1) Alice is a truck driver who drives the same route every day for 5 days. On the
last day she takes a detour that adds 17.3 miles to her daily mileage. At the end
of the 5 days, Alice has driven 927.8 miles. How many miles does Alice drive on
her regular route when there is no detour?
Answers
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.

write down the degree of given polynomial 5x⁴+4x²+2x+1
Answers
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.

Answers
Answer:
[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!

Bert is on a Ferris wheel. The radius of the Ferris wheel is 6 metres. Its axle is 7 metres above the ground. It takes 100 seconds to complete one full revolution. Bert enters the Ferris wheel at its lowest height. The ride starts at 0 seconds.
Work or explanation must be provided for full marks. Answers involving radians will result in a mark of zero.
a) Sketch a height vs time graph of ONE cycle of Bert’s motion on the ride. Show at least 5 KEY POINTS and label them on your graph.
b) Determine an equation of the sinusoidal function h(t) to represent Bert’s journey, where h represents the height of the Ferris Wheel and t represents the time in seconds.
Choose the MOST appropriate sinusoidal function based on the information provided.
Answers
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;
The period, THorizontal shift, hAmplitude, aNeutral axisVertical shift, Db) 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

Is -15/2 a rational number or integer or whole number or all of them??
Answers
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.
