Solve your equation step-by-step.

(2x−1)(x+7)=0

Simplify both sides of the equation.

2x2+13x−7=0

Factor left side of equation.

(2x−1)(x+7)=0

Set factors equal to 0.

2x−1=0 or x+7=0

x=1/2 or x=−7

Find the sum of the geometric sequence –3, 15, –75, 375, … when there are 8 terms
arlik [135]
First, we need to solve for the common ratio from the data given by using the equation.

a(n) = a(1) r^(n-1)
15 = -3 r^(2-1)
-5 = r
r = -5

Then, we can find the sum by the expression:

S(n) = a(1) ( 1 - r^n) / 1-r
S(8) = -3 (1 + 5^8) / 1+5
S(8) = -195313

Can someone please answer this and explain it?
professor190 [17]

Answer:

Velocity = displacement / time

Distance = 3t^2 +2t +6 to find distance you need to plug in time = 2 sec

Distance = 3(2)^2 +2(2) +6

Distance = 3(4) +4 + 6

Distance = 12 + 4 +6

Distance = 22 meters

In this problem the displacement is the distance.

so

Velocity = 22 meters / 2 second

Velocity = 11 meters/second

Does this help?
