The daily cost of hiring a plumber, y, to work hours on a repair project can be modeled

Mathematics
1 answer:
Alex73 [517]3 years ago
4 0

Answer:

  [50, 410]

Step-by-step explanation:

If the plumber works 0 hours, he still charges $50, so that is the minimum of the range of charges.

If the plumber works 8 hours, his hourly charge of 8×$45 = $360 is added to his fixed charge of $50 for a total of $410. That is the maximum of the range of daily charges.

The range of the function is $50 to $410.

The equation r(t)= (2t)i + (2t-16t^2)j is the position of a particle in space at time t. Find the angle between the velocity and
ankoles [38]

Answer:

The answer is 135 degrees.

Step-by-step explanation:

As we are given the position. If we take the <u>derivative</u>, we get the velocity vector. If we take the <u>derivative</u> again, we find the acceleration vector of the particle.

r(t)=(2t)i+(2t-16t^{2})j

V(t)=2i+(2-32t)j

a(t)=-32j

At time t=0;

v(t)=2i+2j

a(t)=-32j

As i attach in the picture the angle between the velocity and acceleration vector is (45+90)=135 degrees

Find the missing length
SashulF [63]

Answer:

c = 37

Step-by-step explanation:

Pythagorean thm formula:

a² + b² = c²

Given:

a = 12

b = 35

Work:

a² + b² = c²

12² + 35² = c²

144 + 1225 = c²

c² = 1369

\sqrt{c^2} =\sqrt{1369}

c = 37
