Answer:
Drone will take 0.25 hectare per minute to scan the area.
Step-by-step explanation:
By using unitary method,
A search and rescue drone takes 2 minutes to scan the area = 0.5 hectare.
Area scanned by the drone in 1 minute = [tex]\frac{\text{Total area scanned}}{\text{Total time taken}}[/tex]
= [tex]\frac{0.5}{2}[/tex]
= 0.25 hectare per minute
Therefore, drone will take 0.25 hectare per minute to scan the area.
A ladder is leaning against a wall. If the base of the ladder is 8ft from the wall and the ladder is 16ft long, how high up does it sit on the wall? Leave your answer in simplest radical form and do not include units.
Answer:
height = 13.86, or 8√3
Step-by-step explanation:
using the Pythagorean theorem:
h² = 16² - 8²
h² = 256 - 64
h² = 192
h = 13.86 ft or 8√3
Q. Which equation describes the line that passes
through the point at (-2, 1) and is perpendicular
to the line y = 1/3x + 5?
Answer:
Step-by-step explanation:
perp. -3
y - 1 = -3(x + 2)
y - 1 = -3x - 6
y = -3x - 5
Write the equation of each line. State its slope and y-intercept, if they exist.
Answer:
4. a) y=1x+2
b) y=0x
c) y=0x
d) y=1x+0
Step-by-step explanation:
The formula for slope intercept form is y=mx+b and the formula for slope is rise/run.
b= y intercept and m=slope.
4.b and 4.c do not cross the y intercept.

Step-by-step explanation:
Read John Muir's "Calypso Borealis" and answer the question. [1] After earning a few dollars working on my brother-in law's farm near Portage [Wisconsin], I set off on the first of my long lonely excursions, botanising in glorious freedom around the Great Lakes and wandering through innumerable tamarac and arbor-vitae swamps, and forests of maple, basswood, ash, elm, balsam, fir, pine, spruce, hemlock, rejoicing in their bound wealth and strength and beauty, climbing the trees, revelling in their flowers and fruit like bees in beds of goldenrods, glorying in the fresh cool beauty and charm of the bog and meadow heathworts, grasses, carices, ferns, mosses, liverworts displayed in boundless profusion. [2] The rarest and most beautiful of the flowering plants I discovered on this first grand excursion was Calypso borealis (the Hider of the North). I had been fording streams more and more difficult to cross and wading bogs and swamps that seemed more and more extensive and more difficult to force one's way through. Entering one of these great tamarac and arbor-vitae swamps one morning, holding a general though very crooked course by compass, struggling through tangled drooping branches and over and under broad heaps of fallen trees, I began to fear that I would not be able to reach dry ground before dark, and therefore would have to pass the night in the swamp and began, faint and hungry, to plan a nest of branches on one of the largest trees or windfalls like a monkey's nest, or eagle's, or Indian's in the flooded forests of the Orinoco described by Humboldt. [3] But when the sun was getting low and everything seemed most bewildering and discouraging, I found beautiful Calypso on the mossy bank of a stream, growing not in the ground but on a bed of yellow mosses in which its small white bulb had found a soft nest and from which its one leaf and one flower sprung. The flower was white and made the impression of the utmost simple purity like a snowflower. No other bloom was near it, for the bog a short distance below the surface was still frozen, and the water was ice cold. It seemed the most spiritual of all the flower people I had ever met. I sat down beside it and fairly cried for joy.
[4] It seems wonderful that so frail and lovely a plant has such power over human hearts. This Calypso meeting happened some forty-five years ago, and it was more memorable and impressive than any of my meetings with human beings excepting, perhaps, Emerson and one or two others. When I was leaving the University, Professor J.D. Butler said, "John, I would like to know what becomes of you, and I wish you would write me, say once a year, so I may keep you in sight." I wrote to the Professor, telling him about this meeting with Calypso, and he sent the letter to an Eastern newspaper [The Boston Recorder] with some comments of his own. These, as far as I know, were the first of my words that appeared in print.
[5] How long I sat beside Calypso I don't know. Hunger and weariness vanished, and only after the sun was low in the west I splashed on through the swamp, strong and exhilarated as if never more to feel any mortal care. At length I saw maple woods on a hill and found a log house. I was gladly received. "Where ha ye come fra? The swamp, that awfu' swamp. What were ye doin' there?" etc. "Mony a puir body has been lost in that muckle, cauld, dreary bog and never been found." When I told her I had entered it in search of plants and had been in it all day, she wondered how plants could draw me to these awful places, and said, "It's god's mercy ye ever got out."
[6] Oftentimes I had to sleep without blankets, and sometimes without supper, but usually I had no great difficulty in finding a loaf of bread here and there at the houses of the farmer settlers in the widely scattered clearings. With one of these large backwoods loaves I was able to wander many a long wild fertile mile in the forests and bogs, free as the winds, gathering plants, and glorying in God's abounding inexhaustible spiritual beauty bread. Storms, thunderclouds, winds in the woods—were welcomed as friends.

