Answer:
sorry in middleschool so cant help but if i did know i would love to help
Step-by-step explanation:
F(x)=-x2+5n
g(x)=-2n+15
A(x)=|g(x)-f(x)|=|x2-7n+15|
x2-7n+15>0 for every x (1)
A(x)=x2-7n+15
(1):
x2-7n+15=(x-3.5)^2-12.25+15=(x-3.5)^2+2.75 > 0
because for every x: (x-3.5)^2>=0
answer: A(x)=x2-7n+15
The answer is 128.5°
You multiply 180/pi by 257pi/360 and that gives you 128.5.
Answer:
x = 3
Step-by-step explanation:

Look at this like a right triangle with a height of 32 M and the angle at the base of 22 degrees
The distance from the boat to the lighthouse would be the base of the triangle
to find the base given the height and angle given the formula is
x = height / tan(angle)
x = 32 / tan(22)
x = 79.2 Meters
