Need help explaining why this happens

Answer:

4

Step-by-step explanation:

To find the degree of a polynomial, identify the term with the greatest exponent. The exponent of that term is the degree of the polynomial.

In the given polynomial 5x⁴+4x²+2x+1​, the term with the greatest exponent is 5x⁴. This term has an exponent of 4, so therefore, the degree of the polynomial is 4.

Answer:

√40 is an irrational number

Step-by-step explanation:

"An irrational number is a real number that cannot be expressed as a ratio of integers, for example, √ 2 is an irrational number."

Here we have some given restrictions that affect the number of medals, using these, we want to find the maximum number of bronze medals that can be awarded.

We will find that:

The maximum number of bronze medals that can be awarded is 535

Now let's see how we can get that.

Let's define the variables:

G = number of gold medals.

S = number of silver medals.

B = number of bronze medals.

Now we can see what information we have.

There are 2021 participants.

The number of silver medals is at least twice the number of gold medals.

S ≥ 2*G

The number of bronze medals is at least twice the number of silver medals:

B ≥ 2*S.

The number of all medals is not more than 40% of the number of participants.

The total number of medals is (G + S + B)

40% of the total number of participants is:

(40%/100%)*2021 = 0.4*2021 = 808.4

Then we have:

G + S + B ≤ 808.4

We can rewrite the above inequality as:

G + S + B ≤ 808.

Then we have 3 inequalities:

S ≥ 2*G

B ≥ 2*S

G + S + B ≤ 808

Now we want to maximize the number of gold medals.

This means that the total number of medals should be exactly 808 (the maximum number of total medals) so we have:

G + S + B = 808.

Also, if we want to maximize the number of gold medals, then we need to minimize the number of silver medals and the number of bronze medals, such that we get:

S = 2*G

B = 2*S

Now we have 3 equations:

G + S + B = 808

S = 2*G

B = 2*S

Replacing the third equation in the first one, we get:

G + S + 2*S = 808

G + 3*S = 808

Now we can replace:

S = 2*G

in the above equation to get:

G + 3*(2*G) = 808

G + 6*G = 808

7*G = 808 =

G = 808/7 = 115.43

But we can have 0.43 of a gold medal, so we need to round down to the next whole number:

G = 115

Now, with this restriction, we want to find the maximum number of bronze medals.

This means that we need to minimize the number of silver medals, so we use:

S = 2*G = 2*115 = 230

And the number of bronze medals will be such that:

B + G + S  = 880

B + 115 + 230 = 880

B = 880 - 115 - 230 = 535

The maximum number of bronze medals that can be awarded is 535

[tex]y=\displaystyle -\frac{1}{4}x+\displaystyle \frac{15}{4}[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.

1) Determine the slope (m)

[tex]m=\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

In the graph, two points are indicated: (-5,5) and (3,3). Plug these into the equation:

[tex]m=\displaystyle \frac{3-5}{3-(-5)}\\\\m=\displaystyle \frac{3-5}{3+5}\\\\m=\displaystyle \frac{-2}{8}\\\\m=\displaystyle \frac{-1}{4}[/tex]

Therefore, the slope of the line is [tex]\displaystyle -\frac{1}{4}[/tex]. Plug this into  [tex]y=mx+b[/tex]:

[tex]y=\displaystyle -\frac{1}{4}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=\displaystyle -\frac{1}{4}x+b[/tex]

Plug in one of the points we used earlier and solve for b:

[tex]3=\displaystyle -\frac{1}{4}(3)+b\\\\3=\displaystyle -\frac{3}{4}+b\\\\3+\displaystyle \frac{3}{4}=b\\\\\frac{15}{4} =b[/tex]

Therefore, [tex]\displaystyle \frac{15}{4}[/tex] is the y-intercept. Plug this back into [tex]y=\displaystyle -\frac{1}{4}x+b[/tex]:

[tex]y=\displaystyle -\frac{1}{4}x+\displaystyle \frac{15}{4}[/tex]

Answer: y = (-1/2)x + 2

Concept:

When two lines are perpendicular to each other, their slopes are negative reciprocals.

The reciprocal of a number is 1 divided by the number.

In other words, it is the image opposite of a term.

Solve:

Given information

Given line = y = 2x - 5

Point = (-4, 4)

Find the slope of the line

Given the line is perpendicular to the line y = 2x - 5, the slope of the line would be negative reciprocal of the line y = 2x - 5.

