Answer: D
Step-by-step explanation:
We will try it to determine how much the need to save using the exponential function. In an exponential function,we need the start up amount and the common difference.
We know that the common difference is is 1.085 because if they will earn 8.5% interest plus 100% .
So 1.085 raised to the number of years times a number has to equal 250,000
x * 1.085^14 = 250,000 now solve for x
3.13340357495x = 250,000
x = 79785.44544 Rounded to the nearest cent is $79785.45

Seventy-five (75) customers at Crummy Burger today were entered in a drawing. Three names will be drawn, and each will win a prize. Determine the number of ways that the prizes can be distributed if all 3 prizes are a $10 gift card.
Answer:
the number of ways in which the prizes are allocated is 67,525
Step-by-step explanation:
Given that
Number of customers = 75
Number of prizes = 3
And, the value of gift card = $10
Based on the above information,
The number of ways in which the prizes are allocated is shown below:
[tex]=^{75} C_3[/tex]
= [tex]\frac{75!}{(3!\times(75-3)!}[/tex]
After solving this the number of ways that came is 67,525
hence, the number of ways in which the prizes are allocated is 67,525
the slope-intercept form of an equation is y = mx + b. rewrite the equation in terms of the slope m
Answer:
[tex]\displaystyle m=\frac{y-b}{x}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]y=mx+b[/tex]
And we want to rewrite it in terms of m.
We can subtract b from both sides:
[tex]y-b=mx[/tex]
Finally, dividing both sides by x yields:
[tex]\displaystyle m=\frac{y-b}{x}[/tex]
In conclusion:
[tex]\displaystyle m=\frac{y-b}{x}[/tex]

A freight train, traveling at a speed of 18.0 m/s, begins braking as it approaches a train yard. The train's acceleration while braking is –0.33 m/s2 . What is the train's speed after 23s?
Answer:
v = 10.41 m/s
Step-by-step explanation:
using one of the equations of motion:
v = u + at
where v= final velocity
u= initial velocity
a = acceleration
t = time
u = 18.0 m/s
v = ?
a = –0.33 m/s2
t = 23s
v = 18.0 + (–0.33 x 23)
v = 18.0 + (-7.59)
v = 10.41 m/s
Shandra is on vacation and wants to buy souvenirs for at least eight friends. A postcard book costs $2.50 and a magnet costs $4.00. She can spend up to $30 all together. Which system of inequalities represents the situation?
Answer:
[tex]2.5p + 4m \leq 30[/tex]
Step-by-step explanation:
Given
Poster = $2.50
Magnet = $4.00
Amount = Up to $30
Required
Determine the inequality
Represent posters with p;
This implies that she can buy 2.50p worth of posters
Represent magnets with m
This implies that she can buy upto 4m worth of magnets
The question says she can spent up to $30;
This implies that she can spend at most $30 and this can be mathematically represented as [tex]\leq 30[/tex]
Bringing the parameters together; we have
[tex]2.5p + 4m \leq 30[/tex]
The system of inequalities that represents the situation is [tex]2.5x+4y\leq 30[/tex] and this can be determined by using the given data and arithmetic operations.
Given :
A postcard book costs $2.50 and a magnet costs $4.00.Shandra can spend up to $30 all together.Let the total number of postcards be 'x' and the total number of magnets be 'y'. The following steps can be used to determine the inequalities that represent the situation:
Step 1 - Multiply 2.5 with x.
2.5x
Step 2 - Multiply 4 with y.
4y
Step 3 - Now, add the above two expressions.
2.5x + 4y
Step 4 - Now, apply the inequality.
[tex]2.5x+4y\leq 30[/tex]
The system of inequalities that represents the situation is [tex]2.5x+4y\leq 30[/tex].

PLEASE HELP ME!!. The local store where Tim shops charges 7% sales tax for clothing. Complete the table by figuring the cost of jeans after sales tax is applied. The first row has been done for you
Step-by-step explanation:
for 1 jeans
7% tax=7/100×25.68
=1.7976
So 1.7976$ is charged on one jeans.
7% tax for 2 jeans =2×1.7976
=3.5952$
Total price=3.5952+25.68
=29.2752
7% tax for 3 jeans=3×1.7976
=5.3928
Total price=5.3928+25.68
=31.0728
Hope this answer will help you
Answer:
$51.36
$77.04
Step-by-step explanation:
Multiply the cost of the number of pairs of jeans by the sales tax amount, 7%.
cost of 2 pairs: 48 + 7/100 x 48 = $51.36
cost of 3 pairs: 72 + 7/100 x 72 = $77.04

Answer:
x = -1/3 - 3/2y
Step-by-step explanation:
Step 1: Write out equation
3y + 2x = -1
Step 2: Subtract 3y on both sides
3y - 3y + 2x = -1 - 3y
2x = -1 - 3y
Step 3: Divide both sides by 2
2x/2 (-1 - 3y)/2
x = -1/3 - 3/2y
Answer:
Hey there!
3y+2x=-1
2x=-3y-1
x=-3/2y-1/2

If Jesse wants to buy a $75,000 10-year term life insurance policy, and the annual premium rate (per $1000 of face value) for his age group is $2.34, how much is Jesse’s annual premium?
Step-by-step explanation:
Since it is given that it costs $2.34 for every $1000 face value, and it was given that he wanted to buy a $75000 plan, multiplying $2.34 by 75 (75000 includes 75 $1000 face value), it should yield us the annual premium.
2.34 * 75 = $175.50
We don't need to multiply it by 10 years as only the annual premium is being solved for.

What are irrational numbers?Irrational number, any real number that cannot be expressed as the quotient of two integers.
How to find which expressions given equal a rational number?Firstly, we know that π is an irrational number .
So π x √4 = 2π
2π is an irrational number and so option A cannot represent a rational number.
