A squar has an area of 64cm2 find the perimeter of the square
Answer: 32 cm
Step-by-step explanation:
Answer:
All of the sides of the square are 8 cm. So the prementer would be 32 cms
Step-by-step explanation:
To find the sides of the square, you got to think what x what = 64. This shows you that 8 x 8 is 64. and since it is a square, all of the sides are the same. So 8+8+8+8 = 32 or you can do 8 x 4 = 32

Function c is defined by the equation c(n)=50+4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n. What is the inverse function.
Answer:
(x - 50 / 4) = y
Step-by-step explanation:
On photo
To find the inverse function, you will have to write n in terms of c (which means number of visits as function of monthly cost).
The inverse function would be:
[tex]n = \dfrac{c-50}{4}[/tex]
Given that:c(n) = 50 + 4nc is monthly cost in dollars, of visiting a gym.n is the number of visits.To find:Inverse function of given function.
What is inverse function and when is it possible to find such function?The inverse function of f is a function of f which can remove the effect of f on its input.
Inverse is only possible if the function f is bijective (one to one correspondence, which means one input to one output uniquely and one output is connected to only one input by mapping f)
Since the given function is a linear function and not a vertical line, thus, one input n uniquely maps to one output cost and one cost uniquely is obtained by one and only one value of n.
Finding the inverse function of c(n) = 50 + 4n:[tex]cost = 50 + 4n\\ 4n = cost - 50\\\\ n = \dfrac{\text{c - 50}}{4} \text{\: (assuming cost to be denoted by c)}[/tex]
Thus, we have the inverse function of given function as:
[tex]n = \dfrac{c-50}{4}[/tex]

Step-by-step explanation:
pablo will rent a car for the weekend. he can choose one of two plans. the first plan has an initial fee of $55.96 with additional costs of $0.12 per mile driven. the second plane has an initial fee of $63.96 and costs an additional $0.08 per mile driven. how many miles does pablo drive to make the miles the same?
Answer:
200 miles
Step-by-step explanation:
First, set up the equations.
plan 1: initial fee of $55.96, $0.12 per mile
y = 0.12x + 55.96plan 2: initial fee of $63.96, $0.08 per mile
y = 0.08x + 63.96We want to know at what distance will the cost be the same. So, set the equations equal to each other.
0.12x + 55.96 = 0.08x + 63.96
Combine the variables.
0.04x + 55.96 = 63.96
Combine the constants.
0.04x = 8
Divide by 0.04 to isolate x.
x = 200 miles
Check by plugging x back into each equation.
y = 0.12(200) + 55.96
y = 24 + 55.96
y = $79.96
y = 0.08(200) + 63.96
y = 16 + 63.96
y = $79.96
You are correct!

Find the equation of the circle centered at $(1,-4)$ with radius 3.
Write your equation in the form "$(x - h)^2 + (y - k)^2 = r^2$".
Answer:
[tex](x-1)^2+(y+4)^2=9[/tex]
Step-by-step explanation:
The equation of a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
The center of the circle is (1, -4).
And the radius is 3.
Substitute:
[tex](x-(1))^2+(y-(-4))^2=(3)^2[/tex]
Simplify. Thus, our equation is:

add 4 on both sides

subtract 100 on both sides
3x+x=84

Use the graph to write the explicit rule of the arithmetic sequence
Answer:
It would be b.
Step-by-step explanation:
Plug in the numbers and try it out yourself. I did it and got b
The explicit rule of the arithmetic sequence is fₙ = 3 + 2(n-1) which is correct option(B).
What is arithmetic sequence?
An arithmetic sequence is defined as an arrangement of numbers which is particular order.
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
According to the graph, we get the sequence
3, 5, 7, 9, ...
Here,
a₁ = 3 is the first element.
An arithmetic sequence has a constant difference 'd' and is defined by
fₙ = a₁ + (n-1)d
computing the differences of all the adjacent terms
5 - 3 = 2, 7 - 5 = 2, 9 - 7 = 2
The difference between all the adjacent terms is the same and equal to
d =2
substituting a₁ = 3 and d = -2 in the nth term of the sequence
fₙ = a₁ + d(n-1)
fₙ = 3 + 2(n-1)
Hence, the explicit rule of the arithmetic sequence is fₙ = 3 + 2(n-1).

Which is an equation in point slope form for the given point and slope? Point: (-3,7) Slope: 4
Answer:
y-7=4x(x+3)
Step-by-step explanation:
(The 4x is 4 times ...)
Answer:
[tex]y -7 = 4(x+3)[/tex]
Step-by-step explanation:
Point-slope form is in the format of [tex]y-y_1 = m (x-x_1)[/tex]. When knowing a line's slope and a point it passes through, you can write an equation in that format. The [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] must be substituted for with real values.
The [tex]m[/tex] represents the slope, thus substitute 4 for [tex]m[/tex]. [tex]x_1[/tex] represents the x-value of one point the line passes through, while [tex]y_1[/tex] represents that same point's y-value. The line passes through (-3, 7), so substitute -3 for [tex]x_1[/tex] and 7 for [tex]y_1[/tex]. This gives the following answer and equation:
[tex]y-(7) = 4(x-(-3))\\y -7 = 4(x+3)[/tex]
