What are the zeros of the quadratic function f(x) equals 6X squared +12 X -7

tamaranim1 [39]

The zeroes of the function will be $\rm -1 \pm \dfrac{\sqrt{78}}{6}}$

<h3>What is a Quadratic Function ?</h3>

A quadratic function is given by ax² +bx+c = f(x)

The given quadratic function is

f(x) = 6x² +12x - 7

The zeroes of the function will be given by

f(0) = 0

6x² +12x - 7 = 0

The zeroes are given by

$\rm \dfrac {-b \pm \sqrt{b^2 -4ac}}{2a}$

here

a = 6

b = 12

c = -7

Therefore the zeroes of the function will be

$\rm \dfrac {-12 \pm \sqrt{12^2 -4*6*(-7)}}{2 *6}$

$\rm \dfrac {-12 \pm \sqrt{312}}{12}$

$\rm -1 \pm \dfrac{\sqrt{78}}{6}}$

Therefore these are the two zeroes of the function.

Find the area of this parallelogram

gulaghasi [49]

Answer:

140 cm²

Step-by-step explanation:

The height of the parallelogram is 10cm . And its base is 14cm .We know that the area of parallelogram is product of base and height .

⇒ Area = base × Height

⇒ Area = 14cm × 10cm

⇒ Area = 140 cm² .

<h3>Hence the area of the parallelogram is 140 cm² .</h3>

A clothing manufacturer produces one type of sweater that earns $4 profit for each one sold. The business manager requires that

eimsori [14]

The least number of sweaters that must be produced each hour to earn a profit of at least $100 is 37.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

A clothing manufacturer produces one type of sweater that earns $4 profit for each one sold.

Let x be the number of sweaters that must be produced each hour to earn a profit of at least $100

Total selling price if earns $4 profit for each one sold = 4x

The expenses for running the machine are $45 per hour.

4x - 45 ≤ 100

4x ≤ 145

x ≤ 145/4

x ≤ 36.25

Number of sweater(estimate value) = 37

Thus, the least number of sweaters that must be produced each hour to earn a profit of at least $100 is 37.
