The point slope form of the equation of the line through the given point with the given slope is y - 4 = -2(x + 1).

The equation in slope intercept form is y = -2x + 2.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁)

Where:

At data point (-1, 4), a linear equation of this line can be calculated in point-slope form as follows:

y - y₁ = m(x - x₁)

y - 4 = -2(x - (-1))

y - 4 = -2(x + 1)

Next, we would rewrite the equation in slope-intercept form as follows;

y - 4 = -2(x + 1)

y = -2x - 2 + 4

Yes, the function f(x) = 3 sin(2x) is periodic. The smallest positive period of this function is 2π/2 = π.

f(x) = 3 sin(2x) This is because the function is sinusoidal and the period of a sinusoidal function is 2π/n,

where n is the coefficient in front of the x (which in this case is 2). Thus, the period of f(x) = 3 sin(2x) is 2π/2 = π.

This means that the function will repeat itself after every π units. To verify this, we can plug in x = 0 and x = π into the equation and see that we get the same value, 3 sin(2(0)) = 3 sin(0) = 0 and 3 sin(2(π)) = 3 sin(2π) = 0, showing that the function repeats itself after every π units.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Let's call the number of members in the Senate "s".

The expression for the number of members in the House of Representatives is "h".

According to the problem, there are 35 more members in the House than four times the number of members in the Senate, so the expression for the number of members in the House is:

h = 4s + 35

If there are 100 members in the Senate, then we can substitute this value into the expression:

h = 4 × 100 + 35

h = 435

Compared to your regular wage without overtime, this would push your monthly budget up by $607.63.

In a budget, projected expenses are stated together with suggestions for how to fund them. A budget can show a surplus of resources for future use or a deficit where expenses are greater than income or other resources.

Surplus Budget, Balanced Budget, and Deficit Budget are 3 types of annual governmental budgets based on estimation. A balanced budget is one in which the revenues are larger than the expenses or equal to them. In the above link, you can read about the Highlights of the Union Budget for UPSC.

Let's calculate the regular earnings for 40 hours of work first:

Regular earnings = $11.75 x 40 hours = $470

Next, let's calculate the overtime earnings:

Overtime rate = $11.75 x 1.5 = $17.63

Overtime earnings = $17.63 x 20 hours = $352.60

Now let's add the regular earnings and overtime earnings to get the total gross pay for the month:

Total gross pay = $470 + $352.60 = $822.60

Now let's calculate the deductions:

FICA = $822.60 x 7.65% = $63.17

Federal tax withholding = $822.60 x 10.75% = $89.11

State tax withholding = $822.60 x 7.5% = $61.69

Total deductions = $63.17 + $89.11 + $61.69 = $214.97

So, the net pay for the month (total gross pay minus total deductions) would be:

Net pay = $822.60 - $214.97 = $607.63

Therefore, working 20 hours of overtime would increase your budget by $607.63.

The exact values of the remaining trigonometric functions of θ are:

sin(θ) = √(1/64)

cos(θ) = -8

tan(θ) = -8√(1/64)

csc(θ) = 1

cot(θ) = -√(1/64) / 8

Given that sec(θ) = -8 and sin(θ) > 0, we can find the exact values of the remaining trigonometric functions using the Pythagorean identity:

sec^2(θ) = 1/sin^2(θ)

Substituting the value of sec(θ), we have:

(-8)^2 = 1/sin^2(θ)

64 = 1/sin^2(θ)

sin^2(θ) = 1/64

sin(θ) = ±√(1/64)

Since sin(θ) > 0, we take the positive square root:

sin(θ) = √(1/64)

Next, we use the reciprocal identity for cosecant:

csc(θ) = 1/sin(θ)

Substituting the value of sin(θ), we have:

csc(θ) = 1/√(1/64) = 8√(1/64) = 8/√(64) = 8/8 = 1

Next, we use the reciprocal identity for cotangent:

cot(θ) = 1/tan(θ)

We can find the value of tan(θ) using the definition:

tan(θ) = sin(θ) / cos(θ)

Substituting the values of sin(θ) and cos(θ), we have:

tan(θ) = √(1/64) / (-8) = -√(1/64) / 8

Finally, we use the reciprocal identity for a tangent:

tan(θ) = 1/cot(θ)

Substituting the value of cot(θ), we have:

tan(θ) = -8√(1/64)

Therefore, the exact values of the remaining trigonometric functions of θ are:

sin(θ) = √(1/64)

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important.

