Answer:
the 8augmentat in DE pad quatpesa
Answer:
Step-by-step explanation:
From the given right angle triangle,
The unknown side represents the hypotenuse of the right angle triangle.
With m∠x as the reference angle,
the adjacent side of the right angle triangle is 7.8
the opposite side of the right angle triangle is 8
To determine m∠x, we would apply
the Tangent trigonometric ratio.
Tan θ, = opposite side/adjacent side. Therefore,
Tan x = 8/7.8 = 1.026
x = Tan^-1(1.026)
x = 45.7° to the nearest tenth
Answer:
8
Step-by-step explanation:
2n-5=11
2n=11+5
2n=16
n=8
The given equation is -3x²+240x-800
The maximum of the function is given when

where a and b are the constant of a quadratic form ax²+bx+c
We then have
a = -3
b = 240
Substitute these values into the maximum/minimum formula we have

Which means that the maximum profit is obtained when the number of refrigerators produced is 40 items a day
The maximum profit is
p = -3(40)²+240(40)-800 = $4000
