Final answer:

To calculate the interest after 6 months with a principal of $750,000 and an annual interest rate of 5%, you need to convert the annual rate to a monthly rate and then use the formula Interest = Principal × Rate × Time. The interest after 6 months is $1,562.50.

Explanation:

To calculate the interest after 6 months, we can use the formula:

Interest = Principal × Rate × Time

Here, the principal is $750,000, the annual interest rate is 5%, and the time is 6 months.

First, we need to convert the annual interest rate to a monthly rate:

Monthly interest rate = Annual interest rate / 12

Monthly interest rate = 5% / 12 = 0.4167%

Now, we can calculate the interest:

Interest = $750,000 × 0.4167% × 6/12

Interest = $1,562.50

The definitions of the labels are:

Since RQU is the sum of RQS, SQT and TQU, it measures 19+71+18 degrees, i.e. 108 degrees, and thus it's obtuse

Similarly, SQU is the sum of SQT and TQU, so it measures 71+18 = 89 degrees, so it's acute.

Finally, RQT is the sum of RQS and SQT, so it measures 19+71=90 degrees, and it's a right angle.

obtuse, acute and right

∠RQU = 19° + 71° +18° = 108° ⇒ obtuse angle

∠SQU = 71° + 18° = 89° ⇒ acute

∠RQT = 19° + 71° = 90° ⇒ right

GIVEN: y = -5/6x + 6

slope of given line = -5/6

--> Because the line you are trying to find is perpendicular to the given line, you must find the opposite reciprocal of the slope

opposite reciprocal of the slope = 6/5

You need to find what "b" is for your equation

Plug "b" back into the slope-intercept form along with your equation's slope

y = mx + b

(if your teacher doesn't want any decimals, then write: y = 6/5x + 89/5)

The equation of the line that is perpendicular to y=-5/6x+6 and cross through the point (-9,7) is y = 6/5x + 29.8, found by using the slope-intercept form and the concept of negative reciprocal slopes.

To find the equation of the line that is perpendicular to y=-5/6x+6 and crossing through the point (-9,7), we first need to find the slope of that line. We can determine that by knowing that the slopes of perpendicular lines are negative reciprocals of each other. So, if the slope of given line is -5/6, the slope of the line perpendicular to it will be the negative reciprocal, which is 6/5.

Now we have a point (-9,7) and a slope (6/5) and can use the slope-intercept form of a line to write the equation of a line.

We use the formula y = mx + b:

 Where 'y' and 'x' are coordinates of a point on the line, 'm' is the slope, and 'b' is the y-intercept. We know 'm', 'y' and 'x', so we can solve for 'b'. Substituting, we get: 7 = (6/5)(-9) + b, which simplifies to b = 29.8.

The equation of the line in slope-intercept form is: y = 6/5x + 29.8

Final answer:

The equation that demonstrates the additive inverse property is B. 6 + (-6) = 0, where 6 and -6 are additive inverses of each other.

Explanation:

The equation that illustrates the additive inverse property is B. 6 + (-6) = 0. The additive inverse property states that for any number 'a', there is a number '-a' such that 'a' plus '-a' equals zero. This is because adding a number to its additive inverse (which is the negative of the number) will result in zero.

Examples demonstrating the additive inverse include subtracting a positive number and changing its sign before operating the addition, for instance, 5-(+3) results in 5-3, which equals 2. Conversely, if you subtract a negative number, like subtracting -6 from 2, you would perform 2-(-6) which equals 2+6, resulting in 8.

It will take 120 minutes to fill up

The pump will take 120 minutes to fill the tank.

To answer the question of how many minutes it will take to fill an 800-unit tank that is already 1/4 full using a pump that can supply 5 units of water per minute, we must first determine the amount of water needed to fill the tank completely.

Since the tank is 1/4 full, it already contains 800 units * 1/4 = 200 units of water. Therefore, the remaining volume to fill is 800 units - 200 units = 600 units. Next, we divide this remaining volume by the rate at which the pump supplies water:

600 units / (5 units/minute) = 120 minutes.

It will take 120 minutes to fill the tank to its full capacity.

