Question 2

Mathematics
1 answer:
Anni [7]3 years ago
6 0

Answer:

M = (9,3)

Step-by-step explanation:

Given

(x_1,y_1) = (4,8)

(x_2,y_2) = (14,-2)

Required

Find the midpoint (M)

The midpoint is calculated as follows:

M = (\frac{1}{2}(x_1+x_2),\frac{1}{2}(y_1+y_2))

Substitute values for x's and y's

M = (\frac{1}{2}(4+14),\frac{1}{2}(8-2))

M = (\frac{1}{2}(18),\frac{1}{2}(6))

M = (\frac{1}{2}*18,\frac{1}{2}*6)

M = (9,3)

<em>Hence, the midpoint is (9,3)</em>

The biomass B(t) of a fishery is the total mass of the members of the fish population at time t. It is the product of the number
LenKa [72]

Answer:

174.8 guppies.g/week

Step-by-step explanation:

B(t) = N(t)M(t)

Utilizing the product rule of derivative

\frac{d(AH)}{dt} = A\frac{dH}{dt} + H\frac{dA}{dt}

Applying the rule to B(t) = N(t)M(t)

\frac{d(B(t))}{dt}   = N(t)\frac{d(M(t))}{dt} + M(t)\frac{d(N(t))}{dt}

from the question

t=4 weeks, N(4) = 820 guppies

d(N(4))/dt = 50 guppies/week

m(4) = 1.2g

d(M(4))/dt = 0.14g/week

\frac{d(B(t))}{dt}   = N(t)\frac{d(M(t))}{dt} + M(t)\frac{d(N(t))}{dt}\\\\= 820(0.14) +  50 (1.2) =  174.8 guppies.g/week
