Sketch the curve with the given vector equation. Indicate with an arrow the direction in which t increases.

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.

Answer:

265

Step-by-step explanation:

1590/6=265

265x1=265

To each side, add 4 positive unit tiles.

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.

Allison feeds 11 horses in a day.

Horses are herbivores and, as such, they need a very specific diet. They must consume lots of fiber to keep their extremely long and sensitive digestive tract working and they must eat little and often, almost all day long.

A horse's feed should consist primarily of grass or roughage. However, hay is insufficient to provide a complete nutritional profile. Important minerals and nutrients will be added by adding grains and concentrates, but calories will also be added. Roughage, feeds, and concentration types are listed below, from least to most "complete."

Allison feeds 2 quarter horses and 3 paint horses the same amount each day.

Therefore, she feeds 2*4+3 = 11 horses in a day.

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.

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

The compound inequality solved are:

x ≤ 2 and x > -5

x > 4 or x < -5.3

The graph of the number line is given above.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

-2 x ≤ 4 and 10 > -2x

x ≤ 4/-2 and 10/2 > -x

x ≤ -2 and 5 > -x

x ≤ 2 and x > -5

This means.

-5 < x ≤ 2

The number line can be graphed as,

10 < 3x - 2 or -3x - 2 > 14

12 < 3x or -3x > 16

x > 4 or -x > 16/3

x > 4 or x < -16/3

x > 4 or x < -5.3

x > 4 can be represented on a line graph as,

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

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).

Answer: y-3 = -4/5(x+0)

Step-by-step explanation:

formula

y-y1=m(x-x1)

y = y coordinate of the second point

y1 = y coordinate of point one

m = slope

x = x coordinate of the second point

x1 = x coordinate of point one

slope formula

y2-y1/x2-x1

-1-3/5-0

slope = -4/5

the 2 points on the graph are (0,3) (5,-1)

substitute and solve

y-3 = -4/5(x+0)

y-3=-4/5x

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
