The exact value of the given trigonometric function sin(140°)cos(20°) – cos(140°)sin(20°) is -√3/2.
What are Trigonometric functions?Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.
To find the exact value of sin(140°)cos(20°) – cos(140°)sin(20°), we can use the angle addition formula for sine:
sin(A+B) = sin(A)cos(B) + cos(A)sin(B)
We can use this formula to rewrite the expression as:
sin(140°)cos(20°) – cos(140°)sin(20°) = sin(120°+20°) - sin(120°-20°)
Then, using the angle addition formula for sine, we get:
sin(120°+20°) - sin(120°-20°) = sin(120°)cos(20°) + cos(120°)sin(20°) - sin(120°)cos(20°) + cos(120°)sin(20°)
This simplifies to:
2sin(120°)cos(20°) = 2sin(120°)cos(20°)
The value of sin(120°) is -1/2, and the value of cos(20°) is √3/2, so the final value of the expression is:
2(-1/2)(√3/2) = -√3/2

Distribute 9 to the terms in the brackets.
18n + 9
Add = 0 to solve for x
18n + 9 = 0
Move 9 to the other side by subtracting
18n = -9
Divide by 18 on both sides
n = -9/18
Simplify
n = -1/2
In decimal form the answer can also be -0.5 depending on your question.

You have $1200 to invest in an account and need to have $1900 in one year. What interest rate would you need to have in order to reach this goal if the amount is compounded quarterly? Round your answer to the nearest percent. please help
a. 48.7%
b. 10.5%
c. 8%
d. 44%
Answers
The interest rate that would reach this goal of having $1,900 with the investment of $1,200 compounded quarterly for one year is a) 48.7%.
How is the interest rate determined?The interest rate is the rate at which the present value of $1,200 needs to be compounded quarterly to yield a $1,900 future value in one year.
The interest rate can be computed using an online finance calculator as follows:
Data and Calculations:N (# of periods) = 4 quarters
FV = $1,900.05
PV (Present Value) = $1,200
PMT (Periodic Payment) = $0
Results:
I/Y (Interest per year) = 48.7%
Total Interest = $700.05
Thus, the interest rate that would the investor to achieve their goal is a) 48.7%.

What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
Yolanda jumped 4 3/4 feet = 19/4 feet
and, Jason jumped 6 2/3 feet in a jumping contest. = 20/3 feet
First take the LCM of 3 and 4
LCM( 3, 4) = 12
Then, Yolanda jumped = 19/4 x 3/3 = 57/ 12
and, Jason jumped = 20/3 x 4/4= 80/ 12
Hence, Jason jumped farther by (80/12 - 57/12)= 23/ 12 feet.
