The moon is 2.4 x 10^5 miles from earth. Assume the speed of the fastest spacecraft is 3.6 x 10^4 miles per hour. How many hours
alexgriva [62]

Answer:

t = 6.67 seconds

Step-by-step explanation:

Given that,

The distance of Moon from Earth, d=2.4\times 10^5\ miles

The speed of the spacecraft, v=3.6\times 10^4\ miles/hour

We need to find the time it take this spacecraft to fly to the moon from earth. Let the time is t.

We know that,

Speed = distance/time

t=\dfrac{d}{v}\\\\t=\dfrac{2.4\times 10^5}{3.6\times 10^4}\\\\t=6.67\ s

So, the required time is equal to 6.67 seconds.

The function f(x) = 2x + 210 represents the number of calories burned when exercising, where x is the number of hours spent exer
babymother [125]

Hey there!

When we say (f + g)(2), we are adding both functions together and plugging in 2 for x.

Since f(x) is equal to 2x + 210 and g(x) is equal to 2x + 125, (f + g)(x) is equal to (2x + 210) + (2x + 125).

That can be simplified to 4x + 335.

So, (f + g)(x) = 4x + 335.

Let's plug 2 in for x and solve.

(f + g)(2) = 4(2) + 335

Multiply.

(f + g)(2) = 8 + 335

Add.

(f + g)(2) = 343

The x value is consistent for the values of both equations, in both x is defined as the number of hours spent exercising.

So, (f + g)(2), which is 343, is the amount of calories burned and the calorie deficit on a diet when 2 hours are spent exercising.

Hope this helps!
