Write one function for each house to describe the value of the house f(x), in dollars, after x years.
straightAnswer:
Step-by-step explanation:
The strategy would be to look for the equations of lines that passes for the points. it can be done but it's a hard work. I prefer to use a calc sheet . You can se that house 2 has a perfect fit to data because it has a [tex]R^2=1[/tex], however house 1 does not have a perfect fit, [tex]r^2=0.99..[/tex] altough it is a very good fit, in the image you can see the corresponding equations

find the domain and range in each of the following
Step-by-step explanation:
Domain: possible value of x
Range: possible values of y
Domain:
Given in the question
-1smaller or equal to x smaller or equal to 1
Range:
y is greater than 1, smaller than 3
[tex] \sqrt{ \frac{y - 1}{2} } = x \\ [/tex]
y cannot be smaller than 1
when substitute velue of x= 1 or negative 1
we get y=3 and any values between 1 and negative 1 when substitute in x, will give values of y in between 3 and 1.
first list all elements of x and y..
x= -1,0,1
y=2x^2+1
whenx=-1 y=2×-1^2+1=5
similarly, when x=0,y=1
x=1, y=5
therefore, domain=x={-1,0,1}
range=y={1,5}
Natalie just rented an apartment for $900 a month.she was told that the rent will increase 5.5% each year. About how much will her rent be in 7 years
Answer:
Step-by-step explanation:
the equation you write to solve this should be:
x = 900 (1 + 0.055)^7
x = 900 (1.055)^7
x = 900 (1.454679131133794609375)
x = 1,309.21

Answer:
(f o g)(x) = 4x^4 - 24x^2 + 37
(g o f)(x) = 16x^4 + 8x^2 - 2
Step-by-step explanation:
f(x) = 4x^2 + 1
g(x) = x^2 - 3
(f o g)(x) = f(g(x)) = f(x^2 - 3) = 4(x^2 - 3)^2 + 1 =
= 4(x^4 - 6x^2 + 9) + 1
= 4x^4 - 24x^2 + 37
(g o f)(x) = g(f(x)) = g(4x^2 + 1) = (4x^2 + 1)^2 - 3 =
= 16x^4 + 8x^2 - 2

Answer:
x could be 0 or it could be 5/2
Step-by-step explanation:
Answer:
x= 5/2
Step-by-step explanation:
4x^2 + 4x - 14x = 0
subtract 4x from 14x because they are like terms
4x^2 - 10x=0
4x^2 = 0 + 10x
4x^2 = 10x
x^2/x = 10/4

Suppose that y varies directly with x and inversely with z; y = 27 when
x = 21, and z = 7. Write the equation that models the relationship. Then
find y when x = 25 and z = = 5.
The value of y is 45 when x = 25, z = 5 and the value of constant of proportionality is 9, and equation is y = 9x/z
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
We have:
y varies directly with x and inversely with z.
y ∝ x/z
Removing the proportional sign.
y = kx/z
k is the constant of proportionality.
Plug y = 27, x = 21, and z = 7 to get the value of k
27 = 21k/7
k = 9
y = 9x/z
Plug x = 25, and z = 5
y = 9(25)/5
y = 45
Thus, the value of y is 45 when x = 25, z = 5 and the value of constant of proportionality is 9, and equation is y = 9x/z

write the equation of a circle with a center at (-1, -4) that passes through the point (-1,-1)
Answer:
Equation of the circle :
[tex](x+ 1)^2 + (y+4)^2 = 9[/tex]
Step-by-step explanation:
Equation of a circle with centre (a, b) and radius ,r :
[tex](x - a)^2 + (y-b)^2 = r^2[/tex] ------(1)
Here a = -1, b = -4
find radius:
Since the circle passes through (-1, -1) , the radius is the distance between the centre and the point.
[tex]distance, r = \sqrt{(-1 -(-1))^2 +(-4 -(-1))^2 }[/tex]
[tex]= \sqrt{9} = 3[/tex]

