7 0

Answer:

we know that, 1miles/hour = 0.45m/s

or, 1meters/second = 1/0.45

1m/s = 2.22222222222

Step-by-step explanation:

Then,

72.0 meters/second = 72.0*2.22222222222

=160 miles per hour.

Shannon is 16.299 miles from the border. Greta is 16.92 miles from the border. If they move towards a given point on the border

Bond [772]

Shannon will get there first. This is because 16.299 is less than 16.92. When looking at decimals, the first number at the decimal is most important.

A roller coaster starts with the cars being pulled up a ramp. The mass of the cars is estimated by the function m(p) = 175p + 1,

KiRa [710]

Answer:

$E(p)=51,450p+346,920$

Step-by-step explanation:

The function

$m(p) = 175p + 1,180$

gives the mass of the car as a function of the number of passengers in it.

And the function

$E(m) = 9.8m*h$

gives the potential energy of the car as a function of the car's mass.

Now if the height of the ramp is 30 meters, we have

$E(m) =9.8m*(30)$

$E(m) =294m$

And to find the potential energy as a function of the number of passengers, we just substitute $m(p)$ into $E(m)$ to get:

$E(m(p))=294(175p+1180)$

$\boxed{ E(p)=51,450p+346,920}$

which gives the potential energy as a function of the number of passengers.

14. Compare the graph below to the function

Dahasolnce [82]

Answer:

Option (2)

Step-by-step explanation:

Parent function has been given as,

f(x) = $\sqrt{x}$

When translated by 3 units left,

f(x + 3) = $\sqrt{(x+3)}$

g(x) = $\sqrt{(x+3)}$

If the translated function is stretched vertically by a scale factor = k

New function will be,

g'(x) = $k\sqrt{(x+3)}$

Since a point (1, 4) passes lies on the transformed function.

g'(1) = $k\sqrt{(1+3)}$

4 = 2k

k = 2

Therefore, transformed function represents the translation by 3 units in the negative side of the x-axis and stretched vertically by 2 units.

Option (2) will be the answer.
