Determine which equation has the same solutions as the given equation.
x2 − 10x − 11 = 0
A.
(x − 5)2 = 21
B.
(x − 10)2 = 21
C.
(x − 10)2 = 36
D.
(x − 5)2 = 36
Answer:
D. [tex]\displaystyle (x - 5)^2 = 36[/tex]
Step-by-step explanation:
All you are doing is converting this Quadratic Equation to a Vertex Equation in Vertex Form by completing the square:
[tex]\displaystyle [\frac{b}{2}]^2 \\ \\ x^2 - 10x - 11 = 0 → x^2 - 10x + 25 - 36 = 0→ (x - 5)^2 - 36 = 0 \\ \\ (x - 5)^2 = 36[/tex]

A student surveyed 100 students and determined the number of students who take statistics or calculus among seniors and juniors. Here are the results.
Let A be the event that the student takes statistics and B be the event that the student is a senior.
What is P(A and B)?
A. 0.15
B. 0.33
C. 0.47
D. 0.68
Pr ( A & B ) , ie Probability (Senior Student with Statistics) = 0.15
Given : Event A = Student is senior, Event B = Student takes statistics
Total Students = Seniors with Statistics + Juniors with Statistics + Seniors with Calculus + Juniors with Calculus = 15 + 18 + 35 + 32 = 100 students Pr (A & B) , ie Probability (Senior Student with Statistics) = 15 studentsPr (A & B) = Favourable Students / Total Students = 15 / 100

Find the slope of the line.
-1/2
1/2
-2/1
2/1
Step-by-step explanation:
If the points are (-1/2, 1/2) and (-2/1, 2/1) then you can enter these into the Slope equation
(y1 - y2) / (x1 - x2)
1/2 - 2/1 = 1/2 - 4/2 = - 3/2 or - 1.5
-1/2 - (-2/1) = - 1/2 + 4/2 = 3/2 or 1.5
So your Slope is -1.5/1.5 = - 1

Neil, an artist, plans to paint and sell some miniature paintings. He just bought some brushes for $100, and paint and canvas for each painting costs $9; he will sell each painting for $10. Once Neil sells a certain number of his paintings, he will be breaking even. How many paintings will that be?
Answer: 100 paintings
Step-by-step explanation:
To calculate the breakeven point, use the following formula:
= Fixed cost / Contribution margin
The Fixed cost is the one that does not change which is the $100 spent on brushes.
Contribution margin = Sales price - variable cost(cost that he incurs per painting)
= 10 - 9
= $1
Breakeven point = 100/1
= 100 paintings
Ivan and Tanya share £150 in the ratio 4:1
How much more does Ivan get than Tanya
Answer:
Ivan gets £90 more than Tanya
Step-by-step explanation:
Given that
Total amount = £150
Ratio: 4:1
First of all we have to find the sum of ratio: 4+1 = 5
Now,
Ivan's Share:
[tex]= \frac{4}{5} * 150\\= 120[/tex]
Tanya's Share:
[tex]=\frac{1}{5} * 150\\= 30[/tex]
Ivan gets £120 and Tanya gets £30
The difference between their shares is the answer.
So,
[tex]= 120-30 = 90[/tex]
Hence,
Ivan gets £90 more than Tanya

the formula for the sum of the degree measures of the interior angles of a polygon is S=180(n-2) Solve for ,n, the number of sides of the polygon, in terms of S
NEED STEP BY STEP EXPLANATION
Answer:
n = (S + 360)/180Step-by-step explanation:
Given formula:
S = 180(n - 2)Solving for n:
S = 180(n - 2) ⇒ open parenthesisS = 180n - 360 ⇒ isolate n180n = S + 360 ⇒ divide both sides by 180n = (S + 360)/180[tex]S = 180(n - 2) \\ S = 180n - 360 \\ 180n =( S + 360) \\ n = \frac{(S+ 360)}{180} [/tex]
where, n =number of sides of polygon
S =sum of the degree measures of the interior angles of the polygon

