Answer:

Yes

Step-by-step explanation:

Yes it is possible to solve a quadratic equation that is not factorable over the set of integers.

The solution may vary like Integers, rationals, irrationals or complex solutions.

To find two roots of the equation we can always use the formula given below to solve a quadratic equation,

For the quadratic equation,

$ax^2+bx+c=0$ , we have,

$x= \frac{-b\pm \sqrt{b^2-4 ac}}{2a}$

If the discriminant is greater than $b^2$ , we get complex roots.

Answer:

$455.84

Step-by-step explanation:

find area of the two halves of the circle and the rectangle

area of circle= $\pi r^{2}$

where r= 2 ft

therefore

$\pi (2)^{2}\\=12.56 ft^{2}$

area of rectangle= $w*l$

where w= 4ft and l= 5ft

therefore

$(4)(5) \\=20 ft^{2}$

add areas together

$12.566 + 20 \\=32.56 ft^{2}$

it costs $14 per square foot and there are 32.566 square feet, so multiply

$14 * 32.56 \\= $455.84$

Step-by-step explanation:

since they gave the point (0,0) and slope 3

y=mx+b

Which of the following have a frequency factor of b = 1?

icang [17]

Period =2r /b
assume frequency factor meaning angular frequency "b"
then
2r= 2r/b => b=1

Marcie cooked dinner for herself. The original recipe has a serving size of 3 and requires three and three sevenths pounds of ch

Sati [7]

Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

$3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}$

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

$\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}$

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

one and three seventh pounds.
