Answer:

$187.74\:\mathrm{cm}$

Step-by-step explanation:

The area of a rectangle is given by $l\cdot w$ . Therefore, we can set up the following inequality:

$l\cdot 16 \leq 3,003.84$ .

Solving this inequality, we have:

$l \leq 187.74$ .

Therefore, the largest length Carmen's painting can be is $\fbox{$187.74\:\mathrm{cm}$}$ .

Which statement is true about the equation fraction 3 over 4z = fraction 1 over 4z − 3 + 5?

SashulF [63]

Answer:

It has two solutions.

Step-by-step explanation:

Let as consider the given options are

It has no solution.

It has one solution.

It has two solutions.

It has infinitely many solutions.

The given equation is

$\dfrac{3}{4z}=\dfrac{1}{4z-3}+5$

Multiply both sides by 4z(4z-3).

$3(4z-3)=4z+5(4z(4z-3))$

$12x-9=4z+80z^2-60z$

$0=-12x+9+80z^2-56z$

$0=80z^2-68z+9$

It is a quadratic equation.

Therefore, it has two solutions.

Need help geometric sequences see pic for details

LenKa [72]

Given:

The recursive formula of a geometric sequence is

$a_n=a_{n-1}\cdot (\dfrac{1}{8})$

$a_1=-3$

To find:

The explicit formula of the given geometric sequence.

Solution:

We know that, first term of geometric sequence is $a_1=-3$ .

Recursive formula of a geometric sequence is

$a_n=a_{n-1}\times r$ ...(i)

where, r is common ratio.

We have,

$a_n=a_{n-1}\cdot (\dfrac{1}{8})$ ...(ii)

On comparing (i) and (ii), we get

$r=\dfrac{1}{8}$

The explicit formula of a geometric sequence is

$a_n=a_1r^{n-1}$

Putting $a_1=-3$ and $r=\dfrac{1}{8}$ , we get

$a_n=-3\left(\dfrac{1}{8}\right)^{n-1}$

Therefore, the correct option is D.
