Aweather balloon is at an altitude where the temperature is 3º c. the balloon ascends 900 ft with a decrease in temperature of 5º c. the balloon then ascends again with a decrease in temperature of 3º c. what is the final temperature?

Answer is -5°C.

Step-by-step explanation:

Initial temperature = 3°C

First decrease in temperature = 5°C

Second decrease in temperature = 3°C

Balloon ascend  = 900 ft

Total change in temperature = 3-5-3 = -5

Thus final temperature = -5°C

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
