Which of the following is an equivalent equation obtained by completing the square of the expression below? x^2+6x−8=0 A (x+3)^2=8 B (x+3)^2=17 C (x+3)^2=1 D x^2+6x+6=14
Answer:
Solving the equation [tex]x^2+6x-8=0[/tex] by completing the square method we get [tex]\mathbf{(x+3)^2=17}[/tex]
Option B is correct option.
Step-by-step explanation:
We need to solve the equation [tex]x^2+6x-8=0[/tex] by completing the square method.
For completing the square method: we need to follow: [tex]a^2+2ab+b^2=(a+b)^2[/tex]
We are given:
[tex]x^2+6x-8=0[/tex]
Solving by completing the square
[tex]x^2+2(x)(?)+(?)^2-8=0[/tex]
We need to find ? in our case ? is 3 because 2*3= 6 and our middle term is 6x i,e 2(x)(3)=6x.
So, adding and subtracting (3)^2
[tex]x^2+2(x)(3)+(3)^2-8-(3)^2=0\\(x+3)^2-8-9=0\\(x+3)^2-17=0\\(x+3)^2=17[/tex]
So, solving the equation [tex]x^2+6x-8=0[/tex] by completing the square method we get [tex]\mathbf{(x+3)^2=17}[/tex]
Option B is correct option.

What is the initial value and what is the rate of growth
Answer:
initial value is 1200, rate of growth is 0.3
Step-by-step explanation:
A(t) = P(1+r)^t
p= initial value
r= rate of growth
A(t)= amount after
t= time
The initial value is 1200 and rate of growth is 0.3.
What is Exponential function?An exponential function is a mathematical function of the following form: f ( x ) = [tex]a^x[/tex] where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e
Given:
Function: Y=1200 x [tex](1+0.3)^t[/tex]
Now, We know using the Amount formula
A(t) = P[tex](1+r)^t[/tex]
where, p= initial value
r= rate of growth
A(t)= amount after
t= time
Then, Comparing it to the given function we have
Initial Value = 1200
and, Rate of Growth = 0.3

There is a dice game at the casino that costs $3 to play. A player rolls two dice. If the player gets a sum of 2 or 12 he or she gets back $ 28 (wins $25). the person gets a 7he or she gets back $5 (wins $2). If the player rolls anything other than a 2, 12 or 7 he or she gets nothing back (loses $3). Find the expected value for the player?
Answer:
The expected value for the player is -$0.63.
Step-by-step explanation:
The dice game has the following rules:
The game costs $3 to play. A player rolls two dice. If the player gets a sum of 2 or 12 he or she gets back $ 28 (wins $25). If the person gets a 7 he or she gets back $5 (wins $2). If the player rolls anything other than a 2, 12 or 7 he or she gets nothing back (loses $3).The outcomes for a sum of 2 or 12 are: {(1, 1) and (6, 6)}
The probability of a sum of 2 or 12 is: 2/36 = 0.055.
The outcomes for a sum of 7 is: {(1, 6), (2, 5), (3, 4), (4, 3), (5, 2) and (6, 1)}
The probability of a sum of 7 is: 6/36 = 0.167.
The probability of a sum other than 2, 12 or 7 is: 1 - 8/36 = 0.778
The probability distribution is:
Result X P (X)
Sum 2 or 12 $25 0.055
Sum 7 $2 0.167
Others -$3 0.778
Total 1.000
Compute the expected value as follows:
[tex]E(X)=\sum x\cdot P(x)\\\\[/tex]
[tex]=(25\times 0.055)+(2\times 0.167)+(-3\times 0.778)\\\\=1.375+0.334-2.334\\\\=-0.625\\\\\approx -0.63[/tex]
Thus, the expected value for the player is -$0.63.
What number is 28.5% of 460?
Answer:
131.1
Step-by-step explanation:
Step 1: Our output value is 460.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$460=100\%$.
Step 4: Similarly, $x=28.5\%$.
Step 5: This results in a pair of simple equations:
$460=100\%(1)$.
$x=28.5\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{460}{x}=\frac{100\%}{28.5\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{460}=\frac{28.5}{100}$
$ x=131.1$
Meaning that 28.5 of 460 is 131.1

reflect triangle stu across line st which of these is a valid reason why the image u will coincide with j
1 the image u and j are on the same side of st and make the same angle with it at t
2 the image u and j are the same distance along the same ray from t
3 the image of u and j will not coincide after a reflection over st
4 none of the above
Answer:
4. None of the above
Step-by-step explanation:
Reflection is a type of transformation that can be used to change the orientation of a given figure or shape without changing it size and shape.
When triangle STU is reflected across ST, the image U coincides with J because the two are on the opposite side and at the same distance from ST. Therefore, J is like the image of U.

To raise money for after-school programs at an elementary school, a group of parents is holding a weekend of games in a community center. They charge $8 per person for entry into the event. The group would like to earn at least $600, after paying for the cost of renting the space, which is $40 an hour. If x represents the number of entry tickets sold and y the hours of space rental, which inequality represents the constraints in the situation? Group of answer choices 8x-40y 600 8x-40y > 600
Answer:
[tex]8x-40y\geq 600[/tex] and [tex]x>0,y>0[/tex]
Step-by-step explanation:
The number of people is [tex]x[/tex] and the number of hours they are present in the space is [tex]y[/tex].
Per person entry cost is $8.
Per hour cost of rent is $40.
They plan to earn a minimum of $600.
Donations by all the people entering the space is [tex]8x[/tex]
Total cost of renting the space is [tex]40y[/tex] which will be subtracted from the total amount of donations.
The inequality that represents the situation is [tex]8x-40y\geq 600[/tex] and [tex]x>0,y>0[/tex].
