The distance from the lighthouse to the boat will be given by:
tan θ=opposite/adjacent
θ=angle of depression=23
opposite= height of the lighthouse
adjacent=distance from the boat to the bottom of the light house
hence
tan 23=210/a
thus solving for a we obtain:
a=210/tan23
hence
a=494.73 ft
Slope= 1/2
Y intercept= (0,2)
Explanation:
Slope-intercept form is y=mx+b
-2x+4y=8
-8-2x=-4y
Divide by -4
2+1/2x=y
Y=1/2x+2
Answer:
B) y=-3/2x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-6-3)/(2-(-4))
m=-9/(2+4)
m=-9/6
simplify
m=-3/2
y-y1=m(x-x1)
y-3=-3/2(x-(-4))
y-3=-3/2(x+4)
y=-3/2x-12/2+3
y=-3/2x-6+3
y=-3/2x-3
Answer:
B
Step-by-step explanation:
multiply 18% and 220 which is 39.6
subtract 39.6 from 220 which is 180.4
simplify
9514 1404 393
Answer:
- waffle $8
- hashbrowns $1.50
Step-by-step explanation:
Using w and h for the costs of a waffle and hashbrowns, respectively, we can write the equations for the purchase amounts as ...
w + h = 9.50
2w + 3h = 20.50
Subtracting twice the first equation from the second gives ...
(2w +3h) -2(w +h) = (20.50) -2(9.50)
h = 1.50 . . . . . . simplify
w = 9.50 -h = 8.00 . . . . . find w using the first equation
The cost of a waffle is $8.00; the cost of hashbrowns is $1.50.
