I think 8.0 is the answer
start by plugging in the value you already have, in this case, 5 for y.
-4x-3(5)=17
-4x-15=17
-4x=32
x=-8
however, since a is a+1, a would be 7 (making x 8)
also plz tell me if i read this wrong and it’s actually 1,5 rather than a+1 and 5 cause if i did i’m so sorry lol.
-182=2(1+2x)-2
2*1=2
2*2x=4x
-182=4x+2-2
-182=4x
-45.5=x
Answer:
3.8
Step-by-step explanation:
We are going to plug in the values of the equation, so h(t)=-4.9^2+v0t+h0 will
now be h(t)=-4.9^2+0+70
Now we will find the a b and c of the equation, a=-4.9 b=0 c=70
Now we must find the discriminant of the equation, which the equation for that is D=b^2+(-4)(a)(c)
So D=1,372
Now we use the quadratic formula (see picture below for finished product)
Answer:
The average velocity of the ball is
Step-by-step explanation:
First find the velocities at given times and then form two points. Calculate the slope to find the average velocity. The two points are:
