Answer:

[tex]\dfrac{223}{64}=3.484375[/tex]

Step-by-step explanation:

The Riemann sum is a method by which we can approximate the area under a curve using a series of rectangles.

The Lower Riemann Sum uses the minimum height of the rectangle on each subinterval.  

As the Lower Riemann Sum is entirely below the curve, it is an underestimation of the area under the curve.

The number of partitions is the number of rectangles used.  

Partitions can be of equal length or not of equal length.

Given:

The given partition divides the interval [0, 1] into 3 subintervals:

To calculate the areas of the rectangles, multiply the width of each rectangle by its height.

The width is the difference between the x-values of each subinterval.

The height is the minimum value of the function across the subinterval. For the given function, this is the value of the function for the right side of the subinterval.

First rectangle [0, 1/2]:

[tex]\begin{aligned}\implies \left(\dfrac{1}{2}-0\right) \cdot f\left(\dfrac{1}{2}\right)&=\dfrac{1}{2} \cdot \left(4-\left(\dfrac{1}{2}\right)^2\right)\\\\&=\dfrac{1}{2} \cdot \dfrac{15}{4}\\\\&=\dfrac{15}{8}\end{aligned}[/tex]

Second rectangle [1/2, 3/4]:

[tex]\begin{aligned}\implies \left(\dfrac{3}{4}-\dfrac{1}{2}\right) \cdot f\left(\dfrac{3}{4}\right)&=\dfrac{1}{4} \cdot \left(4-\left(\dfrac{3}{4}\right)^2\right)\\\\&=\dfrac{1}{4} \cdot \dfrac{55}{16}\\\\&=\dfrac{55}{64}\end{aligned}[/tex]

Third rectangle [3/4, 1]:

[tex]\begin{aligned}\implies \left(1-\dfrac{3}{4}\right) \cdot f\left(1\right)&=\dfrac{1}{4} \cdot \left(4-\left(1\right)^2\right)\\\\&=\dfrac{1}{4} \cdot 3\\\\&=\dfrac{3}{4}\end{aligned}[/tex]

Therefore, the Lower Reimann Sum for the given function over the given interval and partitions is the sum of the area of the rectangles:

[tex]\implies \dfrac{15}{8}+\dfrac{55}{64}+\dfrac{3}{4}=\dfrac{223}{64}=3.484375[/tex]

The answer is 75.96 degree.

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given here: The perpendicular = 2 and base=8

 Thus tan ∅ = 2/8

           tan ∅=1/4

                 ∅=tan⁻¹(1/4)

                   = 14.03

Therefore the required angle is 180-(90+14.03)=  75.96°

Hence, The answer is 75.96 degree.

[tex]\rule[225]{225}{2}[/tex]

Answer: X = 25

Step-by-step explanation: We can use the Law of Cosines to solve for the remaining side of the triangle, which we'll call "x".

The Law of Cosines states that:

c^2 = a^2 + b^2 - 2ab * cos(C)

In this triangle, we are trying to find side "x" (c) so we can use the following equation:

x^2 = 20^2 + 17^2 - 2(20)(17)cos(H)

Now we can substitute the known values into the equation:

x^2 = 400 + 289 - 680cos(H)

Now we can solve for x by taking the square root of both sides:

x = sqrt(400 + 289 - 680cos(H))

= sqrt(689 - 680cos(H))

= sqrt(9 + 289cos(H))

Alternatively, we can use Law of Sines to solve for side x.

The Law of Sines states that a/sin(A) = b/sin(B) = c/sin(C)

Knowing all the angles in the triangle we can use the following equation

x/sin(K) = 20/sin(P) = 17/sin(H)

Now we can substitute the known values into the equation

x = (20*17)/sin(H)

In both case we get x = 25.

The probability of the first number being divided by the second number is greater than zero is 1/2.

Probability is a way to gauge how likely something is to happen. According to the probability formula, the likelihood that an event will occur is equal to the proportion of positive outcomes to all outcomes. Probability that an event will occur P(E) is equal to the ratio of favourable outcomes to total outcomes. Because the favourable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1. Additionally, the proportion of positive outcomes cannot be negative.

Given four tiles in a bag with numbers -2, -1, 1, 2

one tile selected at random the probability is 1/4

tile return to bag and another tile selected,

the probability of the second tile is 1/4

total outcome for both is 4 x 4 = 16

the ratio of both numbers should be positive

outcomes are (-2, -1)(-2, -2)(-1, -1)(-1, -2)(2, 1)(2, 2)(1, 1)(1, 2)

favourable outcome are 8

probability is 8/16 = 1/2

Hence the probability is 1/2

The force of the thrust loaded and supported as 12KN

By taking into account the equilibrium of the entire truss, it is possible to predict the reaction at the supports. Only the vertical component of the reaction at the ends A needs to be taken into account since both external loads are vertical. Given that the angle of the triangle AEC is 90 degrees, it has a right angle.

AE = AC cos 60º = 5 X 0.5 = 2.5m

CE = AC sin60º = 5 X 0.866 = 4.33m

Due to the fact that triangle ABE is an equilateral triangle,

AB = BC = AE = 2.5m

A right-angle triangle with an angle, the triangle BDC is once again

BDC = 90º

Also, BC = AC – AB = 5 – 2.5 = 2.5m BD = BC cos 60º = 2.5 X 0.5 = 1.25m

path of action of 12 KN force away from joint A,

AG = AB + BG

The probability that both numbers generated the number '5' is 1/100

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

The probability is expressed as : sample space/ total outcome

Two number generators can generate number from 1 to 10. This means that the total outcome is 10.

The number 5 has a sample space of 1 in the generated numbers.

Therefore the probability to generate 5 in the first machine = 1/10

The probability to generate 5 in the second machine = 1/10

The probability to generate 5 in both machines = 1/10 × 1/10 = 1/100.

The term "rate of change" (ROC) describes the rate at which something changes over time. Thus, it is not the amount of individual changes themselves but rather the acceleration or deceleration of changes.

When something changes over time, it does so at a certain rate, or ROC. Therefore, rather than the size of each change individually, it is the rate of change—or, more specifically, its acceleration or deceleration. Rate of change is a concept in finance that is used to comprehend price returns and pinpoint trends' momentum.

A ratio is used to express the rate of change, which contrasts the values of the y and x variables. The slope of the line represents the rate of change if it is linear, constant, and so on. Positive, negative, zero, or undefinable slopes are all possible for lines.

The price of an adult ticket is $14 and the price of a children's ticket is $8.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Let x be the price of an adult's ticket and y be the price of a children's ticket.

One family bought 1 adult ticket and 3 children's tickets for a total of $38.

x + 3y = 38

Another family bought 2 adult tickets and 4 children's tickets for a total of $60.

2x + 4y = 60

We have two linear equations in two variables here.

x + 3y = 38

2x + 4y = 60

Multiplying the first equation throughout by 2, we get,

2x + 6y = 76

Subtracting the second equation 2x + 4y = 60 from the multiplied first equation 2x + 6y = 76, we get,

2x + 6y - (2x + 4y) = 76 - 60

2y = 16

y = 8

x + 3y = 38 ⇒ x = 38 - 24 = 14
