For the equation y= 6x2 - 9x + 22, choose the correct application of the quadratic formula.

Answers

Answer 1

Answer:

The correct application of the quadratic formula is:

$x=(9\pm √((-9)^2-4(6)(22)))/(2(6))$

Step-by-step explanation:

The quadratic equation is given by:

$y=6x^2-9x+22$

We know that the solution of the quadratic equation:

$y=ax^2+bx+c$

is given by:

$y=(-b\pm √(b^2-4ac))/(2a)$

Here we have:

$a=6$

$b=-9$

and

$c=22$

Hence, the quadratic formula is given by:

$x=(-(-9)\pm √((-9)^2-4\cdot (6)\cdot (22)))/(2\cdot (6))$

i.e.

$x=(9\pm √((-9)^2-4(6)(22)))/(2(6))$

Answer 2

Answer:

it’s the last option

the measure of one angle of a right triangle is 38 degrees more than the measure of the smallest angle. find the measures of all three angles.

Answers

Answer:

26° , 64° , 90° all three angles of right angle triangle.

Step-by-step explanation:

Given : the measure of one angle of a right triangle is 38 degrees more than the measure of the smallest angle.

To find : find the measures of all three angles.

Solution : We have given a right angle triangle

We know that in right angle one angle = 90 ° .

Let the smaller angle = x .

According to question :

Other angle = 38 + x

By the angle sum property of triangle: sum of all angle is 180° .

x + 38 +x + 90 = 180.

2x + 38 + 90 = 180.

2x + 128 = 180 .

On subtracting both sides by 128.

2x = 180 - 128.

2x = 52

On dividing both sides by 2.

x = 26.

Smaller angle = 26

second angle 26 +38 = 64

Third angle = 90.

90+ 64 + 26 = 180.

Therefore, 26° , 64° , 90° all three angles of right angle triangle.
