7 days in 1 week....so 91 days = (91/7) = 13 weeks
and there are 52 weeks in 1 yr

so in weeks, it took 13/52 which reduces to 1/4 <==

Find the standard form of the equation of the parabola with a focus at (0, -3) and a directrix at y = 3. (5 points)
OLEGan [10]

Answer:

From given option ,  the equation of parabola is                                            y = negative x² divided by 12

Step-by-step explanation:

Given as for parabola :

The focus is at (0 , - 3)

The directrix equation is y = 3

Now, equation of parabola parallel to y-axis is

( x - h )² = 4 p ( y - k )

where focus is ( h , k+p )   and  directrix equation is y = k - p

So, from equation

h  = 0     and   k + p = - 3

And y = k - p   i.e k - p = 3

Now solving  ( k + p ) + (  k - p ) = - 3 + 3

or, 2 k = 0  ∴ k = 0

Put the value of k , k + p = - 3

So, 0 + p = - 3    ∴ p = - 3

Now equation of parabola with h = 0  , k = 0  , p = - 3

( x - h )² = 4 p ( y - k )

I.e ( x - 0 )² = 4 × ( - 3 ) ( y - 0 )

Or, x² = - 12 y   is the equation of parabola

Hence  From given option ,  the equation of parabola is                                y = negative x² divided by 12       Answer

Reagan has a savings account that earns 1.87% interest, compounded quarterly. If she needs $20,857 for a down payment on a house
MatroZZZ [7]
To solve this, we are going to use the compounded interest formula: A=P(1+ \frac{r}{n} )^{nt}
where 
A is the final amount after t years
P is the initial investment 
r is the interest rate in decimal form 
n is the number of times the interest is compounded per year
t is the time in years

We know from our problems that she needs $20,857 for a down payment on a house in 9 years, so A=20857 and t=9. To convert the interest rate to decimal form, we are going to divide the rate by 100%
r= \frac{1.87}{100} =0.0187
Since the interest is compounded quarterly, it is compounded 4 times per year; therefore, n=4. 
Lets replace the values in our formula to find P:
A=P(1+ \frac{r}{n} )^{nt}
20857=P(1+ \frac{0.0187}{4} )^{(4)(9)}
P= \frac{20857}{(1+ \frac{0.0187}{4} )^{(4)(9)}}
P= \frac{20857}{(1+ \frac{0.0187}{4} )^{36}}
P=17633.17

We can conclude that the correct answer is: <span>B. 17,633.17</span>

A retail shop accepts only cash or checks suppose that 45% of its customers carry cash 44% carry checks and 31% carry both cash
sergejj [24]

Answer:

Step-by-step explanation:

The number of customers carrying cash=45% = 0.45

The number of customers carrying checks= 44% =0.44

The number of customers carrying both = 31% = 0.31

So,

To find the probability we will write the expression:

cash+checks-cash or checks(both)=cash and checks

0.45+0.44-both=0.31

0.45+0.44-0.31=both

0.58=both....

You want to have $40,000 for a down payment on a house 4 years from now. if you can earn 5.6 percent, compounded annually on you
NeX [460]
You need a compound interest formula solved for principal:
Principal = Total ÷ (1 + Rate)<span> ^ years
</span><span>
Principal = 40,000,/ (1.056) ^ 4
</span><span><span><span>Principal = 40,000 / 1.2435282985 </span> </span> </span>
Principal = <span> <span> <span> 32,166.54 </span> </span> </span>
So, 32,166.54 deposited for 4 years at 5.6% interest (compounded annually) produces $40,000.
