Step-by-step explanation:
[tex](8k^4-3k^2)(5k^2)=\\\\8k^4(5k^2)-3k^2(5k^2)=\\\\8(5)(k^{4+2})-3(5)(k^{2+2})=\\\\40k^6-15k^4[/tex]
Result of [tex]8k^{4} -3k^{2}[/tex] multiplied by [tex]5k^{2}[/tex] is [tex]40k^{6}-15 k^{4}[/tex]
Algebra and Exponent
To answer this question you need to know about algebra and exponent rule.
[tex]8k^{4} -3k^{2}[/tex] multiplied by [tex]5k^{2}[/tex]
It means the operation will become:
[tex]5k^{2} (8k^{4} -3k^{2} )=[/tex]
First, [tex]8k^{4} -3k^{2}[/tex] can't be calculate because of different variable. Even though they both use the letters '[tex]k[/tex]', [tex]k^{4}[/tex] dan [tex]k^{2}[/tex] cannot be added because they have different powers. In algebraic addition, addition can only be done on the same variables and which have the same power.Because [tex]8k^{4} -3k^{2}[/tex] can not be calculated, then we directly calculate the multiplication [tex]5k^{2} (8k^{4} -3k^{2} )[/tex]The way to calculate algebraic multiplication with 2 or more variables is the way I call 'rainbow'.
[tex]5k^{2} (8k^{4} -3k^{2} )=[/tex]
[tex]5k^{2}[/tex] multiplied by [tex]8k^{4}[/tex], [tex]5k^{2}[/tex] multiplied by [tex]-3k^{2}[/tex] first, then the two are added.
Let's multiply one by one first[tex](5k^{2}) (8k^{4} )=[/tex]
The way to multiply this is by: numbers multiplied by numbers and letters multiplied by letters
[tex]=5k^{2} (8k^{4} -3k^{2} )\\=((5)(8))((k^{2} )(k^{4} ))\\=40((k^{2} )(k^{4} )[/tex]
Then how to multiply the letters, this uses the rule of exponents. If there are 2 same variables are multiplied, then the result is a variable with the power of the sum of the two powers.
[tex]a^{m} a^{n} =a^{m+n}[/tex]
Which means,
[tex]k^{2}k^{4} =k^{6}[/tex]
Then,
[tex]=5k^{2} (8k^{4} -3k^{2} )\\=((5)(8))((k^{2} )(k^{4} ))\\=40((k^{2} )(k^{4} )\\=40k^{6}[/tex]
Also same with above,
[tex]=(5k^{2} )(-3k^{2} )\\=((5)(-3))((k^{2} )(k^{2} )\\=-15k^{4}[/tex]
Add the result of two operation above[tex]=5k^{2} (8k^{4} -3k^{2} )\\=((5k^{2})(8k^{4})+((5k^{2})(-3k^{2})\\=(40k^{6})+(-15k^{4} )\\=40k^{6}-15k^{4}[/tex]

find the value of x and y
Answer:
∴ x = 10.7 (to 3sf), y = 18
Step-by-step explanation:
(3x)° + (4x-15)° = 90° (right angle given) ------ equation (1)
(3x)° + (4x-15)° + (5y)° = 180° (adjacent angles on a straight line) ------ equation (2)
From equation (1),
3x + 4x - 15 = 90
7x = 75
∴ x = 10.7 (to 3sf)
Subtract equation (1) from equation (2):
(3x+4x-15+5y) - (3x+4x-15) = 180 - 90
5y = 90
∴ y = 18

A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associate is $800 and the daily rate for each partner is $1700. The law firm assigned a total of 14 lawyers to the case and was able to charge the client $19300 per day for these lawyers' services. Determine the number of associates assigned to the case and the number of partners assigned to the case.
The Number of Associates and Number of Partners assigned to the case by the law firm is 5 and 9 respectively. We can solve this by using the concept of Linear Equation.
Given that,
Daily rate charged to the client for each Associate = $ 800
Daily rate charged to the client for each Partner = $ 1700
Let number of Associates assigned to case = X
And number of Partners assigned to case = Y
So, According to Question
X + Y = 14 ----(1)
800X + 1700Y = 19300 ---(2)
From the equation (1) , Y = 14 – X
Substituting the value of Y into equation (2) we get,
800X + 1700(14-X) = 19300
800X + 23800 – 1700X = 19300
23800 – 900X = 19300
23800 – 19300 = 900X
4500=900X
4500/900 = X
X = 5
Put the value of X into equation (1),
5 + Y = 14
Y = 14 -5
Y = 9
So we let the number of Associates assigned to case X and number of partners assigned to case Y and the value of X is 5 and Y is 9 .
Hence the number of Associates assigned to the case is 5 and the number of Partners assigned to the case is 9.

