If you multiply a number by 0, you get 0, right?

So, all you have to do is make one paretheses equal to 0.

First case:

w=-1/5

(-1+1)(5+1/5)= 0(5+1/5)=0

Second case:

w=5

(25+1)(0)=0

Answer:

Quadrilateral

Step-by-step explanation:

In the sandbox, opposite sides are equal.

However, using Pythagoras Theorem

[tex]14^2\neq 12^2+8^2\\196 \neq 208[/tex]

Therefore, the sandbox cannot be a rectangle since if it were, each triangle must be a right triangle.

In the triangle

Since [tex]198<208[/tex], Angles C and X are acute angles.

Therefore, the sandbox does not satisfy the properties of any known quadrilateral. It is simply a quadrilateral-shaped sandbox.

Answer:

a. 16.41%

b. 68.57%

Step-by-step explanation:

We have that the poisson formula is as follows:

P (x = x) = (e ^ l) * (l ^ x) / x!

In this case l = 5.3

a. 4 exactly therefore x = 4, replacing:

P (x = 4) = (e ^ 5.3) * (5.3 ^ 4) / 4!

P (x = 4) = 0.1641

That is, the probability is 16.41%

b. between 2 and 6 complaints.

P (2 <= x <= 6) = P (x = 2) + P (x = 3) + P (x = 4) + P (x = 5) + P (x = 6)

replacing:

P (2 <= x <= 6) = (e ^ 5.3) * (5.3 ^ 2) / 2! + (e ^ 5.3) * (5.3 ^ 3) / 3! + (e ^ 5.3) * (5.3 ^ 4) / 4! + (e ^ 5.3) * (5.3 ^ 5) / 5! + (e ^ 5.3) * (5.3 ^ 6) / 6!

P (2 <= x <= 6) = 0.6857

In other words, the probability is 68.57%

Answer:he slope-intercept form of the equation of a line that passes through point (–3, 8) is y = –x + 6. What is the point-slope form…

Step-by-step explanation:

Answer:

-14/15 - 1/3v

Step-by-step explanation:

-6/5 -2/3v + 4/15 + 1/3v

= -6/5 + 4/15 - 1/3v

————————————

to allow -6/5 to be added to 4/15, you have to make the denominators the same by multiplying -6/5 by 3/3

————————————
-6/5(3/3) = -18/15

-18/15 + 4/15 - 1/3v

= -14/15 - 1/3v

Answer: 27

Step-by-step explanation:

The perimeter is the lengths of all sides of the figure added together. Since all  sides are equal in this triangle, we know all sides have a length of 9. We know this because all sides have 2 little lines on them, symbolizing that they are equal.

P=9+9+9=27

Answer:

x + 2y = -1

Step-by-step explanation:

First, we'll find the slope.

Slope = (2 - (-3)) / (-5 - 5) = 5 / -10 = -1/2

Since we know the slope and a point that belongs to the line, we can write this in point-slope form which will be:

y - 2 = -1/2(x - (-5))      *I used (-5, 2) but it doesn't matter which point you use

y = -1/2(x + 5) + 2

y = -1/2x - 1/2

Standard form:

1/2x + y = -1/2

x + 2y = -1

Answer: 21pi / 5

Step-by-step explanation:

Given the following :

Theta (θ) = 3π / 5

radius (r) = 7cm

The length of an arc is calculated using the formula:

(θ / 360) × 2πr

Inputting the provided values into our formula;

θ = 3π/5 = (3 × 180)° / 5 = 540°/5 = 108°

Length = (108 / 360)° × 2π × 7

Length = (3/10) × 14π

Length = 42π / 10

Length = 21π / 5 cm

Yes, this is a function. This is a function because there are no repeating x values. This can be seen using the vertical line test.

Prove

To start with; we open the bracket on the left hand side

[tex](sin x - cos x)^2 = (sin x - cos x)(sin x - cos x)[/tex]

[tex](sin x - cos x)^2 = (sin x )(sin x - cos x)- (cos x)(sin x - cos x)[/tex]

[tex](sin x - cos x)^2 = sin^2 x -sinx cos x - sin xcos x + cos^2 x[/tex]

[tex](sin x - cos x)^2 = sin^2 x -2sinx cos x + cos^2 x[/tex]

Reorder

[tex](sin x - cos x)^2 = sin^2 x + cos^2 x - 2sinx cos x[/tex]

From trigonometry;

[tex]sin^2x + cos^2x = 1[/tex]

So;

[tex](sin x - cos x)^2 = sin^2 x + cos^2 x - 2sinx cos x[/tex]

becomes

[tex](sin x - cos x)^2 = 1 - 2sinx cos x[/tex]

Also from trigonometry;

[tex]sec^2x - tan^2x = 1[/tex]

