Answer:
Choice C
==> Bank A
Step-by-step explanation:
Principal P = $2000
Bank A calculation
Simple Interest at 5% for 4 years = Prt = 2000 x 5/100 x 4 = $400
Bank B Calculation
At 4% interest compounded quarterly, the accrued value(Principal + Interest) is given by the formula:
[tex]A = P(1 + r/n)^{nt}[/tex]
where
P = principal
r = annual interest rate as percentage
n = number of compounding per year
t = number of years
We have r = 4/ 100 = 0.04
n = 4 since interest is computed quarterly or 4 times a year
t = 4 years
[tex]A = 2000 ( 1 + 0.04/4)^{(4) \cdot (4)}\\\\A = 2000 (1.01)^{16} = \$2,345.16\\\\\text{Interest } = 2345.16 - 2000 = $345.16[/tex]
Since interest earned at bank A (400) > interest earned at bank B(345.16), the answer would be C. ==> Bank A

The outside temperature decreases 7*f in 3 1/2 hours.
How would you represent the temperature as unit
A temperature drop of 7 degrees Fahrenheit in 3.5 hours is represented by 2 f/hour.
What is the definition of Fahrenheit?Fahrenheit temperature scale, based on the freezing point of water at 32° and the boiling point of water at 212°, with the interval between the two divided into 180 equal parts.
Given: The outside temperature drops by 7 degrees Fahrenheit in 3 1/2 hours.
We need to represent the temperature as a unit.
To do so, we must represent the temperature change per hour.

Given the scatter plot on the graph below. What is the slope of the line of fit
Hello there. To solve this question, we'll have to remember some properties about scatter plots and slope of a line.
Given the scatter plot of the data information, we have to determine the slope of the line.
For this, we could determine it numerically using the least squares method, if we knew the data (the coordinates of the points we're plotting the best fit).
In this case, we simply need to find, by inspection, two points contained in the line and use the slope formula.
Given two points (x0, y0) and (x1, y1) that a line L passes through, then the slope m of this line is given by:
[tex]m=\frac{y_1-y_0}{x_1-x_0}[/tex]By inspection, we can easily spot the points (16, 12) and (28, 20).
Plugging these coordinates in the formula, we get:
[tex]m=\frac{20-12}{28-16}[/tex]Add the numbers and simplify the fraction
[tex]m=\frac{8}{12}\overset{:4}{=}\frac{2}{3}[/tex]This is the slope of this line.

What is equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign.
Given:
2m -3 = 3/10 (5m - 12)
Now, cross multiplying
10( 2m -3)= 3( 5m -12)
20m -30 = 15m - 36
20m- 15m= -36 + 30
5m = -6
Divide both side by 5
m= -6/5
Verification:
LHS = 2m-3
=2(-6/5)-3
=-12/5-3
=-27/5
and, RHS
= 3/10( 5m -12)
=3/10(5 x (-6/5) -12)

The apple that costs the least per pound is Apple B.
What is the least cost?The cost per pound for each apple will be calculated as:
= Cost / Weight
Apple A:
= Cost / Weight
= 4.90 / 4
= $1.25 per pound
Apple B:
= Cost / Weight
= $1 / 10
= $0.1 per pound
Apple C:

Explanation:

a)
The slope intercept equation of a line is expressed as
y = mx + c
where
m is the slope
c is the y intercept
The given equation is
x + y = 3
y = - x + 3
By comparing both equations,
m = - 1
If two equations are parallel, it means that they have the same slope. Thus, the slope of the parallel line passing through the point (- 3, 2) is - 1
We would find the y intercept by substituting x = - 3, y = 2 and m = - 1 into the slope intercept equation. It becomes
2 = - 1 * - 3 + c
2 = 3 + c
c = 2 - 3
c = - 1
By substituting m = - 1 and c = - 1 into the slope intercept equation, the equation of the line is
y = - x - 1
b) If two equations are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line Thus, the slope of the perpendicular line passing through the point (- 3, 2) is - - 1/1 = 1
We would find the y intercept by substituting x = - 3, y = 2 and m = 1 into the slope intercept equation. It becomes
2 = 1 * - 3 + c
2 = - 3 + c
c = 2 + 5
c = 5
By substituting m = 1 and c = 5 into the slope intercept equation, the equation of the line is
y = x + 5
a) y = - x - 1
b) y = x + 5
Find the slope of a line parallel to the line whose equation is x-y = 4
Answer: Slope of 1.
Step-by-step explanation:
First, we will put the equation into slope-intercept form.
x - y = 4
x = y + 4
y = x - 4
Our slope, when the line is written as y = mx + b, is the m value. Our m value here is one, so the slope of a line parallel to the line whose equation is x - y = 4 is 1.
I need help with finding the area and the perimeter for a trapezoid thank you
From the figure given in the question, we are asked to find the area and perimeter.
(a) Area:
Since the figure is a trapezoid, the formula for the area of a trapezoid is:
Area = (a + b)h
2
Where:
a = 2
b = 5
h = 4
Area = (2 + 5)4
2
Area = 7/2 * 4
Area = 3.5 * 4
Area = 14 cm²
(b) Perimeter:
To get the perimeter, we will have to add all the side length.
But we will have to find the missin side length first.
Using pythagoras:
a² + b² = c²
Where:
a = 4
b = 3
c² = 4² + 3²
c² = 16 + 9
c² = 25
Taking square of both sides:
c = √25
c = 5
Since we have gotten the missing side length as 5cm, we can now add all the given side length to get the perimeter.
Perimeter = 4 + 2 + 5 + 5
Perimeter = 16 cm

The value of y varies directly with x. When y = 21, x = 3. What is the value of y when x is 14
Answer:
43
Step-by-step explanation:
The value of y varies directly with x. When y = 21, x = 3. What is the value of y when x is 14.
when y = 21 and x = 3 the ratio of y to x is 21 to 3 or (reduced) 3 y to 1 x
This means y is three times the size of x.
When x = 14 then y = 14 × 3 = 42

What are functions?Functions are simply defined as theorems, laws, equation or rules that holds true for the relationship between two variables in a given expression.
The variables are known as;
Independent variableDependent variableGiven the functions as;
f(x)=3x-1 h(x)=-2x^2+3x-9To determine f(73), substitute the value as x in the function, we have;
f(7/3) = 3(7/3) - 1
expand the bracket
f(7/3) = 7 -1
f(7/3) = 6
For h(-2), substitute the value as x in the function, we have;
h(-2) = -2(-2)² + 3(-2) - 9
expand the bracket
h(-2) = -8 -6 - 9
Subtract the values
h(-2) = -23
Now, f(7/3)-h(-2) = 7 --23
f(7/3)-h(-2) = 30
