A truck is moving at a rate of 105 kilometers per hour and the diameter of its wheels is 1 meter find the angular speed of the wheels in radians per minute
The angular speed of the truck's wheels is 3500 radians per minute, calculated by dividing the linear speed in meters per minute by the wheel's radius in meters.
Explanation:To calculate the angular speed of the truck's wheels in radians per minute, we first need to understand the relationship between linear speed and angular speed. Angular speed (
adians) is given by the formula
adians = linear speed (v) divided by the radius of the wheel (r).
First, we convert the truck's speed from kilometers per hour to meters per minute:
105 km/hr = (105 * 1000 meters) / (60 minutes) = 1750 meters/minute.
Since the diameter of the wheel is 1 meter, the radius (r) is half of that, which is 0.5 meters.
Now we can calculate the angular speed:
adians = v / r = 1750 m/min / 0.5 m which gives us 3500 rad/min.
Therefore, the angular speed of the wheels is 3500 radians per minute.

Is it true that a continuous function that is never zero on an interval never changes sign on that interval? give reasons for your answer?
Yes, It is true that a continuous function that is never zero on an interval never changes its sign on that interval.
What is a continuous function?In mathematics, a continuous function is a function such that a continuous variation of the argument causes a continuous variation of the value of the function. This indicates that there aren't any discontinuities or sudden changes in value.
Unchanged sign is a property of continuous functions that are never zero on an interval, hence this is true. This is due to the perennially significant Intermediate value theorem.
Therefore, It is true that a continuous function that is never zero on an interval never changes its sign on that interval.

An iron fence reacts with the oxygen in the air to form rust. The formation of rust is an oxidation-reduction reaction and a _____ reaction.
A. decomposition
B.combustion
C. synthesis
D. single-replacement
The formation of rust on an iron fence is a synthesis reaction, where iron combines with oxygen in the air to create iron oxide. During this process, iron is oxidized and oxygen is reduced, making it an oxidation-reduction (or redox) reaction.
Explanation:The formation of rust is an oxidation-reduction reaction and a synthesis reaction. Rusting occurs when iron reacts with oxygen in the air, typically in the presence of water, to form iron oxide.
The process can be summarized as iron (Fe) being oxidized to iron(II) ions (Fe2+) which react further with oxygen and water to produce a hydrated iron(III) oxide, commonly known as rust (Fe2O3·xH2O).
This process is classified as a synthesis reaction because it involves the combination of simpler substances - iron and oxygen - to form a more complex compound, namely iron oxide.
In comparison to other types of reactions, decomposition refers to a single compound breaking down into two or more simpler compounds or elements.
Combustion reactions involve fuel (often a hydrocarbon) reacting with oxygen to produce carbon dioxide and water.
Lastly, single-replacement reactions occur when an element replaces another element in a compound. Since the reaction of iron with oxygen adds oxygen to create a new product, rather than decomposing, combusting, or substituting, it is indeed a synthesis reaction.

What is the number of x intercepts of the parabola with equation y=6x^2-4x-3?
The parabola y=6x^2-4x-3 has 2 x-intercepts. This is determined by solving the equation for when y equals zero, using the quadratic formula. Because the discriminant is positive, there are two distinct real solutions, indicating the two x-intercepts.
Explanation:To find the number of x-intercepts of the parabola with equation y=6x^2-4x-3, you need to set y to 0 and solve the equation for x. The solutions for x will be the x-coordinates of the intercepts.
The x-intercept(s) occur where y=0. The quadratic formula, x = [-b ± sqrt(b^2 - 4ac)]/2a is used to find these points.
Substituting the coefficients a=6, b=-4, and c=-3 into the formula, we get:
x = [4 ± sqrt((-4)^2 - 4*6*(-3))]/(2*6)
This simplifies to x = [4 ± sqrt(16+72)]/12 = [4 ± sqrt(88)]/12
Since the value under the square root (the discriminant) is positive, we have two distinct real solutions for x. This means that the parabola crosses the x-axis at two points, so there are 2 x-intercepts.

We have been given that Rosa brought d drawings to an art show.
After selling 14 of them, she had 34 left.
We have to form a equation such that when we add 14 in 34 we get the total of drawings.
[tex]d-14=34[/tex] (1)
Equation (1) shows that when we add sold drawing we get the total drawings.
Answer:

A new car dealer offered to sell his demonstrator model for 80% of the retail price. If the retail price is $30,863, how much did the customer save?
Answer:
The customer saved $6,167.20
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
To begin solving this problem we need to change the percent into decimal form. We can do this by moving the decimal point 2 digits to the left like so...
80.0% ⇔ 0.80
Now that we have the percent in decimal form we can find how much the customer paid by multiplying the percent by the retail price.
[tex]30,836 * 0.80 = 24,668.80[/tex]
Now that we have the amount the customer paid, we can subtract that value by the retail price of the model to calculate how much the customer saved.
[tex]30,836-24668.80 = 6,167.20[/tex]
Finally, we can see that the customer saved $6,167.20