Slope of line [y = 2x - 5] = 2

Slope of new line = (-1/2)

Find the y-intercept by substituting the given point

Equation of the new line: y = (-1/2)x + b

y = (-1/2)x + b

4 = (-1/2) (-4) + b

4 = 2 + b

4 - 2 = 2 + b - 2

b = 2

Finalize the equation of the line

Slope = -1/2

Y-intercept = 2

[tex]\boxed{y=-\frac{1}{2}x+2 }[/tex]

The motion of a Ferris wheel, spinning about a fixed axis is rotational motion

a) Please find attached the height vs time graph of ONE cycle of Bert's motion on the ride, showing 5 Key points, including; The period, amplitude, the vertical shift, horizontal shift, the neutral axis

b) The equation to represent Bert's journey is h(t) = 6·sin(3.6·(t - 25)) + 7

The reason the above equation are correct are:

The given parameters of the Ferris wheel are;

Radius, r = 6 meters

The height of the axle above the ground, h = 7 metres

The time it takes to complete one revolution, T = 100 seconds

The level at which Bert enters the Ferris wheel = The lowest level

The time at which the ride starts = 0 seconds

a) The graph of a Ferris wheel is a graph sinusoidal function with the following details

The general form of the sinusoidal function is, y = a·sin(b·(t - h)) + D

Amplitude = The radius = 6 meters

The vertical shift, D = The elevation of the axle above the ground = 7 meters

The period, T = 360/b

∴ b = 360/T = 360/100 = 3.6

At t = 0, sin(b·(t - h)) = -1

Given that sin(-90) = -1

Therefore; (3.6·(0 - h)) = -90

π/50 = -π/2

-h = -25

∴ The horizontal shift, h = 25

The function of the Ferris wheel is y = 6·sin(3.6·(t - 25)) + 7

The graph of the function is created on MS Excel, using the above sinusoidal equation of the Ferris wheel

The 5 key points included in the graph are;

b) The appropriate equation of the sinusoidal function of the Ferris wheel is determined from the general sinusoidal function equation, y = a·sin(b·(t - h)) + D, as follows;

From part (a);

a = 6, b = 3.6, h = 25, and D = 7

The equation of the sinusoidal function h(t) to represent Bert's journey, is h(t) = a·sin(b·(t - h)) + D

Where;

h = The height of the Ferris Wheel

t = The time in seconds

a = The amplitude = 7

b = The 360/(The period) = 3.6

h = The horizontal shift = 25°

D = The vertical shift = 7 meters

The MOST appropriate equation of the sinusoidal function h(t) is therefore;

h(t) = 6·sin(3.6·(t - 25)) + 7

Answer:

A.) w² + 3w in²

B.) 28 in²

Step-by-step explanation:

A.)

Let w = width and l = length.

    The area of a rectangle can be written as length · width (base · height). The problem informs us that the length of the rectangle is 3 inches greater than the width. Therefore, l can also be written as w + 3. We can use this to form a polynomial that represents the area of the rectangle.

A(rectangle) = lw = (w + 3) · w = w² + 3w

B.)

Use the polynomial we previously found to find the area.

A(rectangle) = (4)² + 3(4) = 16 + 12 = 28 in²

Answer:

Alice drives 168.26 miles daily and 841.3 miles per 5 days on her regular route when there is no detour.

Step-by-step explanation:

First, we need to divide 927.8 miles by 5.

927.8 ÷ 5 = 185.56 is her daily mileage, including the detour.

Since her detour added 17.3 miles to her daily mileage, we need to subtract this from her current daily mileage.

185.56 - 17.3 = 168.26 is her daily mileage when there is no detour.

Now, in order to find her mileage for 5 days, we need to multiply this number by 5.

168.26 x 5 = 841.3

Therefore, Alice drives 168.26 miles daily and 841.3 miles per 5 days on her regular route when there is no detour.

Answer: Rational number

It is a rational number because it is a fraction of two integers. Those two integers being -15 and 2.

In general, any rational number is of the form P/Q where P and Q are integers. The Q cannot be zero. Another example of a rational number is 2/3. In this example, P = 2 and Q = 3.

Going back to -15/2, we would have P = -15 and Q = 2.

The fraction -15/2 is not a whole number nor is it an integer. This is because -15/2 = -7.5 and this is sufficient to see we don't have an integer result. We would need to have nothing after the decimal point to get a whole number.
