5. A submarine is searching for underwater features. It is accompanied by a small At one time the aircraft is 200 m above the surface, the submarine is 55 m below
aircraft and an underwater robotic vehicle,
the surface, and the underwater robotic vehicle is 227 m below the surface
What is the difference in height between the submarine and the aircraft?
1.
2. What is the distance between the underwater robotic vehicle and the
submarine?

The required difference is 255 m .

Step-by-step explanation: Since we have given that

Distance at which the aircraft is above the surface = 200 m

Distance at which the submarine is below the surface = 55 m

Above the surface is represented as positive number i.e. (+) 200 m

Below the surface is represented as negative number i.e. (-) 55 m

Hence, the required difference is 255 m .

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
