Answer:
-123
Step-by-step explanation:
The remainder theorem says that when a polynomial is divided by a linear factor x - c (note the minus sign), the remainder is the value of the polynomial at x = c.
When a polynomial P(x) is divided by x - c, the remainder is P(c). In other words, to find the remainder, plug in c for x.
You're dividing by x + 4 which is the same thing as x - (-4) -- the role of c is being played by -4.
3(–4)^3 – (–4)^2 – 20(–4) + 5 = –123
3O=12/3 Divide both sides by 3.
/3
O=4

Answer:
The answer is 13/4
Step-by-step explanation:
I divides and cross miltiplied.
Check the picture below.
now, keeping in mind that gravity will pull the projectile down, and that'd be 9.8 m/s², that gets halfed for the initial velocity equation, so 9.8/2 or 4.9 m/s².
how high will it go? well, notice in the picture, it'll go as high as its vertex,
when will it return to the ground? well, notice the picture, when y = 0.
so after "t" seconds it comes back down.
notice is 0 at two points, at t=0 or 0 seconds, because it just took off the ground, and again the second time, when it comes back down.