It has members, just like a set does.

The length of the sequence is determined by the number of items.

You should be familiar with the following four main categories of sequences: arithmetic sequences, geometric sequences, quadratic sequences, and special sequences.

So, because the grain size of breccia and siltstone is the same, they should be assigned the same number.

- A cement-like substance holds angular shards of varying sizes together to form a rock called breccia.

- It can also be generated from volcanic ash or other materials but is often formed from angular shards of other rocks.

- A sedimentary rock called siltstone is made up of clay-sized particles and often has smaller grains than sandstone.

- A cementing substance holds rounded or sub-rounded grains and pebbles together to form the sedimentary rock known as a conglomerate.

- Sand-sized particles make up the sedimentary rock known as sandstone, which is often created from quartz grains.

- The last sedimentary rock is shale, which typically has a grain size lower than sandstone and is made up of clay-sized particles.

Answer:

Step-by-step explanation:

You can solve for a, b, and c by using a system of linear equations.

Starting with the first equation:

a + b + c = 90

You can isolate a by subtracting b and c:

a = 90 - b - c

Next, substitute the expression for a into the second equation:

12(90 - b - c) + 10b + 6c = 870

Expanding the equation:

1080 - 12b - 12c + 10b + 6c = 870

Combining like terms:

1070 - 2b + -6c = 870

Adding 2b and 6c to both sides:

1070 = 870 + 2b + 6c

Subtracting 870 from both sides:

200 = 2b + 6c

Dividing both sides by 2:

100 = b + 3c

Finally, subtracting 3c from both sides:

100 - 3c = b

To find c, substitute the expressions for a and b back into the first equation:

a + b + c = 90

90 - b - c + b + c = 90

90 - c = 90

-c = 0

Therefore, c = 0.

To find b, substitute c = 0 into the expression for b:

100 - 3c = b

100 = b

Therefore, b = 100.

Finally, to find a, substitute b = 100 and c = 0 into the expression for a:

a = 90 - b - c

a = 90 - 100 - 0

a = -10

Note that negative values for a, b, and c are possible, but not necessarily meaningful for this specific problem or context.

The solution is:

a = -10

b = 100

c = 0

The area of the right triangle is 80.5 square units.

The area of a triangle is described as the total region that is enclosed by the three sides of any particular triangle.

In the right triangle, one of the legs is equal to 7, as the side length of the square inscribed in it.

We will use the Pythagorean theorem to find the length of the other leg and the calculation is shown below:

a^2 + b^2 = c^2

7^2 + b^2 = 24^2

49 + b^2 = 576

b^2 = 527

b = √t(527) = 23

The model from the above summary is

y = 27.1349x^3 - 473.4406x^2 + 2829.3314x - 4381.6892

Approximate

y = 27.13x^3 - 473.44x^2 + 2829.33x - 4381.69

In the year 2001, we have

x = 11

So, we have

y = 27.13 * 11^3 - 473.44 * 11^2 + 2829.33 * 11 - 4381.69

Evaluate

y = 5565

The estimated the number of graduates in 2001 is 5565

The minimum value of [tex]$\|\mathbf{v}\|$[/tex] is zero.

The minimum value of [tex]$\|\mathbf{v}\|$[/tex] is zero, as it is the distance between the origin and a point on the line. To solve this problem, the formula [tex]$\|\mathbf{v}\| = \sqrt{x^2 + y^2}$[/tex] can be used, where x and y are the coordinates of the point on the line. Since the equation of the line is [tex]$\dbinom{10}{3} \dbinom{-2}{1}t$[/tex], the coordinates of the point on the line can be found by substituting [tex]$t = 0$: $x = 10 \cdot 0 - 2 \cdot 0 = 0$, and $y = 3 \cdot 0 + 1 \cdot 0 = 0$[/tex] . Substituting these values into the formula for [tex]$\|\mathbf{v}\|$ gives $\|\mathbf{v}\| = \sqrt{0^2 + 0^2} = 0$[/tex]. Therefore, the minimum value of [tex]$\|\mathbf{v}\|$[/tex] is zero.
