Equation 3x2 + 2x + 1 = 0's discriminant is -8.
D = b2 - 4ac is the quadratic equation's discriminant.
where a, b, and c are the coefficients of the equation in the form ax² + bx + c = 0.
Therefore,
D = b² - 4ac
= 2² - 4(3)(1)
= -8
The discriminant of a quadratic equation is found by using the formula D = b² - 4ac, where a, b, and c are the coefficients of the equation in the form ax² + bx + c = 0. In this case, a = 3, b = 2, and c = 1, so the discriminant would be D = b² - 4ac = 2² - 4(3)(1) = -8.

how do i find the surface area and volume of this shape?
Answer:
3,761.46 m³
Step-by-step explanation:
Volume of a cone = 1/3πr²h
π = 3.14
radius, r = diameter/2
= 25/2 = 12.5 m
Height, h = 23m
Volume of a cone = 1/3πr²h
= 1/3 * 3.14 * 12.5² * 23
= 1/3 * 3.14 * 156.25 * 23
= 11,284.375 / 3
= 3761.4583333333
Approximately,
Volume of the cone = 3,761.46 m³
Todd plans to run at least 5 miles each week for his health. has a circular route in the neighborhood to run. Once around that route is 420 yards. If runs that route 30 times during the week, will he cover at least 5 miles? Explain.
Answer: Yes
Step-by-step explanation:
Given
Once around park measures 420 yards
Todd needs to complete 5 miles
He runs 30 times during the week
We know, [tex]1\ mile=1760\ yards[/tex]
for 30 rounds, distance is
[tex]\Rightarrow 30\times 420=12,600\ \text{yards}[/tex]
In miles, it is
[tex]\Rightarrow 12,600\equiv \dfrac{12,600}{1760}\\\Rightarrow 7.159\approx 7.16\ \text{miles}[/tex]
As he runs more than the target. Therefore, he completed his target of 5 miles.

a system of equations is shown below 7x + 3y= 22. 3x - 3y =18 what is the solution to the system of equations
4,-2
distribute and combine like terms
Answer:
(4, -2)
Step-by-step explanation:
7x+3y= 22
3x-3y= 18
Add them in vertical columns. 7x + 3x = 10x. The 3y and the -3y cancel each other out. 22+ 18 = 40.
You're left with 10x = 40. Solve for x by dividing both sides by 10
x = 4
Plug in 4 into any of the original equations and solve for y.
7(4) + 3y =22.
28 + 3y =22
Subtract 28 on both sides
You're let with 3y = -6. Solve for y by dividing both sides by 3
y= -2
Put it together in coordinate point form. (4, -2)

Answer:
[tex]50.04[/tex]
Step-by-step explanation:
Use this formula for arc length
[tex]2\pi \times r( \frac{x}{360} )[/tex]
where r is the radius and x is the arc measure.
We know Arc de is 8.73 so we are finding x.
R equal 10.
[tex]2\pi \times 10( \frac{x}{360} ) = 8.73[/tex]
[tex]20\pi( \frac{x}{360} ) = 8.73[/tex]
[tex]20\pi \times x = 3142.8[/tex]
[tex]x = \frac{3142.8}{20\pi} [/tex]
x=50.04
The value of the angle will be 50.04.
What will be the angle?It is given in the question that
The arc of the circle A=8.73 In
The radius of the circle =10 In
Now from the formula of arc
[tex]A=2\pi r(\dfrac{\theta}{360} )[/tex]
[tex]8.73=2\pi 10\times \dfrac{\theta }{360}[/tex]
[tex]\theta = \dfrac{8.73\times 360 }{ 2\pi\times 10} =50.04[/tex]
[tex]\theta=50.04[/tex]
Thus the value of the angle will be 50.04

Answer:
DF = 75°FBE = 105°FC = 60°CBE = 45°DAC = 225°ABE = 135°AFE = 225°ABF = 120°Step-by-step explanation:
AC and DE are diameters, so divide the circle into equal portions that have a total angle measure of 180°.
angle ABD = 180° -angle DBF - angle FBC = 180° -75° -60°
angle ABD = 45°
angle CBE is a vertical angle to angle ABD, so has the same measure, 45°.
angle ABE is supplementary to angle CBE, so has measure 180° -45° = 135°. Long arc AE is 360° less this value, so is 360° -135° = 225°. Vertical angle DBC has the same measure as angle ABE, so long arc DAE will also be 225°.
angles FBC and CDE add to make angle FBE, so that angle is ...
angle FBE = 60° +45° = 105°
