What value of x is in the solution set of 2x-3 > 11 - 5x?
Answers
Answer:
x ≤ 3
Step-by-step explanation:
Answer:
The value of x is 2.
Step-by-step explanation:
The key to this solution is to combine like terms.
2x-3 > 11-5x
There are lots of ways to combine them but the way I think would be the most simple would be to avoid negative numbers (although I personally enjoy it) but anyways,
First, you can add 5x to both sides of the inequality.
This would cancel out 5x and leave you with: 7x-3 > 11
The next terms that you can combine can be the constants. You can combine -3 and 11 and to do that, you add 3 on both sides. That would cancel 3 out and leave you with: 7x > 14
Now, the last step is to get x by itself and to do that, you divide 7 on both sides to get:
x > 2

For a dosage of x cubic centimeters (cc) of a certain drug, the resulting blood pressure B is approximated by the function below. Find the maximum blood pressure and the disage at which it occurs.
B(x)= 395x^2- 2370x^3, 0 <= x <= 0.16
a. The maximum is obtained for a dosage of __________________.
b. The maximum blood pressure obtained is ______________.
Answers
Answer:
A) Maximum for dosage is 0.11
B) maximum blood pressure = 1.625
Step-by-step explanation:
We are given the function;
B(x) = 395x² - 2370x³
To find maximum, we will find the derivative of the function and equate to zero.
B'(x) = 790x - 7110x²
Equating to zero gives;
790x - 7110x² = 0
790x = 7110x²
Dividing both sides by x gives;
790 = 7110x
x = 790/7110
x = 0.11
This falls in between the range of 0 <= x <= 0.16 given to us.
Therefore x = 0.11 is a maximum
Plugging this into B(x) = 395x² - 2370x³ gives;
B(0.11) = 395(0.11)² - 2370(0.11)³
B(0.11) = 1.625
Thus;
Maximum dosage is 0.11
maximum blood pressure = 1.625

Answers
Answer: The height of the building = 14.5 feet.
Step-by-step explanation:
Given: Length of ladder = 15 feet
Distance of base of ladder from building = 4 feet
Since building is standing vertical on ground making right angle.
So with ladder a right triangle is formed , where base = 4 feet , Hypotenuse = 15 feet [Hypotenuse is side opposite to right angle]
According to the Pythagoras theorem ,
Hypotenuse² = Perpendicular² + Base²
⇒ (15)² = Perpendicular² + (4)²
⇒ 225 = Perpendicular² +16
⇒ Perpendicular² = 225 -16
⇒ Perpendicular² = 209
⇒ Perpendicular = √209 = 14.4568322948 ≈ 14.5 feet
Hence, the height of the building = 14.5 feet.

b) needs parentheses: -1, (1±i√2)/3
Step-by-step explanation:
a) You can factor by grouping:
(x³ -2x²) -(5x -10) = x²(x -2) -5(x -2) = (x² -5)(x -2)
Roots are ±√5, 2.
__
b) The sum of odd-degree coefficients is equal to the sum of even-degree coefficients (3-1 = 1+1), so one root is x=-1. Factoring out that leaves the quadratic factor ...
3x³ +x² -x +1 = (x +1)(3x² -2x +1)
The quadratic formula can be used on the quadratic factor to find its roots:
x = (-(-2) ±√((-2)²-4(3)(1)))/(2(3)) = (2 ±√-8)/6 = (1 ±√-2)/3
Roots are -1, (1 ±i√2)/3.

Answers
Given :
A new car depreciates as soon as you drive it out of the parking lot. A certain car depreciates to half its original value in 4 years. If you bought a car 8 years ago and it is now worth $5,000.
To Find :
How much did you pay for the car originally.
Solution :
Let, original price is x.
It is given that price gets half after 4 years.
So, price after 8 year is, P = x/4 .
x/4 = 5,000
x = $20,000
Therefore, price of new of car is $20,000.
Hence, this is the required solution.

