Obtain an expression that looks like this: 25+ 4 А B. X(S) = + s(s +6) S +6 S
A= ___________
B =____________
Answer:
[tex]A = \frac{2}{3}[/tex]
[tex]B = \frac{4}{3}[/tex]
Step-by-step explanation:
Given
[tex]X(s) = \frac{2s + 4}{s(s +6)}= \frac{A}{s} + \frac{B}{s + 6}[/tex]
Required
Find A and B
The expression can be rewritten as
[tex]\frac{2s + 4}{s(s +6)}= \frac{A}{s} + \frac{B}{s + 6}[/tex]
Take LCM of the right hand side
[tex]\frac{2s + 4}{s(s +6)}= \frac{A(s + 6 )+ Bs}{s(s +6)}[/tex]
Cancel out the denominators
[tex]2s + 4 = A(s + 6) + Bs[/tex]
Open Bracket
[tex]2s + 4 = As + 6A+Bs[/tex]
Reorder
[tex]2s + 4 = As +Bs+ 6A[/tex]
By direct comparison:
[tex]2s = As + Bs[/tex]
[tex]4 = 6A[/tex]
Solving [tex]2s = As + Bs[/tex]
Divide through by s
[tex]2 = A + B[/tex]
Solve for A in [tex]4 = 6A[/tex]
[tex]\frac{4}{6} = A[/tex]
[tex]A = \frac{4}{6}[/tex]
[tex]A = \frac{2}{3}[/tex]
Substitute [tex]\frac{2}{3}[/tex] for A in [tex]2 = A + B[/tex]
[tex]2 = \frac{2}{3} + B[/tex]
[tex]B = 2 - \frac{2}{3}[/tex]
LCM
[tex]B = \frac{6 - 2}{3}[/tex]
[tex]B = \frac{4}{3}[/tex]
Give another name for AE
Answer: [tex]\text{Line AE}=\overleftrightarrow{EA},\quad \overleftrightarrow{DA}, \quad \overleftrightarrow{AD},\quad \overleftrightarrow{ED},\quad \overleftrightarrow{DE},\quad \text{line r}[/tex]
[tex]\text{Segment AE}=\overline{EA}[/tex]
Step-by-step explanation:
The line can be named using ANY two points on the line or using the lower case letter.
The segment can be named by placing the letters in any order.
[tex]\overline{AE}=\overline{EA}[/tex]

6/5(8k+2)=-36solve equation
Answer:
k=-4
Step-by-step explanation:
[tex]\frac{6}{5} (8*-4+2) = -36[/tex]
Answer:
k = -4
Step-by-step explanation:
6/5 (8k + 2) = -36
5 x 6/5 (8k + 2) = -36 x 5
6(8k + 2) = -180
48k + 12 = -180
48k = -180 - 12
48k = -192
48k/48 = -192/48
k = -4
13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,
where & is the length (in yards) and w is the width (in yards).
a. Solve the formula for w.
P= 330 yd
b. Find the width of the field.
c. About what percent of the field
is inside the circle?
doc
10 yd
- 100 yd
Answer:
[tex]w = \frac{1}{2}(P - 24)[/tex]
[tex]w = 153\ yards[/tex]
Step-by-step explanation:
Given
[tex]P = 24 + 2w[/tex]
Require
Solving (a):
[tex]P = 24 + 2w[/tex]
Subtract 24 from both sides
[tex]P-24 = 24-24 + 2w[/tex]
[tex]P-24 = 2w[/tex]
Divide both sides by 2
[tex]\frac{1}{2}(P - 24) = \frac{2w}{2}[/tex]
[tex]\frac{1}{2}(P - 24) = w[/tex]
[tex]w = \frac{1}{2}(P - 24)[/tex]
Solving (b):
Substitute 330 for P un the expression in (1)
[tex]w = \frac{1}{2}(330 - 24)[/tex]
Evaluate the bracket
[tex]w = \frac{1}{2}(306)[/tex]
[tex]w = 153\ yards[/tex]

What is the equation of the line that is parallel to y = 2/3x+ 4 and passes through
the point (-7, 1)?
Answer:
The answer is
[tex]y = \frac{2}{3} x + \frac{17}{3} [/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = ⅔x + 4
Comparing with the general equation above
Slope = 2/3
Since the lines are parallel their slope are also the same
Slope of parallel line = 2/3
Equation of the line using point (-7 , 1) and slope 2/3 is
[tex]y - 1 = \frac{2}{3} (x + 7) \\ y - 1 = \frac{2}{3} x + \frac{14}{3} \\ y = \frac{2}{3} x + \frac{14}{3} + 1[/tex]
We have the final answer as
[tex]y = \frac{2}{3} x + \frac{17}{3} [/tex]Hope this helps you

I don’t know how to make a rule:(
Answer:
*assuming you know the concept of proportionality*
since L is directly proportional to T, an increase in L will result in an increase in T
so the solution of the first part is increases
in part 2, y is inversely proportional to x
which means that an increase in y will result in a decrease in x and vice-versa
So the answer of the second part is decreases
in part 3, since x is directly proportional to y, an increase in x will result in an increase in y
help!! 2x - 8 + 3x - 12 = 60
Answer:
x=16
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x−8+3x−12=60
2x+−8+3x+−12=60
(2x+3x)+(−8+−12)=60(Combine Like Terms)
5x+−20=60
5x−20=60
Step 2: Add 20 to both sides.
5x−20+20=60+20
5x=80
Step 3: Divide both sides by 5.

