If you drew out this line segment with the points in the order we are given them, the segment would be labeled as a, b, c, d in that order. We are given a measure for ab, and we are also given a measure for bd with c being ignored for a minute. The entire length of the segment can be found by adding ab and bd. 6 + 23 = ad and ad = 29. So the length of the whole segment is 29. We have the length of cd given to be equal to ab, so cd = 6. ab + bc + cd = ad and we are looking for bc. Since we have the other lengths and the length of the whole segment, we fill in accordingly: 6 + bc + 6 = 29. Solving for bc we get bc = 17.
Answer:500 on top of the water and 9,500 below
Step-by-step explanation:
30 times 40= 120
120 divided by 2= 60.
The answer is 60 feet.
Answer:
<em>Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D</em>
Step-by-step explanation:
Take a look at the procedure below;
First simplify f ( x ) = - 4 * ( 8 )^x, such that it is ⇒
f ( x ) = - 2^2 * 8^x,
f ( x ) = - 2^2 * ( 2^3 )^x,
f ( x ) = - 2^2 * 2^3x,
f ( x ) = - 2^2 + 3x,
Now if we take a look at the domain we can see that it has no undefined points nor domain constraints, thus;
- ∞ < x < ∞
However, the range of the function is present in the form - c * n^ax + b, where f ( x ) < k, and k = 0;
f ( k ) < 0, y < 0
<em>Solution; Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D</em>

Answer:
- f(0) ≈ 22
- f(1) = 10
- f(b) ≈ -8
- f(c) = 0
- f(d) 24
Step-by-step explanation:
This takes graph-reading one step further. You get to estimate the y-value without benefit of minor grid lines. You must mentally divide the 10-unit distance between grid lines into equal spaces. Then estimate how many of those spaces lie between the point and the nearest grid line.
You can do this more precisely by drawing a diagonal line across the grid from one major grid intersection to one that is (5, 1) or (5, -1) major grid points away. Where that line crosses the intermediate grid lines, the vertical measure will be some multiple of 1/5 of the vertical difference between grid points. For example, a line from (0,20) to (5,30) will cross at (1,22), (2,24), (3,26), and (4,28). You can use these reference points to identify the y-values at f(0) and f(d).
Here's our eyeball estimate:
- f(0) ≈ 22
- f(1) = 10
- f(b) ≈ -8
- f(c) = 0
- f(d) 24
