Answer:
53.52°
Step-by-step explanation:
The cosine function relates the angle to the sides shown:
Cos = Adjacent/Hypotenuse
cos(x°) = (22 ft)/(37 ft) = 22/37
The inverse cosine function is used to find the corresponding angle.
x° = arccos(22/37) ≈ 53.52°
Answer:
(Yes, "5" is a polynomial, one term is allowed, and it can be just a constant!) 3xy-2 is not, because the exponent is "-2" (exponents can only be 0,1,2,...)

We conclude that after 50 days, there will be 67 lily pads.
<h3>how many will there be after 50 days?</h3>
We know that the number increases by 25% every 10 days.
In 50 days we have 5 groups of 10 days, so there will be five increases of 25%.
We know that the initial number is 22 lily pads, if we apply five consecutive increases of the 25% we get:
N = 22*(1 + 25%/100)*...*(1 + 25%/100%)
( the factor (1 + 25%/100%) appears five times)
So we can rewrite:
N = 22*(1 + 25%/100%)⁵
N = 22*(1 + 0.25)⁵ = 67.1
Which can be rounded to the nearest whole number, which is 67.
So we conclude that after 50 days, there will be 67 lily pads.
