1. 3(2x-4) = -36
2. 5x - 6x - x = 18
3. 5 - 2(3x - 1) = 31
Answers
Answer:
1. Yes
2. No
3. Yes
Step-by-step explanation:
We have three equations where x is equal to -4. We are then asked if -4 are a solution to these equations.
To solve we need to substitute the x in every equation for -4. Start :
1.
3(2(-4) - 4) = -36
3(-8 - 4) = -36
-24 - 12 = -36
Therefore -4 is a solution.
2.
5(-4) - 6(-4) - (-4) = 18
-20 + 24 + 4 = 18
4 + 4 = 18
8 ≠ 18
Therefore -4 is not a solution.
3.
5 - 2(3(-4) - 1) = 31
5 - 2(-12 - 1) = 31
5 - 2(-13) = 31
5 + 26 = 31
Therefore -4 is a solution.

Explanation:
Use the equation
Work done = rate x time
If you can complete the calls in 6 days, then your rate is N/6 calls per day.
By similar reasoning, your classmate has a rate of N/4 calls per day. Working together , we can write:
Combined rate x time = total calls
(N/6 + N/4) t = N
Nt/6 + Nt/4 = N
Multiply both sides by 24/N:
4t + 6t = 24

In a carnival game, there are six identical boxes, one of which contains a prize. A contestant wins the prize by selecting the box containing it. Before each game, the old prize is removed and another prize is placed at random in one of the six boxes. Is it appropriate to use the binomial probability distribution to find the probability that a contestant who plays the game five times wins exactly twice?
A) Yes. The five trials are independent, have only two outcomes, and have the same P(success); n = 5, r = 2, p = 1/5.
B) Yes. The five trials are independent, have only two outcomes, and have the same P(success); n = 2, r = 5, p = 1/6.
C) No. The five trials are independent, but have more than two outcomes.
D) Yes. The five trials are independent, have only two outcomes, and have the same P(success); n = 5, r = 2, p = 1/6.
Answers
Answer:
D) Yes. The five trials are independent, have only two outcomes, and have the same P(success); n = 5, r = 2, p = 1/6.
Step-by-step explanation:
The Number of boxes = 6
Box containing a prize = 1
Probability of success, p = box containing a price / number of boxes = 1 /6
Number of trials = 5
Probability of success on exactly 2 trials, r = 2
Hence,
P(r = 2) = nCr * p^r * (1-p)^(n-r)
n = 5 ; r = 2 ; p = 1/6
Using a binomial probability calculator :
P(r = 2) = 0.1608
Ana has won a lottery.

Assuming (a) interest at an annual rate of 5% compounded annually, or (b) interest at an annual rate of 6% compounded continuously, which option should she choose under the consideration of cash value only?
A) If the interest is at the annual rate of 5%, compounded annually, then the present value of the five installments is $______. B) If the interest is at the annual rate of 6%, compounded continuously, then the present value of the five installments is $______.
Answers
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
She can either take it in five installments of $60,000 annually, starting from now; or she can take a lump-sum of $255,000 now.
First, we determine the value of the 5 installments using a 5% annual compounded rate.
We calculate the future value, and then the present value:
FV= {A*[(1+i)^n-1]}/i
A= annual payments
FV= {60,000*[(1.05^5) - 1]} / 0.05
FV= $331.537.88
PV= FV/(1+i)^n
PV= $259,768.60
At an annual rate of 5% compounded annually, she should choose the five installments instead of the $255,000.
Now, if the annual rate is 6% continuously compounded.
First, we need to calculate the effective interest rate:
r= e^i - 1
r= effective inerest rate
r= e^0.06 - 1
r= 0.0618
FV= {60,000*[(1.0618^5) - 1]} / 0.0618
FV= 339,443.23
PV= 339,443.23/1.0618^5
PV= $251,509.01
At an annual rate of 6% compounded continuously, she should choose the $255,000.

For all Plato users.
We have to find the sum of the series has been given as.

If the series has been given as,
[tex]\sum_{n=1}^{k}a(r)^{n-1}[/tex] -------(2)
It's a geometric series with first term 'a' and common ratio 'r'.
Comparing both the expressions (1) and (2),

