Answer
<u>2</u><u>.</u><u>5</u><u>6</u><u>m</u>⠀
Step by Step explanation:
⠀
Let AC be the 7 meters high Flagstaff
And BC be the tower
⠀
Let the height of BC = x
The height of AB will be (x + 7)m
⠀
∠ADB = 45° and ∠CDB = 15°
(as given in the question)
⠀
<u>By</u><u> </u><u>using</u><u> </u><u>trigonometry</u><u> </u><u>formula</u>

⠀
⠀
So tan 45 will be

⠀
⠀
And tan 15 will be

⠀
⠀
Using both Values of BD to find x
⠀

<u>The</u><u> </u><u>height</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>tower</u><u> </u><u>is</u><u> </u><u>2</u><u>.</u><u>5</u><u>6</u><u>m</u>
The question is asking you to find how much more quicky Annie is traveling on a bike compared to walking. We simply divide her biking speed by her walking speed to get a factor:

Then we convert this to a percent: 320 percent.
We can say that Annie is traveling 320 percent faster on a bike compared to walking.
I’m going to assume you know slope-intercept form. The work will be displayed below on my magnificent, college-ruled paper.
There are 2 orange marbles, 3 green marbles, & 5 purple marbles
two consecutives draws <em>without</em> replacement
Orange first, green second
Orange/total = 2/10, or 1/5
green/total - 1 = 3/9, or 1/3
1/5(1/3) = 1/15
There is a 1/15 chance of <em>Orange first, green second</em>
Both marbles are purple
Purple/total = 5/10, or 1/2
Purple/total = 4/9, or <em>44% chance of both being purple</em>
first is purple, the next is anything but purple
purple/total = 1/2, or 50% chance
(everything - purple)/total = 5/10, or 50% chance
1/2(1/2) = 1/4, or 25% chance of <em>first purple, then anything but purple</em>
hope this helps
Step-by-step explanation:
X- axis interception points of 2x² - 2, x = 0: None
y- axis interception point of 2x²-2, x=0:
Y Intercepts: (0, - 2)
