Answers
We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the following exponential function: [tex]y = 48000(0.76)^t[/tex] where y represents the car's value and t represents time in years. We are asked to find the decay rate as a percentage.
We know that an exponential decay function is in form [tex]y=a\cdot (1-r)^x[/tex], where,
y = Final value,
a = Initial value,
r = Decay rate in decimal form,
x = time.
Upon comparing our given function [tex]y = 48000(0.76)^t[/tex] with standard decay function [tex]y=a\cdot (1-r)^x[/tex], we can see that [tex]1-r=0.76[/tex].
Let us solve for r.
[tex]1-1-r=0.76-1[/tex]
[tex]-r=-0.24[/tex]
[tex]r=0.24[/tex]
Let us convert 0.24 into percentage.
[tex]0.24\times 100\%=24\%[/tex]
Therefore, the decay rate is 24%.

Answers
Answer:
C. 16√3π in.
Step-by-step explanation:
Circumference of a circle = 2πr where
r is the radius of the circle.
Given the area of one of the smaller circle to be 48π in², we can get the radius of one of the smaller circle.
If A = πr²
48π = πr²
r² = 48
r = √48 in
The radius of one of the smaller circle is √48.
To get the circumference of the larger circle, we need the radius of the larger circle. The radius R of the larger circle will be equivalent to the diameter (2r) of one of the smaller circle.
R = 2r
R = 2√48 inches
Since C = 2πR
C = 2π(2√48)
C = 4√48π in
C = 4(√16×3)π in
C = 4(4√3)π in
C = 16√3π in
Thw circumference of the larger circle is 16√3π in.
Step-by-step explanation:
Given two circa inscribed side by side inside a big circle, it is notice that the internal two circle are identical and diameter of the one the internal circles is equal to the radius of the big circle
So, we are given the area of one of the small circle, so from their we can find the radius of the small circle.
Area of small circle
A = 48π in²
Area of a circle is given as πr²
A = πr²
48π = πr²
Divide both side by π
48 = r²
Take Square root of both sides
r = √48 = √(16 × 3)
r = 4√3 in
Then, the diameter of the small circle is
d = 2r = 2 × 4√3
d = 8√3
So, the radius of the big circle is
R = d = 8√3
So, we want to find the perimeter of the big circle
The perimeter of a circle is calculated using
Perimeter = 2πr
P = 2πR
P = 2π × 8√3
P = 16π√3 in
So the correct option is C
P = 16√3 π in.

Which of the following is not a property for all parallelograms?
A. Opposite sides are parallel.
B. All sides have the same length.
C. Opposite angles are congruent.
D. The diagonals bisect each other.
Answers
Answer:
B. All sides have that same length, would be the correct answer.
Step-by-step explanation:
Answers A,C, and D are all properties for all parallelograms.
Option B, which states that all sides have the same length, is not a property for all parallelograms. It is only true for rhombuses, which are a special type of parallelogram.
Explanation:Among the options given, the one that is not a property for all parallelograms is:
B. All sides have the same length.This statement is not true for all parallelograms; it is a specific property of a subset of parallelograms known as rhombi (singular: rhombus), where all four sides are congruent. However, a general parallelogram only requires opposite sides to be of equal length, not all four sides. To clarify further:
Opposite sides are parallel - True for all parallelograms.Opposite angles are congruent - True for all parallelograms.The diagonals bisect each other - True for all parallelograms.The key distinction here is understanding that while rhombi share all the properties of parallelograms, not all parallelograms are rhombi.
If f(1)=9 and f(n)=f(n-1)+2 then find the value of f(5)
Answers
Answer:
Step-by-step explanation:
hello :
f(n)=f(n-1)+2
means : f(n)-f(n-1)=2
this is the arithmetic seq when the common dif is d= 2 and the first term is : 9
the n-ieme term is : f(n) = f(1) +(n-1)d
f(n) =9+2(n-1)
f(n) = 2n+7
so : f(5) = 2(5)+7 = 17
Final answer:
The value of f(5) is determined by consecutively applying the given recursive relation, f(n) = f(n-1) + 2, starting from the initial condition f(1) = 9. After applying this process four times, we find that f(5) is 17.
Explanation:
f(1) = 9
f(n) = f(n-1) + 2
To find the value of f(5), we can use the recursive formula provided:
f(2) = f(1) + 2 = 9 + 2 = 11
f(3) = f(2) + 2 = 11 + 2 = 13
f(4) = f(3) + 2 = 13 + 2 = 15
f(5) = f(4) + 2 = 15 + 2 = 17
what is the slope of the line that passes through the points (2,4) and (6,12)
Answers
Answer:
12
Step-by-step explanation:
because yes
Answer: 2
Explanation: To solve this problem, it's important to understand that we don't need to graph the line but we can use our slope formula. One method you could use is the graphing method which requires you to plot the points but I will be showing you the slope formula.
[tex]m =\frac{ ^{y}2 - ^{y}1 }{x^{2} - x^{1} }[/tex]
We take our second y minus our first y
which in this case is 12 - 4
over our second x minus our first x
which in this case is 6 - 2.
So 12 - 4 over 6 - 2 simplifies to 8/4.
Notice that our slope can
be simplified one step further.
So 8/4 reduces to 2.
So the slope of the line that passes through these points is 2.

