on a piece of paper graph y=(x+2)(x-3) then determine which answer choice best matches the graph you drew. Provide an explanation comments for links will be reported.
Answers
Answer:
option C
Step-by-step explanation:
Given :-
y = (x + 2)( x -3)And we need to tell which graph best matches the graph we drew. Firstly let's convert it into a quadratic equation by opening and simplifying the brackets.
[tex]:\implies[/tex] y = ( x + 2) ( x - 3)
[tex]:\implies[/tex] y = x ( x - 3)+2( x - 3)
[tex]:\implies[/tex] y = x² - 3x + 2x -6
[tex]:\implies[/tex] y = x² - x - 6
Now plot its graph. For that refer to attachment.
Things we can interpret :-
The constant in the equation is -6. So the graph will cut y axis 6 units below the X axis . At (-6,0) From the given options , option C matches the above point .Therefore the correct option is (C) .

Suppose that the temperature of a cup of coffee obeys Newton’s law of cooling. If the coffee has a temperature of 200◦F when freshly poured, and 1 min later has cooled to 190◦F in a room at 70◦F, determine when the coffee reaches a temperature of 150◦F.
Answers
Answer:
6 mins
Step-by-step explanation:
Given that;
T(t) = Ce^-kt + T(s)
Since T(t) = 200◦F, and T(s) = 70◦F where t = 0
200= Ce^-k(0) + 70
C= 200 - 70
C = 130
Then when T(t) = 190◦F and t= 1s ;
190 = 130e^-(k *1) + 70
190 - 70 = 130e-^(k *1)
120/130 = e^k
0.923 = e^-k
-k = ln(0.923)
k = 0.08
To determine the time taken to reach a temperature of 150◦F
150 = 130e^-(0.08t) + 70
150 - 70/130 = e^-(0.08t)
0.6154 = e^-(0.08t)
-(0.08t) = ln 0.6154
0.08t = 0.4855
t = 0.4855/0.08
t = 6 mins

In a room, there are four chairs. The first chair is towards North, the third chair is towards south, the second chair is towards east and fourth chair is towards west. If the distance between any two consecutive chairs is equal and all the interior angles are 90° each, then which of the following shape is formed?
A) Square
B) Rectangle
C) Trapezium
D) Circle
Answers
Answer:
The correct answer is A. The shape formed by the four chairs is a square.
Step-by-step explanation:
A square is a figure whose 4 sides are exactly equal in length, and whose 4 interior angles are equal to 90 degrees each. Thus, if the distance between the chairs is exactly the same between them, it is understood that the "sides" of the figure are all the same. Thus, if all the internal angles of the figure are 90º, the figure that the chairs form is a square.

Answers
Answer:
A
Step-by-step explanation:
As the price goes up per dollar there is a definite decrease in sales. Specifically, about 5 shirts don't get sold per increase of one dollar.
The correct option is A. for every one dollar price increase of T- shirt, 5 fewer T-shirts were sold.
What is a scatter plot?A scatter plot is a type of data visualization that shows the relationship between different variables. This data is shown by placing various data points between an x- and y-axis. Essentially, each of these data points looks “scattered” around the graph,
Given equation of line for that fits best for scattered data is y -5x + 80
From the graph it is clear that as the slope of the given equation is decreasing one
y -5x + 80 =0
y ∝ -mx
(no. of T-shirts sold) ∝ (-5) × (price of a T-shirt)
So, as the price of the T-shirt increases the less T-shirt were sold.

Step-by-step explanation:
Volume of a triangular prism = L x B x H x 1 / 2
So in this case itd be
V = 2 x 9 x 8 x 1/2
V = 72 x 1/2
V = 36
Now it wants BOTH prisms and their congruent so
36 x 2 = 72
Answer:
The answer is C.
Explanation:
C is the answer because volume you multiply length times width times height. 9 times 2 time 8 = 144. When you use volume, it is always going to be to the 3rd power or cubed. Any way you say it.

Answer:
W(x) = 27/256(x)(32-x)
Step-by-step explanation:
There are several ways you can do this. The method we've used here is to write a function that has zeros at x=0 and x=32, opens downward, and has a maximum at x=16 of 27.
The zeros give rise to the factored form ...
w = x(x -32)
To make it open downward, we need to reflect this across the x-axis. We can add a leading minus sign, or we can swap the terms in the binomial that has a minus sign:
w = -x(x -32) = x(32 -x)
This will have a value of 16(32 -16) = 256 at its peak. We want the peak to be 27, so we can vertically scale this function by a factor of 27/256. The grap attached shows this gives the desired result.
W(x) = (27/256)(x)(32-x)

What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
