 , there can be 0 , 1 , or 2 solutions<span> to a quadratic equation, depending on whether the expression inside the square root sign, (b </span>2<span> - 4ac) , is positive, negative, or zero</span>

Here is an easy way to remember, If the discriminant is equal to zero there will be one solution, if the discriminant is less than 0 or negative there are no real solutions, more than 0 or positive there will be two. So one real solution if it is equal

At a clearance sale,Jill got 70% off a silver bracelet.If she paid the cashier $27 ,what was the original price of the bracelet​
mart [117]

Answer:

$38.57

Step-by-step explanation:

Make a proportion.

\frac{27}{x} = \frac{70}{100}

Cross multiply.

27 times 100 = 2700

2700 divided by 70 = 38.57142857

Round the result to the hundredths place.

38.57142857 ≈ 38.57

A 210-N mass is suspended from a horizontal beam by two cables that make angles of 29 degrees and 53 degrees with the beam. Find
natta225 [31]

The tension in the cable is given by the newton's first law will be 163.622 N.

<h3>What is newton's first law?</h3>

The summation of the force is equal to zero.

The formula is given as

ΣF = 0

Where m is the mass of the body and a is the acceleration.

A 210-N mass is suspended from a horizontal beam by two cables that make angles of 29 degrees and 53 degrees with the beam.

Then the tension in the cable will be

Let T be the tension in the cable.

T sin 29° + T sin 53° – 210 = 0

On simplifying, we have

T (sin 29° + sin 53°) = 210

                             T = 163.622 N

More about the newton's first law link is given below.
