In the xy-coordinate plane, the points (4, 2) and (-1, k) are on a line that is perpendicular to the line y=2x+1 . What is the value of k
A line of two points (4, 2) and (-1, k) is perpendicular to the line y=2x+1, then k = 9/2.
Given a line with equation y = mx + c, the slope is denoted by m.
Given 2 points with slopes m₁ and m₂, those two lines are perpendicular if:
m₁ x m₂ = -1
The given line equation is: y = 2x+1
Hence,
m₁ = 2
Compute the slope from 2 points: (4, 2) and (-1, k)
m₂ = (k - 2) / (-1 - 4)
m₂ = (-1/5) (k - 2)
Use the condition for perpendicular lines:
m₁ x m₂ = -1
2 x (-1/5) (k - 2) = -1
2k - 4 = 5
2k = 9
k = 9/2

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 2(m∠Y) − 75°. Find m∠Y.
m∠s + m∠y = 90
m∠s = 90 - m∠y
m∠s= 2(m∠y) - 75
90 - m∠y = 2 m∠y -75
90 + 75 = 3 (m∠y)
165 = 3 (m∠y)
55= m∠y
2x² + 5x, what will it a Perfect Square? make
Answer:
2x² + 5x + c = 0
For this quadratic equation to have one double root, the discriminant must equal 0.

given f(x)= 24x^3+14x^2-11x-6 and (2x+1) is a factor, write f(x) as a set of linear factors
The linear factors of the given polynomial is (2x+1)(4x+3) and (3x-2).
What is factorization?The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.
The given function is f(x)=24x³+14x²-11x-6 and one of the factor is (2x+1).
Here, 24x³+14x²-11x-6 can be written as 24x³+12x²+2x²+1x-12x-6
12x²(2x+1)+1x(2x+1)-6(2x+1)
= (2x+1)(12x²+1x-6)
= (2x+1)(12x²+1x-6)
= (2x+1)(12x²+9x-8x-6)
= (2x+1)[3x(4x+3)-2(4x+3)]
= (2x+1)(4x+3)(3x-2)
Therefore, the linear factors of the given polynomial is (2x+1)(4x+3) and (3x-2).

The time required find an entry in a list is uniformly distributed from 0 to 60 minutes. What is the probability that I will find the entry I am searching for in between 30 and 32 minutes
Answer:
The probability of finding the entry in the period between 30 and 32 minutes is 5%.
Step-by-step explanation:
Given that the time required to find an entry is uniformly distributed between 0 and 60 minutes, it implies that 100% of the chances are in that period of time distributed equally. Therefore, since 100/60 is equal to 1.66, each minute has a 1.66% chance that the entry will be there.
Thus, since between minutes 30 and 32 there are 3 minutes in total (30, 31 and 32), to determine the probabilities of finding the entry in that period it is necessary to perform the following calculation:
1.66 x 3 = X
5 = X
Therefore, the probability of finding the entry in the period between 30 and 32 minutes is 5%.

a unit vector is a vector with length . the length of a vector is also called its norm. given any vector what is the unit vector pointing in the same direction as ? answer in terms of and the norm of the vector . (type x for the vector , and norm(x) for the norm of the vector .)
The answer in terms of x and the norm of the vector is: x / norm(x)
The unit vector pointing in the same direction as vector x can be calculated as:
x / ||x||
where ||x|| represents the norm (length) of the vector x.
x / norm(x)
In mathematics, a vector is an object that has both magnitude and direction. It can be represented by an arrow, where the length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction of the vector. Vectors can be represented in different coordinate systems such as Cartesian, polar, or spherical coordinates.
In linear algebra, vectors are often represented as n-tuples of real numbers, where n is the dimension of the vector space. For example, a 2-dimensional vector can be represented as (x, y), and a 3-dimensional vector can be represented as (x, y, z). Vectors can be added and subtracted, scaled by a scalar, and used in operations such as dot product and cross product.

The scale factor of the perimeters from figure A to figure B is 1.5. Scale factor is the ratio of any two corresponding lengths in two similar figures.
Here, the two figures are similar, that is why we can find the scale factor by dividing corresponding sides of one figure by the corresponding sides of another figure. We will find the scale factor for the perimeter of figures A and B below:Perimeter of figure A = 12 + 10 + 18 = 40 unitsPerimeter of figure B = 15 + 15 + 15 = 45 unitsTo find the scale factor of the perimeters, we divide the perimeter of figure B by the perimeter of figure

A pair of jeans was 30% off the original price. The sale resulted in $24 discount.
Answer:
$80 is the 100% original price
The sale price is $56 with 30% off and $24 in savings.
Step-by-step explanation:
We can write a proportion. We know that $24 is a 30% off discount of an unknown original price. Let's call it x. We write equal ratios of comparing percent and comparing the 24 to the original price. We then set them equal.
We then cross multiply across the equal sign from numerator to the opposite numerator.
30(x)=24(100)
30x=2400
We divide to find x.
x=80.
Since we saved $24 as a discount, the sale price would be 80-24=56.

(-2) (4+6)+(-2) 6 / (-2) (4-1) simplified
The simplified form of the expression is \(-32\).
To simplify the expression, we can perform the calculations written below step by step:
\(\(\frac{{-2(4+6)+(-2)6}}{{-2(4-1)}}\)\)
We follow the order of operations (PEMDAS/BODMAS):
Step 1: Simplify within parentheses:
\(\(4+6 = 10\)\).
Step 2: Perform multiplications and divisions from left to right:
\(\(-2(10) = -20\) and \(-2(4-1) = -2(3) = -6\)\).
Step 3: Evaluate the remaining additions and subtractions:
\(\(-20 + (-2) \cdot 6 = -20 - 12 = -32\)\).
Therefore, the simplified form of the expression \(\(\frac{{-2(4+6)+(-2)6}}{{-2(4-1)}}\) is \(-32\).\)
When simplifying an expression, several factors need consideration. First, apply the order of operations correctly, respecting parentheses and exponents. Next, combine like terms by adding or subtracting them. Distribute and simplify within parentheses or brackets as needed. Pay attention to negative signs and ensure their proper placement.
Finally, review the simplified expression to ensure accuracy and validity within the given context.
Note: The complete question is:
