Given f(x) = 3x^2 + kx-1, and the remainder when f(x) is divided by x + 4 is 27, then what is the value of k?
Answer:
k=10
do long or synthetic division. the quotient = 3x + 22 with remainder 81
with long division first divide x into 3x^2 to get 3x. Then
3x times (x-4) = 3x^2-12x
subtract that from 3x^2+kx to get (k-12)x bring down the -7 to get
(k-12)x -7
you want a remainder of 81, so you want -4 times a constant to = -88 (-7-(-88)=81
4 x 22 =88. 22 is the constant
22=12+k
k=10

The length of the base of a triangle is twice its
perpendicular height. If its area is 36 cm2, find
its length and perpendicular height.
Answer: height = 6, length = 12
Step-by-step explanation:
Let the length of the height = x.
Then, the length of the base = 2x
The formula for the area of a triangle is base*height/2, which equals 36 in this case.
Therefore, x*2x/2 = 36
x^2 = 36
x = 6, 2x = 12
Thus, the height = 6 and then length = 12
Find the value of x.

Factors of a polynomial together constitute the polynomial by multiplication. The factored form of [tex]12c^9 + 28c^7[/tex] is [tex]= 4c^7(3c^2 + 7)[/tex]
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
[tex]a(b + c) = a\times b + a\times c[/tex]
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
Remember that many times, when using letters or symbols, we hide multiplication and write two things which are multiplied, close to each other. As in [tex]2 \times x = 2x[/tex]
The given polynomial is [tex]12c^9 + 28c^7[/tex]
To factor it, we can use the fact that 12 and 28 are both having 4 as common factor since:
[tex]12 = 4 \times 3 \\28 = 4 \times 7[/tex]

The LCM of two numbers is the product of the two numbers. Discuss
Answer:
Sometimes, not always.
Step-by-step explanation:
The LCM is the lowest common number between 2 numbers, sometimes it can represent the product of the 2 numbers, but sometimes it doesn't.
2 Examples:
2: 2, 4, 6, 8, 10.
3: 3, 6, 9, 12, 15.
6 is the least common multiple of 2 and 3 and it does represent the product between both numbers.
17: 17, 34, 51, 68, 85.
34: 34, 68, 102, 136, 170.
34 is the least common multiple of 17 and 34 and it does not represent the product between both numbers, the product is represented as 578.
We can prove that sometimes the LCM is the product between 2 numbers, and sometimes not.

absolute value cant be negative
If x > 2, find lx-2l
Help pleaseee
Explanation:
If x > 2, then x-2 > 0 after subtracting 2 from both sides.
Since x-2 is always positive when x > 2, this means the absolute value bars around the x-2 aren't needed. The results of |x-2| and x-2 are perfectly identical.
For example, if we tried something like x = 5, then
x-2 = 5-2 = 3|x-2| = |5-2| = |3| = 3Both outcomes are 3. I'll let you try other x inputs.
So because |x-2| and x-2 are identical, this means |x-2| = x-2 for all x > 2.
In short, we just erase the absolute value bars.
The ratio tables at the right show the comparison of books to games at Bert's Store and at Gloria's Store. Complete the ratio tables. Which store has the greater ratio of books to games? Explain.
Books : 4|number goes here| number goes here| number goes here| number goes here|
Games: 6|number goes here| number goes here| number goes here| number goes here|
Birt's store has a greater ratio of books to games in comparison to Gloria's store.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given the table:
Bert’s store
Books: 4,8,12,16,20.
Game: 6,12,18,24,30
Gloria’s store
Books: 5,10,15,20,25.
Games: 8, 16, 24, 32,40,
Since the fourth data of the birt store has an equal base to the third data of Gloria's store.
Thus, we can compare the data from the upper tables
So, 16 > 15
thus,
we can say that Bert's store has a greater ratio.

