Answer:
-8
Step-by-step explanation:
y-intercept of f(x)=3x^2 -2x-8 when : x =0
f(0) = 3(0)² -2(0) -8 = - 8
Answer:
x=8
Step-by-step explanation:
Cross multiply to solve
2/x=4/16
4*x=2*16
4x=32
Divide by 4 on both sides
x=8
So,
2/8=4/16
Hope this helps! :)
so.. to get every angle, simply plug in 10 for "x" for each.
Answer:
1. 30ft
2. 0.4 min
Step-by-step explanation:
In this question, apply sine law which states that sine Ф= opposite/hypotenuse
The general formulae; is SOHCAHTOA where ;
(SOH) sineФ=opposite/hypotenuse ; (COH) cosine Ф= adjacent/hypotenuse and (TOA) tan Ф=opposite/adjacent
In the question the height of the two floors is the " c" and the angel at the base is 60° and distance the conveyor travels is the hypotenuse
Hence;
If 75ft=1min
30ft=?........................simple math
30/75 = 0.4 minutes
