find the length of the gray arc in terms of pi

The range of the following function is

We can also call the range of a function an image, the range or image of a function is a set, we can see this set looking at the graph and see which values of y the function have, remember that we can have the same y value for different x value, looking at our graph we can see that this function comes from high y values, have a vertex on (3,1), in other words, it stops at y = 1 and then start growing again, and go on repeated values of y, then we can say that the image (values of y that the function assumes) is all values bigger than 1, therefore {y > 1}.

Answer:

4.5 pounds

Step-by-step explanation:

21.5 - 3.5 = 18

We divide that by 4 (Aug., Sept, Oct. Nov.)

18/4 = 4.5

Answer:

6.144

Step-by-step explanation:

I) 2y = x - 4

II) 4x + 3y = 5

First, we put all the variables on the same side subtracting x from both sides of equation I:

I) 2y - x = -4

II) 3y + 4x = 5

Now, we multiply equation I by 4:

I) 8y - 4x = -16

II) 3y + 4x = 5

Then, we add equation I to equation II:

I) 8y - 4x = -16

II) 11y = -11

Therefore, we got from equation II:

y = -11/11 = -1

Applying this result on equation I, we got:

-8 - 4x = -16

4x = 8

x = 8/4 = 2

Final answer: (x,y) = (2,-1)

Question: the line that passes through the point (-1,4) and point (6,y) has a slope of 5/7. find y.

Solution:

By definition, the slope of a line is given by the formula:

where m is the slope of the line and (X1,Y1), (X2,Y2) are any two points on the line. In this case, we have that:

(X1,Y1) = (-1,4)

(X2,Y2) = (6,y)

m = 5/7

thus, replacing the above data into the slope equation, we get:

this is equivalent to:

By cross-multiplication, this is equivalent to:

Answer:

slope = 5/3

y-intercept = -4

Step-by-step explanation:

First, move the x to the other side of the equation:
-3y=-5x+12
Then, divide BOTH sides by -3, so that there is no coefficient next to y:
y=5/3x-4

Then, just look at the constant and coefficient next to x (m). The slope is 5/3 and the y-intercept is -4.

Hope this helps!

Answer:

[tex]y = \frac{5}{3}x - 4[/tex]

Step-by-step explanation:

move the 5x to a -5x

-3y= -5x+12

-3/-3= -5x÷ -3 12÷ -3

y = 2 (option D)

y = -x + 12

4x - 2y = 36

rewriting the equations:

y + x = 12 ....equation 1

-2y + 4x = 36 ....equation 2

Using elimination method:

we will be eliminating y. So we need to make the coefficient of y to be the same in both equation. We will be multiplying the first equation by 2.

2y + 2x = 24 ....equation 1

-2y + 4x = 36 ....equation 2

Add both equations:

2y + (-2y) + 2x + 4x = 24 + 36

2y-2y + 6x = 60

6x = 60

x = 60/6 = 10

Insert the value of x in any of the equation. Using equation 2:

4(10) - 2y = 36

40 -2y = 36

-2y = 36 - 40

-2y = -4

y = -4/-2

y = 2 (option D)

When the price of bananas goes from $0.39 per pound to $1.06 per pound, the likely effect of quantity demanded is that it will reduce.

The quantity of a commodity or service that consumers are willing and able to acquire at a particular price within a specific time period is referred to as demand. The quantity required is the amount of an item or service that customers will purchase at a certain price and period.

Quantity desired in economics refers to the total amount of an item or service that consumers demand over a given time period. It is decided by the market price of an item or service, regardless of whether or not the market is in equilibrium.

A price increase nearly invariably leads to an increase in the quantity supplied of that commodity or service, whereas a price decrease leads to a decrease in the quantity supplied. When the price of good rises, so does the quantity requested for that good. When the price of a thing declines, the demand for that good rises.

Answer:

• Slope perpendicular to the line: 8/5

• Slope parallel to the line: –5/8

Explanation

Given

To know the result, it is better if we work with the slope-intercept form:

Then, to get this kind of form we have to isolate y from the given equation:

Thus, in this case, m = –5/8 and b = 7/8.

Perpendicular lines have negative reciprocal lines:

where m₁ is the slope of line 1 and m₂ is the line perpendicular to line 1.

Then, replacing the values:

Finally, the slopes of parallel lines are the same, meaning:

where m₁ is the slope of line 1 and m₂ is the line parallel to line 1.

We have the following: system of equations:

A: 3c=d-8

B: c=4d+8

To eliminate variable d first, if we want to use elimination method, we need to have variable d in both equations with the same coefficient but with different signs.

As in equation B, the coefficient of d is 4, then we need to have in equation A a coefficient of -4 for variable d.

Then the answer is we need to multiply equation A by -4.

Explanation

Given:

A bug is moving along a straight path with velocity

What to find:

The total distance traveled by the bug over interval [0, 6].

Solution:

To find the total distance traveled by the bug over interval [0, 6], you first integrate v(t)= t² - 6t + 8

2) y = 8x² +2x -15

(4x -5)(2x +3)

S={-3/2, 5/4}

3) y= 4x² +20x +24

(4x +8)(x +3)

S={-2,3}

1) Factoring these quadratic functions we have:

2) y = 8x² +2x -15

Let's call u, and v two factors.

Multiplying 8 by -15 = we have u*v = -120 Adding u + v= 2, so u = 12 and v =-10

12 x -10 = -120

12 +(-10) = 2

So, now we can rewrite it following this formula:

(ax² + ux) +(vx +c)

(8x² +12x) +(-10x-15) Rewriting each binomial in a factored form

4x(2x +3) -5(2x+3)

(4x -5)(2x +3)

Equating each factor to zero to find out the roots:

(4x -5) =0

4x =5

x=5/4

(2x +3) = 0

2x = -3

x= -3/2

Hence, the solution set is S={-3/2, 5/4}

3) y= 4x² +20x +24

Proceeding similarly we have:

u * v = 96

u + v = 20

So u = 12, and v =8 12x 8 = 96 12 +8= 20

Rewriting into (ax²+ux)+(vx +c)

(4x²+12x) +(8x+24) Factoring out each binomial

4x(x+3) +8(x+3) As we have a repetition we can write:

(4x +8)(x +3)

3.2) Now to find out the roots equate each factor to zero, and solve it for x:

4x +8 = 0

4x = -8

x =-2

x+3 =0

x=-3

4) Hence, the answers are:

2) y = 8x² +2x -15

(4x -5)(2x +3)

S={-3/2, 5/4}

3) y= 4x² +20x +24

(4x +8)(x +3)

S={-2,3}