The equations of three lines are given below. Line 1: y = - 3/4 x + 3 Line 2/8 x - 6y = 2 Line 3/- 3y = 4x + 7 For each pair of lines, determine whether they are parallel, perpendicular, or neither.
Answer:
No parallel lines
Lines 1 and 3 are perpendicular
Step-by-step explanation:
Given:
[tex]Line\ 1:y = -\frac{3}{4}x + 3[/tex]
[tex]Line\ 2: \frac{2}{8}x -6y = 2[/tex]
[tex]Line\ 3: 3y = 4x + 7[/tex]
Required
Determine if they are parallel, perpendicular or not
The slope intercept of a line has the form:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
First, we calculate the slope of each lines
[tex]Line\ 1:y = -\frac{3}{4}x + 3[/tex]
Compare the above to [tex]y = mx + b[/tex]
[tex]m_1 = -\frac{3}{4}[/tex]
[tex]Line\ 2: \frac{2}{8}x -6y = 2[/tex]
[tex]\frac{2}{8}x -6y = 2[/tex]
Make -6y the subject
[tex]-6y = 2 - \frac{2}{8}x[/tex]
Divide through by -6
[tex]y = -\frac{2}{6} + \frac{2}{8*6}x[/tex]
[tex]y = -\frac{1}{3} + \frac{1}{8*3}x[/tex]
[tex]y = -\frac{1}{3} + \frac{1}{24}x[/tex]
[tex]y = \frac{1}{24}x-\frac{1}{3}[/tex]
Compare the above to [tex]y = mx + b[/tex]
[tex]m_2 = \frac{1}{24}[/tex]
[tex]Line\ 3: 3y = 4x + 7[/tex]
[tex]3y = 4x + 7[/tex]
Divide through by 3
[tex]y = \frac{4}{3}x + \frac{7}{3}[/tex]
Compare the above to [tex]y = mx + b[/tex]
[tex]m_3 = \frac{4}{3}[/tex]
So, we have:
[tex]m_1 = -\frac{3}{4}[/tex]
[tex]m_2 = \frac{1}{24}[/tex]
[tex]m_3 = \frac{4}{3}[/tex]
None of the slopes are the same, so none of the lines are parallel.
However, lines 1 and 3 are perpendicular.
This is shown below
When the slope of two lines satisfy the following condition, then they are perpendicular.
[tex]m_1 = -\frac{1}{m_3}[/tex]
This gives:
[tex]-\frac{3}{4} = -\frac{1}{4/3}[/tex]
[tex]-\frac{3}{4} = -1/\frac{4}{3}[/tex]
Convert / to *
[tex]-\frac{3}{4} = -1*\frac{3}{4}[/tex]
[tex]-\frac{3}{4} = -\frac{3}{4}[/tex]

En una papelería sé adquirieron un paquete de 36 plumas este tiene un valor de 97.5 ¿Si el que compró el paquete va a vender cada pluma 75 centavos más cara cada pluma en cuanto La vendera?
Responder:
3,46
Explicación paso a paso:
Número de lápices comprados = 36
Costo total de los 36 lápices = 97,5
El precio unitario de cada lápiz será:
Costo total / número de lápices
97,5 / 36
= 2.708
El precio de venta por lápiz será:
Precio por lápiz + 75 céntimos
2,708 + 0,75
= 3.458
= 3,46
Por tanto, el precio de venta por lápiz será 3,46.
Susan was thinking of a number that when she multiplies it by two and then
divides that result by 4, then multiplies that result by itself, gives her a number
that when she subtracts 6 and then divides by 10, gives her the number 3. The
number Susan was originally thinking of was
Answer:
-4
Step-by-step explanation:
Let the number be x
If she multiplies the number by 2, it will become 2x
If divided by 4, it will be 2x/4, if she multiplies the result by itself, we will have:
2x/4(2x/4) = 4x/16
If she subtract the original number from 6 and divide by 10, we will have;
x-6/10
Equating both expressions
4x/16 = x-6/10
Cross multiply
4x(10)= 16(x-6)
40x =16x-96
40x-16x = -96
24x = -96
x = -96/24
x = -4
Hence the number is -4

Which of the following correctly describes the end behavior of the polynomial
function, f(x) = -3x^4 +2x^2 - x?
O A. The left end goes up and the right end goes down.
B. Both ends go up.
C. The left end goes down and the right end goes up.
D. Both ends go down.
Answer:
Both ends go down
Step-by-step explanation:
If the degree is EVEN, both ends pint the same way. If it is ODD, they point in opposite directions. The negative sign means the equation is flipped over the x axis and both ends go down.
The perimeter of a rectangle is 12x + 4. If the width is 2x,
the length of the rectangle is
Answer:
4x+2
Step-by-step explanation:
Perimeter = 2(width) + 2(length). So 12x+4 = 2(2x) + 2(length) .
12x+4 = 4x + 2(length) then subtract 4x from both sides to get 8x+4 = 2(length). In order to get length by itself you need to divide both side by 2.
4x+2 = length. Hope this helps!
