The space shuttle travels at about 28,000 km per hour. Using that information, estimate how many hours it will take the shuttle

Gekata [30.6K]

Answer:

t = 42857.14 h

Step-by-step explanation:

Given that,

The speed of space shuttle, v = 28000 km/h

We know that, the distance between the Saturn and the Earth is 1,200,000,000 km.

Let t be the time.

As we know, speed = distance/time

So,

$t=\dfrac{d}{v}\\\\t=\dfrac{1,200,000,000}{28000}\\\\t=42857.14\ h$

So, the required time is equal to 42857.14 hours.

Fill in the blank.<br> (5x)2<br> a0x2

Yuki888 [10]

Answer: $a_0=25$

Step-by-step explanation:

It is given that, $(5x)^2=a_0x^2$

We need to find the value of $a_0$

As $(5x)^2=a_0x^2$

Solving LHS

$25x^2=a_0x^2$

Now comparing the coefficients of $x^2$

In LHS the coefficient of $x^2$ is 25

In RHS the coefficient of $x^2$ is $a_0$

It implies that, $a_0=25$

So, the value of $a_0$ is 25.

Distance between (0,2) and (0,4)

Lorico [155]

There are many ways to do this, I prefer the distance formula it looks like this:
$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
We are given 2 pairs of coordinates: (0,2) and (0,4)
0=x1
2=y1
0=x2
4=y2
We take the numbers and sub in the values above in place of the variables:
$\sqrt{(0-0)^2+(4-2)^2}$
Simplfy it:
$\sqrt{(0)^2+(2)^2}$
0^2=0
2^2=4
We are left with :
$\sqrt{4}$
$\sqrt{4} =2$
Final answer: 2

What is the length of the indicated side of the triangle?

anastassius [24]

9514 1404 393

Answer:

15 m

Step-by-step explanation:

The area of the square attached to the third side is the sum of the areas of the other squares:

81 m² +144 m² = 225 m²

The side length is the square root of this:
