Answer:
B) 20%
Step-by-step explanation:
Exponential equation:
An exponential equation is given by:
[tex]A(t) = A(0)(1+r)^t[/tex]
In which A(0) is the initial amount and r is the growth rate, as a decimal.
In this question:
[tex]P(t) = 85(1.2)^t[/tex]
Growth rate:
We want to find r, so:
[tex]1 + r = 1.2[/tex]
[tex]r = 1.2 - 1 = 0.2[/tex]
The growth rate is of 0.2 = 2%, and the correct answer is given by option B.
Paulo’s grandfather gave him a collection of 20 coins. Each month Paulo adds 4 coins to his collection. Which inequality can be used to find m, the number of months after starting his collection when Paulo will have more than 50 coins in his collection?
Answer:
[tex]4m+20>50[/tex]
Step-by-step explanation:
Let m represent the amount of months that has passed.
Paulo started out with 20 coins.
Each month, he adds four more coins to his collection.
Therefore, the amount of coins added after m months will be given by 4m.
So, the amount of coins Paulo has total after m months can be given by:
[tex]4m+20[/tex]
We want to know when Paulo will have "more than" 50 coins in his collection. Therefore, we will use the "greater than" sign. Thus, our inequality will be:
[tex]4m+20>50[/tex]
Angle α intersects the unit circle at point (-0.2538, 0.9673). What is the value of tan(α)?
The value of the tan(α) is -0.2624.
What is the tangent of an angle?In trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
In other words, it is the ratio of sine and cosine function of an acute angle such that the value of cosine function should not equal to zero.
Given that, the angle α intersects the unit circle at point (-0.2538, 0.9673). We need to find the value of tan(α),
We know that, the tangent of the angle is the ratio of the perpendicular and the base,
So,
tan(α) = -0.2538 / 0.9673
= -0.2624
Hence, the value of the tan(α) is -0.2624.

The functions f(x) = (x + 5)^2 + 2 and g(x) = -(x − 3)^2−3 have been rewritten using the completing-the-square method. Is the vertex for each function a minimum or a maximum? Explain your reasoning for each function.
Answer:
When the leading coefficient is positive, the graph opens up. It means the vertex is its minimum.
When the leading coefficient is negative, the its vertex is its maximum.

The probability of raining today is equal to the probability of raining on Saturday, which is 0.09.
To find the probability of raining today, given that today is Saturday and the probability of raining on Saturday is 0.09, we can use conditional probability.
The conditional probability of an event A occurring, given that event B has already occurred, is denoted as P(A|B) and is calculated as follows:
P(A|B) = P(A ∩ B) / P(B)
In this case, event A represents the event of raining today, and event B represents the event of it being Saturday.
We are given that P(B) = 0.09 (the probability of raining on Saturday). Since today is Saturday, we know that event B has occurred.
Now, let's assume that event A and event B are independent. This means that the probability of raining today (event A) is not affected by whether it is Saturday (event B) or not.
Under the assumption of independence, we can say that P(A ∩ B) = P(A) * P(B).
Given that P(B) = 0.09, we can substitute these values into the conditional probability formula:
P(A|B) = (P(A) * P(B)) / P(B)
= P(A)
Therefore, the probability of raining today is equal to the probability of raining on Saturday, which is 0.09.

Find the surface area of a right square pyramid with base edge length
2 feet and height 5 feet.
Answer:
24.4 sq. ft.
Step-by-step explanation:
Area of a right square pyramid is:
A = a^2 + 2(a)*square root of ((a^2/4) + b^2)
A = 4 + 4 (square root of ((4/4) + 25) = 4 + 4* square root of 26
A = 4 + 4*5.099
A = 4 + 20.396
A = 24.396 sq ft.

Jane's monthly payment this year using balance billing would be $164 per month.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
To determine Jane's monthly payment this year using balance billing, we need to divide the total amount she spent last year ($1,968) by the number of months in a year.
Total amount spent last year = $1,968
Number of months in a year = 12
So, Monthly payment = Total amount spent last year / Number of months in a year
Monthly payment = $1,968 / 12
Monthly payment ≈ $164
Therefore, Jane's monthly payment this year using balance billing would be $164 per month.
