Answer:

Please check explanations for answer

Step-by-step explanation:

Here, we want to check the given list and state the true values;

1. This is true

Compound interest has the exponent nt; simple interest has no exponent

2. This is false

Simple interest is only earned on the principal which is the amount deposited

3. True

Due to its multiplication chain, it earns more money as we can compound more than once within the given time frame

4. This is false; check explanations above

5. This is true

Its value is only based on the amount invested originally

6. This is false

simple interest earns the same amount annually based on rate

7. This is false

Both considers the time factor t in their formulas

8. This is true

The interest and principal forms the principal for another compounding time

What is t in 197sin(12t)=141
spayn [35]

Answer:

  t ≈ 0.0664731

Step-by-step explanation:

Use the inverse sine function.

  sin(12t) = 141/197

  12t = arcsin(141/197)

  t = arcsin(141/197)/12

  t ≈ 0.0664731 . . . . . . . radians

__

This is the principal value. There are other solutions at values of t that have integer multiples of π/6 added to this. There are also solutions where any of those values is subtracted from π.

_____

In general, angles in math are assumed to be in radians, unless specified otherwise. This angle corresponds to about 3.81°. (In geometry, the usual assumption is that angles are measured in degrees.)

morpeh [17]

Amy has $30 to spend on snacks and beverages for herself and her friends at the movie theater. The cost for nachos was $5. The cost for each beverage was half the cost of the nachos

Let x be the number of nachos and y be the number of beverages

The cost for nachos was $5. So the cost of 'x' nachos = 5x

The cost for each beverage was half the cost of the nachos.

The cost of each beverage = \frac{5}{2}= 2.5

so the cost of y beverage = 2.5 y

Cost of x nachos + cost of y beverage = total amount spend

5x + 2.5y = 30

Now we find x  and y intercept

When Amy does not buy any beverages we put y=0

5x + 2.5(0) = 30

5x = 30

x= 6. The x intercept is (6,0)

When Amy does not buy any nachos we put x=0

5(0) + 2.5y = 30

2.5y = 30

y=12. The y intercept is (0,12)

The graph is attached below

(b) The graph is a straight line. From the graph we can see that when Amy does not buy any nachos then she can spend #30 to buy 12 beverages .

when Amy does not buy any beverages then she can spend #30 to buy 6 nachos.

Find the distance of PQ<br> P(0,4) and Q(10,-6)
solong [7]

Answer:

PQ ≈ 14.14 units

Step-by-step explanation:

calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = P (0, 4 ) and (x₂, y₂ ) = Q (10, - 6 )

PQ = \sqrt{(10-0)^2+(-6-4)^2}

     = \sqrt{10^2+(-10)^2}

     = \sqrt{100+100}

     = \sqrt{200}

     ≈ 14.14 units ( to 2 dec. places )