Number of terms 'n' = 8
Sum of the k terms of this series is given by,

Answers
Answer:
The answer is below
Step-by-step explanation:
Chancellor Manufacturing makes two pumps for use in household reef aquariums. The Standard pump (Model A) requires 4.5 lbs of stainless steel while the Deluxe lightweight pump (Model B) 3.0 lbs of stainless steel. There are 63 lbs of stainless steel available during this production period. The combined production of both pumps must be at least 12 pumps. There are orders for at least 6 of the lightweight Model B. Lastly, management has decided that no more than 15 Model B pumps be produced.
The cost to produce one Standard pump is $150 and to produce one Deluxe pump is $210.
Solution:
a) Let x represent model pump A and let y represent model pump B.
Since There are 63 lbs of stainless steel available, hence:
4.5x + 3y ≤ 63
Both pumps must be at least 12 pumps. Therefore:
x + y ≤ 12
There are orders for at least 6 of the lightweight Model B:
y ≥ 6
Also, no more than 15 Model B pumps be produced:
y ≤ 15
The cost to produce one Standard pump is $150 and to produce one Deluxe pump is $210. The cost equation is:
Minimize Cost = 150x + 210y
b)
Hence the LP formation is:
Minimize Cost = 150x + 210y
4.5x + 3y ≤ 63
x + y ≤ 12
y ≥ 6
y ≤ 15
x ≥ 0.
c) The LP problem was solved using geogebra online graphing tool.
The points that satisfy the problem are:
(0, 6), (0,12), (6, 6)
At (0,6); cost = 150(0) + 210(6) = 1260
At (0,6); cost = 150(0) + 210(12) = 2520
At (6,6); cost = 150(6) + 210(6) = 2160
Hence the minimum cost is at (0, 6)

Answers
Answer:
a. – 4 or –3
b. –4 or –2
c. 4 or –3
d. 7 or 4
Step-by-step explanation:
To factorize the above expression, multiply the first and last term together, then find two factors of the result such that their sum will result to the middle term of the expression.
Now, we shall give the answers to the question.
a. x² + 7x + 12 = 0
x² + 3x + 4x + 12 = 0
Factorise
x(x + 3) + 4(x + 3) = 0
(x + 4)(x + 3) = 0
x + 4 = 0 or x + 3 = 0
x = 0 – 4 or x = 0 – 3
x = – 4 or –3
Therefore, the roots of the equation are – 4 or –3
b. t² + 6t + 8 = 0
t² + 2t + 4t + 8 = 0
Factorise
t(t + 2) + 4(t + 2) = 0
(t + 4)(t + 2) = 0
t + 4 = 0 or t + 2 = 0
t = 0 – 4 or t = 0 – 2
t = –4 or –2
Therefore, the roots of the equation are –4 or –2
c. 2n² – 2n – 24 = 0
Divide through by 2
n² – n – 12 = 0
n² + 3n – 4n – 12 = 0
Factorise
n(n + 3) – 4(n + 3) = 0
(n – 4)(n + 3) = 0
n – 4 = 0 or n + 3 = 0
n = 0 + 4 or n = 0 – 3
n = 4 or n = –3
Therefore, the roots of the equation are 4 or –3
d. y² – 11y + 28 = 0
y² – 4y – 7y + 28 = 0
Factorise
y(y – 4) – 7(y – 4) = 0
(y – 7)(y – 4) = 0
y – 7 = 0 or y – 4 = 0
y = 0 + 7 or y = 0 + 4
y = 7 or 4
Therefore, the roots of the equation are 7 or 4.

Step-by-step explanation:
Answer:
D=27 units, E=21 units, F=24 units
Step-by-step explanation:
The formula for area of a triangle is (BASE * HEIGHT)/2
For triangle D, the base is 9 units and the height is 6 units. Then you can apply the formula and do 9*6 which is 54 and then do 54/2 which is 27 units.
Similarly, the base for E is 6 units, and the height is 7 units. So you do 6*7 which is 42 and then do 42/2 which is 21 units.
Again, the base for F is 6 units, and the height is 8 units. Then again, using the formula, we can do 6*8 which is 48 and then do 48/2, which is 24 units.

Answer and Step-by-step explanation:
This problem involves the use of trigonometric functions.
First, we will use the tangent trig function, and then the sine trig function.
[tex]tan(32) = \frac{x}{15}[/tex]
We solve for x by multiplying both sides by 15.
15(tan(32)) = x
Put this into a calculator and solve.
x = 9.373
Now, we solve for y.
[tex]sin(32) = \frac{9.373}{y}[/tex]
We multiply by y on both sides first.
y(sin(32)) = 9.373
Now, we divide each side by sin(32).
[tex]y = \frac{9.373}{sin(32)}[/tex]
Put this into a calculator and solve.
y = 17.6877
x = 9.373
y = 17.6877

the perimeter of a playing field for a certain sport is 262 ft. the field is a rectangle and the length is 41 ft longer than the width. find the dimensions
Answers
Answer: The width of the playing field = 45 ft
length of playing fiels = 86ft
Step-by-step explanation:
Step 1
Perimeter of rectangular field is given as 2 ( L+ b)
Let the width be represented as x
such that the length = 41 ft longer than the width be x+ 41
To find the length and breadth
Step 2
Perimeter = 2( L+ b)= 2l + 2b
Perimeter = 2 (x+41 ) + 2 x = 262
2x + 82 + 2x= 262
4x+ 82= 262
4x= 262 - 82
4x= 180
x= 180/4
x= 45
width= 45 ft
length = x+ 41= 45+ 41= 86ft
