Answer:
Step-by-step explanation:
2n + 1 = 157
2n = 157 - 1
2n = 156
n = 156/2
n = 78
Answer:
127 square ft
Explanation:
The formula to find the area of a circle with a know circumference is: C^2/4 π.
40^2 is 1600 and 4 times pi is 12.56. Divide 1600 by the 12.56 and you will get your area of 127.39. The answer is 127 square ft after rounding to the nearest square foot.
If the angles of the triangle are 50, 90, 40 degrees, then only 1 triangle can be made. Because if you change the sides, the angles would change

F(x)= ∫ln²x/x dx= ∫ln²xd(lnx) cause d(lnx)= (lnx)'dx=1/x dx
= ln³x/3 +C with C is constant
In addition, we have f(2)=6, so we have 6=ln³2/3+C
or C= 6- <span>ln³2/3
And f(x)= </span>ln³x/3+ <span> 6- </span><span>ln³2/3</span>
1 mile is 5,280 ft, and 1 second has 1,000,000 microseconds.
So 186,000 miles per second multiplied by 5,280 feet per mile gives 982,080,000 feet per second.
Dividing this value by 1,000,000 microseconds per second gives the final answer of 982.08 feet per microsecond.
