Answer:
t=152 days (in radians)
Step-by-step explanation:
W(t)models the daily water level at a pond in Arizona, t days after the hottest day of the year. (t is entered in radian)
We want to determine the first time,t at which the water level is 30cm.
When W(t)=30
Answer:
A(x) = -2X² + 600X
Step-by-step explanation:
Area = X · Y
Perimeter = 2X + Y = 600
Y = 600 - 2X
A(x) = X · (600 - 2X) = 600X - 2X²
A(x) = -2X² + 600X
if you want to maximize area:
A'(x) = -4X + 600 = 0
600 = 4X
X = 150
Y = 600 - (2 · 150) = 600 - 300 = 300
Area = 150 · 300 = 45,000 ft²
53 x 53 - 32 x 32 / 61 x 61 - 44 x 44
2809 - 1024 / 3721 - 1936
Then subtract
1785 / 1785 = 1
The answer is 1. So the fraction is a whole number
Hope this helps
Answer:
- y = x² + 4
- x = √(4-y)
- x² - y = -4

Mark as brainliest = 10 thanks
1 thanks to me = 2 thanks
This answer would be letter C because if you simplify 49/56 divided by seven you get a grand total of 7/8.
