Answer: k = 3

because p - 1 is a factor of the equation

=> at p = 1,  p^4 + p² + p - k =0

with p =1, we have: 1 + 1 + 1 - k = 0

⇔ k = 3

Step-by-step explanation:

Answer:

Solution,

since the factor of f(p) = p-1

we know, f(p)= 0

p=1 (from remainder theorem)

now,

f(p) =p^4+p^2+p-k

0= 1^4+1^2+1-k

0= 1+1+1-k

0= 3-k

k=3

[a+b]+(c)=(a)+[b+c]

Answer:

Step-by-step explanation:

H(t) =  -16[tex]t^{2}[/tex]+4.624  ( in feet)

0 = -16[tex]t^{2}[/tex] + 4,624

-4,624 =  -16[tex]t^{2}[/tex]

-4,624 / -16 = [tex]t^{2}[/tex]

289 = [tex]t^{2}[/tex]

17 = t

so.. 17 seconds to hit the ground..  :)

The piece of wood 17 seconds takes to hit the ground.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

A tornado drops a piece of wood from a height of 4,624 ft.

Given that the equation for the height as a function of time is

h(t) = -16t² + initial height

Substitute height = 4,624 ft. in the equation,

h(t) =  -16t² +4.624

At ground level, the value of h(t) is zero,

0 = -16t² + 4,624

16t² = 4,624

t² = 4,624/16

t² =289

t = 17

So, 17 seconds to hit the ground

Hence, the piece of wood 17 seconds takes to hit the ground.

Answer:

Costul unui kilogram de nectarine = x = 6 lei

Costul kilogram de piersicilor = y = 4 lei

Step-by-step explanation:

Lăsa

Costul nectarinelor = x

Costul piersicilor = y

Prin urmare:

Dacă 4 kg de nectarine și 6 kg de piersici costă 48 de lei

4x + 6y = 48 .... Ecuația 1

3 kg de nectarine și 9 kg de piersici costă 54 de lei

3x + 9y = 54 .... Ecuația 2

Combinând ambele ecuații

4x + 6y = 48 .... Ecuația 1

3x + 9y = 54 .... Ecuația 2

Rezolvăm folosind metoda Eliminare

Înmulțiți ecuația 1 cu 3 și ecuația 2 cu 4 pentru a elimina x

12x + 18y = 144 .... Ecuația 3

12x + 36y = 216 ... Ecuația 4

Scădeți ecuația 4 din 3

-18y = -72

y = -72 / -18

y = 4 lei

Pentru a rezolva pentru x: y = 4

4x + 6y = 48 .... Ecuația 1

4x + 6 × 4 = 48.

4x + 24 = 48

4x = 48 - 24.

4x = 24

x = 24/4

x = 6 lei

Prin urmare:

Costul unui kilogram de nectarine = x = 6 lei

Costul kilogram de piersicilor = y = 4 lei

Answer: 34.2 pounds

Step-by-step explanation:

First, convert 15 4/5 into an improper fraction. You should get 79/5. Then, convert 50 into a fraction that has a denominator of 5. Right now, 50= 50/1 so just multiply the top and bottom by 5 to make it 250/5. Then, subtract 79/5 from 250/5. You should get 171/5. Lastly, simplify. You should get 34.2 pounds as your final answer.

Answer: 3 3/4 inches

Step-by-step explanation:

From the question, we are informed that In April, it rained 1/4 of an inch on 15 different days.

The number of inches of rain that fell in April would be the multiplication of 1/4 by the total number of days. This would be:

= 1/4 × 15

= 15/4

= 3 3/4 inches

Answer:

The measures are 22 and 68 degrees

Step-by-step explanation:

for a right triangle, the total angle measure gives 90

Let one of the acute angle be x and the other be y

The measure of one of the acute angle is 4 times the the difference of the measure of the other angle and 5

x = 4(y-5)

Also x + y = 90

Put i into ii

4(y-5) + y = 90

4y-20 + y = 90

5y-20 = 90

5y = 90 + 20

5y = 110

y = 110/5

y = 22

But;

x = 4(y-5)

x = 4(22-5)

x = 4(17)

x = 68

The sum of the acute angles in a right-angled triangle is 90.

The acute angles are 22 and 68 degrees

Let the acute angles be x and y, such that:

[tex]\mathbf{y = 4(x - 5)}[/tex]

So, we have:

[tex]\mathbf{x + y = 90}[/tex]

Substitute 4(x - 5) for y

[tex]\mathbf{x + 4(x - 5) = 90}[/tex]

Open brackets

[tex]\mathbf{x + 4x - 20 = 90}[/tex]

Add x and 4x

[tex]\mathbf{5x - 20 = 90}[/tex]

Add 20 to both sides

[tex]\mathbf{5x = 110}[/tex]

Divide both sides by 5

[tex]\mathbf{x = 22}[/tex]

Recall that:

[tex]\mathbf{y = 4(x - 5)}[/tex]

So, we have:

[tex]\mathbf{y = 4(22 - 5)}[/tex]

[tex]\mathbf{y = 68}[/tex]

Hence, the acute angles are 22 and 68 degrees

When talking about the orthocenter, you want to make sure that the point you are looking for is in the exact center.  Since coordinate N of the x value is 1, we can safely assume that your top two choices are either a and b.  B wouldn't work since it is not at the exact center which makes your answer A.

Answer:

gjlll has 3

Step-by-step explanation:

amy has 555

Answer:

3

Step-by-step explanation:

Given that :

A1 = 2.5 ; Σdx1 = 50

A2 = 5.5 ; Σdx2 = -250

Mean (m) = A + Σdx/N = 50

m = A + Σdx/N

m - A = Σdx/N

Nm - NA = Σdx

From the parameters given :

Nm - 2.5N = 50 - - - (1)

Nm - 5.5N = - 250 - - - (2)

Subtract (1) from (2)

3N = 300

N = 300/3

N = 100

Put N = 100 in either (1) or (2)

From (2):

100(m) - 5.5(100) = - 250

100m - 550 = - 250

100m = - 250 + 550

100m = 300

m = 300/100

m = 3

Hence, Arithmetic mean = 3
