We know, Circumference = <span>π * Diameter
So, c = </span><span>π * 8
c = 8</span><span>π

In short, Your Answer would be Option C

Hope this helps!</span>

B(n)=−4−2(n−1)<br> What's the 12th term in the sequence?

marysya [2.9K]

The 12th term in the sequence is -26.

Given,

B (n) = -4 – 2(n – 1)

We have to find the 12th term in the sequence:

To find the nth term in an arithmetic sequence:

An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d. The common difference, or d, is the difference between any two consecutive terms in an arithmetic series; it can be calculated by deducting any pair of terms starting with a and an+1.

Here,

First term, a = -4

Common difference, d = -2

nth term = 12

Now, let’s find 12th term

B(n) = -4 -2(n – 1)

B(12) = -4 – 2(12 – 1)

B(12) = -4 -2(11)

B(12) = -4 -22

B(12) = -26

That is, the 12th term in the sequence is -26.

An object is thrown upward at a speed of 96 feet per second by a machine from a height of 14 feet off the ground. The height of

liberstina [14]

Answer:

$8t^2 -48 t -7=0$

$x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}$

Where:

a= 8, b =-48, c = -7 and replacing we got:

$t_1 = \frac{48 - \sqrt{(-48)^2 -4(8)(-7)}}{2*8} = -0.1425$

$t_2 = \frac{48 + \sqrt{(-48)^2 -4(8)(-7)}}{2*8} = 6.142$

And since the time cannot be negative the correct answer for this cae would be t = 6.142 s

Step-by-step explanation:

If the question is: When will the object hit the ground at when the time is how many seconds?

We have the function for the heigth given by:

$h(t) = -16t^2 +96 t +14$

And we want to find the time where $h(t) =0$ so we can set like this the condition:

$0 =-16t^2 +96 t +14$

And we can rewrite the expression like this:

$16t^2 -96 t -14 =0$

We can divide both sides of the equation by 2 and we got:

$8t^2 -48 t -7=0$

And we can use the quadratic equation to solve for t like this:

$x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}$

Where:

a= 8, b =-48, c = -7 and replacing we got:

$t_1 = \frac{48 - \sqrt{(-48)^2 -4(8)(-7)}}{2*8} = -0.1425$

$t_2 = \frac{48 + \sqrt{(-48)^2 -4(8)(-7)}}{2*8} = 6.142$

And since the time cannot be negative the correct answer for this cae would be t = 6.142 s
