (x - 1)² - 9 ← in vertex form

with vertex = (1, - 9 )

A stone fell from the top of a cliff into the ocean.
Nikitich [7]

Answer:

5 seconds.

Step-by-step explanation:

Make an equation.

Time in air = x

Time in water = 12 - x

16x + 36 - 3x = 127

13x = 91

x = 7

12 - 7 = 5
