A parachutist's rate during a free fall reaches 165 feet per second. What is this rate in meters per second? At this rate, how m

Fiesta28 [93]

Assuming that:

1
m
=
3.3
f
t
1m=3.3ft

We can make the conversion from feet per second to meters per second with this procedure:

(
165

f
t
s
)
(
1

m
3.3

f
t
)
=
50

m
s
(165
s
ft

)(
3.3 ft
1 m

)=50
s
m

Let
x
x be the amount of meters the parachutist will fall during 15 seconds of free fall

Having that in 1 second the parachutist falls 50 meters, we can calculate
x
x :

x
=
(
50

m
s
)
(
15

s
)

x=(50
s
m

)(15 s)

x=750 m

What is the rate of change for f(x) =7 sin x-1 on the interval from x=0 to x=piover 2

Oksi-84 [34.3K]

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\
of\ change
\end{array}\\\\
-------------------------------$

$\bf f(x)= 7sin(x)-1 \qquad 
\begin{cases}
x_1=0\\
x_2=\frac{\pi }{2}
\end{cases}\implies \cfrac{f\left( \frac{\pi }{2} \right)-f(0)}{\frac{\pi }{2}-0}
\\\\\\
\cfrac{[7\cdot 1-1]~-~[7\cdot 0-1]}{\frac{\pi }{2}}\implies \cfrac{6-(-1)}{\frac{\pi }{2}}\implies \cfrac{6+1}{\frac{\pi }{2}}\implies \cfrac{7}{\frac{\pi }{2}}\implies \cfrac{14}{\pi }$

M - 4 = 2m How do i solve this ?

Varvara68 [4.7K]

You need to move over the m to 2m and then subtract 2m-m. Now what will be the answer? try to do it and then send it to me
