Which of the following is the nature of the roots of the quadratic equation if the value of its discriminant is positive and a perfect square?A. The roots are not real.B. The roots are rational and equal.C. The roots are irrational and not equal.D. The roots are rational and not equal.

Answers

Answer 1

D) if the value of its discriminant is positive and a perfect square the   The roots are rational and not equal.

Nature of roots of quadratic equation:

b2 – 4ac > 0  Real and the value of roots are unequal

b2 – 4ac = 0  Real and value of roots are  equal

b2 – 4ac < 0 Distinct and Imaginary roots

b2 – 4ac > 0 (is a perfect square)  Real, rational and value of roots are Distinct

These are the four conditon for the nature of root and the condition which is driving force for the loop .

so form the above statement conditon 4 satisfies and hence the quadratic equation have real rational and distinct or not equal root.

What in a region can be affected by latitude, topography, altitude and closeness to a large body of water, jet streams and surface currents?

Answers

Answer:

Hey!

Step-by-step explanation:

Latitude, or how far one is from the equator, greatly affects the climate and weather of an area. If you live close to the equator, the climate will be warmer, while moving north or south from the equator brings a cooler climate. Altitude, or how high one is above sea level, has a similar effect–the higher the elevation, the colder the climate.

Hope this helps! :)

what is a point-slope equation of the line with slope -12 that goes through the point (5,3)?
A. y + 3 = 12 ( x + 5)
B. y - 3 = -12 ( x -5 )
C. y - 3 = 12 ( x - 5)
D. y + 3 = -12 ( x + 5 )

Answers

the answer should be either B or D im not sure on the graphing part but both B and D equal -12

Step-by-step explanation:

Equation of a straight line is given by Y=MX+C

GIVEN POINTS (5, 3) and gradient -12, therefore

in the form of y=mx+c to get the constant, it will be 3=-12(5)+c

3=-60+c

3+60=c

c=63

y=mx+c

y=-12x+63

y- intercept = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Given

f(x) = [tex]\frac{1}{2}[/tex] [tex](6)^{x}[/tex]

To find the y- intercept let x = 0 , then

f(0) = [tex]\frac{1}{2}[/tex] [tex](6)^{0}[/tex] [ [tex]6^{0}[/tex] = 1 ]

      = [tex]\frac{1}{2}[/tex] × 1 = [tex]\frac{1}{2}[/tex] ← y- intercept

A party cap is in the form of a frustum. The radii of its ends are 10cm and 30 cm. The volume of the cap is 9100. What is the height of the cap?

Answers

Answer:

4.46cm

Step-by-step explanation:

Volume of a frustum is expressed as;

V = (1/3) * π * h * (r₁² + r₂² + (r₁* r₂))

h is the height of the frustum

r₁ and r₂ are the radii of its ends

V is the volume

Given

V = 9100cm₃

r₁ = 10cm

r₂ = 30cm

Substitute

9100 = (1/3) * (3.14) * h * (10² + 30² + (10* 30))

9100 = 1/2(3.14)*h*(100+900+300)

9100 = 1.57*h*(1300)

9100 = 2,041h

h = 9100/2,041

h = 4.46cm

Hence the height of the cap is 4.46cm

A car dealership sells sedans and SUVs. In 2000, the ratio in which they were sold was 5:4. By 2010, the dealership had adjusted its inventory to a 2:7 ratio. If it sold 84 SUVs in 2010, how many sedans did it sell in 2000?

Answers

Answer:

60 sedans

Step-by-step explanation:

The computation of the number of sedans sold in 2000 is given below:

Given that

The ratio of sedans and SUV is 5:4

And, in 2010 its ratio is 2:7

Now in 2010, 84 SUVs sold

So

84 SUVS = 7

For total 9, it would be

= 84 × 9 ÷  7

= 108 vehicles

Now the number of sedans is

= 108 × 5 ÷ 9

= 60 sedans
