Kipish [7]

Answer:

2.65secs

Step-by-step explanation:

Give:

The function h(t)=−16t(t−7) models

the object will hit the ground at h= 0

h(t)=−16t(t−7)

0= -16t(t−7)

0= -16t^2 + 112

16t^2 = 112

t^2 = 7

t= √7

t=2.65secs

Hence, the object object hit the ground at 2.65secs

Varies directly means
if y varies directly as x that means
y=kx where k is a constant


so
y=kx
y=2 and 2/3 when y=1/4 then find k
convert 2 and 2/3 to imporoper fraction for ease
2 and 2/3=6/3+2/3=8/3

8/3=k(1/4)
multiply both sides by 4/1 to clear fraction
32/3=k

so now we have
y=(32/3)x

when x=1 and 1/8
find y
convert 1 and 1/8 to imporopor=9/8

y=(32/3)(9/8)
y=(288)/(24)
y=12

A book sold 31,100 copies in its first month of release. Suppose this represents 6.2% of the number of copies sold to date. How
nydimaria [60]

Answer:

501613 books

Step-by-step explanation:

6.2% of x is 31,100

6.2%=6.2/100=62/1000

(62/1000)*x=31,100

x=31,100/(62/1000) [divide both sides by 62/1000]

x=501612.90=501613 (rounded up)

Hope this helps!
