Consider the function f(x) = 3x2 7x 2. what is the value of the discriminant? how many x-intercepts does this function have? what are the number of zeros for this function?
The value of the discriminant is 25, there are 2 x-intercepts does this function have and the 2 number of zeros for this function has.
How to find the value of discriminant?The standard form of the quadratic equation is,
[tex]ax^2+bx+c=0[/tex]
Here,(a,b, c) is the real numbers and (x) is the variable.
For this equation, the discriminant value can be given as,
[tex]D=b^2-4ac[/tex]
The given quadratic function is,
[tex]f(x) = 3x^2 +7x+ 2[/tex]
Compare it with standard form, we get,
[tex]a=3\\b=7\\c=2[/tex]
Thus, the value of discriminant is,
[tex]D=(7)^2-4(3)(2)D=49-24\\D=25[/tex]
The value of discriminant is positive. Thus, the quadratic equation has two real solution and 2 zeros.
Hence, the value of the discriminant is 25, there are 2 x-intercepts does this function have and the 2 number of zeros for this function has.

6.5 inches
39 inches
Answer:
6.5 inches
Step-by-step explanation:
Finding the height of the cylinder
Volume = 936 π in³
diameter = 24 inches
r = 24 ÷ 2
r = 12 inches
Volume = 936π
πr²h = 936π
[tex]\bf \sf h= \dfrac{936 \pi }{r^2*\pi }\\\\h = \dfrac{936 * \pi}{12*12* \pi}\\\\h = \dfrac{936}{12*12}\\\\\\\boxed{height = 6.5 \ inches}[/tex]

1. Mrs. Rodger got a weekly raise of $145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
weekly raise= $145
to find:an integer describing how the raise will affect her paycheck.
solution:Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of $ 145.
So after completing the 1st week she will get $ (x+145).
Similarly after completing the 2nd week she will get $ (x + 145) + $ 145.
= $ (x + 145 + 145)
= $ (x + 290)
therefore, in this way end of every week her salary will increase by $ 145.

Answer:
CA ≈ 10 cm
Step-by-step explanation:
Since we know 2 sides and 1 angle we can use the Law of Cosine to find the third side.
CA = √(AB²+CB²- 2· AB· CB· cos 50°)
CA = √(7² +13² -2·7·13· cos 50°)
CA = √(49 +169 -116.987345)
CA = √101.012655
CA = 10.0505
CA ≈ 10 cm

I need this by today please explain it clearly and also say the equation, Thank you (:
Answer:
1. x - 12 = 14 {brother's age minus 12 equals sister's age}
x = 26 {added 12 to each side}
Your brother is 26.
2. x+8.95=21.35
now you must subtract 8.95 by both sides which equals x =12.4
3. 29 compact cars.
The total number of vehicle is 37. So you can just subtract 37 by 8 which gives 29.
4. x +73=95
subtract both sides by 73. which equals 22
5. $160 He originally spent $123.45 and was left with $36.55 you just add both numbers and that's what you get altogether.
6. X-225=548
Solve for x
Add 225 to both sides. So x - 753

The mountain in "The Negro Artist and the Racial Mountain" is considered as an obstacle for Negro artists who wish for others to recognize their work. This isn't just part of their job, but it's part of a racial dispute because of their color. Langston Hughes, the author, describes these Negro artists as very talented people. These are also people who believe they can make it big as artists, but they wish to be white to do so. Black artists think they can't be accepted as people, let alone artists. So the mountain in the essay represents a huge obstacle these people have to achieve. That obstacle is being accepted by everyone else, and that includes them looking past their color before appreciating their art.

The price of a bus ticket to Saskatoon is $180. This bus has 56 seats. The bus company is considering dropping this bus fare as part of a promotion to increase the ridership on that route.
The buses has only been at half capacity lately. The companies research shows that for every 5$ decreases they will gain 2 more riders.
1. Define variable and set up an equation to represent his scenario
2. What is the maximum revenue the bus company can earn and what will be the cost of a ticket when the revenue is at a maximum
The bus tickets and price are illustrations of a quadratic function, and the maximum revenue the bus company can earn is $5107.6
The variables of the scenarioThe variable representation used in this scenario are:
Let x represents the number of seatsLet y represents the total amountThe maximum revenueThe price is given as:
Price = $156
The number of seats is given as:
Seats = 56
When the bus is at half capacity, we have:
Seats = 28
As the price decreases by $5, the rider gains 2 more.
So, the revenue equation is:
y = (156 - 5x)(28 + 2x)
Expand
y = 4368 - 140x + 312x - 10x²
Differentiate
y' = 0 - 140 + 312 - 20x
Evaluate the sum
y' = 172 - 20x
Equate to 0
172 - 20x =0
Add 20x to both sides
20x = 172
Divide both sides by 20
x = 8.6
Substitute x = 8.6 in y = (156 - 5x)(28 + 2x)
y = (156 - 5 * 8.6)(28 + 2 * 8.6)
Evaluate
y = 5107.6
Hence, the maximum revenue the bus company can earn is $5107.6
