Answer:

about 27.27 hours.

Step-by-step explanation:

If it can travel 0.11 miles in 1 hour, we need to divide 3 miles by 0.11 miles to get the number of hours it would take to travel 3 miles. 3/0.11 is 27.27 repeating.

Hope this helps!

Answer:

27.27 hours

Step-by-step explanation:

You need to set up a proportion. I did distance over time.

\frac{.11 mi }{1 hr} = \frac{3 mi}{x hr}

Cross multiply

.11x = 3

Divide by .11

x = 27.27

Use the grouping method to factor the polynomial below completely. x3 + 2x2 + 3x + 6
Phoenix [80]

Hello from MrBillDoesMath!

Answer:

(x+2) ( x^2 + 3)

Discussion:

x^3 + 2x^2 + 3x + 6 =  

( x^3 + 2x^2) + (3x + 6) =         => factor "x^2" from the first term; factor 3

                                                    from the second term

x^2( x + 2) + 3( x+2)  =             => factor (x+2) from each term

(x+2) ( x^2 + 3)

Thank you,

MrB

What's the explicit rule for the sequence 3, -6, 12, -24, 48, ...?
777dan777 [17]

Answer:

\sf \dfrac{-3}{2}(-2)^n

Step-by-step explanation:

Explicit formulas are used to represent all the terms of the geometric sequence with a single formula.

  \sf \boxed{\bf t_n = ar^{n-1}}

a is the first term.

r is the common ratio.

r = second term ÷ first term.

   3 , - 6 , 12, - 24, 48 ,........

a = 3

r = -6 ÷ 3 = -2

         \sf t_n = 3*(-2)^{(n-1)}\\\\

             \sf = 3*(-2)^{n}*(-2)^{-1}\\\\ =3*(-2)^n*\dfrac{-1}{2}\\\\= \dfrac{-3}{2}(-2)^n

Check:

\sf t_1 =\dfrac{-3}{2}*(-2)^1=\dfrac{-3}{2}*(-2) = 3\\\\\\t-2 = \dfrac{-3}{2}*(-2)^2 = \dfrac{-3}{2}*4=-6\\\\\\t_3=\dfrac{-3}{2}*(-2)^3=\dfrac{-3}{2}*(-8)=12

What is the slope of the line that contains the points (-2,7) and (2,3)
Ludmilka [50]

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =3\\y_{1} =7\\x_{2} =2\\x_{1} =-2

^^^Plug these numbers into the formula for slope...

\frac{3-7}{2 - (-2)}

\frac{-4}{4} -------------------> Simplifies to -1

                                                ^^^This is your slope

Hope this helped!

sp2606 [1]

Answer:

The answer is the option A

0.5\ ft

Step-by-step explanation:

Let

x-------> the width of the border

we know that

The total area of the window plus the border is equal to

A=2*4+7=15\ ft^{2}

(2+2x)(4+2x)=15\\2*4+2*2x+2x*4+2x*2x=15\\8+4x+8x+4x^{2}=15\\4 x^{2}+12x-7=0

Using a graphing tool -----> to resolve the quadratic equation

see the attached figure

The solution is

x=0.5\ ft
