I would love to help you but there is no way to do a midpoint on brainly,
Answer:
I'm not 100% sure however I believe it would be x + 7x
Step-by-step explanation:
You start with what u have and then every week u get $7 each week. So I think this would be the best option however if it isnt right then I'm very sorry.
Hope this helps!
Answer:
1. The value of x is 9.4.
2. The value of y is 17.7.
Step-by-step explanation:
The following data were obtained from the question:
Angle θ = 32°
Hypothenus = y
Opposite = x
Adjacent = 15
1. Determination of the value of x.
The value of x can be obtained as follow:
Angle θ = 32°
Opposite = x
Adjacent = 15
Tan θ = Opposite /Adjacent
Tan 32° = x/15
Cross multiply
x = 15 × Tan 32°
x = 9.4
Therefore, the value of x is 9.4
2. Determination of the value of y.
The value of y can be obtained as follow:
Angle θ = 32°
Hypothenus = y
Adjacent = 15
Cos θ = Adjacent /Hypothenus
Cos 32° = 15/y
Cross multiply
y × Cos 32° = 15
Divide both side by Cos 32°
y = 15/Cos 32°
y = 17.7
Therefore, the value of y is 17.7.
I'll use subscript notation for brevity, i.e. .
By the chain rule,
We have
and
When , we have
and the partial derivatives take on values of
So we end up with
Answer:
x = ,
Step-by-step explanation:
First, isolate the absolute value:
5|2x - 7| = 20
divide both sides by 5:
|2x - 7| = 4
break into 2 equations:
2x - 7 = 4, 2x - 7 = -4
solve both equations and collect solutions:
2x = 11, 2x = 3
x = ,
