The measure of angle a is 15 degrees and this can be determined by using the properties of the isosceles triangle.

In geometry, interior angles are formed in two ways. One is inside a polygon, and the other is when parallel lines cut by a transversal. Angles are categorized into different types based on their measurements.

Given:

The following steps can be used in order to determine the measure of angle a:

Step 1 - According to the given data, it can be concluded that triangle PQR and triangle PSR are isosceles triangles.

Step 2 - Apply the sum of interior angle property on triangle PQR.

\(\angle\text{Q}+\angle\text{P}+\angle\text{R}=180\)

\(\angle\text{Q}+2\angle\text{R}=180\)

\(2\angle\text{R}=180-60\)

\(\angle\text{R}=60^\circ\)

Step 3 - Now, apply the sum of interior angle property on triangle PSR.

\(\angle\text{P}+\angle\text{S}+\angle\text{R}=180\)

\(\angle\text{S}+2\angle\text{R}=180\)

\(2\angle\text{R}=180-90\)

\(\angle\text{R}=45^\circ\)

Step 4 - Now, the measure of angle a is calculated as:

\(\angle\text{a}=60-45\)

\(\angle\text{a}=15\)

The measure of angle a is 15 degrees.

(a) The velocity of the object at time t = 7 is 16.6 m/s.

(b) The object reaches its maximum height after 9 seconds.

(c) The maximum height reached by the object is 391.05 m.

(d) The acceleration of the object is equal to the acceleration due to gravity, g = -9.8 m/s^2.

(e) The object hits the ground with a speed of 79.8 m/s and is in the air for 18 seconds. The total distance traveled by the object is 391.05 m.

Explanation:

(a) To find this velocity, we can use the equation v(t) = u + g*t, where u is the initial velocity of the object and g is the acceleration due to gravity. Substituting the given values of u = 88.2 m/s, g = -9.8 m/s^2, and t = 7, we get:

v(7) = 88.2 + (-9.8)*(7) = 16.6 m/s

Therefore, the velocity of the object at time t = 7 is 16.6 m/s.

(b) The time taken to reach the maximum height is found by equating the velocity equation to zero and solving for t.

0 = u + g*t_max

Rearranging the equation, we find:

t_max = -u/g

Substituting the given values of u = 88.2 m/s and g = -9.8 m/s^2, we can calculate the time taken to reach the maximum height:

t_max = -88.2/(-9.8) = 9 seconds

Hence, the object will reach its maximum height after 9 seconds.

(c) The maximum height reached by the object can be calculated using the position equation:

s(t) = -4.9t^2 + ut

At the maximum height, the velocity of the object becomes zero, so we use the time t_max = 9 seconds:

s(t_max) = -4.9*(9)^2 + 88.2*(9) = 391.05 m

Therefore, the maximum height reached by the object is 391.05 m.

(d) The acceleration of the object is equal to the acceleration due to gravity, g = -9.8 m/s^2, at any time.

(e) The time taken by the object to hit the ground is found by solving the position equation for t when the object's height becomes zero. Using the velocity equation, we can determine the velocity at the time of impact. The total distance traveled is the absolute difference between the initial and maximum height.

To determine the time taken by the object to hit the ground, we solve the position equation for t when s(t) = 0:

-4.9t^2 + 88.2t = 0

Simplifying, we find:

t(88.2 - 4.9*t) = 0

The solutions are t = 0 or t = 88.2/4.9 = 18 seconds.

Thus, the object is in the air for 18 seconds. Using the velocity equation to find the velocity at t = 18:

v(18) = 88.2 + (-9.8)*(18) = -79.8 m/s

Therefore, the object hits the ground with a speed of 79.8 m/s.

The total distance traveled by the object is given by the absolute value of the difference between the initial height and maximum height:

d = |s(t_max) - s(0)| = |391.05 - 0| = 391.05 m

Therefore, the total distance traveled by the object is 391.05 m.

Answer: 6.7

Step-by-step explanation:

The first number will be \(\frac{11}{2}\) and the second number will be \(-\frac{5}{4}\).

Let the first number be x and the second number be y.

