2 answers:

6 0

First step: subtract 16 from both sides to get x=12-16

Second step: simplify to x= -4

Third step: fill it back into the equation to check, 16 + -4 = 12, and 12=12 this is a true statement

The fourth term of a sequence is 108. Each term after the first is 3 times the previous term. Write an explicit expression that

marishachu [46]

Answer:

$f(n)=4(3)^{n-1}$

Step-by-step explanation:

Let the first term be $x$ , then the terms of the sequence are:

$x,3x,9x,27x,81x,...$ .

Since the fourth term is 108, we have

$27x=108$

$\implies x=4$

Hence the sequence becomes:

$4,12,36,108,324,...$ .

The explicit expression for a geometric expression is given by:

$f(n)=ar^{n-1}$

where a=4 and r=3

The required formula is:

$f(n)=4(3)^{n-1}$

What is the focus of the parabola given by the equation y = x2 − 2x − 3?

erica [24]

What is the focus of the parabola given by the equation y = x2 − 2x − 3?
y = x2 − 2x − 3
y = x2 − 2x − 3 -1 +1y = (x - 1)^2 - 4 h = 1 and k = - 4 and a = 1

Vertex (a, k) so it is (1,-4)

Now focus is
(1, -4 + 1/4) = (1,-3 3/4)
or
(1,-3.75)

x = $\frac{In (2) + In (3)}{In (2) - In (3)}$

Or

x ≈ - 4.41902258

I hope this helps, Good luck!
