The correct answer is B


These students do not represent the whole population of students, so the results of the survey will disproportionately recognize the opinion of the extracurricular students.

Graph the function f(x)=1/2 sqrt(x+1)
goldenfox [79]

The function is defined only if x+1 \geq 0 \iff x \geq -1. So, the leftmost point is x=-1, and we have


f(-1)=\frac{1}{2}sqrt(-1+1) = 0


So, the first point is (-1,0)


The three additional points seem arbitrary, so let's choose x=0,1,2. We have:


f(0)=\frac{1}{2}sqrt(0+1) = \frac{1}{2}


So, the second point is (0,\frac{1}{2})


f(1)=\frac{1}{2}sqrt(1+1) = \frac{\sqrt{2}}{2}


So, the third point is (1,\frac{\sqrt{2}}{2})


f(2)=\frac{1}{2}sqrt(2+1) = \frac{\sqrt{3}}{2}


So, the fourth point is (2,\frac{\sqrt{3}}{2})

during the winter months, freshwater fish sense the water getting colder and swim to the bottom of lakes and rivers to find warm
Jlenok [28]

Answer: 28 feet.


Step-by-step explanation:

Given: During the winter months, freshwater fish sense the water getting colder and swim to the bottom of lakes and rivers to find warmer water.

The total depth of the lake = 32 feet

Since, fish swims 7/8 of the depth, then the depth of lake to which the fish swim=\frac{7}{8}\times32\ feet

Since, 32\div8=4

therefore, \frac{7}{8}\times32=7\times4=28

Hence, the fish swim 28 feet in lake.
