Answer:

The expression 3(2a+5) is equivalent to 6a + 15 .

Option (b) is correct .

Step-by-step explanation:

As given the expression in the question be as follows

= 3 (2a + 5)

First open the bracket of the above expression

= 3 × 2a + 3 × 5

Sloving the above

= 6a + 15

Therefore  the expression 3(2a+5) is equivalent to 6a + 15 .

Option (b) is correct .

3(2a+5)
6a+15 divide both sides by 6
a=2.5

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
