with what you didnt say what you needed help with
Step-by-step explanation:
Let's try to simplify x^2 + 16. It's a sum of two squares:
x^2 + 16 = 0
x^2 = -16
The problem is, we can't take a square root of a negative. This is where imaginary numbers come in.
Remember that square roots have a plus or minus symbol outside:
±√-16 = ±4i
Our two roots are 4i and -4i. Therefore, the trinomial simplifies to:
(x + 4i)(x - 4i)
If we attempt to divide x + 4 by these two binomials, we will find that 4 and 4i are not like terms. Therefore, we can't simplify this expression.
Ball=sphere
Vsphere=pir^3
d/2=r
d=9
9/2=4.5=r
V=pi4.5^3
V=pi91.125
aprox pi=3.141592
V=286.227
round
V=286 in^3
Bring the 3 to the other side, which makes 11-3 = 8
divide the whole equation by 2, which makes it Root (3x/5) = 8/2
square the whole equation which gives
, 3x/5 = 16
Multiply the equation by 5 which makes it, 3x = 80
finally divide the equation to find x, x= 80/3
Answer:
Step-by-step explanation:
a)
d=0.68t + 1.5 if t time is 3 hrs
d=0.68(3) + 1.5
= 2.04 + 1.5
d= 3.54 ft
b)
d=0.68t + 1.5 if d depth is 4 ft solve for t
d - 1.5 = 0.68t
(d - 1.5) / 0.68 = t
(4 - 1.5) / 0.68 = t
t = 2.5/0.68
t = 3.68 ft
