The provided quadratic equation, which has a negative discriminant value of -16, has no real number solutions.
What is the discriminant value in a quadratic equation?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]
In this equation,
If the discriminant value is positive (D>0), then the equation has 2 real solution.If the discriminant value is equal to zero (D=0), then the equation has 1 real solution.When the discriminant value is negative (D<0), then the equation has 2 imaginary solution.The quadratic equation given as,
[tex]0=ax^2 +bx +c[/tex]
This quadratic equation has a discriminant value of -16. As the value of discriminant is negative, thus it has no real solution.
Hence, the provided quadratic equation, which has a negative discriminant value of -16, has no real number solutions.

According to the question,
Time taken by Jesse to run 1 mile = 7 minutes
Also,
Time taken by Jesse to run 1 mile = 2½ minutes + Michael's time [tex]\;[/tex]
Now, we can say that :
⇒ 7 minutes = 2½ minutes + Michael's time
⇒ (7 - 2½) minutes = Michael's time
⇒ (7 - 5/2) minutes = Michael's time
⇒ (14 - 5)/2 minutes = Michael's time
⇒ 9/2 minutes = Michael's time
⇒ 4½ minutes = Michael's time [Answer]
Step-by-step explanation:
Question:-In track practice, Jesse ran a mile in 7 minutes. His mile time was2.5 minutes faster than Michael's time. Write and solve an equation to calculate Michael's mile time.
Solution
Jessie time 7 minute
Michael’s time is 2.5 times slower
Divide 7 minutes by 2.5 to get answer
Jesse = 7
Michael = 2.5 X
7 = 2.5 X
7/2.5 X = 17.5 to check answer divide 17.5 by the 2.5, your answer is 7.
Or if it was 2.5 more
we subtract 2.5 from 7
=> 7 - 2.5
=> 4.5
=> 4 ½

Which is the equation of a circle whose center is at the origin and that passes through the point (3, 5)?
Answer:
x² + y² = 34
Formula:
(x - h)² + (y - k)² = r² where (h, k) is the centerHere find the radius using distance formula: → origin : (0, 0)
√(x2-x1)²+(y2-y1)²√(3-0)²+(5-0)²√9+25√34Thus the equation of circle:
(x - 0)² + (y - 0)² = (√34)²(x - 0)² + (y - 0)² = 34x² + y² = 34Answer:
H. [tex]x^2+y^2=34[/tex]
Step-by-step explanation:
Equation of a circle (in standard form)
[tex](x-h)^2+(y-k)^2=r^2[/tex]
(where (h, k) is the center and r is the radius of the circle)
Given center = (0, 0):
[tex]\implies (x-0)^2+(y-0)^2=r^2[/tex]
[tex]\implies x^2+y^2=r^2[/tex]
As the circle passes through point (3, 5):
[tex]\implies 3^2+5^2=r^2[/tex]
[tex]\implies r^2=34[/tex]
Final equation
[tex]x^2+y^2=34[/tex]

3. Find the center of the circle that can be circumscribed about EFG with E(6,4), F(6,2), and G(10,2).
A. (6, 4)
B. (8,3)
C. (3,8)
D. (4,2)
Step-by-step explanation:
The general form of the equation of a circle is
(x-a)^2 + (y-b)^2 = r^2 where the center is (a,b)
Plugging in the given values:-
(6 - a)^2 + (4-b)^2 = r^2 and
(6-a)^2 + (2-b)^2 = r^2
Subtracting:-
(4-b)^2 - (2 - b)^2 = 0
16 - 8b + b^ - (4 -4b + b^2) = 0
12 - 4b = 0
-4b = -12
b = 3
Similarly if we take the 2 points (6,2) and G(10,2) and make two equations we can find the value of a
(6-a)^2 + (2-b)^2 = r^2
(10.a)^2 + (2-b)^2 = r^2 subtract::-
(6-a)^2 -(10-a(^2 = 0
this will give a = 8
so the center of the circle is the poit (8,3)

Answer:
1 cup
Step-by-step explanation:
8/6 times 3/4 = 1 cup -crispin
To serve 8 calls, 1 cup of sour cream is required.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that,
6 serve = 3/4 cup of sour cream
1 serve = (3/4×6) cup of sour cream
8 serve = (3/4×6)×8 cup of sour cream
8 serve = 1 cup of sour cream
Hence, to serve 8 calls, 1 cup of sour cream is required.

Use the function f(x) = x2 − 6x 3 and the graph of g(x) to determine the difference between the maximum value of g(x) and the minimum value of f(x). a parabola that opens down and passes through 0 comma 3, 3 comma 12, and 5 comma 8 3 6 12 18
A function assigns values. The difference between the maximum value of g(x) and the minimum value of f(x) is 18.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Since the maximum of the parabola function g(x) will lie at its vertex, therefore, the maximum will be at (3,12). Now, if we try to find the minimum of the function f(x). We need to plot the function on the graph as shown below.
As the minimum of the function f(x) will lie at the vertex of the parabola function, therefore the minimum of the function f(x) will lie at (3,-6).
If we try to find the difference between the maximum value of g(x) and the minimum value of f(x), then we will get,
[tex]\rm Difference=12-(-6)=18[/tex]
Thus, the difference between the maximum value of g(x) and the minimum value of f(x) is 18.

From the computation below, the area of the label is 707 Inches.
This calculation is carried out using the theorem of the area of curved shapes.
What is the Curved Surface Area of a Cylinder?The formula for the Curved Surface Area of a Cylinder is given as:
2 [tex]\pi[/tex] rh
= 2 [tex]\pi[/tex] x 7.5 x 15.
This assumes that the label also ends at an equal distance from the top of the lid. Hence 15in = 20 - (2.5 x2);
Recall that [tex]\pi[/tex] = 22/7, hence
= 2 x (22/7) x 7.5 x 15
= 707.142857143
Approximately, this equals; 707 Inches.
Hence, the area of the label = 707 inches.

Julie wants to randomly choose two out of three friends, Margarite, Anita, and Sasha, to go with her to a
concert. In which method does one of Julie's friends have more than a fair chance of being chosen?
Slip system can be used to give more than fair chances of selection where the number of slips for one is more than the other.
There are multiple ways of selecting random sample like tossing a coin, flipping a die, lottery system.
Describing a method which can be used to provide more than a fair chance of selection is as follows:
Julie has 3 friends, so make the total number of slips say n
where n is not a multiple of 3.
If n is not a multiple of 3 then her 3 friends will not get an equal chance of being selected.
Consider n=5
She has 3 friends, so 2 slips has repeated names, thus creating more chance of being selected than the one who has name only on one slip.
Thus, this method may result in more chance of selection of one over other.
