Use Vieta's Theorem to solve the problems. The difference of the two solutions of x2+19x+c=0 is 15. Find c.
The value of c from the given equation is 34.
What is the solution of a quadratic equation?The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.
The given equation is x²+19x+c=0
Vieta's Theorem is If f(x) = ax² + bx + c is a quadratic equation with roots α and β then,
Sum of roots = α + β = -b/a
(x + a) (x + b) = x² + (a + b) x + ab
a + b = 19
a - b = 15
a = 17
b = 2
c = ab = 34
Therefore, the value of c from the given equation is 34.

Using Vieta's Theorem, the difference of the roots was used to set up two equations. Solving them simultaneously gave us the individual roots, which were then multiplied to find the required product, c, which is 34.
Explanation:To solve for c in the quadratic equation x^2 + 19x + c = 0 using Vieta's Theorem, we need to find the two roots of the equation and their relationship to the coefficients.
According to Vieta's formulas, for a quadratic equation of the form ax^2 + bx + c = 0, the sum of the roots -b/a and the product of the roots c/a. Since the coefficient a is 1 in our equation (x^2 + 19x + c = 0), the sum of the roots is -19, and the product is c.
We are told the difference of the two roots is 15. Let's denote the larger root as r1 and the smaller one as r2. Thus, r1 - r2 = 15. But we also know that r1 + r2 = -19 (the negative coefficient of x).
We can now set up two equations:
r1 + r2 = -19r1 - r2 = 15By solving these two equations simultaneously, we add them together to eliminate r2:
2r1 = -4
r1 = -2
Substitute r1 back into one of the original equations to find r2:
r1 + r2 = -19
-2 + r2 = -19
r2 = -17
Now, we use the product of the roots to find c:
c = r1 * r2
c = -2 * -17
c = 34
Therefore, the value of c in the quadratic equation is 34.

Answer:
Step-by-step explanation:
The domain of a function simply encompasses the set of input values which satisfies a given function. Hence, the values within the domain of the function are ; - 6, - 4, - 2, 4
Since the domain marks the set of input values, then they could be described as the x - values which satisfies the condition on the graph. The line on the right covers x - values greater than 2.

Mary takes 9 grapes from rohin and then decides to give 4 back draw a model for the subtraction problem using integer chips
To draw an integer chips model for the subtraction problem, first draw nine positive chips to represent the grapes Mary took, then draw four negative chips for the grapes she gave back. Subtract the negative from the positive chips to get the final answer.
Explanation:In this integer subtraction problem, you would first draw 9 positive chips, symbolizing the 9 grapes Mary initially received from Rohin. Positive chips can be represented by circles or squares. You could use different colors, such as blue for positive (or grapes Mary has).
Next, to represent the 4 grapes that Mary returned to Rohin, you would draw 4 negative chips. Negative chips (or the grapes Mary gave back) could be represented by a different color, such as red.
Subtracting 4 from 9, we then remove 4 positive chips from the model, leaving five positive chips, representing the 5 grapes Mary has left after she returned 4 to Rohin.

The circumference of a circle is 270.04 centimeters. What is the circle's diameter?
Use 3.14 for .
Answer:
86 cm
Step-by-step explanation:
An object's dimensions are: length of 25cm, wight of 10cm, and height of 15cm. calculate the object's density if its mass is 3000g
Density = Mass / Volume
The volume is length * width * height, which equals 25 * 10 * 15, making it 3750 cm^3.
Mass / Volume = 3000 g / 3750 cm^3 = 0.8 g/cm^3
Answer:
Density = Mass / Volume
The volume is length * width * height, which equals 25 * 10 * 15, making it 3750 cm^3.

Answer:
42ft
Step-by-step explanation:
Area of a triangle = 1/2 * base * height
So that little triangle section:
1/2 * 2 * 3 = 1/2 * 6 = 3
Now we do the rectangle Section:
Area of a rectangle = length * width
So that rectangle is 3 * 7 = 21
If you eliminate those two shapes, you are left with a trapezoid.
Area of a trapezoid is 1/2 * (base 1 + base 2) * height
Base 1 is 3 which is the width of the rectangle.
Base 2 is the 6.
The height is the given 11 feet subtracted by the 7 feet from the length of the rectangle which is 4.
Plug all this in to the formula you get 1/2 * (6 + 3) * 4 = 1/2 * 9 * 4 = 1/2 * 36 = 18.
Now add all of your areas together;
21 + 3 + 18 = 24 + 18 = 42
Answer:
Area=42 ft.²
Step-by-step explanation:
This is an area problem. But since there are multiple shapes (2 triangles and a rectangle) we have to split the shapes and work each one separately. First we will start on the far right, with the small triangle. This one is the easiest one since the line is already drawn to separate it from the rest of the shape.
Area of a triangle=1/2 bh
A=1/2(2x3)
A=1/2(6)
A=3
The next shape is the the rectangle in the middle. Looking at the first image, I've drawn a line across the bottom, we need to find the area of that new image, the width is 3 ft and the length is 11 ft.
Area of a rectangle=lw
A=(11x3)
A=33
Finally, we need to find the area of the last triangle. Looking at the second image, I've add the correct base and height, 4 and 3. So now we need to use the triangle formula and solve
Area of a triangle=1/2bh
A=1/2(4x3)
A=1/2(12)
A=6
Now we can add the three areas together and get the total area:
3+33+6=42 ft

Step-by-step explanation:
g(a) = a² + 2a
g(x) - g(a) = x² + 2x - a² - 2a
= x² - a² + 2x - 2a
= (x - a)(x + a) + 2(x - a)
= (x - a)(x + a + 2)
[g(x) - g(a)] ÷ (x - a)

The diameter of a circle is 28 inches what is the circle's area?
use 3.14 for pi
Answer:
615.75216....
Step-by-step explanation:
The formula is A = π * (ø/ 2)^2
A = Circle area
π = Pi = 3.14
ø = Circle diameter
A= 3.14 (28/2)^2
Answer:
Area = 615.44 inches
Step-by-step explanation:
Diameter = 2 * radius
28 = 2 * radius
Divide both sides of the equation by 2
14 = radius
Find area
A = π r²
A = 3.14 (14)²
A = 3.14 (196)
A = 615.44

Question 2: You want to donate 30% of the $400 earned at your yard sale to
charity. How much should you donate?
What is 10% of the total?
Your answer
What will 30% be?
Your answer
Answer:
10%= 40$ 30%=120$
Step-by-step explanation:
ok so u earn 400$ at a yard sale. you divide it by 100 400/100=4. ok so then you multiply four by 10=40 and that is 10% multiply it by 30 u get 120 or 30%
sorry for the bad spelling
To find out how much to donate, you need to understand what percentage means. 10% of $400 is $40 and since 30% is 3 times as much, you should donate $120.
Explanation:To solve this problem, you first need to understand what 10% of a quantity means. 10% of a quantity is simply that quantity divided by 10. If you want to donate 30% of the $400 earned at your yard sale to charity, you first need to find 10% of $400, which is $400 divided by 10. This gives you $40.
Since 30% is the same as three times 10%, you just need to multiply your answer for 10% by 3. Therefore, you should donate $40 times 3, which equals $120.
