mark me brainlist plz.
Answer:
x-intercept = 4
y-intercept = -1
As ordered pairs they would be ( 4, 0) and ( 0, -1)
Step-by-step explanation:
The line goes through 4 on the x line and goes through -1 on the y line.
As an ordered pair you just put the numbers in their x and y spots being ( x, y )
With 4 being on the X and -1 being on the Y it would make them ( 4, 0) and
( 0, -1).
Answer:
amount in 30 years is $1787.0977
interest is $1387.0977
Step-by-step explanation:
Given data
principal amount = $400
rate = 5 % = 0.05
time period = 30 years
to find out
amount in 30 years and total interest
Solution
we know its interest compounded monthly so n = 12
and interest compounded monthly formula is
amount = principal 
............1
put the value principal , n , rate and time in equation 1
we get amount
amount = 400 
amount = 1787.0977
amount in 30 years is $1787.0977
and interest = amount - principal ............2
put the value amount and principal in equation 2
we get interest = $1787.0977 - $400
interest =$1387.0977
Answer:
Unknown weight is 11.5kg.
Step-by-step explanation:
Square weight is 4kg. 4×5 =20.
Round weight is 2.5kg. 2×4+2×2.5=13.
Left pan is 4+3×2.5=4+7.5=11.5.
Answer:
= - √3/3
Step-by-step explanation:
Tan ( 11π/6)
= Tan ( (12π - 11π)/6)
= Tan ( 2π - π/6)
using Tan ( A - B) = (Tan A - TanB)/(1 + TanATanB)
A = 2π B = π/6
= (Tan 2π - Tan π/6)/( 1 + Tan2π * Tan(π/6)
Tan 2π = 0
=> ( 0 - Tan π/6)/(1 + 0)
= - Tan π/6
Tan π/6 = √3/3
= - √3/3
