The price for which the designer will sell the maximum number of shirts is given as follows:
$11.
How to obtain the price?As the amount sold is modeled by a concave down quadratic function, the price for which the designer will sell the maximum number of shirts is given by the x-coordinate of the vertex of the quadratic function.
The function in the context of this problem is given as follows:
S(x) = -4x² + 88x - 160.
The coefficients are given as follows:
a = -4, b = 88, c = -160.
Hence the x-coordinate of the vertex is obtained applying it's formula as follows:
x = -b/2a
x = -88/-8
x = 11. -> price of $11.

Graph the circle (x - 3)^2 + (y + 3)^2= 36.
The circle on a graph by drawing the center point and then drawing a circle around it with a radius of 6.
To graph the circle with the equation (x - 3)² + (y + 3)² = 36, we can start by finding the center and radius of the circle.
The equation of a circle in standard form is (x - h)² + (y - k)² = r² (h, k) represents the center of the circle and r represents the radius.
Comparing the given equation with the standard form, we can see that the center of the circle is (3, -3) and the radius is √36 = 6.
Using this information, we can proceed to plot the circle on a graph:
Plot the center point: (3, -3).
From the center point, move 6 units in each direction (up, down, left, and right) to determine the points on the circle.
Up: (3, -3 + 6) = (3, 3)
Down: (3, -3 - 6) = (3, -9)
Left: (3 - 6, -3) = (-3, -3)
Right: (3 + 6, -3) = (9, -3)
Connect the plotted points to form a circle.
The resulting graph should look like this:

d) Shiva bought a second-hand motorcycle for Rs 1,53,200. He spent Rs 1,200 to repair it and sold it to Bishnu at 8% loss. How much did Bishnu pay for it?
Bishnu selling price paid Rs 1,42,048 for the motorcycle.
To find out how much Bishnu paid for the motorcycle, we need to calculate the selling price after the 8% loss.
Let's start with the purchase price: Shiva bought the second-hand motorcycle for Rs 1,53,200.
Then, Shiva spent Rs 1,200 to repair it. So, the total cost for Shiva becomes:
Total cost = Purchase price + Repair cost
= Rs 1,53,200 + Rs 1,200
= Rs 1,54,400
Now, to calculate the selling price after an 8% loss, we need to subtract 8% of the total cost from the total cost:
Loss = 8% of Total cost
= 8/100 * Rs 1,54,400
= Rs 12,352
Selling price = Total cost - Loss
= Rs 1,54,400 - Rs 12,352
= Rs 1,42,048
Therefore, Bishnu selling price paid Rs 1,42,048 for the motorcycle.

2/5 of the frogs in that portion of the South American rainforest are not poisonous.
How to calculate the fraction of frogs that are not poisonous in South American rainforestOn the off chance that 3/5 of the frogs in a rainforest in South America are poisonous, at that point, the remaining division speaks to the frogs that are not poisonous.
To discover this division, we subtract the division of poisonous frogs from 1 (which speaks to the complete):
1 - 3/5 = 5/5 - 3/5 = 2/5
Hence, 2/5 of the frogs in that portion of the rainforest are not poisonous. This fraction represents the parcel of frogs that don't have poisonous characteristics.

A 1/6n √2.
B √1/9
C 1/6 √2n
Please explain the answer my radical calculator doesn't work on anything with letters in it.
Answer: C 1/6*√2n
Step-by-step explanation:
• Simplify √n/18 as (1/3)^2*n/2
• Multiply them under the radical so the squares 1/3 cancels out to 1/3*√n/2
• Multiply the √n/2 on both sides as √2*n/√2*√2 so it comes out to √2n/2
• Multiply √2n/2 with 1/3 to make √2n/6
√2n/6 is equal to 1/6*√2n
The radical expression √n/18 when simplified is 1/3√n/2
Simplifying the radical expressionFrom the question, we have the following parameters that can be used in our computation:
√n/18
Express 18 as 9 * 2
So, we have the following representation
√n/18 = √n/(9 * 2)
Rewrite as