The equation of the line perpendicular to the line 3x - 6y = - 8 is y = - 2x - 15 and of line parallel to the line 3x - 6y = - 8 is y = x/2.
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is a line 3x - 6y = - 8.
We have -
3x - 6y = - 8
3x = 6y - 8
6y = 3x - 8
y = x/2 - 4/3
For a parallel line -
slope = 1/2
y = x/2 + c
for the point (- 6, - 3), we can write -
-3 = -6/2 + c
-3 = -3 + c
c = 0
Equation : y = x/2
For a perpendicular line -
y = - 2x + c
for the point (- 6, - 3)
- 3 = - 2 x - 6 + c
- 3 = 12 + c
c = - 15
Equation : y = - 2x - 15
Therefore, the equation of the line perpendicular to the line 3x - 6y = - 8 is y = - 2x - 15 and of line parallel to the line 3x - 6y = - 8 is y = x/2.

How to determine the amount owed in six years?The given parameters about the compound interest are
Principal Amount, P = $5300
Interest Rate, R = 8%
Time, t = 6 years
To calculate the amount owed, we make use of the following formula
A = P + CI
Where
Compound interest, CI = P(1 + R)^t - P
So, the equation becomes
A = P + P(1 + R)^t - P
Evaluate the like terms
A = P(1 + R)^t
In this question, the formula is given as
A = P(1 + r/n)^nt
Where
n = 12, i.e compounded monthly
Substitute the known values in the above equation
A = 5300 * (1 + 8%/12)^(6*12)
Express 8% as decimal
A = 5300 * (1 + 0.08/12)^(6*12)
Evaluate the sum
A = 5300 * (1.01)^(6*12)
Evaluate the exponent
A = 5300 * 2.05
Evaluate the product
A = 10865

40 ahletes are surveyed it is found that 30 athletes play tennis and 10 play gold 5 play both. what is the probability an athlete plays golf or tennis but not both?
The probability an athlete plays golf or tennis but not both = 0.75
Probability:The ratio of favorable outcomes to all possible outcomes of an event is known as probability.
The formula to calculate the probability of an event is given by
Probability(E) = Favorable Outcomes/Total Outcomes
Here we have 40 athletes,
Number of athletes who plays both tennis and golf = 5
Number of athletes who plays tennis = 30
=> Number of athletes who plays only tennis = 30 - 5 = 25
Number of athletes who plays golf = 10
Number of athletes who plays only golf = 10 - 5 = 5
From the above calculations,
Number of athletes who plays tennis or golf but not both = 25 + 5 = 30
Probability that athletes play golf or tennis but not both = 30/40 = 0.75
Therefore,
The probability an athlete plays golf or tennis but not both = 0.75

Write a two-column proof.
Given: Line AB ∥ Line DC, ∠B ≅ ∠D
Prove: Line BC ≅ Line DA
Here is the proof:
1. Length AB = Length DC
2. Angle BAC = Angle ACD (AB is parallel to CD, so the opposite interior angles are equal)
3. AC length = AC length (2 lines coincide)
Principle of Side - Angle - Side
then the two triangles are said to be congruent
So Length BC = Length DA
Congruence is a condition where two flat shapes have the same size and are said to be congruent.
The characteristics of two triangles that are said to be congruent are:
1. When the pairs of corresponding sides are equal in length. Usually called the side-by-side criterion.
2. Two pairs of corresponding sides are equal in length and the angles between them are equal. Commonly referred to as the side-angle-side criterion.
3. Two pairs of congruent angles and the same side lengths. Also known as angle-side-angle
