Answer:

If Discriminant,b^{2} -4ac >0

Then it has Two Real Solutions.

Step-by-step explanation:

To Find:

If discriminant (b^2 -4ac>0) how many real solutions

Solution:

Consider a Quadratic Equation in General Form as

ax^{2} +bx+c=0

then,

b^{2} -4ac is called as Discriminant.

So,

If Discriminant,b^{2} -4ac >0

Then it has Two Real Solutions.

If Discriminant,b^{2} -4ac < 0

Then it has Two Imaginary Solutions.

If Discriminant,b^{2} -4ac=0

Then it has Two Equal and Real Solutions.

zlopas [31]

Answer:

Domain = \{9, 10, 11, 12\}

Range = \{22, 32, 41, 30\}

Step-by-step explanation:

Given

Grade 9: 22

Grade 10: 32

Grade 11: 41

Grade 12: 30

Required

Determine the domain and the range

The domain and range of a function is represented as thus (x,y)

From the given parameters;

(x,y) = (Grade\ 9, 22), (Grade\ 10, 32) (Grade\ 11, 41), (Grade\ 12, 30)

Remove "Grade" to represent as only digits

(x,y) = (9, 22), (10, 32), (11, 41), (12, 30)

Split to x and y values:

<em>Where x = domain and y = range</em>

Domain = \{9, 10, 11, 12\}

Range = \{22, 32, 41, 30\}

<em>So, from the list of given options; option C answers the question.</em>

3<br>Which is an asymptote of the graph of the function Y = tan(3/4x)​
azamat

Answer:

2)x=-2π/3

Step-by-step explanation:

The following options are missing:

<em>1)x=-4π/3 </em>

<em>2)x=-2π/3 </em>

<em>3)x=3π/4 </em>

<em>4)x=3π/2</em>

<em />

The trigonometric function tan(x) has asymptotes at x = π/2 radian and x = -π/2 radian. Therefore, tan(3/4x) would have asymptotes at:

3/4x = π/2

x = π/2*4/3

x = 2π/3

or

3/4x = -π/2

x = -π/2*4/3

x = -2π/3

Delvig [45]

Answer:

Circumfrence: 40.21

Radius: 6.4

Step-by-step explanation:

For radius, you only have to divide the diameter (in this case 12.8) by 2 which gives us 6.4

For Circumference, plug in the radius in the formula C=2π(6.4), and that gives us 40.21
