Answer: 38
Step-by-step explanation: to evaluate an expression for these variables, plug in those numbers for the variables.
Plugging in -1 for y and -19 for z gets you this:
-2(-1)^2(-19)
Now simplify according to order of operations (PEMDAS - parenthesis exponents multiplication/division addition/subtraction)
-1^2 = 1
-2(1) = -2
-2(-19) = 38
Your answer is 38
Hi. Good?
To solve is to use the formula:
D = v.t
14 = v. 15
v= 14/15
v = 0,9333..mpm
15m = 900s
14 = v. 900
v=14/900
v=0,01555...mps
I put the result in miles per minute and miles per second.
Thanks, I hope I have helped.

Answer:
27.4 metres
Step-by-step explanation:
Um, your question is missing the x's. I'm going to assume, -4.9x^2+22x+5.5
= -4.9(3)^2+22(3)+5.5
= 27.4
At 3 seconds the ball is 27.4 metres above the ground.
