In the first week of August, there were 1,060 people at an amusement

Marrrta [24]

Answer:

In second week there is percentage decrease (-ve sign) of 20% in people visiting compare to first week.

In third week there is percentage increase of 50% in people visiting compare to second week.

In fourth week there is percentage decrease of 75% in people visiting compare to third week.

Solution:

Need to determine percentage change in the number of people who went to amusement park for each week in august.

Given that,

In first week of august number of people went to amusement park let say $p_1$ = 1060

In second week of august number of people went to amusement park let say $p_2$ = 848

In third week of august number of people went to amusement park let say $p_3$ = 1272

And in fourth week of august number of people went to amusement park let say $p_4$ = 318

Percentage change from first week to second week is as follows

$\% \text { change }=\frac{p_{2}-p_{1}}{p_{1}} \times 100=\frac{848-1060}{1060} \times 100$

$=\frac{-212}{1060} \times 100=-20 \%$

So in second week there is percentage decrease (-ve sigh) of 20% in people visiting compare to first week.

Percentage change from second week to third week is as follows

$\begin{aligned} \% \text { change }=\frac{p_{3}-p_{2}}{p_{2}} \times 100 &=\frac{1272-848}{848} \times 100 =\frac{424}{848} \times 100=50 \% \end{aligned}$

So in third week there is percentage increase of 50% in people visiting compare to second week

Percentage change from third week to fourth week is as follows

$\begin{aligned} \% \text { change }=& \frac{p_{4}-p_{3}}{p_{3}} \times 100=\frac{318-1272}{1272} \times 100 =\frac{-954}{1272} \times 100=-75 \% \end{aligned}$

So in fourth week there is percentage decrease of 75% in people visiting compare to third week

Matty jogs 1km in 5 minutes. Identify the correct conversion factor setup required to compute Matty's speed in m/s.

alex41 [277]

1 km / 5 mins

Convert 1 km to meters:
1000 m / 5 mins

Divide by 5 on both sides:
200m / 1 min

Convert 1 min to seconds:
200m / 60 sec

Divide by 60 on both sides
3.33m / sec (nearest hundredth)

Answer: Matty's speed is 3.33m/s

Red Bookstore wants to ship books from its warehouses in Brooklyn and Queens to its stores, one on Long Island and one in Manhat

frozen [14]

Answer:

Brooklyn to Long Island = 0 books

Brooklyn to Manhattan = 1000 books

Queens to Long Island books = 1500 books

Queens to Manhattan books = 500 books

YES

Step-by-step explanation:

This is a equation's system with 4 unknown variables ( the number of the 4 kinds of shippings performed) , lets call the 4 variables like this:

a: Brooklyn to Long Island books
b: Brooklyn to Manhattan books
c: Queens to Long Island books
d: Queens to Manhattan books

Now, let´s see what we know:

1) First we know that each bookstore has asked for 1500 books so:

1500= b+d => b= 1500-d (1)

1500= a+c=> a= 1500-c (2)

2) We also know that the total amount spent in transportation is 9000$ at the given individual trasportattion prices

9000$= 5$*a+1$*b+4$*c+2$*d

=> 9000= 5a+b+4c+2d

=> c= (9000-5a-b-2d)/4 (3)

3) Finally, we know that the since we have a total number of books in the two warehouses of 3000 books, the same quantity that is demanded by the two bookstores, all the books are delivered.

So , in Brooklyn there are 1000 books that can be delivered to LI or Manhattan:

1000 = a+b => a= 1000-b (4)

and in Queens there are 2000 books:

2000 = c+d => d= 2000-c (5)

Now, formulas (2) and (4) are equal to a, so they are equal to each other

1000-b= 1500-c => b= c-500 (6)

Now lets solve by substitution in formula (3):

c= (9000-5a-b-2d)/4

=> 4c= 9000-5a-b-2d

=> 4c= 9000-5( 1500-c)- (c-500)-2*(2000-c)

=> 4c= -3000+6c => c=1500

Then:

d= 2000-c= 2000-1500=> d=500.
b= c-500 => b= 1000
a= 1500-c => c= 0

b) If we look at the trsnportation prices the cheaper is from Brooklyn to Manhattan, so lets try to maximize this tranportation.

In Brooklyn we have 1000 books, and we need 1500 in Manhattan, so lets do all the the shipping from brooklyn to Manhattan.:

1000 books *1 $/ book= 1000$

We will need 500 additional books from Queens at 2$/ book:

500 books * 2 $/book = 1000$

Then the 1500 books left in Queens will be shipped to Long Island at a price of 4$/ book:

1500 books * 4 $/book= 6000$

Total amount spent = 1000$+1000$+6000$ = 8000$

Find the vertex and axis of symmetry for f(x)=2x^2-1

vfiekz [6]

<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>

Solution:

Given is:

$f(x) = 2x^2 - 1$

We have to find the vertex and axis of symmetry

The general equation is given as:

$f(x) = ax^2 + bx + c$

Comparing with given equation,

a = 2

b = 0

c = -1

The axis of symmetry is given as:

$x = \frac{-b}{2a}$

$x = \frac{0}{2(2)}\\\\x = 0$

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

$f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1$

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)
