1 = 1/16 (one chance on 16

2 = 7/16 (the non shaded parts are 7, while the total parts are 16)

3 = 11/16 ( 11 is unshaded + even)

You get a gift of $1,000.  You decide that you want to invest all of the money in a savings account.  However, your bank has two different savings plans.  Determine the final amount in the account for each plan in 5 years.  Round your answers to two decimal places if needed. 
 
Plan A:  The bank gives you 4% interest rate and it is compounded every two months.  
 
Plan B:  The bank gives you a 10% interest rate and compounds the interest every 6 months.

Final Account balance for Plan A: $ 
 
Final Account balance for Plan B: $

Answers

So you basically get 104% of your Savings Account every two months for Plan A.

Plan B makes it 110% of your Savings Account every 6 months. Now we just calculate it...I'm sure your allowed a calculator, so just do 110% of it till 5 years.

If you still don't understand I can explain it more.

Answer:

AC = 15.6

Step-by-step explanation:

AC = AE + EC

By he Pythagorean theorem,

A² + B² = C²

12² + 5² = AE²

144 + 25 = AE²

AE = √169

AE = 13

Find Angle AED

tan Angle AED = 12/5

Angle AED = tan-1 (12/5)

= 67.38°

Angle AED = Angle BEC

tan (67.38°) = BC/1

BC = 2.4

1² + 2.4² = EC²

6.76 = EC²

EC = √6.76

EC = 2.6

AC = 13 + 2.6

AC = 15.6

Answers

Answer:

Step-by-step explanation:

Range is y thing, where as domain is an x thing. The way you state a range (or a domain, for that matter) is to start from the low point on the graph and go up to the high point. Our graph doesn't have a starting point; therefore, the "low" end of the graph comes up from -∞. The high point on the graph maxes out at 3. Therefore, the proper way to state the range (depending upon whether you use set-builder or not) is

R = (-∞, 3] or another way to state this is

R = {y | y ≤ 3} which reads "y such that y is less than or equal to 3".

Step-by-step explanation:

Given

The temperature on Monday was [tex]-5^{\circ}C[/tex]

By Tuesday, it becomes [tex]-2^{\circ}C[/tex]

Change in temperature is the difference between the two temperatures.

[tex]\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C[/tex]

Does anyone know how to solve this?

Answers

Given :

A right angle triangle ABC .

To Find :

The perimeter of ABC .

Solution :

Since, triangle ABC is right angled and angle ∠ABC is 46° .

So, AC = AB cos 46° = 7.64 units.

Also, CB = AB sin 46° = 7.91 units.

Therefore, the perimeter of ΔABC is :

P = 11 + 7.64 + 7.91 units

P = 26.55 units

Hence, this is the required solution.

Factor completely 18x2 − 21x −15. 3(2x + 1)(3x − 5) 3(2x − 5)(3x + 1) 3(2x − 1)(3x + 5) 3(6x + 1)(x − 5)

Answers

Answer:

3(2x + 1)(3x - 5)

Step-by-step explanation:

Given

18x² - 21x - 15 ← factor out 3 from each term

= 3(6x² - 7x - 5 ) ← factor the quadratic

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 6 × - 5 = - 30 and sum = - 7

The factors are + 3 and - 10

Use these factors to split the x- term

6x² + 3x - 10x - 5 ( factor the first/second and third/fourth terms )

3x(2x + 1) - 5(2x + 1) ← factor out (2x + 1) from each term

(2x + 1)(3x - 5)

Then

18x² - 21x - 15 = 3(2x + 1)(3x - 5)

Answer:

A

Step-by-step explanation:

Consider this equation
3x+ 1=2x-5

Answers

Answer: x=-6

Step-by-step explanation:

Add 5 to both sides to get 2x by itself

Yes, subtract 1 from both sides to get 3x by itself so you can subtract 2x as to not get a negative x value

One common mistake would be to accidentaly adding or subtracting 1 or 5 when they are supposed to be added/subtracted. To avoid this just go back and check your awnser by plugging it in.
