How many roots does a linear equation have?

Mathematics

Tanya [424]3 years ago

Answer:

A quadratic equation with real coefficients can have either one or two distinct real roots, or two distinct complex roots. In this case the discriminant determines the number and nature of the roots. There are three cases: If the discriminant is positive, then there are two distinct roots.

Step-by-step explanation:

A degree 2 polynomial (a quadratic) has 2 roots. A linear equation in the form y = mx + b is degree 1, since this is and has one root. A linear equation in the form y = c is degree 0, since this is and has zero roots.

Answer:

1

Step-by-step explanation:

A linear equation (degree 1) will have one root. A quadratic equation (degree 2) will have two roots. A cubic equation (degree 3) will have three roots. An nth degree polynomial equation will have n roots.

gregori [183]

The most likely and preferred unit of measurement for the number of strawberries is pounds.

Given that,
Jamison owns a smoothie shop. He is placing an order for strawberries and pineapple juice for a new specialty drink. Which would be the most appropriate unit of measurement for the number of strawberries Jamison will order is to be determined.

<h3>What is a measurement unit?</h3>

Measurement units are the units of measurement of all three states of matter.

Here,
Strawberries have moderate weight and are solid as well so the most preferred unit for the measurement is ounces for moderate use and pound for commercial use,

Since Jamison has a shop, and he uses strawberries for commercial use to make drinks and sell it further, implies pounds is the appropriate unit of measurement.

Thus, The most likely and preferred unit of measurement for the number of strawberries is pounds.

A radioactive gas with a half-life of 2.4 days accidentally leaks into a room. If the radiation level is now 25% above a safe am
Gnom [1K]
Radioactive half-life is the time it takes for half an amount of radioactive material to decay into something else. In this case, it is assumed that the decay product is not radioactive or otherwise hazardous.

We must use the radioactive decay formula to determine at what time the radiation reaches a safe level.
A = Ao[e^(-0.693)(t)(t 1/2) where t 1/2 is the half-life, t is elapsed time, Ao is the original quantity, A is the future quantity.

We are given a half-life of 2.4 days , an Ao of 1.25 and an A of 1.00:

1.00 = (1.25)e^(-0.693)(2.4)t
1.00/1.25 = e^(-1.6632)t
0.8 = e^(-1.6632)t
t = 0.135 days = 3 hrs 15 min

This is the amount of time to a "safe level" using only radioactive decay, not venting or other means.
