$144104.88 Bill have at the end of the twentieth year if he can earn 12 percent on his contributions.

Given that,

For the next 20 years, Bill intends to contribute the maximum $2,000 each year to his individual retirement account (ira).

We have to find how much will Bill have at the end of the twentieth year if he can earn 12 percent on his contributions.

We know that,

The worth of repeated payments at a specific future date, less a specified refund rate or a discount rate, is known as the future annuity value. The annuity amount increases with the discount rate.

According to the information provided, Future Value of Annuity equals:

FV= A×[(1+r)ⁿ-1]/r

Here,

A is periodic payment

r is rate per period

FV is future value

n is number of period

FV=2000×[(1+0.12]²⁰-1]/0.12

FV=2000×72.05244

FV=$144104.88

Therefore, $144104.88 Bill have at the end of the twentieth year if he can earn 12 percent on his contributions.

Answer:

Step-by-step explanation:

The coefficient of an algebraic expression (-x+3) corresponds to the number that precedes (or multiplies) the variables in it 1.

1. The functions are the same because each of the function has equations that are modeled after the horse diving into the water.

2. Given t = 20s, so using the equation modeled for Seb, we have

h(20) = -16(20^2) + 16(20) +18

After evaluating it we get -6062ft which is not possible since we cannot get a height in negative and jumping off at a height of 6062ft if it was in positive it wouldn't be done by a sane person.

3. Putting the value of t as 0 in the equation we get,

h(0) = -16(0^2) + 16(0) + 18

After evaluating it, we get 18ft and in this situation, we can say that in 0 seconds that is when the horse had not yet dived, the horse was at a height of 18ft.

4 a. Taking the value of h as 18 in Sabri's equation, we get

18 = -16(t - 0.5)^2 + 22

18 = 16t^2 - 4 + 22            (After solving {t - 0.5}^2)

t^2= 18 + 4 - 22/ 16

t^2= 0

t = 0seconds

b. The maximum height of Sabrina's height was 18ft, since this is the initial height of the horse diving booth.

What are functions?
In mathematics, a function is an expression, rule, or law that establishes a relationship between an independent variable and a dependent variable. To put it simply, a function is a type of rule that produces one output for every input it receives. Here, y=x2 serves as an illustration. A single output for y results from any input for x. Since x is the input value, we would state that y is a function of x.

The answer that 12 times 1/3 will equal to -4 to 0, solving an equation.

What is an Equations?

Equations are mathematical statements with two algebraic expressions on either side of an equals (=) sign. It illustrates the equality between the expressions written on the left and right sides. To determine the value of a variable representing an unknown quantity, equations can be solved. A statement is not an equation if there is no "equal to" symbol in it. It will be regarded as an expression.

So the equation 12(x)-4 = 0

⇒12*x =4

⇒x=4/12

Answer:

Theusage is 585 minutes of call duration..

Explanation:

Fixed plan cost is M=$.39.95

Charge for first 500 minutes call: Free

Charge for call exceeding 500 minutes: $.0.35/minutes.

Let x minutes be the total call duration.

The bill is P=$.69.70 i.e. more than $.39.95, which indicates

call duration is more than 500 minutes.

The rule states that bill for call exceeding 500 minutes is

P=M+(x−500).0.35 or

69.70=39.95+(x−500).0.35 or (x−500).0.35=69.70−39.95 or

(x−500).0.35=29.75 or (x−500)=

0.35

Step-by-step explanation:

I assume you need the slope-intercept form

y = ax + b

"a" being the slope, "b" being the y-intercept (the y value when x = 0).

since we have the slope and a point, we can start with the point-slope form

y - y1 = a(x - x1)

"a" is again the slope, (x1, y1) is a point on the line

so, we have

y - -7 = 3(x - -4)

y + 7 = 3(x + 4) = 3x + 12

and from there now the final equation :

y = 3x + 5

Answer:

∴ Shaquana bought 7 candies and 6 pretzels.

Step-by-step explanation:

Suppose all the snacks she bought were candies.

13 × $5 = $65

$65 - $53 = $12

$5 - $3 = $2

$12 ÷ $2 = 6 pretzels

∴ Number of candies Shaquana bought

= 13 snacks - 6 pretzels

= 7 candies

Answer:

6 pretzels and 5 candies

Step-by-step explanation:

Let c be the number of candies and p the number of pretzels.

