Answer:
Cube 1
Step-by-step explanation:
Volume of cube 1
V = 25*25*25 = 15625
Volume of 2 cubes
V = 24*24*24 = 13824
V =7*7*7 =343
V total = 14167
The total volume is greater for the 1 cube
30/20= 1 and 10/20 in simplest form that is 1 and 1/2
Use the distance of 1 lap to multiply the number of laps ran
Answer:
7.81
Step-by-step explanation:
its a triangular shape
let x = 4 + 2 = 6
let y = 5
length between two points = h
h² = x² + y²
h² = 6² + 5²
h = sqrt of 61
h = 7.81
Answer:
The value of given trigonometrical expression is cos²x + sin²x = 1
Step-by-step explanation:
Given trigonometrical expression as :
(
) - sec x = tan x
Or, (
) = tan x + sec x
or, (
) = (
) + (
)
or, (
) = (
)
Now, cross multiplying both side
I.e (cos x) × (cos x) = ( 1 - sin x ) × ( 1 + sin x )
or, cos²x = 1 - sin² x
or, cos²x + sin²x = 1
So, Value of expression is cos²x + sin²x = 1
Hence The value of given trigonometrical expression is cos²x + sin²x = 1 answer