1. Find two functions f(x) and g(x) such that f[g(x)] = x but g[f(x)] does not equal x.2. State the vertical, horizontal asymptotes and zeros of the rational function, f(x) = {x^2+3x+2}/{x^2+5x+4}.Why is there no zero at x = –1?3. Give an example and explain why a polynomial can have fewer x-intercepts than its number of roots.
Answer:
1. [tex]f(x)=x^{2}[/tex] and [tex]g(x)=-\sqrt{x}[/tex]
2. Vertical Asymptote: x=-4
Horizontal Asymptote: y=1
Zeros: (-2,0)
Because the graph will have a hole at x=-1. This is, the graph is not defined for that particular x-value.
3. [tex]f(x)=x^{2}+4[/tex]
It has two complex roots, so there is no place in the graph where it crosses the x-axis.
Step-by-step explanation:
1. If we find the composite function f[g(x)] with the functions:
[tex]f(x)=x^{2}[/tex] and g(x)=-x, we will get the following:
[tex]f[g(x)]=(-\sqrt{x})^{2}[/tex]
which simplifies to
f[g(x)]=x
on the other hand, if we find g[f(x)] we will get the following:
[tex]g[f(x)]=-\sqrt{x^2}[/tex]
which simplifies to:
g[f(x)]=-x
2.
Before finding the asymptotes, it's a good idea to factor both the numerator and denominator of the function, so we get:
[tex]f(x)=\frac{x^{2}+3x+2}{x^{2}+5x+4}[/tex]
[tex]f(x)=\frac{(x+2)(x+1)}{(x+4)(x+1)}[/tex]
we can now see that this function can be simplified. It is important to simplify this function so we don't confuse vertical asymptotes with holes in the graph, so when simplifying we get the following:
[tex]f(x)=\frac{x+2}{x+4}[/tex]
now we can set the denominator equal to zero.
x+4=0
and solve for x:
x=-4 this is our vertical asymptote.
For the horizontal asymptote, there is a rule that tells us that if the polynomials on the numerator and denominator have the same degree (the same greatest power), then the horizontal asymptote is found by dividing the lead coefficient of the polynomial on the numerator by the lead coefficient on the denominator. In this case the lead coefficients are 1 and 1 so the horizontal asymptote is:
[tex]y=\frac{1}{1}[/tex]
so the horizontal asymptote is at:
y=1.
The zeros of the function are located at the x-values that will turn the numerator of the simplified fraction equal to zero, so we get:
x+2=0
x=-2
so the only zero will be located at (-2,0)
x=-1 is not a zero because the original function is not defined for x=-1, there is a hole in the graph at this x-value.
Take a look at the graph of the function (See attached picture)
3.
This will happen when there are no real zeros. Take for example the function:
[tex]f(x)=x^{2}+4[/tex]
In this case this problem has 2 non-real zeros:
[tex]x^{2}+4=0[/tex]
[tex]x^{2}=-4[/tex]
[tex]x=\sqrt{-4}[/tex]
so:
x=2i or x=-2i
since they are complex numbers they cannot be graphed on a coordinate axis, so the graph will not cross the x-axis. See attached picture.

Roman is considering buying shares of GHI stock. The stock currently sells for $60 per share. The stock changes in value at 8:00 am each day, either increasing in value by $10 or decreasing in value by $1. The stock will increase in value with 90% probability, and decrease in value with 10% probability. The stock follows a random walk. In three days, what is the probability that GHI is less than $70?
Answer:
The Probability that the GHI is less than $70 in three days is 1% or 0.01
Step-by-step explanation:
Here, we want to find the probability that the GHI is less than $70.
So what we do here is to find the scenarios that could make the $60 less than $70 is three days;
Scenario 1;
Two days decrease and one day increase
That will bring the value to 60 -1-1 + 10 = $68 which is less than 70
Scenario 2;
Three days decrease
That will bring the value to
60-1-1-1 = 57 which is less than 70
Any other possible scenario to make the value of the share less than 70? NO !
For the 1st case scenario;
Two days decrease and one day increase;
The scheduled probabilities will be as follows;
Kindly recall, probability of increase = 90% = 90/100 = 0.9
Probability of decrease = 10% = 10/100 = 0.1
So probability in scenario 1 will be;
P(Two days decrease and one day increase)
= 0.1 * 0.1 * 0.9 = 0.009
Kindly note this can happen in any order and since no order was specified, we do not need to consider other cases
Scenario ii
Three days decrease
That will be;
P(three days decrease) = 0.1 * 0.1 * 0.1 = 0.001
So the addition of both since we will be having either of the two and or means addition in probability will be ;
0.001 + 0.009 = 0.01 = 1%

What is the midpoint of A F?
Hey there! I'm happy to help!
A is -10 and F is -5. To find the number in between two numbers, you add them and divide by 2.
-10+(-5)=10-5=-15
-15/2=-7.5
So, the midpoint is -7.5, which is right in between C and D.
