Answer:
I. 5
Step-by-step explanation:
- 140° and 8x° are on the straight angle and they are both equal 180°
to find the value of x:
140 + 8x = 180
8x = 180 - 140
8x = 40
x = 40/8
x = 5
Answer:
h=2.69 m
Step-by-step explanation:
Ep=m×g×h
1=0.038×9.8×h
1/0.038×9.8=h
1/0.3724=h
2.69=h
To determine the inverse of a function, we first write the parent function in terms of y. So, in this part the x would be isolated to one side of the equation. Then, with the new form of the parent function, we switch the x into y and y to x. The new function would be the inverse function. For the given function, we do as follows:
<span> y=-4/x + 1
y - 1 = -4/x
x ( y - 1 ) = -4
x = -4 / (y -1)
Replacing x into y and y into x,
</span>y = -4 / (x -1)
<span>Therefore, the inverse is y=-a/x-b where a = 4 and b = 1.</span>
So there are a couple of different ways to write it but I find the easiest to be 28/9 or 3 1/9
