Answer:
The distance from the base of the building to the base of the ladder is 13.56 feet.
Step-by-step explanation:
This can be solved using Pythagorus theorem.
If the length of the ladder is taken as the hypotenuse and the distance from the building as the base of the triangle then the altitude can be found out by using
c²= a²+b²
Where c is the hypotenuse and b is the base and a is the altitude
Putting the values
25²= a²+ 21²
a²= 25²-21²
a²= 625-441
a²= 184
a= √184= 13.56 feet
The distance from the base of the building to the base of the ladder is 13.56 feet
Answer:
A(1,6)
Step-by-step explanation:
SOOO, we're gonna graph it okay?
I graphed it, and A was the only one on the line.
I hope this helps
In solving the volume of a square pyramid the following formula is to be used:
V = a² h/3
where;
a = base edge
h = height
Thus, the V ≈ 2.53 × 10⁵. Computed in another way:
V = (54)² × (260/3)
= 2916 × 86.67
= 252,729.72
≈ 2.53 × 10⁵
To solve this, we have to complete the square of
To do this with halve the and get rid of the x, then get rid of the power on , and then put them all in brackets, and the square the bracket, like so:
becomes
However does not equal
If we expand we get instead.
So to make it equal, all we do is subtract 1.
So when we complete the square of , we get
---------------------------------------------------------
So becomes:
x + 1 = ±√6
x = -1 ± √6