Find the midpoint m of AB
Answers
The midpoint m of line segment AB, with a length of 22 units, is located at 11. Assuming A and B are evenly spaced, the midpoint is found using the formula [tex]\( m = \frac{{A + B}}{2} \)[/tex].
To find the midpoint m of line segment AB, where AB has a length of 22 units, we use the midpoint formula: [tex]\( m = \frac{{A + B}}{2} \)[/tex].
Here, A and B are the coordinates of the endpoints of AB.
Since no specific coordinates are provided, let's assume A and B are equally spaced on the line.
If A = 0 and B = 22, the midpoint m would be [tex]\( \frac{{0 + 22}}{2} = 11 \)[/tex].
Therefore, the midpoint of AB is 11.
To find the midpoint of line segment AB, use the midpoint formula by averaging the x-coordinates and y-coordinates of the endpoints A and B.
Explanation:The midpoint of a line segment AB can be found by using the midpoint formula. The formula is:
(x1 + x2) / 2, (y1 + y2) / 2
where (x1, y1) and (x2, y2) are the coordinates of points A and B respectively.
Plug in the values for the coordinates of A and B, and calculate the midpoint coordinates.
The question asks to find the midpoint of a line segment AB. To find this midpoint, one would typically use the midpoint formula, which is derived from the average of the x-coordinates and y-coordinates of the endpoints of the segment. The question seems to be associated with a geometry or physics context, but the process to find the midpoint remains the same. It involves adding the x-coordinates of both endpoints and dividing by 2 to find the x-coordinate of the midpoint, and doing the same with the y-coordinates for the y-coordinate of the midpoint.

[tex]4(x-5)=35[/tex]
[tex]4x-20=35[/tex]
[tex]4x=35+20[/tex]
[tex]4x=55[/tex]
Therefore, [tex]4(x-5)=35[/tex] is not equivalent to [tex]4x=40[/tex].
Hence, option (a) is correct.

A square napkin is folded in half on the diagonal and placed on the diameter of a round plate (see diagram below). If the folded napkin spans the plate and the plate has an 18-inch diameter, what is the area of the space on the plate that is NOT covered by the napkin? Leave your answer in terms of .
Answers
Answer:
[tex]A=81(\pi-1)\ in^2[/tex]
Step-by-step explanation:
step 1
Find the area of the plate
The area of a circle is given by the formula
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=18/2=9\ in[/tex] ---> the radius is half the diameter
substitute
[tex]A=\pi (9)^{2}\\A=81\pi\ in^2[/tex]
step 2
Find the area of the square napkin folded (is a half of the area of the square napkin)
we know that
The diagonal of the square is the same that the diameter of the plate
Applying Pythagorean theorem
[tex]D^2=2b^2[/tex]
where
b is the length side of the square
we have
[tex]D=18\ in[/tex]
substitute
[tex]18^2=2b^2[/tex]
solve for b^2
[tex]b^2=162\ in^2[/tex] -----> is the area of the square
Divide by 2
[tex]162/2=81\ in^2[/tex]
step 3
Find the area of the space on the plate that is NOT covered by the napkin
we know that
The area of the space on the plate that is NOT covered by the napkin, is equal to subtract the area of the square napkin folded (is a half of the area of the square napkin) from the area of the plate
so
[tex]A=(81\pi-81)\ in^2[/tex]
simplify

Two farmhouses A and B are 10.3 km apart. A third farmhouse C is located such
that angle A=83◦ and angle B=59◦. How far is C from A?
Answers
Answer:
Distance between A to C is 16.62km
Step-by-step explanation:
See attached document to get a better illustration of the angle.
A = 83°
B = 53°
C = ?
180° = 83° + 53° + C (sum of angles in a triangle is equal to 180°)
180° = 142° + c
C = 180 - 142
C = 38°
To find the distance AC, we have to use sine rule.
a / sin(A) = b / sin(B) = c / sin(C)
a / sin(A) = c / sin(C)
a /sin83 = 10.31 / sin38
Cross multiply
10.31 * sin83 = a * sin38
10.23 = (0.61566)a
a = 10.23 / 0.61566
a = 16.616 km
a = 16.62km
The distance between A and C is 16.62km
