<h3>
Answer: 2.244 seconds</h3>
Explanation:
The x coordinate of the left peak point is x = 1.870, and its neighboring peak point has an x coordinate of x = 4.114
The difference is 4.114 - 1.870 = 2.244
The period is 2.244 seconds, which is the time it takes to go from one peak to another adjacent. This is the same as going from one valley point to a neighboring valley point.
Answer:
$3.50 per pound
Step-by-step explanation:
Divide 42 by 12 or 31.5 by 9 and you get 3.5. In money, that is $3.50
Answer:
x≥ -4
Step-by-step explanation:
9 + 9(x + 7)≥ 36
Subtract 9 from each side
9 -9+ 9(x + 7) ≥ 36-9
9(x + 7) ≥ 27
Divide each side by 9
9/9(x + 7) ≥ 27/9
x+7≥ 3
Subtract 7 from each side
x+7-7 ≥ 3-7
x≥ -4
3 miles each day for x days is 3x
5 miles each day for y days is 5y
Frank ran at least as many miles as Latoya is 3x >/= 5y
It's C because for the perpendicular line, you need to construct cross points to draw it through.
- you start by drawing a random circle with F as the center, just as long as it intersects line DE
- Then you use the intersections of that circle to draw new circles starting at F.
- These new circles intersect at F and another point below DE.
- You draw the perpendicular line through F and the other point.
