Answer: Sin N = 
Step-by-step explanation:
Since we have given that
In triangle MPN, ∠P=90°
As we know the formula for "Trigonometric Ratios":
By Pythagorus theorem , we get
So, we get,
Hence, Sin N =
Sub g to (-3) and then solve from there using PMDAS and equation solving skills, Photomath is a fantastic resource
Answer:
Volume = ⅓n²(n-1) or ⅓(n³ - n²)
Step-by-step explanation:
Given
Solid Shape: Right pyramid
Edge= n units
Height= n - 1 units
Required
Volume of the pyramid
The volume of a right pyramid is
Volume = ⅓Ah
Where A represents the area of the base
h represent the height of the pyramid
Since it has a square base;
The area is calculated as follows
Area, A = edge * edge
A = n * n
A = n²
Recall that
Volume = ⅓Ah
Substitute n² for A and n - 1 for h
The expression becomes
Volume = ⅓ * n² * (n - 1)
Volume = ⅓n²(n-1)
The expression can be solved further by opening the bracket
Volume = ⅓(n³ - n²)
Answer:
(-1, -1.5)
Step-by-step explanation:
A coordinate is a point (a single place) on a graph. Coordinates can be recorded as (#, #).
The first number is the one on the x-axis (left/right) and the second number is the one on the y-axis (up/down). (x, y) The middle point, where the x-axis and y-axis meet is called the origin, and is at (0,0).
The point that marks the campground is at -1 on the x-axis and -1.5 on the y axis.
Because the y-axis has two lines for every whole number, the line in between is the halfway mark and counts as a 0.5 increment.
