Answer:

B, Right by 4 units

Step-by-step explanation:

we want to factor g(x), and the factorization of that would be (x - 4)² as its a perfect square trinomial

when translating on a graph, we determine the translation. the translation of g(x) is a horizontal shift 4 units to the right, as we are subtracting 4. if it was adding 4, we would be shifting to the left 4 units

ANSWER

Right by 4 units

EXPLANATION

The given functions are

[tex]f(x) = {x}^{2} [/tex]

and

[tex]g(x) = {x}^{2} - 8x + 16[/tex]

To obtain how much f(x) is shifted to obtain g(x), we need to rewrite g(x) in vertex form.

Observe that,

[tex]g(x) = {x}^{2} - 8x + ( - 4) ^{2} [/tex]

is a perfect square trinomial.

The vertex form is

[tex]g(x) = {(x - 4)}^{2} [/tex]

When f(x) is shifted 4 units to the right, we obtain g(x).

Answer:

The Potato has a greater mass.

____________________________________________________

Step-by-step explanation:

In order to see which one of them has the greater mass, we're going to need to figure out how much one of them weigh.

Lets get the key information from the question:

5 potatoes = 1 kilograms (kg)

8 pears = 1,200 grams (g)

With the information above, we can solve the problem.

1 Kilogram = 1000 grams

With that information, we know that 5 potatoes would equal 1000 grams, now we would need to divide 1000 by 5 to get the grams for one potato in order to find the mass of it.

[tex]1000 \div 5=200[/tex]

1 Potato = 200 grams

Now, we would need to divide 1,200 by 8 to find the mass of 1 pear.

[tex]1200 \div 8=150[/tex]

1 Pear = 150 grams

With the information we have now, we would know that the Potato has the greater mass than the pear.

A potato has a greater mass.

Answer:

= 2.5 × 10-4

Step-by-step explanation:

That's all there is to know right???

Replace h with 49 ( the given height) and solve for d ( distance).

49 = d^2 - 36d +324

Subtract 49 from both sides:

0 = d^2 - 36d + 275

Factor the polynomial, by finding two numbers when added together equal -36 and when multiplied equal 275.

(d-25)(d-11) = 0

Now solve for d by setting both equations to 0:

d-25 = 0

d = 25

d-11 = 0

d = 11

The two distances would be 11 yards and 25 yards.

Answer:

32[tex]m^{2}/min[/tex]

Step-by-step explanation:

We let the length of the square be l, the diagonal be z and the area be A.

Then by Pythagoras theorem;

[tex]l^{2}+l^{2}=z^{2}\\2l^{2}=z^{2}[/tex]

The are of a square of length l is given as;

[tex]A=l^{2}[/tex]

Combining these two equations yields;

[tex]z^{2}=2A[/tex]

[tex]A=\frac{z^{2} }{2}[/tex]

Next, we have been given;

[tex]\frac{dz}{dt}=8[/tex]

We are required to find;

[tex]\frac{dA}{dt}[/tex] when z = 4

By chain rule;

[tex]\frac{dA}{dt}=\frac{dA}{dz}*\frac{dz}{dt}[/tex]

Differentiating [tex]A=\frac{z^{2} }{2}[/tex] with respect to z yields;

[tex]\frac{dA}{dz}=z[/tex]

Therefore,

[tex]\frac{dA}{dt}=\frac{dA}{dz}*\frac{dz}{dt}[/tex] = 8z

When z is 4m the area of the square will be increasing at a rate of;

8m/min * 4m = 32[tex]m^{2}/min[/tex]

The area of the square is increasing at a rate of 32 m^2/min when the diagonals are each 4 meters long. This is calculated using the relationship between the diagonal and the side length of the square, and applying the concepts of calculus.

The subject of your question is related to Mathematics, specifically in the field of calculus, which deals with rates of change and accumulation. In this scenario, we're looking at how fast the area of a square is increasing given that its diagonals are increasing at a steady rate.

