Answer: 2,125 whales
because half of the ten whales in the sample were infected, then half of the population would likely be infected. 4,250/2=2,125
Answer:
(-infinity, 4]
Step-by-step explanation:
The range is the possible y values
The smallest that (x+3)^2 can be is zero
f(x) = 4 − 2(x + 3)^2
f(x) = 4 -2(0) = 4
This is the maximum value
As the square term gets bigger we are subtracting a larger amount and it will get more negative
Let x = infinity, x+3 = infinity and infinity ^2 = infinity and 2* infinity = infinity
f(x) = 4 - infinity
= -infinity
The range is -infinity to 4
the formula for the perimeter of a rectangle is
P= 2(L+W)
with L representing length and W representing width
since we have the perimeter and the length, we can plug the values into the equation to find W
346 = 2(92+w)
346 = 184 + 2W
162 = 2W
81 = W
the width of the field is 81 yards.
hope this helped!
Answer:
Step-by-step explanation:
we know that
The area of the shaded sections is equal to the area of the circle minus the area of the triangle
so
where
----> the radius is half the diameter
substitute
