Answer:

One solution

Step-by-step explanation:

You do not have an addition or subtraction sign between -16x and 5y.  I am assuming that you mean addition.

Take -4x + y = 1 and multiply it all through by -4

16x - 4y = -4  Add this to the second equation

-16x + 5y = 8

          y = 4

Substitute 4 for y in either of the two original equations.

-4x + y = 1

-4x + 4 = 1   Subtract 4 from both sides

-4x + 4 - 4 = 1 - 4

-4x = -3  Divide both sides by -4

x = \(\frac{3}{4}\)

The solution is (\(\frac{3}{4}\), 4)

By using the rectangle, we proved that area of triangle is half the area of rectangle that is 1/2 (base×height).

To Prove:- Area of a triangle= 1/2 (base×height)

Diagonals of the rectangle divide it into two parts of equal areas.

Let  ABCD  be a rectangle.

In ΔABC and ΔADC,

                                         AC=AC

By Alternate Interior Angles:

                                    ∠BAC=∠CAD

                                    ∠BCA=∠CDA

Hence, ΔABC≅ΔACD

                               ∴ar(ΔABC) =ar(ΔACD)

Let ΔABC,

We draw a line AD perpendicular to BC, line EF parallel to BC passing through A and lines BE and CF , perpendicular to BC passing through B and C respectively.

In rectangle ADBE,

we get,

                     ar(ΔABE)=ar(ΔADB)

Similarly, in rectangle ADCF,

                     ar(ΔADC)=ar(ΔACF)

Now, area of rectangle BCFE, from axiom,

                               =(length)⋅(breadth)

                               =AB⋅BC

                              =AD⋅BC

Also,

ar(BCFE)

                                   =ar(ADBE) + ar(ADCF)

                                   =2⋅ar(ΔADC) + 2⋅ar(ΔADB)

                                   =2(ar(ΔADC) + ar(ΔADC)

                                   =2(ar(ΔABC))

From (1) and (2),

                                   2(ar(ΔABC)) = AD⋅BC

                                    ar(ΔABC) = 1/2AD⋅BC

                                   ar(ΔABC) = 1/2(base)⋅(height)

Without using a calculator, the trigonometric expressions simplify to:

1. sin^(-1)(sin(θ/6)) = θ/6

2. cos^(-1)(cos(5/4)) = 5/4

3. tan^(-1)(tan(5/6)) = 5/6.

To compute the trigonometric expressions without using a calculator, we can make use of the properties and relationships between trigonometric functions.

1. sin^(-1)(sin(θ/6)):

Since sin^(-1)(sin(x)) = x for -π/2 ≤ x ≤ π/2, we have sin^(-1)(sin(θ/6)) = θ/6.

2. cos^(-1)(cos(5/4)):

Similarly, cos^(-1)(cos(x)) = x for 0 ≤ x ≤ π. Therefore, cos^(-1)(cos(5/4)) = 5/4.

3. tan^(-1)(tan(5/6)):

tan^(-1)(tan(x)) = x for -π/2 < x < π/2. Thus, tan^(-1)(tan(5/6)) = 5/6.

Hence, without using a calculator, we find that:

sin^(-1)(sin(θ/6)) = θ/6,

cos^(-1)(cos(5/4)) = 5/4,

tan^(-1)(tan(5/6)) = 5/6.

Yes, both 2 and x are polynomials. A polynomial is any expression that consists of variables, coefficients, and non-negative integer exponents.

A variable is a named storage location used to store a value that can be changed during the execution of a program. Variables are typically used to store values that are entered by a user or used to store the results of calculations or operations. Variables can be declared with different data types, such as strings, integers, or decimals, and can be given a name to be used when referring to the value stored in the variable.

That can be written in the form \(\mathrm a_nx^n + a_n-1x^n-1 + ... + a_2x^2 + a_1x + a_0\).

The values of displacement, velocity, and acceleration are 2.68 m, 2.24 m/s, and -18.07 m/s2 respectively.

We know that the amplitude, A = 2 + T; the angular velocity, ω = 4 + U rad/s; and time, t = 1s. Here, the value of T = 1 and the value of U = 4 (as mentioned in the question).

Harmonic motion is a motion that repeats itself after a certain period of time.

Harmonic motion is caused by the restoring force that is proportional to the displacement from equilibrium.

The three types of harmonic motions are as follows: Free harmonic motion: When an object is set to oscillate, and there is no external force acting on it, the motion is known as free harmonic motion.

Damped harmonic motion: When an external force is acting on a system, and that force opposes the system's motion, it is called damped harmonic motion.

Forced harmonic motion: When an external periodic force is applied to a system, it is known as forced harmonic motion.Vectorial formVibrations of harmonic motion can be represented in a vectorial form.

A simple harmonic motion is a projection of uniform circular motion in a straight line.

The displacement, velocity, and acceleration of a particle in simple harmonic motion are all vector quantities, and their magnitudes and directions can be determined using a coordinate system.

Let's now calculate the values of displacement, velocity, and acceleration.

Displacement, s = A sin (ωt)

Here, A = 2 + 1 = 3 (since T = 1)and, ω = 4 + 4 = 8 (since U = 4)

So, s = 3 sin (8 x 1) = 2.68 m (approx)

Velocity, v = Aω cos(ωt)

Here, v = 3 x 8 cos (8 x 1) = 2.24 m/s (approx)

Acceleration, a = -Aω2 sin(ωt)

Here, a = -3 x 82 sin(8 x 1) = -18.07 m/s2 (approx)

Thus, the values of displacement, velocity, and acceleration are 2.68 m, 2.24 m/s, and -18.07 m/s2 respectively.

