Answer:

$\huge\boxed{\sf t = 2.34\ seconds}$

Step-by-step explanation:

Given Data:

Speed = v = 855 m/s

Distance = S = 2 km = 2000 m

Required:

Time = t = ?

Formula:

v = S/t

Solution:

Rearrange the formula

t = S/v

t = 2000/855

t = 2.34 seconds

$\rule[225]{225}{2}$

Hope this helped!

Answer:

2.36 seconds

Step-by-step explanation:

it takes 1.18 seconds to go 1 km so for 2 you multiply x 2 and get 2.36.

What is the perimeter of ABC with vertices at A (-11,4) B(-7,8) and C (-4,4)

Alborosie

Answer:

Step-by-step explanation:

Using the distance formula,

$AB=\sqrt{(-11-(-7))^{2}+(4-8)^{2}}=\sqrt{16+16}=4\sqrt{2}\\AC=\sqrt{(-11-(-4))^{2}+(4-4)^{2}}=7\\BC=\sqrt{(-7-(-5))^{2}+(8-4)^{2}}=\sqrt{4+16}=2\sqrt{5}\\\\$

So the perimeter is $4\sqrt{2}+7+2\sqrt{5}$

X² + y² if x = 7 and y = 5. What is the solution to this??

Shtirlitz [24]

Hey there!

x^2 + y^2

= 7^2 + 5^2

= 7 * 7 + 5 * 5

= 49 + 25

= 74

Therefore, your answer should be: 74

Good luck on your assignment & enjoy your day!

Which set of points includes all of the solutions for y = 5/2x + 3/2?

Firdavs [7]

Answer:

Choice A: $(x,\frac{5}{2}x+ \frac{3}{2} )$ . for all real numbers.

Step-by-step explanation:

We are looking for points on the x-y plane which satisfy the equation y = 5/2x + 3/2, and these point are all those that lie on the graph of the equation, which are points $(x,y) = (x,\frac{5}{2}x+ \frac{3}{2} )$ .

Looking at the other choices we see that choice B gives only 3 points, and regardless of whether they lie on the graph of y or not, this choice cannot be correct because 3 points are not all solutions.

The same goes for choice D.

And choice C is just the whole of x-y plane, therefore this cannot be the answer because not every point on the x-y plane is a solution to y = 5/2x + 3/2