Answer:
The x-coordinates for which the gradient of the curve is 5 is at x = -1/2 and x = 1/2.
Step-by-step explanation:
We have the function:
[tex]\displaystyle y=\frac{x^2 -1}{x}[/tex]
And we want to find the x-coordinates for which the gradient (or slope) at the point is 5.
The gradients of a curve at a point is given by its derivative. Find the derivative:
[tex]\displaystyle \frac{dy}{dx}=\frac{d}{dx}\left[\frac{x^2-1}{x}\right][/tex]
Use the quotient rule:
[tex]\displaystyle \frac{dy}{dx}=\frac{(x^2-1)'(x)-(x^2-1)(x)'}{(x)^2}[/tex]
Simplify:
[tex]\displaystyle \frac{dy}{dx}=\frac{(2x)(x)-(x^2-1)(1)}{x^2}[/tex]
Simplify:
[tex]\displaystyle \frac{dy}{dx}=\frac{x^2+1}{x^2}[/tex]
Since the gradient is 5, substitute 5 for dy/dx and solve for x:
[tex]\displaystyle 5=\frac{x^2+1}{x^2}[/tex]Multiply both sides by x² (x ≠ 0):
[tex]5x^2=x^2+1[/tex]
Subtract x² from boths sides:
[tex]4x^2=1[/tex]
Solve for x:
[tex]\displaystyle x=\pm\sqrt{\frac{1}{4}}=\frac{1}{2}\text{ or } -\frac{1}{2}[/tex]
So, the x-coordinates for which the gradient of the curve is 5 is at x = -1/2 and x = 1/2.

The ideal width of a safety belt strap for a certain automobile is4 cm. An actual width can vary by at most 0.3
cm. Write an absolute value inequality for the range of acceptable widths, in centimeters.
IW - 41 303
0214
Answer:
|x - 4| ≤ 0.3
Step-by-step explanation:
The actual width = 4
Maximum variation, x = 0.3
Hence, the lowest width position based on actual width and possible variation is :
4 - 0.3 ≤ x ≤ 4 + 0.3
3.7 ≤ x ≤ 4.3
A man is walking down a very long flight of
steps in a stairwell. He begins at 136 feet
above ground level. He walks down with a
steady rate such that he gets closer to the
ground floor at a rate of 2.8 feet per second.
The man is going to exit the stairwell at the
4th floor, which is the height of 42 feet above
ground level. Let t be equal to the number of
seconds it takes for him to get to the 4th floor.
Set up and solve the equation to find the value
of t. Round your answer to the nearest tenth
of a second.
Answer:
33.6 seconds
Step-by-step explanation:
if he begins at 136 feet and wants to go to 42 feet, the distance is 94 feet
d = 94
r = 2.8
d = rt; solving this formula for 't':
t = d/r
t = 94/2.8
t = 33.6 seconds

Answer:
no
Step-by-step explanation:
The first step is to understand that the question is asking about the future value of series of payments. An appropriate formula is ...
P = A(n/r)((1 +r/n)^(nt) -1)
where P is the future value, A is the periodic payment made n times per year for t years. r is the annual interest rate.
The next step is to substitute the given values and do the arithmetic. Using the given values, we have ...
P = 250(12/0.056)((1 +0.056/12)^(12×2.5) -1) ≈ 8030.32

what is the equation that matches this table?
Answer:
y = –1 + 3x
Step-by-step explanation:
To know which option is correct, we shall use the equation given in each option to see which will validate the table. This is illustrated below:
Option 1
y = –1x + 3
x = –2
y = –1(–2) + 3
y = 2 + 3
y = 5
This did not give the required value of y (i.e –7) in the table.
Option 2
y = 1 + 3x
x = –2
y = 1 + 3(–2)
y = 1 – 6
y = –5
This did not give the required value of y (i.e –7) in the table.
Option 3
y = –3 + 1x
x = –2
y = –3 + 1(–2)
y = –3 – 2
y = –5
This did not give the required value of y (i.e –7) in the table.
Option 4
y = –1 + 3x
x = –2
y = –1 + 3(–2)
y = –1 – 6
y = –7
This gives the required value of y (i.e –7) in the table.
Thus, the equation that matches the table is:
y = –1 + 3x
