The answer would be C. If you simplify the 12/9 by 3 it would simplify to be 4/3 and 4/3 = 4/3. You can also cross multiply 4/3 = 12/9. 4(9) = 12(3) both would equal 36 so they would be proportional.

What is the solution set of 4x^2 -5x +1 =0

goblinko [34]

Answer:

Step-by-step explanation

Answer:

4x^2-5x+1=0

=4x^2-x-4x+1=0

The second 4x is because of 5x=-x-4x

=xmultiply(4x-1)-4x-1)=0

=(4x-1)x(x-1)=0

=4x-1=0

Another value for x is

x-1=0

Final

=x=1/4

=x=1

Finally the answers are

Value of first X is

X=1/4

Value of second X is

X=1

GEOMETRY, HELP. 50 points.

Rus_ich [418]

Answer:

Part A.

w = √(d^2 - l^2)

Part B.

w = 6ft

Step-by-step explanation:

length l = 8ft

diagonal d = 10ft

width w = ?

we can see it as a Trangle, so using a Pythagorean theorem,

d^2 = l^2 + w^2

w = √ (d^2 - l^2)

w = √ (10^2 - 8^2)

w = √ (100 - 64)

w = √ 36

w = 6

Find the explicit formula for the geometric sequence cn given below. Note that c1=6.

kodGreya [7K]

The explicit formula for the geometric sequence $c_{n}$ is

$c_{n}=6(\frac{-1}{3})^{n-1}$

Step-by-step explanation:

The formula of the nth term of a geometric sequence is

$a_{n}=a(r)^{n-1}$ , where:

a is the first term of the sequence
r is the common ratio between the consecutive terms

The geometric sequence of $c_{n}$ is 6 , -2 , $\frac{2}{3}$ , $\frac{-2}{9}$ , $\frac{2}{27}$

∵ $c_{1}$ = 6

∵ $r=\frac{c_{2}}{c_{1}}$

∵ $c_{2}$ = -2

∴ $r=\frac{-2}{6}$

- Divide both term by 2 to simplify it

∴ $r=\frac{-1}{3}$

∵ $c_{n}=c_{1}(r)^{n-1}$

- Substitute the value of $c_{1}$ and r in the rule above

∴ $c_{n}=6(\frac{-1}{3})^{n-1}$

The explicit formula for the geometric sequence $c_{n}$ is

$c_{n}=6(\frac{-1}{3})^{n-1}$