If angle 2 is 130°, what are the measures of 1, 3 and 4
Answer:
The missing are 8°, 16°, 24°.Let the missing angles be x, 2x, 3x.
X + 130° + 2x + 3x = 180°. (sum of angles is 180°)
6x + 130° = 180°
6x = 180°- 130°
6x = 50°
x = 50° ÷ 6
x = 8°
:. 2x = 8 × 2
16°

Find the lengths of the missing sides in the triangle. Write your answers as integers or as decimals rounded to the nearest tenth.
Answer:
[tex]x = 9.9[/tex]
[tex]y= 7[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Find x and y
Considering [tex]\theta = 45[/tex]
From the attached triangle, length x is the hypotenuse and length y is the adjacent
Solving for x
[tex]Sin\theta = \frac{Opp}{Hyp}[/tex]
[tex]Sin\theta = \frac{7}{x}[/tex]
So, we have:
[tex]Sin45 = \frac{7}{x}[/tex]
[tex]x= \frac{7}{Sin45 }[/tex]
[tex]x = \frac{7}{0.7071}[/tex]
[tex]x = 9.9[/tex]
Solving for y
Considering [tex]\theta = 45[/tex]
[tex]Tin\theta = \frac{Opp}{Adj}[/tex]
So, we have:
[tex]Tin45= \frac{7}{y}[/tex]
[tex]y= \frac{7}{Tan45}[/tex]
[tex]y= \frac{7}{1}[/tex]
[tex]y= 7[/tex]
The value of x and y is 9.9 and 7.
Calculation of the value:Since theta is 45 degrees
So, we know that
Sin theta = opp/hyp
Sin theta = 7 /x
x = 7 / 0.7071
= 9.9
Now the value of Y should be
Tin theta = opp/hyp
y = 7 \tan 45
= 7 /1
= 7
Therefore, we can conclude that The value of x and y is 9.9 and 7.

Rewrite each expression in factored form using the greatest common factor. 11. 16x+48 12. 28x+ 32y 13. 11w+hw pls help!!!
Answer:
16(x + 3)
4(7x + 8y)
w(11 + h)
Step-by-step explanation:
16x + 48
The greatest common factor of 16 and 48 = 16
Hence, expressing 16x + 48 in factored form:
16x + 48 = 16(x + 3)
28x + 32y
Greatest common factor of 28 and 32 = 4
Hence,
28x + 32y = 4(7x + 8y)
11w + hw
11w + hw = w(11 + h)

pythagorean theorem: FIND X
Answer:
X²=5²+12²
X²=25+144
X²=169
X²=13²
X=13
Answer:
x = 13
Step-by-step explanation:
The first step to finding x is to apply the numbers to the Pythagorean Theorem.
The formula for the Pythagorean Theorem is a^2 + b^2 = c^2.
1. Now we have to put the known values in place of the letters.
a = 12
b = 5
c = x
2. Since the formula is squaring a, b, and c, we have to square the numbers too.
a = 12^2
b = 5^2
c = x^2
12^2, or 12 squared, is 144.
5^2, or 5 squared, is 25.
3. Next we have to add those two numbers.
144 + 25 = 169
4. Lastly, we have to square root 169
√169 = 13
Therefore, your answer is 13.
Hope this Helps!
