The nature of the roots of a given quadratic equation √3x²+10x+7√3=0 is real and distinct because of the value of b²-4ac>0.
where a, b, and c are the coefficients in the standard form of the quadratic equation ax²+bx+c=0
Given quadratic equation is √3x²+10x+7√3=0 on comparing with the standard form of a quadratic equation ax²+bx+c=0. Hence a=√3,b=10,
and c=7√3
Now b²-4ac=10²-4×√3×7√3=100-28×3=16>0.
here the value of b²-4ac is greater than 0.
We know if the value of b²-4ac then the roots of the given equations are real and distinct.

A piston rises to 5 cm and falls to 3 cm in such a way that it returns to the maximal height three times every two seconds. If we start observing the piston at its maximal height, find an equation modelling the height, h, t seconds from the initial observation.
Answer:
(1 cm)cos3πt
Step-by-step explanation:
Since the piston starts at its maximal height and returns to its maximal height three times evert 2 seconds, it is modelled by a cosine functions, since a cosine function starts at its maximum point. So, its height h = Acos2πft
where A = amplitude of the oscillation and f = frequency of oscillation and t = time of propagation of oscillation.
Now, since the piston rises in such a way that it returns to the maximal height three times every two seconds, its frequency, f = number of oscillations/time taken for oscillation where number of oscillations = 3 and time taken for oscillations = 2 s
So, f = 3/2 s =1.5 /s = 1.5 Hz
Also, since the the piston moves between 3 cm and 5 cm, the distance between its maximum displacement(crest) of 5 cm and minimum displacement(trough) of 3 cm is H = 5 cm - 3 cm = 2 cm. So its amplitude, A = H/2 = 2 cm/2 = 1 cm
h = Acos2πft
= (1 cm)cos2π(1.5Hz)t
= (1 cm)cos3πt
The diameter from the outer edge of the rubber of my old tires to the center of the tire is 76cm (30inches). What is the circumference of the tires?
Answer:
The circumference of the tires is of 94.25 inches.
Step-by-step explanation:
Circumference of a circle:
The circumference of a circle, with radius measuring r, is given by:
[tex]C = 2\pi r[/tex]
In which the radius is half the diameter.
In this question:
Diameter of 30 inches, so the radius is 30/2 = 15 inches.
The circumference is:
[tex]C = 2\pi (15) = 30\pi = 94.25[/tex]
The circumference of the tires is of 94.25 inches.

Have a good day!
Answer:
Value of x = -7
Step-by-step explanation:
Given:
First angle = 83°
Second angle = 24°
Third angle = (38 - 5x)°
Find:
Value of x
Computation:
We know that sum of all interior angle in triangle is 180°
So,
83 + 24 + 38 - 5x = 180
145 - 5x = 180
-5x = 35
x = -7
Value of x = -7

X-9/2=12
X=?
Find what does x equal to.
Answer:
x = 33
Step-by-step explanation:
cross-multiply:
x-9 = 2(12)
x-9 = 24
x = 33
Answer:
The answer is 33.
Step-by-step explanation:
1) Multiply both sides by 2.
[tex]x - 9 = 12 \times 2[/tex]
2) Simplify 12 × 2 to 24.
[tex]x - 9 = 24[/tex]
3) Add 9 to both sides.
[tex]x = 24 + 9[/tex]
4) Simplify 24 + 9 to 33.
[tex]x = 33[/tex]
Hence, the answer is 33.

Write an equation of the line that passes through the points (-2,-7) and (0,-4).
Answer:
Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] ) point - slope form of a line.
y = mx + b slope- intercept form of a line.
~~~~~~~~~~~~~~~~~
( - 2, - 7 )
( 0, - 4 )
m = [tex]\frac{- 4 - (-7)}{0 - (- 2)}[/tex] = [tex]\frac{3}{2}[/tex]
y - ( - 4 ) = [tex]\frac{3}{2}[/tex] ( x - 0 )
y + 4 = [tex]\frac{3}{2}[/tex] x
y = [tex]\frac{3}{2}[/tex] x - 4 slope- intercept form
3x - 2y = 8 standard form
