Answer:
Step-by-step explanation:
Simply plug each x value into the equation
1.
-3, 0, 3, 6, 8, yes it is linear, it doesn't have any exponents
2.
Same thing
5,2,1,2,5, it has exponenets and is not linear
Set the quadratic = to 0 and solve for time, t:
-16t^2 - 8t + 20 = 0
Reduce this to:
-4t^2 - 2t + 5 = 0
Here a= -4, b= -2 and c =5. Then,
2 plus or minus sqrt( 4-4(-4)(5) )
t = ---------------------------------------------
-8
2 plus or minus sqrt(84)
= ------------------------------------
-8
Finish evaluating this. If either outcome is negative, discard it.
The result will be the number of seconds required for the ball to hit the grnd.
Answer:
The rectangle ABCD and the congruent angles are shown in the diagram below.
We know that T is a midpoint.
That gives us the length of TD = length of TB, also TA = TC
Look for triangle ATD and BTC, we have so far that:
TD = TB and TA = TC
∠DAT = ∠BCT (properties of alternate angles)
∠ATD = ∠BTC (properties of opposite angles)
By the postulate SAS (Side Angle Side) we can deduce that AD = BC
Answer: TB = TD (Fourth option)

Answer:
I think it is 201.75 but I'm not sure
Answer:
A = B
Step-by-step explanation:
A = 8! = 8*7*6*5*4*3*2*1 = 40320
B = 8P8 = 8! / ( 8-8)! = 8! = 0! = 8! /1 = 8! = 40320
A = B
