Help please and thank you (Algebra 1)

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:

Ratio of area = 16:25

Step-by-step explanation:

ar(ABC)/ar(DEF) = side²/side'²

16/25 = s²/s'²

√(16/25) = s/s'

4/5 = s/s'

Ratio of side are 4:5

Answer:

x = -15/4

Step-by-step explanation:

1 - 4/3x = 1/2(-x + 7)

~Simplify

1 - 4/3x = -1/2x + 7/2

~Subtract 1 from both sides

-4/3x = -1/2x + 5/2

~Add 1/2x to both sides

-2/3x = 5/2

~Multiply -3/2 to both sids

x = -15/4

[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]

I hope this helps!

Answer:

In algebra, like terms are terms that have the same variables and powers. ... Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

Answer:

These are not like terms.

Step-by-step explanation:

Although their variables are the same, the exponents are different.  LIke terms must have the same variables AND same exponents.  The first term's variables are: x raised to the second power times y, while the other term's variables are:  y times x times 2

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:

C

Step-by-step explanation:

Because it has no pattern, isnt repeating, and isnt a whole number.

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.

We have that The height as a linear function of time is

[tex]x=-27.5T+500[/tex]

From the Question we are told that

Time t=8 minutes

Height h=500

Descended height h_d= 280 feet.

Generally the equation for the linear function  is mathematically given as

Let

Height as a linear function =x

[tex]x=\frac{h_d-h}{t}*T+h[/tex]

[tex]x=\frac{280-500}{8}*T+500[/tex]

[tex]x=-27.5T+500[/tex]

In conclusion

The height as a linear function of time is

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
