Joseph invested $7,850 in an account that pays 7.5% interest per year. How much interest will Juan have earned at the end of 36 months?
Juan have earned of interest after 36 months at the rate of 7.5% interest per year.
What is Simple Interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest. The formula of simple interest is as follows:
S.I = p×r×t
Where p is principle value, r is rate and t is time in years.
Here, the principle amount is $7,850 and rate is 7.5% i.e [tex]\frac{7.5}{100}=0.075[/tex] and time is 36 months i.e 3 years.

Determine the domain and range of the following parabola. f(x)=−3x2−30x−74
Step-by-step explanation:
1. if to rewrite the given equation, then
y= -3(x+5)²+1;
2. the vertex of the parabola is (-5;1) and it is the highest point. Then
3. domain: x is any value, x∈(-∞;+∞);
range: y not greater than 1, y∈(-∞;1].
For the parabola f(x) = -3x² - 30x - 74, the domain is all real numbers (-∞, ∞), and the range is also all real numbers (-∞, ∞).
To determine the domain and range of the given parabola f(x) = -3x² - 30x - 74, we need to understand the behavior of parabolas.
The domain of a function represents all the possible x-values for which the function is defined. In this case, there are no restrictions on the x-values for the given quadratic function. Therefore, the domain is all real numbers, expressed as (-∞, ∞).
The range of a function represents all the possible y-values that the function can produce. For a parabola, if the coefficient of the squared term (in this case, -3) is negative, the parabola opens downward. Since the coefficient is negative, the parabola will have a maximum value. In this example, there is no minimum or maximum specified; thus, the range will also be all real numbers.

for any integer p, show that p^3+11p will always be a multiple of 6
By the principle of mathematical induction, it has been proved that
[tex]p^3 + 11p[/tex] is divisible by 6
What is Principle of mathematical induction?
Let the statement be given by P(n). At first P(n) is proved to be true for 1. Then it is assumed that P(n) is true for all n. If P(n) is true for (n+1) then by Principle of Mathematical induction, P(n) is true for all natural numbers
The given expression is [tex]p^3 + 11p[/tex]
For p = 1
[tex](1)^3 + 11 \times 1\\12[/tex]
which is a multiple of 6
Let it be true for p = m
[tex]m^3 + 11m[/tex] is a multiple of 6
[tex]m^3 + 11m = 6k[/tex], where k is any integer
For p = m + 1

Now,
[tex]m^3 + 11m[/tex] is divisible by 6
We know that the product of two consecutive integers are divisible by 6
[tex]3m(m+1)[/tex] is divisible by 6
12 is divisible by 6
[tex](m+1)^3 + 11(m+1)[/tex] is divisible by 6
So it is true for p = m + 1

y is directly proportional to x3 When x = 10, y = 250
(a) Find a formula for y in terms of x.
The formula for y in terms of x is a cubic equation:
y = 0.25*x³
How to find the relation between x and y?We know that y is directly proportional to x³, then we can write the equation:
y = k*x³
Where k is the constant of proportionality.
In this case, we know that when x = 10, the value of y is 250, then we can replace these values in the above equation to find the value of x:
250 = k*10³
250 = k*1,000

The volume of cone will be [tex]\frac{88r^{3} }{21}[/tex]
Cone:
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base.
Given,
The height of a cone is two times its base diameter.
we have to find the volume of cone in terms of base radius.
let us assume the base radius of cone is equal to r units
so diameter(d) of cone will be, d= 2r units
so,
height(h) of cone will be equal to, h = 2d units
h = 2x2r units
h = 4r units
We know,
Volume of the cone(V) = [tex]\pi r^{2} h/3[/tex]
Where,
r = radius of base
h = height of cone
π = 22/7
Thus by using formula,
Volume of cone(V) = [tex]\pi r^{2} h/3[/tex]
= 22/7 * [tex]r^{2}[/tex] * 4r/3
= 88[tex]r^{3}[/tex]/21

Cost for each pound of chocolate chips is equal to $3.5.
Cost for each pound of walnuts is equal to $1.75
How to determine the cost for each pound of chocolate chips and each pound of walnuts?In order to solve this word problem, we would assign variables to the cost for each pound of chocolate chips and each pound of walnuts respectively, and then translate the word problem into algebraic equation as follows:
Let the variable c represent the amount of cost for each pound of chocolate chips.Let the variable w represent the cost for each pound of walnuts.For 3 pounds of chocolate chips and 2 pounds of walnuts, we have:
3c + 2w = 14 .....equation 1.
For 5 pounds of chocolate chips and 6 pounds of walnuts, we have:
5c + 6w = 28 .....equation 2.
Solving the system of equations by using the elimination method, we have:
3 × (3c + 2w = 14) = 9c + 6w = 42
5c + 6w = 28_
4c = 14
c = 14/4
c = $3.5
For the cost for each pound of walnuts, we have:
3c + 2w = 14
3(3.5) + 2w = 14
10.5 + 2w = 14

Michelle sells new and used kayaks. She makes a 10.5% commission on every kayak she sells and she also gets paid $495.50 per week.
a) Develop an equation for the way Michelle is paid.
b) Last month, the total value of the kayaks she sold was $19 425. Use the equation you’ve developed to find out how much Michelle was paid for that month.
Part a
The equation for the way Michelle is paid is
Total weekly payment y = 495.50 + 0.105x
Part b
The total payment in a month = $4021.625
She makes a 10.5% commission on every kayak she sells
Consider the total value of kayaks she sold = x
The rate of commission = 10.5%
The amount of commission = x × (10.5/100)
= 0.105x
The weekly fixed payment = $495.50
Total weekly payment y = 495.50 + 0.105x
Part b
The total value of the kayaks she sold = $19425
Total number of weeks in a month = 4
Then the total payment in a month = (4 × 495.50) + (0.105×19425)
= 1982 + 2039.625
= $4021.625
Hence,
part a

Total weekly payment y = 495.50 + 0.105x

Then
The distance traveled by Laura in t hours = 12 mph × t hrs = 12t m
The distance traveled by Ashley in t hours = 8 mph × t hrs = 8t m
As we know the distance between Laura and Ashley is 60 miles

What is the equation of a circle with a center at (-4, 0)
that passes through the point (-2, 1)?
O x² + (y + 4)² = √√5
O (x-1)² + (y + 2)² = 5
O (x + 4)² + y² = 5
O (x + 2)2 + (y - 1)² = √5
The equation of a circle with a center at (-4, 0) that passes through the point (-2, 1) is (x + 4)² + y² = 5. Option C is correct.
The standard equation of a circle is given by:
(x – h)² + (y – k)² = r²
Where (h, k) is the center of the circle and r is the radius.
We are given:
The circle has a center at (–4, 0) and passes through the point (–2, 1).
Substitute (h, k) with (–4, 0) in the above equation, we will get;
(x – (-4))² + (y – 0)² = r²
(x + 4)² + y² = r²
Substitute (x, y) with (–2, 1) in the above equation to get the value of r:
(-2 + 4)² + 1² = r²
(2)² + 1² = r²
r² = 5
Put the value r² = 5 in (x + 4)² + y² = r², we will get;
(x + 4)² + y² = 5
So, the equation of the circle is (x + 4)² + y² = 5.
Thus, the equation of a circle with a center at (-4, 0) that passes through the point (-2, 1) is (x + 4)² + y² = 5. Option C is correct.