So,  

[tex](sin x - cos x)^2 = 1 - 2sinx cos x[/tex]

Answer:

Revenue =  5( 1000 + w+ k)

Step-by-step explanation:

Lets calculate expenses first

rent = $1000

wages = w

overhead cost = k

Total cost = rent + wage+ overhead

Total cost = 1000 + w+ k

Given Jose wants his monthly sales revenue, x, to be 4 times greater than the operating costs

Let revenue be R

Thus, putting the statement mathematically

revenue - total cost = 4 * operating cost

R - ( 1000 + w+ k) = 4( 1000 + w+ k)

R =  4( 1000 + w+ k) + ( 1000 + w+ k)

R =  5( 1000 + w+ k)

Thus, revenue should be  5( 1000 + w+ k).

Step-by-step explanation:

x+y=48

x=y-6

substitute "y-6" instead of x

x+y=48

(y+6)+y=48

y+y is equal to y

6+y=48

-6     -6

y= 42

x= 48-y

x=48-42

x=6

I hope this helped

Answer:

Step-by-step explanation:

x  - the small number

x+6  - the big number

x + x + 6 = 48

2x + 6 = 48

Verifying:

x+6 = 21 + 6 = 27

21 + 27 = 48

Answer:

[tex]a^4 -2a^2 -24[/tex]

Step-by-step explanation:

Given

[tex](a^2- 6) \ and\ (a^2+ 4)[/tex]

Required

Find the trinomial

Let T represents the trinomial;

To calculate the trinomial, we simply multiply the above factors;

This done as follows;

[tex]T = (a^2 - 6)(a^2 +4)[/tex]

Expand

[tex]T = a^2(a^2 +4) -6(a^2 +4)[/tex]

Open bracket

[tex]T = a^2*a^2 +a^2*4 -6*a^2 -6 * 4[/tex]

[tex]T = a^4 +4a^2 -6a^2 -24[/tex]

[tex]T = a^4 -2a^2 -24[/tex]

The above can not be solved any further; hence, the trinomial is [tex]a^4 -2a^2 -24[/tex]

Answer:

square - 3m on each side

triangle- 4m on each side

Step-by-step explanation:

4*l=3(l+1)

4l  = 3l+3

-3l       -3l

l= 3m

Answer:

square: 3 m on each side

triangle: 4 m on each side

Step-by-step explanation:

Suppose the length of the square is called x meter.

Then the perimeter of that square garden is 2 times the length and 2 times the width = 2x + 2x = 4x

So perimeter square garden = 4*(x)

Given

1. The length of the side of the equilateral triangle = x+1

Then the perimeter of the equilateral triangle is 3 times x+1 = 3*(x + 1) = 3x + 3

So perimeter equilateral triangle garden = 3*(x) + 3

Given

2. Both gardens have the same perimeter.

perimeter square garden = 4x

perimeter equilateral triangle garden = 3x + 3

Combine these two pieces of information:

4x = 3x + 3

4x -3x = 3

x = 3

Since the length of the square was called x meter, we now know that one side of the square must be 3m.

square: 3 m on each side.

Since length of the side of the triangle = x+1, we now know that one side of the triangle garden = 3 +1 = 4m.

triangle: 4 m on each side.

Answer:

3 (x - 5.50) = 111.75

Step-by-step explanation:

They paid $111.75 for three months,  that means they minus $5.50 every month which means a total of $16.5 for three months.

So you need use $111.75 plus the credit $16.5 for three months

111.75 + 16.5 = 128.25

Then use divide them by 3, (three months)

128.25 / 3 = 42.75

So they pay $42.75 per month before the credit.

Answer:

n(n +1) is the Total number of seats in the corner section.

Step-by-step explanation:

We are given that:

Number of seats in first row = 2

Number of seats in second row = 4

Number of seats in third row = 6

:

Number of seats in [tex]n^{th}[/tex] row = [tex]2n[/tex]

We can clearly see that it is an Arithmetic progression with

First term, a = 2

Common Difference, d = 2

[tex]n^{th}[/tex] term, [tex]a_n=2n[/tex]

To find: Total number of seats in corner sections with n rows.

i.e. Sum of n terms of above AP.

Formula for sum of n terms of an AP:

[tex]S_n=\dfrac{n}{2}(2a+(n-1)d)\\[/tex]

Putting the values:

[tex]\Rightarrow \dfrac{n}{2} ({2 \times 2 +(n-1)2})\\\Rightarrow \dfrac{n}{2} (4 +2n-2)\\\Rightarrow \dfrac{n}{2} (2n +2)\\\Rightarrow \dfrac{n}{2} \times 2(n +1)\\\Rightarrow n(n +1)[/tex]

n(n +1) is the Total number of seats in the corner section.
