139 + 30d = 13 + 51d
139 - 13 = 51d - 30d
126 = 21d
126/21 = d
6 = d
now lets check..
139 + 30d = 139 + 30(6) = 319
13 + 51d = 13 + 51(6) = 319
so on day 6, they will both cost $ 319
The length x of a diagonal support, to the nearest tenth of a foot?
x≈ 13 feet
Cuz I said so
<span>Answer: A) exponential, because there is a relatively consistent multiplicative rate of change

temperature thrice. If you compare time=0 until time=30, you will get this table
t(10)- t(0)= 180-200= -20
t(20)-t(10)= 163-180= -17
t(30)-t(20)= 146-163= -17
</span>t(40)-t(30)= 131- 146= -15
t(50)-t(40)= 118-131= -13
t(50)-t(40)= 107-118= -11
There is something weird about the 2nd and 3rd value because it was same -17., but there seems to be a +2 change to the difference. So, the graph would be exponential with a <span>relatively consistent multiplicative rate of change</span>
(24.95 * 3) + 0.27x < 100
74.85 + 0.27x < 100
0.27x < 25.75
plug those in and you should get it :)
The <em><u>correct answer</u></em> is:
Without changing the span on the compass, place the compass point on one endpoint of the diameter and draw a full circle.
Explanation:
The steps to construct an inscribed equilateral triangle using the diameter are:
1. Place your compass point on the paper and draw a circle. Be sure to keep the compass set at the same width.
2. Using a straightedge, draw the diameter of the circle.
3. With the compass still set to the same width, place the compass point on one endpoint of the diameter and draw a full circle.
4. Draw segments connecting the points of intersection of the two circles and connecting each of these points to the opposite end of the diameter (the one <em>not</em> used as the center of the circle). This forms our triangle.
