Explain the difference in the meaning of the "+1" in each of the following equations: f(x)=2x^2+5x+1 and g(x)=2(x+5)^2+1
Answers:
The +1 in f(x) is the y intercept
The +1 in g(x) is the y coordinate of the vertex
====================================================
Explanation:
For f(x), plugging in x = 0 leads to
f(x) = 2x^2+5x+1
f(0) = 2(0)^2+5(0)+1
f(0) = 1
Showing that (0,1) is the y intercept of f(x).
The same is not true for g(x)
g(x) = 2(x+5)^2+1
g(0) = 2(0+5)^2+1
g(0) = 51
-------------------------------
The +1 for g(x) represents the y coordinate of the vertex. Recall that vertex form in general is
y = a(x-h)^2+k
with (h,k) being the vertex. This means we can quickly spot the vertex for g(x) without having to graph. The same cannot be said for f(x) as we need to complete the square to get f(x) into vertex form. Currently, f(x) is in standard form.

The Tama, Japan, monorail carries 92,700 riders
each day. If the monorail usually carries
5,150 riders per hour, how many hours does
the monorail run each day?
Answer:
The number of hours monorail run each day is 18.
Step-by-step explanation:
The total number of riders the monorail carry each day is:
N = 92700.
The number of riders the monorail carry per hour is:
n = 5150.
Compute the number of hours the monorail run each day as follows:
[tex]\text{Number of hours the monorail run each day}=\frac{N}{n}[/tex]
[tex]=\frac{92700}{5150}\\\\=18[/tex]

Find the surface area of the pyramid.
A.)311.4
B.)230.4
C.)212.6
D.)200.4
Please someone help I am struggling with this
Answer:
A. 311.4 ft²
Step-by-step explanation:
Use the formula for the surface area of a square pyramid: SA = 2bs + b², where b is the length of a side of the base and s is the slant height.
Plug in the values and solve:
SA = 2(9)(12.8) + 9²
SA = 230.4 + 81
SA = 311.4 ft²
The surface area of the pyramid is 311.4 square units
The surface area of a pyramid is given by the formula:
Surface Area = 1/2 × base area × slant height + perimeter of base × slant height
The base area of the pyramid is 9 × 9 = 81 square units.
The slant height of the pyramid is the length of a line segment that connects a vertex of the pyramid to the midpoint of a side of the base.
We can find the slant height of the pyramid using the Pythagorean Theorem.
slant [tex]h^{2}[/tex] = [tex]h^{2}[/tex] + [tex](base/2)^{2}[/tex]
slant [tex]h^{2}[/tex] = [tex]12.8^{2}[/tex] + [tex]9/2^{2}[/tex] = 230.4
slant height = 15.2
Therefore, the surface area of the pyramid is:
Surface Area = 1/2 × 81 × 15.2 + 4 × × 15.2 = 311.4 square units
So the answer is A.

[tex]\boxed{s=3}[/tex]
Answer:
Step-by-step explanation:
Because these triangles are similar, their sides exist in proportion to one another. Their angles are exactly the same. but their sides are proprtionate IF they are similar. We are told they are so setting up the proportion:
[tex]\frac{4}{2}=\frac{6}{s}[/tex] and cross multiply:
4s = 12 so
s = 3
You could also look at the fact that the height of the larger triangle is 4 and the height of the smaller is 2, so the larger is twice as big as the smaller; likewise, the smaller is half the size of the larger (that means the same thing). So if the larger side is 6, half of that is 3.

Real and Unequal
None of These
please give the answer as fast as you can
please
Answer:
Real and unequal
Step-by-step explanation:
We are tasked with finding the nature of the roots of the given quadratic equation.
The given quadratic equation is;
x^2 -5x -7
Firstly, we should know that we cannot solve this by factorization, as we will run into problems.
Now the catch is, although we cannot solve by factorization, we can solve by using the quadratic formula.
Now let’s check if our roots are imaginary or real.
For the roots to be imaginary or real, we will work with calculating the value of the expression b^2 -4ac
The value of this would tell us the nature of the roots. While a negative value would tell us the roots are imaginary, a positive value will tell us the roots are real.
So from the question, b = -5( coefficient of x) , while c = -7 and a = 1 ( coefficient of x^2)
Plugging these values into the equation, we have;
-5^2 - 4(1)(-7) = 25 + 28 = 53
This tells us the roots are real
The last issue is to know if the roots are equal or not.
The roots cannot be equal. This is because the term b^2 - 4ac would be in the root and yield a positive and a negative value which cannot give equal answers when added to (-b)
This from the quadratic formula;
x = {-b ± √(b^2-4ac)}/2a

Q.An observer 1.7m tall is 20sqrt(3)m away from a tower.The angle of elevation from the eye of observer to the top of the tower is 30 Find the height of the tower
plz Answer me
Answer:
21.7 m
Step-by-step explanation:
The question above is a right angle triangle and we would be using the trigonometric function of tangent to solve for it.
tan θ = Opposite/ Adjacent
Opposite side = Height = unknown
Adjacent = 20sqrt(3) m
θ = Angle of Elevation = 30°
Hence, we have:
tan 30° = Opposite/ 20√3
Opposite = tan 30° × 20√3m
Opposite = 20m
Height of the tower = Height of the observer + Height (Opposite side)
Height = 20m
Height of the the observer as given in the question is = 1.7m
Height of the tower = 20m + 1.7m
= 21.7m
Therefore, the height of the tower = 21.7m

The length and width of a book cover are 22.2 centimeters and 12 centimeters respectively. The actual length (and width) can be 0.3 unit less than the measured length (and width) or 0.3 unit greater than the measured length (and width). a. Find the minimum and maximum possible lengths and widths of the book cover. b. Calculate the minimum and maximum possible areas of the book cover.
Part (a)
The length is supposed to be 22.2 cm, but it could be 0.3 cm less
So 22.2 - 0.3 = 21.9 cm is the smallest value for the length. This is the lower bound of the length.
The upper bound is 22.2 + 0.3 = 22.5 cm as it is the largest the length can get.
-------------
Use this for the width as well
The width is supposed to be 12 cm, but it could be as small as 12-0.3 = 11.7 cm and as large as 12+0.3 = 12.3 cm
-------------
Answers:smallest length = 21.9 cmlargest length = 22.5 cmsmallest width = 11.7 cmlargest width = 12.3 cm============================================
Part (b)
Use the smallest length and width to get the smallest possible area
smallest area = (smallest width)*(smallest length) = 11.7*21.9 = 256.23
-------------
Repeat the same idea but for the largest length and width to get the largest possible area
largest area = (largest width)*(largest length) = 12.3*22.5 = 276.75
-------------

Answer:
Answer: D : Median, because there is 1 outlier that affects the center
Step-by-step explanation:
Mean and median terms are use to measure the central tendency in a data set.
Mean is the best measure of center if there is no outlier present in the data otherwise median is the best measure of center if there is outlier present because outliers effects the means value of a data but not the median value.
In the third period, there is an outlier present as 8 that affects the center, then the best measure of center for third period must be Median.
