Answer:
(i) The axis of symmetry is [tex]x = -4[/tex].
(ii) The axis of symmetry is [tex]x = 4[/tex].
(iii) The axis of symmetry is [tex]x = 1[/tex].
Step-by-step explanation:
We proceed to explain how we determine the expression for the axis of symmetry for each case:
(i) [tex]f(x) = 3\cdot (x+4)^{2}+1[/tex]
The expression depicts a vertical parabola, meaning that axis of symmetry is vertical, that is, a function of the form [tex]x = a,\,\forall\,a\in \mathbb{R}[/tex]. This line passes through the vertex of the parabola. The component [tex]x+4[/tex] contains the information of the horizontal component of the vertex, where the axis passes through. Therefore, the axis of symmetry is [tex]x = -4[/tex].
(ii) [tex]f(x) = 2\cdot x^{2} -16\cdot x +15[/tex]
At first we complete the square and factor the perfect square trinomial:
[tex]f(x) = 2\cdot \left(x^{2}-8\cdot x +\frac{15}{2} \right)[/tex]
[tex]f(x) = 2\cdot \left[(x^{2}-8\cdot x +16) +\frac{15}{2}-16 \right][/tex]
[tex]f(x) = 2\cdot (x-4)^{2}-17[/tex]
By applying the approach used in (i), we find that the axis of symmetry is [tex]x = 4[/tex].
(iii) First, we locate the vertex of the parabola, which is (1,-3). The first component of the ordered pair contains all the needed information to determine the equation of the axis of symmetry, which is [tex]x = 1[/tex].

A map has a scale of 1/2 inch =75 miles.If two cities are 3 3/4 inches apart,how many miles apart are they really
Answer:
3 3/4 inches = 562.5 miles
Step-by-step explanation:
Given that,
1/2 inch = 75 miles
It means,
1 inch = (75×2) miles
= 150 miles
3 3/4 inches= 15/4 inches
So,
[tex]\dfrac{15}{4}\ \text{inches}=\dfrac{15}{4}\times 150\\\\=562.5\ \text{miles}[/tex]
Hence, 3 3/4 inches is equal to 562.5 miles.

If one tenement on the Lower East Side of New York had 101 adults and 91 children, and there was an average of 8 persons in a tenement apartment, how many apartments did this tenement have?
Answer:
24 Apartments
Step-by-step explanation:
To get the total amount of people living in the apartment building, you add 101 and 92.
101+91=192 total people
You then divide this total by the amount of people staying in each apartment, which is 8.
192/8=24 apartments
This leaves you with 24 apartments, with 8 people living in each one.

help please! factoring polynomials
Answer:
B
Step-by-step explanation:
you can use foil and the graph,
because you can see (in the graph) that the lines intersect at 1 and 4.
just use foil to help figure out which matches the slope.
something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be
-2 and -2, 2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.

If Brooke and her friend can bake 24 batches of brownies in 8 hours, and they both work 40 hours in one week, how many batches of brownies can they bake that week? If Brooke still charges $2.00 a batch, how much money will they make that week?
Answer:
Step-by-step explanation:
40hr(24b/8hr)=120b so they make 120 batches
120b($2/b)=$240 so they make $240 together (or $120 each)

In triangle XYZ right angled at Y. Find the length of the hypotenuse if the length of the other two sides is 1.6 cm and 6.3 cm.
Answer:
6.5 cm
Step-by-step explanation:
From Pythagoras theorem
C^2= a^2 + b^2
Where a, b are the sides of the triangle
C= hypotenus sides of the triangle
two sides are given as 1.6 cm and 6.3cm respectively.
C^2= 1.6^2 + 6.3^2
C^2= 2.56 + 39.69
C^2 = 42.25
C= √42.25
C=6.5 cm
Hence, the length of the hypotenuse is 6.5 cm

2003 3042
2004 | 3087
2005 3136
2006 3296
The equation for the line of best fit shows the relationship between the number of students enrolled
The equation for the line of best fit, then predict the number of students enrolled in 2011 is [tex]y = 90.2x - 177670.2[/tex]
How to determine the equation of the line of best fitTo do this, we make use of a graphing calculator that has the following calculation summary
Sum of X = 10020Sum of Y = 15453Mean X = 2004Mean Y = 3090.6Sum of squares (SSX) = 10Sum of products (SP) = 902b = 90.2a = -177670.2A regression equation is represented as:
[tex]y = bx + a[/tex]
So, we have:
[tex]y = 90.2x - 177670.2[/tex]
Hence, the regression equation is [tex]y = 90.2x - 177670.2[/tex]

A bakery sold a total of 200 cupcakes in a day, and 86% of them were mocha flavored. How many of the cupcakes sold that day were mocha flavored?
Answer:
172
Step-by-step explanation:
200 x 0.86 = 172
172 cupcakes sold were of mocha flavoured.
What is Percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a bakery sold a total of 200 cupcakes in a day, and 86% of them were mocha flavoured.
Let the number of mocha cupcakes sold are x,
Therefore, 86% of 200 = x
x = 200*86/100
x = 2*86
x = 172
Hence, the number of mocha cupcakes sold were 172.
