Answer:

The value of \int _C\bigtriangledown f\cdot dr is 40.

Step-by-step explanation:

It is given that the gradient of function is continuous.

By fundamental theorem for line integrals,

\int _C\bigtriangledown f\cdot dr=f(Q)-f(P)

Where, C starts from P and end at the point Q.

We have to find the value of \int _C\bigtriangledown f\cdot dr.

The function is defined from contour line 10 to contour line 50.

\int _C\bigtriangledown f\cdot dr=50-10

\int _C\bigtriangledown f\cdot dr=40

Therefore the value of \int _C\bigtriangledown f\cdot dr is 40.

A projectile is fired directly upward. The compound inequality 89 – 9.8t < 10.6 or 89 – 9.8t > 20.4 represents a projectil
Tom [10]

Given compound inequality 89 – 9.8t < 10.6 or 89 – 9.8t > 20.4.

Let us solve them one by one.

89 – 9.8t < 10.6

Subtracting 89 from both sides, we get

89-89 – 9.8t < 10.6 - 89

-9.8t < -78.4

Dividing both sides by -9.8, we get

t > 8.

<em>Note: Inequality sign get flip on dividing both side by a negative number.</em>

89 – 9.8t > 20.4

Subtracting 89 from both sides, we get

89-89 – 9.8t < 20.4 - 89

-9.8 t < - 68.6.

Dividing both sides by -9.8, we get

t < 7

<em>Note: Inequality sign get flip on dividing both side by a negative number.</em>

<h3><em> The solution to the inequality 89 – 9.8t < 10.6 is </em>t > 8. </h3><h3> The solution to the inequality 89 – 9.8t > 20.4 is t < 7.</h3>

When the projectile hits the ground:

89 – 9.8t = 0

Subtracting 89 from both sides, we get

89 - 89 – 9.8t = 0 -89.

-9.8t = -89.

Dividing both sides by 9.8, we get

<h3>to the nearest whole second  t is about 9 seconds.</h3><h3>Therefore, variable solution set is {t < 7, t > 8, t = 9}.</h3><h3 />
