Having trouble solving this

Answer:

If  p  is the smallest of  n  consecutive integers of the same sign than we have  p ,  p+1 ,  p+2 ,  … ,  p+(n−1) ,

So the sum is

∑k=0n−1(p+k)=∑k=0n−1p+∑k=0n−1k=np+n2−n2  

Here  n=4  

So we have  4p+6  

And checking

p+(p+1)+(p+2)+(p+3)=4p+6  

Note if  p=−v  

Than you have the same thing as if  p=v−n+1  just negative for example  3  consecutive integers the smallest is  −5  so the sum is  −5+(−4)+(−3)=3×−5+32−32=−15+3=−12  

On the other hand:

−(3+4+5)=−(3×3+32−32)=−(9+3)=−12  

If  p=−v  the sum of next  v+1  integers is  −(∑k=0vk)=−(v2+v2)  

Than needs an other  v  integers to bring it up to  0  again. From there it is

∑k=0hk=h2+h2  

Where  h=n−(2v+1) .

So recap if  p  is the smallest of  n  consecutive integers their sum is

p+(p+1)+(p+2)+…+(p+(n−1))=⎧⎩⎨⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪⎪np+n2+n2−(n|p|+n2+n2)((n−|p|)2+(n−|p|)2)−(|p|p+|p|2+|p|2)((n−|p|)2+(n−|p|)2)n≥0p<0∧n<|p|+1p<0∧|p|<n<2|p|+1p<0∧n>2|p|+1

Answer:

y- intercept = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Given

f(x) = [tex]\frac{1}{2}[/tex] [tex](6)^{x}[/tex]

To find the y- intercept let x = 0 , then

f(0) = [tex]\frac{1}{2}[/tex] [tex](6)^{0}[/tex] [ [tex]6^{0}[/tex] = 1 ]

      = [tex]\frac{1}{2}[/tex] × 1 = [tex]\frac{1}{2}[/tex] ← y- intercept

Answer:

41.83°

Step-by-step explanation:

It is given that :

The vertical distance of the UFO from the ground = 60,000 feet

The diagonal distance of the landing area to the UFO = 90,000 feet

In order to find the angle of depression, we have to use the trigonometric ratios, i.e.,

[tex]$\sin \ \theta = \frac{\text{perpendicular distance}}{\text{hypotenus}}$[/tex]

[tex]$\sin \ \theta = \frac{60,000}{90,000}$[/tex]

[tex]$\sin \ \theta = \frac{2}{3}$[/tex]

[tex]$\sin \ \theta = 0.667$[/tex]

∴ [tex]$\theta = \sin^{-1 }(0.667)$[/tex]

     = 41.83°

Answer:

The 3rd one

Step-by-step explanation:

Let find angle z

Using law of sines

[tex] \frac{xy}{ \sin(z) } = \frac{xz}{ \sin(y) } [/tex]

Plug in the numbers

[tex] \frac{43}{ \sin(x) } = \frac{40}{ \sin(68) } [/tex]

Flip both equations

[tex] \frac{ \sin(x) }{43} = \frac{ \sin(68) }{40} [/tex]

where z=85.4 or 94.6

Using the triangle interior sun theorem,

if z=85.4 let add up all so The first 2 are rules out angles to make sure they add up to 180.

[tex]if \: z = 85.4[/tex]

[tex]85.4 + 68 + x = 180[/tex]

[tex]x = 153.4[/tex]

[tex]x = 26.6[/tex]

The fourth one doesnt have 26.6 as a angle so it cant be that

Let try if z=94.6

[tex]68 + 94.6 + x = 180[/tex]

[tex]162.6 + x = 180[/tex]

[tex]x = 17.4[/tex]

The third one has that.

Also we reuse law of sines YZ=12.9 so it is the third one.

Answer:

16.5 in³

Step-by-step explanation:

Length(L) = 2.2 in

breadth (b) = 1.5 in

height (h) = 5 in

Volume of the cuboid

= L * b * h

= 2.2 * 1.5 * 5

= 16.5 in³

He made the mistake on step 1 because he didn't distribute

Answer:

Step 1

Step-by-step explanation:

2(5g - 1) = 3

1 Step: Distribute

2(5g - 1) = 3

10g-2=3

2 step: Add 2 to both side of the equation

10g -2=3

10g= -2+2=3+2

3 step: Simplify

4 step: Divide both sides of the equation by the same term

10g=5

10g/10 = 5/10

5 step: Simplify

g = 1/2

Answer: 4/12

Answer:

1. vertical translation (the point goes straight up)

2. P'(0,7) (the translation was up five units and over 1 unit)

3. f(-2)=2(-2)^2-4= (all y values are 4) (0,4)

f(0)=2(0)^2-4= (all y values are -4) (0,-4)

f(1)=2(1)^2-4= (all y values are -2) (0,-2)

Answer:

La regla de los signos son los positivos y los negativos.Pero otra cosa son cuales son las raglas de los signos.

Step-by-step explanation:

p = perimeter

w = width

let the length be l

as we know that

perimeter of rectangle (p).= 2(l+ w)

p = 2 ( 5+w)

p = 10 + 2w

so here variable p is dependent on the value of w.

Answer:

4

Step-by-step explanation:

Total number of television sets = 26

With the condition given that; every 2nd set had blue mark on it, and every 3rd set had green mark on it.

The number of only blue marked set is 8, while the number of only green marked set is 4.

So that, the number of television sets with both blue and green mark on them is 4.

Answer:

total number of marble=8

p(of green marble)=2/8=1/4

p(of yellow marble)=2/8=1/4

p(of red marble)=2/8=1/4

p(of purple marble)=1/8

p(of blue marble)=1/8.

Answer:

  $14

Step-by-step explanation:

Computing 40% can be done a couple of ways.

  40% = 40/100 = 4/10 = 2/5

  40% of 35 = (2/5)(35) = 2(35/5) = 2(7) = 14

__

  40% = 4/10 = 2(2(1/10))

  40% of 36 = 2(2(1/10)(35)) = 2(2(3.5)) = 2(7) = 14

The amount discounted is $14.

Answer:

9 metros

Step-by-step explanation:

Da pergunta acima

Fator de escala =

Medida correspondente: Representação do objeto

= 1: 200cm

Conseqüentemente:

1 cm = 200 cm

4,5 cm = x cm

x cm = 4,5 × 200 cm

x cm = 900 cm

O comprimento real deste lado do triângulo (hipotenusa) = 900cm

Pediram-nos para converter para metros

100cm = 1 m

900cm = xm

Multiplicação cruzada

100 cm × xm = 900 cm × 1 m

xm = 900 cm × 1 m / 100cm

xm = 9m

O comprimento real deste lado do triângulo (hipotenusa) em metros = 9 metros
