Because there's no picture provided, I can just give two points in order to formulate the equation using the point-slope formula. The x is in years while the y is in percentage. Suppose point 1 is (2, 35) and point 2 is (7,80).
Point Slope Formula: y - y₁ = [(y₂ - y₁)/(x₂ - x₁)](x - x₁)
Substituting,
y - 35 = [(80 - 35)/(7 - 2)](x - 2)
y - 35 = 9(x - 2)
R = 8%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/2)((2320/2000) - 1) = 0.08
r = 0.08
Converting r decimal to R a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to get a total amount, principal plus interest, of $2,320.00 from simple interest on a principal of $2,000.00 over 2 years is 8% per year.

Answer:
C. 3/2 Radians
Step-by-step explanation:
As we know, a radian is defined as "the angle enclosed by an arc equal to the radius", or some variant of such.
This means 1 radian in this circle would have an arc length of 8cm.
Simple proportions should get you an answer:
Answer: The required equation is
Step-by-step explanation: We are given to write the following statement as an equation :
"The sum of one-third of a number, one-half of a number and twice the number is thirty-four".
Let the number be represented by x.
Then, one-third of the number is one-half of the number is and twice the number is
Therefore, as an equation, the given statement is written as:
Thus, the required equation is
