The simple interest would be $84.
What is simple interest?
Calculating the interest on a loan using simple interest is quick and simple. Simple interest is calculated by dividing the principle by the daily interest rate and the number of days between installments.
A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest.
Interest = (Principle x Rate x Time in years)/100
= (1200 x 3.5 x 2)/100
= 84
The simple interest would be $84.

Write the slope-intercept form equation of a line that passes through the points (-1,2) and (4,-8).
Answer: y=-2x
Step-by-step explanation: Use the slope formula
-8-2/4-(-1)
-10/5=-2
y=-2
Answer:
y = - 2x
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 2 ) and (x₂, y₂ ) = (4, - 8 )
m = [tex]\frac{-8-2}{4-(-1)}[/tex] = [tex]\frac{-10}{4+1}[/tex] = [tex]\frac{-10}{5}[/tex] = - 2 , then
y = - 2x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (- 1, 2 )
2 = 2 + c ⇒ c = 2 - 2 = 0
y = - 2x + 0 , that is
y = - 2x ← equation of line

Individuals exhibit the dominant traits most prominently. Polydactyly is the dominant condition in this case.
The father has six fingers and six toes, while the mother is in normal condition. In this particular condition, polydactyly is a dominant trait. Twelve percent of the couple's children are expected to have extra digits.

Gary purchased a S750 TV on a credit card with a 22% annual percentage rate, and he wants to pay it off in payments of $200 per month. The table shows the information for the first four months after Gary used his credit card. We need to calculate the values of the missing variables and the total amount he will pay.
The variable "a" is the interest charged on the left amount in the third month.
a = (366.68 - 200)*0.018333 = 3.06
The variable "b" is the monthly amount paid by Gary. It is less than or equal to $200, depending on the payment amount. Since the amount to be paid is $169.74, which is less than $200, he will pay the whole amount in one go.

Determine the convergence of divergence of the sequence. If the sequence converges, find its limit.
The sequence converges and its limit is zero
What is a sequence?A sequence is an ordered set of numbers governed by a rule.
What is the limit of a sequence?The limit of a sequence is the value the sequence approaches
What is convergence of a sequence?The convergence of a sequence is when the sequence approached a definite value
What is divergence of a sequence?The divergence of a sequence is when the sequence does not approach a definite value.
How to determine the convergence of divergence of the sequence?Since we have the sequence (√3 - √1), (√4 - √2), (√5 - √3), (√6 - √2), We need to find the general term of the sequence.
Observing this, we find that the general term Uₙ = √(n + 2) - √n
To determine if the limit converges or diverges, we take the limit of the sequence as n → ∞.
So,
[tex]\lim_{n \to \infty} U_n = \lim_{n \to \infty} \sqrt{n + 2} - \sqrt{n} \\= \lim_{n \to \infty} \sqrt{n + 2} - \lim_{n \to \infty} \sqrt{n} \\= \sqrt{\infty - 2} - \sqrt{\infty} \\= \sqrt{\infty} - \sqrt{\infty} \\= \infty -\infty[/tex]
Since this is an indeterminate form, we use L'hopital's rule to find the limit.
Uₙ = √(n + 2) - √n
= √n{√[(n + 2)/n] - 1}
= √n÷ 1/{√[(1 + 2/n] - 1}
Differentiating, we have
lim n → ∞ Uₙ = lim n → ∞ d√n/dn ÷ d(1/{√[(1 + 2/n] - 1})/dn
= 1/(2√n)/-√[(1 + 2/n] - 1})⁻² × 1/2√(1 + 2/n] × (-2/n²)
= n²[√(1 + 2/n] - 1})²/(2√n)√(1 + 2/n]
= n²[√(1 + 2/n] - 1})²/(2√n)√(1 + 2/n)]
Dividing through by n², we have
= n²[√(1 + 2/n] - 1})²/n² ÷ (2√n)√(1 + 2/n)]/n²
= [√(1 + 2/n] - 1})² ÷ (2(√n)³√(1 + 2/n³)]
Dividing both the numerator and denominator by (√n)³, we have
= [√(1 + 2/n] - 1})²/(√n)³ ÷ (2(√n)³√(1 + 2/n³)]/(√n)³
= (1 + 2/n] - √(1 + 2/n] + 1)/(√n)³ ÷ [2√(1 + 2/n³)]
= (1(√n)³ + 2/n²] - √{(1 + 2/n]/n)³} + 1/(√n)³) ÷ [2√(1 + 2/n³)]
= (1(√n)³ + 2/n²] - √{(1/n³ + 2/n⁴} + 1/√n)³) ÷ [2√(1 + 2/n³)]
So, lim n → ∞ Uₙ = lim n → ∞ (1(√n)³ + 2/n²] - √{(1/n³ + 2/n⁴} + 1/√n)³) ÷ [2√(1 + 2/n³)]
= (1(√∞)³ + 2/∞²] - √{(1/∞³ + 2/∞⁴} + 1/√∞)³) ÷ [2√(1 + 2/∞³)]
= (0 + 0] - √{(0 + 0} + 0) ÷ [2√(1 + 0)]
= (0 - 0 + 0)/2
= 0/2

