Answer:
10
Step-by-step explanation:
F(x) = 3x+1, for f. 3)
3x3=9
9+1=10
32 7/8 would be the answer. All you have to do is find a number multiplied by & that gets you close enough to 39
Answer:
1/2 + 5/2 i
Step-by-step explanation:
(-5+i) i
---------* --------
2i i
cannot have i in the denominator so we multiply by i
(-5+i) i -5i + i^2
---------* -------- = ----------------
2i i +2i^2
remember i^2 = -1
-5i + -1 -1 -5i
= ---------------- = ------------------
+2(-1) -2
get rid of the negative in the denominator by multiplying the top and bottom by -1
(-1 -5i) * -1
= ------------------
-2*(-1)
(1 +5i)
= ------------------ = 1/2 + 5/2 i
2

factorising the first denominator
x²-2x-3 = x² -3x+x-3 = (x+1)(x-3)
(a) 
finding LCD
(b) LCD of (x-3)(x+1) and (x-3) is (x-3)(x+1)
(c)

(d)



Answer:
82.4 ft^3
Step-by-step explanation:
Diameter=5.4ft
Radius=diameter/2
=5.4ft/2
=2.7ft
π=3.14
Volume of a sphere=4/3πr^3
=4/3×3.14×2.7^3
=4/3×3.14×19.683
=4/3×61.80462
=247.21848/3
=82.40616
Approximately
82.4 ft^3
