Answer:
5√3
Step-by-step explanation:
Thanks to the given information we can say that the smallest leg is 5 because the triangle is half of an equaliteral one.
for the same reason we can say that x is 5√3 that is the simplest from of the result of the Pytaghorean theorem

Answer:
a. 12
b. 15
c. (2, -2.5)
Step-by-step explanation:
a. The points lie on a horizontal line, so the distance between them is the difference of their x-coordinates: 4 -(-8) = 12 units.
__
b. The length BD is the diagonal of the rectangle. Its length is given by the distance formula as ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((-8 -4)^2 +(-7 -2)^2) = √((-12)^2 +(-9)^2) = √(144 +81) = √225
d = 15
The distance between B and D is 15 units.
__
c. The midpoints of AC and BD are the same:
(A +C)/2 = ((-8, 2) +(4, -7))/2 = (4, -5)/2 = (2, -2.5)
(B +D)/2 = ((4, 2) +(-8, -7))/2 = (4, -5)/2 = (2, -2.5)
Point (2, -2.5) can be used to locate the lake.

Answer:
The area is about 25/2 inches^2
Step-by-step explanation:
You are given an isoceles triangle; the sides equal to each other are radiuses of the circle G. They are both 5 inches in length.
The angle between the two equal sides is equal to 88 degrees.
To find the height of the triangle, draw a line perpendicular to GH and solve for the lengths of the sides.
sin(88) = x/5
5sin88 is about 5 it is (4.99695)
Multiply the side length GH (5) and the solved height and divide by two;
The area is about 25/2 inches^2
Compare. Use <, >, and =.

Applying the 30-60-90 Theorem, Solve this.
Answer:
'y' would be 24
'x' would be 12[tex]\sqrt{3}[/tex]
Step-by-step explanation:
the ratio of sides in a 30-60-90 triangle is, respectively, 1 : [tex]\sqrt{3}[/tex] : 2
so the side across from the 60 degree angle is [tex]\sqrt{3}[/tex] times the side of the 30°
the side across from the 90 degree angle is double the side of the 30°
so in this problem 'y' would be 24 and 'x' would be 12[tex]\sqrt{3}[/tex]

What is the 18th term of the arithmetic
sequence 2,-2.-6.-10....?
F-72
H -68
WG -70
J -66
Answer:
J
-66
Step-by-step explanation:
a1 = 2
n = 18
d = - 4
a18 = a1 + (n - 1) * d
a18 = 2 + (18 - 1)*(-4)
a18 = 2 + 17*-4
a18 = 2 - 68
a18 = -66

C. y = –2x2
D. y = –3x2
Answer:
D. y = –3x2
Step-by-step explanation:
Answer:
y = -3x^2
Step-by-step explanation:
A quadratic function has a leading coefficient which determines its width. When |a| < 1 the graph is wider. When |a| > 1 the graph is narrower. This means y = -3x^2 is the narrowest graph since 3 is the greatest.

Rowena and Arlene are going to make a triangular path in her garden. The sides will be 20 feet, 36 feet, and 18 feet. What is the total length of the path? Answer the questions that follow using AGONSA.
Answer: 74feet
Step-by-step explanation:
In this case, to calculate the total length of the path, we have to find the perimeter of the shape which is a triangle.
It should be noted that the perimeter of a triangle is the addition of all of its sides. The sides given here are 20 feet, 36 feet, and 18 feet. Therefore, the total length will be:
= 20ft + 36ft + 18ft
= 74ft
The perimeter of a triangle is the sum of all sides of the triangle. Then the path length is 74 feet.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Rowena and Arlene are going to make a triangular path in her garden.
The sides will be 20 feet, 36 feet, and 18 feet.
The length of the path is given by the perimeter of the triangle. Then we have

Ali bought his mom 2 dozen (24) of roses. 1/3 of them are red and the rest are pink. How many are pink
Answer:
there are 16 pink roses
Step-by-step explanation:
Number of pink roses = fraction of pink roses x total number of roses bought
fraction of pink roses = 1 - fraction of red roses
1 - 1/3
= 3/3 - 1/3 = 2/3
Number of pink roses = 2/3 x 24 = 16

The second doughnut glazing machine can glare 78 dozen doughnuts in
2 hours
Based on this rate, what is the total number of hours it will take the second
machine tolar 135 doren doughnuts Show or explain how you got you
answer
Answer:
t = 3.46 hours, or 3 hours 28 minutes
Step-by-step explanation:
78 dozen donuts in 2 hours immediately reduces to 39 dozen/hour.
Donuts produced as a function of time: D(t), where t is the number of hours the macine runs.
Set D(t) = 135 dozen = (39 dozen/hr)t.
Solving this equation for t, we get:
t = 135/39 hours, or t = 3.46 hours, or 3 hours 28 minutes
