Answer:
the theoretical probability is 1/5.
the experimental probability is 3/10.
chances are the experimental probobility will approach the theoretical probobility.
Step-by-step explanation:
since blue is one of five equal sizes, the probobility that it will land on blue is 1/5.
the expiromental probobility is the number of times it landed on blue devided by the number of spins. 15/50. this can be simplified by pulling out a 5, leaving us with 3/10.
last it stands to reason that the more times the spinner is spun the closer the experimental probability will model the theoretical probability.
1. How are sine functions connected to the unit circle?
2. How are cosine functions connected to the unit circle?
Answers
Answer:
1) The sine function relates a real number t to the y-coordinate of the point where the corresponding angle intercepts the unit circle.
2) The secant function is the reciprocal of the cosine function (secx=1cosx) x = 1 cos .The co-secant function is the reciprocal of the sine function (cscx=1sinx) x = 1 sin . It can be found for an angle t by using the y -coordinate of the associated point on the unit circle: csct=1y t = 1 y .
Step-by-step explanation:
Final answer:
Sine and cosine functions are related to the unit circle with their values representing the y and x coordinates of a point on the circle, respectively. They oscillate between +1 and -1, repeating every 2π radians and are used to model simple harmonic motion, differing by a phase shift of π/2 radians.
Explanation:
The sine and cosine functions are directly related to the unit circle, which is a circle with a radius of 1 centered at the origin of a coordinate system. When an angle θ is drawn from the positive x-axis, the coordinates of the point where the terminal side of the angle intersects the unit circle are (cos θ, sin θ).
For the sine function, think of it as projecting the point on the unit circle onto the y-axis. This projection gives the y-coordinate, which is the sine of the angle θ. Therefore, the sine function oscillates between +1 and -1 as the angle θ increases, repeating every 2π radians because this is the circumference of the unit circle.
Similarly, the cosine function is obtained by projecting the point onto the x-axis, providing the x-coordinate or the cosine of the angle θ. It also oscillates between +1 and -1 and repeats every 2π radians. Both sine and cosine functions describe simple harmonic motion when modeling periodic phenomena, and they differ by a phase shift of π/2 radians.
The initial conditions of a sine function with zero phase shift are that the function starts at 0, indicating that, for simple harmonic motion, the initial position is at equilibrium. With a cosine function, the initial value is 1 when the phase shift is zero, indicating that the motion starts at its maximum displacement. This concept can also be used to model wave functions and determine scalar components using triangles.

Given the sequence.
125, 25, 5, ...
Write the rule an using the geometric sequence formula:
Answers
The given sequence follows a geometric pattern, and the common ratio is 0.2. Using the geometric sequence formula, we can find any term in the sequence by substituting the values into the formula.
Explanation:The given sequence 125, 25, 5, ... follows a geometric pattern where each term is obtained by multiplying the previous term by a common ratio. To find the common ratio (r), we divide any term by its previous term. Let's divide 25 by 125 to find the common ratio: r = 25/125 = 1/5 = 0.2.
Now that we have the common ratio, we can use the formula for a geometric sequence:
aₙ = a₁ × r(n-1)
Here, aₙ represents the nth term, a₁ is the first term, r is the common ratio, and n is the term number. Since the first term (a₁) is 125 and the common ratio (r) is 0.2, we can substitute these values into the formula to find the nth term.

The rule for the given geometric sequence 125, 25, 5, ... is an = 125 × 5(n-1).
Explanation:The given sequence is 125, 25, 5, ...
To find the rule using the geometric sequence formula, we need to determine the common ratio. The common ratio is found by dividing any term by its previous term. Let's take the first two terms: 125/25 = 5. So, the common ratio is 5.
The formula for a geometric sequence is given by: an = a¹ × r⁽ⁿ⁻¹⁾, where an is the nth term, a¹ is the first term, r is the common ratio, and n is the position of the term.
Using this formula with the first term (a¹ = 125) and the common ratio (r = 5), we can find the rule for the sequence. Let's find the rule for the third term: a³ = 125 × 5⁽³⁻¹⁾ = 125 × 5² = 125 × 25 = 3125.
Therefore, the rule for the sequence is: aⁿ = 125 × 5⁽ⁿ⁻¹⁾.

