Phoenix [80]3 years ago
3 0

Answer:

Step-by-step explanation:

Use the Pythagorean theorem to find the altitude.

h^2 = 9^2 - 6.4^2

h^2 = 40.04

h = 6.328

area = base * height/2

area = (2 * 6.4) * 6.328/2

area = 40.5 square units

I need help please thanks
strojnjashka [21]

Answer:

y = 1/2x + 0

You can see the slope is rising by 1 and running (to the right) by 2. This makes the slope, or rate of change, 1/2x.

There aren`t really calculations necessary to find the rate of change, but if you need more explaining please do ask, I`m happy to help

Answer:

65.3%

Step-by-step explanation:

what we want: p(2)+p(3)+p(4)

P(2)={5\choose2}*.4^2*.6^3\\P(3)={5\choose3}*.4^3*.6^2\\P(4)={5\choose4}*.4^4*.6\\P(2)+P(3)+P(4)= .6528

which equal 65.28%

which rounds to

65.3%
