Which of the following sets of numbers could not represent the three sides of a
triangle?
O {11, 22, 31}
O {8, 11, 16}
O {6,20,27}
O {11, 20, 29}
Answer:
C
Step-by-step explanation:
The third one down. There are two ways you know this.
1. If you had two boards that where 6 cm and 20 cm and tried to make a triangle with the third side = 27, the two little boards would lie flat on the 27 cm board.
2. The other three answers all make the smaller two sides larger than the third larger side.

The composite functions are listed below:
g ° f(3) = 29 g ° f(x + 1) = 2 · x² - 1 h ° g (- 3 · x) = - 36 · x - 36 f ° g (- 2 - t) = 73 + 72 · t + 16 · t² f ° g (x²) = 3 · x² + 17How to evaluate composite functions
In this problem we find five cases of composite functions, each of which has to be evaluated. A composition between the two functions f and g is defined below:
f ° g(x) = f ( g(x) )
Now we proceed to evaluate each of the five cases by using algebra properties and the definition of the composition of functions:
Case 1
g ° f(3) = g( f(3) )
g ° f(3) = 4 · (2 · 3 + 2) - 3
g ° f(3) = 4 · 8 - 3
g ° f(3) = 29
Case 2
g ° f(x + 1) = g( f(x + 1) )
g ° f(x + 1) = 2 · [(x + 1)² - 2 · (x + 1)] + 1
g ° f(x + 1) = 2 · (x² + 2 · x + 1 - 2 · x - 2) + 1
g ° f(x + 1) = 2 · (x² - 1) + 1
g ° f(x + 1) = 2 · x² - 1
Case 3
h ° g (- 3 · x) = h( g (- 3 · x) )
h ° g (- 3 · x) = 3 · [4 · (- 3 · x) - 3]
h ° g (- 3 · x) = 3 · (- 12 · x - 12)
h ° g (- 3 · x) = - 36 · x - 36
Case 4
f ° g (- 2 - t) = f( g (- 2 - t))
f ° g (- 2 - t) = [4 · (- 2 - t) - 2]² + 1 + 2 · [4 · (- 2 - t) - 2]
f ° g (- 2 - t) = (- 8 - 4 · t - 2)² + 1 + 2 · (- 8 - 4 · t - 2)
f ° g (- 2 - t) = (- 10 - 4 · t)² + 1 + 2 · (- 10 - 4 · t)
f ° g (- 2 - t) = 100 + 80 · t + 16 · t² + 1 - 20 - 8 · t
f ° g (- 2 - t) = 73 + 72 · t + 16 · t²
Case 5
f ° g (x²) = f( g(x) )
f ° g (x²) = 3 · (x² + 4) + 5
f ° g (x²) = 3 · x² + 12 + 5
f ° g (x²) = 3 · x² + 17

A satellite dish is the shape of a paraboloid. The dish is 38 inches wide, and 10 inches deep. How many inches should the receiver be located from the vertex for optimal reception? (round to the nearest thousandth)
Answer:
9 in approx
Step-by-step explanation:
Step one:
given data
the shape of the satellite dish takes the form of a paraboloid.
the diameter of the dish is 38in wide
and 10 inches deep.
step two:
The expression for the paraboloid is
[tex]4ay=x^2[/tex]
where y is the vertical axis of the paraboloid
a is vertex to focus.
and x is the radius of the dish
x= 38/2= 19in
substituting we have

in Mateo's grade, there are 100 students, Currently, 25% of them are enrolled in health, How
many students are enrolled in health?
Answer:25
Step-by-step explanation:
Answer:
25!
Step-by-step explanation:
Whenever multiplying by a percentage, you always take the whole number and multiply it by the decimal amount of the number. In this case, 25% is equivalent to 1/4 of an amount, so there would be 25 students enrolled in health. I hope this helped! <3
Find the length of RS.
a) About 6.3 units
b) 8 units
c) About 2.8 units
d) 40 units
(pls help :,) )
Answer:
i is about 23.5 so you could say c)
Step-by-step explanation:
The line segment is RST.
Since RS is 1/3 of the total length, ST is 2/3.
Therefore, 2(RS) is = ST, and RS + ST = RT.
2(3x -20) = 4x - 11
6x - 40 = 4x - 11
2x = 29
x = 14.5
3(14.5) - 20 = 23.5
4x - 11 = 47
2(23.5) = 47
The length of RS is 23.5.
The length of ST is 47.
The total length of RT is 70.5.

