Answer: The trigonometric identity for the tangent of a sum of angles can be used to simplify the expression:

tan (480° + 300°) = (tan 480° + tan 300°) / (1 - tan 480° tan 300°)

Using the identity for the tangent of half an angle, the tangent of 480° can be expressed as follows:

tan 480° = tan (450° + 30°) = (tan 450° + tan 30°) / (1 - tan 450° tan 30°) = (1 + tan 30°) / (1 - tan 30°) = (1 + √3/3) / (1 - √3/3) = (1 + √3) / (√3 - 1)

Using the identity for the sine and cosine of a multiple of 30°, the tangent of 300° can be expressed as follows:

tan 300° = tan (30° * 10) = tan 30° / (1 - tan 30°) = √3 / (1 - √3) = √3 / (-1 - √3)

Plugging these values back into the expression for tan (480° + 300°), we get:

tan (480° + 300°) = (tan 480° + tan 300°) / (1 - tan 480° tan 300°) = ( (1 + √3) / (√3 - 1) + √3 / (-1 - √3) ) / (1 - (1 + √3) / (√3 - 1) * √3 / (-1 - √3) )

Expanding the denominator and simplifying, we get:

tan (480° + 300°) = ( (1 + √3) / (√3 - 1) + √3 / (-1 - √3) ) / ( (√3 - 1) / (-1 - √3) - (1 + √3) / (-1 - √3) )

Using the identity for the sine and cosine of a sum of angles, the sine and cosine of 480° + 300° can be expressed as follows:

sin (480° + 300°) = sin 480° cos 300° + cos 480° sin 300°

Finally, using the identity for the tangent of an angle in terms of sine and cosine, we get:

tan (480° + 300°) = sin (480° + 300°) / cos (480° + 300°) = sin 780° / cos 780°

The other trigonometric functions in the expression can be simplified using similar techniques, but the final result may be complex. However, it can be verified that the expression is equal to 3/2 by using a calculator or numerical methods.

Step-by-step explanation:

The derivative of the function y = tan⁻¹ x which is expressed in terms of x will be 1 / (1 + x²).

The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.

The function is given below.

x = tan y

Get the equation for y, then we have

x = tan y

y = tan⁻¹ x

Differentiate the function with reprect to 'x', then we have

The amplitude of subsequent oscillations is 0.093 m.

The spring stiffness is quantified by the spring constant, or k. For various springs and materials, it varies. The stiffer the spring is and the harder it is to stretch, the bigger the spring constant.

Given that,

Mass of a block, m = 1.2 kg

Spring constant of the spring, k = 14.0 N/m

While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 32.0 cm/s or 0.32 m/s

We need to find the amplitude of the subsequent oscillations.

We can use the conservation of energy here. Initially, the kinetic energy of the block is maximum and then it gets converted to the potential energy of the spring.

Mathematically,

[tex]\frac{1}{2} mv^2=\frac{1}{2}kv^2[/tex]

A is the amplitude of subsequent oscillations.

[tex]A=\sqrt{(\frac{mv^2}{k} )} \\\\A=\sqrt{\frac{(1.2)(0.32)^2}{14} } \\\\A=0.093m[/tex]

So, the amplitude of subsequent oscillations is 0.093 m.

Step-by-step explanation:

a probability is always the ratio

desired cases / totally possible cases.

if 2 non-overlapping events should occur, the probability of both events happening is the product of both individual probabilities.

e.g. the probability to roll two 6 with 2 dice (or in 2 consecutive rolls with 1 die) is 1/6 × 1/6 = 1/36

if 1 of 2 possible non-overlapping events should occur, the probability of one of the events happening is the sum of the individual probabilities.

e.g. the probability to roll a 1 or a 2 with a die is

1/6 + 1/6 = 2/6 = 1/3

both students are dual-enrolled.

in our case, for the first selection we have the totally possible cases of 27.

the desired cases (dual-enrolled) are 17.

so, the probabilty to select a dual-enrolled student is

17/27

for the second selection (without replacement of the first pull) the totally possible cases are now 26 (because we pulled one student from the general pool of candidates in the first selection).

the desired cases are now 16 (because for our case we pulled a dual-enrolled student from the general pool).

the probabilty to select a dual-enrolled student in the second selection is

16/26 = 8/13

the overall probability to select two dual-enrolled students in 2 selections is

17/27 × 8/13 = 136/351 = 0.387464387... ≈ 0.387

the first student is dual-enrolled, the second is not.

for the first selection the totally possible cases are 27.

the desired cases are again 17.

the probability of the first dejection is again

17/27

for the second selection the totally possible cases are 26 (see above).

the desired cases are still 10.

