Answer:

See Explanation

Step-by-step explanation:

Given

Price = 29.50 + 13.50(p - 2)

The question has missing details. However, I will solve on a general term.

A possible question could be to find the cost of purchasing (say 10 bottles).

To do this, we simply substitute 10 for p.

So:

Price = 29.50 + 13.50(p - 2)

Price = 29.50 + 13.50(10 - 2)

Price = 29.50 + 13.50 * 8

Price = 29.50 + 108

Price = 137.50

i.e. $137.50 for 10 pint bottles

Another possible question is to calculate the number of pint bottles that amount to (say $70).

To do this, we simply substitute 70 for Price.

So:

Price = 29.50 + 13.50(p - 2)

70 = 29.50 + 13.50(p - 2)

Collect like terms

70 - 29.50 = 13.50(p - 2)

40.5= 13.50(p - 2)

Divide both sides by 13.50

3= p - 2

Add 2 to both sides

3 + 2 = p - 2 + 2

5 = p

p = 5

i.e. $70 will buy 5 pint bottles

Help me with this please!!!!!!!!!

Answer:

d = 17.58

Step-by-step explanation:

d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2

P1(0, 0, 0) P2(8, 7, 14)

Substitute the values in the above equation and you will get

d = √(8 - 0)^2 + (7 - 0)^2 + (14 - 0)^2

= √(64 + 49 + 196)

= √309

= 17.58

A flying squirrel jumped from a tree 11 feet in the air at the initial velocity of 9 ft./s the equation H equals negative 2T squ
Nady [450]

Answer:

The squirrel maximum height (h) = 21.125 ft

Step-by-step explanation:

The objective of this question is to determine the squirrel's maximum height.

Given that:

h = -2t² + 9t + 11

Differentiating h with respect to t, we get;

\dfrac{dh}{dt}= -4t +9

At the time dh/dt = 0, the velocity is maximum

Thus;

-4t = -9

4t = 9

t = 9/4

t = 2.25 seconds

From;

h = -2t² + 9t + 11

h = - 2(2.25)² + 9(2.25) + 11

h = - 10.125 + 20.25 + 11

h = 21.125 ft
