By the power of Trigonometry!
We know the angle is 22*. The height of the ramp is on the OPPOSITE side of the angle. The known length of 32 ft is the ADJACENT side of the angle.
Q: Which trig function relates OPP and ADJ?
A: It's tangent!
tan(angle) = opposite / adjacent
So, we can say that
tan(22*) = opposite / 32
32*tan(22*) = opposite
With a calculator (make sure it is in degree mode!):
32*0.404 = opposite
12.928 ft = opposite
The height is 13 ft.
Answer:the 24 for 1.19 is the better deal
Step-by-step explanation:
1. 1.19 ÷24 =4.95
2.2.89÷36=8.5
3. It cost less for 1 can than the 8.5 dollar can.
The formula you can use for this is y=2/3×-5
Where the y is the cost of cats food and x is the cost of the dogs food
We can use a graphing tool to check f(x) and g(x)
They intersect at two points
x = 0.467 (aprox),
y = 1.67and
x = 3 ,
y = 27
