F(x) = 3 x 2 − 3 x − 6 The domain of a the function f(x) is { -10, -1, 1, 5 }. What is the range of the relation?
Answer:
{324, 0, -6, 54}
Step-by-step explanation:
Given that F(x) = 3x² − 3 x − 6 If the domain of a the function f(x) is { -10, -1, 1, 5 }.
To get the range, we will find f(x) for all the domains
at x = -10
f(-10) = 3(-10)²-3(-10) - 6
f(-10) = 3(100)-3(-10) - 6
f(-10) = 300+30-6
f(-10) = 330-6
f(-10) = 324
at x = -1
f(-1) = 3(-1)²-3(-1) - 6
f(-1) = 3(1)-3(-1) - 6
f(-1) = 3+3-6
f(-1) = 6-6
f(-1) = 0
at x = 1
f(1) = 3(1)²-3(1) - 6
f(1) = 3(1)-3(1) - 6
f(1) = 3-3-6
f(1) = 0-6
f(1) = -6
at x = 5
f(5) = 3(5)²-3(5) - 6
f(5) = 3(25)-3(5) - 6
f(5) = 75-15-6
f(5) = 60-6
f(5) = 54
Hence the range of the relation are {324, 0, -6, 54}

What is most often given a value of zero to describe an object’s position on a straight line?
displacement
reference point
distance
ending location
Answer:
Reference Point
Step-by-step explanation:
The answer is reference point. This is because reference point is used to determine if an object is in motion or if it has changed is direction.
Thus, reference point has to be a value of zero for us to use it to determine if an object has moved.
Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid). The building has a 64×64 m end text square base and is 36 m tall. The cut off section has an a16×16m square base and is 12 m tall. What is the volume of the building? Round to the nearest cubic meter.
Answer:
64,512 m3
Step-by-step explanation:
3 1
(base area)(height) = 3 1
(64⋅64)(48) =65,536
The volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.
What is a right square pyramid?In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the squares joints at the top which is perpendicular to the center of the square.
We know volume for the right square pyramid is given by:
[tex]\rm V= \frac{1}{3} b\times h[/tex]
Volume for the cut off portion:
[tex]\rm v = \dfrac{1}{3}\times16\times16\times12[/tex]
v = 1024 cubic meters
Volume for the completer pyramid"
[tex]\rm V=\dfrac{1}{3}\times64\times64\times48[/tex]
V = 65536 cubic meters
Volume of the building = 65536 - 1024
= 64512 cubic meters
Thus, the volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.

Step-by-step explanation:
6.9+5+4.1
11+5
16
pls thanks
Answer:
16
Step-by-step explanation:
Recall that the product of a negative number and another negative number is a positive number. Thus, -(-5) = +5, and the original expression becomes
6.9 + 5 + 4.1.
Combining the mixed numbers 6.9 and 4.1, we get 11.
Combining 11 and 5 results in 16.

Identify the initial amount a and the rate of decay r (as a percent) of the exponential function y = 8(1 – 0.15). Evaluate the function
when t = 3. Round your answer to the nearest tenth.
Answer:
Initial amount = 8
Decay rate = 15%
Step-by-step explanation:
Given the exponential function :
y = 8(1 – 0.15)
The general form of an exponential Decay function is :
A = P(1 - r)^t
Where
A = final amout ; P = initial amount ; r = days cay rate ; t = time
Hence, comparing with the equation given :
P = 8 = initial amount
r = 0.15 = 0.15 * 100% = 15% = Decay rate

If 0 < z ≤ 90 and sin(9z − 1) = cos(6z + 1), What is the value of z?
Answer:
6Step-by-step explanation:
Given the expression sin(9z − 1) = cos(6z + 1), for 0 < z ≤ 90, we are to find z
Note that sin theta = cos(90-thetsa)
sin(9z − 1) = cos(6z + 1)
cos (90 - (9z-1)) = cos(6z + 1)
cos (90 - 9z+1)) = cos(6z + 1)
cos (91-9z) = cos(6z + 1)
Cos will cancel out to have;
91-9z = 6z+1
-9z - 6z = 1-91
-15z = -90
z = 90/15
z = 6
Hence the value of z is 6

The graph of a function is shown on the coordinate plane below. Identify the rate of change of the function.
Answer:
5/4
Step-by-step explanation:
Rise over run you go up 5 and left 4 so 5/4 is the ROC.
The rate of change of the function is given by the slope of the line m = -4/3
What is an Equation of a line?The equation of a line is y = mx + b where m is the slope which is the rise by run and b is the y-intercept
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
Given data ,
Let the rate of change of the function be m
The equation is represented as A
Now , the value of A is
Let the first point be P ( 0 , 4 )
Let the second point be Q ( 3 , 0 )
Slope m = -4/3
On simplifying the equation , we get
Slope m = -4/3
Now , the equation of line is
y - 4 = ( -4/3 ) ( x - 0 )
On simplifying the equation , we egt
y - 4 = ( -4/3 )x
y = ( -4/3 )x + 4
Hence , the equation of line is y = ( -4/3 )x + 4 and the rate of change of the function is m = -4/3
