Lana bought a sports car for $75,700. If the value of her car decreases 4.3% annually.
When using the exponential DECAY formula, what would be the value of r?
Answer:
The value of r will be 0.043
Step-by-step explanation:
Firstly, we need to write the exponential decay formula
the general form of the formula is;
A = P(1-r)^t
where A is the price after a certain year t
P is the initial value
r is the decay rate
t is the time
From the question, we have that;
r = 4.3%
4.3% in decimal will be 4.3/100 = 0.043

A circle is centered on point B. Points A, C and D lie on its circumference.
If ZABC measures 46°, what does ZADC measure?
Step-by-step explanation:
given: B is the centered poin of the circle
points A,C,D lies on its circumference
measure angle ABC is 46⁰
<ADC is inscribed in the circle
<ABC is the central angle
to find: what is the measure of angle ADC?
solution:
inscribed angle therom states that an inscribe angle is half of a central angle that subtends the same arc
hence, <ADC = 1/2 × <ABC
<ADC= 1/2 × 46⁰
<ADC=1/2 ×46⁰
<ADC= 23⁰

Answer:
x = 11
Step-by-step explanation:
Assuming that segment EG is a diameter we can solve this using the straight angle theorem ( Which states that angles on a straight line add up to equal 180. Also note that central angles and there corresponding arcs are congruent. )
We are also told that CH is a bisector.
A bisector splits an angle into TWO EQUAL parts.
mDG is split into mDC and mCG
So mDC = mCG
This meaning that because mDC = 7x + -1 , mCG also equals 7x - 1
Leading to us having enough information to use the straight line theorem ( which also works with half circles and arcs. )
So 180 = 2 ( 7x - 1 ) + 2x + 6
now we solve for x
step 1 distribute the 2
2 * 7x = 14x
2 * - 1 = -2
now we have 180 = 14x - 2+ 2x + 6
step 2 combine like terms
14x + 2x = 16x
-2 + 6 = 4
now we have 180 = 16x + 4
step 3 subtract 4 from each side
4 - 4 cancels out
180 - 4 = 176
Now we have 176 = 14x
step 4 divide each side by 14
176 / 16 = 11
14x/14 = x
we're left with x = 11

Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P′Q′R′S′. Which rule describes this transformation? F.(x, y) → (x — 5, y — 3) G.(x, y) → (x + 5, y + 3) H.(x, y) → (x — 3, y — 5) J.(x, y) → (x + 3, y + 5)
Answer:
G.(x, y) → (x+5, y+3)
Step-by-step explanation:
The rule would be (x+5, y+3) and the only one with that rule is G.

Based on these results, estimate the probability that 3 or more kicks are made.
Answer:
You are correct that the cross section is a rectangle, because a rectangular pyramid has 4 sides connected to the top of the rectangle.
Step-by-step explanation:
We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.
What is simulation?Simulation is the process of creating a computer model or a physical system that behaves like a real-world system or process, in order to study its behavior or performance under various conditions.
We have,
To estimate the probability that 3 or more kicks are made, we need to count the number of trials in which 3, 4, or 5 kicks were made, and divide that by the total number of trials (which is 5 in this case).
From the table,
We can see that there are three trials in which 3 kicks were made
(trials 1, 3, and 5), one trial in which 4 kicks were made (trial 4), and no trials in which all 5 kicks were made.
The total number of trials in which 3 or more kicks were made is:
= 3 + 1 + 0
= 4
To estimate the probability, we divide the number of successful trials by the total number of trials:
P(3 or more kicks made) ≈ 4/5
Therefore,
We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.

jim invested in a savings bond for 6 years and was paid simple interest at an annual rate of 3%. the total interest that he earned was $540. how much did he invest?
Answer:
the principal or invested amount is $457.63
Step-by-step explanation:
The computation of the invest amount is given below:
As we know that
Principal = AMount ÷ (1 + rate × time)
= $540 ÷ (1 + 0.03 × 6)
= $540 ÷ 1.18
= $457.63
Hence, the principal or invested amount is $457.63
Basically we have applied the above formula so that the same would be calculated

Which of the following are true if event A and B are independent
Answer:
a) [tex]P(B/A) = P(B)[/tex]
Step-by-step explanation:
Step(i):-
Given that A and B are independent events
P(A∩B) =P(A) P(B)
we will use the conditional probability
[tex]P(A/B) = \frac{P(AnB)}{P(B)}[/tex]
or
[tex]P(B/A) = \frac{P(AnB)}{P(A)}[/tex]
Step(ii):-
Given that A and B are independent events
P(A∩B) =P(A) P(B)
[tex]P(B/A) = \frac{P(AnB)}{P(A)}[/tex]
[tex]P(B/A) = \frac{P(A)P(B)}{P(A)} = P(B)[/tex]
[tex]P(B/A) = P(B)[/tex]
how do you find the scale factor in enlargement
Answer/Step-by-step explanation:
Scale factor is the ratio of the corresponding side lengths of two similar figures or shapes.
For an enlargement, divide the length of the new figure over the length of the original figure.
The scale factor of an enlargement should give you a whole number or mixed fraction.
For example, if the length an original figure is 2, and the length when enlarged is 6, the scale factor = 6/2 = 3

Answer:
Quadrilateral ABCD is a rhombus, because all four sides are congruent and adjacent sides are not perpendicular .
Step-by-step explanation:
Given :
A quadrilateral with its coordinates as follows:
Where A (3, 1), B (4,4), C (7,5), D (6,2).
We will measure the length of the congruent sides by applying distance formula.
Distance formula = square root (x^2 - x^1)^2 + (y^2 - y^1)^2
So,
AB = ( insert the coordinates using the formula )
BC = ( insert the coordinates using the formula )
CD = ( insert the coordinates using the formula )
DA = ( insert the coordinates using the formula )
It all equals = squareroot 10
From the above measurement and looking into the diagram we can conclude that the Quadrilateral ABCD is a rhombus.
In rhombus the adjacent sides are not perpendicular and its diagonals are of different length.
