3. Mr. Matho has a garden in the shape of an equilateral triangle, He has planted a tree in each corner
of his garden; an oak tree, a maple tree, and a pine tree. In order to water his garden, he decides
that the best place to put a sprinkler would be in the middle of the garden, so it would be equidistant
from all three trees. If the perimeter of his garden is 36 m and the sprinkler is 2-3 m from the
fence joining the oak and maple tree, how far away is the sprinkler from any one of the trees?
Answer:
The distance the sprinkler is away from any one tree is 6.32 m if it is 2 m from the fence and 6.71 m if it is 3 m from the fence.
Step-by-step explanation:
Since the perimeter of the triangle P = a + b + c where a, b and c are the length of sides. Since the triangle is an equilateral triangle, a = b = c. So,
P = 3a
a = P/3
Since the perimeter = 36 m,
a = 36 m/3 = 12 m.
Since the sprinkler is 2 m from the fence joining the oak tree and maple tree, thee line perpendicular from the sprinkler to the fence is thus 2 m. This line cuts the side at the midpoint of the fence which is 12 m/2 = 6 m.
Since this is now a right-angled triangle, we now use Pythagoras' theorem to find the distance from the sprinkler to each tree which is
L = √[(2 m)² + (6 m)²]
= √[ 4 m² + 36 m²}
= √40 m²
= 2√10 m
= 6.32 m
If the fence is 3 m from the sprinkler, the distance
L = √[(3 m)² + (6 m)²]
= √[ 9 m² + 36 m²}
= √45 m²
= 3√5 m
= 6.71 m
So, the distance the sprinkler is away from any one tree is 6.32 m if it is 2 m from the fence and 6.71 m if it is 3 m from the fence.

How do you write 2x^5-9x^4-2x^2+10 in standard form?
Answer:
[tex]2x^5-9x^4+0x^3-2x^2+0x+10[/tex]
Step-by-step explanation:
A polynomial is in standard form when its terms are ordered from highest to lowest degree.
If the polynomial is missing terms, it must be completed by setting their coefficients to 0.
The given polynomial is:
[tex]2x^5-9x^4-2x^2+10[/tex]
The terms are ordered, but it's incomplete. The terms with exponent 3 and 1 must be included with zero coefficient.
Thus the polynomial in standard form is:
[tex]\boxed{2x^5-9x^4+0x^3-2x^2+0x+10}[/tex]

Answer:
$125
Step-by-step explanation:
To solve for one ticket divide 75 by 3 to get 25. Then to solve for 5 multiply 5 x 25 to get 125. So 5 tickets cost $125.
Hope that helps and have a great day!
Answer:
$125
Step-by-step explanation:
75 divided by 3 = 25
this means that the cost of one ticket is $25
so now all we need to is multiply $25 by 5 = $125

(60)x = 1, what are the possible values of x? Explain your answer.
Answer:
[tex]\frac{1}{60}[/tex]
Step-by-step explanation:
Problem:
The possible values of x in the equation (60)x = 1;
Solution:
Such a problem like this in which the highest power of the unknown is 1 will have just one solution.
60x = 1
To solve this, we take the multiplicative inverse of 60;
the multiplicative inverse of 60 = [tex]\frac{1}{60}[/tex]
Use this inverse to multiply both sides of the expression;
[tex]\frac{1}{60}[/tex] [tex]x[/tex] 60x = 1 x [tex]\frac{1}{60}[/tex]
x = [tex]\frac{1}{60}[/tex]
Describe a sequence of transformations that take isosceles trapezoid T to its image T'
Answer:If you rotate trapezoid BEFG counter clockwise 90° then reflected across pointy you will have the image above
Step-by-step explanation:
Transformation involves changing the position of a shape
The transformation from T to T' is a 90 degree counterclockwise
From the figure, we can see that:
The angle between isosceles trapezoid T and its image T' is a right-angle (i.e. 90 degrees)Figure T' is at the right of TThis means that:
A 90 degree counterclockwise through point D will take trapezoid T to T'
Hence, the required transformation is a 90 degree counterclockwise through point D

How much greater is (2^3)^2 than 2^3 x 2^2
Answer:
(2^3)^2/2^3X2^2 = 6/4 = 3/2
Step-by-step explanation:
(2^3)^2 = 6^2 = 36
2^3 X 2^2 = 6 X 4 = 24
Answer:
(2^3)^2 is 32 greater than 2^3 * 2^2
Step-by-step explanation:
(2^3)^2 = 2^(3 * 2) = 2^6 = 64
2^3 * 2^2 = 8 * 4 = 32
Difference:
64 - 32 = 32
Answer: (2^3)^2 is 32 greater than 2^3 * 2^2

what is the difference between the mean and the median of the set ( 3 ,8 ,10 ,15)
Answer:
You can think of the mean being acually mean because you have to do more work. When solving for the mean you add all the answers together then divide by the amount of numbers you have. For example, you have the numers (1, 2, 3) add them together (1+2+3) to get 6 then divide by 3 (6/3) to get a mean of two. The median is also fairly easy to remember. You line your numbers up least to greatest, left to right. and mark one off of each side at a time. If you have a even amount of numbers and reach the center, you add the two centers together then divide by to to get the median. If you have an odd amount of numbers, there should be one in the exact center left over.
Step-by-step explanation:
Mean) 3+8+10+15=36, 36/4=9 ANSWER=9
Median) 8+10=18, 18/2=9 ANSWER=9
In the case, the mean and median are the same and depending on context you could choose either method. It also helps that there is no outlyer. If there were on I would recomend finding the median.

It’s for algebra class please help my teacher is really strict but okay please thank u a lot
Answer:
The equation is true/ or an identity
Step-by-step explanation:
Plug in 7 for x, you get
2(7)+3=17
14+3=17
17=17
Answer:
14+3=17or(2*7) +3=17basically 17=17Step-by-step explanation:
2x+3=17 and x =7
Let's Substitute:(Because the variable is x and we have a value for it which is 7)(Bold and underlined is where the variable is in the equation)Since x is equal to 7 we are going to substitute it in the equation.
So: (2*7) +3=1714+3=17I think this is the answer since already having the value of x is an answer please let me know if I am wrong or answered incorrectly so I can change my answer or let everyone know its wrong so it can be deleted.