Answer:

 [tex]x^2-12x+36= -6+36[/tex]

Step-by-step explanation:

Equation : [tex]x^2-12x = -6[/tex]

General equation : [tex]ax^2+bx+c=0[/tex]

So,we need to add and subtract [tex](\frac{b}{2})^2[/tex] for completing square.

So, next step of completing square :

 [tex]x^2-12x+6^2-6^2= -6[/tex]

 [tex]x^2-12x+36= -6+36[/tex]

Hence Step 2 shows lamar's next step and the solution to the equation

The solution to the equation after completing the square is:

(x - 6)² = 30

Lamar starts with the equation x² - 12x = -6.

Step 2: To complete the square, Lamar takes the coefficient of the x term, which is -12, divides it by 2, and then squares it. In this case, (-12/2)² = 36.

Lamar adds 36 to both sides of the equation to maintain its balance. By doing so, he effectively creates a perfect square trinomial on the left side of the equation.

x² - 12x + 36 = -6 + 36

Simplifying the right side, -6 + 36 equals 30.

The equation now becomes:

x² - 12x + 36 = 30

Now, Lamar can rewrite the left side of the equation as a perfect square. The left side is (x - 6)² because (x - 6)(x - 6) equals x² - 12x + 36.

(x - 6)² = 30

Thus, the solution to the equation x² - 12x = -6, after completing the square, is (x - 6)² = 30.

To find the general form of the equation of the quadratic function given a vertex and a point, we can proceed as follows:

The vertex form of the equation for a quadratic function can be expressed as:

\[ f(x) = a(x - h)^2 + k \]

where
- \( a \) is a coefficient that affects the width and direction of the parabola,
- \( (h, k) \) is the vertex of the parabola.

We've been given the vertex \( (h, k) = (-6, -1) \) and a point on the graph \( (x, y) = (-9, 8) \).

Let's use the vertex form and plug in the values of the vertex and the given point to solve for \( a \).

\[ 8 = a(-9 + 6)^2 - 1 \]
\[ 8 + 1 = a(-3)^2 \]
\[ 9 = a(9) \]
\[ a = 9 / 9 \]
\[ a = 1 \]

Now we know that \( a \) equals 1, and our vertex form equation becomes:

\[ f(x) = 1(x + 6)^2 - 1 \]

To write the equation in general form \( f(x) = ax^2 + bx + c \), we need to expand the equation:

\[ f(x) = 1(x + 6)^2 - 1 \]
\[ f(x) = (x^2 + 12x + 36) - 1 \]  (Expand the square)
\[ f(x) = x^2 + 12x + 36 - 1 \]

Finally, combine the constants:

\[ f(x) = x^2 + 12x + 35 \]

So the general form of the equation of the quadratic function given the vertex \( (-6, -1) \) and the point \( (-9, 8) \) is:

\[ y = x^2 + 12x + 35 \]

Here, \( a = 1 \), \( b = 12 \), and \( c = 35 \).

Answer:

d. 50 m

Step-by-step explanation:

1. You have the following information given in the problem above:

- The speed of the puck is 20 [tex]\frac{m}{s}[/tex] and experiences no frictional force.

- The time is 2.5 seconds.

2. Then, to calculate the distance, you must apply the following formula:

[tex]d=Vt[/tex]

Where [tex]d[/tex] is the distance, [tex]V[/tex] is the speed and [tex]t[/tex] is the time.

3. Now, you must substitute values into the formula, as below:

[tex]d=(20\frac{m}{s})(2.5s)[/tex]

4. Therefore, the result is:

[tex]d=50m[/tex]

Using the physics equation of distance = speed x time, it can be calculated that an ice-hockey puck moving at a constant speed of 20 ms^-1 for 2.5s would cover a distance of 50 m.

In Physics, the equation for distance can be expressed as distance = speed x time. In this case, the speed of the ice-hockey puck is given as 20 ms^-1 and the time is 2.5 s. By plugging these values into the formula, we get:
Distance = 20 ms^-1 x 2.5 s = 50 m. As a result, the ice-hockey puck will travel a distance of 50 meters in 2.5 seconds if it continues at a steady speed of 20 ms^-1 without any interference from frictional forces. Therefore the correct answer to this question is option d) 50 m.
