Answer:

16x^2 - 8x - 3

Step-by-step explanation:

f(x) = 4x + 1

g(x) = 4x -3

f(x) * g(x) = (4x+1) * (4x-3)

(16x^2 - 12x + 4x -3)

Combine like terms

16x^2 - 8x - 3

that's your answer

The value of f (x) × g (x) will be;

⇒ 16x² - 8x - 3

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The value of function are,

⇒ f(x) = 4x + 1

⇒ g (x) = 4x - 3

Now.

Since, The value of function are,

⇒ f(x) = 4x + 1

⇒ g (x) = 4x - 3

Hence, We get;

⇒ f (x) × g (x) = (4x + 1) (4x - 3)

                    = 16x² - 12x + 4x - 3

                    = 16x² - 8x - 3

Thus, The value of f (x) × g (x)  = (16x² - 8x - 3)

Answer:

a) her estimate is wrong, because 22 crates can only contain 704 boxes

b) 23 crates

Step-by-step explanation:

Each crate can hold 32 boxes and there are total of 712 boxes.

Megan thinks she can fit all 712 boxes into 22 crates.

Now multiplying 22 crates 32 boxes to know the number of boxes22 crates can contain

= 22*32

= 704 boxes

The boxes are not all contacts in 22 crates

To pack 712 boxes

She Will need = 712/32 crates

She will need= 22.25 crates

Rounding up to whole number she will need 23 crates

Answer:

B) Approximately 50%

Step-by-step explanation:

In any distribution of data, the data can be divided into 4 main quarters that are approximately equal in percentage.

Thus, the first quartile consists of approximately 25%, the second is 25%, third quartile about 25%, while the fourth is 25% also.

Therefore, in a data set distribution of students, approximately 50% of the distribution of students will fall within the first and third quartiles.

Answer:

(B) Approximately 50%

Step-by-step explanation:

First quartile is 1/4 and that is 25% of students in the distribution.

Third quartile is 3/4 and that is 75% of students in the distribution.

Between the first quartile and third quartile is automatically, 50% of the students in the distribution. The answer is (B) Approximately 50%.

Answer:

[tex]\frac{3}{4}[/tex] miles

Step-by-step explanation:

Total length of the trail = [tex]4\frac{1}{2}[/tex] miles = [tex]\frac{9}{2}[/tex] miles

She ran the first [tex]\frac{2}{3}[/tex] of the distance i.e.

The distance for which she ran = [tex]\frac{2}{3} \times \frac{9}{2} = 3\ miles[/tex]

Remaining distance = Total length of trail minus the distance for which she has already run = [tex]\frac{9}{2} - 3 = \frac{3}{2}[/tex] miles

Given that: After running, Annie has to walk due to steep nature of the trail, So, Annie walked for [tex]\frac{1}{2}[/tex] of the remaining distance.

The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] Remaining distance

The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] [tex]\frac{3}{2}[/tex] = [tex]\frac{3}{4}[/tex] miles

So, the answer is: [tex]\frac{3}{4}[/tex] miles

  $2611.05

Step-by-step explanation:

  earnings = lane rentals + concessions

Friday:

  earnings = $842.72 +412.38 = $1255.10

Saturday:

We assume "down by 1/8" means the value was 1 -1/8 = 7/8 that of the previous day. Likewise, "increased by 1/2" is assumed to mean the value was 1 + 1/2 = 3/2 that of the previous day.

  earnings = 7/8×$842.72 + 3/2×412.38 = $1355.95

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

y = 4/3x - 5

Comparing with the general equation above

Slope/ m = 4/3

Since the lines are parallel their slope are also the same

So we have

Slope of parallel line = 4/3

Equation of the line using point (−6,−5) and slope 4/3 is

Answer:

Step-by-step explanation:

The time for each canoe is 3.5 hours

The total distance traveled by the first canoe is not known. Nor is the distance for the second canoe. We do know that the difference is 5.25 miles.

