Attached 3 pictures showing the application of the sum and the product of the roots of quadratic equations in real life

<h3>Further explanation </h3>

A quadratic equation is any equation having the form where x represents an unknown, and a, b, and c represent known numbers with a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term.

Attached 3 pictures showing the application of the sum and the product of the roots of quadratic equations in real life

According to the first picture, it is about the basket ball athlete who shoot a soccer ball. How quadratic are illustrated in the pictures is a professional basketball players such as Stephen Curry can maintain such a consistent shot parabola by knowing the factors in this quadratic equation.

According to the second picture, it is about the bridge having the quadratic equation How quadratic are illustrated in the pictures is there are several basic ideas used in bridge construction. A beam (or truss) bridge consists of a series of piers that are evenly spaced along the entire span of the bridge.  Whereas arch bridges are designed such that the forces acting upon the bridge are evenly distributed along the entire span of the bridge.

According to the third  picture, it is about the soccer ball athlete who shoot a soccer ball. How quadratic are illustrated in the pictures is  when a soccer ball is kicked into the air, we can know how long will the ball take to hit by quadratic equations.

We can apply Quadratic equations in real-world like; sports, bridges, projectile motion, shapes of bananas etc.

Following are three pictures of real world application of quadratics.

Example 1:- Here we can see a Cyclist follows a quadratic path to jump over the obstacles.

Example 2:- Here we see a man throwing a basketball towards the net following a slightly upward direction that goes through a quadratic path.

Example 3:- Here a football player kicks the ball in the sky and it goes through a quadratic path to cover some distance.

How many 1/10's are in 2/5?
goblinko [34]
There is 4 1/10's in 2/5.

You do this by turning 2/5 into a fraction with a denominator of 10, so it will be 4/10. 1/10 + 1/10 + 1/10 + 1/10 = 4/10

Use the equation a = IaIâ
german

Answer:

a) \:\:=\sqrt{14}\cdot \frac{\:\:}{\sqrt{14} }

b)\:\:=\sqrt{29} \cdot \frac{\:\:}{\sqrt{29} }

c) \:\:=7\cdot \frac{\:\:}{7}

Step-by-step explanation:

a) Let <u>a</u>=<2,1,-3>

The magnitude of <u>a</u> is |a|=\sqrt{2^2+1^2+(-3)^2}

|a|=\sqrt{4+1+9}=\sqrt{14}

The unit vector in the direction of a is

\hat{a}=\frac{\:\:}{\sqrt{14} }

Using the relation a=|a|\hat{a}, we have

\:\:=\sqrt{14}\cdot \frac{\:\:}{\sqrt{14} }

b) Let a=2i - 3j + 4k

|a|=\sqrt{2^2+(-3)^2+4^2}

|a|=\sqrt{4+9+16}=\sqrt{29}

\hat{a}=\frac{\:\:}{\sqrt{29} }

Using the relation a=|a|\hat{a}, we have

\:\:=\sqrt{29} \cdot \frac{\:\:}{\sqrt{29} }

c) Let us first find the sum of <1, 2, -3> and <2, 4, 1> to get:

<1+2, 2+4, -3+1>=<3, 6, -2>

Let a=<3, 6, -2>

The magnitude is

|a|=\sqrt{3^2+6^2+(-2)^2}

|a|=\sqrt{9+36+4}=\sqrt{49}=7

The unit vector in the direction of <u>a</u> is

\hat{a}=\frac{\:\:}{7}

Using the relation a=|a|\hat{a}, we have

\:\:=7\cdot \frac{\:\:}{7}
