Answer:
h(4 - n) = -2 + 3n
Step-by-step explanation:
h(t) = 10 - 3t
plug in 4 - n for t
h(4 - n) = 10 - 3(4 - n)
distribute the 3 into the parentheses
h(4 - n) = 10 - 12 + 3n
combine like terms
h(4 - n) = -2 + 3n

Answer:
m-4 = 64 degrees.
Step-by-step explanation:
180 - 116 = 64
supplementary angles are when 2 degrees add up to 180
so if one of them is 116 then you subtract that from 180 and get 64
so the other angle would be 64 degrees
Answer:
64 degrees
Step-by-step explanation:
Supplementary angles add up to 180
180-116=64
P is between A and E, AE=27.3 and AP=12.8. What is the length of PE?
The length of line PE from the distance AE is 14.5
The schematic view showing the illustration of the question is shown in the image attached below.
Given that:
line AE = 27.3line AP = 12.8Line AP shows the distance halfway to line AE.
In order to determine the value of line PE, we need to subtract the value of line AE from PE.
i.e.
AE = 27.3 - 12.8AE = 14.5Therefore, we can conclude that the length of PE is 14.5

Any idea on how to do this? I'm a little confused.
Answer:
12
Step-by-step explanation:
You are given two lines, the blue one and the one with the letters and are told to find the length of UV (which would just be from point U to point V)
The blue line seems to represent the total length of the black line and the length of VW is already shown. Since the total length is 16 and we alredy know that VW is 4, we'll subtract the two to find the length of UV
Which would be: 16-4=12
Answer:
Answer is 12.
Step-by-step explanation:
If UW is 16, and VW is 4, then just do 16-4 to get 12.

To factor 9x^2 - 4, you can first rewrite the expression as:
A. (3x-2)^2
B. (x)^2 - (2)^2
C. (3x)^2 - (2)^2
D. None of the above
Answer:
C. (3x)^2 - (2)^2
Step-by-step explanation:
Each of the two terms is a perfect square, so the factorization is that of the difference of squares. Rewriting the expression to ...
(3x)^2 - (2)^2
highlights the squares being differenced.
__
We know the factoring of the difference of squares is ...
a^2 -b^2 = (a -b)(a +b)
so the above-suggested rewrite is useful for identifying 'a' and 'b'.

If the area of A is 8 cm^2, calculate area of B
Answer:
216.32 cm²
Step-by-step explanation:
Given that the scale factor is 5.2 then the area scale is
(5.2)² , thus
area of B = area of A × (5.2)² = 8 × (5.2)² = 216.32 cm²

Solve for s.
0.5s +1= 7+ 4.58
S =?
Answer:
s = 21.16
Step-by-step explanation:
0.5s +1= 7+ 4.58
Combine like terms
0.5s +1=11.58
Subtract 1 from each side
0.5s +1-1= 11.58-1
.5s = 10.58
Multiply by 2
.5s *2 = 10.58*2
s = 21.16
Answer: s = 21.16
Step-by-step explanation:
0.5s + 1 = 7 +4.58 Combine like terms on the right side
0.5s + 1 = 11.58 Subtract 1 from both sides
-1 -1
0.5s = 10.58 Divide both sides by 0.5
s = 21.16

Which is the best type of graph to model the speed of a roller coaster over the full two minutes it takes to complete the ride? a qualitative graph a discrete graph a bar graph a histogram
Answer:
A qualitative graph
Graphs are used to show the relationship between related quantities.
The best type of graph to model the speed over the full two minutes, is a discrete graph.
From the question, we have the following variables:
SpeedTimeThe best type of graph must show the trend between the speed of the roller coaster and the time.
Analyzing the options, we have:
Both variables are numerical data, and a qualitative graph cannot be used as a model; because qualitative graphs are used for non-numerical data.Bar graphs and histograms are used to show distributions; not trendsThe discrete graph (see attachment) is used for numerical data, and it can also be used to show trends (by connecting the dots)Using the above analysis, we can conclude that the best type of graph to use, is a discrete graph

What are some basic properties of exponentiation?If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation(the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}[/tex]
We can right it as;
0.3 x 0.3 x 0.3
= 0.09 x 0.3
= 0.027
Therefore, 0.3^3 is just 0.3 times itself 3 times. Thus, 0.027 option 2 is correct.