In a square, the diagonal and the side length 's' have a specific relationship, given by the Pythagorean theorem as diagonal = s * sqrt(2). As the diagonal is increasing at 8 m/min, ds/dt = 8/(sqrt(2)) m/min. Now, the area of a square (A) is given by A = s^2. By differentiating this respect to time 't', dA/dt = 2s*(ds/dt). Substituting the given length of the diagonal (4 m), we find s = diagonal/sqrt(2) = 2 sqrt(2) m. Now, substituting s and ds/dt into the equation for dA/dt, we find dA/dt = 2s*(ds/dt) = 2*2sqrt(2)*8/sqrt(2) = 32 m^2/min. So, the area of the square is increasing at the rate of 32 m^2/min when the diagonals are 4 meters each.

Answer:

The minimum number of rolls she should buy is 9 rolls

Step-by-step explanation:

* Lets study the information in the problem

- Katie wants to put the crepe paper around the perimeter of the

 ceiling which shaped a square of side length 12 feet

- And also from each corner to the opposite corner

- She needs the length of the 4 sides of the square and the length

 of its 2 diagonals

* Lets find the length of the diagonal of the square

∵ The two adjacent sides of the square formed two legs of a right

   angle triangle and the diagonal joining the endpoints of the legs

  is the hypotenuse of the triangle

- Use Pythagoras theorem to find the length of the diagonal

∴ The length of the diagonal = √(s² + s²) √(2s²) = s√2

∵ The length of the side of the square = 12 feet

∴ The length of the diagonal = 12√2

* Now lets find the length of the crepe papers she needs

∵ She needs the length of the 4 sides of the square and the length

  of its 2 diagonals

∴ The length of crepe papers = 12 + 12 + 12 + 12 + 12√2 + 12√2 = 81.94 feet

∵ Each roll of the crepe papers contain 10 feet

- To find the number of rolls divide the length of the crepe papers by 10

∴ The number of rolls = 81.94 ÷ 10 = 8.194

* She must to buy 9 rolls to have enough crepe papers to decorate

 her ceiling

* V.I.N:

- If she decide to buy 8 rolls, some part of ceiling will not decorate

 because the 8 rolls have 80 feet only and she needs 81.94 feet

Answer:

The journey took 4 hours.

Step-by-step explanation:

The relationship between distance, speed, and time is expressed in the formula;

[tex]Speed=\frac{Distance}{Time}[/tex]

The car covered 52 km at a speed of 13km/h.

This means that; distance =52km and speed =13km/h

We substitute the given values into the formula to get;

[tex]13=\frac{52}{Time}[/tex]

[tex]Time=\frac{52}{13}[/tex]

This simplifies to:

[tex]Time=4hrs[/tex]

The journey took 4 hours.

The speed is the ratio of distance to time. Then the time taken by the journey is 4 hours.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distance}{Time}[/tex]

Then the time is given as

[tex]\rm Time = \dfrac{Distance}{Speed}[/tex]

A car drives 52 km at a speed of 13km/h.

Then the time taken will be given as

[tex]\rm Time = \dfrac{52}{13} \\\\ Time = 4[/tex]

1. 21x⁴+3y-35x² + 41

2. -21x⁴-3y+6x² + x

Step-by-step explanation:

When adding and subtracting polynomials , you can use the distributive property to add or subtract the coefficients of like terms.

1. The polynomial is 21x⁴ + 3y -6x² + 34

To obtain polynomial 29x² -7 , we must subtract some polynomial from it.

Let that polynomial be k.

So, 21x⁴ + 3y -6x² + 34 - k =  29x² -7

k = 21x⁴ + 3y - 6x² +34 - 29x² +7 = 21x⁴ + 3y - 35x² + 41

2. To obtain a first degree polynomial, let that polynomial be x +34

So, 21x⁴ + 3y - 6x² + 34 + K = x + 34

K = x + 34 - 21x⁴ -3y + 6x² - 34

  = -21x⁴ - 3y + 6x² + x