the probably for this second selection is

10/26 = 5/13

the overall probability to select first a dual-enrolled student and then a not-dual-enrolled student is

17/27 × 5/13 = 85/351 = 0.242165242... ≈ 0.242

Answer:

Fourth option: √65/4

Step-by-step explanation:

Since the angles are similar, each of the angles of ΔEFG must be equal to each of the corresponding angles of ΔHIJ

Specifically, m ∠J in ΔHIJ = m∠G in Δ EFG

Let's first find ∠G

Since EFG is a right triangle,

tan(G) = EF/FG = √65/4

tan J must be the same as tan G  = √65/4

This is the fourth  option

The value of tanJ is in the right angled triangle HIJ√65 / 4

An equation is an expression that contains numbers and variables linked together by mathematical operations of addition, subtraction, multiplication, division and exponents. An equation can either  be linear, quadratic, cubic, depending of the degree of the variable.

Two triangles are similar if their corresponding angles are equal to each other.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

p = 477/1000 = 0.477

p = 0.48

n = 1000

Now,

The test statistic for a hypothesis test for a proportion is given by:

z = (pi - p) / sqrt(p * (1 - p) / n)

where p is the sample proportion, p is the hypothesized proportion under the null hypothesis, n is the sample size, and sqrt is the square root function.

Substituting these values into the formula, we get:

z = (0.477 - 0.48) / sqrt(0.48 * 0.52 / 1000) ≈ -0.61

We find that the area to the left of z = -0.61 is approximately 0.2709 This means that the probability of getting a test statistic as extreme or more extreme than -0.61, assuming the null hypothesis is true, is 0.2709

Therefore, by probability the answer will be 0.2709

Check the picture below.

Answer:

Step-by-step explanation:

The inequality 5x+12y ≤ 30 represents a shaded region in the xy-plane that includes all the points that satisfy the inequality. To graph this inequality, we can first graph the equation 5x+12y = 30, which is the boundary line of the shaded region.

To graph the boundary line, we can find its x- and y-intercepts:

x-intercept: Set y = 0 and solve for x: 5x + 12(0) = 30, which gives x = 6.

y-intercept: Set x = 0 and solve for y: 5(0) + 12y = 30, which gives y = 2.5.

So the boundary line passes through the points (6, 0) and (0, 2.5).

Next, we can determine which side of the boundary line to shade. One way to do this is to pick a test point that is not on the line and plug it into the inequality. For example, the point (0,0) is a convenient test point. Plugging in x=0 and y=0 into the inequality, we get:

5(0) + 12(0) ≤ 30

which simplifies to 0 ≤ 30. Since this is true, we know that the region containing the point (0,0) is part of the shaded region, and therefore the shaded region is the one that contains the origin.

Putting it all together, we can graph the inequality by drawing the line 5x+12y = 30 and shading the region below the line, as shown in the figure below:

 3  |       x

    |      /

The percent change of an object is the ratio of its final value to its initial value.

The percentage of an item's final value versus its starting value is its percent change. By dividing the difference in data by the starting value, you can get the percent change.

"Rate" simply refers to the quantity divided by another number, typically 100, 1,000, or another multiple of 10. A rate per 100 is known as a percentage.

Percentage Change is the difference that results from deducting the old value from the new value, dividing by the old value, and multiplying the result by 100 to represent it as a percentage. In most cases, multiplying a fraction by 100 results in a percent conversion.

Using the Divergence Theorem, we get the flux of F across the closed surface S is π/2 (27√2 - 27).

To apply the Divergence Theorem, we will first compute the divergence of F as follows -

div(F) = ∂Fx/∂x + ∂Fy/∂y + ∂Fz/∂z

= 1 + 1 + 1

= 3

Now we will calculate the flux of F across the closed surface S that completely surrounds T. By the Divergence Theorem, this is equal to the triple integral of the divergence of F over the region T and is given by -

∫∫S F•n dS = ∭T div(F) dV

We can describe the region T using cylindrical coordinates:

0 ≤ r ≤ 2

-π/2 ≤ θ ≤ π/2

0 ≤ z ≤ √(9 - r sin θ)

The bounds on r and θ come from the fact that the half cylinder is contained within the plane x = 2, and the plane y = ±3. The bounds on z come from the equation of the half cylinder.

Now we can write the triple integral as follows -

∭T div(F) dV = ∫0^2 ∫-π/2^π/2 ∫0^√(9 - r sin θ) 3 r dz dθ dr

Evaluating this integral, we get,

∭T div(F) dV = π/2 (27√2 - 27)

Therefore, the flux of F across the closed surface S is π/2 (27√2 - 27).