So let the rate of the slower canoe = x

Let the rate for the second canoe = 2x

The first canoe goes a distance of 2*x * 3.5 = 7x

The second canoe goes a distance of 3.5x

The difference = 7x - 3.5x = 5.25

3.5x = 5.25                                       divide by 3.5

x = 5.25/3.5

x = 1.5 which is the rate of the slower canoe

2x = 3  which is the rate of the faster canoe    

Answer:

a)after 1,000 years?

1 meter

b) 10 million years?

10,000 meters

c) 50 million years?

50,000 meters

Step-by-step explanation:

We are told in the question that mountains rise 1 mm per year.

a) After 1000 years

1 year = 1 mm

1000 years =

Cross Multiply

1000 × 1 mm

= 1000mm

Converting to meters

1 mm = 0.001 m

1000 mm =

1000 × 0.001m

= 1 meter

b) After 10 million (10,000,000) years

1 year = 1 mm

10000000years =

Cross Multiply

10000000 × 1 mm

= 10,000,000mm

Converting to meters

1 mm = 0.001 m

10,000,000mm =

10,000,000 × 0.001m

= 10,000 meters

c) After 50 million years(50,000,000)

After 50,000,000 years

1 year = 1 mm

50,000,000years =

Cross Multiply

50,000,000 × 1 mm

= 50,000,000mm

Converting to meters

1 mm = 0.001 m

50,000,000mm =

50,000,000 × 0.001m

= 50,000 meters

Answer:

1/4

Step-by-step explanation:

Hello, first of all we could say, let 's replace x by 1 and see if we can conclude.

numerator gives [tex]\sqrt{1+15}-4=\sqrt{16}-4=4-4=0[/tex]

denominator gives 1-1=0

So, this is 0/0 and this is not defined.

We need to ask a friend for help. Guillaume de l'Hôpital, French mathematician from the 1600s,  has a trick to solve this kind of stuff.

In short, he says that

[tex]\displaystyle \lim_{x\rightarrow c} \ {\dfrac{f(x)}{g(x)}}=\lim_{x\rightarrow c} \ {\dfrac{f'(x)}{g'(x)}}[/tex]

In our case here, we have c = 1

[tex]f(x)=\sqrt{x^2+15}-4\\\\g(x)=x-1[/tex]

[tex]f'(x)=\dfrac{1}{2}\dfrac{2x}{\sqrt{x^2+15}}=\dfrac{x}{\sqrt{x^2+15}}\\\\f'(1)=\dfrac{1}{4}\\\\g'(x)=1\\\\\dfrac{f'(1)}{g'(1)}=\dfrac{1}{4}[/tex]

So, we can conclude

[tex]\displaystyle \lim_{x\rightarrow1} \ {\dfrac{\sqrt{x^2+15}-4}{x-1}}=\lim_{x\rightarrow1} \ {\dfrac{1}{4}}=\boxed{\dfrac{1}{4}}[/tex]

Axis of Symmetry: x = -4

Vertex: (-4, 54)

Step-by-step explanation:

We use a graphing calc.

Answer:

the equation of the axis of symmetry is [tex]x=-4[/tex]

Step-by-step explanation:

Recall that the x-value of the vertex of a parabola of the form:

[tex]y=ax^2+bx +c[/tex]

is given by the expression:

[tex]x_{vertex}=-\frac{b}{2\,a}[/tex]

therefore, in our case the x-position of the vertex becomes;[tex]x_{vertex}=-\frac{b}{2\,a}=\frac{32}{-8} =-4[/tex]

and since the equation of the axis of symmetry is [tex]x=x_{vertex}[/tex]

Then, the equation of the axis of symmetry is [tex]x=-4[/tex]

Answer:

The cosine of angle C is 5/13, or approximately 0.38.

Step-by-step explanation:

To solve this problem, we must remember what the cosine of an angle represents.  The cosine of an angle is equal to the ratio of the adjacent side divided by the hypotenuse.

From the diagram, we can determine that the adjacent side length is 10 and the hypotenuse is 26.

Therefore, the cosine of angle C is:

10/26 = 5/13 (simplified)
