Answer:
= 70 Meters
Step-by-step explanation:
We can use the sine rule as follows:
Angle ABC=180-(70.5+38.833)
=70.667°
Using the sine rule and sides AB, AC and angles ABC and ACB:
b/Sin B=c/Sin C
Replacing with the values above we get:
AC/Sin ABC= AB/Sin ACB
105.6/Sin 70.667=AB/Sin 38.833
AB=(105.6 Sin 38.833)/Sin 70.667
=70.17 meters
The distance between the two points to the nearest meter is 70 meters
Answer:
9+(4)
Step-by-step explanation:
Answer:
5 < x < ∞
-∞ < x < 0
2 < x < ∞
Step-by-step explanation:
Given function is 
+ 3
+ 1.
To, Calculate where the function is increasing or decreasing,
we have to calculate the derivative of the function,
so,
f'(x) = -3 + 6x.
Equating the f'(x)= 0 , we get
x(-3x + 6) = 0
So, f'(x) will be zero at x = 0 and x = 2.
f(x) will be decreasing in the interval where f'(x) will be negative.
now as the coefficient of f'(x) is negative it will be negative between
the interval -∞ < x < 0 and 2 < x < ∞.
Options which lie in these intervals only are
5 < x < ∞
-∞ < x < 0
2 < x < ∞
Given:
13/8
First you have to see how many times 8 can go into the number 13. If you look, 8 can only go into 13 one time, leaving 5 left over.
13-8 = 5
1 with 5 left over
(Rather than writing 8/8, you must simplify to 1 to make it less redundant)
Since there is 5 left over from 8, you would then place it into the numerator place to get:
1 5/8
I hope this helps!