According to the question,

Since seven times the first number plus six times the second number equals 31. So,

\(7x+6y=31.......(1)\)

Similarly,Three times the first number minus ten times the second number is 29.So,

\(3x-10y=29.......(2)\)

Multiplying equation (1) by 3 and equation (2) by 7, we get

\(21x+18y=93\)

\(21x-70y=203\)

Now subtracting both the equations we get,

\(88y=-110\)

\(y=-\dfrac{110}{88}\)

\(y=-\dfrac{5}{4}\)

putting the value of x in equation (1) we get,

\(7x+6\times-\dfrac{5}{4} =31\)

\(7x-\dfrac{15}{2}=31\\\)

\(7x=31+\dfrac{15}{2}\)

\(7x=\dfrac{77}{2}\)

\(x=\dfrac{11}{2}\)

Hence the first number is \(\frac{11}{2}\) and the second number is \(-\frac{5}{4}\).

Answer: Winston should invest $75,000 in the high-risk fund and $525,000 in the low-risk fund to achieve his retirement income goal.

Step-by-step explanation:

Let x be the amount of money invested in the high-risk fund, and y be the amount of money invested in the low-risk fund. We know that x + y = $600,000, since that is the total amount Winston plans to invest.

We also know that the high-risk investments should return 12% per year, and the low-risk investments should return 4% per year. Therefore, the total return on his investment will be:

0.12x + 0.04y

Winston wants a supplemental income of $30,000 per year. We can set up an equation for this as well:

0.12x + 0.04y = $30,000

We can use the equation x + y = $600,000 to solve for one of the variables in terms of the other. For example, we can solve for y as follows:

y = $600,000 - x

Substituting this expression for y into the equation for the total return, we get:

0.12x + 0.04($600,000 - x) = $30,000

Simplifying and solving for x, we get:

0.12x + $24,000 - 0.04x = $30,000

0.08x = $6,000

x = $75,000

Winston should invest $75,000 in the high-risk fund and $525,000 in the low-risk fund to achieve his retirement income goal.

The seventh term of the geometric sequence is -7/32. The nth term of the sequence, a1 is the first term, r is the common ratio, and n is the position of the term

To find the seventh term of a geometric sequence, we can use the formula:

\(an = a1 * r^(n-1),\)

where an represents the nth term of the sequence, a1 is the first term, r is the common ratio, and n is the position of the term we want to find.

In this case, we are given a2 = -7 and r = 1/2.

Using the formula, we can find a1 by substituting n = 2:

a2 = a1 * (1/2)^(2-1).

We know that a2 = -7, so we can rewrite the equation:

-7 = a1 * (1/2)^1,

-7 = a1 * (1/2).

Now, let's solve for a1:

a1 = -7 * (2/1),

a1 = -14.

We have found that the first term, a1, is equal to -14.

Now, we can find the seventh term, a7, by substituting n = 7 into the formula:

a7 = (-14) * (1/2)^(7-1),

a7 = (-14) * (1/2)^6,

a7 = (-14) * (1/64),

a7 = -14/64,

a7 = -7/32.

Therefore, the seventh term of the geometric sequence is -7/32.

Answer: The equation of the quadratic function is y = ax^2 + 8, where a is any non-zero constant.

Step-by-step explanation: The general form of a quadratic function is y = ax^2 + bx + c, where a, b, and c are constants. To find the equation of a quadratic function with a y-intercept at (0,8), we substitute x = 0 and y = 8 into the general equation to obtain:

8 = a(0)^2 + b(0) + c 8 = c

Therefore, c = 8, and the quadratic function is y = ax^2 + bx + 8.

Since we don't have any other condition to determine the values of a and b, any non-zero value of a can be chosen to satisfy the given condition. If a positive value is chosen for a, the graph of the function will open upwards, while choosing a negative value will make it open downwards. The value of b will alter the position of the vertex of the graph.

To find the probability of rolling six standard, six-sided dice and getting six distinct numbers, we need to calculate the total number of possible outcomes and the number of outcomes that satisfy the given condition.

Total Number of Outcomes:

The total number of possible outcomes when rolling six dice is 6^6, which is 46,656. Each die has six possible outcomes (1, 2, 3, 4, 5, or 6), and there are six dice being rolled.

Number of Outcomes with Six Distinct Numbers:

To get six distinct numbers when rolling six dice, each number must be different from the others. We can choose any six numbers from 1 to 6, and there are 6! (6 factorial) ways to arrange them on the six dice.

6! = 6 x 5 x 4 x 3 x 2 x 1 = 720

Probability of Getting Six Distinct Numbers:

To find the probability of rolling six standard, six-sided dice and getting six distinct numbers, we divide the number of outcomes with six distinct numbers by the total number of possible outcomes:

P(six distinct numbers) = number of outcomes with six distinct numbers / total number of outcomes

P(six distinct numbers) = 720 / 46,656

P(six distinct numbers) = 5 / 324

Therefore, the value of the probability is 5/324 or approximately 0.0154.
