I say it’s c.150 because 6 hours is 300 then 5 hours is 250 so you’re subtracting 50 for 1 less hour, so 4 hours would be 200 that makes 3 hours 150

got it? hope that’s not too confusing

Suppose the wholesale price of a certain brand of medium-sized eggs p (in dollars/carton) is related to the weekly supply x (in
Mrrafil [7]

Answer:

1300

Step-by-step explanation:

We are given

x = 35

\frac{dp}{dt}=-0.05  [rate of change of price with time]

We want to find \frac{dx}{dt}, which is the rate at which supply is changing.

First, we need to implicitly differentiate the equation given:

625p^2-x^2=100\\1250p\frac{dp}{dt}-2x\frac{dx}{dt}=0

Here, we have what we need except for p. We find p when x = 35:

625p^2 - x^2 =100\\625p^2 - (35)^2 =100\\625p^2=1325\\p=1.46

Now, find dx/dt:

1250(1.46)(-0.05)-2(35)\frac{dx}{dt}=0\\-91.25-70\frac{dx}{dt}=0\\\frac{dx}{dt}=-1.30

In thousands, 1.30 * 1000 = 1300 cartons per week decrease

I need to find AB and DE​
MatroZZZ [7]

Answer:

AB = 21 and DE = 23

Step-by-step explanation:

Given 2 intersecting chords inside the circle then

The products of the measures of the parts of one chord is equal to the products of the measures of the parts of the other chord, that is

x(x + 13) = (x + 10)(x + 1) ← distribute parenthesis on both sides

x² + 13x = x² + 11x + 10 ← subtract x² + 11x from both sides

2x = 10 ( divide both sides by 2 )

x = 5

Hence

AB = x + 10 + x + 1 = 2x + 11 = (2 × 5) + 11 = 10 + 11 = 21

DE = x + x + 13 = 2x + 13 = (2 × 5) + 13 = 10 + 13 = 23