What is the center of a circle represented by the equation (x−5)2 (y 6)2=42? (−6,5) (−5,6) (5,−6) (6,−5).
The center of the circle is (5, -6). Option C shows the center of the circle.
What is a circle?
A circle can be defined as the set of all points in the plane that are a fixed distance from a fixed point on the plane.
Given that the equation of the circle is,
[tex](x-5)^2+(y+6)^2=42[/tex]
We know that the general form of the equation of the circle is,
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Where h, k is the center of the circle and r is the radius of the circle.
Compare the given equation with the general form of the equation, we get,
[tex](x-h) = (x-5)[/tex] and [tex](y-k) = (y+6)[/tex] and [tex]r^2 = 42[/tex]
For x-axis,
[tex](x-h) =(x-5)[/tex]
[tex]h = 5[/tex]
For y-axis,
[tex](y-k) = (y+6)[/tex]
[tex]k = -6[/tex]
Hence we can conclude that the center of the circle is (5, -6). Option C shows the center of the circle.

Step-by-step explanation:
The employees of a company were surveyed on questions regarding their educational background (college degree or no college degree) and marital status (single or married). Of the 600 employees, 400 had college degrees, 100 were single, and 60 were single college graduates. The probability that an employee of the company is single or has a college degree is: Select one: A. 0.10 B. 0.667 C. 0.733 D. 0.25
Probabilities are used to determine the chances of events
The probability that an employee of the company is single or has a college degree is 0.733
How to determine the probabilityThe given parameters are:
n = 600 --- the number of employees
College graduate = 400
Single graduate = 100
Single and college graduate = 60
The number of people that are college graduate or single are:
n(Single or college graduate) = 400 + 100 - 60
Evaluate
n(Single or college graduate) = 440
The probability is then calculated as:
p = 440/600
Evaluate the quotient
p = 0.733
Hence, the probability that an employee of the company is single or has a college degree is 0.733

Mark says he has 4/10 of a dollar. Matt says he has 40/100 of a dollar. Matt says he has more money than Mark. Is he correct? Why?
Group of answer choices
A.Matt is not correct because they have the same amount of money.
B.Matt is not correct because Mark has more money.
C.Matt is correct because 40 is greater than 4.
D.Mark is correct because 100 is greater than 10.
Answer:
A
Step-by-step explanation:
If you simplify 40/100, you should get 4/10, which is still the same amount that Mark has.
You simplify by finding the greatest common factor between 40 and 100. In this case, it is 10. So you divide 40 by 10 and 100 by 10 to simplify.

The 3rd term of an arithmetic sequence is -1 and the 7th term is -13. find the explicit formula for this sequence. What is a22?
Answer: Hopefully the math terms won't confuse anyone.
So in the series, a_3 = -1 and a_7 = -13. Since it's an arithmetic sequence, all the terms in the series can be represented as:
a_n = a_0 + n * k
where n is the nth number. K is a constant you add to reach the next term, and a_0 is the starting constant.
a_7 = a_0 + 7 * k
a_3 = a_0 + 3 * k
solving this system gives you that
k = - 3 and a_0 = 8
Hence:
a_22 = 8 + 22 * -3 = -58

Round your answer to the nearest hundredth. 25. 36 feet 27. 98 feet 100. 22 feet 128. 67 feet.
Angle of depression is the angle from horizontal line to the line of sight. The distance from building of the sculpture is: Option d: 128. 67 feet.
What is angle of depression?You look straight parallel to ground. But when you have to watch something down, then you take your sight up by moving your head down. The angle from horizontal to the point where you stopped your head is called angle of depression.
For the given case, referring to the figure, we have:
Length of BC = |BC| = 60 ft.
Length of AB = |AB| = x ft (distance of sculpture from building horizontally).
∠CAB = 25°
Thus, using tangent ratio from point of view of ∠CAB, we get:
[tex]\tan(25^\circ) = \dfrac{|BC|}{|AB|} = \dfrac{60}{x}\\\\x = \dfrac{60}{tan(25^\circ)} \approx 128.67 \: \rm ft[/tex]

We will see that the number of students that play both sports is given by the inequality:
5 ≤ x ≤ 9
How to find the number of students that play both sports?
We do know that in the class, there are 15 students.
Such that:
9 of them play basketball.11 of them play soccer.If you add these numbers, you get:
9 + 11 = 20
This gives more than the number of students that we have, to get the minimum number of students that play both sports we subtract the number of students:
20 - 15 = 5
5 students play both sports, but this is the minimum number.
There is also the case where out of the 11 students that play soccer, there are 9 that play basketball (so 9 students play both sports) and 4 students don't play any sport.
So the number of students that play both sports is given by the inequality:
