Principal (Money borrowed) = $1,200
Rate = 18% or 0.18 in decimal form
Time = 9 months or 0.75 year.

The gas tank in Margaret's car holds 27 gallons of gas, and she starts out with a full tank. She
drives her car every day, and each day she uses an average of 1.3 gallons. How may gallons wil
she have left after 3 days?
Answer:
She will have 23.1 gallons left after 3 days.
Step-by-step explanation:
We know Margaret uses an average of 1.3 gallons of gas every day and her car holds 27 gallons total. In three days, she would use 3 times her daily average, or 3 * 1.3 = 3.9 gallons consumed in 3 days. To find how many gallons are left in her tank after 3 days, we would subtract 3.9 gallons from 27 gallons. This equals exactly 23.1 gallons of gas.
Write an equation of the line that passes through (-5,4) and is perpendicular to the line that is defined by x-2y=-4
By using the equation of the line and properties of perpendicular lines, we find that the equation of the line is equal to y = - 2 · x - 6.
How to determine the equation of a line
Herein we need to find a line that passes through point (- 5, 4) and is perpendicular to a given line in implicit form: x - 2 · y = - 4. The complete procedure is shown below. First, rewrite the equation of the perpendicular line into explicit form:
x - 2 · y = - 4
2 · y = x + 4
y = (1 / 2) · x + 2
Second, determine the slope of the new line:
m · m' = - 1
(1 / 2) · m' = - 1
m' = - 2
Third, calculate the intercept of the new line:
b = y - m · x
b = 4 - (- 2) · (- 5)
b = 4 - 10
b = - 6
Fourth, complete the new equation of the line:
y = - 2 · x - 6

what are the transformations of this functions compared to the parent function
The technique of altering an existing graph or graphed equation to create a different version of the following graph is known as graph transformation.
Numerous different coordinate systems can be used to describe geometrical figures.
The connection between several systems is defined by coordinate transformations, which offer formulas for the coordinates in one system in terms of the coordinates in another system. The coordinate transformation from polar to Cartesian coordinates is given by the formulas x = r cos and y = r sin, for example, if the polar axis is the positive x axis on the plane and the origins of the Cartesian coordinates (x, y) and polar coordinates (r) are the same.Every bijection from the space to itself can be related to two coordinate transformations.The formulas for the new coordinates of each point's image are constructed in a way that the old coordinates of the original point's image are maintained.In particular, the change of algebraic equations, it is a typical kind of algebraic problem.To learn more about transformation visit:

How much more would the account be worth after 6 years by calculating interest compounded daily versus calculating simple interest? (Assume 365 days in a year.) Do not round until the final answer. Round to the nearest cent.
The account would be worth more after 6 years if calculating interest compounded daily versus calculating simple interest by $62.46
How to calculate compound interest and simple interest?Principal, p = $2,000Interest rate, r = 4% = 0.04Time, t = 6 yearsNumber of periods, n = 365 daysCompound interest:
A = P(1 + r/n)^nt

Step-by-step explanation:
How can you use the Power of a Quotient, Quotient of Powers, Zero Exponent Laws Identity Exponent and to evaluate numerical expressions with whole-number exponents?
The powers can be used in the following manner using multiplicative identity.
Powers are mathematical expressions of the kind where x is the base and n is the exponent. In powers, the exponent specifies how many times to multiply the base by itself whereas the base is the integer or variable that is continuously multiplied.
The quotient rule states that exponents should be subtracted when dividing powers by the same base. For instance, h(6-2) Equals h when h(6) is divided by h(2) (4). Subtracting the exponents is a quick and easy way to simplify the issue.
When separating similar words with exponents, using the Quotient of Powers Rule to minimize the number of terms. This rule states that when dividing words with the same base, the exponents should be removed in order to find the result. When separating similar words with exponents, using the Quotient of Powers Rule to minimize the number of terms. This rule states that when dividing words with the same base, the exponents should be removed in order to find the result. The trick is to eliminate only exponents with compatible bases.

What is the maximum height the ball reaches?
How long is the ball in the air?
The ball reaches a maximum height of 96 feet and it spent 0 seconds in the air
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine the maximum height the ball reaches?The quadratic equation is given as
h(t) = -16t^2 + 96
Differentiate the equation of the function
So, we have
h'(t) = -32t
Set the differentiated function to 0
So, we have
-32t = 0
Divide both sides by -32
So, we have
t = 0
Substitute t = 0 in the equation h(t) = -16t^2 + 96
So, we have
h(0) = -16(0)^2 + 96
Evaluate
h(0) = 96
This means that the maximum height of the ball is 96 feet
How to determine the time spent in the air?Recall that the quadratic equation is given as
h(t) = -16t^2 + 96
Next, we differentiate the equation of the function
So, we have
h'(t) = -32t
Set the differentiated function to 0
So, we have

Divide both sides by -32
So, we have
