Lauren is at a friend's home that is several miles from her home. She starts walking at a constant rate in a straight line towar
DaniilM [7]

a.

Lauren was 10 miles away from her house when he started.

Since the expression for Lauren's distance from her house, d = -2t + 10, to determine the number of miles away from his house that Lauren starts, we input t = 0, since this is the time Lauren starts walking.

So, with t = 0, d = -2t + 10

= -2(0) + 10

= 0 + 10

= 10 miles.

So, Lauren was 10 miles away from her house when he started.

b.

Lauren was moving at a rate of -2 mph towards her house.

To find how fast Lauren was moving towards her house, we differentiate d with respect to t.

So, dd/dt = d(-2t + 10)/dt

= d(-2t)/dt + d(10)/dt

= -2 + 0

= -2 mph

So, Lauren was moving at a rate of -2 mph towards her house.

c.

The rate is negative because her distance towards her house is decreasing

The rate is negative because her distance towards her house is decreasing since she is moving towards her house.

d.

Lauren is 2 miles away from her house after 4 hours

To find this, we input t = 4 into the equation for d.

So, d = -2t + 10

= -2(4) + 10

= -8 + 10

= 2 miles.

So, Lauren is 2 miles away from her house after 4 hours

The Mars Cereal Company has two different cereal boxes for Mars Cereal. The large box is 8 inches wide, 11 inches high, and 3 in
lubasha [3.4K]

Answer:

a)90  square inches

b)104 cubic inches

Step-by-step explanation:

Dimensions of the bigger box

W= 8 in

H=11 in

D= 3 in

Dimensions of the smaller box

w= 6 in

h= 10 in

h= 2.5 in

therefore, difference in the area of the cupboard

=2[ WH+HD+WD] - 2[wh+hd+wd]

= 2[8*11+11*3+8*3]- 2[6*10+10*2.5+6*2.5]

=290- 200= 90 square inches

volume of the large cupboard = WHD= 8*11*3= 264 cubic in

volume of the small cupboard= whd= 6*10*2.5= 150 cubic in

therefore,  264-150= 114 cubic in more cereal does the large box hold than the small box
