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.

Gagu is paid £1200 per month.
He is going to get a 4% increase in the amount of money he is paid.
Work out how much Gagu will be paid per month after the increase.
Answer:
£1248
Step-by-step explanation:
1200x4%
=£48
1200+48=£1248
Gagu will be paid £1248 after the increase.
The amount Gagu paid per month after the 4% increment is £1248
What is the method to calculate x% increment?If there is x% increment in y then the increment will be (x/100)*y and the new amount after x% increment will be now y + (x*y)/100
Given that Gagu is paid £1200 per month. He is going to get a 4% increase in the amount of money he is paid.
Initial payment = £1200
4% increment = 4% of initial pay = 4(1200)/ 100 = £ 48
After increment new payment = Initial payment + 4% increment = 1200+48
= £1248
Therefore, The amount Gagu paid per month after the increase is £1248

Alex opened a savings account with an initial deposit of $50. Each month, he deposits the same amount of money. He uses the equation t = 50 + 25m to determine t, the total amount of money in his savings account in m months. What is the unit rate and what is the meaning of the unit rate?
The unit rate is $25. The unit rate gives information on the amount by which the account increases per month.
What is the unit rate?The unit rate gives the amount by which the money in the account increases per month. It measures the rate of increase in the account.
In 1, month, the total value of the account would be: $50 + (25 x 1) = $75
In 2 months, the total value of the account would be: $50 + (25 x 2) = $100

Step-by-step explanation:
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.

What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Researching the function on the internet, it is found that:
When x = 0, y = -7, hence the y-intercept is of b = -7.When x increases by 1, y increases by 200, hence, the slope is of m = 200.Thus, the function is given by:
f(x) = 200x - 7.

3) Elliott is using cement circles to
create a walkway from his deck to his
driveway. One circle has an area of
200.96 inches. What is the radius of
one of the circles?
Answer: The radius is 8 inches
Step-by-step explanation:
The formula for the area of a circle is [tex]\pi r^2=A[/tex]
Where
A is the area (200.96 for this)
[tex]\pi[/tex] is pi (we'll round it to 3.14 for this)
and r is the radius
Let's sub in our values and solve for r
[tex]3.14r^2=200.96[/tex]
Divide both sides by 3.14 to isolate [tex]r^2[/tex]
[tex]\frac{3.14r^2}{3.14} =\frac{200.96}{3.14} \\\\r^2=64[/tex]
Take the square root of both sides to cancel the square
[tex]r^2=64\\\sqrt{r^2} =\sqrt{64} \\r=8[/tex]