2). a(x) = 2x - x² If -6 < x ≤ 1

The radius of the base of a cylinder is increasing at a rate of 11 meter per hour and the height of the cylinder is decreasing at a rate of 44 meters per hour. At a certain instant, the base radius is 55 meters and the height is 88 meters. What is the rate of change of the volume of the cylinder at that instant (in cubic meters per hour)?
Answers
Answer:
The volume of the cylinder is decreasing at a rate of 83629.2 m³/h.
Step-by-step explanation:
The volume of a is given by:
[tex] V = \pi r^{2}h [/tex]
Where:
r: is the radius = 55 m
h: is the height = 88 m
We can express the rate of change of the volume of the cylinder as follows:
[tex] \frac{dV}{dt} = \pi[h\frac{2rdr}{dt} + r^{2}\frac{dh}{dt}] [/tex]
If dr/dt = 11 m/h and dh/dt = -44m/h, we have:
[tex] \frac{dV}{dt} = \pi[88 m*2*55 m*11 m/h + (55 m)^{2}*(-44 m/h)] = -83629.2 m^{3}/h [/tex]
Therefore, the volume of the cylinder is decreasing at a rate of 83629.2 m³/h.

The school received $ 55 on the second day selling 5 adult tickets and 2 student tickets. What is the price of each adult and student ticket?
Answers
9514 1404 393
Answer:
adult: $5student: $15Step-by-step explanation:
If we let 'a' represent the price of an adult ticket, and 's' represent the price of a student ticket, the two sales can be described by ...
5a +4s = 85
5a +2s = 55
Subtracting the second equation from the first gives ...
(5a +4s) -(5a +2s) = (85) -(55)
2s = 30 . . . . simplify
s = 15 . . . . divide by 2
Substituting this into the second equation, we have ...
5a +2(15) = 55
5a = 25 . . . . subtract 30
a = 5 . . . . . divide by 5
Each adult ticket sold for $5; each student ticket sold for $15.
At the city museum child admission is $5.40 and adult admission is $9.40. On Wednesday, 168 tickets were sold for a total sales of $1199.20. How many adult tickets were sold that day?
Answers
Given:
Selling price of child ticket = $5.40
Selling price of adult ticket = $9.40
Total tickets = 168
Total sales = $1199.20
To find:
The number of adult tickets sold.
Solution:
Let x be the number of child tickets and y be the number of adult tickets.
Total tickets : [tex]x+y=168[/tex] ...(i)
Total sales : [tex]5.40x+9.40y=1199.20[/tex] ...(ii)
From equation (i), we get
[tex]x=168-y[/tex]
Put this value in (ii).
[tex]5.40(168-y)+9.40y=1199.20[/tex]
[tex]907.2-5.40y+9.40y=1199.20[/tex]
[tex]4y=1199.20-907.2[/tex]
[tex]4y=292[/tex]
Divide both sides by 4.
[tex]y=\dfrac{292}{4}[/tex]
[tex]y=73[/tex]
Therefore, 73 adult tickets were sold that day.

The probability of college graduate getting employed within a year is 90 % 90%. The probability of a college graduate getting employed and buying a car within a year is 72 % 72%. What is probability that a college graduate bought a car within a year given that he got employed within a year?
Answers
Answer:
Step-by-step explanation:
Let the probability of getting employed after graduated within a year be P(A)
and the probability of buying a car within a year be P(B)
Given that:
The probability of getting employed after graduated within a year = 90% = 0.9
Then; Let that be P(A)
The probability of getting employed and buying a car within a year = 72% = 0.72.
Then; Let that be P(A∩ B).
The probability that a college student will get both events is P(B/A)
[tex]P(B/A) = \dfrac{P(A \cap B) }{P(A)}[/tex]
[tex]P(B/A) = \dfrac{0.72}{0.90}[/tex]
P(B/A) = 0.80
