Use long division to determine the decimal equivalent of 5 over 9. 0 point 3 bar 0 point 4 bar 0 point 5 bar 0 point 6 bar
1 answer:
Answer:
Option 3 - 0 point 5.
Step-by-step explanation:
Given : Decimal equivalent of 5 over 9.
To find : Use long division to determine the decimal?
Solution :
We have to divide 5 by 9,
Step 1 - Divide 5 by 9 as it is not divisible put a decimal and 0 after 5,
Step 2 - Now, divide 50 by 9 the quotient is 5 and remainder is 5.
Step 3 - Again put 0 and divide the number repeat the process until the remainder is not zero.
We have done the calculation up to 3-decimal place.
So,
Approximately,
So, Option 3 is correct.
Refer the attached figure for calculation.

length of the guy wire: 49.056
Step-by-step explanation:
here are the steps
If your directrix is a "y=" line, that means that the parabola opens either upwards or downwards (as opposed to the left or the right). Because it is in the character of a parabola to "hug" the focus, our parabola opens upwards. The vertex of a parabola sits exactly halfway between the directrix and the focus. Since our directrix is at y = -2 and the focus is at (1, 6) AND the parabola opens upward, the vertex is going to sit on the main transversal, which is also the "line" the focus sits on. The focus is on the line x = 1, so the vertex will also have that x coordinate. Halfway between the y points of the directrix and the focus, -2 and 6, respectively, is the y value of 2. So the vertex sits at (1, 2). The formula for this type of parabola is where h and k are the coordinates of the vertex and p is the DISTANCE that the focus is from the vertex. Our focus is 4 units from the vertex, so p = 4. Filling in our h, k, and p:
. Simplifying a bit gives us
. We can begin to isolate the y by dividing both sides by 16 to get
. Then we can add 2 to both sides to get the final equation
, choice 4 from above.
