Find the product.
(x + 9)(4x2 + 5x + 6)

Answer:

27

Step-by-step explanation:

Plug in 12 every time you see "x". When you do this it should be f(12) = 3(12) - 9 = 36 - 9 = 27.

Hope this helped :)

The function value f(12) for f(x) = 3x - 9 is calculated by substituting x with 12, resulting in f(12) = 3(12) - 9, which simplifies to f(12) = 27.

To find the value of f(12) for the given function f(x) = 3x - 9, you simply substitute the value of 12 for x and then perform the calculation:

f(12) = 3(12) - 9
f(12) = 36 - 9
f(12) = 27

Therefore, the function value of f(12) is 27. When plotting or using a graph, this is the y-coordinate when x is 12 for the equation y = 9 + 3x, which has a slope ('m') of 3 and a y-intercept ('b') of 9.

Answer:

[tex]\frac{7}{20}x < 26.25[/tex]

Step-by-step explanation:

If $x is the value of the gift card when Tyler entered the store, then after spending [tex]\frac{13}{20}[/tex] of the gift card the card's value was less than $26.25.

So, we can write the inequality as

[tex]x - \frac{13}{20}x < 26.25[/tex]

⇒ [tex]\frac{7}{20}x < 26.25[/tex]

So, this is the required inequality that describes x, the value of the gift card when Tyler entered the store. (Answer)

The solution to the quadratic equation is x = -4

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

2x² + 8x = x² - 16

Subtracting x² on both sides , we get

x² + 8x = -16

Adding 16 on both sides , we get

x² + 8x + 16 = 0

On simplifying the equation , we get

( x + 4 )² = 0

Taking square roots on both sides , we get

x + 4 = 0

Subtracting 4 on both sides , we get

x = -4

Therefore , the value of x is -4

Hence , the solution is x = -4

(Before continuing reading, I took the base to be 3. Please tell me if you didn't want the base to be 3.)

Step-by-step explanation:

I assume 3 is suppose to be the base. Let's list some values that can be written as 3 to some integer.

3^0=1

3^1=3

3^2=9

3^3=27

3^4=81

3^5=243

......

I could have also did negative integer powers, but this is all I really need to convince you that log_3(28) is between 3 and 4.

log_3(28) means the value x such that 3^x=28.

Since 28 is between 27 and 81 in my list above, that means 3^x is between 3^3 and 3^4. This means that x is a value between 3 and 4.

Answer for the first blank = infinity

Answer for the second blank = 9000

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

Explanation:

Note how the graph goes on forever in both left and right directions. So x extends forever in both directions. This means any x can be an input to the function. The domain is -infinity < x < infinity. Basically, the domain is the set of all real numbers.

The range is -infinity < y <= 9000 since there is no smallest y value, but the largest y can be is y = 9000. Look at the highest point of the parabola and note the y coordinate of this point. This highest point is called the vertex.

Answer:

6

Step-by-step explanation:

6 multiplied by 6 is 36.

Answer:

6

Step-by-step explanation:

When you are solving for a certain variable, you want to simplify the equation down until you can't anymore. This equation is very simple. You just have to divide both sides by 6. This is because we want to get the variable (x) alone.

6x=36

Divide both sides by 6

x=6

Frederick make 7 × 7 quilt array

This shows that there are seven rows and there are seven columns.

So, the total quilt is

7 × 7 = 49 squares patches

We are told that each of this square patches are 3½ in long

Then, since it is a square patch, it's area is

A = S² = 3½ × 3½ = 12¼ in²

So, each square patch has an area of 12¼in²,

Then, for 49 square patches

The total area of 49 Square patches is

A = 49 × 12¼ = 600.25 in²

So, the area of the whole quilt is 600.25 in²

Answer:

The area of the whole quilt  is 600.25 ft²

Step-by-step explanation:

Here we have the length of each patch given as [tex]3\frac{1}{2} in[/tex]

Therefore, whereby the quilt had 7 × 7 array of different color square patches, we have;

Length of each side of quilt = [tex]7 \times 3\frac{1}{2} = 7 \times \frac{7}{2} = \frac{49}{2} = 24\frac{1}{2}[/tex]

∴ Area of the whole quilt = [tex]24\frac{1}{2} \times 24\frac{1}{2} = \frac{2401}{4} = 600\frac{1}{4} \ ft^2[/tex]

The area of the whole quilt  = 600.25 ft².

Answer:

134.0

Step-by-step explanation:

Final answer:

The volume of the hemisphere with a diameter of 8ft, rounded to the nearest tenth of a cubic foot, is approximately 134.0 cubic feet.

Explanation:

To find the volume of a hemisphere, we can use the formula:

Volume = (2/3) * π * (radius)^3

Given that the diameter of the hemisphere is 8ft, we can calculate the radius by dividing the diameter by 2:

Radius = 8ft / 2 = 4ft

Substituting the value of the radius into the formula, we get:

Volume = (2/3) * π * (4ft)^3

Volume ≈ 134.04 ft³ (rounded to the nearest tenth)

For day 2; he fill 5 + 5 cups

For day 3; he fill 5 + 5 + 5 cups

For day 4; he fill 5 + 5 + 5 + 5 cups

For day n; ?

The sequence is 5, 10, 15, 20, ...

The sequence increases linearly.

a = 5, d = 5, n = ?

Using the Formula for nth term of a sequence, we have:

[tex]T_{n} = a + (n - 1)d\\T_{n} = 5 + (n - 1) 5\\T_{n} = 5 + 5n -5\\T_{n} = 5 - 5 + 5n\\T_{n} = 5n[/tex]

i got it right

We have been given that the ages of students in a school are normally distributed with a mean of 15 years and a standard deviation of 2 years.

We are asked to find the percentage of students that are between 14 and 18 years old.

First of all, we will find z-score corresponding to 14 and 18 using z-score formula.

[tex]z=\frac{x-\mu}{\sigma}[/tex]

[tex]z=\frac{14-15}{2}[/tex]

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

[tex]z=-0.5[/tex]

Similarly, we will find the z-score corresponding to 18.

[tex]z=\frac{18-15}{2}[/tex]

[tex]z=\frac{3}{2}[/tex]

[tex]z=1.5[/tex]

Now we will find the probability of getting a z-score between [tex]-0.5[/tex] and [tex]1.5[/tex] that is [tex]P(-0.5<z<1.5)[/tex].

[tex]P(-0.5<z<1.5)=P(z<1.5)-P(z<-0.5)[/tex]

Using normal distribution table, we will get:

[tex]P(-0.5<z<1.5)=0.93319-0.30854[/tex]

[tex]P(-0.5<z<1.5)=0.62465[/tex]

Let us convert [tex]0.62465[/tex] into percentage.

[tex]0.62465\times 100\%=62.465\%\approx 62.5\%[/tex]

Therefore, approximately [tex]62.5\%[/tex] of the students are between 14 and 18 years old.