We can determine the total cost by multiplying the candy price by it's price, $5/candy.  That would be $5*c.  We can do the same for the pretzels:  $3*p.

Thje total spent is:    ($5)c + ($3)p = $53.  Since the $ sign cancels out, let's rewrite this to simplify:   5c + 3p = 53.

We know that c + p = 13

Rearrange this to c = 13-p and then substitute this definition of c in the first equation:

5c + 3p = 53

5(13-p) +3p = 53

65 - 5p + 3p = 53

-2p = - 12

p = 6  Shaquana brought 6 pretzels.

Since c + p = 13, this means she bought 7 candies.

Check to see if this works:

Do 6 pretzels and 7 candies cost $53?

 (6 prezels)*($3/pretzel) =  $18

 (7 candies)*($5/candy) =  $35

               Total                =  $53  YES

A polynomial function with zeros of -1, -1, 2i is:

f(x) = x^3 + (2 - 2i)x^2 + (1 - 4i)x - 2i

We have been given a polynomial function with zeros of -1, -1, 2i

This means, (x + 1), (x + 1) and (x - 2i) are roots of polynomial.

Let f(x) be required polynomial function.

To find a polynomial consider an equation,

f(x) = 0

(x + 1) * (x + 1) * (x - 2i) = 0

(x^2 + 2x + 1) * (x - 2i) = 0

x(x^2 + 2x + 1) - 2i(x^2 + 2x + 1) = 0

x^3 + 2x^2 + x - 2ix^2 - 4ix - 2i = 0

x^3 + (2 - 2i)x^2 + (1 - 4i)x - 2i = 0

so, f(x) = x^3 + (2 - 2i)x^2 + (1 - 4i)x - 2i

Therefore, a polynomial with zeros of -1, -1, 2i is f(x) = x^3 + (2 - 2i)x^2 + (1 - 4i)x - 2i

Answer:

Answer:

[tex]\frac{1}{120}[/tex]

Step-by-step explanation:

To solve such a problem you need to simulate a situation in which this could happen in three picks and then make sure your equation takes into account that all three picks take place at the same time. One such situation could look like this:

1) At the start, the probability of picking one rotten apple with one pick is 2 out of 16 which 2/16.

2) After picking the first apple you have 15 apples left of which only 1 is rotten. So the chance to pick the second rotten apple is 1/15.

3) After you picked the second rotten apple you want the third one in the set to be good. As you are left with 14 apples of which all 14 are good, the probability of picking a good one is 14/14.

Now, because you are interested in ALL those 3 things happening at the same time, you need to multiply the probabilities. So this gives you the answer of:

[tex]\frac{2}{16} *\frac{1}{15} *\frac{14}{14} = \frac{1}{8} *\frac{1}{15} *1 = \frac{1}{120}[/tex]

You can achieve the same result if your picks are in a slightly different order. The result won't change as long as the outcome is the same (set of 2 rotten apples and 1 good apple). So if you first pick a rotten apple (2/16), then you happen to pick a good apple (14 out of 15 left are good so 14/15) and then pick the second rotten apple last (1/14) you will see it's gives the same result because you also end up with 2 rotten and 1 good apples:

[tex]\frac{2}{16} * \frac{14}{15} * \frac{1}{14} = \frac{1}{8} * \frac{1}{15} = \frac{1}{120}[/tex]

Our given expression:  " -2(3²)³ " ;  is the same as:
  " - 2* (3²)³ " ;   We have parentheses, exponents, and multiplication;

 So; we need to find the value of:  " (3²)³ " ;  

and multiply that value by -2 ;

 So, let's start with calculating:  " (3²)³ " ;

Method 1)
 " (3²)³ = (3* 3)³ = 9³ = 9 * 9 * 9 = (9 * 9) * 9 = 81 * 9 = 729 " .

Method 2)
Note the multiplication property of exponents:
 (aᵇ)ᶜ = a⁽ ᵇ *ᶜ ⁾ ;

As such:   "  (3²)³ =  3⁽²*³⁾ = 3⁶ " ;

                             =  3 * 3 * 3 * 3 * 3 * 3 ;          

                             =  (3 * 3) * 3 * 3 * 3 * 3 ;

                             =   (9 * 3) * 3 * 3 * 3 ;

                            =   (27) * 3 * 3 * 3 ;

                             =   (27)  *  (9)* 3 ;\
