I use math-way for problems like this its really helpful :)

a=b+cw

-----------------

1+b+cw-w2

(I'm guessing your solving for A tell me if I'm wrong and I will fix it so I don't take your points)

What is the slope intercept form of the equation of the line that passes through the point (-6 ,1) and is perpendicular to the g

Elena-2011 [213]

Answer:

y-1 = 3/2(x+6)

Step-by-step explanation:

slope of equation is -2/3 so to make it perpendicular find the opposite reciprocal: 3/2, that's the new slope, plug in x and y

Luther earned some money doing odd jobs last summer and put it in a savings account that earns 3% interest compounded quarterly

inysia [295]

The function we have to use in this case is

$m(t)=m_o\cdot(1+\frac{0.03}{4})^{4t}$

where mo is the initial amount of money. After 2 teats we get that

$\begin{gathered} m_0\cdot(1+\frac{0.03}{4})^8=800 \\ m_0\cdot1.06=800 \\ m_0=\frac{800}{1.06}\approx754.71 \end{gathered}$

SO he earned 755 approximately

Answer:

$a_{15}=-268,435,456$

Step-by-step explanation:

First, find what factor each term is multiplied by to get to the next. To do this, divide the second term by the first, the third term by the second, etc

$4\div-1=-4\\-16\div4=-4\\64\div-16=-4$

The common factor is 4. Using that, you can now write the equation for the geometric sequence in the form of:

$a_n=a_1x^{n-1}$

It looks scarier than it is. aₙ is the nth term in the sequence, x is the factor, and n is the index in the sequence, that's all it is.

Plug in the information we have to get the equation for this sequence:

$a_n=(-1)(-4)^{n-1}$

Then, you can solve for the 15th term:

$a_{15}=(-1)(-4)^{15-1}\\a_{15}=(-1)(-4)^{14}\\a_{15}=(-1)(268,435,456)\\a_{15}=-268,435,456$

Basically, just raise the scale factor to the power of the term you want minus 1, then multiply that by the first number.

steposvetlana [31]

P(heads) = 1 - 0.4 = 0.6 $P(5\ heads)=7C5\times0.6^{5}\times0.4^{2}=0.2613$
The answer is 0.26 to 2 d.p.
