Question 231745: Please someone help me with these. I am not sure I am doing them right.
Solve:
1. y square = 49
The square root of 49 is _7 and + 7
y = -7 and + 7
2. (z + 3) squared = 36
z squared + 9 = 36
z squared= 36-9=27= (3x3x3)
=============================
~~~~~~~I can't go on....please help me
3. x squared + 18x - 17 = 0
x^2+18x-17=0
delta= (18)^2-4(1)(17)=256
square root of delta will be:16
therefore we will have two solutions
x= (-19-16)/2 = -35/2
y= (-19+16)/2= -3/2
Thank you very much. Carrie

Question 232290: Story problem:
A tennis ball is hit upward with a velocity of 48 feet per second. Ignoring the height of the tennis player, how long does it take for the ball to fall to the ground?
Formula:
h(t)= v0t-16t^2
h(t) is height of an object (feet)
v0 is object's initial velocity (feet per second)
t is time (seconds)
so far i have 3 seconds but that is just one of the roots of the quadratic, not time.

Question 232780: f(x)= 7x^2+28x+28
i think i solved it this far.
f(x)=7(x^2+4x)+28
f(x)=7(x^2+4x+4-4)+ 7(-4)+28
f(x)=7(x^2+4x+4)+0
f(x)=7(x^2+4x)=
f(x)=7(x+2)^2
vertix is (-2,0)
so if i graph it x= -2 and y = 0
i have to use more points i tried
x= -1 y=7
x= -3 y= 7
x= -1.5 y= 1.75
i need to know if im rite and what other point i can use
