a race car has wheels with diameter 66 cm. if a formula 1 car is in a 300 km race, how many times must the tires turn to cover the race distance?
A race car with wheels with diameter 66 cm must turn 1,088,000 times to cover a 300 km race. This is because the circumference of a wheel is equal to its diameter multiplied by pi, which is approximately 3.14.
So, the circumference of a 66 cm wheel is 66 * 3.14 = 208.2 cm. To travel 300 km, the car must turn its wheels 300,000 / 208.2 = 1,445 times.
The circumference of a circle is equal to its diameter multiplied by pi, which is approximately 3.14. So, the circumference of a 66 cm wheel is 66 * 3.14 = 208.2 cm. To travel 300 km, the car must turn its wheels 300,000 / 208.2 = 1,445 times.
In other words, the car must turn its wheels 1,445 times to cover the race distance. This is a lot of turns, but it is possible for a Formula 1 car to do this. The cars are designed to be very efficient and to have very low rolling resistance, which means that they can turn their wheels very quickly without losing too much energy.

given: pfst is a rectangle, m∠sot=60°, os = r=4 find: st and pt
The dimensions of the provided rectangle's sides ST and PT are 4 and 4√3 units, respectively.
Given: PFST is a rectangle with a radius of four and angle SOT of 60 degrees.
We must locate ST and PT.
We will thus apply the idea of cosine of an angle to find the same.
The law of cosine is expressed as follows for a triangle with sides α, β, and γ with angles, and:
[tex]\mathrm {b^2=a^2+c^2-2ac\cdot \cos \left(\beta \right)}[/tex]
Since the radius of the circle O is made up of the points OS, OP, OF, and OT, their measurements are all equal.
Now, considering the Δ SOT for ST.
We have,
β = 60° and a and c = 4.
Applying the law:
[tex]\mathrm b=\sqrt{4^2+4^2-2\cdot \:4\cdot \:4\cos \left(60^{\circ \:}\right)}[/tex]
Solving we get,
b = 4
Therefore, ST = 4 units.
Similarly, considering the Δ POT for PT.
Here, ∠POT = 180° - 60° [linear pair]
∠POT = 120°
So, we have,
β = 120° and a and c = 4.
Applying the law:
[tex]\mathrm b=\sqrt{4^2+4^2-2\cdot \:4\cdot \:4\cos \left(120^{\circ \:}\right)}[/tex]
Solving we get,
b = 4√3 units
Therefore, PT = 4√3 units.

An advertisement for a new toothpaste states that 64% of users reported better dental checkups. The results of the poll are accurate within 3.4 percent points, 9 times out of 10. (A) State the confidence level. (B) Determine the confidence interval. (C) If all 32 students in a mathematics class used this toothpaste, determine the range of the mean number of classmates who could expect better dental checkups.
(A) The confidence level for the results of the poll is 90%
(B) The confidence interval is (58.411, 69.589).
(C) The range of the mean number of classmates who could expect better dental checkups is approximately 1867 to 2229.
(A) The confidence level for the results of the poll is 90%. This means that there is a 90% probability that the true percentage of users reporting better dental checkups falls within the stated range.
(B) To determine the confidence interval, we need to consider the margin of error. The margin of error is calculated by multiplying the critical value (obtained from a standard normal distribution table) by the standard deviation of the sample proportion. In this case, the standard deviation is determined by the given accuracy of 3.4 percent points.
Using a critical value of 1.645 (corresponding to a 90% confidence level), we can calculate the margin of error as 1.645 times 3.4, which equals 5.589.
To find the confidence interval, we subtract and add the margin of error from the reported percentage of users who reported better dental checkups. Subtracting 5.589 from 64 gives us a lower bound of 58.411, and adding 5.589 gives us an upper bound of 69.589. Therefore, the confidence interval is (58.411, 69.589).
(C) If all 32 students in a mathematics class used this toothpaste, the range of the mean number of classmates who could expect better dental checkups can be calculated by applying the confidence interval to the sample size. Taking the lower bound of the confidence interval (58.411) and multiplying it by 32, we get 1867.552. Rounding down, we have a minimum estimate of 1867 classmates who could expect better dental checkups.
Similarly, multiplying the upper bound of the confidence interval (69.589) by 32 gives us 2228.448. Rounding up, we have a maximum estimate of 2229 classmates who could expect better dental checkups.
Therefore, the range of the mean number of classmates who could expect better dental checkups is approximately 1867 to 2229.

Find the linear polynomial p(x) = djx + do, = that interpolates the two points with coordinates (3,0) and (4, -3). The coefficients of p(x) are aj = ao =
In order to interpolate between the two points (3,0) and (4,-3), the linear polynomial p(x) is equal to -3x + 3, and this equation is employed. The value of the constant term is 3, but the value of the coefficient x is -3.
A linear polynomial is a type of polynomial that has only one degree of complexity. This suggests that it can be stated using the formula p(x) = axe + b, where a and b are values that continue to be the same. a and b are values that remain unchanged. These two sentences inform us that the value of p(3) is zero, and that the value of p(4) is negative three. When we enter these values into the equation p(x) = axe + b, we obtain the two equations that are presented further down in this section:
0 = 3a + b -3 = 4a + b
Following the resolution of the equations for a and b, we find that the respective solutions are a = -3 and b = 3. Since this is the case, the linear polynomial p(x) that interpolates the two points (3,0) and (4,-3) is -3x + 3, as was demonstrated in the preceding sentence.

a polynomial function h(x) has a zero of x = 3 – 4i with a multiplicity of one. certain values of h(x) are given in the following table.
The polynomial function h(x) has a complex zero at x = 3 – 4i with a multiplicity of one. The given table provides certain values of h(x) for various x-values.
A zero of a polynomial function corresponds to the values of x for which the function evaluates to zero. In this case, the zero is x = 3 – 4i, where 4i represents the imaginary unit multiplied by 4. The multiplicity of one indicates that this zero occurs only once in the function.
The table provides specific values of h(x) for different x-values, which allows us to observe the behavior of the function. However, without knowing the functional form of h(x) or additional information, we cannot determine the complete polynomial equation.
To fully determine the polynomial function h(x) based on the given zero, we need to know all of its zeros, including any real or complex zeros with their respective multiplicities. Additionally, the degree of the polynomial can affect the number of zeros it possesses. With this information, we could reconstruct the polynomial equation using methods such as factoring, synthetic division, or the quadratic formula.

DEPRECIATION The value of a new tractor decreases by 20% each year. The initial cost of a tractor is $38,000. Write a function f(t) that can be used to project the value of the tractor t years in the future.
Answer:
y = 0.20x(-38,000) + 38,000
Step-by-step explanation:
y: represents how much the price is now.
x: Represents the number of years passed.
y = 0.20x(-38,000) + 38,000
For example if it's 1 year
y = 0.20(1) (-38,000) + 38,000
y = 0.20(-38,000) + 38,000
y = -7600 + 38,000
