How much meters per second did the cyclist travel from 8 a.M. To 10 a.M? (*TIP: 2 hours = 7200 seconds, 2 km= 2000 m). Give the formula used, show your working and round off your answer to two decimal places. Don't forget the unit! *
Answer:
0.28 meters per second.
Step-by-step explanation:
We have that the speed formula is as follows:
v = d / t
In this case they tell us that the distance is 2 km the equivalent of 2000 meters and the time is 2 hours the equivalent of 7200 seconds, we replace and we are left with:
v = 2000/7200 = 0.28
Therefore it ran 0.28 meters per second.

suppose you are asked to guess a number between 1 and 15 (inclusive), and after each guess you are told whether it is higher or lower. what is the minimum number of guesses required to guarantee that you know the number?
3 is the minimum number of guesses required to guarantee that you know the number.
If we use a binary search approach, we can guess the number in a minimum number of steps.
First, we guess the middle number, which is 8. If the answer is higher, we can eliminate all the numbers from 1 to 8, because they are lower than the answer.
Then we guess the middle number of the remaining numbers, which is 12. If the answer is lower, we can eliminate all the numbers from 12 to 15, because they are higher than the answer.
We have now eliminated half of the remaining numbers, and we are left with 6 and 7. We can guess either of these numbers, and we will know the answer with a total of three guesses.
Therefore, we can guarantee that we know the number in three guesses using this binary search approach.

(-2,3), (0,1), (2,-4), (3,-1), (2,4) IS IT AN FUNCTION OR NOT
Answer: No
Explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.
In the relation shown here, notice that
the x-coordinate 2 appears twice.
In one case, 2 corresponds to -4 and in
the other case, 2 corresponds to -4.
Since the x-coordinate 2 corresponds to more than one
y-coordinate, no, this relation is not a function.
A fish tank is in the shape of an open glass cuboid 30 cm deep with a base 16 cm by 17 cm, these measurements being external. If the glass is 0.5 cm thick and its mass is 3 g/cm3, find a the capacity of the tank in litres, and the mass of the tank in kg.
Answer:
3.24 kg
Step-by-step explanation:
internal Vol = (30-0.5)(16-1)(17-1) = 7080 cm^3 = 7.08ltrs
external Vol= 30* 16* 17 = 8160cm^3 = 8.16ltrs
Vol of thickness = 8160 - 7080 = 1080cm^3
Mass of the tank= density * volume = 3*1080 = 3,240g = 3.24 kg
when solving proportions, we set the cross products equal and then we _____________.
When solving proportions, we set the cross products equal, and then we solve for the unknown variable.
When solving proportions, we set the cross products equal to each other and then proceed to solve for the unknown variable. A proportion is an equation that states that two ratios or fractions are equal. To solve a proportion, we first identify the two ratios involved and set their cross-products equal.
For example, consider the proportion: a/b = c/d
To solve for the unknown variable, we set the cross products (a * d) and (b * c) equal:
a * d = b * c
This equation allows us to find the value of the unknown variable by manipulating the equation through multiplication or division to isolate the variable on one side of the equation.
By setting the cross products equal, we essentially establish an equality between the two ratios, indicating that the fractions on either side of the proportion are equivalent. Solving for the unknown variable allows us to determine its value based on the relationship between the given ratios.

A sector with an angle 110° at the centre of a circle is cut away from a circular piece of paper of radius 7cm. the remaining part is folded to forming a cone
1; find the vertical angle
2:the angle of sector
The required vertical angle and angle of the sector is 110° and the arc length of the sector is 11 cm.
Given that the central angle of the sector is 110° and the radius of the circle is 7 cm.
To find the arc length when central angle (a) and radius (r) of the circle is given by using the formula,
Arc length (A) = a/360 × 2× \(\pi\)× r
The vertical angle is same as the central angle of the sector is 110°.
By using the given data and formula of arc length of the sector gives,
A = 110/360 × 2 × \(\pi\) × 7
By using the value of \(\pi\) = 22/7 in the above equation gives,
A = 11/36 × 2× 22/7 × 7
On simplifying gives,
A = 11/9 × 11
A = 121 / 9 = 13.44.
Therefore, the arc length of the sector is 13.44 cm.
Hence, the required vertical angle and angle of the sector is 110° and the arc length of the sector is 11 cm.

Let u:R+2→R be a strictly increasing C2 utility function. (a) Derive an expression for the slope of an indifference curve at an arbitrary consumption bundle (x0,y0)∈R++2. (b) Take a derivative of the expression in part (a) in order to compute the second-order derivative of the indifference curve. Demonstrate this second-order derivative is positive (i.e. the law of diminishing marginal rate of substitution holds) if u is quasiconcave on R+2
(a) The slope of an indifference curve at an arbitrary consumption bundle (x0, y0) is given by the negative ratio of the marginal utilities of x and y, i.e., -MUx/MUy.
(b) Taking the derivative of the expression in part (a) gives the second-order derivative of the indifference curve. If the utility function u is quasiconcave on R+2, this second-order derivative will be positive, demonstrating the law of diminishing marginal rate of substitution.
How can we express the slope of an indifference curve and its second-order derivative?In economics, an indifference curve represents the combinations of two goods (x and y) that provide the same level of utility or satisfaction to an individual.
The slope of an indifference curve measures the rate at which the individual is willing to substitute one good for another while remaining indifferent.
To derive an expression for the slope of an indifference curve at a given consumption bundle (x0, y0), we consider the marginal utilities of x (MUx) and y (MUy).
The slope is determined by the negative ratio of MUx to MUy, which indicates the relative change in x compared to y that maintains the same level of utility.
Taking the derivative of this expression provides the second-order derivative of the indifference curve. If the utility function u is quasiconcave on R+2, which means that indifference curves are convex, the second-order derivative will be positive.
This confirms the law of diminishing marginal rate of substitution, stating that as an individual consumes more of one good, they are willing to give up less of the other good to maintain the same level of satisfaction.

314. Of all the factoring methods covered in this chapter (GCF, grouping, undo FOIL, ‘ac’ method, special products) which is the easiest for you? Which is the hardest? Explain your answers.
Of all the factoring methods covered in this chapter, the easiest method for me is the GCF (Greatest Common Factor) method. This method involves finding the largest number that can divide all the terms in an expression evenly. It is relatively straightforward because it only requires identifying the common factors and then factoring them out.
On the other hand, the hardest method for me is the ‘ac’ method. This method is used to factor trinomials in the form of ax^2 + bx + c, where a, b, and c are coefficients. The ‘ac’ method involves finding two numbers that multiply to give ac (the product of a and c), and add up to give b. This method can be challenging because it requires trial and error to find the correct pair of numbers.
To summarize, the GCF method is the easiest because it involves finding common factors and factoring them out, while the ‘ac’ method is the hardest because it requires finding specific pairs of numbers through trial and error. It is important to practice and understand each method to become proficient in factoring.
