4*(1/2)^0 + 4*(1/2)^1 + 4*(1/2)^2 =
4 + 2 + 1 = 7
So basycilly slope intercept form is y=mx+b where m=slope and b=y intercept
slope=-1
subsiute
y=-1x+b
y=-x+b
so we are given the point (-3,2)
x=-3 and y=2 is one solution
subsitue and solve for b
2=-(-3)+b
2=3+b
subtract 3 from both sides
-1=b
the slopt inercept form is y=-x-1
Answer: +/- 0.018
All you have to do is plug the known values into the equation and evaluate it.
First, do the work under the square root sign. 0.77(1-0.77) / 2100 gives you a very small number. If you take the square root of that, you will have 0.0091.
The last step is to just multiply that by 2 and you will have 0.018

Answer:
4. 50.19°
5. 25.19°
Step-by-step explanation:
4. Reference angle = x°
Opposite = 6 units
Adjacent = 5 units
Thus,
(nearest hundredth)
5. Reference angle = x°
Opposite = 48 - 5.2 = 42.8 ft
Adjacent = 91 ft
Thus,
(nearest hundredth)b
