I was looking for the answer till this useless website told to create an account so that i could get it. So, i did that and still haven't got the answer. If I was you go to another site and try to find it cause brainly is no help at all. I recommend Answers.com or any other site then this. This site is just plan usless. I mean for real have to have an account to view an answer. Really?! Like come on now. Then you only get to view a few a day before you have to pay like $9.99 to see more. So, go to a site that is actually free. Plz. <span />

What value of k will result in the quadratic having one rational solution if 4x2+kx+4=0?
PtichkaEL [24]

The value of 'k' in the quadratic Equation    4x^{2}+kx+4=0 having one rational solution is k is 8.

<h3>What is a Quadratic Equation?</h3>
  • Quadratic equations are the polynomial equations of degree 2 in one variable of the type f(x) = ax^{2} + bx + c = 0 where a, b, c, ∈ R and a ≠ 0.
  • The standard form of a quadratic equation is ax^{2} + bx + c = 0 .

Here, the given equation is  4x^{2}+kx+4=0

By comparing the given equation with the standard form of the quadratic equation we get,

a = 4

b = k

c = 4

The given quadratic is having one rational solution, which means b^{2} -4ac=0

Therefore,

k^{2} -4 \times 4\times4=0\\k^{2} -64=0\\k^{2} =64\\k=\sqrt{64} \\k=8

Therefore, the value of k is 8.

Answer:

8 is the length of JB

Step-by-step explanation:

<u>Key skills needed: Equations, Congruence</u>

1) We need to find out an equation to make based on the lengths that are given. ΔJMB is congruent to ΔKMB because of Side-Angle-Side:

  • JB is congruent to BK
  • Angle MBK would be a right angle, since it is supplementary to the right angle JBM. Since both are right angles they are congruent.
  • Both triangles have the side BM. Using the reflexive property, BM is congruent to itself, so there you go --> Side-Angle-Side

2) Now since both triangles are congruent, we can make the equation that the length of JM is congruent to the length of MK, using the fact that: If triangles are congruent, then corresponding parts are congruent.

3) This means that 16x -24 = 4x

Subtract 16x from both sides : -24 = -12x

Divide by -12 on both sides and get x = 2

4) Substitute x into the length of JB (16x-24)

16(2)-24 = 32-24 = 8

5) Therefore, the length of JB is 8

The area of a rectangle is 35 cm2 what could the length of the 4th sides be
Talja [164]

Answer:

Step-by-step explanation:

Area of a rectangle is length times width.  Since a rectangle has four sides, there will be two sides that have the length size and two with the width.  Anyway, now we need to find what numbers multiply together to make 35.

7 and 5 are the only whole numbers that multiply together to make 35, so those hve to be the length and width.  So two sides opposite each other are going to be 7 cm and the other two are going to be 5 cm

Can someone solve this???
nalin [4]

Answer:

1. a)x² + y² = 29  ------------------(1)      

y² - x² = 23 ----------------(2)

y²  = 23 + x²

Using the value of y² in the first equation:

<em>x²  + y²  = 29</em>

<em>x²  + (23 + x²)  = 29</em>

<em>2x²  = 6</em>

<em>x² = 3</em>

x = √3

Using the value of x in equation (2)

<em>y²  - x²  = 23 </em>

<em>y²  - 3 = 23</em>

<em>y²  = 26 </em>

<u>y = √26</u>            <u>and</u>            <u>x = √3</u>

<u></u>

<u>b)</u> ( 1 - 12x) / 3 < 0   =   1-12x < 0  =  x > 1 / 12

(1-x) / 2 ≤ (3-x) 3  =  3 - 3x ≤ 6 - 2x  =   -3 ≤ x

In these 2 equations, the value of x will be the values of x common to both the inequalities

Since the second equation starts at a much lower value than the first equation, and they are both going up, all the values for the first equation will also stand for the second equation

Hence, the value of x for the given system of equations is

x  > 1/12

2.

3x² - 7x  + 2 ≥ 0

3x² -6x -1x  + 2 ≥ 0       (splitting the middle term)

3x(x - 2) -(x - 2) ≥ 0

(3x - 1)(x-2) ≥ 0

(3x-1) ≥ 0         or     (x-2) ≥ 0

x ≥ 1/3       or    x ≥ 2

Written above are the 2 solutions for the given equation

4.

We are given that Sin α = (2√3) / 3  or 2/√3

According to the pythagorean law:

<em>sin²α + cos²α = 1</em>

<em>4 / 3  + cos²α = 1</em>

<em>cos²α = (3-4)/3</em>

<em>cos²α = -1/3</em>

cos α = √(-1/3)      or    i / √3    since √-1 is also known as i

<em>Cosec α = 1/ Sin α</em>

<em>Cosec α = 1 / (2/√3)</em>

Cosec α = √3 / 2

<em>Sec α = 1 / cos α</em>

<em>Sec α = 1 /  √(-1/3)</em>

<em>Sec α = (√3)  / (√-1)</em>

Since (√-1) is also known as i , we can write this as:

Sec α = (√3)  / i

<em>Tan α = Sin α / Cos α</em>

<em>Tan α = (2√3 / 3) / (i / √3)</em>

<em>Tan α = (2√3 * √3) / 3 * i)</em>

Tan α = 2 / i

<em>Cot α = 1/Tan α</em>

<em>Cot α = 1 / (2 / i)</em>

Cot α = i / 2
