hopes of earning enough interest to buy a car at a later date. Jarad deposits the entire amount into an account that pays 6.3% interest, compounded weekly. How many weeks must Jarad wait for the investment to reach a value of $6700? Round your answer up to the next complete week and assume that there are exactly 52 weeks in a year.

<h3>Answer:</h3>

242 weeks

<h3>Explanation:</h3>

After n weeks at annual interest rate r, the principal amount P will result in account balance A according to ...

... A = P·(1 +r/52)^n

Taking logs, we get

... log(A) = log(P) +n·log(1 +r/52)

... (log(A) -log(P))/log(1 +r/52) = n . . . . . solve for n

Filling in the given informatin, we have ...

... (log(6700) -log(5000))/log(1 +.063/52) = n ≈ 241.71

Rounded to the next higher number of weeks, this is 242 weeks.

How to divide (x^2+5x-36)÷(x-4)
mr_godi [17]

Answer:

x + 9

Step-by-step explanation:

Since the divisor is in the form of <em>x - c</em>, use what is called <em>Synthetic Division</em>. Remember, in this formula, -c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:

4| 1 5 -36

↓ 4 36

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

1 9 0 → x + 9

You start by placing the c in the top left corner, then list all the coefficients of your dividend [x² + 5x - 36]. You bring down the original term closest to <em>c</em><em>,</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have NO REMAINDER. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an x, and the 9 follows right behind it, giving you the other factor of x + 9.

Tanya says .53 is greater than .7 because 53 is greater than 7 Can you explain her mistake?
sergey [27]
Take 0.53 and 0.7 by 100 to make them percents. 0.53 times 100 is 53% and 0.7 time 100 is 70%. so 0.7>0.53

Marysya12 [62]

For this one add 35 to the -22 degrees.  So the equation is 35+(-22) which would equal 13 degrees F for a high.

Find the exact circumference of a circle with the given radius. 5 inches C = 2.5 in. 10 in. 25 in.
notsponge [240]
If the given radius is 5 inches, then the circumference, C is 2pi r, or 2pi(5 inches) = 10pi inches.  You MUST include pi in your calculation of C.