On a computer screen, Jennifer just created a triangular design of banner with vertices at A (-4,3) B(-1,5) and C (-1,2) she can use the computer software to perform transformations on this design. Which sequence of two transformations could she perform so that the transformed vertices become A (4,-5) , B (7,-7) and c (7,-4)
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are dilation, reflection, translation and rotation.
Given the vertices A (-4,3) B(-1,5) and C (-1,2).
If the vertices is reflected across the y = -1 line, the new location would be at:
A' (-4, -5). B'(-1, -7) and C'(-1, -4)
If it is then translated 8 units to the right i.e. (x, y) ⇒ (x + 8, y), the new location would be at:
A"(4, 5), B"(7, -7) and C"(7, -4)

1. Set up the two equations that describe this situation.
2. How many Baby Ruth bars did Michael sell?
Answer:
See below
Step-by-step explanation:
Let the number of Payday be p and Baby Ruth be b
Then sub of the candy bars:
p + b = 220Payday candy bars worth ⇒ $2pBaby Ruth candy bars worth ⇒ $3bTotal ⇒ $6001. Required equations:
p + b = 2202p + 3b = 6002. Solving by substitution:
p = 220 - b, consider it in the second equation
2(220 - b) + 3b = 600660 - 2b + 3b = 600660 + b = 600b = 660 - 600b = 6060 Baby Ruth candy bars sold
a. when u and v are nonzero vectors, span{u,v} contains only the line through u and the line through v and the origin.
Span{u, v} contains the lines through u and v. But Span{u, v} also contains u + v which does not lie on either line.
A vector basic definition What is it?
A quantity or phenomena with independent qualities for both magnitude and direction is called a vector. The term can also refer to a quantity's mathematical or geometrical representation. Velocity, momentum, force, electromagnetic fields, and weight are a few examples of vectors in nature.False, If the vectors are said to span, then they encompass the area enclosed by au + bv, where a and b are real values. The line between u + v and the origin is a straightforward counterexample. This would be referred to as a plane via u, v, and the origin since it contains all possible combinations of u and v as well as multiples of each.Learn more about vector

A town is storing salt for the winter in a cylindrical building. The building has a radius of 5 ft and is 30 ft tall. The building contains 1,500 ft3 of salt. What is the approximate height that the salt reaches in the building?
The answer are:
A. 0.5 ft
B. 5 ft
C. 19 ft
D. 22 ft
Answer:
To start off, we know the problem involves something with volume as it is 3D and has a cubic in it.
We know r = 5, h = 30, and v = 1500
The volume for a cylinder in 3d is : V=[tex]\pi[/tex][tex]r^{2}[/tex]h
We're solving for the height when the cylinder has a volume of 1500, therefor, we will solve for height.
Using our volume equation we plug in all values except h because we're solving for it.
1500=[tex]\pi r^{2} h[/tex]
1500=[tex]\pi 5^{2} h[/tex]
1500=25[tex]\pi[/tex](h)
1500/25[tex]\pi[/tex] = h
60/[tex]\pi[/tex] = h
60/[tex]\pi[/tex] = 19.0985
H is 19ft. (C)
Yohanna is conditioning all summer to prepare for her high school's varsity soccer team tryouts. She is incorporating walking planks into her daily workout plan. Every day, she will complete six more walking planks than the day before. If she starts with two walking planks on the first day, how many walking planks will Yohanna do on the 15th day?
Answer: 86
Step-by-step explanation:
Since we want to know the number of walking plans that she will do on the 15th day, we have to use 14 days in our calculations as the first day isn't included.
Therefore, the equation to solve this will be:
= 2 + 6d
where,
d = number of days = 14 days
= 2 + 6d
= 2 + 6(14)
= 2 + 84
= 86