please answer this quickly this is due by 8pm ;((
Step-by-step explanation:
The drawing has the side dimension of 7.6 cm
since each cm represents 90 m the ACTUAL park is
7.6 x 90 = 684 meters
similarly, the bottom of the drawing has the dimension 9.1 cm which represents 9.1 x 90 = 819 m
the area of the park is then
Area = height x width = 684 m x 819 m = 560 196 m^2
OR in one step:
Area of the actual park is then

waste management company wants to construct a dumpster in the shape of a rectangular solid with no top whose length is four times its width. its volume is fixed at 25.6 yd3. find the dimensions of the dumpster that will minimize its surface area.
the dimensions of the dumpster that will minimize its surface area
length l = 6.32
width w = 1.58
height h = 0.39
Length = l
width = w
height = h
given that length is four times its width
l = 4w
Now, the formula for the surface area of a cube is;
S = 2lh + 2lw + 2wh
substitute l = 4w in the above equation
S = 2(4w)h+2(4w)w+2wh
S = 8wh+8[tex]w^{2}[/tex]+2wh
S = 10wh + 8[tex]w^{2}[/tex]
formula for the volume of a cube is;
V = lwh
now substitute l=4w in the above equation
V = (4w)wh
V = 4[tex]w^{2}[/tex]h
h = 4[tex]w^{2}[/tex]/V
Put V/2w² for h in the surface area equation to get;
S= 8w² + 10w(V/4w²)
= 8w² + 5V/2w
given that volume V = 25.6 substitute that in the above equation
S = 8w² + 5(25.6)/2w
= 8w² + 128/2w
Since we want to minimize the surface area, let us find the first derivative of S to get;
S' = 16w - 128/2w²
At S' = 0
0 = 16w- 128/2w²
16w = 128/2w²
32w³ = 128
w³ = 128/32
w³ = 4
w = [tex]\sqrt[3]{4}[/tex]
w = 1.58 yds
since l = 4w substitute the value of w in that
l = 4(1.58) = 6.32
h = 4[tex]w^{2}[/tex]/V = 4([tex]1.58^{2}[/tex])/25.6

The equation of the trend line in the scatter plot is y = - 4x + 24
What is the slope-intercept form?
Writing the equation of a line in the slope-intercept form simply makes the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) obvious.
Here, we have
The yellow points are located at points (6, 0) and (4, 8)
For a linear equation that passes through the points (x₁, y₁) and (x₂, y₂), the slope is:
s = (y₂ - y₁)/(x₂ - x₁)
Then, for the equation, the slope is
s = (8-0)/(4-6) = -4
Then the linear equation become
y = -4x + b
where b is the y-axis intercept.
To find b, we use that when x = 6, y = 0
0 = 6×(-4) + b
b = 24
Then equation become y = - 4x + 24

The angles of the triangle will be 50°, 70°, 60° .
let the 3 angles of a triangle be A, B and C
The first acute angle A is given by = x + 20
The second acute angle B is given by = 2x + 10
The third acute angle C is given by = 4x - 60
Now we know that the sum of the angles of a triangle is 180°
So ,
A + B + C + = 180°
x + 20 + 2x + 10 + 4x - 60 = 180°
7x - 30 = 180°
7x = 210°
x = 30°
So, from the value of x , we can calculate the value of each angle
Therefore, the required angles are :
angle A = (x + 20)° = 30° + 20° = 50°
angle B = (2x + 10)° = 60° + 10° = 70°

Write a recursive formula: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21
Answer:
[tex]a_1=3[/tex]
[tex]a_n=a_n_-_1+2[/tex]
Step-by-step explanation:
Recursive formula : an = a(n-1) + d
where d = common difference , an = nth term, and n = number of terms
Because we are just writing the recursive formula rather than the explicit formula, the only defined term will be "d" or the common difference.
Here, the common difference is +2. This is evident as you must add 2 to get to 5 and then add 2 to get to 7 etc.
So d = 2
Plugging this into the recursive formula we get an = a(n-1) + 2
Also it's very important to state the first term which is 3 so a1 = 3
