(-3j²k³)²(2j²k)³ = When a power is raised to a power the exponents have to be multiplied.
= (-3²j⁽²*²⁾k⁽³*²⁾)(2³j⁽²*³⁾k³) = We can take out the constants
= (9)(8)(j⁴k⁶)(j⁶k³) = We can group the same variables
= 72(j⁴j⁶)(k⁶k³) = When multiplying two powers that have the same base, you have to add the exponents.
= 72 j⁽⁴⁺⁶⁾k⁽⁶⁺³⁾ = 72j¹⁰k⁹
Answer = 72j¹⁰k⁹

Use the vertex (h, k) and a point on the graph (x, y) to find the general form of the equation of the quadratic function.
(h, k) = (−6, −1), (x, y) = (−9, 8)
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 \( c = 35 \).

Lamar is solving the equation x^2 - 12x = -6 by completing the square. Which shows lamar's next step and the solution to the equation?
step 1: x^2 -12x = 6
step 2: x^2 - 12x + 36 = -6 +36
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
How to find the next stepLamar 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.

Write the equation of the line through the given point. Use slope-intercept form. (−9,7) perpendicular to y=-5/6x+6
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
y = mx + by = 6/5x + b7 = (6/5)(-9) + b7 = -54/5 + b89/5 = b17.8 = bPlug "b" back into the slope-intercept form along with your equation's slope
y = mx + b
ANSWER: y = 6/5x + 17.8(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.
Explanation: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

A pump can supply 5 units of water per minute. How many minutes will it take to fill a 800 unit tank to its full capacity if it is already 1/4 full of water?
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.
Which equation illustrates the additive inverse property?
A.
6 + 0 = 6
B.
6 + (-6) = 0
C.
6 × 0 = 0
D.
-6 + 6 = 6 + (-6)
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.

Step-by-step explanation:
Patients who are addicted to cocaine are sometimes using the drug to combat depression. As such, sometimes addicts are given antidepressant medications to prevent relapse. A three-year study compared the effects of two such medications, lithium and desipramine, along with a placebo for 72 cocaine users wishing to break the habit. The patients were put into 3 groups of 24, and given 1 of the 3 treatments at random. This two-way table illustrates the results.
Treatment Relapse No relapse Total
Desipramine 10 14 24
Lithium 18 6 24
Placebo 20 4 24
Total 48 24 72
Give a conditional relative frequency for relapse among patients who took lithium.
A. 18/72 = 25%
B. 27/72 = 33.33%
C. 18/24 = 75%
D. 48/72 = 66.67%
Answer:
Option C, 18/24 = 75%
Step-by-step explanation:
Patients who were addicted to cocaine were divided into 3 groups of 24.
Each group was treated with three different drugs. One group of 24 patients were put on Lithium for treatment out of 24 patients who relapsed were 18.
So conditional relative frequency for relapse among patients who took Lithium would be :
Relative frequency of patients = (patients relapsed) / (total number of patients)
Relative frequency = [tex]\frac{18}{24}[/tex] = 75%
Option C, 18/24 = 75% would be the answer.

Principal: $750,00; annual interest rate: 5 percent. What is the interest after 6 months?
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:
acute - less than 90°right - exactly 90°obtuse - more than 90°straight - exactly 180°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
