The total years taken to double the money according to Compounding will be 12.5  years.

What is compound interest?

Compound interest is that the interest on savings calculated on each the initial principal and therefore the accumulated interest from previous periods.

Main body:

Given :

rate = 6%

amount = $900

Total amount = $1800

Compounded monthly,

so formula becomes,

Total amount = amount (1+r/1200)^12t

T = A[tex](1+r/1200)^{12t}[/tex]

1800 = 900 (1+6/1200)^12t

2 = (1+1/200)^12t

2 = 1.005^12t

taking log on both sides

log 2 = 12t *log 1.005

0.3/0.002 = 12t

t = 12.5 years

Hence the time taken to double the money is 12.5 years.

"Define variables"

→ The number of student's tickets = a

→ The number of non-student tickets = b

→ the total cost represented = y

"Create an equation that models this situation"

→ y = $5 × a + $10 × b

"Rewrite the equation in slope intercept form"

→ y = $5 × a + $10 × b

→ y = 5a + 10b

→ 250 = 5a + 10b

Using translation concepts, the equation for the graph is b.

y = cos(x + π/2) + 1

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

Suppose that we've got:

f(x) = a cos (bx - c) + d

Then, this function has:

Amplitude (the maximum distance of the graph from the middle line) = a

Period =[tex]\dfrac{2\pi}{b}[/tex]

Phase shift = [tex]\dfrac{c}{b}[/tex]

Maximum value: a + d

Minimum value: -a + d

In this problem, we have a cosine function

(zero at π/2, this is zero at the origin), shifted π/2 units to the right and 1 unit up.

Since the standard amplitude is between -1 and 1, here is between 0 and 2).

Hence the rule is given as follows:

b. y = cos(x + π/2) + 1

The answers are ; a) -5/9, 6/10, -7/11, 8/12, b) f(n) = n/(n+4) and c) f(56) is positive.

A sequence is defined as an arrangement of numbers in a particular order.

A sequence is given ; -1/5, 2/6, -3/7, 4/8.....

Part A

From inspection of the sequence, the pattern is:

i) Add 1 to the numerator of the previous term.

ii) Add 1 to the denominator of the previous term.

iii) Make every other term negative.

Therefore, The next four terms are -5/9, 6/10, -7/11, 8/12

Part B

From inspection of the sequence, we can see that the numerator is the position of the term (n) in the sequence.  So when n = 1 the numerator is 1, when n = 2 the numerator is 2, etc.

The denominator is 5 more than the position of the term in the sequence.  So when n = 2 the denominator is 2 + 4 = 6, and when n = 4 the denominator is 4 + 4= 8.

Hence, the rule can be,

f(n) = n/(n+4)

If n is even, then f(n) is positive.

If n is odd, then f(n) is negative.

Part C

56 is an even number.

As the function f(n) is positive when n is even, the sign of f(56) is positive.

Therefore, the answers are ; a) -5/9, 6/10, -7/11, 8/12, b) f(n) = n/(n+4) and c) f(56) is positive.

Step-by-step explanation:

w = -8 -5 =-13=13

Answer:

y = 2x - 5

Step-by-step explanation:

slope = 1-(-3)/3-1

4/2 = 2

this is the m value, or value before x.

So far, this is what we have: y = 2x + b

To find b, we plug in one of the points we have, into the equation.

(in this case ill use (3, 1), where 3 is the x and 1 is the y)

So,

1 = 2(3) + b

1 = 6 + b

1 - 6 = b

-5 = b

Finally,

y = 2x - 5

Required equation of the parabola with origin as its vertex and directrix  

y = 1/2 is equal to x² = -2y.

As given in the question,

Let vertex of the parabola be ( h, k )

Vertex of the given parabola be at origin

⇒ ( h , k ) = ( 0 , 0 )

Directrix is y =1/2 above the vertex.

Focus is ( 0, -1/2)

Equation of the parabola is given by

Distance between focus to the vertex = distance between vertex to the directrix

( y - (1/2) )² = ( x - 0)² +  ( y - (-1/2) )²

⇒ y² - y + 1/4 = x² + y² + y + 1/4

⇒ -y = x² + y

⇒x² = -y - y

⇒ x² = -2y

Therefore, the equation of the parabola with vertex at origin and directrix y =1/2 is equal to x² = -2y .

Answer:

  8.2 m

Step-by-step explanation:

You want the length of the shadow whose tip is 34 m from the top of a 33 m building.

The described geometry can be modeled by a right triangle with one leg 33 m and hypotenuse 34 m. The Pythagorean theorem tells us the length of the other leg is ...

  a² +b² = c²

  b² = c² -a²

  b = √(c² -a²)

  b = √(34² -33²) ≈ 8.2 . . . . meters

The length of the shadow is about 8.2 meters.

__

Additional comment

The angle of elevation to the top of the building can be found from the trig relation ...

  Sin = Opposite/Hypotenuse

And the length of the shadow can be found from the relation ...

  Cos = Adjacent/Hypotenuse

If α is the angle of elevation, then ...

   sin(α) = 33/34   ⇒   α = arcsin(33/34)

and

  Adjacent = Hypotenuse × cos(α)

  Adjacent = 34·cos(arcsin(33/34)) ≈ 8.2 . . . . meters

where the "adjacent" side of the triangle is the side between the building and the tip of the shadow, along the ground.

The 16th term of the arithmetic sequence value is 103.

The 16th term of the arithmetic sequence whose common difference is d=7 and whose first term is a↓1=-2

An arithmetic sequence is defined as an=a1+d (n-1). In essence, this indicates that the term you're looking for, an, is equal to the first term, a1, plus the term difference, d, times the number of terms, n, minus one. For this issue, that essentially means that

an=a1+d(n-1)

The value of an at term sixteen is equal to -2 + 7*. (16-1)

PEDMAS is used to

a16= -2+7*15

a16= -2+105

a16= 103

Therefore, 103 will be the 16th term's value.

What is a one-variable linear equation and what does it look like?

The equation for a linear equation in one variable is written as ax+b = 0, where a and b are two integers, and x is a variable. This equation has only one solution. For instance, the linear equation 2x+3=8 only has one variable.

The initial formula is:

3x - 4 = 2x + 5

Four positive unit tiles are added to each side, giving us:

3x - 4 + 4 = 2x + 5 + 4

3x = 2x + 9

which removes the independent elements off both sides of the equal sign and places them all on the right side (the +9 term), simplifying the initial equation. You'll see that the other choices don't produce this outcome.
