Which function is equivalent tof(x)=4x2+12x+9?

Question 6 options:

(4x+3)(x+3)

(2x+3)2

(2x−3)2

(4x−3)(x−3)

Answer:

  y = 150x^2 -60x +6

Step-by-step explanation:

Do what the problem statement tells you: substitute for u.

  y = 6u^2

  y = 6(5x -1)^2 . . . . . . . . . . substitute 5x-1 for u

  y = 6(25x^2 -10x +1) . . . . expand the square

  y = 150x^2 -60x +6 . . . use the distributive property

The three ratios of 24 and 8 are 12:4, 6:2 and 3:1.

A ratio indicates how many times one number contains another.

The ratios of 24 apples and 8 bananas is written as follows;

12 apples : 4 bananas

6 apples : 2 bananas

3 apples : 1 banana

Thus, the three ratios of 24 and 8 are 12:4, 6:2 and 3:1.

Step-by-step explanation:

============================================

Explanation:

x = number of years

y = number of grills sold

The equation we'll use is the exponential equation [tex]y = 3300(1.06)^x[/tex]

The 3300 of course is the initial amount sold. The 1.06 as the base indicates that the sales increase by 6% each year. Think of it the 1.06 as 1+0.06 = 100% + 6%

If we plugged x = 0 into that equation, then we get

[tex]y = 3300(1.06)^x = 3300(1.06)^0 = 3300[/tex]

which helps confirm the correct equation.

----------------

Now plug in x = 6 to find the sales for year 6.

[tex]y = 3300(1.06)^x = 3300(1.06)^6 \approx 4681.11 \approx 4681[/tex]

The projected sales for year 6 are about 4681 grills. This is an estimate based on the assumption that the sales will increase by 6% each year. Of course, the reality is that things aren't always so simple like this (but it should give a fairly good idea of what's going on).

Answer:

30, 80

Step-by-step explanation:

Let the smaller number be [tex]x[/tex]. Then, the other number is [tex]2x+20[/tex]. The sum is 110, so

[tex]x+(2x+20)=110.[/tex]

Simplifying gives

[tex]3x+20=110[/tex].

Subtracting 20 from both sides gives

[tex]3x=90[/tex].

Dividing by 3 gives

[tex]x=30[/tex].

The smaller number is 30 and the larger number is 2(30)+20=80.

Answer:

See, that doesn't make sense.

First of all, 4 is the only number equal to 4. Sp, it'd be 9+4 = 13

Then I'm assuming you're also subtracting 4 from 13, so the answer would be 9.

Hope this helped, have a nice day.

Answer:

The side length for A and B is 30 and the side length for B and D is 16, in the new dilated rectangle. The reason we multiplied by 2 is because 2 is greater than 1, and this means the image is an enlargement.

Step-by-step explanation:

Dilation is where the polygon grows or shrinks but keeps the same overall shape. A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement (think stretch) is a dilation that creates a larger image. If the scale factor is between 0 and 1 the image is a reduction. If the scale factor is greater than 1, the image is an enlargement. This means that the image, A’, is twice as large as the pre-image A. This means that the image, A’, is twice as large as the pre-image A.

Since 2 is greater than 1, the image is an enlargement

So we do 2*15 and 2 * 8

And we get

30 and 16

The side length for A and B is 30 and the side length for B and D is 16.

Answer:

Step-by-step explanation:

To divide by a fraction, multiply by the reciprocal of that fraction

[tex]\frac{10}{3}[/tex] ÷ [tex]\frac{6}{5}[/tex]

Reduce the numbers with the greatest common factor which is 2

[tex]\frac{10}{3}[/tex] ×[tex]\frac{5}{6}[/tex]

multiply the fractions

[tex]\frac{5}{3}[/tex] × [tex]\frac{5}{3}[/tex]

Answer:

AB and CD would be 30

AC and BD would be 16

Step-by-step explanation:

The scale factor is what you multiply the sides by. Dilate means wider or larger so you multiply each side by the scale factor of 2 to get the higher scaled rectangle.

The side lengths on the new dilated rectangle will be 30cm and 16cm

Given the following parameters

If the length and breadth are dilated by a factor of 2, hence the new dimansion will be:

New length = 2(15) =30cm

New width =2(8) = 16cm

Hence the side lengths on the new dilated rectangle will be 30cm and 16cm

Answer:

The coordinates of the image of the point (6,6) under the same  translation is: (9, 2)

Hence, option C is correct.

Step-by-step explanation:

The image of the point (2, 1) under a translation is (5, -3).

It means when we horizontally move 3 units to the RIGHT i.e. adding 3 units to the x-coordinate and vertically move 4 units DOWN i.e. subtracting 4 units from the y-coordinate of the original point (2, 1), we get the coordinates of the image (5, -3).

Thus,

The rule of translation can be formulated such as:

(x, y) → (x + 3, y - 4)

(2, 1) → (2 + 3, 1 - 4) → (5, -3)

Thus,

Under the same rule of translation, we can determine the coordinates of the image of the point (6,6):

(x, y) → (x + 3, y - 4)

(6, 6) → (6 + 3, 6 - 4) → (9, 2)

Therefore, the coordinates of the image of the point (6,6) under the same  translation is: (9, 2)

Hence, option C is correct.

The equation that allows determining the probability that the player wins the prize after n games is [tex]0.35^n[/tex] = Probability. The player should choose n = 10.

The simple definition of probability is the likelihood that an individual event will occur. It can be discussed the probabilities of distant outcomes, or how probable they are, whenever we're skeptical of how an occurrence will turn out. Statistics refers to the study of events subject to probability.

First, solve the following equation to find the likelihood of the player winning the prize after n games given that the probability of winning a specific game is 0.5 and that the player wins a prize if at least 70[tex]\%[/tex] of the games in a series are won.

[tex]Probability = 0.5^n \times 0.70[/tex]

[tex]Probability = 0.35^n[/tex]

It is evident here that the larger the value of n, the lesser the chances to win.

For example, if there were five games played, the equation would be as follows:

[tex]0.35^5 = 0.005[/tex]

So. the value of n chosen by the player should be 10.

The complete question is as follows:

The probability of winning a certain game is 0.5. If at least 70 percent of the games in a series of n games are won, the player wins a prize. If the possible choices for n are n = 10, n = 20, and n = 100.

Which value of n should the player choose in order to maximize the probability of winning a prize?
