Find the values of P for which the quadratic equation 4x²+px+3=0 , provided that roots are equal or discriminant is zero .

Let us Consider a quadratic equation αx² + βx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.

For equal roots

[tex]\quad\green{ \underline { \boxed{ \sf{Discriminant, D = β² - 4αc}}}} [/tex]

So,

[tex]\sf{ β² - 4αc = 0}[/tex]

Here,

Now,

[tex]\begin{gathered}\implies\quad \sf p²- 4 \times 4 \times 3 =0 \end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \sf p²- 48 =0 \end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \sf p²=48\end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \sf p=±\sqrt{48}\end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \sf p=±\sqrt{2 \times 2 \times 2 \times 2 \times 3} \end{gathered}[/tex]

[tex]\begin{gathered}\implies\quad \sf p=± 2\times 2\sqrt{ 3 }\end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \boxed{\sf{p=±4\sqrt{ 3 }}}\end{gathered} [/tex]

Thus, the values of P for which the quadratic equation 4x²+px+3=0 are-

4√3 and -4√3.

Answer: [tex]y=\frac{3}{17}x-13[/tex]

Step-by-step explanation:

Find the slope of the line between (-17, -16) and (0,-13) using [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], the change of y over the change of x

[tex]m=\frac{3}{17}[/tex]

Use the slope and a given point to substitute for [tex]x_{1}[/tex] and [tex]y_{1}[/tex] in the point-slope form [tex]y-y_{1} =m(x-x_{1} )[/tex].

[tex]y-(-16)=\frac{3}{17}(x+17)[/tex]

Solve for y and rewrite into [tex]y=mx+b[/tex]

[tex]y=\frac{3}{17}x-13[/tex]

Answer:

Step-by-step explanation:

The absolute value function multiplies its argument by -1 if and only if that argument is negative.

  [tex]|x-120|=\begin{cases}-(x-120)&\text{for }(x-120) < 0\\(x-120&\text{for }(x-120)\ge0\end{cases}[/tex]

The first condition resolves to ...

  x -120 < 0   ⇒   x < 120 . . . . . matches the given condition x < -120

So, we can simplify the expression to ...

  -(x -120) = 120 -x . . . when x < -120

__

  [tex]|x-(-12)|=\begin{cases}-(x+12)&\text{for }(x+12) < 0\\(x+12)&\text{for }(x+12)\ge0\end{cases}[/tex]

The second condition resolves to ...

  x+12 ≥ 0   ⇒   x ≥ -12 . . . . . matches the given condition x > -12

So, we can simplify the expression to ...

  x +12 . . . when x > -12

_____

Additional comment

You may have noticed that the function |x -120| translates the absolute value function 120 units to the right. The condition x < -120 puts the boundary at 120 unit to the left of 0, well within the area to the left of the vertex. This is illustrated by the attached graph.

[tex]m\angle X = m\angle Z[/tex] (Opposite angles of a parallelogram)

[tex]\implies m\angle X = 70\degree[/tex]

In [tex]\triangle WXY[/tex]

WX = XY (given)

(Angles opposite to equal sides are equal)

[tex]m\angle XWY = x [/tex] (Given)

[tex]\implies m\angle XYW=x[/tex]

[tex]\implies x + x + 70\degree=180\degree[/tex]

(By angle sum postulate of a triangle)

[tex]\implies 2x =180\degree-70\degree[/tex]

Hello!

This is a parallelogram. It is a quadrilateral with two pairs of parallel sides. Here, the opposite angles are alternate, that is, they have togheter 180°.

Rhombus

This is a rhombus. It is a quadrilateral whose four sides all have the same length. Here, the diagonals of a rhombus intersect at equal angles.

A rhombus has opposite angles equal and the figure formed by joining the midpoints of the sides of a rhombus is a rectangle, and vice versa. It has an inscribed circle.

Good luck:)

Explanation:

The notation

P( Take the bus | Junior)

is the same as writing

P( Take the bus given Junior)

I replaced the vertical bar with the word "given".

Since we're given that the person is a Junior, this means we only focus on the Juniors. There are 13+20+2 = 35 Juniors and 20 of them take the bus.

20/35 = 0.5714 approximately which rounds to 0.57

This says about 57% of the Juniors take the bus.

The probability of P(take the bus/Juniors)  is 0.57 or in percentage is 57%.

It is a branch of mathematics that deals with the occurrence of a random event.

We have to find the probability of who take the bus and they are juniors

P(take the bus/Juniors)

From the table, let us find the total number of juniors

Among juniors 13 students drive to school, 20 takes the bus and 2 come by walk

Total Juniors = 13+20+2

=35

P(take the bus/Juniors) = 20/35

Divide twenty by thirty five

=0.57

Hence, the probability of P(take the bus/Juniors)  is 0.57 or 57%.

Step-by-step explanation:

Relationship Equation between time and shrimps cleaned : S = 4T; Relationship is inversely proportional; Unit rate of change = 4

Given : 4 Shrimps cleaned every minute.

So, Shrimps cleaned 'S' = 4 times minutes taken 'T' ; S = 4T

The relationship between variables is proportional, as the dependent variable (shrimps) is constant multiples times the independent variable (time), & their ratio remains constant.

It is directly proportional, as both variables (shrimps & time)  move in same direction. One variable increase or decrease, other variable same respectively.

Graph in this case is upward sloping curve from origin, because of  direct proportional relationship respectively.

Unit rate of change denotes constant magnitude of change in a variable with other variable. It is 4 in this case, as time increases the shrimps.

Find the HCF of 72 and 180

well, let's take a look at the table

is g(x) increasing from -2 to -1? hmmm from when x = -2 g(x) = 2, then when x = -1, g(x) = -3, hold the mayo!! it went from 2 to -3, that's just going down, so, nope is not.

is itdecreasing from -1 to 0?  hmmm x = -1, g(x) = -3, as x = 0, g(x) = 2, wait a second!!! it went from -3 to 2, it really went up, so nope, is not decreasing on that interval.

is it increasing from 0 to 1?  let's see, as x = 0, g(x) = 2, as x = 1, g(x) = 17, woahhh!!, it went from 2 and rocketted to 17, yeap, it is increasing as x = 0 to x = 1.

Answer:

852

Step-by-step explanation:

2 times 10 is 20

8 times 109 is 872

You subtract the two values, 872-20=852

If Florida has a population of about 2 X 10'. The Earth has a population of about 8 X 109. Then 852  times more populated is the Earth than Florida.

Two or more expressions with an Equal sign is called as Equation.

Given that

Florida has a population of about 2 X 10'.

The Earth has a population of about 8 X 109.

We need to find  how many times more populated is the Earth than Florida.

We know that

2 times 10 is 20

and  8 times 109 is 872

To calculate how many times more populated is the Earth than Florida. we just required to subtract 872 and 20.

You subtract the two values, 872-20=852

Hence About 852 times more populated is the Earth than Florida.
