dexar [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

There are approximately 3.2 \times 10^7 mosquitoes near each backyard pool.

The city has total number of pools 6.7 \times 10^{12}.

So the total mosquitoes will be : 3.2 \times10^7 \times6.7\times 10^{12}

So the total mosquitoes will be : 21.44 \times 10^{19}

So the total mosquitoes will be : 2.144 \times 10^{20}  :   Answer

Hope it will help :)

a meteorologist measures the angle of elevation of a weather balloon with the ground as 41. A radio signal from the balloon indi
Aneli [31]
Here you would use right triangle trig (SOH CAH TOA)
So first draw a right triangle. Imagine youre standing at the angle opposite the right angle which is the one on the ground.This angle is the 41°. Now Imagine the balloon is as the angle above the right triangle. Well since the balloon is 1503 m from his location this would be the hypotenuse. SInce we are trying to find the height (x) we would use sine since
sine = opposite/hypotenuse . Now lets solve make sure calculator is in degree mode:

sin41 = x/1503      multiply both sides by 1503 to cancel it out
1503sin41 = x        plug into calculator
x = 986.057 ft
The balloon is 986.057 feet above the ground.

So using standard form you convert the equation to 5x - 2y = -10 then use slope m of a line of the form Ax + By = C equals negative a over b. It would be a = 5 b = -2 m = -5/-2 m = 5/2. Have a good day the answer is 5/2
