Answer:
to put in the value of any variable in this equation(for example 2 ) we will write it as
g(2) = 4(2) - 4(2)^2 + 7(2) -8
g(2) = 8 - 16 + 14 - 8
g(2) = -2

Find the circumference and the area of a circle with a diameter of 6m.
Use the value 3.14, and do not round your answers. Be sure to include the correct units in your answers.
Answer:
18.84956- using π
Or
18.84- using 3.14
Step-by-step explanation:
Multiple the diameter 6m by π or 3.14
Answer:
A = 28.26 C = 18.84
Step-by-step explanation:
1/2(d) = 1/2(6) = 3
3 is the radius/r
π is said to be in this equation as 3.14
Calculate Area:
A = 1/4πd^2
A = 1/4(π6^2)
A = 1/4(π36)
A = 1/4(113.04)
A = 28.6
Calculate Circumference:
C = 2πr
C = 2(π3)
C = 2(9.42)
C = 18.84
suppose that 14 inches of wire costs 84 cents at the same rate how much (in cents) will 7 inches of wire cost?
Answer:
Step-by-step explanation:
84 cents divided by 14 inches = 6 cents per inch
48 cents divided by 6 cents = 8 inches
8 inches of wire can be bought for 48 cents
The function f(x) is shown below.
If g(x) is the inverse of f(x), what is the value of f(g(2))?
Answer:
f(g(2)) = 2
Step-by-step explanation:
g(2)
g is the inverse function of x, which means that [tex]g(2)[/tex] is the value of x for which [tex]f(x) = 2[/tex], which is [tex]x = -3[/tex], and thus, [tex]g(2) = -3[/tex]
f(g(2))
[tex]g(2) = -3[/tex]
Thus
[tex]f(g(2)) = f(-3)[/tex]
Looking at the table, when [tex]x = -3, f(x) = 2[/tex]
Thus: [tex]f(g(2)) = 2[/tex]

Circumference of circle is 62.8 inches.
Step-by-step explanation:
Using Formula
Circumference of circle = 2 π r
Substitute the values
Circumference of circle = 2 × 3.14 × 10 inches.
multiply the numbers
Circumference of circle = 62.8 inches
Hence, the circumference of circle is 62.8 inches.
An automobile retailer calculates that its loss on the sale of Type M cars is given by L(50) = 8,000 and L'(50) = −500, where L(x) represents the loss on the sale of x Type M cars. What do these values tell you about losses?
Answer:
The loss on the sale of 50 type M cars is $8000, and the loss is decreasing at the rate of $500 per 50 type M car sold.
Step-by-step explanation:
Given
[tex]L(50) = 8000[/tex]
[tex]L'(50) = -500[/tex]
Required
Interpret
From the question, we understand that:
[tex]x \to[/tex] Number of cars
[tex]L(x) \to[/tex] Profit on x cars
Using the above as a point of reference,
[tex]L'(x) \to[/tex] Rate of loss per x cars
So, the interpretations are:
[tex]L(50) = 8000[/tex]
A loss of 8000 on 50 cars
[tex]L'(50) = -500[/tex]
The loss rate is a reduction of 500 per 50 car

What Is the measure of DEF?
Answer:
107
Step-by-step explanation:
EFD + 135 = 180
EFD = 45
DEF + 28 + 45 = 180
DEF + 73 = 180
DEF = 107
Answer:
∠ DEF = 107°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
135° is an exterior angle of the triangle , then
∠ DEF + 28° = 135° ( subtract 28° from both sides )
∠ DEF = 107°

SUPER URGENT: Complete the general form of the equation of a sinusoidal function having an amplitude of 6, a period of 2pi/3, and a phase shift to the left 1 unit.
y =
Answer:
A general sinusoidal equation is:
y = A*sin(w*x + p) + M
where:
A is the amplitude
w is the angular frequency
p is the phase shift
M is the midline.
Now, we know that:
Amplitude must be 6, so A = 6
period is 2*pi/3
Remember that the frequency is the inverse of the period, then:
f = 1/T
f = 1/(2*pi/3) = 3/(2*pi)
And the angular frequency is 2*pi times the normal frequency, then:
w = 2*pi*f = 2*pi*(3/2*pi) = 3
w = 3
Here we not have information about the midline, so M = 0.
And we know that the phase shift is one unit to the left.
Remember horizontal translations:
for a function f(x), an horizontal translation of N units is written as:
g(x) = f(x + N)
if N > 0, then the translation is to the left
if N < 0 , then the translation is to the right,
Here we know that the phase shift is to the left, so p must be positive, and we know that the shift is 1 unit to the left, then:
p = +1
Replacing these in the equation we get:
y = 6*sin(3*x + 1) + 0
y = 6*sin(3*x + 1)

What is the total surface area of the rectangular prism below in square meters? (Try drawing the net
of the prism if needed.)
5 m
4
2 m
3
m
Answer: The surface area (SA) would be 62 m.
Step-by-step explanation: The formula for surface area of a rectangular prism is SA= 2(length × width + height × length + width × height). We can substitute the length, width and height into the problem and get
SA= 2(3×5 + 2×5 + 3×2). Using the order of operations (PEMDAS) we can simplify the problem down to SA= 2(15 + 10 + 6), then add up what is in the parentheses and get SA= 2(31), and 2×31=62.
