Write a program that will solve a quadratic equation: ax2 + bx + c = 0. The program must ask the user to enter the values for a, b and c. It should then determine the discriminant of the parabola and based on the discriminant it should display the real roots: Discriminant = b2 - 4ac > 0 means there will be two distinct real roots. Discriminant = b2 - 4ac = 0 means there will be only one real root. Discriminant = b2 - 4ac < 0 means there will be no real roots. Use the if - then else structure in your program to decide the outcome of the program. User must then use the quadratic equation to solve for x: = − ± √ −
Answer:
x= -b ±√b²- 4ac/2a
Step-by-step explanation:
ax2 + bx + c = 0
Dividing the quadratic equation by a gives
x2 + b/ax + c/a = 0
x2 + b/ax = - c/a
Applying the square formula
(x)^2 + 2(x) (b/2a) + (b/2a)^2= + (b/2a)^2- c/a
(x+b/2a)^2= b²/4a² - c/a
(x+b/2a)^2= b²/4a² - 4ac/4a²
(x+b/2a)^2= b²- 4ac/4a²
Taking square root of both sides gives
(x+b/2a)= ±√b²- 4ac/2a
x= -b/2a±√b²- 4ac/2a
x= -b ±√b²- 4ac/2a
This is called the quadratic formula and it can solve the value for x for the given value of a, b and c for the quadratic equation.
From this it is concluded that
Discriminant = b2 - 4ac > 0 means there will be two distinct real roots. Discriminant = b2 - 4ac = 0 means there will be only one real root. Discriminant = b2 - 4ac < 0 means there will be no real roots.
This is because a square root of a value greater than 0 is possible and gives two values for roots of x.
The square root of a value less than 0 gives a negative number and therefore the roots are an imaginary number.
The square root of a value greater equal to 0 gives a zero leaving behind only one real root.

the question is 7a + 10 = 2a
Answer:
a = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 - 10 = 2a - 10
Simplify:
7a = 2a - 10
Subtract 2a from both sides:
7a - 2a = 2a - 10 - 2a
Simplify:
5a = -10
Divide both sides by 5 and simplify:
a = -2
Answer:
A = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 = 2a -10
Simplify the expression, 7a = 2a - 10
Subtract 2a from both sides next
7a - 2a = 2a - 10 - 2a
Subtract 7a - 2a
5a = -10
5a / 5 = -10/5
a = -2

Triangle EFG has vertices E(-3,1), F(1,1), and G (4,5). Find the coordinates of the image of point F after a reflection across the x-axis.
Answer:
(1,-1)
Step-by-step explanation:
the coordinates of the image of point F after a reflection across the x-axis is (1,-1).
What is reflection?In mathematics, a reflection (also spelled reflexion) is a mapping from a Euclidean space to itself that is an isometry with a hyper plane as a set of fixed.
Here, given that,
Triangle EFG has vertices E(-3,1), F(1,1), and G (4,5).
We have to find the coordinates of the image of point F after a reflection across the x-axis.
Now, we know that,
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.
Hence, the coordinates of the image of point F after a reflection across the x-axis is (1,-1).

The _______________________ is a ray that divides an angle into 2 congruent angles.
Answer:
Angle bisector
Step-by-step explanation:
A bisector cuts a line into two even parts, therefore an angle bisector would split an angle into two congruent angles, each that have exactly half the measure of the original angle.

A triangle has side lengths of (1.2u+1.8v)(1.2u+1.8v) centimeters, (6.5u+8.7w)(6.5u+8.7w) centimeters, and (5.8w-6.9v)(5.8w−6.9v) centimeters. Which expression represents the perimeter, in centimeters, of the triangle? 13.5uw+3.6vw13.5uw+3.6vw 7.7u+1.8w+7.6v7.7u+1.8w+7.6v -1.1vw+15.2uw+3uv−1.1vw+15.2uw+3uv 14.5w-5.1v+7.7u14.5w−5.1v+7.7u
Answer:
7.7u - 5.1v + 14.5w
Step-by-step explanation:
Given length:
Side A = (1.2u+1.8v) centimeters,
Side B = (6.5u+8.7w) centimeters
Side C = (5.8w-6.9v) centimeters
Perimeter of a triangle = side A + side B + side C
= (1.2u+1.8v) + (6.5u+8.7w) + (5.8w-6.9v)
= 1.2u + 1.8v + 6.5u + 8.7w + 5.8w - 6.9v
Collect like terms
= 1.2u + 6.5u + 1.8v - 6.9v + 8.7w + 5.8w
= 7.7u - 5.1v + 14.5w
Therefore, the perimeter of the triangle is 7.7u - 5.1v + 14.5w

Ainsley walks 3/5 mile in 1/3 of a day. Sarah walks 5/8 mile in 2/6 of a day. Who walked farther, Ainsley or Sarah? Find the unit rate for each girl and then tell who you think walked farther with the correct unit rate given below. *
[tex]Ainsley \: walked \: in \: \frac{1}{3} \: \: of \: a \: day \ \: = \frac{3}{5} mile[/tex]
[tex] = \frac{1}{3} \times 24 = \frac{3}{5} [/tex]
[tex]8 \: hours = \frac{3}{5} \: miles[/tex]
[tex]Sarah \: walked \: in \: \frac{2}{6} of \: a \: day \: = \frac{5}{8} miles[/tex]
[tex] \frac{2}{6} \times 24 = \frac{5}{8} [/tex]
[tex]8 \: hours \: = \frac{5}{8} \: miles[/tex]
Let us see who walked more :
[tex]Ainsley \: walked \: = \frac{3 \times 8}{40} [/tex]
[tex] = \frac{24}{40} \: miles[/tex]
[tex]Sarah \: walked \: = \frac{5 \times 5}{40} [/tex]
[tex] = \frac{25}{40} \: miles[/tex]
[tex] \frac{24}{40} < \frac{25}{40} [/tex]
Sarah walked farther than Ainsley .
[tex] \frac{25}{40} - \frac{24}{40} = \frac{1}{40} \: miles[/tex]
∴ Sarah walked farther than Ainsley by 1/40 miles .

The simplified form of the expression (2x^2+4−x^3)+(−4x^2+6x^3−2) in standard form is -2x^3 + 2x^2 + 2.
What is an expression?
An expression is a mathematical phrase that can contain numbers, variables, and operators. It represents a value or a calculation, but it is not simplified to a single value.
To simplify the expression (2x^2+4−x^3)+(−4x^2+6x^3−2) in the standard form, we can combine like terms and apply the order of operations.
Step 1: Add and subtract the terms inside the first set of parentheses:
2x^2 + 4 - x^3 + (-4x^2 + 6x^3 - 2)
Step 2: Combine like terms:
-2x^3 + 2x^2 + 4 - 2
Step 3: Rearrange the terms in standard form, which is the form with the variable with the highest exponent first, and the numerical constant last:
-2x^3 + 2x^2 - 2 + 4
Step 4: Combine the constant terms:
-2x^3 + 2x^2 + 2
Hence, The simplified form of the expression (2x^2+4−x^3)+(−4x^2+6x^3−2) in standard form is -2x^3 + 2x^2 + 2.