Answers
Slope of the line passes through (5,10) and (7,12) is 1.
Step-by-step explanation:
Given,
The two points are (5,10) and (7,12).
To find the slope passing through the given points.
Formula
The slope of the line passing through ([tex]x_{1} ,y_{1}[/tex]) and ([tex]x_{2} ,y_{2}[/tex]) is [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Now, putting [tex]x_{1} =5,y_{1}=10, x_{2}=7, y_{2} =12[/tex] we get,
Slope = [tex]\frac{12-10}{7-5}[/tex] = [tex]\frac{2}{2}[/tex] = 1
Hence,
Slope of the line passes through (5,10) and (7,12) is 1.

A lomy owner has his own fuel supply and needs to refill his storage tank. He has just completely
filled the fuel tank of the lorry with 170 litres from empty. He now has 100 litres of fuel left in his
storage tank. With the price of fuel expected to fall soon he only wants to buy enough for the next
fortnight. Normally his regular short daily trips total 300 km and this leaves just 20 litres in the
lorry's fuel tank. He expects to complete three regular days of 300 km journeys each week, but
this could rise to five. Sometimes the total journeys are longer but his daily trips never total more
than 400 km in a day. He never works more than five days in a week. His storage container holds
4000 litres
How much fuel should he order to be certain that he has enough for the next two weeks?
Answers
Answer: He should order for 1046.67 litres fuel to be certain that he has enough for the next two weeks
Step-by-step explanation:
Note that he has just completely
filled the fuel tank of the lorry with 170 litres from empty. He now has 100 litres of fuel left in his storage tank
If his regular short daily trips total 300 km and this leaves just 20 litres in the lorry's fuel tank.
That is 100 litres -20 litres = 80 litres
On 300km, he consumed 80 litres
He plans to complete three regular days of 300 km journeys each week, but this could rise to five. Sometimes the total journeys are longer but his daily trips never total more than 400 km in a day. He never works more than five days in a week. His storage container holds
4000 litres
From all these analysis, we can deduce that the maximum km of journey he should prepare for is
400km × 5 = 2000km for one week
Since he consumed 80 litres of fuel for any 300km
Then,
80/300 = L/2000
L = 1600/3
L = 533.33 litres
The journey for two weeks will be
533.33 × 2 = 1066.67 litres
Recall that he left 20 litres in the tank. Take this away from 1066.67 litres.
1066.67 - 20 = 1046.67 litres
He should therefore order for 1046.67 litres fuel to be certain that he has enough for the next two weeks
When brad was born ,his grandma put 1,500 in a new account for him . Since then the balance of the account has grown by 6.5% each year with no deposits or withdrawals. Now Brad is 18 and can withdraw the money if he decides to wait until his 21st birthday how much more money will be in the account
Answers
Final answer:
Using the compound interest formula, Brad's $1,500 will grow to $1,810.69 by the time he turns 21 due to the 6.5% annual growth rate for three additional years.
Explanation:
Calculating Future Value with Compound Interest
Brad's grandmother initially deposited $1,500 in an account that grows at a rate of 6.5% each year. To calculate the future value of this investment when Brad is 21, we'll use the formula for compound interest:
FV = P(1 + r)^n
Where:
FV is the future value of the money after n years.
P is the principal amount (the initial amount of money).
r is the annual interest rate (decimal).
n is the number of years the money is invested or borrowed for.
In Brad's case:
P = $1,500
r = 0.065 (6.5% converted to a decimal)
n = 21 years old - 18 years old = 3 years
Now, we plug these values into the compound interest formula:
FV = $1,500(1 + 0.065)^3
And calculate the future value.
Therefore, if Brad decides to wait until his 21st birthday to withdraw the money, he would have:
$1,500(1 + 0.065)^3 = $1,500(1.065)^3 = $1,500 * 1.207127 = $1,810.69
Brad will have $1,810.69 in his account by the time he is 21 if he waits, which is more than he would have at 18.

Line B is 55 cm long. It is an enlargement of Line A which is 5 cm long. What is the scale factor of the enlargement?
Answers
Answer:
11
Step-by-step explanation:
Line B is an enlargement of Line A, which is 5 cm long. Let's say that the scale factor is "k". Then, when we multiply k by the length of Line A, we should get the length of Line B:
(Line A length) * k = (Line B length)
5 * k = 55
k = 55/5 = 11
Thus, the scale factor is 11.
Hope this helps!
Answer:
11
Step-by-step explanation:
Length of enlarged line is: 55 cm
Length of the original line: 5 cm
