Answer:

Step-by-step explanation:

Units of Lenght :

Km
Hm
Dam
m
dm
cm
mm

÷10 for each step ↑
x10 for each step ↓

7200 km = 7200.1000 m

1 h = 60 minutes

every minute has 60 s.

1 h = 60 x 60 s

$\frac{7200}{1}$ km/h = $\frac{7200.1000}{60.60}$ m/s

$\frac{7200.1000}{60.60} = \frac{2.1000}{1}$

2.1000 = 2000

Hope this helps ^-^

Answer:

A $=$ 2000 m/s

Step-by-step explanation:

When you multiply a km/h with $\frac{5}{18}$ , it converts to m/s.

So,

$7200$ × $\frac{5}{18}$ $= 2000$ m/s

If integral 1 to 5 f(x)dx =36/15 what is the value of integral from 5 to 1 f(x)dx?

fredd [130]

Answer:

-36/15

Step-by-step explanation:

If the indefinite integral of f(x)dx is F(x), then your integral from 1 to 5 is ...

F(5) -F(1) = 36/15

The integral in the reverse direction is ...

F(1) -F(5) = -(F(5) -F(1)) = -36/15

A ball is tossed up in the air at an initial rate of 50 ft/sec from 5 ft off the ground.

Fofino [41]

Answer with Step-by-step explanation:

Since we have given that

Initial velocity = 50 ft/sec = $v_0$

Initial height of ball = 5 feet = $h_0$

a. What type of function models the height (ℎ, in feet) of the ball after tt seconds?

As we know the function for height h with respect to time 't'.

$h(t)=-16t^2+v_0t+h_0\\\\h(t)=-16t^2+50t+5$

b. Explain what is happening to the height of the ball as it travels over a period of time (in tt seconds).

What function models the height, ℎ (in feet), of the ball over a period of time (in tt seconds)?

if it travels over a period of time then time becomes continuous interval . so it will use integration over a period of time

Our function becomes,

$h(t)=\int\limits^t_0 {-16t^2+50t+5} \, dt$

Max and his friend zeke are comparing their ages. they figure out that if they double maxs age from 3 years ago and add it to ze

chubhunter [2.5K]

The first step of solving this problem is to find your x, which is the unknown number. The unknown number is the age of Max. Once you find the x you can write out your equation.

The equation for this problem is:

2x+8=26

the first step is to subtract 8 from both sides so that all you have on the left side is 2x and your equation will look like ths:

2x=18

after subtracting the 8; divide everything by the coefficient of x which is 2, your result is:

x=9

Max is 9 years old.
