Distance equals velocity times time.

d=vt, we are told that velocity is 9.5 mph so

d=9.5t  in 3 hours:

d=9.5*3=28.5mi

So it is the one on the bottom left.

The diagram shows a 7cm x 6cm rectangle-based pyramid all the diagonal sides - TA TB TC and TD are length 10cm M is the midpoint
dedylja [7]

Given:

The base is a rectangle of dimension 7 cm×6 cm.

The length of each diagonal side = 10 cm

To find the height of MT.

Formula

By Pythagoras theorem we get,

h^{2} = l^{2}  + b^{2}

where, h be the hypotenuse

b be the base and

l be the height.

Now, in this diagram,

The perpendicular distance of M from BC = 3 cm

Slant height = 10 cm

Taking, b = 3 and h = 10 we get,

10^{2}  = l^{2} + 3^{2}

or, l^{2} = 10^2-3^2

or, l = \sqrt{100-9}

or, l = 9.5

Hence,

The height of MT is 9.5 cm.

If you start at 89 degrees and it decreases 5% each hour what would it be at in 3 hours
PSYCHO15rus [73]

Answer:

A = 76.3 degrees after 3 hours

Step-by-step explanation:

An exponential function is needed here:

A = P(1 - 0.05)^3, where this (1 - 0.95) reflects a DECREASE of 5%/hour.

Then:  A = (89 degrees)(0.95)^3, or

           A = 76.3 degrees after 3 hours
