v = √16 · √d
d = 300 ft
v = √16 · √300
v = √16 · √100 · √3
v = 4 · 10 · √3
<em>v = 40√3 ft/sec </em> <== simplified radical form
That's about 69.3 feet per sec, or 47.2 miles per hour.
(f+g)(x)=f(x)+g(x)=(2x-6)+(4x+7)=6x+1
(f-g)(x)=f(x)-g(x)=(2x-6)-(4x+7)=-2x-13
(fg)(x)=f(x)×g(x)=(2x-6)(4x+7)=8x^2-10x-42
(f+g)(-2)=f(-2)+g(-2)=(2(-2)-6)+(4(-2)+7)=-11
Answer:
16
Step-by-step explanation:
-21x+121
x=5
substitute x
-21(5)+121=-105+121=16
