Which function has a constant rate of change equal to -3?
The given function with a constant rate of change that equals -3 is: 2y = -6x + 10.
What is Constant Rate of Change?The constant rate of change of a function = change in y / change in x. Given an equation of a function in slope-intercept form, y = mx + b, the constant rate of change is represented as m.
1. Constant rate of change of the function on the table using two pairs of values, (0, 2) and (1, 5) is:
(5 - 2)/(1 - 0) = 3/1
Constant rate of change = 3.
2. Constant rate of change of the function of the set of ordered pairs using two pairs of values, (4, 4) and (2, 2) is:
(4 - 2)/(4 - 2) = 2/2
Constant rate of change = 1.
3. Constant rate of change of the graphed function using two points on the line, (1, 1) and (0, 3) is:
(3 - 1)/(0 - 1) = 2/-1
Constant rate of change = -2.
4. Constant rate of change of the function 2y = -6x + 10:
Rewrite the equation in slope-intercept form
2y/2 = -6x/2 + 10/2
y = -3x + 5
Constant rate of change = -3.
Therefore, the function with a constant rate of change is: 4. 2y = -6x + 10

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

Answer:
72
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.

The figure shown is created by joining three rectangles. Enter the area of the figure, in square centimeters. Round to the nearest hundredth.
Answer:
235
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9*12.5=112.5
rec 2: (13.5-5.5)*(19.5-9-7)=28
rec 3:7*13.5=94.5
Then:
112.5+28+94.5=235
Newton’s law of cooling states that the temperature of an object changes at a rate proportional to the difference between its temperature and that of its surroundings. 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.
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

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 the value of x in the figure?
(4x + 2)
150°
Answer:
x=37
Step-by-step explanation:
By Vertical Angles Theorem (VAT), (4x+2) is equal to 150º, so then you just subtract 2 from both sides of the equation 4x+2 = 150, to make it 4x = 148, and then divide both sides by 4 to isolate x, and then you get x=37.

Answer: 70, 130
Step-by-step explanation:
In the given normal distribution with a mean of 100 and standard distribution of 15, 95% of values will fall between 70 and 130 using the Empirical rule of 95%.
Step-by-step explanation:
A normal distribution with a mean of 100 and a standard distribution of 15 is given.
We will find where 95% of data fall in the given normal distribution.
What is the Empirical rule of 95%?It states that in a normal distribution approximately 95% of observations fall within two standard deviations from the mean on both sides of the normal curve.
The mean in a normal distribution is the center of the normal curve.
The standard deviation in a normal distribution is the distance from the mean to the required point on either side.
We have,
Mean = 100
Standard deviation = 15
Applying the 95% rule we get,
On the right side of the normal curve
Mean + 2 x standard deviation = 100 + 2x 15 = 100 + 30 = 130.
On the left side of the normal curve,
Mean - 2 x standard deviation = 100 - 2x15 = 100 - 30 = 70.
Thus, we see that by using the Empirical rule of 95%, 95% values will fall between 70 and 130.

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.
