Answer:
I want to say letter c. p=3
The answer is C.
y= -4x + 8
You can plug in your coordinates.
For (0,8), plug in the x and y values.
8 = -4(0) +8
8 = 0+8
8=8 so, this works
For (2,0) plug in your coordinates.
y = -4x + 8
0 = -4(2) + 8
0 = -8 + 8
0=0
If both coordinates work for the equation, then they pass through that line.
Step-by-step explanation:
LHS= 1 + cot^2A/1+cosecA
=(1+cosecA + cot^2A)/1+cosecA
{By using basic trigonometric theorem cot^2A = cosec^2A - 1}
=(1+cosecA + cosec^2A - 1)/(1+cosecA)
=(cosecA + cosec^2A)/(1+cosecA)
=[cosecA (1+cosecA)]/(1+cosecA)
{Cancelling 1+cosecA}
=cosecA
Answer:
is there any choices?
Step-by-step explanation:
Answer:
Correct answer: V = 82.5 in³
Step-by-step explanation:
This is a regular five sided prism.
Given:
The base edge a = 4 in
The radius of the inscribed circle or the height of an isosceles triangle
Ri = h = 2.75 in
Prism height H = 3 in
The base consists of five isosceles triangles
The area of one triangle is:
A₁ = a · h / 2
The area of the base is:
B = 5 · A₁ = 5 · a · h / 2
B = 5 · 4 · 2.75 / 2 = 27.5 in²
The volume of the prism is:
V = B · H = 27.5 · 3 = 82.5 in³
V = 82.5 in³
