Step-by-step explanation:

we have that

[tex]m<R=(8x-1)\°[/tex]

[tex]m<Q=(9x-6)\°[/tex]

[tex]m<R+m<Q=180\°[/tex] ------> by supplementary angles

Substitute the values and solve for x

[tex]8x-1+9x-6=180\°[/tex]

[tex]17x-7=180\°[/tex]

[tex]17x=187\°[/tex]

[tex]x=11\°[/tex]

Find the value of angle R

[tex]m<R=(8*11-1)\°=87\°[/tex]

Find the value of angle Q

[tex]m<Q=(9*11-6)\°=93\°[/tex]

The measure of angle Q and R can be obtained by supplementary angle. The supplementary angle is defined as the addition of two angle is [tex]180^{\circ}[/tex].

The angle Q is [tex]93^{\circ}[/tex] and angle R is [tex]87^{\circ}[/tex].

Given:

The equation for unknown angle is,

[tex]8x -1 + 9x - 6 = 180[/tex]

The supplementary angle is,

[tex]\angle R+\angle Q=180^{\circ}[/tex]

Compare the above equation.

[tex]\angle R=(8x-1)^{\circ}\\\angle Q=(9x-6)^{\circ}[/tex]

Solve the given expression.

[tex]\begin{aligned}8x -1 + 9x -6 &= 180\\ 17x - 7 &= 180 \\17x &= 187 \\x&=11\\\end[/tex]

Calculate the Angle R.

[tex]\angle R=(8\times 11-1)\\\angle R=87^{\circ}[/tex]

Calculate the Angle Q.

[tex]\angle Q=(9\times 11-6)\\\angle Q=93^{\circ}[/tex]

Thus, the angle Q is [tex]93^{\circ}[/tex] and angle R is [tex]87^{\circ}[/tex].

To find g'(a), take the derivative of G(x) with respect to x. Substitute x-values into g'(a) to find slope of tangent line. Use slope and point to write equation of tangent line.

To find g'(a), we need to take the derivative of G(x) with respect to x. The derivative of G(x) is the slope of the tangent line to the curve at any given point. In this case, G(x) = x^2 - 7x + 7, so g'(a) = 2a - 7.

For the point (0, 7), we substitute x = 0 into g'(a) to find the slope of the tangent line at that point:

Therefore, the equation of the tangent line at (0, 7) is y = -7x + 7.

Similarly, for the point (6, 1), we substitute x = 6 into g'(a) to find the slope of the tangent line at that point:

Therefore, the equation of the tangent line at (6, 1) is y = 5x - 29.

Final answer:

The exact value of tan(30°) is found using the sine and cosine values of 30°, resulting in tan(30°) being approximately 0.577.

Explanation:

To find the exact value of tan(30°), we look at the relationship between the sides of a 30-60-90 triangle or use the definitions of sine and cosine. The sine of 30° (sin(30°)) is 0.500, and the cosine of 30° (cos(30°)) is 0.866. The tangent is the ratio of sine to cosine, so:

tan(30°) = sin(30°) / cos(30°) = 0.500 / 0.866

When you calculate that ratio, you get tan(30°) = approximately 0.577, which is the exact value for tangent of 30 degrees.

Final answer:

To find the total number of games in a 64-team knockout soccer tournament, we observe that the number of games played in each round is half of the previous round, starting from 32 games in round one. By summing the games from all rounds, we determine that a total of 63 games are played in the tournament.

Explanation:

To calculate the total number of games played in a knockout soccer tournament with 64 teams, we can notice that in each round, half of the teams get eliminated and thus the number of games played is halved. Starting with the first round where 32 games are played, we can sum the total number of games for each subsequent round until we reach the final game.

Here's the pattern of games played per round until the final:

The total number of games played in the tournament is the sum of the games played in each round:

32 + 16 + 8 + 4 + 2 + 1 = 63 games

Therefore, the total number of games played in the regional soccer tournament is 63 games.

The equation of line which is perpendicular to the given line and has a given point is required.

The equation of the line is [tex]y=\dfrac{1}{2}x+2[/tex].

The given line is

The equation of the line passing through point P(2,3) that is perpendicular to the line y-4=-2(x+3) is y = (1/2)x + 2.

To find the equation of the line passing through point P(2,3) that is perpendicular to the line y-4=-2(x+3), we need to find the slope of the perpendicular line first. The given line has a slope of -2. The slope of the perpendicular line will be the negative reciprocal of -2, which is 1/2.

Now that we have the slope, we can use the point-slope form of the equation of a line. The equation is given by y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope. Plugging in the values, we have y - 3 = (1/2)(x - 2).

This simplifies to y - 3 = (1/2)x - 1, and further simplifies to y = (1/2)x + 2.

Compound interest is different from simple interest. In compound Interest, interest amount will vary each year. Interest is calculated first on the principal amount and then interest is the accumulated interest on the previous year.

Compound interest compounded continuously means interest is accumulating not within a month or year, but continuously.

If compound interest is compounded continuously, then the formula for calculating the final amount is,

A = P e^rt

where A is the final amount, P is the principal amount, r is the rate of interest and t is the time period.

Here, P = $2,000

r = 5% = 5/100 = 0.05

t = 20 years

A = 2000 × e^(0.05 × 20)

   = 2000 × e^1

   = 2000e

The value of e = 2.7182818..

A = 2000 × 2.7182818

   = 5436.5636 ≈ 5436.56

Hence by the amount deposited by philanthropist, if the interest is compounded continuously, the college will receive $5436.56.

Answer: y = -(1/2)x

Step-by-step explanation: Direct variation of y with x means that:

y = k*x

where k is a real constant.

We know that when y = -4, the value of x is 8. So we can replace these values in the equation and find the value of k.

-4 = k*8

now we divide by 8 into both sides:

-4/8 = k*8/8 = k

-1/2 = k

So the equation is:

y = -(1/2)x

The equation is k = y/x and the value of k is  -1/2

The equation that can be used to represent direct proportion is y = kx

Where:

When k is made the subject of the formula, the equation becomes:

k = y/x

k = -4/8 = -1/2
