Answer:
See below
Step-by-step explanation:
In math, the distance formula gives us the distance between two
points, (x₁, y₁) and x₂, y₂):

For example, in the triangle below, the distance between the points (1,5) and (-2, 1) is




= 5
You are really using Pythagoras' Theorem to find the distance.
When using the distance formula, you are building a right triangle whose hypotenuse connects two given points.
Area of building is
.
<u>Step-by-step explanation:</u>
Here we have , a figure in given below picture where we have to find volume of this office building , Let's find out:
If we look closely we see that it's basically cuboid with dimensions 50 m by 110 m by 70 m . But there's one small cuboid sliced off from this cuboid with dimensions 50 m by 10 m by (110-90) m i.e. 50 m by 10 m by 20 m .
Area of building = Area of larger cuboid - Area of smaller cuboid
Area of cuboid = 
⇒ Area of building = Area of larger cuboid - Area of smaller cuboid
⇒ 
⇒ 
⇒ 
Therefore, Area of building is
.
Answer:
A is the correct answer
Step-by-step explanation:
To answer this you need to find the value for x that makes the y value zero.
and the value for y when x is zero.
There are 2 intercepts on for a linear equation. One x-intercept (where the graph crosses the x-axis) and one y-intercept (where the graph crosses the y-axis).
Step 1:
The x-intercept is found by setting 'y' equal to zero and solving the equation.
0 = 4x - 2 solve this...
2 = 4x (add 2 to both sides)
0.5 = x (divide both sides by 4 to get x by itself)
So the x-intercept is at the point (0.5. 0)
Step 2: The y-intercept if found by setting 'x' equal to zero and solving
y = (0)x - 2
y = -2
So the y-intercept is at the point (0, -2)
Answer= D
because pi = 3.14