False. The expected cell frequency in statistical analysis, specifically in the context of contingency tables and chi-square tests, is not based on the researcher's opinion. Instead, it is determined through mathematical calculations and statistical assumptions.

In contingency tables, the expected cell frequency refers to the expected number of observations that would fall into a particular cell if the null hypothesis of independence is true (i.e., if there is no relationship between the variables being studied). The expected cell frequency is calculated based on the marginal totals (row totals and column totals) and the overall sample size.

The expected cell frequency is computed using statistical formulas and is not influenced by the researcher's opinion or subjective judgment. It is a crucial component in determining whether the observed frequencies in the cells significantly deviate from what would be expected under the null hypothesis.

By comparing the observed cell frequencies with the expected cell frequencies, statistical tests like the chi-square test can assess the association or independence between categorical variables in a data set.

Thus, the statement "the expected cell frequency is based on the researcher's opinion" is false. The expected cell frequency is derived through statistical calculations and is not subject to the researcher's subjective input.

c. The graph has no​ x-intercepts.

Step-by-step explanation:

because it will never touch the x axis

A quadratic function is represented as: \(\mathbf{f(x) = ax^2 + bx + c}\)

The conclusion from \(\mathbf{b^2 - 4ac > 0}\) is that, the graph has two distinct x-intercepts

There are three possible roots of a quadratic function

When \(\mathbf{b^2 - 4ac > 0}\), it means that:

The function has distinct real roots

In other words, the function has 2 different values of x

This implies that,

The function crosses the x-axis two times

When the function cross the x-axis, it means that the function has an x-intercept

The voltage across the capacitor at t=0+ is 4 volts (c \(V_c(t=0+)\) )is 4V). As time approaches infinity, the voltage across the capacitor becomes 6 volts ( \(V_c( t \to\infty)\) )is 6V). The current through the capacitor at t=0+ is -2 milliamperes ( \(i_c(t=0+)\) )is -2mA).

At t=0+, the switch opens and the circuit transitions into a new steady state. Initially, the capacitor is fully charged to 4V, so \(V_c(t=0+)\)is 4V. In the new steady state, the capacitor is connected to a series combination of R1, R2, R3, and R4. Since R1 and R2 are in series, their total resistance is 3kΩ. Thus, the time constant of the circuit is given by τ = (R1+R2+R3+R4)C = 6kΩ * 1μF = 6ms.

To determine\(V_c( t \to\infty)\) , we consider the steady state behavior of the circuit. In steady state, the capacitor acts as an open circuit. Therefore, the current flowing through R4 is zero, and the voltage drop across R4 is also zero. Thus, \(V_c( t \to\infty)\) is equal to the voltage drop across R3, which is 6V.

At t=0+, the current through R1, R2, and R3 will be the same as the current through the capacitor, ( \(i_c(t=0+)\) ). Applying Kirchhoff's current law at the node connecting R1, R2, R3, and the capacitor, we find that ( \(i_c(t=0+)\) )= I - (Vc(t=0+)/R1+R2+R3) = 4mA - (4V/3kΩ) = -2mA.

In summary, \(V_c(t=0+)\) is 4V, \(V_c( t \to\infty)\) is 6V, and \(i_c(t=0+)\)is -2mA.

P(X ≤ 10) represents the probability that up to 10 apples in a basket of 100 are too small to sell.

To find the proportion of apples from the 2006 crop that were too small to sell, we need to calculate the probability that an apple weighs less than 130 grams. We can do this by using the standard normal distribution.

Proportion of apples too small to sell:

Let X be the weight of an apple from the crop. We are given that X follows a normal distribution with a mean of 173 grams and a standard deviation of 34 grams.

To find the proportion of apples weighing less than 130 grams, we need to calculate the cumulative distribution function (CDF) of the standard normal distribution up to the z-score corresponding to 130 grams.

First, we need to standardize the value of 130 grams using the formula:

z = (X - μ) / σ

where X is the value (130 grams), μ is the mean (173 grams), and σ is the standard deviation (34 grams).

z = (130 - 173) / 34 = -43 / 34 ≈ -1.2647

Using a standard normal distribution table or a calculator, we can find the CDF corresponding to this z-score. The CDF represents the proportion of values less than -1.2647 in the standard normal distribution.

Let P(Z < -1.2647) = p

The proportion of apples from the 2006 crop that were too small to sell is approximately p.

Probability of up to 10 apples too small to sell in a basket of 100 apples:

We can use the binomial distribution to calculate the probability of up to 10 apples being too small to sell in a basket of 100 apples.

Let X be the number of apples too small to sell in a basket of 100. The probability of a single apple being too small is p, as calculated in the previous step.

Using the binomial distribution formula, we can calculate the probability of X being less than or equal to 10:

P(X ≤ 10) = Σ (n choose x) * p^x * (1 - p)^(n - x)

where n is the number of trials (100), x is the number of successes (up to 10), and p is the probability of success (as calculated earlier).

This involves summing the probabilities for x = 0, 1, 2, ..., 10.

By calculating this probability, we can determine the likelihood of encountering up to 10 undersized apples in a picker's basket of 100 apples.