Take the square root of 9

A baseball player earns $3 million in 2015. During the next 15 years, the earning increase 4% each year.
Write an exponential growth model giving the earning y (in millions of dollars) t years after 2015. Write the base of the model as a decimal
The exponential growth model for the baseball player's earnings, in millions of dollars, t years after 2015 is[tex]y = 3 \times (1.04)^t,[/tex] with a base of 1.04.
To model the exponential growth of the baseball player's earnings, we can use the formula:
[tex]y = a \times (1 + r)^t[/tex]
where:
y represents the earning in millions of dollars
a represents the initial earning in millions of dollars (in this case, $3 million)
r represents the growth rate per year (4%, which can be expressed as 0.04)
t represents the number of years after 2015
In this case, we want to find the earning y (in millions of dollars) t years after 2015.
Since the initial earning in 2015 is $3 million, we can substitute a = 3.
Therefore, the exponential growth model for the player's earnings is:
[tex]y = 3 \times (1 + 0.04)^t[/tex]
Simplifying the expression further, we have:
[tex]y = 3 \times 1.04^t[/tex]
The base of the model is 1.04, which is the decimal representation of the growth rate (4%).
Using this model, we can calculate the player's earnings for any year after 2015 by plugging in the value of t.
For example, if we want to find the earnings 5 years after 2015, we substitute t = 5 into the equation:
[tex]y = 3 \times 1.04^5[/tex]
This will give us the projected earnings in millions of dollars for that particular year.

Select all the ways that describe rigid transformations that take AEFD to CFEB.
The rigid transformations that can take AEFD to CFEB are translation, rotation, and reflection.
To describe the rigid transformations that take polygon AEFD to CFEB, we need to identify the transformations that preserve the shape and size of the polygon. Here are some possibilities:
Translation: A translation involves moving the entire polygon without changing its orientation or shape. If we shift polygon AEFD to the right, it will align with polygon CFEB. Therefore, translation is one way to achieve this transformation.
Rotation: If we rotate polygon AEFD around a fixed point, such as the center of the polygon or a vertex, by a certain angle, it can align with polygon CFEB. A rotation preserves the shape and size of the polygon.
Reflection: A reflection involves flipping the polygon across a line, resulting in a mirror image. If we reflect polygon AEFD across a line of reflection, it can match polygon CFEB.

6 hours
Step-by-step explanation:
Varying inversely simply means using the "inverse proportion" methodSo therefore,
4 roofers= 1 hour
1 roofer= 9 * 4
= 36 hours
Why? Because the lesser amount of workers you have, the more time will be needed so as to complete the work.6 roofers= 36/6=6 hours

The direction that the quadratic function f(x) is to be translated is to the left and the units is 4.
Here given two functions, f(x) and g(x).
General form of the quadratic function is,

It is clear that, f(x) is simply the square of the x values.
f(x) = x²
Since g(x) is the translation of the function f(x) and the value of g(x) = 0, when x = -4,
g(x) = (x + 4)²

We have to given that,
A bag has 6 blocks in it. Jerry picks a block out of the bag 60 times. He gets the green block 43 times.
Since, We know that Jerry picked a block out of the bag 60 times, and got the green block 43 times.
So the probability of picking a green block is:
P = 43/60
P = 0.7167
This means that out of every 60 blocks picked, there are 43 green.
Now, For this probability to estimate the number of green blocks in the bag.
since, Jerry picked 60 blocks 6 times
When, we assume that the bag contains a total of 360 blocks , we can multiply this total by the probability of getting a green block:

How to find the angles in a cyclic quadrilateral?A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. The sum of angles in a cyclic quadrilateral is 360 degrees.
Opposite angles of a cyclic quadrilateral is supplementary.
c = 180 - 96
c = 84 degrees
d = 180 - 100
d = 80 degrees
100 = 1 / 2 (a + 99)
100 = 0.5a + 49.5
0.5a = 50.5
divide both sides by 0.5
a = 50.5 / 0.5
a = 101 degrees
84 = 1 / 2 (101 + b)
