Panel 1 is the answer choice<br><br> Panel 2 is the question
Ierofanga [76]
D is the midpoint of A and B
A = (0,s)
B = (r,0)

Add up the x coordinates to get 0+r = r. Then cut that in half to get r/2
Similarly, do the same for the y coordinates: s+0 = s ---> s/2

So the location of point D is (r/2, s/2)

Answer: Choice C

an initial population of 700 trout increases at an annual rate of 22%. Which exponential function models the trout population?​
REY [17]

Answer:

y=700(1.22)^{x}

Step-by-step explanation:

Let

y-----> the trout population

x----> the time in years

we know that

22\%=22/100=0.22

y=700(1+0.22)^{x}

y=700(1.22)^{x} ----->exponential function that models the trout population

stich3 [128]

Answer:

You can buy 7 waffle cones.

Step-by-step explanation:

Let sundae = x

Let waffle cones = y

4.25x + 3.75y ≤ 50

4.25 (5) + 3.75y ≤ 50

21.25 + 3.75y ≤ 50

3.75y ≤ 28.75

y ≤ 7.666666666

* round to the nearest whole to get 7
