Step 1 : 11875=2x+2391 Step 2: 11875-2391=2x Step 3: 9484=2x Step 4: 9484/2=x Step 5: x=4742

The solution to a quadric equation are x=2 and x=7. If k is a nonzero constant which of the following must be equal to the quadr

nikklg [1K]

Answer:

The quadratic equation form is x² - 9 x + 14 = 0

Step-by-step explanation:

Given in the question as ,

The solution of quadratic equation are x = 2 and x = 7

The constant K is a non-zero number

Now , let the quadratic equation be , ax² + bx + c = 0

And sum of roots = $\frac{ - b}{a}$

product of roots = $\frac{c}{a}$

So, 2 + 7 = $\frac{ - b}{a}$

Or, 2 × 7 = $\frac{c}{a}$

I.e $\frac{ - b}{a}$ = 9 , $\frac{c}{a}$ = 14

Or, b = - 9 a And c = 14 a

Put this value of b and c in standard form of quadratic equation

I.e ax² + bx + c = 0

Or, ax² - 9 ax + 14 a = 0

Or , a ( x² - 9 x + 14 ) = 0

∴ a = 0 And x² - 9 x + 14 = 0

Hence , The quadratic equation form is x² - 9 x + 14 = 0 Answer

In parallelogram ABCD, the measure of angle ABC is 130, find the measure, in degrees of angle DAB

77julia77 [94]

Angle ABC = 130
Angle ABC = Angle ADC = 130 (Opposite angles are equal)
Angle DAB = 180 - 130 = 50 (consecutive interior angles)

I HOPE IT IS HELPFUL:D

Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.

Margaret [11]

Answer:

The correct option is 3.

Step-by-step explanation:

Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.

J = 90°, J' = 90°

K = 65°, K' = 65°

L = 25°, L' = 25°

In a rigid transformation the image and pre-image are congruent. Reflection, translation and rotation are rigid transformation.

In a non rigid transformation the image and pre-image are similar. Dilation is a non rigid transformation.

In a rigid or a nonrigid transformation, the corresponding angles are same. If the corresponding sides are same, then it is a rigid transformation and if the corresponding sides are proportional, then it is a non rigid transformation.

It can be a rigid or a nonrigid transformation depending on whether the corresponding side lengths have the same measures.

Therefore option 3 is correct.

Assume that a demand equation is giben by q = 7000-100p. Find the marginal revenue for the given production levels (levels of q)

nata0808 [166]

Answer:

Option B.

Step-by-step explanation:

The demand function is

$q=7000-100p$

where p is price.

Solve the demand equation for p.

$100p=7000-q$

$p=\dfrac{7000-q}{100}$

The revenue function is

$R(q)=qp$

Substitute the value of p in the above function.

$R(q)=q(\dfrac{7000-q}{100})$

$R(q)=\dfrac{7000q-q^2}{100}$

Differentiate with respect to q.

$R'(q)=\dfrac{7000-2q}{100}$

Equate R'(q)=0,

$\dfrac{7000-2q}{100}=0$

$7000=2q$

Divide both sides by 2.

$3500=q$

Therefore, the correct option is B.
