Find the range. Write your answer in algebraic notation (with the inequalities).

Svet_ta [14]

Answer:

(-3, infinity)

Step-by-step explanation:

Range the y values, meaning up and down. The highest point is neverending therefore, infinity. The lowest point is -3.

I'm pretty sure this is correct.

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

What is the midpoint of a segment with These endpoints (-12,-3) and (3,-8)

Savatey [412]

Answer:

$(\frac{-9}{2},\frac{11}{2})$

Step-by-step explanation:

you have to use the midpoint formula which is

$(\frac{x1+x2}{2},\frac{y1+y2}{2})$

so you plug your numbers in

$(\frac{-12+3}{2},\frac{-3+-8}{2})$

Add the tops

$(\frac{-9}{2} ,\frac{-11}{2} )$

if possible simplify

and that is your answer
