Answer:
0.034921 miles or 1843774 feet tall
Step-by-step explanation:
Using trigonometric functions we know that and where =angle and r is the hypotenuse of the triangle.
First we will calculate the hypotenuse using the x equation, since we know x = 1 mile (distance from the building on the ground) we have:
Now we will calculate the height of the building using the y equation and so:
The building is 0.034921 miles or approximately 184.3774 feet tall.
Answer:
k = 11
Step-by-step explanation:
Given the points are collinear then the slopes between consecutive points are equal.
Using the slope formula
m =
with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)
m = = =
Repeat with another 2 points and equate to
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)
m = , then
= ( cross- multiply )
k - 1 = 10 ( add 1 to both sides )
k = 11
The absolute value of an given number is always positive. So, when adding two to any positive number will always be greater than the number by itself.
Answer:
Step-by-step explanation:
$15/2.5hr=$6 so if earnings are y and hours worked is x then
y=6x
5=1/5x-3
+3 +3
8=1/5x
8•5 1/5x•5
40=x
